Brief summary:
This study is designed to explore the potential of the epigenetic agent RRx-001 to sensitize patients who previously received and now have failed a platinum based doublet regimen. RRx-001 is administered with autologous blood once weekly followed by or in combination with reintroduction of platinum-based doublet therapy.

Detailed description:
This is an open label, four 'cohort' study for administration of RRx-001 with autologous blood once weekly followed by or in combination with reintroduction of platinum-based doublet therapy according to the treatment schedule listed below. Small cell carcinoma and ovarian cohort participants will be randomized to 1 of 2 treatment arms, respectively. Neuroendocrine and NSCLC patients will be enrolled to single arms.

Participants with SCC will receive one of the following; RRx-001 followed by platinum doublet chemotherapy or platinum based chemotherapy alone. HGNEC, RRx-001 followed by platinum doublet chemotherapy. NSCLC, RRx-001 followed by platinum doublet chemotherapy. Participants with Platinum Refractory/Resistant Ovarian and MMMT will receive one of the following, RRx-001 followed by platinum doublet chemotherapy or chemotherapy alone.

Approximately 213 participants will be enrolled.

Arms:
arm 1: RRx-001 weekly for 3 weeks followed by up to 4 cycles of carboplatin or cisplatin plus etoposide and then RRx-001 and carboplatin or cisplatin (for patients with stable disease (SD) or better at discontinuation of platinum). arm 2: Carboplatin or cisplatin plus etoposide or irinotecan or vinorelbine until progression or intolerable toxicity arm 3: RRx-001 weekly for 3 weeks followed by up to 6 cycles of cisplatin or carboplatin plus paclitaxel or nab-paclitaxel or pemetrexed and then RRx-001 maintenance (for patients with stable disease or better at discontinuation of platinum). arm 4: RRx-001 weekly until progression followed by up to 6 cycles of carboplatin or cisplatin plus etoposide and then RRx-001 maintenance (for patients with stable disease or better at discontinuation of platinum). arm 5: RRx-001 weekly for 2 weeks followed by 2 cycles of Carboplatin chemotherapy and then RRx-001/Carboplatin maintenance (for patients with stable disease or better at discontinuation of platinum). arm 6: Carboplatin, Etoposide, Doxil, Gemcitabine or Vinorelbine or Taxane until progression or intolerable toxicity

Interventions: intervention 1: RRx-001 intervention 2: Cisplatin intervention 3: Etoposide intervention 4: Carboplatin intervention 5: Irinotecan intervention 6: Vinorelbine intervention 7: Doxil intervention 8: Gemcitabine intervention 9: Taxane intervention 10: Paclitaxel intervention 11: Nab-Paclitaxel intervention 12: Pemetrexed

2 STUDY SUMMARY 
Title: 
RRx-001 in patients with small cell carcinoma, high-grade neuroendocrine carcinoma, EGFR 
mutation positive non-small cell lung cancer, ovarian cancer (including Malignant Mixed 
Mullerian Tumor (MMMT) of the ovary or uterus) previously treated with a platinum-based 
regimen (QUADRUPLE THREAT) 
Descriptive Title: 
RRx-001 for Sensitization/Resensitization to Platinum Based Chemotherapy in Gynecologic, 
Thoracic, and Extrathoracic Malignancies in Patients Who Previously Received and 
Eventually Progressed on or after a Platinum Doublet Regimen 
Phase: 
Phase 2 Study 
Methodology: 
The study is designed to explore the potential of the epigenetic and tumor associated 
macrophage (TAM)-targeting agent RRx-001 to sensitize patients who previously received 
and now have progressed on a platinum based doublet regimen. This is an open label study 
for administration of RRx-001 with autologous blood.  
Small cell carcinoma and ovarian cohort patients will be randomized to 1 of 2 treatment arms, 
respectively.  Neuroendocrine and NSCLC patients will be enrolled to single arms, 
respectively, as stated below.  
SCC cohort patients (enrolled as of Amendment 10) will be randomized (2:1) to 1 of 2 
treatment arms:  
Arm 1): RRx-001 weekly for 3 weeks followed by up to 4 cycles of platinum plus 
etoposide chemotherapy ‘rechallenge’ and then RRx-001 & platinum maintenance (for 
patients with stable disease (SD) or better at discontinuation of platinum rechallenge) 
Arm 2): Standard of Care Investigator’s Choice Control Arm, treatment options of one 
of the following: platinum plus etoposide, irinotecan or vinorelbine until progression or 
intolerable toxicity  
Ovarian cohort patients (enrolled as of Amendment 10) will be randomized (2:1) to 1 of 2 
treatment arms: 
Arm 1): RRx-001 weekly for 2 weeks followed by 2 cycles of carboplatin ‘rechallenge’ 
and then ‘maintenance’, cycling between 1 dose of RRx-001 followed by 2 cycles of 
carboplatin, which repeats until progression or intolerable toxicity 
Arm 2): Standard of Care Investigator’s Choice Control Arm, treatment options of one 
of the following: carboplatin, etoposide, doxil, gemcitabine, vinorelbine or taxane 
treatments until progression or intolerable toxicity 
Neuroendocrine cohort patients: Will receive RRx-001 weekly until progression followed 
by up to 6 cycles of platinum doublet chemotherapy. 
 Maintenance RRx-001 is given for patients with stable disease or better at 
discontinuation of platinum and administered weekly (QW) until progression.  
NSCLC cohort patients: Will receive RRx-001 weekly for 3 weeks followed by up to 6 
cycles of platinum doublet chemotherapy. 
 Maintenance RRx-001 is given for patients with stable disease or better at 
discontinuation of platinum and administered weekly (QW) until progression.

Objectives: 
Primary Objective 
To evaluate Overall Survival (OS) and Overall Response Rate (ORR).  
Secondary Objectives 
• To estimate the transition probability between disease progression and disease 
amelioration attributable to resensitization   
• To estimate the mean sojourn time in a platinum sensitized state 
• To evaluate disease control rate (DCR) and PFS by RECIST v1.1 criteria in adult 
patients with advanced or metastatic SCC, NSCLC, EOC or HGNEC after re-treatment 
with platinum-based therapy following exposure to RRx-001 
• To evaluate the toxicity of RRx-001 monotherapy 
• To evaluate the toxicity of platinum-based therapy following prior exposure to these 
agents and treatment with RRx-001 monotherapy 
Exploratory Objectives 
• To investigate:  
o Circulating Tumor Cells 
o Circulating Endothelial Cells (CEP and CEC) 
o Immune Subsets 
o Epigenetic markers e.g., Protein Hyperacetylation and gene methylation 
o Status of tumor suppressors such as p53, pre and post RRx-001 
o Expression of TGF-beta and its receptor and fibrosis status pre and post dose of 
RRx-001. 
o Relative density of tumor associated macrophages in patient biopsies 
o Status of microRNAs (miRNAs) pre and post RRx-001.  
o To evaluate changes in a panel of tumor biomarkers. (i.e., CA-125 for ovarian cancer 
and chromogranin A and neuron specific enolase (NSE) for neuroendocrine tumors) 
o To evaluate the overall response rate (ORR), disease control rate (DCR) and PFS by 
immune response criteria in adult patients with advanced or metastatic SCC, NSCLC, 
EOC or HGNEC during RRx-001 treatment period

stable disease during first-line treatment or who relapse within 1 month are 
considered to be 'platinum-refractory'. Patients who respond to primary treatment 
and relapse within 6 months are considered 'platinum-resistant', and patients who 
relapse more than 6 months after completion of initial therapy are characterized as 
'platinum-sensitive'. Patients who relapse 6-12 months following the end of their 
initial regimen are classified as 'partially sensitive’. 
D. High-Grade Neuroendocrine Carcinoma (HGNEC), any organ of origin, including a 
pathology of neuroendocrine features, in patients previously been treated with 
chemotherapy  
i. Although neuroendocrine tumors may be classified differently based on organ of 
origin, in the context of this protocol they are defined as high grade on the basis 
of either 
1. Aggressive clinical behavior requiring previous treatment with chemotherapy 
even if histologic features such as the Ki67 index or mitotic rate corresponds 
with low or intermediate grade. 
2. Histologic features:

Statistical 
Analysis: 
Primary Efficacy Endpoints: 
OS is defined as the time from enrollment to date of death, and its analysis will be similar to 
PFS in an intent-to-treat (ITT) population.  
The Kaplan-Meier estimate of the active cohort survival curve, its median survival times 
(with 95% confidence CI) will be derived.  A hazard ratio will be estimated using the 
historical control (as a reference). The hazard ratio (HR) and its 95% CI will be calculated. 
Overall response rate (ORR) of re-introduced platinum therapy, which will be calculated as 
confirmed response (CR + PR).  
The treatment effect on ORR will be quantified using the odds ratio.  Clopper-Pearson 2-
sided 95% confidence limits will be calculated. ORR analyses will be performed for the 
Efficacy Evaluable population.  Patients who do not have measurable disease at baseline will 
be excluded from the population.  
Secondary Efficacy Endpoints: 
The transition probability between disease progression and disease amelioration attributable 
to sensitization/resensitization will be estimated. A semi-Markov chain model will be used to 
capture the transition probability matrix between disease progression states. The average time 
each patient spends in a given disease state will be estimated (mean sojourn time) and its 95% 
confidence interval derived. The expected time spent healthy (or diseased) before death will 
also be estimated. 
The analysis of PFS will be similar to OS. Patients will be followed until their date of death, 
loss to follow-up, withdrawal of consent for further follow-up for survival, or final database 
closure.  Patients who are lost-to-follow-up or are not known to have disease progression at 
the time of data-cut-off for analysis will be censored at last date shown to be alive. Patients 
who do not have any follow up since enrollment will be censored at the date of enrollment.

Amendment 10 Statistical updates:  
General design considerations, effective as of Amendment 10:  
1. Small Cell Carcinoma: Newly enrolled patients (post Amendment 10) will be allocated 
to one of two treatment arms using a 2-to-1 randomization ratio,(approximately 26 to 
Arm 1 and 13 to Arm 2). 
The two treatment arms are as follows:  
Arm 1: RRx-001 weekly for 3 weeks followed by up to 4 cycles of platinum plus 
etoposide chemotherapy ‘rechallenge’ and then RRx-001 & platinum maintenance (for 
patients with stable disease (SD) or better at discontinuation of platinum rechallenge) 
Arm 2: Standard of Care Investigator’s Choice Control Arm, treatment options of 
platinum plus etoposide, irinotecan or vinorelbine until progression or intolerable 
toxicity 
2. Ovarian: Newly enrolled patients (post Amendment 10) will be allocated to one of two 
treatment arms using a 2-to-1 randomization ratio (approximately 26 to Arm 1 and 13 
to Arm 2). 
The two treatment arms are as follows: 
Arm 1: RRx-001 weekly for 2 weeks followed by 2 cycles of carboplatin 
‘rechallenge’ and then ‘maintenance’, cycling between 1 dose of RRx-001 followed by 
2 cycles of carboplatin, which repeats until progression or intolerable toxicity 
Arm 2: Standard of Care Investigator’s Choice Control Arm, treatment options of one 
of the following: carboplatin, etoposide, doxil, gemcitabine, vinorelbine or taxane 
treatments until progression or intolerable toxicity 
3. Neuroendocrine: The only modification with Amendment 09 forward to the existing 
treatment schedule is the addition of a RRx-001 maintenance for patients with > SD  
following discontinuation of platinum based chemotherapy (for up to 6 cycles).  
4. NSCLC: Patients enrolled post amendment 09 will receive 3 consecutive doses of 
RRx-001, after which, RRx-001 is discontinued and platinum based chemotherapy is 
started for up to 6 cycles. In addition, a RRx-001 maintenance for patients with > SD 
following discontinuation of platinum based chemotherapy (for up to 6 cycles) was 
added.

Sample size determination and power considerations: 
The extension stage of the study will approximately enroll 39 patients to the small cell 
carcinoma cohort and also 39 patients to the ovarian cohort. In each cohort, a 2-to-1 
randomization allocation ratio will be employed (approximately 26 in Arm 1 and 13 in Arm 
2, in each cohort). The proposed sample size modification is motivated by recent clinical 
observations arising from current study data results. This upward sample size adjustment 
should provide sufficient precision to derive estimates of responses and time-to-event 
endpoints. Inferential statistics are not the main focus of this newly proposed focus study 
extension. 
Analysis of Activity Data: 
Descriptive statistics arranged by treatment group (within each of the four cohorts) are 
planned. Graphical depiction of the statistical summaries (ORR, DCR, OS, PFS) will 
accompany the tabular formatted data results for a more complete presentation of the 
statistical findings. Specifically, Kaplan-Meier curves and estimation of time-to-event 
medians with their corresponding 95% confidence intervals will be produced. ORR and DCR 
responses will be derived and the Clopper-Pearson method will be used to derive the 
responses 95% confidence intervals. 
Standard safety data will include adverse events (AEs), serious adverse events (SAEs), ECOG 
performance scale, clinical laboratory tests, vital signs and physical examination results. 
Safety summaries will use the safety population and will be presented separately by treatment 
group (within cohort) and across all cohorts aggregated. All safety data will be presented in 
data listings.  
AEs will be coded by system organ class (SOC) and preferred term using MedDRA, version 
14.1; severity will be based on NCI CTCAE Grade (version 5.0). Incidence of TEAEs by 
MedDRA SOC, preferred term and relationship (Related/Not Related) to study drug will be 
summarized based on the safety population. Adverse event incidence rates will be 
summarized using frequency and percentage. Adverse event data will be descriptively 
evaluated by treatment arm and for overall patients. 
Study Product(s), 
Dose, Route, 
Regimen: 
RRx-001 Drug Product is supplied as a sterile solution in PEG-400. Prior to administration, 
Diluent for RRx-001, DMA, will be added to RRx-001 Drug Product to yield a solution 
containing 66% PEG-400 and 33% DMA. This solution will then be diluted to 2.0 mg/mL 
with Water for Injection (WFI).  
The dose in this trial will be 4 mg, based on ongoing evidence of activity. The dose of 4 mg 
translates to 2 mL, which will be mixed with an aliquot of autologous blood and 
anticoagulant and re-infused into the patient once a week over an expected time period of less 
than an hour. The procedure is described in detail in the latest version of the ‘Blood 
Administration Best Practices & Guidelines for IV Infusion of RRx-001 + Blood Mix’ guide. 
All doses of RRx-001 will be administered on an open-label basis.   
Following treatment with RRx-001, one of the regimens referenced in the methodology 
section will be administered. 
Duration of 
administration: 
In the absence of treatment delays due to adverse events, RRx-001 treatment may continue as 
outlined in the assigned cohort schema or until disease progression, unacceptable toxicity or 
physician discretion.  Per the standard of care, the platinum based therapy will be given for 
two cycles of therapy and, if tumor assessments show stable disease or a partial response, an 
additional two cycles of chemotherapy will be given.

3 BACKGROUND AND RATIONALE 
3.1 Background 
Lung cancer is the leading cause of death among men and women in North America (Jemal, 
2009).  An estimated 172,016 subjects have been diagnosed with non small cell lung cancer 
(NSCLC) in 2009 (Jemal, 2009).  Of these subjects more than 55% will present with advanced 
stage disease (stage IV or stage IIIB) that is not amenable to curative treatment. Of the remaining 
45% that are treated with curative intent only 20% of these will undergo surgery while the 
remaining will be treated with definitive chemoradiation.  More than half of these subjects will 
relapse and eventually succumb to their disease.   
1. EGFR+ NSCLC: For EGFR-mutation-positive NSCLC patients who progress on tyrosine 
kinase inhibitors (TKIs), the most common cause (in 60% of patients) is a second site exon 
20 EGFR mutation in the kinase domain of EGFR called T790M (the “gatekeeper” 
mutation), which prevents drug from binding to the receptor. Several mutant-selective TKIs, 
including rocelitinib and osimertinib, inhibit both activating mutations as well as the T790M 
gatekeeper resistance mutation, but do not target wild type (WT) EGFR. Preliminary clinical 
results from these agents indicate high response rates with long duration in T790M+ cases of 
acquired resistance. By contrast, the optimal treatment for patients with T790M negative 
resistance to EGFR TKIs remains unclear. Histologic and molecular investigations of tumor 
tissue obtained at progression have revealed multiple mechanisms of resistance. These 
include transformation to a small cell histology or epithelial-to-mesenchymal transformation; 
amplification of other receptor tyrosine kinases including MET, HER2 and WT EGFR; and 
point mutations in downstream genes including PIK3CA and BRAF. Thus, NSCLC patients 
who have failed treatment with TKIs and whose tumors do not express the T790M mutation 
represent a group with fatal disease and unmet need. (Yu, 2013) 
The current chemotherapy standard for subjects with advanced NSCLC is one of a number of 
platinum-based doublets; however, in the United States the most commonly used 
combination is solvent-based paclitaxel (sb-paclitaxel) plus carboplatin.  The 130-nm 
albumin-bound formulation of paclitaxel (nab-paclitaxel [Abraxane]), which may reach the 
tumor microenvironment more efficiently than sb-paclitaxel, is indicated for the first-line 
treatment of locally advanced or metastatic non-small cell lung cancer, in combination with 
carboplatin, in subjects who are not candidates for curative surgery or radiation therapy 
(Desai, 2006). The median survival of all subjects with advanced NSCLC is 10-12 months 
(Carbone, 1995). The fraction of subjects who are alive one year after diagnosis has only 
increased slightly over the past decade (Carbone, 1995). Treating subjects with more than 
4 cycles of the same chemotherapy, or adding a third chemotherapy agent to the platinum-
based doublet has not improved overall survival (Carbone, 1995). Non-platinum-based 
regimens have been evaluated in several Phase II and Phase III clinical trials, showing 
similar survival rates to platinum based treatments (Rodriguez, 2000; Douillard, 2001; 
Kosmidis, 2002; Georgoulias, 2001, Alberola, 2003; Gridelli, 2003).  The EORTC-08975 
(Smit, 2003) randomized 483 subjects to three arms -- two cisplatin based regimens and one 
non-cisplatin based (paclitaxel/gemcitabine).  The response rates were similar (27.7% to 
36.6%) as was the median survival (between 6.7 months to 8.9 months), but progression free

survival was inferior in the non-platinum based regimen.  Other studies have reported 
somewhat worse results with non-platinum combinations, therefore platinum is still 
considered a preferred agent for combination chemotherapy in fit subjects with advanced 
NSCLC. 
Second line treatment for recurrent or progressive disease includes treatment with the 
chemotherapy agents docetaxel and pemetrexed, or treatment with an oral EGFR antagonist, 
erlotinib.  Docetaxel was approved for second line treatment in 2000 after a randomized trial 
demonstrated that docetaxel at 75 mg/m2 given every 3 weeks offered a clinically meaningful 
benefit to subjects with advanced NSCLC whose disease had relapsed or progressed after 
platinum-based chemotherapy with a response rate of approximately 7% (Fossella, 2000).  
Pemetrexed was approved for second line treatment based on a non-inferiority study as 
compared to docetaxel.  Treatment with pemetrexed resulted in clinically equivalent efficacy 
outcomes, but with significantly fewer side effects compared with docetaxel in the second-
line treatment of subjects with advanced NSCLC (Hanna, 2004).  With these findings 
pemetrexed has now become increasingly used in the second line setting, and recent clinical 
trials have extended its use in first line setting for the treatment of subjects with non-
squamous cell carcinoma NSCLC (Scagliotti, 2008).  A Phase III trial compared 
pemetrexed/cisplatin to gemcitabine/cisplatin.  This trial has demonstrated an improvement 
in overall survival over the combination cisplatin/gemcitabine in subjects with 
adenocarcinoma NSCLC (12.6 vs. 10.9 months) and in large cell NSCLC (10.4 vs. 6.7 
months) (Scagliotti, 2008).   
The decision to use pemetrexed depends on the histology of NSCLC. A recent review of two 
large pemetrexed based trials have concluded that although pemetrexed is well tolerated in 
squamous cell histology subjects, pemetrexed based regimens result in a shorter overall 
survival than non-pemetrexed based regimens in treatment of recurrent squamous cell 
NSCLC (Scagliotti, 2009).  With pemetrexed being used with increased frequency in the 
first-line setting for adenocarcinoma and limiting the use of pemetrexed to non-squamous 
cell histology, the need to develop improved second line agents has become increasingly 
important.  Currently, subjects with advanced NSCLC who have progressed after 2nd-line 
treatment have limited options.  Nivolumab has recently received FDA approval for use in 
the 2nd line setting for subjects with metastatic squamous cell carcinoma who have 
progressed on or after platinum-based chemotherapy based on the results of a Phase II trial, 
and data from the Phase III CheckMate-017 trial.    
Retrospective analysis using chemotherapy for 3rd line treatment show response rates of only 
2% and median survival of 4 months (Massarelli, 2003).   
Oral agents gefitinib and erlotinib are small molecule inhibitors of the EGFR tyrosine kinase 
activity, which have demonstrated clinical benefit after failure of first line chemotherapy 
(Fukuoka, 2003; Perez-Soler, 2004).  Erlotinib was approved in 2004 for the treatment of 
subjects with locally advanced or metastatic NSCLC after the failure of one or two prior 
chemotherapy regimens with a single agent response rate of 8.3 % and a median overall 
survival of 6.3 months (Shepherd, 2005).   To date it remains the only approved third line 
therapy for NSCLC.

2. SCLC: In contrast to the ferment and rapidly changing status of NSCLC, in which significant 
inroads have been made with targeted agents, the small cell lung cancer landscape has 
remained, like its name, disappointingly small and static.  Small cell lung cancer (SCLC) 
accounts for about 13% (Govindan, 2006) of all lung cancers and is strongly correlated with 
a history of smoking. It is an aggressive subtype of lung cancer associated with rapid growth, 
early spread to distant sites, and distinct paraneoplastic syndromes (Kazarian, 2011), 
including hypercalcemia, Eaton-Lambert syndrome, and syndrome of inappropriate diuretic 
hormone, that is treated with chemotherapy alone in the metastatic setting. The most 
commonly used classification is the Veterans Administration Lung Study Group (VALG) 
staging system, in which the disease is subdivided into limited stage (LS) and extensive stage 
(ES) (Allen, 2008; Dowell, 2010; Drivsholm, 1999). Without treatment extensive stage small 
cell lung cancer (ES-SCLC), representing approximately two-thirds of all cases (LS-SCLC 
comprises the other one-third), is rapidly and invariably fatal within two to four months 
(Pelayo, 2009). With combination chemotherapy, the cornerstone of management (DeVore, 
1996) in subjects without localized symptoms (i.e. superior vena cava syndrome, lobar 
obstruction, or painful bone metastases), responses are dramatic but sadly short-lived: SCLC 
inevitably relapses (Hann, 2009) and relapse is associated with a median OS often <6 months 
(Davies, 2004), a survival rate which has scarcely improved over the last 40 years (Shepherd, 
2007).  
The current standard of first-line care for ES-SCLC is platinum based with a combination of 
cisplatin and etoposide (or cisplatin-irinotecan or cisplatin-topotecan) with or without 
concurrent radiation therapy, followed in general by topotecan, the sole agent with FDA 
approval specifically for the second line setting in platinum-sensitive disease and relapsed 
disease at least 45 days from the end of first-line chemotherapy. (Chan, 2013). A standard 
third line treatment is lacking although single agent paclitaxel, irinotecan, gemcitabine and 
vinorelbine are commonly tried in subjects with acceptable performance status. With relapse 
the prognosis is poor, with about a 20% to 30% response, and a median survival of weeks to 
months (Allen, 2008; Dowell, 2010; Drivsholm, 1999).  
In the case of resistant or refractory relapse classified as a progression free survival of greater 
<3 months or progression during treatment, rechallenge is not warranted whereas it is 
warranted with sensitive relapse classified as a progression free survival of greater >3 months 
(Ardizzoni, 2014) on the basis of a meta analysis by Garassino et al in which 30% of subjects 
experienced clinical benefit (i.e. stable disease + partial response) with rechallenge 
chemotherapy (Garassino, 2011).   
The ability to improve on these clinical benefit rates with an agent like RRx-001 that may 
predispose to successful platinum rechallenge represents a breakout opportunity to change 
the rules of the ‘game’ from a treatment paradigm of ‘one (or hopefully more) and done’ to 
‘if at first you succeed try and try again’ thereby permanently altering a therapeutic landscape 
that for the last four decades has remained largely stagnant.  
3. HGNEC: Unlike lung cancer, which is the second most common tumor type and the leading 
cause of cancer-related deaths among both men and women in the world (Abbasi, 2011), 
extrapulmonary high-grade neuroendocrine carcinomas (HGNECs) (Shia, 2008) are rare, 
aggressive tumors, with a poor prognosis, biologically similar to small cell lung cancer, that

most commonly develop in the gastrointestinal (GI) and the genitourinary (GU) tracts 
(Strosberg, 2010). Since cisplatin-based regimens, especially the cisplatin and etoposide 
regimen, are the most studied and widely used in metastatic small-cell lung cancer, they have 
also been investigated in metastatic NECAs of the GI tract. The first such study by Moertel et 
al reported a response rate of 67% with response duration of 8 months and a median survival 
of 19 months (Moertel, 1991). 
A subsequent study reported a response rate of 42% with response duration of 9 months and 
a median survival of 15 months (Mitry, 1999). 
On the basis of these clinical trials, the combination of cisplatin and etoposide is 
recommended as standard first-line therapy; carboplatin and irinotecan are offered as 
substitutes for cisplatin and etoposide, respectively.  However, the optimal duration of 
chemotherapy is unknown and unclear, as is the question of whether to continue treatment 
beyond 4 cycles. While there is no data for a standard regimen in second line, retreatment 
with platinum and etoposide is an option especially if an initial response was seen and 
relapse occurred more than three months afterwards. 
4. Gynecologic Cancers: Epithelial ovarian cancer or EOC (70% of all ovarian cancers with 
stromal and germ cell tumors comprising the rest) is the fifth most lethal gynecologic 
malignancy and the leading cause of cancer deaths in women in industrialized countries 
(Jemal, 2005). Since early ovarian cancer causes minimal to no symptoms, 75% of subjects 
present with advanced disease (stage III – IV), where the five-year survival rate falls below 
25% (Rien, 2011). Malignant Mixed Mullerian Tumor (MMMT) of the ovary or uterus are 
dedifferentiated (metaplastic) epithelial tumors comprised of carcinomatous and sarcomatous 
elements arising from a single malignant clone. MMMT is also referred to as 
Carcinosarcoma and accounts for between 2 to 7.5 percent of ovarian carcinomas but is 
perhaps the most lethal of all subtypes (Seidman, 2003). These tumors tend to present in 
more advanced stages and are often large, necrotic and/or hemorrhagic. MMMT generally 
progresses rapidly and responds briefly to platinum-based chemotherapy, which portends a 
poor prognosis (Silasi, 2008), (Mano, 2007). Uterine MMMTs are generally excluded from 
endometrial clinical trials because of the belief that they are of dedifferentiated epithelial 
origin with a much more aggressive, sarcoma-like clinical behavior (Vaidya, 2006).  For this 
reason, we are including them in this cohort with their more closely related ovarian MMMT 
cousins.  
Standard initial treatment involves tumor debulking and platinum-based chemotherapy with a 
taxane derivative to which the response is high (approximately 70%), however, 60–80% will 
relapse under two years with a platinum-resistant metastatic disease that is uniformly fatal 
(Gubbels, 2010). The Gynecologic Oncology Group (GOG) adopted the definition of 
sensitivity to chemotherapy (or sensitivity to platinum) in EOC based on the interval between 
the last dose of platinum and the development of resistance (Harter 2006) (Figure 1). 
In general, progression or stable disease during first-line treatment or relapse within 1 month 
is characterized as 'platinum-refractory'. Subjects who respond to primary treatment and 
relapse within 6 months are considered 'platinum-resistant', and subjects who relapse more 
than 6 months after completion of initial therapy are characterized as 'platinum-sensitive'. 
The longer the platinum free interval (PFI) the better the chances for benefit with platinum

re-challenge. This is especially the case for PFI longer than 12 months. Subjects that relapse 
6-12 months after the end of their initial regimen, and who are usually classified as so-called 
'partially sensitive', tend to be less responsive (Pisano, 2009).

Platinum resistance definition by Gynecologic Oncology Group (GOG) 
Platinum sensitivity is classified as resistant, partially sensitive, or sensitive, according to the 
time elapsed since finishing first-line treatment. Probability of re-treatment response is shown. 
 
 
In the setting of platinum resistant disease, a poor prognosis population with an OS <12 months, 
no universal standard for treatment exists; single agent therapy with paclitaxel, topotecan, 
pegylated liposomal doxorubicin (PLD) and gemcitabine is generally recommended in second 
line based on some evidence of activity in Phase III trials, with overall response rates <15% and 
a median PFS of 3–4 months. (Gordon, 2004; Markman, 2006) In contrast with platin-sensitive 
recurrences, combination chemotherapy has been shown to increase toxicity without benefit 
(Ledermann, 2013). The possible exception is bevacizumab, which in the 2012 AURELIA trial, 
significantly improved the PFS in combination with an investigator’s choice of pegylated 
liposomal doxorubicin, weekly paclitaxel, or topotecan but not the overall survival. (Pujade-
Lauraine, 2014). 
RRx-001 is a small molecule administered by i.v. that selectively and with great affinity binds to 
hemoglobin and free sulfhydryl groups such as reduced glutathione present in red blood cells. 
RRx-001 modified, oxidatively stressed red blood cells exhibit conformational and biochemical 
alterations under hypoxia, which collectively may lead to adhesion to the tumor vascular 
endothelium, entrapment in the microvasculature, and engulfment by tumor associated 
macrophages (TAMs), which undergo M2 to M1 polarization. Preclinical and Phase 1 data 
suggests that RRx-001 altered DNA methylation of genes and cancer pathways restores 
sensitivity to previously failed therapies resulting in a prolonged overall survival. On this basis, 
reintroduction of platinum doublet-based therapies is mandated on progression. In addition, 
immunohistochemistry of tumor biopsies from subjects on the QUADRUPLE THREAT trial

have revealed an influx of CD8 expressing tumor-infiltrating lymphocytes, confirming that RRx-
001 has immunotherapeutic properties (Brzezniak, 2016). 
Before co-infusion with blood, the primary adverse event related to RRx-001 was pain during 
infusion that manifested together with local venodilation (Reid, 2015), presumably due to the 
displacement of nitric oxide (NO) from its binding site on the beta Cys 93 residue on 
hemoglobin. This infusional pain that was subject to considerable inter-subject variability 
resolved within seconds to minutes after administration was stopped. In the same way that 
capsaicin evokes a sensation of burning without producing tissue damage, RRx-001, likely 
through the intermediary of nitric oxide, a well-known algetic stimulus on intravascular 
application in humans, activated nociceptors in the venous endothelium to produce pain.  
Subjects enrolled and treated on the QUADRUPLE THREAT study with RRx-001 blood mix 
has been well tolerated without any significant drug related toxicity reported.   
RRx-001 has demonstrated the capacity to reverse resistance to first and second line 
chemotherapy in selected subjects treated on the Phase I trial (Reid, 2014). Reintroduction of 
first-line platinum doublet-based therapies after treatment with RRx-001, therefore, potentially 
represents an important and highly desirable strategy to improve clinical outcomes and prolong 
survival by significantly impacting the natural histories of SCC, NSCLC, ovarian and HGNEC. 
3.2 RRx-001 as a Tumor-Associated Macrophage Targeting Agent with 
Tumor Sensitizing Properties 
RRx-001 (previously known as ABDNAZ) is a TAM-targeting agent with epigenetic and tumor-
sensitizing properties that has been investigated in a completed Phase I study at UCSD and Sarah 
Cannon Research Institute (SCRI) (Reid, 2015) and an ongoing randomized Phase 2 study vs. 
regorafenib in 3rd and 4th line colorectal cancer.  
3.3 Clinical Experience with RRx-001 
To date, RRx-001 has been studied in a single Phase 1 clinical trial (Protocol RRx001-11-01, 
Reid, 2015).  The study design was standard ‘3+3’ dose escalation cohorts based on a modified 
Fibonacci scheme.  The primary endpoint was safety and pharmacokinetics with the objective of 
defining a maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D). 
RRx-001 was administered to subjects intravenously through a peripheral line on a weekly and 
twice-weekly schedule. 
The open-label, Phase I dose-escalating clinical trial in heavily pretreated subjects with 
refractory metastatic solid tumors investigated the safety and tolerability of RRx-001 when 
administered as monotherapy. Key inclusion criteria were histologically proven solid tumor for 
which no satisfactory therapy was available or had failed, adequate organ and hematologic 
function, ECOG performance status of ≤2 and life expectancy of at least 3 months. Key 
exclusion criteria included previous cancer therapy within 42 days of baseline visit. 26 subjects 
were enrolled and 25 subjects were treated. The treatment was continued until disease 
progression, intolerable toxicity, or subject withdrawal of consent.

RRx-001 was tolerated at all doses from 10-83 mg/m2 i.v. and a maximum tolerated dose was not 
reached. Twenty-five subjects received the study drug and are therefore considered evaluable for 
analysis of safety. All 25 subjects experienced at least one adverse event. Events considered 
definitely related to protocol therapy were reported in 23 of 25 subjects (92%). Inflammation 
and/or burning along the course of the injected vein were the most common AEs. Two events of 
Grade 3, infusion site pain and anxiety related to infusion site pain, were reasonably possible or 
definitely related to study drug in the opinion of the Investigator. Three subjects experienced 
adverse events or other problems leading to premature termination from the study and before an 
assessment of activity could be determined. Subject 001-002 withdrew consent due to infusion 
site reaction, 002-005 died on study due an SAE arising from a preexisting infection and 002-014 
withdrew due to an AE (bowel obstruction) that was considered to be unlikely related to RRx-
001 administration. In one subject, Grade 3 anxiety was observed associated with the localized 
pain on infusion. However, this event was not considered dose limiting, as it was transitory, and 
promptly disappeared after the infusion was discontinued. Other Grade 1 to Grade 2 related 
toxicities included infusion site tenderness, vein hardening, vein occlusion, skin discoloration 
over the site of injection, chest discomfort, cough, dyspnea and mouth tingling but the relative 
contributions of RRx-001 and malignant disease in the etiology of these toxicities is not known.  
No specific laboratory abnormalities were attributed RRx-001; any abnormalities appeared to be 
more indicative of the underlying systemic disease rather than RRx-001. No RRx-001 related 
adverse effects on the major physiological systems (cardiovascular, respiratory, hepatic, renal 
and central nervous systems) occurred in any subject. 
In contrast to standard IV administration, which is lengthy (up to 6 hours), time consuming and 
acutely painful, the RRx-001 blood mix is rapidly administered in under an hour and painless; 
hence the reason that all of the RRx-001 protocols have been converted to this method of 
administration.  
Solutions of RRx-001 for Injection were previously tested for hemolytic potential:  
Test formulations of 0 (vehicle), 0.5, 1.0, or 2.0 mg/mL RRx-001 were tested (1:1) with human 
whole blood and plasma. Hemolysis was evaluated by determining the amount of hemoglobin in 
the supernatant following incubation. Plasma compatibility was determined macroscopically. 
Formulations of 0.5, 1.0, and 2.0 mg/mL were prepared by mixing RRx-001 powder with the 
vehicle (3% DMA, 6% PEG 400 NF, and sterile WFI USP). Osmolality values were 618, 612, 
and 614 mOsm/kg for the 0.5, 1.0, and 2.0 mg/mL formulations, respectively, compared with the 
control value of 606 mOsm/kg. RRx-001 at concentrations of 0.5, 1.0, or 2.0 mg/mL or vehicle 
alone did not cause hemolysis or macroscopic changes in plasma.  
A time course following dilution of human whole blood (5 parts) to RRx-001 infusion solution 
(1 part) was followed over two hours. CBC parameters were collected at 1, 5, 15, 60 and 120 
min. At this dilution and over this time period, only mild changes in cell size were noted. No 
evidence of clotting or hemolysis was seen.   
In the Phase I study, antineoplastic activity was detected in several solid tumor types: non-small 
cell lung cancer, colorectal cancer, ovarian cancer, hepatocellular cancer, pancreatic cancer and 
head and neck cancer. One objective partial response was observed.  There was no obvious

correlation between the antitumor activity and the dose level. After single agent therapy with 
RRx-001, four subjects became responsive to previously failed FOLFIRI, as shown by changes 
in CEA and by imaging. 
 
A further three subjects appeared to respond favorably to subsequent chemotherapy and radiation 
post RRx-001.  
3.3.1 Safety 
Twenty-five subjects were treated at 6 dose levels of 10 (n=6), 16.7 (n=3), 24.6 (n=3), 33 (n=4), 
55 (n=3), and 83 (n=6) mg/m2. RRx-001 was generally well tolerated. Adverse events were 
mostly Grades 1 and 2, with one Grade 3 infusion site pain and one Grade 3 anxiety. Pain at the 
site of injection was most common (84%), mostly Grades 1 and 2, and related to study drug 
(Table 1). RRx-001 was initially infused intravenously weekly over 20 minutes. With increasing 
doses of RRx-001, infusion site pain required increasing the infusion time up to 8 hours and 
splitting the total dose and administering RRx-001 twice-weekly at the highest dose of 
83 mg/m2.  No dose-limiting toxicities (Grade 3 infusion site pain was not considered a DLT) 
were observed in any cohort, and therefore the maximum tolerated dose was not reached. 
However, due to the infusion site pain that could be mitigated by slowing the infusion rate, 
83 mg/m2 was considered to be the maximum feasible dose when delivered over up to 8 hours.

There were 12 serious adverse events (SAEs) reported in 10 subjects, all of which were 
considered unrelated to study drug.  The SAE terms were 1) seizures secondary to brain mets; 
2) hypercalcemia; 3) cerebral bleed; 4) increased somnolence; 5) atelectatic changes right lung 
base; 6) bilrubinemia; 7) klebsiella septicemia; 8), upper gastrointestinal bleed; 9) pleural 
effusion (two SAEs in the same subject); 10) bowel obstruction; and 11) dehydration. Overall, 
the types of serious AEs reported among this study population were consistent with the severity 
of illness and underlying disease. No ECG effects or clinically relevant RRx-001-related changes 
in vital signs or laboratory values were seen in the study.  
There were 4 deaths on study or within 30 days of last dose of study drug, all considered 
unrelated to RRx-001, and related to the subjects’ underlying malignancy. 
RRx-001 was administered through a peripheral vein. 84% of subjects across the 6 cohorts 
experienced a prominent and transient, dose-dependent forearm vasodilation and transient mild 
to moderate pain that was ameliorated with slowing of the infusion time, stopping and restarting 
the infusion at a slower rate, and concomitant administration of analgesics (short-acting opioids), 
benzodiazepines or anti-inflammatory medications such as corticosteroids as needed. 
In particular, premedication treatment with corticosteroids and ibuprofen at the day of dosing 
was found to be effective. Premedication with corticosteroids is required at every RRx-001 
administration when administering by direct IV infusion.   
Several subjects in the highest dose cohort (83 mg/m2), complained of moderately severe 
injection pain, that was inadequately addressed with adjunctive opioid analgesics and have 
received a reduced total dose or a split dosing schedule (twice-weekly). Overall, higher doses 
tend to result in a concomitant escalation in pain, which has become more severe in the later 
cohorts. At present, 83 mg/m2 is the maximum feasible dose using the current infusion rates. 
Most subjects recovered from the injection site pain and vasodilation within minutes of the 
infusion being stopped or slowed down and without sequelae; four subjects temporarily 
developed a non-tender, non-erythematous cord-like induration over the vein of injection, which 
resolved spontaneously within a few weeks. Duplex ultrasound was negative for venous 
thrombosis and in the absence of warmth, swelling, redness or tenderness, the diagnosis was 
more suggestive of focal venous dilation than superficial phlebitis.  Initially, RRx-001 was 
administered through a central IV line. However, based on complaints from one subject in the 
first cohort of an unpleasant nasopharyngeal burning sensation, which led to his (voluntary) 
discontinuation from the study, IV administration was moved to the antecubital or forearm area. 
In summary, other than localized venous dilation and pain on infusion, RRx-001 was very well 
tolerated.  The pain was dose related and resulted in attempts to slow the infusion and split the 
dose between two days within a week.  The maximum feasible dose appears to be 83 mg/m2 at 
the present time and under the present infusion conditions.  
3.3.2 Pharmacokinetics 
As part of the Phase I protocol, the pharmacokinetics of RRx-001 was investigated.  PK samples 
were taken at Day 1 and Day 50 within 15 min predose, 15 min after the start of the infusion, at 
the end of the infusion (0±1 min) then at 15±2 and 30±5 min after the end of infusion followed 
by 1, 2, 3, 4.5, 6 and 24 hours ±5 min post infusion. The 24 hour sample was taken for Day 1

only. As part of change in cycle duration from 4 weeks to 2 weeks in Amendment 1.3, Day 50 
samples were redefined as Day 22 and the requirement for a 6 h sample on Day 22 was removed. 
Based on the available data, in Amendment 1.4, the Day 1 the 4.5 and 6 h as well as the Day 22 
samples were removed.  
The following parameters were calculated for each subject: Cmax, AUCinf, and half-life and is 
shown in Table 2. Half-life did not vary greatly across dose levels or between Day 1 and 
Day 22/50 samples and was found to be 0.46 h. The calculated average Cmax and AUCinf for 
both Day 1 and Day 22/50 for each cohort, was found to be dose dependent with the exception of 
the highest dose cohort. Figure 2 shows the plots of average AUCinf (left) and Cmax (right) for 
Day 1 and Day 22/50 against dose. These data suggest that analysis of RRx-001-GSH is 
indicative of exposure to RRx-001 for the range 10 to 55 mg/m2. However, the pharmacokinetics 
of RRx-001-GSH do not correlate well with the pharmacodynamics of RRx-001. Accordingly no 
justification for dosing decisions based upon PK information of the glutathione adduct can be 
made.

An overview of relevant nonclinical information is presented below. 
3.3.3 Preclinical Studies of RRx-001 
RRx-001 is a de-energized analog of the explosive, TNAZ, the widely-used replacement for 
TNT, with a closed strained ring structural backbone called a dinitroazetidine, developed as an 
anticancer agent. 
Preclinical and clinical studies support the rationale for the clinical development of RRx-001 in 
the setting of metastatic refractory cancer both as monotherapy and in combination with standard 
cytotoxic chemotherapy. 
RRx-001 is a nitrogen oxide donor. In hamsters infused with RRx-001 through a central vein at a 
dose of 5 mg/kg vs. hamsters infused with saline as vehicle controls, significantly increased 
levels of exhaled nitric oxide in breath condensate were measured in the treated cohort during the 
infusion; these levels returned rapidly to baseline almost immediately after cessation of the 
infusion. 
With infusion into the antecubital veins, the nitric oxide dissipation effect during infusion is 
clearly visible as a network of dilated, palpable superficial veins that travel up the forearm 
proximally in the clinical trial subjects, confined to and persisting only for a distance of 8-10 
inches from the site of infusion. The discomfort of the infusion in the forearm varied greatly 
from subject to subject and did not appear to correspond to the amount of visible dilation. 
The anticancer mechanism of action is related to modification of the intracellular milieu of the 
red blood cell and repolarization of tumor associated macrophages. RRx-001 covalently binds to 
the beta Cysteine 93 residue on hemoglobin, which significantly upregulates the nitrite reductase 
activity of hemoglobin, catalyzing the conversion of the endogenous anion nitrite to nitric oxide 
under hypoxic conditions. This overproduction of NO under hypoxic conditions oxidizes the red 
blood cell, leading to the expression of phosphatidylserine (PS) and vascular cell adhesion 
molecules at the RBC surface. RBC adhesion to the tumor endothelial cells sequestrates the 
RBCs and occludes the tumor microvasculature. Macrophages, which engulf and degrade the 
adherent and PS-expressing RRx-001 RBCs, extravasate into the extravascular stroma

(Figure 3), as demonstrated by the intracellular lipid accumulation and, consequently, foam cell 
formation or vacuolation seen on tumor biopsies (Figure 4). Engulfment of the RBCs induces 
TAM repolarization to antitumor M1 macrophages that secrete proinflammatory cytokines and 
produce free radicals (Figure 5). The secreted cytokines recruit more immune cells and the 
increased production of reactive oxygen and nitrogen species inhibit activity of the 
hypomethylating enzyme DNMT1 involved in epigenetic processes.

3.3.4 Preclinical Studies of RRx-001 (continued): Chemoprotection with Cisplatin 
The chemoprotective effect of RRx-001 was studied on cisplatin-induced nephro-, myelo- and 
genotoxicity in BALB/c mice. The mice were divided into three groups: (1) no treatment, 
(2) vehicle and cisplatin only, and (3) RRx-001 and cisplatin. RRx-001 treatment (5 mg/kg every 
other day for three days) was initiated 3 days prior to cisplatin administration. Renal dysfunction 
was evaluated biochemically by measuring the concentration of blood urea nitrogen (BUN) and 
serum creatinine. Genotoxicity was evaluated by metaphase spreads from whole bone marrow 
cells. Myelotoxicity was evaluated with measurement of serum hemoglobin, leukocyte and 
platelet concentrations.  
Cisplatin significantly elevated the levels of blood urea nitrogen, serum creatinine, and the 
kidney to body weight ratio, but pretreatment with RRx-001 significantly attenuated the 
cisplatin-induced nephrotoxicity. After administration of cisplatin, the frequency of 
chromosomal abnormalities distinctly increased. However, in mice pretreated with RRx-001, 
Consistent improvement in chromosome spreading with lower frequencies of broken metaphases 
was obtained in RRx-001-pretreated mice compared with mice injected with only cisplatin, as 
seen in the figure below.

The results suggest that RRx-001 has a protective effect against cisplatin-induced nephro-, 
myelo- and genotoxicity. 
3.4 Rationale 
Survival of SCC, NSCLC, resistant/refractory EOC/MMMT and HGNEC cancer subjects 
remains poor, and new effective and well-tolerated therapeutics for chemorefractory subjects are 
urgently needed. We propose a Phase 2 study of RRx-001 administered at a dose of 4 mg once 
weekly in SCC, NSCLC, EOC/MMMT and HGNEC subjects until progression followed by re-
administration of a platinum based regimen specific to the four tumor types outlined in the 
methodology section. To be eligible for this trial, subjects must have received platinum doublet 
therapy as standard therapy for advanced disease and now have progressive disease. 
This study design is based upon clinical experience of subjects who were treated with RRx-001 
monotherapy in the phase I setting, followed by the off-trial re-treatment with therapies that they 
may have previously failed. Two subjects, both with colorectal cancer (CRC), were noted to 
have responses both in tumor burden and CEA upon re-challenge with FOLFIRI, which they had 
each previously failed. The first subject had a 7-month duration of response. The second subject 
was restarted on FOLFIRI in 7/2013 and responded to this therapy (Reid, 2014). Two additional 
subjects, one with colorectal cancer (CRC) and one with lung cancer, both achieved prolonged 
stable responses after treatment with RRx-001 and re-challenge with a previously failed therapy: 
sorafenib and gemcitabine, respectively.  
Early data analysis in the QUADRUPLE THREAT trial demonstrated 8/13 (61%) of patients had 
been newly sensitized to platinum doublets, indicative of reversal of chemoresistance. Given the 
limited choices of subjects with advanced thoracic malignancies, this reversal of resistance, 
which in theory ‘primes’ tumors to respond subsequent chemotherapy may allow previous 
responders to derive benefit from retreatment of the same chemotherapy after previous exposure 
to RRx-001. In addition, immunohistochemical staining of HC of tumor biopsies from two 
subjects on the TRIPLE THREAT trial revealed the infiltration of cytotoxic CD3+ CD8+ 
lymphocytes.

4.4.2 Secondary Endpoints 
1. Disease Control Rates (DCR): The percentage of patients who have achieved complete 
response, partial response and stable disease (as per RECIST v1.1). 
2. Progression free survival (PFS): the time from enrollment to the time of the first 
radiographic documentation of objective progression as defined by RECIST v1.1 or death 
from any cause. 
3. Toxicity: Rate of Grade 3 and Grade 4 hematologic and non-hematologic toxicities of 
reintroduced platinum based chemotherapy. 
4. The transition probability between disease progression and disease amelioration 
attributable to sensitization/resensitization and the mean sojourn time. 
4.4.3 Exploratory Endpoints 
1. Circulating Tumor Cells: 
Peripheral blood will be collected to correlate changes in circulating tumor cells with 
clinical response. CTCs will be assessed using ferrofluidic enrichment and multi-
parameter flow cytometric detection. CTCs are identified by positive expression of 
epithelial markers and a viability marker and negative expression of hematopoietic 
markers. 
2. Circulating Endothelial Cells (CEP and CEC): 
Circulating endothelial progenitor cells (CEP) and mature circulating endothelial cells 
(CEC) will be assessed by multiparameter flow cytometry. Cells will be analyzed for 
forward and side scatter, and cells expressing hematopoietic markers will be excluded.  
Endothelial cells will be identified using co-expression of markers, such as CD31 and 
CD146 for CEC, and CD31 and CD133 for CEP. The cell populations will also be 
analyzed for viability using scatter profiles and a vital stain, such as Hoechst 33258. 
Percentages of stained cells will be determined and compared with appropriate negative 
controls. Multi-parameter flow analysis will be performed with a Miltenyi Quant 
equipped with FlowJo software, using a minimum of 500,000 events per analysis. 
3. Immune Subsets: 
The immune infiltrate will be analyzed in tumor biopsies obtained pre- and post-therapy. 
The tissue will be dissociated into single cells and assessed by multiparameter flow 
cytometry for immune subsets. The immune populations analyzed will be dependent on 
the number and viability of infiltrating immune cells.  Subsets analyzed may include 
regulatory T cells (Tregs), myeloid-derived suppressor cells (MDSC), effector and 
exhausted CD8+ T-cells, and type II polarized macrophages (TAMs). As sample permits, 
assessment will include functional markers, i.e., PD-1, PD-L1, Tim-3, CTLA-4 and 
CD40. Peripheral blood mononuclear cells (PBMC) will be assessed using 
multiparameter flow cytometry for immune subsets including but not necessarily limited 
to Tregs, MDSC, effector and exhausted CD8+ T-cells.  Assessment will include 
functional markers, i.e., PD-1, Tim-3, CTLA-4 and/or CD40.

4. Epigenetic markers e.g., Protein Hyperacetylation and gene methylation:  
Protein hyperacetylation pre- and post-therapy will be assessed in peripheral blood 
mononuclear cells (PBMC) using multiparameter flow cytometry. Gene acetylation and 
methylation will be carried out by PCR and IHC techniques. The impact of RRx-001 on 
the epigenetic status of genes that are closely correlated to resistance to platinum therapy 
will be studied.  
5. Status of tumor suppressors such as p53, pre and post RRx-001: 
Expression and mutational status of tumor suppressors such as p53, p21 will be studied 
by PCR and IHC techniques to see if silenced genes can be reactivated.   
6. TGF-beta and its receptor and fibrosis status:  
Radiotherapy has been shown to induce increased expression of both TGF-beta and its 
receptor, which is associated with an increase in fibrosis. Due to the pro-oxidant effect of 
RRx-001 in tumors, it is hypothesized that a similar effect may occur with RRx-001. Pre 
and post biopsy samples will be used to investigate this effect.  
7. MicroRNAs (miRNAs) relating to gene expression:  
MicroRNAs (miRNAs) are short noncoding RNAs that influence gene expression. 
Increased miRNA levels downregulate genes; conversely, decreased miRNA levels may 
result in upregulated genes. RRx-001 has been shown to decrease a specific set of 
miRNAs in the tumor that result in upregulation of type III hypersensitivity genes. 
Profiling of these perturbed miRNAs in the context of RRx-001 treatment may help to 
predict drug responses. The PAXgene blood tubes are provided to isolate miRNA and 
total RNA for analysis. 
8. The relative macrophage density:  
TAMs will be immunohistochemically labeled using a monoclonal (CD68) antibody in 
biopsy specimens from patients. CD68-positive cells will be counted with the aid of a 
microscope and expressed as TAMs/mm2. TAMs will be quantified by systematically 
screening the entire cancer area and by counting at the hot spot in a cancer area where 
macrophages accumulated at highest density in the specimens. The densities of these 
cells will scored as +, low; ++, moderate; and +++, high.

5 STUDY DESIGN 
5.1 Description of the Study 
The study is designed to explore the potential tumor associated macrophage (TAM)-targeting 
agent RRx-001 to sensitize patients who previously received and now have failed a platinum 
based regimen.  
RRx-001 is administered with autologous blood once weekly followed by or in combination with 
reintroduction of platinum-based therapy according to the treatment schedule illustrated in 
Section 1.1 Treatment Schemas [SCC, EOC, NET, NSCLC] ). 
As of Amendment 10, an investigator’s choice control arm has been added to small cell 
carcinoma and ovarian enrolled patients, randomized 2:1 to 1 of 2 Arms. The investigational 
ARM 1 will enroll an additional 26 patients, with the ‘investigators choice’ control arm enrolling 
13 patients total, per patient group.  
In addition, in neuroendocrine and NSCLC cohorts, after up to 6 cycles of the reintroduced 
platinum doublet, patients with stable disease or better (>SD) start on maintenance RRx-001 
administered weekly (QW) until progression.  
5.1.1 Toxicity  
Toxicity will be graded according to the National Cancer Institute (NCI) Common Toxicity 
Criteria for Adverse Events (CTCAE) version 5.0.  
Serious and unexpected toxicity is defined as ANY Grade 3 or higher toxicity considered by 
the investigator to be possibly, probably or definitely related to the study drug, RRx-001, or to its 
potentiation of protocol defined therapy toxicity, occurring after the initial dose of RRx-001 until 
up to 30 days after discontinuation of protocol defined therapy. The following exceptions are not 
considered serious and unexpected toxicity related to RRx-001 or protocol defined therapy: 
• Grade 3 or 4 anemia, or neutropenia that resolve to ≤Grade 2 within 10 days.  Patients 
should have repeat labs within 10 days to document resolution. 
• Grade 3 or 4 thrombocytopenia without clinically significant bleeding that resolves to 
≤Grade 2 within 10 days.  Patients should have repeat labs within 10 days to document 
resolution. 
• Grade 3 or 4 leukopenia/lymphopenia without clinically significant consequences 
(i.e., infection). 
• Grade 3 nausea, vomiting or diarrhea with maximal medical support that resolves to 
≤Grade 2 within 72 hours. 
 
If 5 patients develop serious and unexpected toxicity in a particular RRx-001 cohort, which is 
thought to be directly or indirectly related to RRx-001, then enrollment in that particular cohort 
will stop. Management and dosing modifications are outlined in Section 6.2.6.

6.2.2 RRx-001 Dose, Procedure and Dose Schedule 
Treatment will be administered on an outpatient basis. Patients will receive 4 mg of RRx-001, 
premixed with the patient’s blood prior to reinfusion, in the schedule described in the Schedule 
of Assessments.  
The administration procedure of RRx-001 incorporates the use of an in-line filter ‘device’ as an 
added patient safety element; though likely unnecessary, given the patient’s own blood is being 
drawn into a syringe containing anticoagulant, where the study drug (RRx-001) is subsequently 
transferred to mix with the blood, followed by the treated blood being reinfused back into the 
patient, within approximately 15 minutes from start of blood draw, all inside a closed sterile 
assembly.  
The filter ‘device’ is a clinical use in-line blood filter and is part of an FDA approved Neonatal 
Syringe Set that is used to deliver small aliquots of whole blood. Modification was made for our 
use by the manufacturer, both to the tubing length (adding approximately 3”) and tubing ends 
(changing the previously female luer connector to a male luer connector on 1 end, and a 
removing an IV bag spike and replacing it with a male luer connector on the opposite end), thus 
making this technically ‘off label’ use.  
Appropriate in-use studies have been conducted with this filter ‘device’ and these results along 
with the following device labeling: ‘CAUTION—Investigational device for use with RRx-001. 
Limited by Federal law to investigational use under IND 107,674’ have been shared with the 
FDA by way of an information amendment submission, dated December 14, 2017. 
A description of the pretreatment regimen is further outlined in Table 3 below. Appropriate dose 
modifications are described in Section 6.2.6.

The patient's identification must be verified by two people prior to starting the blood draw and 
infusion process.  Ensure that the RRx-001 and anticoagulant doses, both provided from 
pharmacy, are for the correct patient (using patient identifiers noted on labeling); that the RRx-
001 and anticoagulant are mixed with the patient's autologous blood; and that the mixture is re-
infused back to the correct patient.  DO NOT proceed with administration if any discrepancies 
are noted.  
Proper Handling: 
The methodology for administering the RRx-001 dose by premixing with the patient’s blood is 
based on procedures used in blood product transfusions.  Standard procedures for avoiding

hemolysis will be followed. These include the use of large gauge IV needles (19g or larger 
preferred) and slow consistent rate during blood draw to avoid undue mechanical shear stress to 
red blood cells.  
Whenever blood is present during the administration procedure, handle with care and do not 
shake.  Avoid excessive temperatures, (both high and low temperatures can cause hemolysis). 
Avoid conditions that create high turbulence or trauma to the red blood cells.  
Anticoagulant & RRx-001 Doses Prepared by the Pharmacy: 
The Anticoagulant and RRx-001 doses will be prepared by the pharmacy for the clinic, where the 
patient administration procedure takes place. For details of the pharmacy procedure, please refer 
to the latest version of the pharmacy manual. 
Administration Procedure in the Clinic: 
The RRx-001 and anticoagulant doses should be properly labeled per institutional standards and 
in accordance with the latest pharmacy manual guidelines.   
Administration procedure steps should be followed carefully and can be found in the latest 
version of the ‘Blood Administration Best Practices & Guidelines for IV Infusion of RRx-001 + 
Blood Mix’.  Safety guidelines are based on procedures used in blood product transfusions.  It is 
important each step is followed in the order outlined in the guide to maintain sterility at all 
times. 
6.2.3 Protocol Defined Therapies 
Standard of care protocol defined therapies will be administered per institutional standard of care 
and in accordance with the United States Package Insert (USPI) approved by the US FDA. Any 
patient with a history of toxicity that required permanent discontinuation of any of the 
chemotherapy agents is ineligible.

Treatment interruption and/or dose reduction may be needed to manage suspected adverse drug 
reactions in line with standard treatment practice. Refer to the United States Package Insert 
(USPI) for dose interruption and modification instructions. Patients who previously required 
dose reduction selected treatment in the first line setting may start treatment at a reduction of the 
standard dosing, at the discretion of the investigator.    
6.2.4 Other Considerations 
The hydration for cisplatin should occur pre and post infusion and additionally, supportive 
diuretics (i.e., mannitol) may be used per investigator discretion. For those treatments considered 
highly emetogenic anti-nausea regimens will be followed per standard of care.  Hematopoietic 
growth factors may be used per standard of care. 
Hematopoietic growth factors (i.e., G- or GM-CSF).  
• The use of filgrastrim (neupogen) will be allowed for treatment of Grade 3 or 4 neutropenia 
or febrile neutropenia. Filgrastrim (neupogen) must be discontinued at least 48 h prior to 
initiation of the next dose of chemotherapy and prior to the initiation of the next cycle of 
therapy.  
• 
The use of pegfilgrastim (neulasta) will be allowed as secondary prophylaxis if there was 
evidence of Grade 3 or 4 neutropenia on a previous cycle.  
 
6.2.5 Criteria for Continuing Treatment 
Patients will be evaluated during the treatment period to determine if continued treatment is 
appropriate. If, at any time during treatment the criteria are not met, treatment will be held or the 
dose adjusted per protocol and/or per the United States Package Insert (USPI) for treatment 
parameters. 
6.2.6 Dosing Delays/Dosing Modifications: RRx-001 
Mild or moderate infusion-related reactions were reported as the most common infusion reaction 
with RRx-001 when infused directly, and these responded to a reduction in the rate of injection.  
Although mild reactions were observed when RRx-001 was infused using the Blood-Mix dosing 
procedure, if a reduction in dose is required or desired, for any reason, whether or not toxicity is 
present, it is permissible to decrease the dose from 4 mg to 2 mg.  Dose modification or drug 
discontinuation for toxicity may take place at the discretion of the Investigator and will be 
reported. If a Grade 3 or 4 study drug-related adverse event occurs after a dose reduction, RRx-
001 will be discontinued. The dose modifications are listed below in the table below.

6.2.7 Dosing Delays/Dosing Modifications: Platinum Based Therapy 
This section applies to treatment regimens that include the investigational agent RRx-001 as 
follows:  
• Small Cell Carcinoma ARM 1 only 
• Ovarian ARM 1 only 
• Neuroendocrine  
• Non-Small Cell Lung Cancer (NSCLC) 
For SCC (ARM2) and EOC (ARM 2), “investigator’s choice” enrolled subjects, follow standard 
of care practice in accordance with the USPI FDA package insert and investigator discretion.  
In the event that a patient previously required a dose reduction during first line treatment, the 
patient may be started on a dose reduction during the initial cycle. This will be at the discretion 
of the principal investigator. At any time during study the investigator may choose to discontinue 
the partner agent due to toxicity, maintaining the platinum based agent (as a single agent).  
Any treatment delays beyond the protocol allowed 3-week (21 day) break must be approved by 
the medical monitor.   
The following regimens are allowed as defined in the respective treatment schema:   
1) Platinum agent:  Carboplatin or Cisplatin.  Platinum agents are given per the initial approval 
by the package insert (USPI FDA).  The following starting options are:  
a) Cisplatin will be initially dosed at 60-80 mg/m2 on day 1 every 3 weeks. 
b) Carboplatin will be initially dosed at an AUC of 5-6 on day 1 every 3 weeks. 
2) For the cohorts where a second agent will be combined with platinum, the partner agent will 
be given per the initial approval by the package insert (USPI FDA). The following starting 
options are:   
a) Etoposide will be initially dosed at 80-100 mg/m2 Days 1-3 every 3 weeks 
b) Paclitaxel will be initially dosed at 175-225 mg/m2 on Day 1 of every 3 weeks.  
c) Nab-Paclitaxel will be initially dosed at 100 mg/m2 on Days 1, 8, and 15 every 3 weeks 
d) Pemetrexed will be initially dosed at 500 mg/m2 IV over 10 minutes on Day 1 every 
3 weeks for up to 6 cycles

Data are not available in patients with creatinine clearances <15 mL/min and further dose 
reduction should be considered in these patients. 
Etoposide is associated with: 
a) 
Dose-limiting bone marrow suppression. The occurrence of a platelet count below 
50,000/mm3 or an absolute neutrophil count below 500/mm3 is an indication to withhold 
further therapy until the blood counts have sufficiently recovered 
b) The possible occurrence of an anaphylactic reaction manifested by chills, fever, 
tachycardia, bronchospasm, dyspnea, and hypotension. In case of anaphylactic reaction, 
the infusion should be terminated immediately, and may be followed by the 
administration of pressor agents, corticosteroids, antihistamines, or volume expanders at 
the discretion of the physician 
c) 
Injection site reactions. Closely monitor the infusion site for possible infiltration during 
drug administration. No specific treatment for extravasation reactions is known.

Hematological toxicity: neutrophils <1.5 x 109/L or platelets <100 x 109/L. Delay for one week. 
Repeat complete blood count. If within normal parameters resume treatment with 100% doses. 
If 2 or more delays, consider a 25% dose reduction. 
Renal impairment: CrCl (mL/min) >45 give 100% dose. If CrCl <45 not recommended.

6.4.4 Follow-Up Assessments 
Patients will be followed until death, or withdrawal of informed consent. Follow-up will consist 
of phone calls approximately every 8 weeks (± 7 days) to document survival.  If a patient, family 
member or healthcare proxy cannot be reached, medical records or the Social Security Death 
Index (SSDI) may be used to document survival.  For patients continuing to be imaged at the 
study site, a copy of the imaging and local radiology report will be made available upon request.  
Patients may choose to withdraw from making their imaging available during the follow-up 
period. 
6.5 Patient Discontinuation 
Patients may discontinue study treatment at any time.  Any patient who discontinues treatment 
will be encouraged to return to the study center to undergo treatment discontinuation 
assessments. The primary reason for discontinuation should be recorded.  Reasons for 
discontinuation of a patient by the investigator include, but are not limited to, the following:   
• Voluntary withdrawal from treatment (follow-up permitted); patients that withdraw from 
radiology follow-up should still be followed for overall survival 
• Voluntary withdrawal of consent (termination of treatment and follow-up), 
• Documented disease progression by RECIST v1.1 criteria after start of platinum doublets 
• Clinically significant deterioration of the patient’s condition prior to treatment 
discontinuation,  
• Patient noncompliance, 
• Experience of serious and unexpected toxicity, as defined in Section 5.1.1, 
• Investigator determination that it is not in the patient’s best interest to continue 
participation, 
• Pregnancy, 
• Development of second malignancy (except for basal cell carcinoma, squamous cell 
carcinoma of the skin, localized prostate, or cervical cancer) that requires treatment which 
would interfere with the study, 
• Lost to follow-up. 
6.6 Study Discontinuation 
Reasons for terminating the study may include, but are not limited to, the following: 
• Completion of the study. 
• The incidence or severity of adverse events in this study indicates a potential health hazard. 
• Withdrawal of EpicentRx Inc. approval. 
• Inaccurate or incomplete data recording. 
• Suggested by early stopping guidelines for futility of second or third line chemotherapy.   
• Suggested by early stopping guideline for risk of clinical deterioration during RRx-001 
treatment period.

7 STATISTICAL METHODS OF DATA ANALYSIS 
7.1 Study Design 
This study is designed to explore the potential of the epigenetic agent RRx-001 to sensitize 
patients who previously received a platinum based doublet regimen. RRx-001 is administered 
with autologous blood once weekly followed by or in combination with a protocol defined 
therapy.  
The primary endpoint is Overall Survival (OS) and Overall Response Rate (ORR). 
The four cohorts under consideration are patients with NSCLC, SCC, High Grade 
Neuroendocrine Tumors, or refractory resistant epithelial ovarian tumors (or MMMT of ovary or 
uterus) and who meet eligibility criteria defined in the inclusion / exclusion criteria.  
Stopping guidelines for safety in platinum therapy period of treatment - Stage 2 
If the limiting toxicity events convincingly exceed 30%, we will temporarily halt the study 
pending safety consultation. Specifically, we will apply a Bayesian toxicity monitoring rule that 
suspends the enrollment if the posterior probability of risk being larger than 0.30 is 70% or 
higher. The prior distribution was chosen to be beta (1, 5), representing our prior guess that 
limiting toxicities occur in 1 out of 6 patients and there is 90% chance that this toxicity rate is 
between 1.0% and 45%. The stopping boundaries along with corresponding operating 
characteristics are presented in the following tables based on 5000 simulations.

Amendment 10 Statistical updates:  
General design considerations, effective as of Amendment 10:  
1. Small Cell Carcinoma: Newly enrolled patients (post Amendment 10) will be allocated to 
one of two treatment arms using a 2-to-1 randomization ratio, (approximately 26 to 
Arm 1 and 13 to Arm 2). 
The two treatment arms are as follows: 
Arm 1: RRx-001 weekly for 3 weeks followed by up to 4 cycles of platinum plus etoposide 
chemotherapy ‘rechallenge’ and then RRx-001 & platinum maintenance (for patients 
with stable disease (SD) or better at discontinuation of platinum rechallenge) 
Arm 2: Standard of Care Investigator’s Choice Control Arm, treatment options of 
platinum plus etoposide, irinotecan or vinorelbine until progression or intolerable 
toxicity 
2. Ovarian: Newly enrolled patients (post Amendment 10) will be allocated to one of two 
treatment arms using a 2-to-1 randomization ratio, (approximately 26 to Arm 1 and 13 to 
Arm 2). 
The two treatment arms are as follows: 
Arm 1: RRx-001 weekly for 2 weeks followed by 2 cycles of carboplatin ‘rechallenge’ 
and then ‘maintenance’, cycling between 1 dose of RRx-001 followed by 2 cycles of 
carboplatin, which repeats until progression or intolerable toxicity 
Arm 2: Standard of Care Investigator’s Choice Control Arm, treatment options of one of 
the following: carboplatin, etoposide, doxil, gemcitabine, vinorelbine or taxane 
treatments until progression or intolerable toxicity 
3. Neuroendocrine: The only modification with amendment 09 forward to the existing 
treatment schedule is the addition of a RRx-001 maintenance for patients with > SD 
following discontinuation of platinum based chemotherapy (for up to 6 cycles).  
4. NSCLC: Patients enrolled post Amendment 09 will receive 3 consecutive doses of 
RRx-001, after which, RRx-001 is discontinued and platinum based chemotherapy is 
started for up to 6 cycles. In addition, a RRx-001 maintenance for patients with > SD 
following discontinuation of platinum based chemotherapy (for up to 6 cycles) was 
added.  
Sample size determination and power considerations: 
The extension stage of the study will approximately enroll 39 patients to the small cell carcinoma 
cohort and also 39 patients to the ovarian cohort. In each cohort, a 2-to-1 randomization 
allocation ratio will be employed (approximately 26 in Arm 1 and 13 in Arm 2, in each chort). 
The proposed sample size modification is motivated by recent clinical obersvations arising from 
current study data results. This upward sample size adjustment should provide sufficient 
precision to derive estimates of responses and time-to-event endpoints. Inferential statistics are 
not the main focus of this newly proposed focus study extension.

7.2 Efficacy Variables 
7.2.1 Primary Efficacy Variables 
The primary efficacy endpoint is OS defined as the time from the date of enrollment to disease 
progression or death from any cause.  Patients will be followed until their date of death, loss to 
follow-up, withdrawal of consent for further follow-up for survival or final database closure.   
Patients who are lost to follow-up or are not known to have disease progression at the time of 
data cut-off for analysis will be censored at last date shown to be alive.  Patients who do not have 
any follow up since enrollment will be censored at the date of enrollment. 
The primary efficacy analysis of OS will be based on the modified ITT population. Kaplan-
Meier estimates of the survival curves and the median survival times and their corresponding 
95% CI will be presented.  
Subgroup analyses of OS will be performed to assess whether the treatment effect is concordant 
among subgroups. The planned subgroup analyses are based on age category (<40 years, 40 to 
<65 years, and ≥65 years), race (Caucasian vs. other). Other subgroup analyses may be 
performed and specified in the statistical analysis plan. 
ORR is the other primary endpoint, which will be assessed at each radiographic assessment using 
RECIST v1.1 criterion. ORR will be defined as the proportion of patients with a CR or a PR per 
RECIST v1.1 based upon the best response as assessed; confirmation of response is not required. 
ORR will be analyzed using the CMH test stratified by the randomization stratification factors to 
assess the significance of the treatment effect on ORR. The treatment effect on ORR will be 
quantified using the odds ratio relative to the historical control. Clopper-Pearson 2-sided 95% 
confidence limits will be calculated for the proportion of patients with ORR. 
ORR analyses will be performed for the Efficacy Evaluable population. Patients who do not have 
measurable disease at baseline will be excluded from the population. 
In addition to representing ORR, the best response using response categories CR, PR, SD, PD 
and NE will be tabulated. The proportion of the response in each response category will be 
calculated. Patients who do not have any post-baseline tumor assessment will be counted under 
the category NE. 
ORR rate at best-confirmed response will also be assessed and analyzed using a similar approach 
as for Overall Response Rate. All patients meeting the eligibility criteria that have signed a 
consent form and have begun treatment will be evaluable for the primary endpoint.  Statistical 
analyses will be primarily descriptive in nature. Evidence of efficacy will consist of an ORR rate 
of 10% or higher in a particular treatment cohort. 
7.2.1.1 Transition Probability 
The transition probability between disease progression and disease amelioration attributable to 
resensitization will be estimated. A semi-Markov model will be used to capture the transition 
probability matrix between disease progression states (Jackson 2015, Sharples 2003).

The average time each patient spends in a given disease state will be estimated and its 95% 
confidence interval derived. The expected time spent healthy (or diseased) before death will also 
be estimated.   
7.2.1.2 Disease Control Rates (DCR) 
The percentage of patients who have achieved complete response, partial response and stable 
disease (as per RECIST v1.1). 
7.2.1.3 Progression Free Survival 
PFS defined from the time from registration to the time of the first radiographic documentation 
of objective progression as defined by RECIST v1.1 for platinum therapy or death from any 
cause. The analysis of PFS will be similar to the analysis of OS. 
7.2.1.4 Toxicity  
Rate of Grade 3 and Grade 4 hematologic toxicities between reintroduced platinum based 
chemotherapy and historical data. The analysis of this toxicity rate will use the CMH test 
stratified by the randomization stratification factors. The proportion of patients experiencing the 
given toxicity (by grade) will be quantified using the odds ratio relative to the historical control. 
Clopper-Pearson 2-sided 95% confidence limits will be calculated for the toxicity proportion (by 
grade). 
7.2.1.5 Analysis of Activity Data 
Descriptive statistics arranged by treatment group (within each of the four cohorts) are planned. 
Graphical depiction of the statistical summaries (ORR, DCR, OS, PFS) will accompany the 
tabular formatted data results for a more complete presentation of the statistical findings. 
Specifically, Kaplan-Meier curves and estimation of time-to-event medians with their 
corresponding 95% confidence intervals will be produced. ORR and DCR responses will be 
derived and the Clopper-Pearson method will be used to derive the responses 95% confidence 
intervals. 
Small Cell Carcinoma and Ovarian Patients enrolled to Amendment 10 or later will be 
analyzed separately (from patients enrolled prior to Amendment 10), the corresponding activity 
data analyses will be separated accordingly. Safety data summaries will be provided separately 
and in aggregation (pre-and-post Amendment 10). As of the time of Amendment 10 (and its 
execution), only newly enrolled patients (to the extension of the study, as of Amendment 10) will 
be required to consent and follow all required eligibility/randomization requirements. 
There will be two databases with separate database locks: 
1. An original database for patients enrolled prior to Amendment 10. This database will 
have its own database procedures and lock timelines. 
2. An extension database for patients enrolled to Amendment 10 or later with its own 
database lock procedures and timelines. 
NSCLC and Neuroendocrine enrolled to the study (pre & post Amendment 10) will be analyzed 
as a single group for each cancer type.

7.3 Safety Variables 
Safety data summary will be presented by study stage. Adverse events with RRx-001 and 
cumulative adverse events with a protocol defined therapy (description, timing, grade severity, 
seriousness, and relatedness) will be summarized using sample size frequency of occurrence 
percentage. Adverse event data will be descriptively evaluated by cohort and for overall patients.  
Incidence of TEAEs by MedDRA SOC, preferred term and relationship (Related/Not Related) to 
study drug will be summarized based on the safety population. Changes in the level of serum 
biomarkers, clinical laboratory abnormalities, and changes in physical exam and vital signs will 
be compared to baseline samples using one-sample tests (e.g., paired t test or Wilcoxon signed 
rank test).   
Adverse events will be coded by SOC and preferred term using MedDRA, version 18.1.  
Adverse event severity will be based on NCI CTCAE Grade (version 5.0). A TEAE is defined as 
an AE that was not present prior to treatment with study drug, but appeared following treatment 
or was present at treatment initiation, but worsened during treatment. 
Percentage and Time to non-hematologic toxicity Grades 3-5 adverse events will also be 
summarized using time-to-event techniques such as Kaplan-Meier curves. The median time to a 
given toxicity event (by grade) will be estimated (along with its 95% confidence interval) and 
descriptively compared to historical toxicity information. The hematologic toxicity Grade 3-5 
under consideration comprises anemia, thrombocytopenia, neutropenia, febrile neutropenia and 
infections. 
Amendment 10 Section Updates (Small Cell Carcinoma & Ovarian): 
In addition to the safety summary described above, safety summaries will be presented by 
treatment arm within the small cell carcinoma and ovarian cohorts.  
7.4 Statistical and Analytical Methods 
Besides explicitly mentioned variables and their analyses, all collected variables will be 
presented at least descriptively.  Categorical data will be analyzed using frequency tables.  
Longitudinal data will also be presented as change from baseline, if appropriate. 
The statistical analysis plan, including a comprehensive list of planned output, will describe all 
analyses in more depth. 
7.4.1 Statistical Model 
A two-sided log-rank test will be used to compare each disease cohort to the historical control 
cohort. Kaplan-Meier estimates will be derived for the one-sample disease cohort and the median 
with its 95% confidence interval estimates will be derived.  
7.4.2 Hypothesis Testing 
OS, ORR and PFS endpoints will be compared between the disease cohorts and the 
corresponding historical control.

7.4.3 Analysis Populations 
The following population definitions will be used to analyze selected endpoints using the 
appropriate subpopulation of the enrolled patients.  If the need arises, additional subpopulations 
will be defined in the statistical analysis plan.  
7.4.3.1 Safety Analysis Population 
The Safety Population will comprise all study patients who receive at least 1 dose of any study 
medication.  The safety population will be used for the analysis of all safety parameters.  For the 
purposes of this analysis, patients will be assigned to the treatment groups based on the 
treatments they actually received. 
7.4.3.2 Efficacy Analysis Population(s)  
• In NSCLC and neuroendocrine cohorts, all enrolled patients who receive study treatment 
will be included in the modified ITT population and analyzed according to the treatment 
schedule they were enrolled to.  
• For the small cell carcinoma and ovarian randomized patients, the modified intention-to-
treat will comprise all randomized patients who receive study drug, and will be analyzed 
as randomized.   
• The Per Protocol population is defined as the subset of modified ITT population who 
received at least one study treatment cycle and had no major violation of the protocol 
inclusion and exclusion criteria.  
All efficacy analyses will be based on the modified ITT population.  The primary and secondary 
efficacy analyses will be repeated using the Per Protocol population to confirm the overall study 
results.  Further efficacy analyses may be conducted as described in the statistical analysis plan. 
7.5 Power Considerations and Sample Size Determination 
The extension stage of the study will approximately enroll 39 patients to the small cell carcinoma 
cohort and also 39 patients to the ovarian cohort, both in a 2:1 randomization, respectively (26 in 
ARM 1 and 13 in ARM 2 for each). The sample size is based on clinical observations motivated 
by currently available study data results, and should provide sufficient precision to derive 
estimates of responses and time-to-event endpoints. Inferential statistics are not the main focus of 
this newly proposed focus study extension. 
7.6 Interim Analysis and Data Monitoring 
Safety data will be reviewed periodically to examine safety information, including TEAEs, 
SAEs, and deaths, and factors relating to quality of trial conduct will be reviewed. During Part 2, 
an IDMC will be established to review the safety data summaries and examine the findings of the 
interim futility analysis. 
All patients will be evaluable for toxicity from the time of their first treatment with protocol 
specified treatment until the end of protocol specified treatment.  However, cumulative adverse

events during the period of treatment will be continuously monitored. If the limiting toxicity 
events exceed 30%, the trial will be temporarily halted pending safety consultation. 
Efficacy will be assessed on a periodic basis to determine the best course for future development. 
OS, PFS and ORR will be evaluated at each data review when appropriate data maturity is 
achieved. 
Data Monitoring: Safety data will be reviewed periodically to examine safety information, 
including TEAEs, SAEs, toxicity, deaths, and factors relating to quality of trial conduct will be 
reviewed.  An informal DMC will be established to review the safety data summaries and 
examine the findings of the interim data summaries, and will consist of two physicians not 
involved in the conduct of this trial and one biostatistician. Administrative staff will assist the 
informal DMC with operational details and coordinate the generation of DMC minutes. 
DMC members will review safety analyses in order to investigate potential safety risks to the 
patients participating in the study that would suggest a change in study conduct or in the ICF. 
The DMC charter describes details including the primary responsibilities of the DMC, its 
relationship with other trial components, its membership, the purpose and timing of its meetings, 
statistical monitoring guidelines to be implemented, and statistical analysis for the open and 
closed sessions (if appropriate). The informal DMC Charter and meeting minutes will be 
submitted as part of the final Clinical Study Report. 
7.7 Institutional Review Board 
The PI must obtain IRB approval for the investigation.  Initial IRB approval and all materials 
approved by the IRB for this study including the patient consent form and recruitment materials 
must be maintained by the Investigator and made available for inspection. 
7.8 Data Quality Assurance 
Data will be collected via notes in the electronic medical record, radiological imaging and 
outside reports and entered into the appropriate Electronic Data Capture (EDC) Case Report 
Forms (CRFs).

8 ASSESSMENT OF SAFETY 
The safety of RRx-001 and other protocol defined therapy will be assessed through collection 
and analyses of adverse events (AEs) and laboratory tests. Patients will be assessed for safety 
through the duration of study while receiving protocol defined treatment. 
8.1 Specification of Safety Variables 
Safety assessments will consist of monitoring and reporting adverse events (AEs) and serious 
adverse events (SAEs) that are considered related to RRx-001 or protocol specified standard of 
care therapy (e.g., carboplatin, cisplatin, investigator’s choice treatment), all events of death, and 
any study specific issue of concern. 
8.1.1 Adverse Events 
An adverse event (AE) is defined as any new untoward medical occurrence or worsening of a 
pre-existing medical condition in a patient or clinical investigation patient administered an 
investigational (medicinal) product and that does not necessarily have a causal relationship with 
this treatment.  An AE can therefore be any unfavorable or unintended sign (including abnormal 
laboratory finding, for example), symptom or disease temporally associated with the use of 
investigational product, whether or not considered related to the investigational product. 
This includes the following: 
• AEs not previously observed in the patient that emerge during the protocol specified AE 
reporting period, including signs or symptoms associated with SCC, T790M- NSCLC, 
HGNEC, rEOC that were not present prior to the AE reporting period. 
• Complications that occur as a result of protocol-mandated interventions (e.g., invasive 
procedures such as biopsies). 
• Preexisting medical conditions (other than the condition being studied) judged by the 
investigator to have worsened in severity or frequency or changed in character during the 
protocol-specified AE reporting period. 
• Clinical progression of SCC, EGFR+ NSCLC, HGNEC or EOC should not be reported as 
an AE. 
 
8.1.2 Serious Adverse Events 
An AE should be classified as an SAE if: 
• It results in death (i.e., the AE actually causes or leads to death).  
• It is life threatening (i.e., the AE, in the view of the investigator, places the patient at 
immediate risk of death. It does not include an AE that, had it occurred in a more severe 
form, might have caused death.). 
• It requires or prolongs inpatient hospitalization.

• It results in persistent or significant disability/incapacity (i.e., the AE results in 
substantial disruption of the patient’s ability to conduct normal life functions). 
• It results in a congenital anomaly/birth defect in a neonate/infant born to a mother 
exposed to the investigational product. 
• It is considered a significant medical event by the investigator based on medical 
judgment (e.g., may jeopardize the patient or may require medical/surgical intervention to 
prevent one of the outcomes listed above). 
 
All AEs that do not meet any of the criteria for serious should be regarded as non-serious AEs. 
The terms “severe” and “serious” are not synonymous.  Severity (or intensity) refers to the grade 
of a specific AE, e.g., mild (Grade 1), moderate (Grade 2), or severe (Grade 3) myocardial 
infarction. “Serious” is a regulatory definition (see previous definition) and is based on patient or 
event outcome or action criteria usually associated with events that pose a threat to a patient’s 
life or functioning.  Seriousness (not severity) serves as the guide for defining regulatory 
reporting obligations from the Sponsor to applicable regulatory authorities.  
Severity and seriousness should be independently assessed when recording AEs and SAEs on the 
CRF. 
8.2 Methods and Timing for Assessing and Recording Safety Variables 
The investigator is responsible for ensuring that all AEs and SAEs that are observed or reported 
during the study are collected and reported to the FDA, IRB, and EpicentRx, Inc. in accordance 
with CFR 312.32 (IND Safety reporting). 
8.2.1 Adverse Event Reporting Period 
The study period during which all AEs and SAEs must be reported begins after informed consent 
is obtained and ends 30 days following the last administration of protocol specified treatment 
(i.e., RRx-001, carboplatin, cisplatin, investigator’s choice treatment, etc.) or study 
discontinuation/termination, whichever is earlier.  After this period, investigators should only 
report SAEs that are attributed to prior study treatment. 
8.2.2 Assessment of Adverse Events 
Investigators will assess the occurrence of AEs and SAEs at all patient evaluation time points 
during the study. All AEs and SAEs whether volunteered by the patient, discovered by study 
personnel during questioning, or detected through physical examination, laboratory test, or other 
means will be recorded in the patient’s medical record and on the appropriate AE or SAE CRF 
page. 
Each recorded AE or SAE will be described by its duration (i.e., start and end dates), severity 
(see Table 12), regulatory seriousness criteria if applicable, suspected relationship to the 
investigational product (see following guidance), and actions taken.

Death related to AE 
 
Note:  Regardless of severity, some events may also meet regulatory serious criteria.  Refer to definitions of an 
SAE (see Section 8.1.2). 
aUse these alternative definitions for Grade 1, 2, 3, and 4 events when the observed or reported AE is not in the 
NCI-CTCAE listing. 
 
To ensure consistency of AE and SAE causality assessments, investigators should apply the 
following general guideline: 
• YES 
There is a plausible temporal relationship between the onset of the AE and administration of the 
investigational product, and the AE cannot be readily explained by the patient’s clinical state, 
intercurrent illness, or concomitant therapies; and/or the AE follows a known pattern of response 
to the investigational product; and/or the AE abates or resolves upon discontinuation of the 
investigational product or dose reduction and, if applicable, reappears upon re-challenge. 
• NO 
Evidence exists that the AE has an etiology other than the investigational product 
(e.g., preexisting medical condition, underlying disease, intercurrent illness, or concomitant 
medication); and/or the AE has no plausible temporal relationship to administration of the 
investigational product (e.g., cancer diagnosed 2 days after first dose of study drug). 
Expected adverse events are those adverse events that are listed or characterized in the Product 
Label or current Investigator Brochure. 
Unexpected adverse events are those not listed in the Product Label or current Investigator 
Brochure or not identified. This includes adverse events for which the specific or severity is no 
consistent with the previous description.

8.2.3 Specific Instructions for Recording Adverse Events 
Investigators are strongly encouraged to use correct medical terminology/concepts when 
reporting AEs or SAEs and to avoid colloquialisms and abbreviations. 
a. Diagnosis vs. Signs and Symptoms 
If known at the time of reporting, a diagnosis should be reported rather than individual signs and 
symptoms. However, if a constellation of signs and/or symptoms cannot be medically 
characterized as a single diagnosis or syndrome at the time of reporting, it is ok to report the 
information that is currently available. If a diagnosis is subsequently established, it should be 
reported as follow-up information. 
b. Deaths 
All deaths that occur during the protocol-specified AE reporting period (see Section 8.1.2), 
regardless of attribution, will be reported to the appropriate parties. When recording a death, the 
event or condition that caused or contributed to the fatal outcome should be reported as the single 
medical concept. If the cause of death is unknown and cannot be ascertained at the time of 
reporting, report “Unexplained Death”. 
c. Preexisting Medical Conditions 
A preexisting medical condition is one that is present at the start of the study. Such conditions 
should be reported as medical and surgical history. A preexisting medical condition should be re-
assessed throughout the trial and reported as an AE or SAE only if the frequency, severity, or 
character of the condition worsens during the study. When reporting such events, it is important 
to convey the concept that the preexisting condition has changed by including applicable 
descriptors (e.g., “more frequent headaches”). 
d. Hospitalizations for Medical or Surgical Procedures 
Any AE that results in hospitalization or prolonged hospitalization should be documented and 
reported as an SAE. If a patient is hospitalized to undergo a medical or surgical procedure as a 
result of an AE, the event responsible for the procedure, not the procedure itself, should be 
reported as the SAE. For example, if a patient is hospitalized to undergo coronary bypass 
surgery, record the heart condition that necessitated the bypass as the SAE. 
Hospitalizations for the following reasons do not require reporting: 
• 
Hospitalization or prolonged hospitalization for diagnostic or elective surgical 
procedures for preexisting conditions 
• 
Hospitalization or prolonged hospitalization required to allow efficacy measurement 
for the study or 
• 
Hospitalization or prolonged hospitalization for scheduled therapy of the target 
disease of the study. 
e. Pregnancy 
If a female patient becomes pregnant while receiving investigational therapy or within 90 days 
after the last dose of study drug, a report should be completed and expeditiously submitted to the 
EpicentRx, Inc. Follow-up to obtain the outcome of the pregnancy should also occur. Abortion,

whether accidental, therapeutic, or spontaneous, should always be classified as serious, and 
expeditiously reported as an SAE. Similarly, any congenital anomaly/birth defect in a child born 
to a female patient exposed to the investigational product should be reported as an SAE. 
f. Post-Study Adverse Events 
The investigator should expeditiously report any SAE occurring after a patient has completed or 
discontinued study participation if attributed to prior investigational product exposure. If the 
investigator should become aware of the development of cancer or a congenital anomaly in a 
subsequently conceived offspring of a female patient who participated in the study, this should 
be reported as an SAE. 
8.3 Reporting Requirements for Adverse Events 
8.3.1 Expedited Reporting Requirements for Serious Adverse Events 
If an SAE occurs, the Sponsor and its designee are to be notified within 24 hours of awareness 
of the event by the Investigator. In particular, if the SAE is fatal or life-threatening, notification 
to the Sponsor or designee must be made immediately, irrespective of the extent of the available 
SAE information. This timeframe also applies to additional new information (follow up) on 
previously forwarded SAE reports as well as to the initial and follow up reporting of Exposure in 
Utero (Pregnancy) cases. 
In the rare event that the Investigator does not become aware of the occurrence of an SAE 
immediately (e.g., if an outpatient trial patient initially seeks treatment elsewhere), the 
Investigator is to report the event within 24 hours of first awareness of the SAE and to document 
the time of his/her first awareness of the SAE. 
For all SAEs, the Investigator is obligated to pursue and provide information to the Sponsor or 
designee in accordance with the timeframes for reporting specified above. In addition, an 
Investigator may be requested by the Sponsor or designee to obtain specific additional follow up 
information in an expedited fashion. This information may be more detailed than information 
captured on the AE CRF. In general, this will include a description of the AE in sufficient detail 
to allow for a complete medical assessment of the case and independent determination of 
possible causality. Information on other possible causes of the event, such as concomitant 
mediations and illnesses must be provided. In the case of a patient death, a summary of available 
autopsy findings must be submitted as soon as possible to Sponsor or designee.  
The completed SAE CRF page or MedWatch form should be emailed to EpicentRx’s Drug 
Safety Department at: 
 
SAEREPORTING@epicentrx.com 
 
The Medical Monitor, Dr. Bryan Oronsky can be reached at (408) 569-3202 (cell) or 
boronsky@epicentrx.com should any questions arise regarding an SAE or SAE reporting. 
Relevant follow-up information should be submitted to EpicentRx’s Drug Safety as soon as it 
becomes available and/or upon request.

MedWatch 3500A Reporting Guidelines 
In addition to completing appropriate patient demographic and suspect medication information, 
the report should include the following information within the Event Description (Section 5) of 
the MedWatch 3500A form (http://www.fda.gov/medwatch/index.html): 
• Treatment regimen (dosing frequency, combination therapy) 
• Protocol description (and number, if assigned) 
• Description of event, severity, treatment, and outcome, if known 
• Supportive laboratory results and diagnostics 
• Investigator’s assessment of the relationship of the adverse event to each investigational 
product and suspect medication 
 
Follow-up information 
Additional information may be added to a previously submitted report by any of the following 
methods: 
• Adding to the original MedWatch 3500A report and submitting it as follow-up 
• Adding supplemental summary information and submitting it as follow-up with the 
original MedWatch 3500A form  
• Summarizing new information and faxing it with a cover letter including patient 
identifiers (i.e., D.O.B., initials, patient number), protocol description and number, if 
assigned, suspect drug, brief adverse event description, and notation that additional or 
follow-up information is being submitted (The patient identifiers are important so that the 
new information is added to the correct initial report.) 
Occasionally, EpicentRx may contact the reporter for additional information, clarification or 
current status of the patient for whom an adverse event was reported.  For questions regarding 
STEAE reporting, you may contact the EpicentRx Drug Safety representative (Bryan Oronsky, 
MD, (408) 569-3202). 
• The Human Research Protections Program (HRPP) must be notified within 10 business 
days of “any unanticipated problems involving risk to patients or others” (UPR).  
The following events meet the definition of UPR: 
1. 
Any serious event (injuries, side effects, deaths or other problems), which in the 
opinion of the Principal Investigator was unanticipated, involved risk to patients 
or others, and was possibly related to the research procedures. 
2. 
Any serious accidental or unintentional change to the IRB-approved protocol that 
alters the level of risk. 
3. 
Any deviation from the protocol taken without prior IRB review to eliminate 
apparent immediate hazard to a research patient.

4. 
Any new information (e.g., publication, safety monitoring report, updated sponsor

to the risk/benefit ratio for the research. 
5. 
Any breach in confidentiality that may involve risk to the patient or others. 
6. 
Any complaint of a patient that indicates an unanticipated risk or that cannot be 
resolved by the Principal Investigator. 
8.3.2 Routine Reporting of Adverse Events 
• The HRPP will be notified of any adverse events that are not unanticipated problems 
involving risk to patients or other (non-UPRs) at the time of the annual Continuing 
Review. 
8.4 Type and Duration of Follow-Up of Patients After Adverse Events 
All AEs and SAEs that are encountered during the protocol-specified AE reporting period that 
are considered at least possibly related to the study drug should be followed to their resolutions, 
or until the investigator assesses them as stable, or the patient is lost to follow-up.  Resolution of 
AEs and SAEs (with dates) should be documented on the appropriate AE CRF page and in the 
patient’s medical record to facilitate source data verification. 
Recording of Adverse Events includes the study period during protocol specified treatment 
(i.e., RRx-001, carboplatin, cisplatin, investigator’s choice treatment, etc.) until the patient is off 
study.  
For some SAEs, the Sponsor or its designee may follow-up by telephone, fax, electronic mail, 
and/or a monitoring visit to obtain additional case details deemed necessary to appropriately 
evaluate the SAE report (e.g., hospital discharge summary, consultant report, or autopsy report).

9.3 Institutional Review Board Approval 
This protocol, the informed consent document, and relevant supporting information must be 
submitted to the IRB for review and must be approved before the study is initiated.  In addition, 
any advertising materials must be approved by the IRB.  The study will be conducted in 
accordance with U.S. FDA, applicable national and local health authority, and IRB requirements. 
The Principal Investigator is responsible for keeping the IRB apprised of the progress of the 
study and of any changes made to the protocol as deemed appropriate, but in any case, the IRB 
must be updated at least once a year.  The Principal Investigator must also keep the IRB 
informed of any significant adverse events. 
Investigators are required to promptly notify their respective IRB of all adverse drug reactions 
that are both serious and unexpected.  This generally refers to serious adverse events that are not 
already identified in the Investigator Brochure and that are considered possibly or probably 
related to the study drug by the investigator.  Investigators must forward to their IRB any written 
safety report or update provided by EpicentRx (e.g., IND safety report, Investigator Brochure, 
safety amendments and updates, etc.). 
9.4 Study Monitoring Requirements 
The Sponsor will designate a Sponsor’s Study Monitor (i.e., clinical research associate (CRA)) 
who will be responsible for monitoring this clinical trial. The Sponsor’s Study Monitor will 
monitor the study conduct; insure the proper completion and retention of source documentation 
completion and retention, accurate study drug accountability records and prompt data entry to 
CRF. To this end, the Sponsor’s Study Monitor will visit the study site at suitable intervals and 
be in frequent contact through verbal and written communication.  Monitoring may also be 
carried out remotely.  It is essential that the Sponsor’s Study Monitor have access to all 
documents (related to the study and the individual participants) at any time these are requested. 
In turn, the Sponsor’s Study Monitor will adhere to all requirements for patient confidentiality as 
outlined in the Informed consent form (ICF). The Investigator(s) or their representative(s) will be 
expected to cooperate with the Sponsor’s Study Monitor, to be available during a portion of the 
monitoring visit to answer questions, and to provide any missing information. Investigator(s) or 
their representative(s) are required to respond in writing to any deficiencies or protocol 
deviations noted by the monitor in the site visit report. 
9.5 Data Collection 
Study documentation includes all Case Report Forms, data correction forms or queries, source 
documents, correspondence, monitoring logs/letters, and regulatory documents (e.g., protocol 
and amendments, IRB correspondence and approval, signed patient consent forms).

11 APPENDICES 
Appendix A. Response evaluation criteria in solid tumors  
Tumor assessments will be made according to the schedule of assessments. Response and 
progression will be evaluated using RECIST v1.1 [Eisenhauer et al. 2009]. 
A1 
MEASURABILITY OF TUMOR AT BASELINE 
A1.1 Definitions 
At baseline, tumor lesions will be categorized as follows: 
A1.1.1 
Measurable 
Tumor lesions: must be accurately measured in at least one dimension (longest diameter in the 
plane of measurements is to be recorded) with a minimum size of: 
• 10 mm by CT scan (CT scan slice thickness no greater than 5 mm). 
• 10 mm caliper measurement by clinical exam (lesions which cannot be accurately 
measured with calipers should be recorded as non-measureable). 
• 20 mm by chest X-ray. 
 
Malignant lymph nodes: to be considered pathologically enlarged and measurable, a lymph node 
must be >= 15 mm in short axis when assessed by CT scan. At baseline and in follow-up, only 
the short axis will be measured and followed. 
A1.1.2 
Non-measurable 
All other lesions, including small lesions (longest diameter < 10 mm or pathological lymph 
nodes with >= 10 to < 15 mm short axis) as well as truly non-measurable lesions. Lesions 
considered truly non-measurable include: leptomeningeal disease, ascites, pleural or pericardial 
effusion, inflammatory breast disease, lymphangitic involvement of skin or lung, abdominal 
masses/abdominal organomegaly identified by physical exam that is not measurable by 
reproducible imaging techniques. 
A1.1.3 
Special considerations regarding lesion measurability 
Bone lesions, cystic lesions, and lesions previously treated with local therapy require particular 
comment: 
Bone lesions: 
• Bone scan, PET scan or plain films are not considered adequate imaging techniques to 
measure bone lesions. However, these techniques can be used to confirm the presence or 
disappearance of bone lesions. 
• Lytic bone lesions or mixed lytic-blastic lesions, with identifiable soft tissue components, that 
can be evaluated by cross sectional imaging techniques such as CT or MRI can be considered 
as measurable lesions if the soft tissue component meets the definition of measurability 
described above. 
• Blastic bone lesions are non-measurable.

Cystic lesions: 
• Lesions that meet the criteria for radiographically defined simple cysts should not be 
considered as malignant lesions (neither measurable nor non-measurable) since they are, by 
definition, simple cysts. 
• ‘Cystic lesions’ thought to represent cystic metastases can be considered as measurable 
lesions, if they meet the definition of measurability described above. However, if noncystic 
lesions are present in the same subject, these are preferred for selection as target lesions. 
 
Lesions with prior local treatment: 
• Tumor lesions situated in a previously irradiated area, or in an area subjected to other loco-
regional therapy, are usually not considered measurable unless there has been demonstrated 
progression in the lesion. Study protocols should detail the conditions under which such 
lesions would be considered measurable. 
 
A1.2 Specifications by methods of measurements 
 
A1.2.1 
Measurement of lesions 
All measurements should be recorded in metric notation, using calipers if clinically assessed. All 
baseline evaluations should be performed as close as possible to the treatment start and never 
more than 4 weeks before the beginning of the treatment. 
A1.2.2 
Method of assessment 
A diagnostic CT with contrast imaging will be permitted as the baseline evaluation at the 
screening assessment and for lesion assessment. Imaging based evaluation should always be 
done rather than clinical examination unless the lesion(s) being followed cannot be imaged but 
are assessable by clinical exam. 
Clinical lesions: Clinical lesions will only be considered measurable when they are superficial 
and P10mm diameter as assessed using calipers (e.g. skin nodules). For the case of skin lesions, 
documentation by color photography including a ruler to estimate the size of the lesion is 
suggested. As noted above, when lesions can be evaluated by both clinical exam and imaging, 
imaging evaluation should be undertaken since it is more objective and may also be reviewed at 
the end of the study. 
Chest X-ray: Chest CT is preferred over chest X-ray, particularly when progression is an 
important endpoint, since CT is more sensitive than X-ray, particularly in identifying new 
lesions. However, lesions on chest X-ray may be considered measurable if they are clearly 
defined and surrounded by aerated lung. 
CT: For the purposes of this study a diagnostic CT with contrast will be used for lesion 
assessment.  
Ultrasound: Ultrasound is not useful in assessment of lesion size and should not be used as a 
method of measurement. Ultrasound examinations cannot be reproduced in their entirety for 
independent review at a later date and, because they are operator dependent, it cannot be 
guaranteed that the same technique and measurements will be taken from one assessment to the 
next. If new lesions are identified by ultrasound in the course of the study, confirmation by MRI 
is advised.

Endoscopy, laparoscopy: The utilization of these techniques for objective tumor evaluation is 
not advised. However, they can be useful to confirm complete pathological response when 
biopsies are obtained or to determine relapse in trials where recurrence following complete 
response or surgical resection is an endpoint. 
Tumor markers: Tumor markers alone cannot be used to assess objective tumor response. If 
markers are initially above the upper normal limit, however, they must normalize for a patient to 
be considered in complete response. Because tumor markers are disease specific, instructions for 
their measurement should be incorporated into protocols on a disease specific basis.  
Cytology, histology: These techniques can be used to differentiate between PR and CR in rare 
cases if required by protocol (for example, residual lesions in tumor types such as germ cell 
tumors, where known residual benign tumors can remain). When effusions are known to be a 
potential adverse effect of treatment (e.g. with certain taxane compounds or angiogenesis 
inhibitors), the cytological confirmation of the neoplastic origin of any effusion that appears or 
worsens during treatment can be considered if the measurable tumor has met criteria for response 
or stable disease in order to differentiate between response (or stable disease) and progressive 
disease. 
B2 
TUMOR RESPONSE EVALUATION 
 
B2.1 
Baseline documentation of ‘target’ and ‘non-target’ lesions 
When more than one measurable lesion is present at baseline all lesions up to a maximum of five 
lesions total (and a maximum of two lesions per organ) representative of all involved organs 
should be identified as target lesions and will be recorded and measured at baseline (this means 
in instances where patients have only one or two organ sites involved a maximum of two and 
four lesions respectively will be recorded).  
Target lesions should be selected on the basis of their size (lesions with the longest diameter), be 
representative of all involved organs, but in addition should be those that lend themselves to 
reproducible repeated measurements. It may be the case that, on occasion, the largest lesion does 
not lend itself to reproducible measurement in which circumstance the next largest lesion which 
can be measured reproducibly should be selected.  
Lymph nodes merit special mention since they are normal anatomical structures which may be 
visible by imaging even if not involved by tumor. Pathological nodes which are defined as 
measurable and may be identified as target lesions must meet the criterion of a short axis of 
P15mm by CT scan. Only the short axis of these nodes will contribute to the baseline sum. The 
short axis of the node is the diameter normally used by radiologists to judge if a node is involved 
by solid tumor. Nodal size is normally reported as two dimensions in the plane in which the 
image is obtained (for CT scan this is almost always the axial plane; for MRI the plane of 
acquisition may be axial, sagittal or coronal). The smaller of these measures is the short axis. 
For example, an abdominal node which is reported as being 20mm· 30mm has a short axis of 
20mm and qualifies as a malignant, measurable node. In this example, 20mm should be recorded 
as the node measurement. All other pathological nodes (those with short axis P10mm but 
<15 mm) should be considered non-target lesions. Nodes that have a short axis <10mm are 
considered non-pathological and should not be recorded or followed.

A sum of the diameters (longest for non-nodal lesions, short axis for nodal lesions) for all target 
lesions will be calculated and reported as the baseline sum diameters. If lymph nodes are to be 
included in the sum, then as noted above, only the short axis is added into the sum. The baseline 
sum diameters will be used as reference to further characterize any objective tumor regression in 
the measurable dimension of the disease. 
All other lesions (or sites of disease) including pathological lymph nodes should be identified as 
non-target lesions and should also be recorded at baseline. Measurements are not required and 
these lesions should be followed as ‘present’, ‘absent’, or in rare cases ‘unequivocal progression’ 
(more details to follow). In addition, it is possible to record multiple non-target lesions involving 
the same organ as a single item on the case record form (e.g. ‘multiple enlarged pelvic lymph 
nodes’ or ‘multiple liver metastases’). 
B2.3 
Response criteria 
This section provides the definitions of the criteria used to determine objective tumor response 
for target lesions. 
B2.3.1 
Evaluation of target lesions 
Complete Response (CR):  
Disappearance of all target lesions. Any pathological lymph nodes 
(whether target or non-target) must have reduction in short axis to 
<10 mm. 
Partial Response (PR):  
At least a 30% decrease in the sum of diameters of target lesions, 
taking as reference the baseline sum diameters. 
Progressive Disease (PD):  
At least a 20% increase in the sum of diameters of target lesions, 
taking as reference the smallest sum on study (this includes the 
baseline sum if that is the smallest on study). In addition to the 
relative increase of 20%, the sum must also demonstrate an 
absolute increase of at least 5 mm. (Note: the appearance of one or 
more new lesions is also considered progression). 
Stable Disease (SD):  
Neither sufficient shrinkage to qualify for PR nor sufficient 
increase to qualify for PD, taking as reference the smallest sum 
diameters while on study.  
 
B2.3.2 
Special notes on the assessment of target lesions 
Lymph nodes. Lymph nodes identified as target lesions should always have the actual short axis 
measurement recorded (measured in the same anatomical plane as the baseline examination), 
even if the nodes regress to below 10mm on study. This means that when lymph nodes are 
included as target lesions, the ‘sum’ of lesions may not be zero even if complete response criteria 
are met, since a normal lymph node is defined as having a short axis of <10mm. Case report 
forms or other data collection methods may therefore be designed to have target nodal lesions 
recorded in a separate section where, in order to qualify for CR, each node must achieve a short 
axis <10mm. For PR, SD and PD, the actual short axis measurement of the nodes is to be 
included in the sum of target lesions. 
Target lesions that become ‘too small to measure’. While on study, all lesions (nodal and non-
nodal) recorded at baseline should have their actual measurements recorded at each subsequent 
evaluation, even when very small (e.g. 2 mm). However, sometimes lesions or lymph nodes

Page 79 of 99 
which are recorded as target lesions at baseline become so faint on MRI scan that the radiologist 
may not feel comfortable assigning an exact measure and may report them as being ‘too small to 
measure’. When this occurs it is important that a value be recorded on the case report form. If it 
is the opinion of the radiologist that the lesion has likely disappeared, the measurement should be 
recorded as 0mm. If the lesion is believed to be present and is faintly seen but too small to 
measure, a default value of 5 mm should be assigned (Note: It is less likely that this rule will be 
used for lymph nodes since they usually have a definable size when normal and are frequently 
surrounded by fat such as in the retroperitoneum; however, if a lymph node is believed to be 
present and is faintly seen but too small to measure, a default value of 5mm should be assigned 
in this circumstance as well).  The measurement of these lesions is potentially non-reproducible; 
therefore providing this default value will prevent false responses or progressions based upon 
measurement error. To reiterate, however, if the radiologist is able to provide an actual measure, 
that should be recorded, even if it is below 5 mm. 
Lesions that split or coalesce on treatment. When non-nodal lesions ‘fragment’, the longest 
diameters of the fragmented portions should be added together to calculate the target lesion sum. 
Similarly, as lesions coalesce, a plane between them may be maintained that would aid in 
obtaining maximal diameter measurements of each individual lesion. If the lesions have truly 
coalesced such that they are no longer separable, the vector of the longest diameter in this 
instance should be the maximal longest diameter for the ‘coalesced lesion’. 
B2.3.3 
Evaluation of non-target lesions 
This section provides the definitions of the criteria used to determine the tumor response for the 
group of non-target lesions. While some non-target lesions may actually be measurable, they 
need not be measured and instead should be assessed only qualitatively at the time points 
specified in the protocol. 
Complete Response (CR):  
Disappearance of all non-target lesions and normalization of tumor 
marker level. All lymph nodes must be non-pathological in size 
(<10 mm short axis). 
Non-CR/Non-PD:  
Persistence of one or more non-target lesion(s) and/or maintenance 
of tumor marker level above the normal limits. 
Progressive Disease (PD):  
Unequivocal progression (see comments below) of existing non-
target lesions. (Note: the appearance of one or more new lesions is 
also considered progression).  
 
B2.3.4 
Special notes on assessment of progression of non-target disease 
The concept of progression of non-target disease requires additional explanation as follows: 
When the patient also has measurable disease. In this setting, to achieve ‘unequivocal 
progression’ on the basis of the non-target disease, there must be an overall level of substantial 
worsening in non-target disease such that, even in presence of SD or PR in target disease, the 
overall tumor burden has increased sufficiently to merit discontinuation of therapy. A modest 
‘increase’ in the size of one or more non-target lesions is usually not sufficient to quality for 
unequivocal progression status. The designation of overall progression solely on the basis of 
change in non-target disease in the face of SD or PR of target disease will therefore be extremely 
rare.

When the patient has only non-measurable disease. This circumstance arises in some phase III 
trials when it is not a criterion of study entry to have measurable disease. The same general 
concepts apply here as noted above, however, in this instance there is no measurable disease 
assessment to factor into the interpretation of an increase in non-measurable disease burden. 
Because worsening in non-target disease cannot be easily quantified (by definition: if all lesions 
are truly non-measurable) a useful test that can be applied when assessing patients for 
unequivocal progression is to consider if the increase in overall disease burden based on the 
change in non-measurable disease is comparable in magnitude to the increase that would be 
required to declare PD for measurable disease: i.e.an increase in tumor burden representing an 
additional 73% increase in ‘volume’ (which is equivalent to a 20% increase diameter in a 
measurable lesion). Examples include an increase in a pleural effusion from ‘trace’ to ‘large’, an 
increase in lymphangitic disease from localized to widespread, or may be described in protocols 
as ‘sufficient to require a change in therapy’. If ‘unequivocal progression’ is seen, the patient 
should be considered to have had overall PD at that point. While it would be ideal to have 
objective criteria to apply to non-measurable disease, the very nature of that disease makes it 
impossible to do so, therefore the increase must be substantial.  
B2.4.5 
New lesions 
The appearance of new malignant lesions denotes disease progression; therefore, some 
comments on detection of new lesions are important. There are no specific criteria for the 
identification of new radiographic lesions; however, the finding of a new lesion should be 
unequivocal: i.e. not attributable to differences in scanning technique, change in imaging 
modality or findings thought to represent something other than tumor (for example, some ‘new’ 
bone lesions may be simply healing or flare of pre-existing lesions). This is particularly 
important when the patient’s baseline lesions show partial or complete response.  
A lesion identified on a follow-up study in an anatomical location that was not scanned at 
baseline is considered a new lesion and will indicate disease progression. An example of this is 
the patient who has visceral disease at baseline and while on study has a CT or MRI brain 
ordered which reveals metastases. The patient’s brain metastases are considered to be evidence 
of PD even if he/she did not have brain imaging at baseline. 
If a new lesion is equivocal, for example because of its small size, continued therapy and follow-
up evaluation will clarify if it represents truly new disease. If repeat scans confirm there is 
definitely a new lesion, then progression should be declared using the date of the initial scan. 
While FDG-PET response assessments need additional study, it is sometimes reasonable to 
incorporate the use of FDG-PET scanning to complement CT scanning in assessment of 
progression (particularly possible ‘new’ disease). New lesions on the basis of FDG-PET imaging 
can be identified according to the following algorithm: 
a. Negative FDG-PET at baseline, with a positive FDG-PET at follow-up is a sign of PD 
based on a new lesion. 
b. No FDG-PET at baseline and a positive FDG-PET at follow- up: 
If the positive FDG-PET at follow-up corresponds to a new site of disease confirmed by 
CT, this is PD. If the positive FDG-PET at follow-up is not confirmed as a new site of 
disease on CT, additional follow-up CT scans are needed to determine if there is truly 
progression occurring at that site (if so, the date of PD will be the date of the initial 
abnormal FDG-PET scan). If the positive FDG-PET at follow-up corresponds to a pre-

existing site of disease on CT that is not progressing on the basis of the anatomic images, 
this is not PD. 
B2.4 
Evaluation of best overall response  
The best overall response is the best response recorded from the start of the study treatment until 
the end of treatment taking into account any requirement for confirmation. On occasion a 
response may not be documented until after the end of therapy so protocols should be clear if 
post-treatment assessments are to be considered in determination of best overall response. 
Protocols must specify how any new therapy introduced before progression will affect best 
response designation. The patient’s best overall response assignment will depend on the findings 
of both target and non-target disease and will also take into consideration the appearance of new 
lesions. Furthermore, depending on the nature of the study and the protocol requirements, it may 
also require confirmatory measurement. Specifically, in non-randomized trials where response is 
the primary endpoint, confirmation of PR or CR is needed to deem either one the ‘best overall 
response’. This is described further below. 
B2.4.1 
Time point response 
It is assumed that at each protocol specified time point, a response assessment occurs. Table 1 
provides a summary of the overall response status calculation at each time point for patients who 
have measurable disease at baseline. 
When patients have non-measurable (therefore non-target) disease only, Table 2 is to be used.

When no imaging/measurement is done at all at a particular time point, the patient is not

assessment, usually the case is also considered NE at that time point, unless a convincing 
argument can be made that the contribution of the individual missing lesion(s) would not change

the assigned time point response. This would be most likely to happen in the case of PD. For 
example, if a patient had a baseline sum of 50 mm with three measured lesions and at follow-up 
only two lesions were assessed, but those gave a sum of 80 mm, the patient will have achieved 
PD status, regardless of the contribution of the missing lesion. 
B2.4.3 
Best overall response: all time points 
The best overall response is determined once all the data for the patient is known. 
Best response determination in trials where confirmation of complete or partial response IS NOT 
required: Best response in these trials is defined as the best response across all time points (for 
example, a patient who has SD at first assessment, PR at second assessment, and PD on last 
assessment has a best overall response of PR). When SD is believed to be best response, it must 
also meet the protocol specified minimum time from baseline. If the minimum time is not met 
when SD is otherwise the best time point response, the patient’s best response depends on the 
subsequent assessments. For example, a patient who has SD at first assessment, PD at second 
and does not meet minimum duration for SD, will have a best response of PD. The same patient 
lost to follow-up after the first SD assessment would be considered unevaluable. 
Best response determination in trials where confirmation of complete or partial response IS 
required: Complete or partial responses may be claimed only if the criteria for each are met at a 
subsequent time point as specified in the protocol (generally 4 weeks later). In this circumstance, 
the best overall response can be interpreted as in Table 3.

Special notes on response assessment 
When nodal disease is included in the sum of target lesions and the nodes decrease to ‘normal’ 
size (<10 mm), they may still have a measurement reported on scans. This measurement should 
be recorded even though the nodes are normal in order not to overstate progression should it be 
based on increase in size of the nodes. As noted earlier, this means that patients with CR may not 
have a total sum of ‘zero’ on the case report form (CRF).

In trials where confirmation of response is required, repeated ‘NE’ time point assessments may 
complicate best response determination. The analysis plan for the trial must address how missing 
data/assessments will be addressed in determination of response and progression. For example, 
in most trials it is reasonable to consider a patient with time point responses of PR-NE-PR as a 
confirmed response. 
Patients with a global deterioration of health status requiring discontinuation of treatment 
without objective evidence of disease progression at that time should be reported as 
‘symptomatic deterioration’. Every effort should be made to document objective progression 
even after discontinuation of treatment. Symptomatic deterioration is not a descriptor of an 
objective response: it is a reason for stopping study therapy. The objective response status of 
such patients is to be determined by evaluation of target and non-target disease as shown in 
Tables 1–3. 
Conditions that define ‘early progression, early death and inevaluability’ are study specific and 
should be clearly described in each protocol (depending on treatment duration, treatment 
periodicity). 
In some circumstances it may be difficult to distinguish residual disease from normal tissue. 
When the evaluation of complete response depends upon this determination, it is recommended 
that the residual lesion be investigated (fine needle aspirate/biopsy) before assigning a status of 
complete response. FDG-PET may be used to upgrade a response to a CR in a manner similar to 
a biopsy in cases where a residual radiographic abnormality is thought to represent fibrosis or 
scarring. The use of FDG-PET in this circumstance should be prospectively described in the 
protocol and supported by disease specific medical literature for the indication. However, it must 
be acknowledged that both approaches may lead to false positive CR due to limitations of FDG-
PET and biopsy resolution/sensitivity. 
For equivocal findings of progression (e.g., very small and uncertain new lesions; cystic changes 
or necrosis in existing lesions), treatment may continue until the next scheduled assessment. If at 
the next scheduled assessment, progression is confirmed, the date of progression should be the 
earlier date when progression was suspected. 
B2.5 
Confirmatory measurement/duration of response 
B2.5.1 
Confirmation 
In non-randomized trials where response is the primary endpoint, confirmation of PR and CR is 
required to ensure responses identified are not the result of measurement error. This will also 
permit appropriate interpretation of results in the context of historical data where response has 
traditionally required confirmation in such trials. However, in all other circumstances, i.e. in 
randomized trials (Phase II or III) or studies where stable disease or progression are the primary 
endpoints, confirmation of response is not required since it will not add value to the 
interpretation of trial results. However, elimination of the requirement for response confirmation 
may increase the importance of central review to protect against bias, in particular in studies that 
are not blinded. 
In the case of SD, measurements must have met the SD criteria at least once after study entry at a 
minimum interval that is defined in the study protocol.

B2.5.2 
Duration of overall response 
The duration of overall response is measured from the time measurement criteria are first met for 
CR/PR (whichever is first recorded) until the first date that recurrent or progressive disease is 
objectively documented (taking as reference for progressive disease the smallest measurements 
recorded on study). 
The duration of overall complete response is measured from the time measurement criteria are 
first met for CR until the first date that recurrent disease is objectively documented. 
B2.5.3 
Duration of stable disease 
Stable disease is measured from the start of the treatment (in randomized trials, from date of 
randomization) until the criteria for progression are met, taking as reference the smallest sum on 
study (if the baseline sum is the smallest, this is the reference for calculation of PD). 
The clinical relevance of the duration of stable disease varies in different studies and diseases. If 
the proportion of patients achieving stable disease for a minimum period of time is an endpoint 
of importance in a particular trial, the protocol should specify the minimal time interval required 
between two measurements for determination of stable disease. 
Note: The duration of response and stable disease as well as the progression-free survival are 
influenced by the frequency of follow-up after baseline evaluation. It is not in the scope of this 
guideline to define a standard follow-up frequency. The frequency should take into account 
many parameters including disease types and stages, treatment periodicity and standard practice. 
However, these limitations of the precision of the measured endpoint should be taken into 
account if comparisons between trials are to be made.

1. 
Full physical exam is required at Screening. Subsequent physical exams may be symptom-directed. Each PE must include vital signs and weight. 
2. 
Screening imaging must be obtained within 14 days prior to C0D1. A diagnostic CT with contrast must be performed at the end of Cycle 0, prior to initiation of platinum 
treatment, then every 2 cycles from start of platinum treatment (every 2 cycles ±7 Days) during the Platinum Rechallenge. SCC patients also require a Brain MRI within 8 
weeks prior to C0D1 (does not need to be repeated if SOC imaging performed within window; head CT is allowed if MRI is contraindicated). Lesion assessment will be by 
RECIST v1.1.  In addition to local assessment, upon request, all imaging performed while patient is ‘on-study’ is to be sent to EpicentRx within six (6) weeks of procedure visit 
for independent radiology review. Reference Appendix F for format and shipping instructions.  During the ‘follow-up period’, for subjects continuing to be imaged at the study 
site, a copy of the imaging and local radiology report will be made available upon request.  Subjects may choose to withdraw from making their imaging available during the 
follow-up period (once they are ‘off-study’). 
3. 
Premedication with 10 mg of dexamethasone, or a similar corticosteroid, and a low-dose aspirin (81 mg) or Acetaminophen (500 mg) is required within 2 hours prior to the 
infusion of RRx-001 blood mix. If patient is already receiving dexamethasone or equivalent corticosteroid, premedication with dexamethasone should not be given. 
4. 
During the ‘Platinum Rechallenege’, Administer carboplatin AUC 5-6 IV on day 1 or cisplatin 60-80 mg/m2 IV on day 1 plus etoposide per protocol and approved package 
insert every 21 days for up to 4 cycles. 
5. 
During the RRx-001 Priming period for RRx-001 dosing visits on Day 1 and Day 8, the LDH lab value should be processed and sent to EpicentRx (entered into EDC or emailed 
to study manager) within 48 hours of test blood collection. If LDH value increases by > 25% from Day 1 to Day 8, RRx-001 is to be discontinued and Platinum Rechallenge 
will begin 1 week sooner than scheduled (skipping the RRx-001 Priming Period Day 15 visit).  
6. 
Only to be performed if subject is a smoker. During screening and Day 1 of Cycle 4 only.  
7. 
New tumor biopsy, if feasible, will performed on an optional basis prior to infusion of RRx-001 (baseline) and prior to initial platinum rechallange Day 1 (up to 7 Days prior but 
following discontinuation of RRx-001).  Archival tissue, if available, will be collected at baseline.  For details regarding the processing of samples please refer to the latest study 
lab manual. 
8. 
For women of childbearing potential (WOCBP), a negative serum or urine pregnancy test is required prior to entering this study WOCBP and men whose partners are able to 
become pregnant will be asked to use non-hormonal methods of contraception for the entire duration of the study and for up to 90 days after their last dose with RRx-001 and 
through platinum phase. 
9. 
To be collected and sent to sponsor-designated central lab and may be collected up to 3 days prior to treatment administration. Blood samples will be drawn from all subjects by 
venipuncture or central venous catheter. For detailed collection, processing, and shipment requirements reference the Collection Flow Chart in the latest study lab manual. 
10. If subject demonstrates progressive disease (PD) during platinum treatment, treatment will be discontinued and subject will complete End of Study (EOS) visit within 30 days of 
termination of platinum dosing and move into follow-up period. If subject has > SD at discontinuation of Platinum Rechallenge period, subject continues onto 
maintenance portion of ARM 1 (see section below). 
11. Follow-up Period begins when patient has PD during Platinum Rechallenge or RRx-001/Platinum Maintenance treatment, or discontinues treatment for any other reason. 
Subjects with stable disease or better (SD, PR or CR) at discontinuation of Platinum Rechallenge continue into the RRx-001/Platinum Maintenance until progression. Survival 
contact will occur via medical record review, telephone call or Social Security Death Index every 8 weeks (± 7 days) until death. For subjects continuing to be imaged at the 
study site, a copy of the imaging and local radiology report will be made available upon request.  Subjects may choose to withdraw from making their imaging available during 
the follow-up period (once they are ‘off-study’).

1. 
Full physical exam is required at Screening. Subsequent physical exams may be symptom-directed. Each PE must include vital signs and weight. 
2. 
Screening imaging must be obtained within 14 days prior to C1D1. A diagnostic CT with contrast must be performed every 6-8 weeks ±7 Days per standard of care until progression or 
intolerable toxicity. SCC patients also require a Brain MRI within 8 weeks prior to C1D1 (does not need to be repeated if SOC imaging performed within window; head CT is allowed if 
MRI is contraindicated). Lesion assessment will be by RECIST v1.1.  In addition to local assessment, upon request, all imaging performed while patient is ‘on-study’ is to be sent to 
EpicentRx within six (6) weeks of procedure visit for independent radiology review. Reference Appendix F for format and shipping instructions.  During the ‘follow-up period’, for 
subjects continuing to be imaged at the study site, a copy of the imaging and local radiology report will be made available upon request.  Subjects may choose to withdraw from making 
their imaging available during the follow-up period (once they are ‘off-study’). 
3. 
Administer Investigator’s Choice Treatment per protocol and approved package insert until progression or intolerable toxicity.  
4. 
For women of childbearing potential (WOCBP), a negative serum or urine pregnancy test is required prior to entering this study. WOCBP and men whose partners are able to become 
pregnant will be asked to use non-hormonal methods of contraception for the entire duration of the study and for up to 90 days after their last dose with RRx-001 and through platinum 
phase. 
5. 
If subject demonstrates progressive disease (PD) during investigator’s choice treatment, treatment will be discontinued and subject will complete End of Study (EOS) visit within 30 days 
of termination of treatment dosing and move into follow-up period.  
6. Follow-up Period begins when patient has PD during investigator’s choice treatment, or discontinues treatment for any other reason. Survival contact will occur via medical record review, 
telephone call or Social Security Death Index every 8 weeks (± 7 days) until death. For subjects continuing to be imaged at the study site, a copy of the imaging and local radiology report 
will be made available upon request.  Subjects may choose to withdraw from making their imaging available during the follow-up period (once they are ‘off-study’).

3. 
Premedication with 10 mg of dexamethasone, or a similar corticosteroid, and a low-dose aspirin (81 mg) or Acetaminophen (500 mg) is required within 2 hours prior to the 
infusion of RRx-001 blood mix. If patient is already receiving dexamethasone or equivalent corticosteroid, premedication with dexamethasone should not be given. 
4. 
Administer carboplatin AUC 5-6 IV on day 1 or cisplatin 60-80 mg/m2 IV on day 1 plus second agent per protocol and approved package insert every 21 days for 4-6 cycles.  
5. 
Only to be performed if subject is a smoker. 
6. 
New tumor biopsy, if feasible, will performed on an optional basis prior to infusion of RRx-001 (baseline) and prior to initial platinum rechallange Day 1 (up to 7 Days prior 
but following discontinuation of RRx-001).  Archival tissue, if available, will be collected at baseline.  For details regarding the processing of samples please refer to the latest 
study lab manual. 
7. 
For women of childbearing potential (WOCBP), a negative serum or urine pregnancy test is required prior to entering this study. WOCBP and men whose partners are able to 
become pregnant will be asked to use non-hormonal methods of contraception for the entire duration of the study and for up to 90 days after their last dose with RRx-001 and

PURPOSE 
One of the biggest obstacles in oncology (cancer treatment) is the almost inevitable 
development of drug resistance, which leaves patients with fewer and fewer options for 
further treatment. The expression “what does not kill me makes me stronger” also applies to 
cancer cells, which are able to actively adapt to the threat of chemotherapy and survive, even 
if they were initially slowed down or stopped by it. The unwritten rule in oncology is ‘once 
resistant, always resistant’, which means that cancer cells are able to ‘remember’ how to 
outsmart particular chemotherapy drugs that they have seen before, and this is why doctors 
tend to abandon them completely in favor other drugs or treatment strategies once resistance 
develops. The purpose of this study is to see if the investigational drug, RRx-001, can 
overturn this unwritten rule, and make chemotherapy that you previously received, and either 
initially responded to or not, have an effect, in other words, sensitize (or resensitize) your 
tumors to chemotherapy. The ability to sensitize or go back to failed chemotherapy may

improve and increase your options and, ultimately, your overall survival. Like the title of this 
study, it is hoped that RRx-001 will have “quadruple threat” activity and resensitize to 
chemotherapy in three forms of lung cancer and ovarian cancer.  
The study has four (4) ‘cohorts;’ one for each of the types of tumors being studied: Small 
Cell Carcinoma (SCC), EGFR Positive Non-Small Cell Lung Cancer (NSCLC), High Grade 
Neuroendocrine Cancer (HGENC) and Resistant or Refractory Epithelial Ovarian Cancer 
(EOC) or Malignant Mixed Mullerian Tumors (MMMT) of the uterus or ovaries. The terms 
“resistant” and “refractory” refer to the lack of responsiveness of the tumor to previous 
therapy such as carboplatin and cisplatin, which is what you received previously to treat your 
cancer. The term “EGFR positive” refers to tumors that carry a mutation or change in the 
EGFR protein, which causes cells to grow uncontrollably. The EGFR protein has 1,210 
amino acids. Amino acids form the building blocks of proteins. EGFR with no mutation at 
amino acid position 790 has a threonine, or T for short; this is called T790M negative cancer, 
which, as a participant on this trial, is what you may have. The amino acid at position 790 in 
EGFR with the T790M mutation is a methionine, or M for short; this is called T790M 
positive cancer. In general, T790M negative cancer is more aggressive than T790M positive 
cancer. 
Figure 1: EGFR T790 mutation. 
You will be treated with the standard of care chemotherapy as well as best supportive care, 
regardless of which study group or cohort you participate in. Subjects in some groups will 
also receive the experimental drug, RRx-001. The timing or schedule of your treatment will 
depend on the cohort you are in. The four cohorts are shown in Figure 2 and described 
below.

Small Cell Carcinoma Cohort: 
Subjects with small cell carcinoma will be assigned randomly or randomized to one of two 
different study groups or “arms”. Subjects assigned to arm 1 will receive a) RRx-001 for 
3 weeks b) followed by cisplatin/carboplatin plus etoposide for up to four cycles c) followed 
by a repeating pattern of RRx-001 given once every week for two weeks and then two three-
week cycles of cisplatin/carboplatin plus etoposide. If at the end of your second cycle of 
cisplatin/carboplatin plus etoposide your tumors are stable to smaller, part “c” repeats. When 
and if your tumors enlarge or get worse your participation on study ends. Subjects assigned 
to arm 2 will receive cisplatin/carboplatin plus etoposide chemotherapy until your tumors 
worsen or progress. You do not get to choose which arm you are assigned to. A computer 
program will choose which arm you are assigned to. Twice as many patients will be 
randomized to arm 1 than arm 2. In other words, there is a 2/3 or 66% chance that you will be 
randomized to arm 1, which is RRx-001 plus chemotherapy and 1/3 or 33% chance that you 
will be randomized to arm 2, which is chemotherapy only. 
Non-Small Cell Lung Cancer (NSCLC) Cohort: 
• If you have EGFR Positive Non-Small Cell Lung Cancer (NSCLC) you will receive 
RRx-001 for 3 weeks followed by cisplatin/carboplatin plus one of the following: 
paclitaxel, albumin bound paclitaxel (this is called nab-paclitaxel or Abraxane), or 
pemetrexed for up to 6 cycles. If, at the end of cisplatin/carboplatin plus another 
chemotherapy agent, your tumors are stable to smaller, you will receive weekly

treatment with RRx-001 until your tumors worsen or progress. At this point, if tumor 
worsening or progression occurs, your participation on study ends.  
High Grade Neuroendocrine Cancer (HGNEC) Cohort: 
• If you have High Grade Neuroendocrine Cancer (HGNEC), you will receive RRx-001 
until your cancer gets worse followed by up to 6 cycles of chemotherapy, which is 
cisplatin/carboplatin plus etoposide. If, at the end of cisplatin/carboplatin plus 
etoposide, your tumors are stable to smaller, you will receive weekly treatment with 
RRx-001 until your tumors worsen or progress. At this point, if tumor worsening or 
progression occurs, your participation on study ends.  
Resistant/Refractory Epithelial Ovarian Cancer (EOC) or Malignant Mixed Mullerian 
Tumors Cohort: 
• Subjects with Resistant/Refractory Epithelial Ovarian Cancer (EOC) or Malignant 
Mixed Mullerian Tumors of the uterus or ovaries will be assigned randomly or 
randomized to one of two different study groups or “arms”. Subjects assigned to arm 
1 will receive a) RRx-001 for 2 weeks b) followed by carboplatin for 3 cycles or 
3 times c) followed by a repeating pattern of RRx-001 for 1 time, carboplatin for 
3 cycles or 3 times, RRx-001 for 1 time, carboplatin for 3 cycles or 3 times etc. until 
your tumors worsen or progress on carboplatin. When and if tumor worsening or 
progression occurs, your participation on study ends. If you are assigned to arm 2, 
you will receive standard of care chemotherapy, which may include carboplatin, 
etoposide, doxil, gemcitabine, vinorelbine, or taxane until your tumors worsen or 
progress.  You do not get to choose which arm you are assigned to. A computer 
program will choose which arm you are assigned to. Twice as many patients will be 
randomized to arm 1 than arm 2. In other words, there is a 2/3 or 66% chance that you 
will be randomized to arm 1, which is RRx-001 plus chemotherapy and 1/3 or 33% 
chance that you will be randomized to arm 2, which is chemotherapy only. 
Cisplatin and carboplatin are a type of platinum-based chemotherapy. These are 
combinations of chemotherapy drugs that contain derivatives of the metal platinum. Another 
example of a platinum-based chemotherapy is oxaliplatin. The combination of cisplatin or 
carboplatin with another chemotherapy agent is called a “platinum doublet”, a term, which is 
used throughout, since the word doublet, refers to “a pair”. 
Approximately 213 patients will be enrolled in this study nationwide. 
A detailed explanation of what will take place during the study is explained below. If you 
have any questions, or if there is any word or procedure(s), which do not make sense, ask the 
doctor or study staff to explain them to you before signing this form (should you wish to 
participate).

DESCRIPTION OF RRX-001 
RRx-001 stimulates immune cells in the tumor called macrophages (literally “big eaters”). 
The job of a macrophage is to engulf or swallow up invaders like bacteria, viruses and even 
cancer cells. The best analogy or comparison for how a macrophage behaves is the famous 
“hungry” character named Pac-Man from the popular arcade game in the 1980s. (Figure 3) 
Like Pac-Man, who is guided through an electronic maze as he “chomps on” yellow dots or 
pellets, the macrophage or “Mac-Man”, in this case, normally travels through the 
bloodstream seeking out and gobbling up hostile or foreign invaders. Unfortunately for the 
patient, however, in advanced cancer the job description of a macrophage is changed from a 
killer of cancer cells to the protector or bodyguard of cancer cells, which explains why they 
are often found in high numbers in the tumor.  
Figure 3. Like Pac-Man that gobbles up yellow energy dots, macrophages normally engulf or swallow 
foreign or hostile invaders except in advanced cancer where their role becomes that of tumor cell 
protectors instead of tumor cell killers.    
 
 
DURATION OF THE STUDY / HOW LONG IS EACH VISIT? 
While you participate in this study, you will receive chemotherapy with or without the study 
drug, RRx-001. The duration of the study depends on which cohort you are in (as described 
above). Each of your study visits can last from approximately 1 to 2 hours.

STUDY PROCEDURES 
Screening  
Screening will last approximately 28 days.  If you agree to be in this research study, you will 
be asked to sign this consent form before the following screening procedures are performed 
to determine if you are eligible for the study.  These screening tests may be performed over 
multiple days and can take between 4 and 8 hours to complete.  
• An occupational, family, social and medical history which will include questions 
about your cancer diagnosis and treatment as well as your health and any past or 
present medical problems and a review of medications, vitamins, and dietary 
supplements you have taken in the past or are taking now. 
• Physical examination 
• Measurement of your height, weight and vital signs (including sitting blood pressure, 
heart rate, breathing rate and oral temperature) 
• Approximately 3 teaspoons of blood will be taken to check your overall health and 
the health of your organs (i.e. liver and kidneys). The blood will be collected from a 
vein in your arm. 
• Approximately 2 teaspoons of blood will be taken for exploratory research studies. 
The purpose of these studies is to look at the health of your heart, blood vessels and 
bones before you start the study. The blood will be collected from a vein in your arm.  
• A pregnancy test if you are female and able to get pregnant.  You must have a 
negative pregnancy test to enter this study and receive RRx-001.  Women, or men 
whose partner is of child bearing potential will be asked to continue the use of 
hormonal or non-hormonal methods of birth control while in the study and for up to 
90 days after withdrawal from the study.  
• CT imaging of your tumor(s). 
o 
The CT scanner is a free-standing machine with a large hole in the center.  You 
will be asked to lie on your back with your arms raised above your head on a 
narrow table that slides into the hole.  A dye may be injected into a peripheral 
vein (veins in the arms, feet, legs and hands that supply oxygenated blood to the 
body) to better evaluate certain diseases and organs.  The radiologist will decide 
if this is necessary.  Tell the technician or radiologist if you have any allergies to 
contrast dye or have had difficulty with prior CT scans.  It is very important that 
you remain still throughout the exam and hold your breath when asked.  This 
will allow for better images.  The actual scan time is usually about two minutes, 
although the entire procedure may take up to 2 hours. 
• If you have SCC, you will also have a CT or MRI of the brain 
• Tumor Biopsy: If you and the doctor feel that it is in your best interest, based on your 
health and the current status of your disease, we would like to offer you the ability to 
get your tumor biopsied prior to starting any study medication. The procedure offered

would be a biopsy of your tumor and/or collection of archival tumor tissue from a 
previous biopsy of your tumor. If you and the doctor decide that it is in your best 
interest to undergo a biopsy of your tumor, all risks will be explained to you before 
the procedure and trained and credentialed staff will perform the procedure.  The risks 
of this procedure include, but are not limited to: pain, bleeding, infection and hospital 
admissions.  
A biopsy and/or collection of archival tissue is not required for your participation in this 
research study.  There may be no direct benefit to you from collection of archival tissue 
and/or a biopsy; however, the doctor and/or researchers may learn more about your 
tumor(s) and how to treat them.  
Study Treatment 
If the exams, tests and procedures show that you can be in the study and you choose to take 
part, then you will be assigned to one of the four treatment cohorts depending on the type of 
cancer that you have. In addition to chemotherapy treatment and/or the study drug, RRx-001, 
, you will also receive best supportive care which includes treatments to help manage side 
effects and symptoms of cancer.  This is an open label study, which means you will know the 
names of the drugs that you receive.  
You will be scheduled to return to the study site for the Day 1 visit of the first (1st) period. 
Additional study visits will occur weekly. You will be asked to continue the use of hormonal 
or non-hormonal methods of birth control and to return to all required clinic visits during the 
entire treatment part of study and for 90 days following completion of therapy. 
About RRx-001 treatment 
Depending on what arm you are assigned to, you may receive the study drug, RRx-001. RRx-
001 is given once a week through a vein in your arm or through a catheter or ‘port’ in your 
chest. When you come into the clinic for treatment, the doctor or study staff will withdraw 
approximately 12 mL of your own blood through a vein in your arm or through a catheter or 
‘port’ in your chest into a syringe containing 4 mg (2 mL) of RRx-001; for comparison, a 
teaspoon is equal to 5 mL, therefore 12 mL of blood is about 2 ½ teaspoons in volume. Using 
an investigational device called the eLOOP, the blood will be mixed with the study drug, 
RRx-001, and re-infused through a vein in your arm over a period of up to 30 minutes.  This 
process is called “autohemotransfusion.” The handling of blood by the study staff at 
[INSERT SITE] will be done according to the Institutional Standard of Care guidelines at 
[INSERT SITE]. Approximately 30 minutes before the infusion of RRx-001, you will receive 
pre-medications, such as dexamethasone, or another corticosteroid, and a Baby Aspirin (81 
mg) or Acetaminophen (500 mg), to help with any pain associated with the infusion, although 
this is unlikely. Sometimes it may be necessary to slow down the infusion and administer 
RRx-001 over a longer time. Based on any side effects you are experiencing, dose 
interruptions and/or dose reductions are allowed if the doctor feels that it is in your best 
interest to do so. When you do leave the clinic for the day, you should be accompanied 
by a caregiver that can carefully observe your physical condition and symptoms 
overnight and call the hospital if necessary.

• You will receive RRx-001 once a week for 3 weeks.  
• You will have a CT scan at the end of week 3. 
 
Period 2: Platinum Chemotherapy 
During Period 2, you will receive the following platinum-based chemotherapy regimen: 
1) One of the following platinum agents:  
a) Cisplatin will be given through a vein in your arm 60-80 mg/m2 on day 1 every 
3 weeks. 
b) Carboplatin will be initially dosed through a vein in your arm at an area under the 
curve (AUC) or concentration of 5-6 on day 1 every 3 weeks. 
2) Second agent to be combined with the platinum-based agent 
a) Etoposide will be initially dosed at 80-100 mg/m2 days 1-3 every 3 weeks 
You will also receive best supportive standard of care to help manage any side effects 
associated with your disease or the treatments you receive.   
During Period 2, the doctors and/or study staff will perform the following tests and/or 
procedures:

• A physical exam and measurement of your height, weight and vital signs (to include 
your sitting blood pressure, heart rate, breathing rate and oral temperature). 
• You will be asked about the medications you are currently taking (‘Concomitant 
Medications’) and any side effects you are experiencing. 
• Approximately 9 teaspoons of blood will be taken at the beginning of your platinum 
doublet treatment for exploratory research studies. The purpose of these studies is to 
examine and analyze the genes, proteins, and cells found in the blood. The blood will 
be collected from a vein in your arm.  
• Approximately 2 teaspoons of blood will be taken on the first day of your last cycle 
of platinum doublet treatment for exploratory research studies. The purpose of these 
studies is to look at the health of your heart, blood vessels and bones before you start 
the study. The blood will be collected from a vein in your arm.  
• Approximately 2 teaspoons of blood will be taken weekly to check your overall 
health and the health of your organs (i.e. liver and kidneys) 
• You will receive a CT scan every 2 cycles during treatment with platinum doublets. 
Therefore, this will happen at the end of Cycle 2, or (6) weeks after your first day 
receiving platinum chemotherapy, and at the end of Cycle 4. 
Period 3: Maintenance 
You will receive a repeating pattern of RRx-001 for 1 time, carboplatin for 2 cycles or 
2 times, RRx-001 for 1 time, carboplatin for 2 cycles or 2 times etc. until your tumors worsen 
or progress on carboplatin. When and if tumor worsening or progression occurs, your 
participation on study ends. 
During Period 3, the doctors and/or study staff will perform the following tests and/or 
procedures: 
• A physical exam and measurement of your height, weight and vital signs (to include 
your sitting blood pressure, heart rate, breathing rate and oral temperature). 
• You will be asked about the medications you are currently taking (‘Concomitant 
Medications’) and any side effects you are experiencing. 
• Approximately 2 teaspoons of blood will be on Day 1 of each RRx-001 and each 
platinum cycle to check your overall health and the health of your organs (i.e. liver 
and kidneys) 
• You will receive a CT scan every 2 platinum chemotherapy cycles. Therefore, this 
will happen at the end of Cycle 2, or (8) weeks after starting period 3.  This will 
continue every eight (8) weeks, or two (2) cycles, for as long as you continue on 
study.

GENERAL DISCUSSION OF GENETICS 
EpicentRx, Inc. will be responsible for deciding how your samples will be used. Blood taken 
from you may be used to establish products that could be patented and licensed.  There are no 
plans to provide you with financial compensation should this occur.  This blood and tissue 
and its derivatives may have significant therapeutic or commercial value.  You consent to 
such uses.  Your study doctor has no personal or financial interest in this research. If you 
decide later that you do not want the specimens collected from you to be used for future 
research, you may tell this to [INSERT PI], who will use his/her best efforts to stop any 
additional studies.  However, in some cases, such as if your specimens have already 
undergone testing, it may be impossible to locate and remove the data collected from those 
tests because the data collection is no longer linked to you directly. 
EpicentRx, Inc. will be responsible, have control over the long-term storage location and will 
keep your DNA specimen and/or the information derived from it indefinitely. 
There will be no direct benefit to you from this study since you will not be provided with any 
results or information regarding your DNA test. The investigator, however, may learn more 
about SCC, NSCLC, HGNEC, or EOC/MMMT. 
Instances are known in which a subject in research has been required to furnish genetic 
information as a precondition for in applying for health insurance and/or a job. Participation 
in this study does not mean that you have had genetic testing. Genetic testing means having a 
test performed and the results provided to you and your doctor. If you are interested in 
having genetic testing performed you should consult your doctor, as some commercial tests 
are available. Your doctor can provide you with the necessary information to determine if 
such a test would be appropriate for you.

Some people involved in genetic studies have felt anxious about the possibility of carrying an 
altered gene that they could possibly pass on to their children.  Even though we will do our 
best to keep your information confidential, there is the possibility that your genetic risk for 
certain diseases is accidently divulged to the wrong source, if that happens you might be 
discriminated against obtaining life or health insurance, employment or ability to adopt 
children. 
Federal and State laws generally make it illegal for health insurance companies, group health 
plans, and most employers to discriminate against you based on your genetic information. 
This law generally will protect you in the following ways:  
a) Health insurance companies and group health plans may not request your genetic 
information that we get from this research.  
b) Health insurance companies and group health plans may not use your genetic 
information when making decisions regarding your eligibility or premiums.  
c) Employers with 5 or more employees may not use your genetic information that we 
get from this research when making a decision to hire, promote, or fire you or when 
setting the terms of your employment. 
Be aware that these laws do not protect you against genetic discrimination by companies that 
sell life insurance, disability insurance, or long-term care insurance. 
 
RISKS OF PARTICIPATION 
Participation in this study may involve some added risks or discomforts.  While you are on 
this study, you are at risk for the side effects listed below.  You should discuss these with 
your doctor.  There may also be other side effects that we cannot predict.  Other drugs will be 
given to make side effects less serious and uncomfortable.  Many side effects go away 
shortly after the study drug is stopped, but in some cases, side effects may be serious, long 
lasting, and may even cause death. 
There may be other risks associated with participation in this study that are currently 
unforeseeable. 
In the initial clinical trial of RRx-001 in which 25 patients with various different types of 
cancers received RRx-001 intravenously, the main side effect in 84% of patients was 
temporary pain and/or a stinging, burning sensation at the injection site in the forearm and 
along the length of the vein as well as swollen veins (vasodilation).  Pain and swollen veins, 
when they occurred, lasted during the entire time of infusion of RRx-001 and, generally, both 
of these side effects went away almost immediately (within minutes) of stopping the infusion 
of RRx-001.  
This discomfort experienced by patients during infusion was when the drug was injected 
directly into a vein and now the administration process has been updated to mix with blood

prior to infusion, eliminating all or most of the discomfort associated with direct IV infusion.  
To minimize the risk of discomfort, you will receive a pain reliever (Baby Aspirin or 
Acetaminophen) and anti-inflammatory medications (corticosteroids) before the infusion. 
Your study doctor may also slow down the infusion.

There were no serious side effects that were thought to be related to RRx-001 during the 
initial study which were life-threatening or required hospitalization of the patient. 
During a recent study of RRx-001 in combination with irinotecan, an FDA-approved 
anticancer agent, one RRx-001-treated patient died on study due to low blood counts and 
infection (sepsis); which can occur with irinotecan. While it is unlikely that RRx-001 
contributed to these side effects, based on its overall favorable safety track record, it is also 
impossible to definitely rule it out since this was the first such treated patient. It is also 
important to note that by choosing to participate in this study, you will not be receiving 
combination therapy with RRx-001 plus irinotecan. 
Because RRx-001 is an investigational drug and not a lot of patients have received the drug, 
not all of the side effects are known at this time. It is not known if additional side effects will 
be seen with this drug. Also, it is important to be aware that, even though precautions and 
prevention practices are in place, treatment of your blood with RRx-001 outside of the body 
before it is returned to you is a risk factor for bacterial contamination of the blood. The 
administration of contaminated blood may possibly lead to life threatening or fatal infections. 
For this reason you will be watched closely for known and other unknown, possibly serious 
side effects.

side effects may occur more frequently, such as decreased platelet counts, hair loss, 
decreased kidney function, injection site reactions, intestinal obstruction, gastrointestinal 
bleeding, and formation of blood clots in deep veins and serious skin reactions. 
Complications of some of the above side effects may lead to life-threatening events such as 
infections, kidney failure, bleeding, and possibly death. There is slight risk of severe allergic 
reaction to the drug, which may be life threatening. There is always a risk involved in taking 
a new drug but every precaution will be taken to minimize the risk.

• Anemia (decrease in red blood cells 
in the blood), which may result in 
symptoms such as fatigue or 
shortness of breath 
• Leukopenia (decrease in white blood 
cells in the blood, including low 
levels of neutrophils or lymphocytes), 
which may affect your body’s ability 
to fight infections 
• Abnormal liver tests (may suggest 
liver damage) 
• Protein or blood in urine 
• Hyperglycemia (high blood sugar) 
• Electrolyte loss (low blood calcium or 
magnesium) 
• Stomatitis (inflammation of the 
mouth and lips) 
• Abnormal kidney test (may suggest 
kidney damage) 
• Rash 
• Thrombocytopenia (low platelet 
count, which may make you more 
likely to bruise or bleed) 
• Dyspnea (shortness of breath)

Less Likely 
• Injection site reactions 
• Allergic reaction (breathing 
difficulty) 
Rare, but 
serious 
• Pulmonary toxicity, including 
interstitial pneumonitis, pulmonary 
fibrosis, pulmonary edema, and adult 
respiratory distress syndrome 
(ARDS), which can lead to fatal 
respiratory distress 
• Capillary leak syndrome (leakage of 
fluids from blood vessels to tissues) 
• Posterior reversible encephalopathy 
syndrome (possible headache, 
confusion, seizure and/or vision loss, 
may suggest brain damage) 
• Hemolytic uremic syndrome 
(condition associated with decrease in 
red cells, platelets and kidney 
function), which can require dialysis 
or lead to fatal kidney failure 
• Serious hepatotoxicity, including 
liver failure and death 
 
Gemcitabine is known to increase toxic side effects of radiation therapy, and should not be 
used within a week before or after radiation. Gemcitabine causes birth defects and is toxic to 
embryos and fetuses in mice and rabbits. Gemcitabine can cause fetal harm if taken while 
pregnant.

Other Study-Related Risks: 
Allergic Reactions:  As with any drug, there is the chance of an allergic reaction, which may 
include difficulty breathing, rash, flushing, weakness, dizziness, lightheadedness, and 
swelling. 
Intravenous (IV) Injection Side Effects:  If the drug leaks from the vein the shot is given 
into, it may cause skin irritation at the needle site. 
Risks of blood draws:  There is a risk of discomfort or pain, bleeding, swelling and a small 
arm bruise and swelling when blood is drawn.  Rarely, a clot or infection may occur at the 
site of the blood draw.  Some people also become faint, dizzy, or light-headed during or 
immediately after the blood draw.

Protocol Dated: July 20, 2018 
Version: August 20, 2018 
Risks and Side Effects of a Central Line:  Subjects may be required to have placement of a 
“central line.”  A central line is a catheter that is placed under your skin and into a large vein.  
It will allow easy administration of the chemotherapy drugs.  Risks of placement of a central 
line include bleeding or lung collapse when the catheter is placed, as well as inflammation at 
the site of the catheter, and infection. 
Reproductive Risks:  You should not become pregnant or father a baby while on this study 
and for a period of time following your last dose of RRx-001 because the drugs in this study 
can possibly affect a fetus and cause serious birth defects.  Women should not breastfeed a 
baby while on this study.  It is important you understand that you need to use birth control 
while on this study.  If you are female and capable of childbearing, a pregnancy test will be 
done before the study begins in order to be as sure as possible that you are not pregnant.  
Your participation requires that you use hormonal (such as birth control pills) or non-
hormonal contraception methods (such as abstinence, diaphragm, condom, or intrauterine 
device) to prevent pregnancy for the duration of the study and for 90 days following your last 
dose of RRx-001.  Ask about counseling and more information about preventing pregnancy. 
Risks from CT Scans:  During your participation in this research study, you will be exposed 
to radiation from scheduled CT scans.  The total exposure resulting from these imaging 
studies is calculated to be approximately 117 mSv each year.  This amount is more than you 
would receive from one year of natural exposure in the [INSERT CITY AND STATE OF 
CLINIC] area, which is approximately 1.6 mSv.  Cumulative exposure from radiation may 
increase your risk of developing certain types of cancer in the future. 
The principal investigator for this research study has determined and verified that all of the 
CT scans prescribed for this study would typically be performed as part of the standard 
medical care required to adequately monitor your current illness.  You will have a CT scan of 
your chest, abdomen and pelvis at Screening and every 6 weeks thereafter during period 1 of 
this study when you’re receiving the study drug, RRx-001, and every 6 weeks once you’ve 
started period 2.  Additional imaging may be performed if clinically indicated. If you are 
especially concerned with radiation exposure, or you have had a lot of x-rays or imaging 
scans already, you should discuss this with the principal investigator for this study, [INSERT 
PI], or your regular doctor. 
Risks of IV Contrast: As part of this study a CT scan may be done. There may be some 
reactions related to the contrast dye used in CT scans. Contrast dye is usually administered 
when you get a CT scan. Some people may develop hives and itching or other allergic 
symptoms from this dye, swelling of the heart, cramps of the voice box, breathing distress 
caused by narrowing of the airways in lungs, low blood pressure, with loss of consciousness, 
and in rare cases, severe loss of blood and fluids leading to shock and death, fainting, 
seizures, and irregular heartbeats.  In addition, if you have low kidney function, this dye can 
temporarily or permanently decrease your kidney function.  
Risks of bronchoscopy: If you provide consent, biopsies of your tumor(s) may be performed. 
As part of this procedure, a bronchoscopy may be performed. This involves using a very 
small camera to look inside the tubes (“bronchi”) within your lungs. Although slight

Version: August 20, 2018 
(occurring in about 5-8% of patients), there are some risks / complications associated with 
this procedure. These include:  
• Pneumothorax – This is when air or gas builds up in the space between the lung and 
the chest. This is often called “collapsed lung” and can result in difficulty breathing. 
• Hypoxemia – This is when not enough oxygen is supplied to the blood circulating in 
your body causing the lungs to potentially work harder to increase the supply of 
oxygen. 
• Hemorrhage – This is when some blood escapes from the veins and arteries in your 
body due to a cut, puncture or rupture, resulting in external (outside your body) or 
internal (inside your body) bleeding. 
 
Risks of Loss of Confidential Information: There is also a small risk that information from 
your health records will be released to an unauthorized party. We will do our best to make 
sure that your personal information will be kept private.  The chance that this information 
will be given to someone else is very small. An identification code assigned by the study 
team to each patient will be used in place of your name to protect your identity when 
reporting trial-related data. 
BENEFITS OF PARTICIPATION 
If you agree to take part in this study, there may not be direct medical benefit to you.  Others, 
however, may benefit from the information learned from this research study, and the 
investigators may learn more about RRx-001. 
ALTERNATIVES TO PARTICIPATION 
If you choose not to take part in or stop participating in this research study, there may be 
other treatments.  Refusal to take part in this study will not cause penalty or loss of benefits 
to which you are otherwise entitled. 
You do not have to participate in this study to receive treatment for your cancer.  Other 
possible treatments could include treatment with other drugs or drug combinations, 
participation in other research studies, or supportive care only (no cancer treatment).   
Please talk to your doctor about these and other options. 
COSTS/COMPENSATION 
The study drug, RRx-001, will be supplied at no cost while you take part in this study. The 
cost of getting the study drug, RRx-001, ready is also provided at no cost.  The study drug 
administration is not paid for by the study sponsor, so you or your health plan/insurance 
company may have to pay for this.

EpicentRx RRx-001-211-01, Amendment 10 
Protocol Dated: July 20, 2018 
Version: August 20, 2018 
It is possible the study drug, RRx-001, may not continue to be supplied while you are on the 
study. Although not likely, if this occurs, your study doctor will talk to you about your 
options. 
You and/or your health plan/insurance company will need to pay for all of the other costs of 
caring for your cancer while in this study, including the costs of tests, procedures, or 
medicines to manage any side effects, unless you are told that certain tests are supplied at no 
cost.  Before you decide to be in the study, you should check with your health plan/insurance 
company to find out exactly what they will pay for.  
Examples of procedures and drugs that may be billed include the following: routine clinic 
visits, routine laboratory tests, CT imaging, pre-medications (baby aspirin/acetaminophen 
and dexamethasone), and FDA-approved chemotherapy with platinum-based doublets. 
There will be no payment to you for participating in this study.   
The sponsor, EpicentRx Inc., is paying the institution, [INSERT SITE] to do this study. 
COMPENSATION FOR RESEARCH-RELATED INJURY 
If you are injured as a direct result of being in this study, treatment will be available. The 
costs of such treatment will be covered by the [INSERT SITE] or the study sponsor, 
EpicentRx Inc., depending on a number of factors. The [INSERT SITE] and the study 
sponsor, EpicentRx Inc., do not normally provide any other form of compensation for injury. 
You may call the [INSERT SITE] Human Research Protections Program Office at (xxx) xxx-
xxxx for more information about this, to inquire about your rights as a research subject, or to 
report research-related problems. 
VOLUNTARY PARTICIPATION 
Participation in this study is entirely voluntary.  If you choose not to participate or wish to 
withdraw your consent to participate in these study procedures at any time, it will in no way 
affect your regular treatments or medical care at this institution or loss of benefits to which 
you are entitled. 
You will be informed of any new findings that might affect your willingness to continue 
participating in the study. 
The study doctor may stop your participation in this study without your consent.  If you have 
any side effects that are very serious or if you become ill during the course of the research 
study you may have to drop out even if you would like to continue.  The study doctor will 
make the decision and let you know if it is not possible for you to continue. The decision that 
is made is to protect your health and safety, or because it is part of the research plan that 
people who develop certain conditions or do not follow the instructions from the study doctor 
may not continue to participate.  In addition, EpicentRx Inc. may end your participation in 
the study at any time without your consent. 
If you withdraw from the study for any reason, you must notify your study doctor, 
[INSERT PI] at (xxx) xxx-xxxx.  You will be asked to return to the clinic so that the study

Information on Alternative Treatments After Progression on RRx-001 
Please read below and think about your choice. The purpose of this study is to find out 
whether treatment with RRx-001 will make your tumor sensitive to retreatment with 
platinum-doublet chemotherapy.  However, it is important to realize that an existing FDA 
therapy may be available for your cancer and, if it is available, what are the potential benefits 
and common side effects of that therapy. The table below shows what FDA therapies may be
