BACKGROUND AND RATIONALE 
 
1.1 
T-Acute Lymphoblastic Leukemia / Lymphoblastic Lymphoma 
 
T-acute lymphoblastic leukemia (T-ALL), and the related disease T-lymphoblastic 
lymphoma (T-LBL), is an aggressive malignant neoplasm of the bone marrow. It 
accounts for 20% of all cases of ALL and is more common in adults than children [1]. 
With the use of modern therapy, 90% of people diagnosed with T-ALL and T-LBL will 
achieve first remission with 5-year overall survival (OS) of 48% [1]. Despite 
improvements to first-line therapy, the outcome of adult ALL (B-cell and T-cell 
subtype) after relapse, and in patients with failure to standard induction therapy, is 
extremely poor with 30% of the patients responding to first salvage therapy and long-
term survival of only 10%[2-4]. These relapsed patients will have a chance of cure if 
they receive an allogeneic hematopoietic cell transplant (alloHCT) after first salvage 
therapy; however, only a small fraction of them will be candidates for such therapy 
due to refractory disease at time of relapse, and for those patients who fail the first 
salvage therapy, the outcome is dismal [5]. Novel therapies for ALL (including 
blinatumomab, inotuzumab, and CD19 chimeric antigen receptor T cells) have 
demonstrated significant promise in ALL but target only antigens specific to patients 
with B-ALL.[6] Therefore, novel therapies for patients with relapsed/refractory T-
ALL/LBL represent an unmet clinical need.  
 
1.2 
Nelarabine for Relapsed / Refractory T-ALL/LBL 
 
Nelarabine is a pro-drug of the nucleoside analog ara-G. In trials of patients with 
relapsed or refractory T-ALL/LBL, nelarabine results in a complete remission (CR) 
rate of 15-30% [7, 8]. One group reported on 126 patients treated with the regimen 
of 1.5 g/m2 per day on Days 1, 3, and 5 in multiple 21-day cycles [8]. Forty-five 
patients achieved CR (36%) and 12 a partial remission (PR). Of the CR patients, 80% 
were able to proceed to alloHCT. The OS was 24% at 1 year and 11% at 6 years, with 
allo-HCT patients achieving an OS of 31% at 3 years. Nelarabine was granted 
accelerated approval by the FDA for treatment of patients who have been refractory 
to or relapsed after two chemotherapy regimens based on CR rates from two single 
arm phase 2 studies [9].  CR rates with single agent nelarabine lag behind what is 
already achieved with the use of immunotherapy alone in patients with relapse B-
ALL. Thus, optimal combination regimens with nelarabine need to be evaluated.  
 
1.3 
Critical Role of CXCR4 and CXCL12 Interaction in T-ALL 
 
CXCL12 (also known as stromal-derived factor-1, SDF-1) is a chemokine 
constitutively produced at high levels by bone marrow stromal cells. CXCL12, through 
interaction with its major receptor CXCR4, regulates many aspects of T cell biology, 
including proliferation, survival, and migration [10-13]. CXCR4 is expressed on most 
malignant hematopoietic cells, including T-ALL. Two recent studies provide strong 
preclinical evidence that CXCR4 signaling provides key signals that are required for T 

Protocol Version: 01/17/23, Amendment 2 
 
Page 8 of 33 
ALL cell survival and expansion [14, 15]. Of particular interest, data suggest that 
CXCR4 signaling is required for T-ALL leukemia-initiating activity. Relevant to this 
proposal, treatment with a CXCR4 antagonist reduced the growth of primary human 
T-ALL in a xenotransplant mouse model. Of note, prior studies also have implicated 
CXCR4 signaling in resistance to chemotherapy [16]. A clinical trial investigating 
CXCR4 inhibition in combination with chemotherapy in patients with relapsed acute 
myeloid leukemia showed a higher response rate than expected in patients with 
advanced disease [17]. Based on these observations, we hypothesize that the addition 
of an inhibitor of CXCR4 to chemotherapy will improve the response rate of patients 
with T-ALL.  
 
1.4 
Study Agent: BL-8040 
 
BL-8040 (developed by BioLineRx Ltd., formerly developed by Biokine Therapeutics 
and known as BKT140) is a novel selective inhibitor of the CXCR4 chemokine 
receptor. BL-8040 is a 14-residue, cyclic, synthetic peptide capped with an aromatic 
ring. It binds and inhibits the CXCR4 chemokine receptor with high affinity (IC50 0.5-
5.2 nM) and has been shown to be a specific antagonist of CXCR4 both in vitro and in 
vivo studies and to have a slow dissociation rate from the receptor [18, 19]. Compared 
to other inhibitors of CXCR4 such as plerixafor, BL-8040 is a more potent 
hematopoietic stem cell mobilizing agent and also induces apoptosis as a single agent 
against malignant hematopoietic cells [20]. Therefore, we propose to conduct a pilot 
study of BL-8040 in combination with nelarabine in adults with relapsed or 
refractory T-ALL/LBL. Two clinical trials with BL-8040 have been reported so far 
with promising safety and efficacy [21, 22]. In both studies the most common adverse 
events (AEs) seen are injection site reactions and systemic reactions: hives, pruritus, 
flushing, chills, rash and urticaria. 
 
1.5 
Study Rationale 
 
The outcomes of patients with relapsed/refractory T-ALL/LBL are dismal and the 
only chance of cure is to undergo alloHCT soon after achieving second CR. However, 
with current strategies, only a small percentage of patients will respond to first 
salvage therapy. Recent data provide strong evidence that CXCR4 signaling plays a 
major role in T-cell leukemia cell maintenance and leukemia initiating activity, and 
targeting CXCR4 signaling in T-ALL cells reduces tumor growth in an animal model. 
Thus, we propose the addition of BL-8040 to nelarabine as a salvage therapy for 
patients with relapsed/refractory T-ALL/LBL. Our hypothesis is that such strategy 
will result in a higher CR rate than nelarabine alone without an increase in toxicity so 
that a higher percentage of patients with relapsed/refractory T-ALL/LBL will 
respond and proceed to alloHCT without delay.

TREATMENT PLAN 
 
7.1 
Agent Administration 
 
Cycle 1 
BL-8040: 1.5 mg/kg subcutaneous daily from Day 1 to Day 6.  
Nelarabine: 1,500 mg/m2 intravenously over 2 hours on Days 2, 4 and 6. 
 
 

Protocol Version: 01/17/23, Amendment 2 
 
Page 14 of 33 
Cycle 2-4 
BL-8040: 1.5 mg/kg subcutaneous daily from Day 1 to Day 5.  
Nelarabine: 1,500 mg/m2 intravenously over 2 hours on Days 1, 3 and 5. 
 
On days that both drugs are administered, BL-8040 should be administered 
approximately 2-4 hours prior to nelarabine.  Treatment may be repeated every 21 
days for up to 4 cycles or until disease progression, whichever occurs first.  
 
7.2 
Dose Modifications 
 
The doses of nelarabine and BL-8040 will be calculated based on actual body weight. 
Nelarabine should be discontinued for grade ≥ 2 neurological events. BL-8040 should 
be held for a peripheral blood blast count which exceeds 50,000/mcL and upon 
clinical signs of leukostasis. Skipped doses of BL-804 will not be made up.  No other 
dose modifications are permitted for either BL-8040 or nelarabine. Subsequent cycles 
of therapy should be delayed for clinically significant grade ≥ 3 nonhematologic 
toxicity until resolution to grade ≤ 2.  For subjects achieving a morphologic leukemia 
free state (<5% BM blasts, no circulating lymphoblasts), nelarabine should be delayed 
until neutrophil recovery (ANC > 1,000/mcL). If dose delay is required beyond 28 
days, the subject will be permanently discontinued from study treatment.  
 
7.3 
Response Evaluation 
 
For patients with marrow disease at baseline, a bone marrow biopsy and aspiration 
should be performed after every cycle until clearance of marrow leukemic blasts 
(<5%) is documented.    
 
For patients with measurable extramedullary disease at baseline, a CT scan should be 
performed at the end of Cycle 1, 2 and 4 for response assessment.  A PET/CT scan 
should be performed to confirm any response.   
 
7.4 
Supportive Care 
 
Hydroxyurea 
and/or 
leukapheresis 
is 
permitted 
to 
prevent 
or 
treat 
hyperleukocytosis. Concurrent intrathecal chemotherapy is permitted during 
treatment either as prophylaxis or treatment for CNS involvement of leukemia.  
 
In case of TLS, subjects should be hydrated vigorously (urine output and fluid input 
should be monitored).  Allopurinol, rasburicase, or any other treatment according to 
institutional practice should be considered. 
 
Premedication and/or treatment with steroids and/or antihistamines is 
recommended in order to reduce the systemic reactions with BL-8040.  Analgesics or 
local anesthetics (e.g. EMLA®) may be used for injection site pain management. 
 

Protocol Version: 01/17/23, Amendment 2 
 
Page 15 of 33 
Supportive care including the use of antiemetics, antibiotic prophylaxis, and colony 
stimulating factors will be at the discretion of the treating physician and guided by 
institutional practices.  
 
7.5 
Women of Childbearing Potential 
 
Women of childbearing potential should remain on birth control for 30 days after the 
last day of treatment, and men with partners who are of childbearing potential should 
use birth control for 90 days.  Birth control method must be considered highly 
effective (hormonal or barrier method of birth control, abstinence). 
 
Non-childbearing potential is defined as: 
• ≥ 45 years of age and has not had menses for > 2 years 
• Amenorrheic for > 2 years without a hysterectomy and oophorectomy and a 
FSH value in the postmenopausal range upon pretrial (screening) evaluation 
• Post-hysterectomy, 
oophorectomy, 
or 
tubal 
ligation. 
Documented 
hysterectomy or oophorectomy must be confirmed with medical records of 
the actual procedure or confirmed by an ultrasound.  Tubal ligation must be 
confirmed with medical records of the actual procedure. 
 
7.6 
Duration of Treatment 
 
If the constraints of this protocol are considered to be detrimental to the patient’s 
health and/or the patient no longer wishes to continue protocol therapy, the protocol 
therapy must be discontinued and the reason(s) for discontinuation documented. All 
decisions regarding future therapy for both responding and refractory patients will 
be at the discretion of the treating physician.  
 
Patients will be considered to have completed treatment upon completion of 4 cycles, 
disease progression, or administration of additional antileukemic therapy including 
alloHCT.  All decisions regarding future therapy for both responding and refractory 
patients will be at the discretion of the treating physician.   
 
7.7 
Follow-up 
 
Patients removed from treatment for unacceptable adverse events will be followed 
until resolution or stabilization of the adverse event. Patients will be followed for a 
minimum of 30 days post-treatment for adverse events. Patients achieving a CR or 
CRi will be followed for disease relapse and/or death every 3 months following 
completion of treatment for a maximum of 2 years.  
 
7.8 
Removal from Study 
 
Patients may be removed from the study at the discretion of the treating physician 
and / or Principal Investigator for any of the following reasons: 

Protocol Version: 01/17/23, Amendment 2

8.0 
RESPONSE EVALUATION 
 
The following criteria will be used to assess the response to treatment. 
 
Complete Remission (CR): A CR requires the following: an absolute neutrophil count (segs 
and bands) > 1,000/mcL, no circulating lymphoblasts, platelets ≥ 100,000/mcL; and < 5% 
marrow leukemia blast cells with complete disappearance of all measurable disease as 
confirmed by physical examination, CT scan and/or FDG-PET (Deauville criteria score of 1, 
2, or 3). 
 
Morphologic complete remission with incomplete blood count recovery (CRi): Defined 
as CR with the exception of neutropenia < 1,000/mcL or thrombocytopenia <100,000/mcL.  
 
Partial Remission (PR): A PR requires all of the CR criteria except that marrow may still 
contain 5-25% leukemia blast cells. An absolute neutrophil count (segs and bands) ≥ 
1000/mcL, no circulating blasts, and platelets > 100,000/mcL are requires as for a CR. For 
patients with measurable disease, a reduction of 50% or more in the sum of the products of 
the perpendicular diameters of all measurable lesions compared with pretreatment 
measurements and with no new or enlarging lesions.  
 
Refractory Disease: Failure to achieve a CR/CRi with persistence of leukemia cells after 
treatment. 
 
Relapsed Disease: The reappearance of unequivocal leukemia blasts cells in the blood or 
the bone marrow (>5%) or in any other extramedullary site after a CR/CRi. 
 
Time to neutrophil recovery: Defined as the date of the first dose of study drug to the date 
that the absolute neutrophil count is >1,000/mcL. 
 
Time to platelet recovery:  Defined as the date of the first dose of study drug to the date 
that the platelet count is >100,000/mcL in the absence of platelet transfusions. 
 
Overall survival: Defined as the date of first dose of study drug to the date of death from 

Protocol Version: 01/17/23, Amendment 2 
 
Page 17 of 33 
any cause. 
 
Event-free survival: Defined as the interval from the date of first dose of study drug to date 
of treatment failure, recurrence, or death due to any cause. 
 
Duration of remission: Defined as the interval from the date CR/CRi is documented to the 
date of recurrence. 
 
Relapse-free survival: For patients achieving a complete remission, defined as the interval 
from the date of first documentation of CR/CRi to the date of recurrence or death due to any 
cause.

PHARMACEUTICAL INFORMATION 
 
9.1 
BL-8040 
 
Mechanism of action: 
BL-8040 (developed by BioLineRx Ltd., formerly developed by Biokine Therapeutics 
and known as BKT140) is a novel selective inhibitor of the CXCR4 chemokine 
receptor. BL-8040 is a 14-residue, cyclic, synthetic peptide capped with an aromatic 
ring. It binds and inhibits the CXCR4 chemokine receptor with high affinity (IC50 0.54-
5.2 nM) and has been shown to be a specific antagonist of CXCR4 both in vitro and in 
vivo studies and to have a slow dissociation rate from the receptor.  
 
Availability 
BL-8040 drug product is formulated as a sterile and non-pyrogenic lyophilized 
powder containing 73mg/vial BL-8040 (free base, on dry basis). Reconstitution 
instructions will be provided separately in a pharmacy manual. Lyophilized BL-8040 
is filled and packed in clear Type I glass vials (DIN 6R) with 20 mm rubber stoppers 
and sealed with 20 mm aluminum caps. BL-8040 can be injected within 24 hours after 
reconstitution if stored in the refrigerator, 5°C ± 3°C (36 to 46°F). 
 
Storage & Stability 
Vials of BL-8040 for injection should be stored in the refrigerator (5°C ±3°C) in their 
original package, protected from light. BL-8040 is to be injected within six hours after 
reconstitution. 
 
Administration 
BL-8040 will be administered by slow SC injection. Injection sites should be rotated 
daily. 
 
Toxicity 
Preclinical Studies 
The nonclinical development of BL-8040 has encompassed a large number of 

Protocol Version: 01/17/23, Amendment 2 
 
Page 18 of 33 
pharmacodynamic, pharmacokinetic (PK), safety pharmacology, and single and 
repeated dose toxicity studies.  
 
BL-8040 exhibits CXCR4-dependent selective cytotoxicity toward malignant cells 
both in vivo and in vitro and induces apoptotic cell death in cancer cells [20, 23-25][3–
6]. BL-8040 leads to phospharidylserine externalization, decreased mitochondrial 
membrane potential, caspase activation, subsequent sub-G1 arrest and DNA double-
stranded breaks in leukemic and Multiple Myeloma cells [20]. These effects were 
shown to be specific; BL-8040 did not affect the viability of human keratinocytes and 
normal human hematopoietic cells [20]. This property of direct apoptotic effects on 
top of the mobilization capacity, distinguishes BL-8040 from other CXCR4 antagonists 
such as Mozobil/Plerixafor[20]. In addition, administration of BL-8040 induces the 
mobilization of NK cells, T cells and B-cells from the BM and lymph nodes into the 
periphery. Using a syngeneic cancer model in mice it was demonstrated that BL-8040 
may eliminate the immunological barrier and allow the accumulation of immune cells 
within the tumor microenvironment (unpublished data). 
 
BL-8040 exhibited very high binding to human plasma proteins (99.2%) and high 
binding to the proteins in rat and dog plasma (94.9-96.9%) in the range of tested 
concentrations.  
 
The subcutaneous injection (SC) of BL-8040 was tested in GLP toxicology studies in 
dogs, and Rats with the main identified AE’s being a transient and local erythema at 
the injection site and peripheral edema. These reactions were noticed from a few 
minutes up to approximately 2 hours following the injection. There were no 
significant changes in terms of histopathology, Electrocardiogram (ECG), 
ophthalmological findings, blood chemistry or hematological variables. No target 
organ for toxicity could be identified.  
 
Clinical Studies 
 
BL-8040 has demonstrated safety and initial clinical efficacy in several Phase I and II 
studies: 
• A Phase IIa, non-randomized, open-label, single dose, dose escalation, safety 
study of BL-8040 in multiple myeloma subjects on top of G-CSF has been 
completed (NCT01010880, study BKTSC001).  
• A clinical trial for the treatment of adult relapsed/refractory Acute Myeloid 
Leukemia (AML) with a combination of BL-8040 and cytarabine (Ara-C) is 
currently ongoing (NCT01838395; BL-8040.01). 
• A 
Phase 
I, 
Two 
Part 
Study 
Exploring 
the 
Safety, 
Tolerability, 
Pharmacodynamic and Pharmacokinetic Effect of Ascending Doses of BL-8040 
in Healthy Subjects (NCT02073019, study BL-8040.02). 
• An Investigator Initiated Phase II study termed the “BLAST study” (Study No. 
UKH062014) is ongoing in Germany. This is a double-blind placebo controlled 
study that will assess the efficacy of BL-8040 as an add-on therapy to Ara-C for 

Protocol Version: 01/17/23, Amendment 2 
 
Page 19 of 33 
consolidation therapy in AML patients in first complete remission.  
 
In general, the most common AEs seen in all studies conducted with BL-8040 are 
injection site reactions, including: pain, erythema, pruritus and inflammation, and 
systemic reactions including among others: hives, pruritus (not at the injection site), 
flushing, chills, rash and urticaria. Other isolated AEs reported among others were 
paresthesia, musculoskeletal pain, headache, constipation, tingling, and elevation of 
liver function tests. 
 
For details concerning these studies please refer to the BL-8040 IB. 
 
9.2 
Nelarabine 
 
Mechanism of action: 
Nelarabine 
is 
a 
pro-drug 
of 
the 
deoxyguanosine 
analogue 
9-β-D-
arabinofuranosylguanine (ara-G), a nucleoside metabolic inhibitor. Nelarabine is 
demethylated by adenosine deaminase (ADA) to ara-G, mono-phosphorylated by 
deoxyguanosine kinase and deoxycytidine kinase, and subsequently converted to the 
active 5'-triphosphate, ara-GTP. Accumulation of ara-GTP in leukemic blasts allows 
for incorporation into deoxyribonucleic acid (DNA), leading to inhibition of DNA 
synthesis and cell death. Other mechanisms may contribute to the cytotoxic and 
systemic toxicity of nelarabine. 
 
Availability 
The commercially available supply of nelarabine will be used for this study.  
Nelararbine is supplied as a clear, colorless, sterile solution in glass vials. Each vial 
contains 250 mg of nelarabine (5 mg nelarabine per mL) and the inactive ingredient 
sodium chloride (4.5 mg per mL) in 50 mL Water for Injection, USP.  
 
Preparation, Storage, Stability and Administration 
Please refer to the FDA-approved package insert for product information, extensive 
preparation instructions, and a comprehensive list of adverse events.

CORRELATIVE STUDIES 
 
A bone marrow biopsy and aspirate will be obtained at baseline for correlative studies. 
Approximately 1 cm of the core biopsy should be placed in saline.  Approximately 5 mL of 
aspirate should be collected in a heparin containing tube.   
 
In addition, 30 ml of peripheral blood will be collected in a heparin containing tube on cycle 
1, day 1 immediately before and approximately 3 hours ± 1 hour after dosing of BL-8040.   
On day 2 of cycle 1, and additional 30 ml of peripheral blood will be collected in a heparin 
containing tube prior to the administration of BL-8040 or nelarabine. A separate 1 mL 
sample collected in an EDTA containing tube at the same time points will be used for a 
complete blood count. 
 
Samples should be maintained at room temperature and delivered or sent by overnight mail 
to the laboratory of Daniel C. Link located at Room 613 Southwest Tower of the Washington 
University Medical Center.

Preclinical studies predict that treatment with a CXCR4 antagonist will induce T-ALL 
apoptosis through mobilization from perivascular niches in the bone marrow and through 
decreased c-Myc expression. To test these predictions, bone marrow and peripheral blood 
will be obtained from patients at baseline.  Peripheral blood will also be obtained 3 ± 1 hour 
after the first dose of BL-8040 and approximately 24 hours after the first dose of BL-8040 
(prior to the second dose of BL-8040). The following assays will be performed on these 
samples.

11.0 
STATISTICAL CONSIDERATIONS 
 
11.1 
Study Design 
 
This is an open label pilot study consisting of up to 20 patients. Demographic and 
clinical characteristics will be summarized using mean ± SD or median, IQR and 
extreme values for continuous values. Frequencies, percentages and confidence 
intervals will be reported for counts and proportions. Adverse events will be graded 
using NCI CTCAE v4.03 and summarized by patient, grade, frequency and time of 
occurrence. Kaplan-Meier product limit estimators will be used to estimate median 
and time-specific disease-free and overall survival. Cox proportional hazards 
regression will be used to describe time to neutrophil and platelet engraftment with 
early death treated as a competing risk. Additional Cox models may be used for time 
to event modeling to explore the effect of covariate adjustment. Pharmacodynamic 
data will be analyzed using descriptive statistics as described above, and plots. 
Differences between baseline and BL-8040 treated marrow will analyzed for 
significance using paired T-tests or Wilcoxon signed rank tests, as appropriate. 
 
Futility: No inferential procedures are planned, so futility cannot be defined as loss of 
power or inability of reject null hypotheses. With respect to safety, futility will be 

Protocol Version: 01/17/23, Amendment 2 
 
Page 22 of 33 
addressed by the monitoring rule described below.  With respect to tolerability, 
futility will be defined as the loss of no more than 4 patients, or 20% (6%, 44%) of 
the planned sample size, due to delayed hematologic recovery as defined in section 7 
or death occurring within the first 30 days of treatment or.   
 
11.2 
Monitoring Rule for Excess Mortality 
 
The estimated 30-day mortality in a population of patients with relapsed or 
refractory ALL is approximately 10%.  Toxicity will be reviewed on a continuous 
basis.   
 
Thirty day mortality will be monitored using a continuous toxicity monitoring rule: 
 
Suspend the study for 
review of the # deaths on or 
before 30 days due to 
toxicity is greater than: 
In the following number 
of enrolled patients: 
1 
6 
2 
14 
3 
20 
 
The probability is low (.055) of inappropriate early suspension if the true rate is 5% 
and remains low (.27) if the true rate is 11%. The probability is high (.68) of correct 
early suspension if the true rate is 20%.

Notification of Serious Adverse Events to BioLineRx 
 
Initial notification of SAEs 
An initial SAE report form must be completed and sent by fax/email to the BioLineRx 
Medical Monitor within 24 hours of the Investigator’s knowledge of the event. Any 
fatal or life-threatening event should be reported immediately, by phone, fax or email.  
 
Medical Monitor 
Dr. Anna Emde 
Mobile +972 54 2802352 
Email: safety8040@biolinerx.com 
Fax: + 972-8-642-9137 
 
The initial SAE report will be followed within 24 hours by a completed SAE report 
including a sufficiently detailed narrative, as well as copies of hospital case reports, 
results of applicable diagnostic tests, laboratory results, biopsy results, autopsy 
reports and other documents when requested and applicable. 
 
Minimum criteria for a valid initial SAE case: 
For regulatory purposes, initial SAE reports should be submitted to BioLineRx 
immediately and should include: 
• Protocol identification 
• A suspected investigational medicinal product, 
• An identifiable subject (e.g. study subject code number), 
• An AE with the Investigator’s assessment of seriousness and relationship to 
any the study drugs, 
• An identifiable reporting source i.e. Investigator contact details. 
 
Follow-up of SAEs 
A Follow-up SAE Report Form must be completed by the site (marked as “Follow-up 
report”) and sent to the Medical Monitor within a reasonable timeframe (an SAE 
Follow-up report is required whether or not there is any additional information to 
the initial report). 
 
The contact information for Follow-up SAE reporting is the same as for initial SAE 
reports (see above Section). 
 
12.8 
Timeframe for Reporting Required Events 
 
Adverse events will be collected from first dose of study treatment through 30 days 
after the last study treatment.  
 
 

Protocol Version: 01/17/23, Amendment 2 
 
Page 28 of 33 
 
12.9 
Exceptions in the Reporting of AE and SAE 
 
According to EU and FDA detailed guidance on the collection, verification and 
presentation of adverse reaction reports arising from clinical trials on medicinal 
products for human use, regarding clinical trials in high morbidity or mortality 
diseases, it is acceptable to define some exceptions in the immediate reporting of 
specific SAEs. Refer to EU guidance ENTR/CT3, 5.1.9 and FDA guidance “Safety 
Reporting Requirements for INDs and BA/BE Studies” (Dec 2012). 
 
These AEs will be thoroughly handled and followed up through the CRF (AE form) 
and will be reviewed by the medical safety officer and could be re-qualified for 
reporting if necessary. 
 
Each event must be carefully analyzed by the Investigator’s or designee to decide 
whether the SAE could be considered as an exception or if it must be immediately 
reported. 
 
Exceptions for AE/SAE reporting are: 
All myelosuppression related adverse events: anemia, neutropenia, lymphopenia, 
leukopenia, leukocytosis. 
 
Grade 1-2 fatigue, weakness, nausea, alopecia, bone, joint or muscle pain, electrolyte 
abnormalities 
(sodium, 
potassium, 
carbon 
dioxide, 
calcium, 
magnesium, 
phosphorus) and glucose. 
 
 
13.0 
DATA AND SAFETY MONITORING 
 
In compliance with the Washington University Institutional Data and Safety Monitoring Plan, 
an independent Data and Safety Monitoring Committee (DSMC) will be specifically convened 
for this trial to review toxicity data at least once every 6 months following activation of the 
first secondary site.  A DSMC will consist of no fewer than 3 members including 2 clinical 
investigators and a biostatistician.  Like investigators, DSMC members are subject to the 
Washington University School of Medicine policies regarding standards of conduct. 
Individuals invited to serve on the DSMC will disclose any potential conflicts of interest to 
the trial principal investigator and/or appropriate university officials, in accordance with 
institution policies. Potential conflicts that develop during a trial or a member’s tenure on a 
DSMC must also be disclosed.  
 
The DSM report will be prepared by the study statistician with assistance from the study 
team, will be reviewed by the DSMC, and will be submitted to the Quality Assurance and 
Safety Monitoring Committee (QASMC).  This report will include: 
 
• HRPO protocol number, protocol title, Principal Investigator name, data coordinator 

Protocol Version: 01/17/23, Amendment 2 
 
Page 29 of 33 
name, regulatory coordinator name, and statistician 
• Date of initial HRPO approval, date of most recent consent HRPO approval/revision, 
date of HRPO expiration, date of most recent QA audit, study status, and phase of 
study 
• History of study including summary of substantive amendments; summary of accrual 
suspensions including start/stop dates and reason; and summary of protocol 
exceptions, error, or breach of confidentiality including start/stop dates and reason 
• Study-wide target accrual and study-wide actual accrual including numbers from 
participating sites 
• Protocol activation date at each participating site 
• Average rate of accrual observed in year 1, year 2, and subsequent years at each 
participating site 
• Expected accrual end date and accrual by site 
• Objectives of protocol with supporting data and list the number of participants who 
have met each objective 
• Measures of efficacy  
• Early stopping rules with supporting data and list the number of participants who 
have met the early stopping rules 
• Summary of toxicities at all participating sites 
• Abstract submissions/publications 
• Summary of any recent literature that may affect the safety or ethics of the study  
 
Further DSMC responsibilities are described in the DSMC charter. 
 
Until such a time as the first secondary site activates this protocol, a semi-annual DSM report 
to be prepared by the study team will be submitted to the QASM Committee beginning 6 
months after study activation at Washington University. 
 
The study principal investigator and coordinator will monitor for serious toxicities on an 
ongoing basis. Once the principal investigator or coordinator becomes aware of an adverse 
event, the AE will be reported to the HRPO and QASMC according to institutional guidelines 
(please refer to Section 12.0).

MULTICENTER REGULATORY REQUIREMENTS 
 
Washington University requires that each participating site sends its informed consent 
document to be reviewed and approved by the Washington University Regulatory 
Coordinator (or designee) prior to IRB/IEC submission.   
 
Site activation is defined as when the secondary site has received official written 
documentation from the coordinating center that the site has been approved to begin 
enrollment. At a minimum, each participating institution must have the following documents 
on file at Washington University prior to study activation. 
 
1. Documentation of IRB approval of the study in the form of a letter or other official 
document from the participating institution’s IRB. This documentation must show 
which version of the protocol was approved by the IRB. 
2. Documentation of IRB approval of an informed consent form. The consent must 
include a statement that data will be shared with Washington University, 
including the Quality Assurance and Safety Monitoring Committee (QASMC), the 
DSMC (if applicable), and the Washington University study team.
