Planned study period: 4Q 2016 (first patient in) to 
3Q 2018 (last patient in) 
2Q 2022 study completion 
Objectives: 
Primary: 
• To determine the efficacy of HBI-8000 administered twice a week (BIW) continuously
Secondary: 
• To evaluate the safety and tolerability of HBI-8000 administered BIW continuously
Endpoints: 
Primary: 
• Objective response rate (ORR; Complete Response [CR] + Partial Response [PR])
Secondary: 
• ORR by disease subtype (see inclusion criteria)
• Median duration of progression-free survival (PFS)
• Median duration of response (DOR)
• Safety
Exploratory: 
• Median duration of overall survival (OS)
• Pharmacokinetics (selected sites)
Study Design: 
This is a Phase 2b, open-label, non-randomized, single arm study to evaluate the safety, efficacy, 
and PK of HBI-8000 40 mg BIW in patients with relapsed or refractory PTCL (R/R PTCL).  
HBI-8000 will be administered orally approximately 30 minutes after any regular meal.  The 
treatment will be continuous, with 3-4 days between dosing.  A cycle is defined as 28 days solely 
for the purpose to schedule assessments required by the study.  
The study will continue till the last active Japanese subject initiates administration of the commercial 
product of HBI-8000 after the marketing authorization approval for relapsed or refractory PTCL in 
Japan. If there is no subject who is receiving study treatment at the time of the PTCL approval in 
Japan, the whole study will be completed at the time of the approval. 
In Japan, “Phase 2 study” shall be read as “post-marketing clinical study” and “investigator” shall 
be read as “post-marketing clinical study investigator” in this protocol after the marketing approval. 
In addition, other related terms are to be replaced in accordance with Article 56 of the Ministerial 
Ordinance on the Standards for the Implementation of Clinical Studies on Pharmaceutical Product 
(Japan GCP).  
Treatment-related adverse events (AEs) will be graded according to National Cancer Institute 
Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03.  In the event of 
unacceptable toxicities, study drug will be held until recovery and dosing will be resumed at 
reduced dose level, following protocol guidelines.  An unacceptable toxicity is defined as the 
following: 

 
 
 
Page 4 of 83 
 
 
 
• Grade 4 afebrile neutropenia > 7 days despite optimal growth factor support 
• Grade ≥ 3 febrile neutropenia or neutropenic infection 
• Grade ≥3 thrombocytopenia with clinically significant bleeding or Grade ≥3 
thrombocytopenia requiring a platelet transfusion 
• Grade ≥3 nausea, vomiting, diarrhea, or electrolyte imbalances lasting greater than 48 hours 
despite optimal prophylactic and curative treatment 
• Grade ≥3 allergic reaction 
• Grade ≥3 other non-hematologic AEs  
• Treatment delay >14 days secondary to recovery from study drugs- related AEs  
 
For determination of efficacy, HBI-8000 administration will be continued until disease progression 
(PD) or unacceptable toxicities are observed despite appropriate dose reduction or treatment 
interruption. Study drug treatment will be discontinued after the PTCL approval when the 
commercial product of HBI-8000 is available at the study sites. 
Number of patients: 
40 patients evaluable for efficacy with approximately 27 from Japan and 
13 from Korea.  To ensure meeting this target, an estimated 50 to 
60 patients would be enrolled in anticipation that some patients may not 
complete study treatment.

ventricular dysrhythmias (see Section 9.6)  
Prohibited from signing informed consent through the EoT 
assessment 
• 
Anti-cancer therapy other than study medication 
Prohibited during the study and within the following time intervals 
prior to the first dose of study drug. 
- 
4 weeks for anti-cancer chemotherapy 
-

- 
12 weeks for anti-cancer monoclonal antibody therapy 
Corticosteroid prescribed for medical conditions other than lymphoma is 
not considered as an anti-cancer therapy for this study, for example: 
chronic obstructive pulmonary disease, allergy, topical steroids for rash. 
Treatments: 
Study drug is to be taken after any regular meal twice weekly, each dose 
separated by 3-4 days.  Treatment will continue until PD in the absence 
of unacceptable toxicity, whichever is earlier. Study drug treatment will 
be completed when the commercial product of HBI-8000 is available at 
the study sites after the PTCL approval.  
Efficacy Data: 
 
Response and progression for PTCL will be evaluated according to the 
revised criteria for response assessment in lymphoma [Cheson 2014].  To 
be included in final efficacy analyses, the histopathology diagnosis of 
disease will be verified by Central Pathology Review, and disease 
response will be confirmed by Independent Radiology and Independent 
Overall Efficacy Review.   
Safety Data:  
All patients who receive at least one dose of HBI-8000 will be evaluable 
for safety.  Adverse event severity (grade) will be defined according to 
Common Terminology Criteria for Adverse Events (CTCAE) Version 
4.03.  Serial ECGs and clinical laboratory tests will be collected to 
evaluate safety and potential toxicity. Laboratory and other tests, as 
appropriate to the clinical situation, may be obtained more frequently than 
stipulated in the schedules of events.   
All reported AEs will be collected, evaluated and coded using Medical 
Dictionary for Regulatory Activities (MedDRA).

Pharmacokinetics 
data from selected 
sites: 
At sites participating in population PK assessments, blood samples for 
plasma HBI-8000 measurement will be taken on Day 1 of Cycle 1 at 
pre-dose, 1 h (± 15 min), 2 h (± 15 min), 3 h (± 15 min), 4 h (± 15 min), 5 
h (± 30 min), 7 h (± 30 min), 24 ± 1 h, 48 ± 1 h and 72 ± 1 h.  On Day 1 
of Cycle 2 (e.g., C2D1) PK samples will be taken at pre-dose and 1 h (± 
15 min), 2 h (± 15 min), 3 h (± 15 min), and 4 h (± 15 min).  On Day 1 of 
Cycles 3 to 6, only pre-dose PK samples will be taken.   
Statistical Procedures: 
Statistical analysis for all safety, efficacy, and PK parameters will be primarily descriptive in nature.  
Categorical variables will be summarized by frequency distributions (number and percentages of 
patients), continuous variables will be summarized by mean, standard deviation, median, minimum, 
maximum, and time-to-event variables will be summarized using Kaplan-Meier methods and 
figures for the estimated median time.  A formal statistical analysis plan will be completed prior to 
database lock and any study-related analyses.  
 
Disease diagnosis including histological subtypes will be confirmed by central pathology review 
conducted by independent pathologists.   
Efficacy should be analyzed using Full analysis set (FAS) and Per protocol set (PPS).  
The FAS is defined as Patients meeting all eligibility criteria and having received at least one dose 
of study medication, and at least one efficacy assessment of disease with either imaging studies or 
clinical examination after receiving study medication. 
 The PPS is defined as Patients meeting all eligibility criteria and having completed Cycle 1 
treatment or discontinued study treatment during cycle 1 due to clinical PD. It should be noted that 
the PPS includes subjects who discontinue within Cycle 1 due to clinical PD without imaging 
studies to assess disease status.  
 In addition, Patients who are assessed as Non-PTCL by the central pathology review committee 
should be excluded from the FAS and PPS for efficacy. The non-PTCL subjects will be included in 
safety analysis for the study. 
The primary efficacy analysis is conducted in the PPS. The Efficacy analysis using the FAS will be 
also reported. 
It is estimated that 40 evaluable patients are adequate to provide efficacy assessment. Assuming a 
30% ORR in this population of 40 evaluable patients, the conclusion would be that there is a 95% 
chance that the ORR in this protocol population would lie between 15.8% and 44.2%. The power 
for showing the response rate >10% at 5% two-sided alpha in 40 patients is 89%.  
 
All patients who have received any amount of study medication will be considered as evaluable for 
safety.  Safety data will be summarized with descriptive statistics and frequency tables and will 
include AEs, hematology, coagulation, serum chemistry, urinalysis, vital signs, and ECG data. 
Laboratory values will be summarized by numerical value and toxicity grade.

Montgomery, and Olson 2009]. 
The activity of Class I HDACs (HDAC isoenzymes 1, 2, 3, and 8) is elevated in acute 
myelogenous leukemia, acute promyelocytic leukemia, non-Hodgkin’s lymphoma (NHL), as 
well as prostate, gastric, colorectal, breast, and cervical cancers [Bolden, Peart, and Johnstone 
2006; Nakagawa et al. 2007; Fritzsche et al. 2008; Weichert et al. 2008a; Weichert et al. 2008b]. 
Small interfering RNA (siRNA)-mediated inhibition of HDAC 1 or 3 resulted in anti-
proliferative effects, and HDAC2 inhibition using siRNA sensitized tumor cells to apoptosis 
[Haberland, Montgomery, and Olson 2009]. 
Class IIb HDACs (HDAC isoenzymes 6 and 10) preferentially target non-histone proteins, 
such as α-tubulin and heat shock protein (HSP) 90.  Heat shock protein 90 has been shown to 
participate in malignant transformation by stabilizing oncoproteins such as Bcr-Abl, mutant 
Flt-3, AKT, c-Raf, estrogen receptors, Her-2, and vascular endothelial growth factor receptor.  
Alpha-tubulin suppresses apoptosis in tumor cells by facilitating lysosomal clearance of 
misfolded proteins.  Deacetylation of HSP90 and α-tubulin by HDAC6 or HDAC10 activates 
these proteins, contributing to the malignant phenotype.  Conversely, inhibition of HDAC6 or 
HDAC10 has been shown to inhibit tumor growth.  The synergy observed with the HSP90 
inhibitor 17-alpha 1-acid glycoprotein and the anti-tumor proteasome inhibitor bortezomib 
further support these proposed mechanisms [Glaser, et al. 2004, Bali et al. 2005, Rodriguez-
Gonzalez et al. 2008, Schemies, Sippl, and, Jung 2009, Park 2008]. 
Several HDAC inhibitors have been approved by the Food and Drug Administration (FDA) 
for the treatment of T-cell lymphoma (TCL), including vorinostat (ZOLINZA®, Merck & Co. 
Inc., October 2006) for the treatment of cutaneous manifestations in patients with cutaneous 
T-cell lymphoma (CTCL) who have progressive, persistent, or recurrent disease after two 
systemic therapies, romidepsin (ISTODAX®, Celgene Corporation, November 2009) for the 
treatment of CTCL and subsequently for PTCL, and belinostat (BELEODAC®, Spectrum 
Pharmaceuticals, Inc., July 2014) received accelerated approval from FDA for the treatment 
of patients with relapsed or refractory PTCL.  Panobinostat (FARYDAK®, Novartis 
Corporation, February 2015) was approved in combination with bortezomib and 
dexamethasone for the treatment of patients with multiple myeloma.  Several other HDACi are 
under clinical evaluation, including the following different classes: hydroxamic acid (e.g., 
resminostat, pracinostat, abexinostat, quisinostat), cyclic peptide (e.g., FK228/romidepsin), 
short-chain fatty acid (e.g., valproic acid), and benzamide (e.g., entinostat, mocetinostat, HBI-
8000). 
Preliminary results have suggested that HDACi are active in non-small cell lung cancer and 
breast carcinoma when combined with other anti-tumor agents, however, their activity as 
single agent in solid tumors has not been demonstrated in clinical trials [Blumenschein et al 
2008, Crump et al 2008, Modesitt et al 2008, Vansteenkiste et al 2008, Luu 2009]. 
 
Rationale for the Use of HBI-8000 for the Treatment of Cancer 
HBI-8000 inhibits several cancer-associated Class I (HDAC 1, 2, 3) and one Class IIb HDAC 
(isoenzymes 10) HDACs in the nanomolar range and stimulates accumulation of acetylated 

 
 
 
Page 17 of 83 
 
 
histones H3 and H4 in tumor cells [Ning et al 2012].  In vitro, HBI-8000 inhibits the growth 
of a wide variety of tumor cell lines, with 50% inhibitory concentrations (IC50s) in the single-
digit micromolar range.  HBI-8000 is non-toxic to non-transformed cells (IC50s ≥ 100 
micromolar) [Ning et al 2012].  In vivo, HBI-8000 has demonstrated dose-dependent anti-
tumor activity against human xenograft models [Ning et al 2012].  Results from pre-clinical 
pharmacokinetics (PK) and toxicology studies in rats and dogs as well as results from a Phase 1 
study conducted to date [Shenzhen Chipscreen Study Report 2008] suggest that HBI-8000 has 
favorable PK and safety profiles.  
Emerging data suggest that there are three major mechanisms underlying the anti-cancer 
activities of HDACi: preferential induction of growth arrest and apoptosis in blood and 
lymphoid-derived tumor cells, enhancement of both NK-mediated and CD8+ Cytotoxic T 
lymphocyte -mediated antigen-specific anti-tumor immunity, and partial reversal of epithelial 
mesenchymal transition and drug resistance of tumor cells as described in Fig. 2. However, the 
activation of natural killer (NK)- and antigen-specific Cytotoxic T lymphocyte -mediated 
cellular anti-tumor immunity appears only to be associated with the benzamide type of 
sel4ctive HDACi such as HBI-8000 (Figure 2).

Immunomodulatory Mechanisms Integrate with Cancer Cell Intrinsic 
Mechanisms of Cell Killing by HDACi  
It has been theorized that cancer is caused by genetic defects: gene mutations, abnormal gene 
expression and epigenetic dysregulation, which occur in cancer cells but these mechanisms are 
not limited to cancer cells and could affect immune cell function as well.  Some of these cancer 

 
 
 
Page 18 of 83 
 
 
cell intrinsic defects are reversible and the promise of epigenetic regulators like HDACi is that 
they can concurrently target multiple aberrant or compensatory signaling pathways found in 
cancer cells by restoring the genome, and by extension the transcriptome, to more normal-like 
state.  HBI-8000 causes modulation of gene regulation patterns that is consistent with that 
hypothesis.  Genes in several functional clusters were regulated by HBI-8000 [Ning et al 2012, 
Pan et al 2014], including several genes important for cell cycle (CCNA2/Cyclin A2, 
CCNB2/Cyclin B2, CCNE2/Cyclin E2, CDKN1A/p21/WAF1, CHEK1/checkpoint kinase 1), 
apoptosis (DR6/ TNFRSF21/death receptor 6) and the response to antitumor therapies 
(ABCB10, ABCC2/MRP2, RAD23B, UBCH10/ubiquitin-conjugating enzyme E2C).  HBI-
8000 also regulated genes promoting epithelial differentiation (CDH1, KRT8) and reducing 
the epithelial-to-mesenchyme transition, an important process in tumor invasion and metastasis 
(CDH2/N-cadherin).  While these HDACi effects on the cancer cell are important, the effects 
of HDACi are not limited to regulation of cell cycle, cell differentiation and cell death, but also 
affect immune recognition through effects on the cancer cell and immunocytes. 
Notably, HDAC inhibitors increase tumor cell ligands promoting NK cell-mediated tumor cell 
lysis, and NKG2D expression on NK cells involved in tumor cell lysis, thereby promoting 
tumor immunocyte interactions involved in immune surveillance.  For example, in a pancreatic 
cancer model, exposure to valproic acid, an inhibitor of HDAC classes 1 and 2 (but not 6 and 
10), upregulates NKG2D ligands and major histocompatibility complex class I-related chains 
A and B (MICA and MICB) in pancreatic cancer cells, thereby increasing susceptibility of 
tumor cells to NK cell-mediated cell lysis in vitro [Shi et al 2014].  HDAC inhibition by 
entinostat is also associated with enhanced NK cell cytotoxicity against colon carcinoma and 
NK cells associated with increase in MIC expression in tumor cells and NKG2D in primary 
human NK cells [Zhu et al 2015]. 
 
Nonclinical Studies 
HBI-8000 is metabolized, in part, by the cytochrome P450 (CYP) 3A4 pathway, and it inhibits 
CYP3A4 and CYP2C8.  The estimated IC50’s of HBI-8000 for CYP inhibition in pooled human 
liver microsomes were 12.7 μM (CYP2C8) and 1.47 μM (CYP3A4).  Other CYP isoenzymes 
were not significantly inhibited by HBI-8000.  Peak plasma concentrations for HBI-8000 in 
the planned clinical studies are expected to be well below the IC50 for inhibition of CYP3A4 
and CYP2C8, suggesting low potential for significant inhibition of the metabolism of CYP3A4 
or CYP2C8 substrates.  
The findings in toxicology studies conducted in the U.S. and China were consistent.  At dosing 
levels just above the ‘no observed adverse effect level’, the findings across several species 
were gastrointestinal disturbances, loss of appetite, diarrhea, and myeloid and lymphoid 
suppression.  At higher exposure, these effects increased, and oligospermia and mucosal 
hemorrhage in the gastrointestinal tract were also observed.  Sporadic signs of focal myocardial 
inflammation and necrosis were seen in some studies, as were occasional prolonged QT 
intervals in one dog study.  All of these cardiac changes were found only at high exposures, 
were reversible, were inconsistent across studies, and may have been related to the poor 
metabolic condition of animals receiving such high doses of HBI-8000.  Overall, the main 

 
 
 
Page 19 of 83 
 
 
target tissue toxicities of HBI-8000 in rats and dogs are in bone marrow, lymphoid tissue, and 
the gastrointestinal tract.   
Further information on non-clinical studies conducted with HBI-8000/chidamide may be found 
in the Investigator’s Brochure [IB 2020].  For the following discussion, the names HBI-8000 
and chidamide are used interchangeably, although chidamide will be used to describe data 
generated by Chipscreen. 
 
Clinical Pharmacology 
 
Absorption 
The single-dose PK of chidamide was evaluated in 33 patients with TCL. After a single oral 
administration of 30 mg of chidamide after any regular meal, the average time to peak plasma 
drug concentration was approximately 4 hours, average peak plasma drug concentration (Cmax) 
60 ng/ml, average area under curve (AUC0-t) 660 ng×h/mL and the average endpoint 
elimination half-life 17 hours.  
The multi-dose PK parameters of chidamide were evaluated in 19 TCL patients administered 
with multiple doses of chidamide. Compared to that of single dose patients, the AUC0-t value 
increased 1.8 folds after the 8th dose, and the differences were statistically significant (p<0.01). 
The correlation between drug exposure and the efficacy and/or safety of chidamide remains to 
be established. 
The effect of dose on PK was evaluated in 21 patients with advanced stage solid tumor or 
lymphoma.  A single dose of 25, 32.5 or 50 mg chidamide tablet was administered, the AUC0-
t were 809±390, 828±509 and 1120±438 ng×h/mL, respectively, indicating non-proportional 
increase of drug exposure versus the increasing dose, and possible dose saturation. 
The bioavailability of chidamide appeared to be higher when taken with food.  The effect of 
food on PK was studied in seven patients with TCL. When 30 mg chidamide was ingested 30 
minutes after any regular meal, the mean plasma drug exposure was 2.3-fold of that when the 
same dose was administered in fasting state.  
It was observed in the clinical trials that administration of drug after any regular meal could 
alleviate gastrointestinal irritation caused by the drug in some patients.  It is thus recommended 
to take the medication at least 30 minutes after any regular meal.  
In clinical studies conducted in China, it was noted that some clinical features were associated 
with drug exposure. The time to Cmax shortened and Cmax increased with increasing age; 
average drug exposure (unit AUClast) for male patients was about 80% of that for females at 
the same dosage.  However, its correlation with the efficacy and safety remained unknown.  
In a Phase 1 trial conducted in the U.S. (Study HBI-8000-101), HBI-8000 was administered 
three times a week (TIW) continuously, significant inter-patient variability was observed.  
There was suggestion of some drug accumulation between Day 1 and Day 19.  On Day 19, 
AUC ranged from 1.3 to 2.2-fold of Day 1 and Cmax ranged from 0.9 to 3.1-fold of Day 1.  Due 

 
 
 
Page 20 of 83 
 
 
to significant variability across doses among 2-3 patients in each dose group, no definitive 
conclusion could be made.  However, no gender difference was observed in this trial. 
In a Phase 1 trial conducted in Japan (Study HBI-8000-201), HBI-8000 was administered two 
times a week continuously. 
 
Distribution 
The apparent volume of distribution of chidamide is relatively large, indicating broad 
distribution in the human body. In vitro studies have shown that in human plasma 89.1 to 
99.3% of chidamide was protein-bound. 
 
Metabolism and Excretion 
Nuclear magnetic resonance and liquid chromatography-tandem mass spectrometry were used 
to investigate the biological conversion and material balance in 4 patients with TCL.  Seven 
days after a single dose of 30 mg, 80.2 ± 9.5% of chidamide was excreted in urine and feces, 
the majority of which occurred within the first 72 hours.  Chidamide was eliminated 
predominantly (67.6 ± 12.7%) through urine, and the remaining 12.6 ± 7.7% through feces.  In 
the excreted chidamide, the parent drug form was 37.6 ± 9.2% of total dosage, of which 39.4% 
was through urine and 86.9% was through feces.  There were also 5 main metabolites, products 
of mono-oxidation at different positions and hydrolysis of benzamide bond through two major 
metabolic pathways. 
Further information on clinical pharmacological studies with HBI-8000/chidamide may be 
found in the Investigator’s Brochure [IB 2020]. 
 
Clinical Studies 
To date, more than 800 patients have been dosed with HBI-8000/chidamide in clinical trials. 
Over 26,000 patients have been prescribed chidamide (Epidaza) in China since marketing 
approval was granted in December 2014. 
Clinical trials with HBI-8000 have shown that HBI-8000 is generally well tolerated in patients 
with advanced solid tumors or relapsed or refractory lymphoma at doses up to 32.5 mg TIW 
and 50 mg BIW administered continuously with or without intermittent breaks (total weekly 
doses of approximately 100 mg in Phase 1 trials).  The Phase 2 registration study in PTCL 
conducted in China demonstrated significant efficacy, with the best response rate of 28% 
(22/79) and a good safety profile. A subgroup analysis of the various histological subtypes 
revealed that the ORR was as high as 44 to 50% [Shi 2013, Shi 2015].  Based on these data, 
the CFDA granted conditional approval on December 23, 2014 for the use of chidamide (HBI-
8000) for the treatment of relapsed or refractory PTCL. 
In Japan, pharmaceutical and medical devices agency (PMDA) was consulted in 2013 to obtain 
advice for the clinical development of HBI-8000 for relapsed or refractory PTCL and ATLL 
in Japan. For a Phase 2 dose selection, a Phase 1 study (HBI-8000-201) in patients with 
relapsed or refractory Non-Hodgkins Lymphoma (NHL) including PTCL and ATLL was 

 
 
 
Page 21 of 83 
 
 
initiated in Japan in April, 2014 and has completed. In addition, Phase 2 study in relapsed or 
refractory ATLL was initiated in 2016 and has completed. HUYBIO received approval from 
MLHW for relapsed or refractory ATLL in June 2021. The Phase 2 study in PTCL is this 
protocol. 
 
Rationale for Investigation in Relapsed and Refractory Peripheral T-
Cell Lymphoma (PTCL) 
Peripheral T-Cell Lymphoma (PTCL) s a group of usually aggressive and relatively treatment-
resistant peripheral NHLs that develop from mature T cells (TCL).  Peripheral T-Cell 
Lymphomas  are sub-classified into various subtypes, each of which are typically considered 
to be separate diseases based on their distinct clinical, morphologic, immunophenotypic and 
genetic features [Jaffe 2009]. The 3 most common subtypes of PTCL, not otherwise specified 
(PTCL-NOS), anaplastic large-cell lymphoma (ALCL), and angioimmunoblastic T-cell 
lymphoma (AITL), account for approximately 70% of all PTCLs, although there are 
geographical (North America, Europe and Asia) differences in the prevalence of the different 
subtypes, with ATLL and NK/T-cell lymphoma  being more common in Asia [Vose, Armitage, 
Weisenburger 2008]. 
The frontline therapy for PTCL has been multi-agent chemotherapy. Once disease has relapsed 
or if disease fails to respond to frontline therapy, treatment options are limited.  In Japan, 
mogamulizumab, a humanized monoclonal antibody directed against chemokine (C-C motif) 
receptor 4 (CCR4), has been available for the treatment of relapsed or refractory CCR4+ ATLL 
since 2012 and has been approved by PMDA for PTCL and CTCL based on a Phase 2 clinical 
trial in 2014.  CCR4 is over-expressed on various malignant T cells, including ATLL, PTCL 
and CTCL cells. Approximately 50% of PTCL patients are CCR4+, hence eligible to receive 
mogamulizumab. 
Clinical trials of mogamulizumab have shown that not all patients would respond to treatment.  
In fact, the response rate from the Phase 2 trial in Japan was 34% with a median progression 
free survival (PFS) of 3 months [Ogura et al 2014].  In Phase 1/2 trials conducted in the U.S., 
the overall response rate (ORR) was 37%, while in the EU, the ORR was only 11% with PFS 
of 2.1 months [Zinzani et al 2014].  The low ORR (11 to 37%) suggests that about two thirds 
of mogamulizumab-treated CCR4+ PTCL patients would still require other treatments.  Also, 
clinically significant adverse drug reactions have been observed with mogamulizumab, in 
particular, Stevens-Johnson Syndrome. Thus, treatment with better efficacy and safety is still 
needed. The planned study HBI-8000-203 will be conducted to evaluate the efficacy and safety 
of HBI-8000 in relapsed and refractory PTCL to address an unmet medical need. 
 
Dose Selection and Risk Assessment 
A Phase 1 dose finding study of HBI-8000 was conducted in Japan in NHL patients.  Based 
on the clinical experience from China (Section 1.6) where the CFDA approved dose of 
chidamide (Epidaza) is 30 mg BIW, the starting dose of this study was 30 mg.  Data to date 
have shown that both 30 mg and 40 mg dose levels were well tolerated.  The Grade 3 and 4 

 
 
 
Page 22 of 83 
 
 
toxicities observed at 40 mg in 2 out of 6 patients were transient, and asymptomatic.  The grade 
4 neutropenia was asymptomatic resolved promptly with administration of granulocyte colony 
stimulating factor.  The Grade 3 alanine aminotransferase (ALT) elevation was also 
asymptomatic resolved with dosing interruption.  On the other hand, strong signals of efficacy 
were observed at 40 mg as evidenced by none of the seven patients showing disease 
progression (PD)and five achieving partial response.  Upon review of risk and benefit in 
totality, the 40 mg BIW schedule was selected as the starting dose for the Phase 2. 
In clinical studies, treatment with HBI-8000 has been associated with myelosuppression, 
including thrombocytopenia, neutropenia and/or leukopenia and anemia or decreased 
hemoglobin.  Other adverse drug reactions reported in previous clinical trials include nausea, 
diarrhea, fatigue/lethargy, abdominal pain, vomiting, peripheral edema, pyrexia/fever, 
anorexia, dizziness, decreased appetite and transaminase increase.  Recommendations for the 
management of dose modifications are presented in Sections 2.6.8 and 2.6.9.

2.0 STUDY OBJECTIVE(S)  
 
Primary Objective  
• To determine the efficacy of HBI-8000 administered BIW continuously 
 
Secondary Objective 
• 
To evaluate the safety and tolerability of HBI-8000 administered BIW continuously  
 
Criteria for Evaluation 
Efficacy Endpoints: 
Disease response will be assessed based on evaluation at baseline and postdose evaluations of 
nodal and extranodal lesions by imaging studies every 8 weeks.  Evaluation of nodal lesions 
and extranodal lesions will be performed according to the revised criteria for response 
assessment in lymphoma [Cheson 2014] (see Section 9.4). 
Primary: 
• Objective response rate [ORR; Complete Response (CR) + Partial Response(PR)]  
Secondary: 
• ORR by disease subtype (see Section 2.5.1) 
• Median duration of PFS  
• Median duration of response (DOR)  
Exploratory: 
• Median duration of overall survival (OS) 
• Pharmacokinetics (for selected sites) 
Safety Endpoints: 
Safety and tolerability of HBI-8000 will be measured by the number of patients with adverse 
events (AEs) and severity of AEs as defined by Common Terminology Criteria for Adverse 
Events (CTCAE) v.4.03.  Adverse events reported by the patients or observed during physical 
examination, vital signs assessments, ECGs, and laboratory tests results will be recorded and 
assessed by severity and association with study treatment.  
Population Pharmacokinetic Characterization Study (applicable to participating sites and 
consented patients): 
Population PK will be conducted at selected sites in Japan.  At these sites, only patients that 
consent to this PK study will participate.  To obtain comparable PK database from Japan and 
Korea and to assess regional difference, if any, PK characterization will be required for all 
patients enrolled in Korea.  PK sampling will be performed as detailed in Table 5 of 
Appendix A.

Summary of Study Design 
This is a Phase 2b, open-label, non-randomized, single arm study to evaluate the efficacy, 
safety, and PK of HBI-8000 in patients with relapsed or refractory PTCL.  Study patients will 
ingest HBI-8000 approximately 30 minutes after any regular meal BIW.  There will be 3 to 4 
days between dosing.  A treatment cycle is defined as 28 consecutive days.  HBI-8000 
administration will be continued until PD or the occurrence of unacceptable toxicities despite 
optimal supportive care.  
The study will continue till the last active Japanese subject initiates administration of the 
commercial product of HBI-8000 after the marketing authorization approval for relapsed or 
refractory PTCL in Japan. If there is no subject who is receiving study treatment at the time of 
the PTCL approval in Japan, the whole study will be completed at the time of the approval. 
In Japan, “Phase 2 study” shall be read as “post-marketing clinical study” and “investigator” 
shall be read as “post-marketing clinical study investigator” in this protocol after the marketing 
approval. In addition, other related terms are to be replaced in accordance with Article 56 of 
the Ministerial Ordinance on the Standards for the Implementation of Clinical Studies on 
Pharmaceutical Product (Japan GCP).  
Response and progression for PTCL will be evaluated according to the revised criteria for 
response assessment in lymphoma. [Cheson et al 2014] (see Section 9.4). 
 
Safety Determination and Criteria for Dose Modification or Interruption 
National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) 
version 4.03 will be used to grade the severity of toxicities.  Abnormalities of laboratory tests 
(investigation) must be evaluated for clinical significance.  Study treatment may be held, and 
dose may be reduced in the event of unacceptable toxicities. (see Section 2.6.8 for Guidelines.)

Study Procedures Overview 
Patients may be treated in this study as long as they receive clinical benefit (stable disease or 
a response) in the absence of unacceptable toxicity.  Disease progression would be determined 
by investigators based on local radiology findings and clinical judgement.  No independent 
radiology review is required prior to designation of PD and treatment discontinuation.  
Independent Radiology Review and Independent Overall Efficacy Review will be performed 
for final efficacy analyses at the completion of this study.

To ensure patient safety, a data safety monitoring board (DSMB) will convene to review the 
cumulative safety profiles of study patients at following milestones: first 6 patients completing 
at least 1 cycle, 12, 18, 30 patients have been treated for at least 1 cycle and at end of treatment 
Phase of the study.  Based on the observed safety, dose and regimen of ongoing treatment may 
be modified as needed.  For all patients, weekly safety laboratory tests will be obtained during 
the first 28 days and closely monitored for safety signals, especially for neutropenia and 
transaminase elevation. 
It is estimated that each patient will be on study for up to 42 months after enrollment.  
Assuming that 24 months are needed to meet accrual target, the study period would be of 
66 months to allow efficacy and safety determination. After study drug is discontinued, 
patients will be followed as described in Sections 2.6.4 and 2.6.5.  
Patients will be screened by the study site investigator prior to entry into the study.  Patients 
will receive a detailed explanation of the study design, and the potential risk/benefit of 
treatment will be disclosed to patients prior to the screening process.  Only eligible and 
consenting patients will be enrolled into the study.  Local histopathology report could be used 
to consent patient.  Central pathology review will be completed before efficacy analysis.  The 
investigator will maintain a pre-screening log to record all patients prior to screening.  
Similarly, local radiology reports on disease status will guide investigator’s decision on study 
treatment, including discontinuation.  At end of the study, tumor response of each patient will 
be reviewed by independent radiologists and oncologists in a blinded fashion to obtain best 
response, dates of response and progression.  The data from independent and local assessment 
will be analyzed in parallel in final study report. 
The Schedule of Events is presented in Table 4 of Appendix A (Section 9.1).  The timing of 
PK sampling is provided in Table 5 of Appendix A. 
 
Screening Assessments (within 28 days prior to start of treatment)  
Written informed consent for participation in the study must be obtained before performing 
any study-specific screening tests or evaluations.  Informed Consent Forms (ICFs) for all 
patients screened (whether enrolled or not) will be maintained at the study site. 
All screening and baseline assessments must be completed and reviewed to confirm that 
patients meet all eligibility criteria.  An Eligibility Screening Form (ESF) documenting the 
investigator’s assessment of each screened patient with regard to the protocol’s inclusion and 
exclusion criteria is to be completed and kept at the study site. 
Screening assessments include medical history and concomitant medications, documentation 
of PTCL diagnosis in accordance with the WHO revised classification (WHO 2008) and 
treatment history.  To consent a patient to allow screening procedure, local histology diagnosis 
for PTCL is acceptable.  Unstained tumor pathology slides will be sent to pathology central 
laboratory and stained at the central laboratory.  The images will be captured from the slides 
for central pathology review that is to be completed  before efficacy analysis.  For patients who 
do not have enough tumor tissue archived, a new biopsy will be requested.  However, 
insufficient tumor tissue in archive or inability to perform new biopsy for any reason does not 

 
 
 
Page 28 of 83 
 
 
exclude patients from entering this study.  Reasonable efforts should be made to support central 
pathology review.  
Screening assessments will be performed within 28 days prior to Cycle 1 Day 1 (C1D1).  A 
pretreatment bone marrow test (aspiration or biopsy) would be required.  Results of standard-
of-care tests or examinations performed prior to obtaining informed consent and within 28 
days prior to C1D1 may be used (and do not need to be repeated for screening unless they do 
not meet the criteria defined in the protocol).  Similarly, tumor assessment tests <2 weeks 
outside the 28-day window in the absence of clinical evidence of PD, the results may be 
accepted. 
Women of childbearing potential must agree to practice effective contraceptive measures after 
signing informed consent.  A negative serum pregnancy test will be obtained during screening.  
 
Baseline Assessments on Cycle 1 Day1 (C1D1)  
Baseline assessments include a complete physical examination, vital signs, ECOG 
performance status, weight, concomitant medications, laboratory tests (hematology, chemistry, 
coagulation and urinalysis), and safety ECG. Women of childbearing potential must have a 
negative pregnancy status confirmed by serum test before dosing.  If Serum pregnancy test 
result cannot be obtained on the same day before dosing, urine pregnancy test should be 
conducted additionally and the result should be confirmed before dosing (see Section 9.1).  
Some of the pre-dose assessments except vital signs and ECG may be performed 1 day before 
C1D1 to accommodate scheduling requirements in the hospital. 
 
Treatment Phase 
All assessments must be performed as per the Schedule of Events (see Section 9.1. 
Assessments scheduled on the day of study treatment should be performed prior to taking study 
drug, unless otherwise noted in the schedule of assessments.  
Assessment of tumor response will be scheduled by end of the eighth week, then every 8 weeks 
(± 1 week) from C1D1.  However, if a patient develops clinical signs and symptoms of PD, or 
unacceptable toxicity occurs, tumor assessment may be performed sooner as needed.  For the 
patients with skin lesions, decision on treatment discontinuation should be based on computed 
tomography (CT) or positron emission tomography (PET-CT) assessment, not Modified 
Severity Weighted Assessment Tool (mSWAT) scores.  In other words, if imaging studies 
showing SD or PR while mSWAT score increases, treatment will continue. 
 
End of Treatment Safety Follow-up Visit 
All patients receiving at least one dose of HBI-8000 and discontinuing treatment for any reason 
except death will be assessed 30 (± 3) days after the last dosing of study drug, before the 
initiation of new cancer treatment or before the initiation of administration of commercial 
product of HBI-8000, whichever is earlier. Any patient for whom study treatment has been 
discontinued should complete study procedures listed in the EoT visit. At EoT safety visit, 
evaluations will include physical examination, vital signs, body weight, ECOG performance 

 
 
 
Page 29 of 83 
 
 
status, hematology, blood chemistry, urinalysis, pregnancy test (if applicable), ECG, and 
assessment of any ongoing adverse events.  If a patient discontinues study treatment before PD 
is recorded, and if the last tumor assessment was >30 days earlier from the EoT visit, tumor 
assessment should be performed at EoT. In these patients, further tumor assessments are to be 
performed approximately every 3 months ± 2 weeks until PD or the start of new cancer therapy 
whichever occurs first, unless consent to study participation is withdrawn or by completion of 
the whole study. If subjects cannot visit at site for this examination due to COVID-19 situation, 
investigators can skip the examination, and the assessment is to be performed approximately 
every 6 months ± 2 weeks. In this case, the investigator should document that fact in the 
medical record.    
Patients with HBI-8000-related AEs of Grade ≥2 observed at the EoT visit should be followed-
up and assessed monthly (phone calls/clinic visits) until the AEs have resolved to Grade ≤1 or 
are determined to be chronic, or patient receives other anti-cancer therapy. 
 
Survival Follow-up 
Follow-up for survival (and tumor status in patients in whom PD has not yet been observed) 
should occur at approximately 3-month intervals after the EoT visit.  Survival status may be 
conducted every 3 months ± 2 weeks by telephone contact or e-mail until death or end of study, 
defined as timing that the last Japanese subject initiates administration of the commercial 
product of HBI-8000. If there is no subject who is receiving study treatment at the time of the 
PTCL approval in Japan, the whole study will be completed at the time of the approval. The 
first subsequent anticancer therapy during this survival follow up period should be recorded 
with regimen and start date in the appropriate Electronic Case Report Form (eCRF).  
 
Patient Withdrawal 
Patients have the right to withdraw from the study at any time for any reason, and the 
investigator should try to ascertain the reason for withdrawal as completely as possible.  The 
investigator also has the authority to determine whether a patient should be discontinued from 
the study.  Study treatment may be discontinued and the patient withdrawn from the study 
under the following circumstances: 
• 
Unacceptable toxicity (AE)  
• 
Progression of the disease under study, except for isolated progression in skin lesion 
• 
Decision by the investigator to permanently discontinue study drug administration  
• 
Intercurrent illness that would, in the judgment of the investigator, affect clinical 
assessments, patient safety, or follow-up significantly 
• 
Significant protocol deviations that jeopardize the usefulness of the data 
• 
Repeated patient noncompliance 
• 
Patient is beginning another anti-cancer treatment protocol  
• 
Patient becomes pregnant  
• 
Patient requests to withdraw informed consent 
• 
Study termination by the sponsor 

 
 
 
Page 30 of 83 
 
 
All patients who withdraw from study treatment must complete an EoT visit, to be performed 
30 ± 3 days after the last dosing of the study drug (see Section 9.1), before the initiation of new 
cancer treatment or before the initiation of administration of commercial product of HBI-8000, 
whichever is earlier.  A patient may withdraw consent for treatment but still allow follow-up, 
in which case he/she should be followed for safety, survival, and disease status.  If a patient 
has withdrawn consent to study participation entirely, no subsequent follow-up will be 
performed. 
Patients who are lost to follow up or withdraw consent for study participation prior to receiving 
HBI-8000 or who withdraw before completing Cycle 1 for reasons unrelated to drug AEs or 
PD will be replaced.  
 
Discontinuation of the Study 
The whole study will be discontinued in any of the following cases: 
• 
Sponsor decides to discontinue development of the compound or the study 
• 
In the event of sponsor or regulatory authorities obtain safety information which 
does not allow continuation of the study 
 
Management and Dosage Modifications for Unacceptable Hematologic and 
Non-Hematologic Adverse Events 
National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) 
version 4.03 will be used to grade the severity of toxicities.  An unacceptable toxicity is defined 
as the following treatment-related AEs: 
• Grade 4 afebrile neutropenia >7 days despite optimal growth factor support 
• Grade ≥3 febrile neutropenia or neutropenic infection 
• Grade ≥3 thrombocytopenia with clinically significant bleeding or Grade ≥3 
thrombocytopenia requiring a platelet transfusion 
• Grade ≥3 nausea, vomiting, diarrhea, or electrolyte imbalances lasting greater than 
48 hours despite optimal prophylactic and curative treatment 
• Grade ≥3 allergic reaction 
• Grade ≥3 other non-hematologic AEs  
• Treatment delay >14 days secondary to recovery from study drugs- related AEs  
Table 1 summarizes the guidelines for dosage adjustment in the event of unacceptable AEs.  
Two dose reductions are allowed (from 40 mg to 30mg, or from 30 mg to 20 mg).  If 
unacceptable AEs recur despite 2 dose reductions, the study treatment will be permanently 
discontinued and post-treatment follow-up ensues. However, if the patients are having clinical 
benefit, further treatment may be considered after discussion with the sponsor.  In the event of 
AE, such as hematological AE-uncomplicated, necessitating two treatment interruptions, dose 
will be reduced when treatment resumes.  However, if strongly needed for patient safety, dose 
can be reduced according to the investigator judgement, even if unacceptable hematological 
AE-uncomplicated is occurred once.

AE: Adverse Event; G-CSF: granulocyte colony stimulating factor 
G-CSF is recommended to be prescribed when uncomplicated grade 3 or 4 neutropenia is 
observed.  Patient management should follow institution guidelines and be recorded in eCRFs.  
Laboratory tests should be obtained at least once a week to monitor recovery. 
 
Management and Dosage Modifications for Non-Hematologic Adverse 
Events  
In the event of Grade 3 non-hematologic AEs (excluding isolated abnormality of laboratory 
values not associated with clinical significance), study medication should be held.  Appropriate 
treatment should be initiated.  Patients will be closely monitored for recovery and managed 
following the Dose Adjustment Guideline.  If the AEs recur despite two dose reductions as 
applicable, study treatment should be discontinued.  Study treatment should be terminated if 
Grade 4 non-hematologic adverse events occur, following the Dose Adjustment Guideline.

Study Drug Administration 
During this trial, patients will receive 40 mg HBI-8000 administered approximately 30 minutes 
after any regular meal as four 10 mg tablets BIW continuously.  The dosing interval would be 
3 to 4 days for a total of 80 mg over 7 days. At each visit when study medication is dispensed, 
the study site staff will contact the Interactive Web Response System (IWRS) before 
dispensing. 
 
Packaging, Labelling and Storage 
HBI-8000 10 mg tablets are packaged in high density polyethylene bottles closed with an 
induction seal and a child-resistant cap and contain a desiccant pack, and a cotton coil.  Each 
bottle contains 26 tablets.  Study drug labels will contain information to meet the applicable 
regulatory requirements.  In case of discontinuation of treatment for any reason unused portion 
of the drug should be returned to hospital pharmacy. 
Drug product will be stored at 2 to 8 ° C at hospital pharmacy until dispensing.  After 
dispensing to patients, the drug will be transported to home in a cooler to maintain refrigerated 
condition.  Once at home, the drug will be kept refrigerated until administration and out of 
reach of children all the time. The study drug shall be read as post-marketing clinical study 
drug in this protocol after the PTCL approval. 
 
Patient Registration and Subject Number Assignment  
Based on medical history, potentially eligible patients will be identified.  After obtaining 
informed consent, the screening procedures will be performed and a 5-digit subject number 
will be assigned.  The first 3 digits are the site number (provided by the sponsor to study sites).  
The last 2 digits are a sequential number within a study site.  If a patient is assigned a subject 
number and later found unable to begin HBI-8000 administration, the patient will be replaced.  
A new subject number will be assigned to the replacement patient. 
 Concomitant Treatments 
All concomitant medications, regardless of whether they are prohibited or not, received after 
signing informed consent must be recorded on the eCRF.  Complete information on all 
concurrent medications (generic name of drugs, reason for use, dosage and duration of 
dosing, etc.) should be documented in the original records and in the eCRF. 
Patients should consult their investigator prior to using medications other than the study drug, 
including over-the-counter medications and supplements. 
 
Prohibited Medications and Therapy 
The following drugs are prohibited.  

 
 
 
Page 33 of 83 
 
 
• Drugs known to produce significant QT prolongation and ventricular dysrhythmias (see 
Section 9.6)  
Prohibited from signing informed consent through the EoT assessment 
• Anti-cancer therapy other than study medication 
Prohibited during the study and within the following time intervals prior to the first dose 
of study drug. 
− 4 weeks for anti-cancer chemotherapy 
− 6 weeks for nitrosourea and mitomycin C 
− 12 weeks for anti-cancer monoclonal antibody therapy 
Corticosteroid prescribed for medical conditions other than lymphoma is not considered 
as an anti-cancer therapy for this study, for example: chronic obstructive pulmonary 
disease for allergy, topical steroids for rash. 
Please note that patient use of any prohibited medication is considered a protocol violation.  In 
the event of prohibited medication use, investigator should consult study medical monitor to 
define an appropriate course of action if needed. 
 
Cautioned Medications 
Because the anti-emetic drug Zofran (ondansetron) is well known to prolong QTc, it is 
prohibited on 2 occasions, Cycle 1 Day 1 and Cycle 2 Day 1 when QTc test is scheduled.  
Starting 24 hours before the QTc test until the QTc test is completed on the next day, patient 
must not take Zofran over a 2-day period.  Although anti-emetics are rarely needed for 
HBI-8000, if anti-emetics must be used for other medical reason, alternative drug(s) should be 
used.  If a 5-HT3 antagonist must be used to manage severe emesis refractory to other 
medications, dosing should be postponed until resolution of underlying medical condition.  
In case it is medically necessary to co-administer drugs that could interfere with CYP3A4 
activity, investigators should monitor for toxicities and follow the study drug dose 
modifications for toxicity per study protocol.  Also, St. John’s wort should be used with caution. 
 
Permitted Medications 
Use of supportive care for AEs is permitted.  These treatments may include anti-emetics, 
antipyretics, antidiarrheal, anti-allergy agents, rash reliever, antihypertensive drugs, analgesics, 
antibiotics, hematopoietic growth factors and transfusion with blood products.  
Sulfamethoxazole Trimethoprim use is permitted.  However, when its side effects are observed, 
alternative antibiotics prophylaxis should be considered. 

 
 
 
Page 34 of 83 
 
 
 Dietary Restrictions 
Due to potential food-drug interactions for many commonly used medications, grapefruit, 
grapefruit juice, Seville oranges, and any products that contain Seville oranges or grapefruit 
should be avoided when possible. 
 Treatment Compliance 
The prescribed dosage, intervals between doses, and mode of administration, e.g., after meals, 
intact tablet (not crushed) may not be changed without direction by the investigators.  They 
must be recorded in the eCRFs.   
The patient will be provided with a drug log to record date and time of administration, time of 
meal prior to administration, AEs, and missed doses.  To verify compliance, the patient will be 
instructed to bring the drug log and study drug bottles (including any empties) to appointments 
scheduled for Day1 of each cycle starting with Cycle 2 for reconciliation.  
At each visit when study medication is dispensed previously dispensed study drug count will 
be confirmed by the investigator, or authorized designee, and compliance assessed prior to 
dispensing new study medication.  
Patients exhibiting poor compliance as assessed by tablet counts and not following dosing 
schedules should be counseled on the importance of good compliance to the study dosing 
regimen.  Noncompliance to drug amount is defined as taking <75% or >125% of study 
medication during a cycle.  Noncompliance to dosing interval is defined as more than 
2 occurrences of <3 days between doses during a cycle, for example, 1 or 2 days between doses 
#3 and #4 instead of 3 or 4 days according to a BIW schedule.  If in the opinion of investigator 
a patient is unable to follow instruction, study treatment should be discontinued. 
 Study Medication Accountability 
A clinical supplies shipment/receipt verification form will be enclosed with each study drug 
shipment.  The site pharmacist who receives the shipment should complete this form and 
clinical research associate should collect a copy of the form at each pharmacy visit.  If instead 
of the shipment/receipt verification form, a packing list is enclosed with the shipment, 
acknowledgment of the study drug receipt should be done through the IWRS system by the 
site pharmacist or authorized designee. 
The investigator, or authorized designee, must maintain a complete and accurate record of the 
receipt and distribution of all study medication using the Drug Accountability Form.  These 
forms will be described in detail in the pharmacy manual and must be available for inspection 
at any time. 
All study medication supplies should be accounted for at the termination of the study, and a 
written explanation provided for any discrepancies.  All unused study medication supplies and 

 
 
 
Page 35 of 83 
 
 
packaging materials are to be inventoried and returned to the local depot by the investigator, 
or authorized designee.  The investigator, or authorized designee, is not permitted to return or 
destroy unused clinical drug supplies or packaging materials unless authorized by the sponsor 
or delegate(s).

3.0 STUDY ASSESSMENTS 
 
Efficacy 
 
Primary Efficacy Endpoint 
The primary efficacy endpoint is to establish the ORR, defined as the proportion of patients 
with tumor size reduction of a predefined amount and for a minimum time period, evaluated 
by using the revised criteria for response assessment in lymphoma [Cheson 2014] (see 
Section 9.4). 
Tumor assessments will be performed by imaging modalities. CT, magnetic resonance imaging, 
or PET scanning may be used to evaluate lesions in the neck, chest, abdomen, and pelvis; and 
as a baseline evaluation for patients who may have brain metastases.  The PET-CT is 
encouraged to be performed from baseline.  However, when CT is the routine method to 
monitor patients according to hospital standard of care, PET-CT is not required.  Evaluation of 
nodal lesion and extranodal lesion will be performed according to the revised criteria for 
response assessment in lymphoma [Cheson 2014] (see Section 9.4).  Skin lesions are non-target 
lesions.  Their response will be assessed according to mSWAT, and contribute to overall 
response determination. 
Tumor response based on imaging studies will be confirmed with central review by independent 
radiologists at end of study prior to final efficacy analysis.  The dates of PR, CR and PD will 
be assessed as applicable.  Initial review will be performed by one independent radiologist.  If 
the results differ from those reported by the investigators based on local radiology findings, a 
second independent radiologist will be asked to adjudicate by way of assigning the final disease 
response to the determination made by either the investigators or independent radiologist. The 
overall efficacy review will be done by independent oncologist for final efficacy analysis. 
 
Secondary Efficacy Endpoints 
The secondary efficacy measures are: 
• ORR by disease subtype 
• Median duration of PFS defined as the time from the first dose of study medication to 
objective tumor progression or death. 
• Median DOR defined as the time from the first observation of tumor response to PD. 
 
Exploratory Endpoints 
• Median duration of overall survival  
• Pharmacokinetics

Safety 
 
Definitions 
 
Adverse Events 
An AE is any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of a medical treatment or procedure 
that may or may not be considered related to the medical treatment or procedure.  Assessment 
of the occurrence of an AE will be based on changes in the patient’s physical examination, 
laboratory results, and/or signs and symptoms.  An AE also includes any newly occurring event 
or previous condition that has increased in severity or frequency from signing the informed 
consent.  
Adverse events will be monitored until they are resolved or clearly determined to be due to a 
patient’s stable or chronic condition or intercurrent illness(es).  Medical care will be provided, 
as defined in the informed consent, for any AE related to study participation. 
 
Serious Adverse Event  
A serious adverse event (SAE) is any untoward medical occurrence resulting in the following: 
• Death 
• Is life-threatening (defined as an event in which the patient was at risk of death at the 
time of the event; it does not refer to an event which hypothetically might have caused 
death if it were more severe) 
• Requires in-patient hospitalization or causes prolongation of existing hospitalization 
• Results in persistent or significant disability/incapacity 
• Is a congenital anomaly/birth defect 
• Is an important medical event (defined as a medical event(s) that may not be 
immediately life-threatening or result in death or hospitalization, but, based upon 
appropriate medical and scientific judgment, may jeopardize the patient or may require 
intervention [e.g., medical or surgical] to prevent one of the other serious outcomes 
listed in the definition above).  Examples of such events include, but are not limited to, 
intensive treatment in an emergency room or at home for allergic bronchospasm; blood 
dyscrasias or convulsions that do not result in hospitalization. 
Although overdose is not always serious by regulatory definition, this event should be reported 
on an SAE form and sent to the sponsor in an expedited manner. 
All pregnancies, regardless of outcome, must be reported to the sponsor on a pregnancy form, 
not an SAE form. 

 
 
 
Page 38 of 83 
 
 
NOTE: 
The following hospitalizations are not considered SAEs in sponsor clinical studies: 
• A visit to the emergency room or other hospital department lasting <24 hours, that does 
not result in admission (unless considered “important medical event” or event that is 
“life-threatening”) 
• Elective surgery planned prior to signing consent 
• Admissions as per protocol for a planned medical/surgical procedure 
• Routine health assessment requiring admission for pretreatment assessment/trending of 
health status (e.g., routine colonoscopy) 
• Medical/surgical admission for purpose other than remedying ill health state and was 
planned prior to signing consent.  Appropriate documentation is required in these cases 
• Admission encountered for another life circumstance that carries no bearing on health 
status and requires no medical/surgical intervention (e.g., lack of housing, economic 
inadequacy, care-giver respite, family circumstances, administrative) 
• Admission for Progressive Disease (PD) 
 
Period of Observation 
All AEs (including SAEs) regardless of the relationship to study drug or study procedure will 
be collected from obtaining informed consent to the EoT assessment. At EoT, AEs Grade ≥2 
considered to be at least possibly related to the study drug must be followed up after the EoT 
assessment until the events have recovered to Grade ≤1, returned to the baseline level, are 
judged by the investigator to be stabilized, or to be given a reason that further follow up will 
not be required (see Section 2.6.4).  However, if the patient begins to receive new cancer 
therapy or withdraws consent to study participation, no further follow-up will be conducted.  
The outcome of the events which do not resolved by that time will be recorded as “ongoing” 
on the eCRF. 
 
Preexisting Conditions 
A preexisting condition will not be reported as an AE unless the condition worsens by at least 
one CTCAE grade during the study.  However, the pre-existing condition must be recorded in 
the screening eCRF as a pre-existing condition, and all concomitant medication administered 
for the condition must be recorded as concomitant medication in the eCRF following 
guidelines for other concomitant medication. 
 
Documentation and Reporting of Adverse Events by Investigator 
Any signs and symptoms that occur after obtaining the informed consent will be described as 
AEs and graded according to the CTCAE in the AE section of the eCRF.   

 
 
 
Page 39 of 83 
 
 
Abnormal laboratory values will be recorded on the laboratory section of the eCRF and not in 
the AE section.  Abnormal laboratory results leading to a clinical diagnosis will be reported 
with a clinical term by the investigator and recorded in the AE section of the eCRF in addition 
to the laboratory section.  Abnormal laboratory results that meet the definition of an SAE 
should also be reported on an SAE form.  Relationship (reasonable causal relationship) to drug 
treatment and countermeasures taken will be noted on the eCRF.  Investigators must record in 
the eCRF their opinion concerning the relationship of the AE to study therapy. 
Disease progression should not be recorded as an AE.  Diagnostic and therapeutic non-invasive 
and invasive procedures, such as surgery, will not be reported as an AE, but the procedure 
and/or therapeutic treatment should be recorded on the appropriate eCRF.  The medical 
condition for which the procedure was performed must be reported. 
 
Assessment of Causal Relationship to Study Drug 
The relationship of an AE to the study medication is graded as follows: 
Definite: 
• Distinct temporal relationship with the study drug  
• Stops/improves when the study drug has been stopped 
• Can reasonably be explained by known characteristics of the drug 
Probable: 
• Reasonable temporal sequence from the study drug administration 
• Stops/improves when the study drug has been stopped 
• Event cannot easily be explained by patient’s clinical state or other factors 
Possible: 
• Reasonable temporal relationship with the study drug 
• Event could have been produced by the patient’s clinical state or other factors 
Unlikely: 
• Poor temporal relationship to the study drug  
• Patient’s clinical state is likely to have an association with the effect 
Unrelated: 
• Definitely not associated with the study drug administered 
“Definite”, “Probable” and “Possible” events are regarded as AEs that cannot be denied a 
causal relationship to the study drug, that will be handled as “related to the study drug” for 
reporting purposes, and “Unlikely” and “Unrelated” events are regarded as AEs that can be 
denied a causal relationship to the study drug, that will be handled as “not related to study drug” 
for reporting purposes.

This timeframe also applies to additional new information (follow-up) on previously forwarded 
SAE reports.  For all SAEs, the investigator is obligated to pursue and provide information to 
the sponsor in accordance with the timeframes for reporting specified above.  In addition, an 
investigator may be requested by the sponsor to obtain specific additional follow-up 
information in an expedited fashion.  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 medications and illnesses must be provided.  In the case of death, a summary of 
available autopsy findings must be submitted as soon as possible to the sponsor.  All SAEs 
occurring in this study requiring expedited regulatory reporting will be evaluated, summarized, 
and reported to investigators.  These SAEs must also be submitted in writing by investigators 
to the institutional review board (IRB). 
 
Pregnancy 
If a patient becomes pregnant during treatment or within 1 month following the last dose of 
the study drug, administration (if still ongoing) must be discontinued and the sponsor is notified 
within 24 hours of investigator awareness of the pregnancy.  For the purposes of this study, 
pregnancy of any patient will be considered an AE but not, in itself, an SAE, and should be 
reported to the sponsor on a pregnancy form rather than an SAE form.  However, if pregnancy 
leads to an SAE for example, a spontaneous abortion or miscarriage resulting in medical 
hospitalization, an SAE form should be completed.  Every attempt must be made to follow the 
pregnancy to resolution, which includes birth or termination of the pregnancy.  If the 
information is available, the resolution must be reported to the sponsor on a pregnancy form.  
If possible, births should be followed by the investigator for 8 weeks for observation of any 
congenital abnormalities, and any such abnormalities should be reported within 24 hours of 
investigator awareness of the observation to the sponsor. 
Pregnancy of a male patient’s partner will not be considered an AE, and the male patient should 
not be withdrawn from the study.  If a male patient’s partner becomes pregnant during the 
specified time period (from first dose until 3 months after the last dose), the investigator will 
inform the sponsor within 24 hours of investigator awareness of the pregnancy, as well as the 
IRB, as appropriate, and will provide appropriate medical follow-up, if agreed to by the partner. 
 
Overdose 
Overdose is defined as administration to the patient of a dose of test article that exceeds by 
more than 40 mg/dose or 80 mg/week. 
Any overdose of HBI-8000 should be reported via an SAE form within 24 hours of investigator 
awareness of the overdose to the sponsor, regardless of association with an AE.  In the case 
that the overdose did not result in an AE, the investigator should report this as “overdose, no 
AE” on the SAE form and specify the intended amount, as well as the actual amount, of drug 
administered. 

 
 
 
Page 42 of 83 
 
 
 
Follow-Up of Adverse Events 
Patients should be asked to specifically describe any signs, symptoms, or AEs (regardless of 
relationship to therapy) they may notice prior to the start of the study or thereafter.  At a 
minimum, patients should be asked to report AEs at each visit to the study site.  Conditions 
that the patient experienced prior to informed consent should be recorded in the medical history 
section of the eCRF.   
Follow up of an “overdose” should include continued monitoring of all protocol-specific 
laboratory results, including chemistry and hematology, using the protocol-specified time 
points for laboratory tests, with the exception that an additional full series of chemistry, 
hematology, and coagulation tests, a full physical examination, vital signs, and ECG should be 
conducted within 24 hours of investigator awareness of that the patient received an “overdose”.  
Following this additional ad hoc re-evaluation, the investigator should use his or her medical 
judgment in deciding whether additional supplemental medical treatment is needed to treat 
adverse medical consequences of the overdose.  Also after the ad hoc re-evaluation, the 
investigator should use his or her medical judgment in deciding whether additional 
supplemental monitoring is needed to track resolution of any AEs or other abnormal findings 
to the point of resolution to a CTCAE Grade 1 AE. 
 
Clinical Laboratory Evaluations 
Clinical laboratory tests, fasting or post meal, will be reviewed for results of potential clinical 
significance at all time points throughout the study.  The abnormality will be graded under 
Investigation category of CTCAE version 4.03 independent of clinical significance.  The 
investigator will evaluate any change in laboratory values.   
Hematology testing will include the following parameters: hemoglobin, hematocrit, red blood 
cell count, white blood cell count with differential, platelet count, coagulation, including 
prothrombin time, activated partial thromboplastin time (aPTT), and International Normalized 
Ratio. 
Serum chemistry testing will include the following parameters: blood urea nitrogen, creatinine, 
AST, ALT, gamma-glutamyl transpeptidase, total bilirubin (including direct fraction if total 
bilirubin is abnormal), lipase, amylase, total protein, albumin, alkaline phosphatase, sodium, 
potassium, calcium, magnesium, random blood glucose, lactate dehydrogenase (LDH), 
creatine kinase MB fraction. 
Urinalysis (glucose, protein, occult blood test) will be performed by dipstick method, and in 
the event of abnormal dipstick results, additional test may be required.  
 
The following information will be captured for blood sample collection in each patient’s eCRF: 
• 
Subject number 
• 
Time and date of dose administration  
• 
Time and date of patient’s most recent ingestion of food prior to dose administration

Vital Signs, Physical Findings and Other Safety Assessments 
Vital signs measurements will include pulse rate and systolic and diastolic blood pressure in a 
seated position of at least 5 minutes. 
Physical examinations will be performed.  A skin assessment will be conducted per the 
standard procedure of the site.  For skin lesions, photograph with an adjacent ruler to indicate 
size will be obtained, if needed. 
ECG are to be 12-lead.  Vital signs measurements should be performed prior to the ECG. 
To assess QTc intervals, 12-lead ECGs in triplicate will be obtained at 3.5 ± 0.5 hours after 
taking study medications on C1D1 and C2D1.  The patient should be in seating position for 5 
minutes before the 1st ECG is obtained, followed by 2nd and 3rd ECGs with 5 ± 2 minutes 
between ECG measurements. 
 
Pharmacokinetics 
Pharmacokinetic sampling for population PK will be performed as detailed in Table 4:   of 
Appendix A. 
Blood samples (2 mL) will be drawn into evacuated tubes containing dipotassium ethylene 
diaminetetra acetic acid.  Each sample will be inverted several times and then placed 
immediately into an ice bath.  Within 30 minutes of sampling, tubes must be centrifuged at 
1,000 × g at 4oC for 5 minutes.  Plasma fractions will then be transferred in 200 μL aliquots 
into 2 cryogenic vials.  The cryogenic vials will be labeled as A or B, plus the unique subject 
number, collection time, and date before being frozen.  Samples will be placed and stored 
at -70oC within 30 minutes of transfer to the cryogenic vial.  The original sample for PK 
analysis (A) and the duplicate sample (B) will be stored at -70°C.  For each patient participating 
PK study, PK (A) samples from Cycles 1 and 2 could be shipped together after Cycle 2 Day 1.  
The site could also ship all samples (Cycles 1 to 6) from each individual patients in one 
shipment.  Samples from several patients could be batched together for shipment as well.  The 
shipment for back-up samples (B) would be handled similarly.  PK samples (A) and samples 
(B) will be shipped to 
. 
Details of sample collection, handling, storage, and transport methodology will be provided to 
the investigator in the laboratory manual. 
The following information will be captured for blood sample collection in each patient’s 
eCRF: 
• 
Subject number 
• 
Time and date of dose administration (as well as time and date of previous dose 
administration for PK samples collected from Cycle 2 onwards) 
• 
Time and date of each blood sample collected for pharmacokinetic analysis 
• 
Time and date of patient’s most recent ingestion of food prior to dose administration

Blood Volume 
The total blood volume for each patient to be collected at screening is approximately 20 mL.  
Blood volume collected for safety tests on Days 1, 8, 15, and 22 of Cycle 1 will be 
approximately 30 mL.  Assuming each patients would receive up to 6 Cycles of treatment, 
subsequent cycles will have blood collections for safety tests on Days 1 and 15 of Cycle 2 then 
Day 1 of Cycles 3 to 6.  The total blood collection volume for Cycles 2 to 6 will be 
approximately 58.5 mL.  The total blood collection volume for EoT will be approximately 
6 mL for safety tests.  For patients participating in PK study, blood volume for PK would be 
30 mL for Cycle 1, 15 mL for Cycle 2 and 2 mL pre-dose on Day 1 of Cycles 3 to 6.  For 
patients receiving treatment Cycle 7 and beyond, there will be no PK blood sample except for 
10.5 mL blood for safety tests.  The assumptions are listed in Table 2 and Table 3.

Independent Review  
 
Data Safety Monitoring Board  
A DSMB has been established to monitor the safety observed during the conduct of this study. 
For all patients, weekly safety laboratory tests should be obtained during the first 28 days and 
closely monitored for safety signals, especially the neutropenia and transaminase elevation.  
DSMB consists of 3 oncologists who are experienced in treating patients with PTCL and are 
not associated with this study.  They are assisted by one DSMB statistician.   
DSMB convenes at planned intervals based on patient accrual (see Section 2.6).  Upon 
reviewing cumulative safety data from the study and taking into consideration of state-of-the-
art medical practice, they will advise sponsor for treatment modification including dose 
adjustment, AE management, and continuation of treatment. 
 
Independent Radiology Review 
To ensure consistent radiology method is applied to assess disease response across the entire 
study, designated radiologists will review sequential imaging studies of individual patients.  
They will assign response outcome including best response, dates of initial response and 
progression when applicable, based on Cheson Critieria. They will be blinded to the local 
radiology findings.  Should discrepancy between assessments by independent radiologist and 
site occur, a 2nd independent radiologist will adjudicate by selecting assessment from either 
site or 1st independent radiologist for final analysis.   
 
Central Pathology Review 
To ensure consistent diagnosis of PTCL subtypes, a panel of pathologists with appropriate 
expertise will review pathology slides from archival tumor specimens or biopsy as applicable.  
The techniques, such as immunohistochemistry staining, will be according to standard of 
practice using agreed methodology, no later than the end of study. 
 
 
Independent Overall Efficacy Review 
To ensure consistent overall efficacy review method is applied to assess disease response 
across the entire study, designated independent oncologists will review sequential clinical data 
of individual patients including radiological assessment provided by the independent 
radiological review. They will assign response outcome including best response, dates of initial 
response and progression when applicable, based on Cheson Criteria 2014.

During monitoring visits, entries in the eCRFs will be compared with the original source 
documents (source data verification).  For the following items, this check will be 100%:  
• 
Subject number 
• 
Patient consent obtained 
• 
Patient eligibility criteria (inclusion and exclusion criteria) 
• 
Efficacy variables 
• 
Medical record of AE 
 
Data Management/Coding 
Data generated within this clinical study will be handled according to the relevant SOPs of the 
Data Management and Biostatistics departments of 
. 
Electronic Data Capture (EDC) will be used for this study, meaning that all eCRF data will be 
entered in electronic forms at the study site.  Data collection will be completed by authorized 
study site staff designated by the investigator.  Appropriate training and security measures will 
be completed with the investigator and all authorized study site staff prior to the study being 
initiated and any data being entered into the system for any study patients. 
All data must be entered in English.  The eCRFs should always reflect the latest observations 
on the patients participating in the study.  Therefore, the eCRFs are to be completed as soon as 
possible during or after the patient’s visit.   
The investigator must verify that all data entries in the eCRFs are accurate and correct.  If some 
assessments are not done, or if certain information is not available or not applicable or 
unknown, the investigator should indicate this in the eCRF.  The investigator will be required 
to electronically sign off on the clinical data.   
The monitor will review the eCRFs and evaluate them for completeness and consistency.  The 
eCRF will be compared with the source documents to ensure that there are no discrepancies 
between critical data.  All entries, corrections and alterations are to be made by the responsible 
investigator or his/her designee.  The monitor cannot enter data in the eCRFs.  Once clinical 
data of the eCRF have been submitted to the central server, corrections to the data fields will 
be audit trailed, meaning that the reason for change, the name of the person who performed the 
change, together with time and date will be logged.  Roles and rights of the site staff responsible 
for entering the clinical data into the eCRF will be determined in advance.  If additional 
corrections are needed, the responsible monitor or Data Manager will raise a query in the EDC 
application.  The appropriate study centre staff will answer queries sent to the investigator.  
This will be audit trailed by the EDC application meaning that the name of investigational staff, 
time and date stamp are captured. 
The eCRF is essentially considered a data entry form and should not constitute the original (or 
source) medical records unless otherwise specified.  Source documents are all documents used 
by the investigator or hospital that relate to the patient’s medical history, that verify the 
existence of the patient, the inclusion and exclusion criteria and all records covering the 
patient’s participation in the study.  They include laboratory notes, electrocardiogram (ECG) 
results, memoranda, pharmacy dispensing records, patient files, etc. 

 
 
 
Page 48 of 83 
 
 
The investigator is responsible for maintaining source documents.  These will be made 
available for inspection by the study monitor at each monitoring visit.  The investigator must 
submit a completed eCRF for each patient who receives study medication, regardless of 
duration.  All supportive documentation submitted with the eCRF, such as laboratory or 
hospital records, should be clearly identified with the study and patient number.  Any personal 
information, including patient name, should be removed or rendered illegible to preserve 
individual confidentiality. 
eCRF records will be automatically appended with the identification of the creator, by means 
of their unique UserID.  Specified records will be electronically signed by the investigator to 
document his/her review of the data and acknowledgement that the data are accurate.  This will 
be facilitated by means of the investigator’s unique UserID and password; date and time stamps 
will be added automatically at time of electronic signature.  If an entry on an eCRF requires 
change, the correction should be made in accordance with the relevant software procedures.  
All changes will be fully recorded in a protected audit trail, and a reason for the change will be 
required. 
Adverse events will be coded using Medical Dictionary for Regulatory Activities (MedDRA) 
Version 21.1 Concomitant medications will be coded using WHO-DDE.  Concomitant 
diseases/medical history will be coded using MedDRA. 
 
Retention of Records 
Records and documents pertaining to the conduct of this study and the distribution of IMP, 
including eCRFs, ICFs, laboratory test results, and medication inventory records, must be 
retained by the Principal investigator (Japan: Head of study site) for at least 15 years after 
completion or discontinuation of the study, or for the length of time required by relevant 
national or local health authorities, whichever is longer. After that period of time, the 
documents may be destroyed, pertinent to local regulations.  No records may be disposed of 
without the written approval of the sponsor.  Written notification should be provided to the 
sponsor prior to transferring any records to another party or moving them to another location. 
 
Quality Assurance Audit 
Study sites, the study database and study documentation may be subjected to Quality 
Assurance audit during the course of the study by the sponsor or delegate(s) on behalf of the 
sponsor.  In addition, inspections may be conducted by regulatory bodies at their discretion.  
 
Site Audits 
The principal investigator or sub-investigators and institutions involved in the study will permit 
study-related monitoring, audits, IRB review, and regulatory inspection(s) by providing direct 
access to all study records.  In the event of an audit, the principal investigator or sub-
investigator agrees to allow the sponsor, its representatives, or the regulatory agencies access 
to all study records. 

 
 
 
Page 49 of 83 
 
 
The investigator should promptly notify the sponsor or its authorized representative of any 
audits scheduled by any regulatory authorities and promptly forward copies of any audit reports 
received to the sponsor or its authorized representative.

5.0 STATISTICS 
 
General Statistical Considerations 
Protocol HBI-8000-203 is an open-label, Phase 2b pivotal study evaluating HBI-8000 for 
regulatory approval in Japan and South Korea for the indication of relapsed or refractory PTCL. 
The main analysis will be conducted for the purpose of regulatory submission of this product. 
The data cut-off (DCO) for the main analysis is set at the time when the last patient completes 
at least one post-efficacy assessment. The eCRF data by the DCO needs to be cleaned to have 
no unresolved queries. All independent reviews (including the Central Pathology Review, the 
independent radiological review, the Independent Overall Efficacy Review and review by the 
Data Safety Monitoring Board) by the DCO need to be completed before the main analysis. 
The data after the main analysis will be provided at the end of the study as a supportive material.  
Statistical analysis for all safety, efficacy, and PK parameters will be primarily descriptive in 
nature. Categorical variables will be summarized by frequency distributions (number and 
percentages of patients), continuous variables will be summarized by mean, standard deviation, 
median, minimum, maximum, and time-to-event variables will be summarized using Kaplan-
Meier methods and figures for the estimated median time.   
All analyses, summaries, and listings will be performed using SAS software (version 9.3 or 
higher) 
A detailed methodology for summary and statistical analysis of the data collected in this trial 
will be documented in a Statistical Analysis Plan (SAP) that will be dated and maintained by 
HUYABIO.  The SAP may modify the plans outlined in the protocol; however, any major 
modifications of the primary endpoint definition and/or its analysis will also be reflected in a 
protocol amendment.  
 
Determination of Sample Size 
For efficacy determination, 40 patients evaluable for efficacy per protocol criteria are required.  
To ensure meeting this target, an estimated 50 to 60 patients would be enrolled in anticipation 
that some patients may not complete study treatment.  Enrolled patients will be treated with 
the starting dose of 40 mg BIW to provide an assessment of tumor response as well as 
additional safety data.  It is planned that 34 to 40 patients (27 evaluable patients) will be 
coming from Japan and 16 to 20 patients (13 evaluable patients) will be coming from Korea. 
The target best ORR for this study is 30%, on the basis of the ORR results that were obtained 
in study TG0902CDM.  The 95% confidence interval (CI) for an ORR of 30% at a sample size 
of N=40 is expected to be between 15.8% and 44.2%. 
The power for showing the response rate >10% at 5% two-sided alpha in 40 patients is 89%. 
The 95% confidence interval for an objective response rate (assumed to be 30%) at various 
sample sizes are shown below:

Treatment Assignment and Blinding 
This is an open-label, sequential enrollment study; therefore, no randomization or blinding 
procedures will be performed. 
 
Replacement of Patients 
Patients who are lost to follow up or withdraw consent for study participation prior to receiving 
HBI-8000 or who withdraw in Cycle 1 for reasons unrelated to drug toxicity or PD will be 
replaced.   
 
Populations for Analysis 
 
Safety Population 
The safety analyses population will include all patients who receive at least one dose of 
HBI-8000.  The safety analyses population will be the primary population for evaluating 
treatment administration / compliance and safety in the study. 
 
Efficacy Population 
Efficacy should be analyzed using FAS and PPS.  
The FAS is defined as Patients meeting all eligibility criteria and having received at least one 
dose of study medication, and at least one efficacy assessment of disease with either imaging 
studies or clinical examination after receiving study medication. 
The PPS is defined as Patients meeting all eligibility criteria and having completed Cycle 1 
treatment or discontinued study treatment during cycle 1 due to clinical PD. It should be noted 
that the PPS includes subjects who discontinue within Cycle 1 due to clinical PD without 
imaging studies to assess disease status.  
 In addition, Patients who are assessed as Non-PTCL by the central pathology review 
committee should be excluded from the FAS and PPS for efficacy. The non-PTCL subjects 
will be included in safety analysis for the study. 

 
 
 
Page 52 of 83 
 
 
The primary efficacy analysis is conducted in the PPS. The Efficacy analysis using the FAS 
will be also reported. 
 
 
Pharmacokinetic Population 
All patients who have pretreatment baseline and at least 1 blood sample on study providing PK 
data for HBI-8000. 
 
Patient Disposition 
Data tabulations will summarize the following patient numbers: 
• Enrolled 
• HBI-8000 treatment dose received 
• Evaluable for safety and efficacy 
• Protocol violations 
• Protocol completions 
• Withdraw from study due to: 
 Adverse event 
 Physician’s recommendation 
 Withdrew consent 
 Lost to Follow-up 
 Other reasons as collected on the eCRF 
 
Patient Characteristics 
Demographic and baseline characteristics of patients will be summarized using descriptive 
statistics: 
• Age 
• Gender 
• Race 
• Ethnicity 
• ECOG Performance Status 
• Prior therapies 
• Other baseline characteristics as collected on the eCRF 
 
Concomitant Medications 
The number and proportion of patients using different concomitant medications will be 
tabulated and summarized by WHO Drug anatomical therapeutic chemical (ATC) 
classification system and preferred term. 

 
 
 
Page 53 of 83 
 
 
 
Treatment Administration 
Study drug administration will be described in terms of the total number of cycles administered, 
the median (range) of cycles administered, dose intensity, and reasons for the deviations from 
planned therapy. 
 
Efficacy Analysis 
The efficacy endpoints are the following: 
Primary Endpoint:  
• ORR(CR + PR)  
Secondary Endpoint: 
• ORR by disease subtype (see Section 2.5.1) 
• Median duration of PFS  
• Median DOR  
Exploratory Endpoint 
• Median duration of OS 
Response rate endpoints (ORR and ORR by disease subtype) will be summarized by number 
and percentage of patients meeting the definition of ORR along with the corresponding exact 
95% CI.  Tumor response as assessed by imaging studies will be adjudicated by independent 
radiology reviewers.  Tumor lesions, such as skin lesion, that cannot be monitored by imaging 
studies will determined by independent oncology reviewers and contributed to overall disease 
response assessment.  Both investigators reported and independently adjudicated outcomes 
will be reported.  Primary analysis will be based on results from imaging studies and clinical 
data confirmed by Independent Central Review.  Results from investigator assessment will 
also be reported. In addition, the ORR will be analyzed according to histology subtypes of 
PTCL.  The subtypes reported by Central pathology review for each patient will be used for 
such analysis. 
Time-to event endpoints (PFS, DOR, and OS) for entire study population will be summarized 
by Kaplan-Meier methods (median, 95% CI, number of events, number censored and Kaplan-
Meier figures). 
 Safety Analysis 
All patients who receive one dose (any amount) of HBI-8000 will be included in the summaries 
and listings of safety data. Overall safety profile and tolerability will be characterized by type, 
frequency, severity, timing, duration, and relationship of study therapy of AEs and laboratory 
abnormalities. 

 
 
 
Page 54 of 83 
 
 
 
Adverse Events 
Adverse events will be classified using the MedDRA classification system version 19.0 or 
higher.  The severity of the toxicities will be graded according to the NCI CTCAE version 4.03. 
In all summaries, emphasis will be placed on treatment emergent adverse events (TEAEs), 
namely, those with initial onset or that worsen in severity after the first dose of HBI-8000.  
TEAEs will be summarized by the frequency of patients experiencing TEAEs corresponding 
to body systems and MedDRA preferred term and by worst NCI CTCAE (version 4.03) grade.  
Summaries will also be provided of treatment related TEAEs, namely, those judged by the 
investigator to be related or likely related to HBI-8000. 
TEAEs resulting in discontinuation of HBI-8000 treatment or withdrawal from the study, 
Grade 3 or higher, SAEs, and deaths on-study will be tabulated. 
 
Laboratory Tests 
Laboratory data will be summarized for the observed values at each scheduled assessment, 
together with the corresponding changes from baseline (the value obtained prior to dosing on 
Day 1 of Cycle 1) using descriptive statistics.  
For those analyses with CTCAE grades, abnormal laboratory values will be summarized by 
shift tables displaying numerical values and percentages classified by Baseline grade (e.g., 
grade prior to dosing on Day 1 of Cycle 1) and maximum grade on treatment.  All laboratory 
data will be presented in listings.  
 
ECGs 
Serial ECGs will be performed to evaluate the potential effects of the study drug on the heart. 
The ECG parameters (PR interval, QRS duration, QT, QTc and QTcF) will be summarized 
descriptively for each time point for both the observed values and the change from Baseline to 
each post-baseline time point.  The number and percentage of patients with QT or QTc (QTcF) 
outlier values (at any post-baseline time point), as defined in ICH E14, will be summarized. 
 
Vital Signs and Physical Findings 
Vital signs data will be summarized by the observed valued at each scheduled assessment, 
together with the corresponding changes from Baseline using descriptive statistics. 
Physical findings will be presented in data listings.  
 
Interim Analysis 
No interim analysis for efficacy is planned for this Phase 2b study.  

 
 
 
Page 55 of 83 
 
 
 Pharmacokinetic Analysis 
In patients participating in PK study, peripheral blood will be sampled at specified time points.  
Plasma concentration of HBI-8000 will be listed and summarized using descriptive statistics.  
PK data collected in this study will be combined with PK data collected from other studies and 
a population PK analysis will be performed.  Results of the population PK analysis will be 
presented in a report separate from the CSR.

6.0 ETHICS 
 
Institutional Review Board or Independent Ethics Committee 
The protocol, ICF and any other written information and/or materials to be provided to the 
patients and the amendments (as required by local regulations) should be reviewed and 
approved by the IRB/Independent Ethics Committee (IEC).  The sponsor’s authorized 
representative should be provided with documentation of IRB/IEC approval of the protocol 
and informed consent before the study may begin at the study center(s). 
The only circumstance in which an amendment may be initiated prior to the sponsor and 
IRB/IEC approval is where the change is necessary to ensure the safety of the patients.  In that 
case, the investigator must document the change and notify the sponsor and IRB/IEC in writing 
immediately after the implementation. 
The investigator should submit written summaries of the study status for review by the 
IRB/IEC annually, or more frequently if requested by the IRB/IEC.  Upon completion of the 
study, the investigator will provide a brief report of the outcome of the study, if required.  The 
sponsor and/or the sponsor’s authorized representative will handle the distribution of any of 
these documents to the national regulatory authorities. 
 
Ethical Conduct of the Study 
This study will be conducted and the informed consent will be obtained according to the ethical 
principles stated in the Declaration of Helsinki (48th General Assembly, Somerset West, 
Republic of South Africa, October 2008 [or current version]), the applicable guidelines for 
GCP (CPMP/ICH/135/95), or the applicable drug and data protection laws and regulations of 
the countries where the study will be conducted. 
Good Clinical Practice is an international ethical and scientific quality standard for designing, 
conducting, recording and reporting studies that involve the participation of human patients.  
The study will be conducted in compliance with GCP and the applicable national regulations 
so as to assure that the rights, safety and well-being of the participating study patients are 
protected consistent with the ethical principles that have their origin in the Declaration of 
Helsinki. In Japan, the study shall be conducted in accordance with Good Post-marketing Study 
Practice (GPSP) as well as GCP after the PTCL approval. 
 
Patient Information and Informed Consent 
The ICF will be used to explain the risks and benefits of study participation to the patient in 
simple terms before the patient will be entered into the study.  The ICF contains a statement 
that the consent is freely given, that the patient is aware of the risks and benefits of entering 
the study, and that the patient is free to withdraw from the study at any time.  Written consent 
must be given by the patient and/or the legal guardian, after the receipt of detailed information 
on the study.

The investigator is responsible for ensuring that informed consent is obtained from each patient 
or the legal guardian and for obtaining the appropriate signatures and dates on the informed 
consent document prior to the performance of any protocol procedures and prior to the 
administration of study medication.  The investigator will provide each patient with a copy of 
the signed and dated consent form.   
Whenever important new information becomes available that may be relevant to the patient’s 
consent, the approved by the IRB/IEC, revised information will be provided to each patient in 
the trial for signing and dating.  The investigator will explain the changes to the previous 
version. 
 
Patient Data Protection 
The ICF will incorporate (or, in some cases, be accompanied by a separate document 
incorporating) wording that complies with relevant data protection and privacy legislation.  
Information about study subjects will be kept confidential and managed according to the 
regulatory requirements.

7.0 STUDY ADMINISTRATION 
 
Administrative Structure 
The administrative structure and study organization is presented in Protocol addendum. 
 
Data Handling and Record Keeping 
It is the investigator’s responsibility to maintain essential study documents (protocol and 
protocol amendments, completed eCRFs, signed ICFs, relevant correspondence, and all other 
supporting documentation).  The study site should plan on retaining such documents for 
approximately 15 years after study completion.  The study site should retain such documents 
until at least 2 years after the last approval of a marketing application in an ICH region and 
until there are no pending or contemplated marketing applications in an ICH region or at least 
2 years after the formal discontinuation of clinical development of the investigational product.  
These documents should be retained for a longer period if required by the applicable regulatory 
requirements or the hospital, institution, or private practice in which the study is being 
conducted.  Patient identification codes (patient names and corresponding study numbers) will 
be retained for this same period of time.  These documents may be transferred to another 
responsible party, acceptable to sponsor, who agrees to abide by the retention policies.  Written 
notification of transfer must be submitted to the sponsor and/or the sponsor’s authorized 
representative.  The investigator must contact the sponsor and/or the sponsor’s authorized 
representative prior to disposing of any study records.   
The U.S. FDA regulations (21 CFR §312.62[c]) and the ICH Guideline for GCP (see 
Section 4.9 of the guideline) require that records and documents pertaining to the conduct of 
this study and the distribution of study drug, including eCRFs, consent forms, laboratory test 
results, and medication inventory records, must be retained by the principal investigator for 
15 years after the last marketing application approval in an ICH region or after at least 15 years 
have elapsed since formal discontinuation of clinical development of the investigational drug.   
No records should be disposed of without the written approval of the sponsor and/or the 
sponsor’s authorized representative.  
For studies conducted outside the United States under a U.S.  IND, the principal investigator 
must comply with U.S.  FDA investigational new drug regulations and with those of the 
relevant national and local health authorities. 
 
Direct Access to Source Data/Documents 
The investigator will prepare and maintain adequate and accurate source documents to record 
all observations and other pertinent data for each patient enrolled into the study.   
The investigator will allow the sponsor, the sponsor’s authorized representative(s), and 
authorized regulatory authorities to have direct access to all documents pertaining to the study, 
including individual patient medical records, as appropriate.

Investigator Information 
 
Investigator Obligations 
This study will be conducted in accordance with the ICH Harmonized Tripartite Guideline for 
GCP (GCP, 1997; the US CFR Title 21 parts 50, 56, and 312; European Legislation; and 
Ministerial Ordinance on the Standards for the Implementation of Clinical Studies on 
Pharmaceutical Product [Japan GCP]) and the ethical principles that have their origin in the 
Declaration of Helsinki, and the applicable regulatory requirements of each region. In Japan, 
the study shall be conducted in accordance with GPSP as well as GCP after the PTCL approval. 
The investigator agrees to conduct the clinical study in compliance with this protocol after the 
approval of the protocol by the IEC/IRB in compliance with local regulatory requirements.  
The investigator and the sponsor will sign the protocol to confirm this agreement. 
 
Protocol Signatures 
After reading the protocol, each investigator will sign the protocol signature page and send a 
copy of the signed page to the sponsor or representative (Appendix G).  By signing the protocol, 
the investigator confirms in writing that he/she has read, understands and will strictly adhere 
to the study protocol and will conduct the study in accordance with ICH Tripartite Guidelines 
for Good Clinical Practice and applicable regulatory requirements.  In Japan, the investigator 
will conduct the study in accordance with GPSP as well as GCP after the PTCL approval. The 
study will not be able to start at any site where the investigator has not signed the protocol. 
 
Publication Policy 
The data generated by this study are confidential information of the sponsor.  The sponsor will 
make the results of the study publicly available.  The publication policy with respect to the 
investigator and study site will be set forth in the Clinical Trial Agreement. 
 
Financing and Insurance  
The sponsor has obtained liability insurance, which covers this study as required by local law 
and/or national regulations and/or ICH guidelines whichever is applicable.  The terms of the 
insurance will be kept in the study files.

Cycle/Day designation is based on actual calendar days after the first dose.  All visits and assessments may be performed ± 7 days to 
accommodate unforeseen delays, holidays, or vacations.  
b 
“End of Treatment” visit should be conducted 30 ± 3 days after the last dosing of the study drug, before the initiation of new cancer 
treatment or before the initiation of administration of commercial product of HBI-8000, whichever is earlier.  
c 
Survival data will be collected every 3 months ± 2 weeks after End of Treatment until death or the end of the study, defined as timing 
that the last Japanese subject initiates administration of the commercial product of HBI-8000. 
d 
Drug administration BIW for 4 weeks ; On the days of scheduled visits that is the same as the dosing scheduled day, patient should take 
study drug after receiving confirmation from investigator to continue study treatment.  
e 
Dose adjustments based on hematological and non-hematological criteria.   
f 
Pulse rate, diastolic and systolic blood pressure in seated position of 5 minutes.  On days when ECGs are taken, vital signs to be taken 
shortly prior to ECG recording.  
g 
Pre-dose and post dose at 3.5 ± 0.5 hours in triplicates, 5 ± 2 minutes between 1st and 2nd, 2nd and 3rd ECGs, on Day 1 of Cycles 1 and 
2.

l 
Only for women of childbearing potential, including those who have had a tubal ligation.  Confirmatory test at the Cycle 1 Day 1 
(C1D1) visit should be done before dosing at the local laboratory.  If Serum pregnancy test result cannot be obtained on the same day 
before dosing, urine pregnancy test should be conducted additionally and the result should be confirmed before dosing.  Only at EoT 
visit, Serum and Urine are both acceptable.  
m 
Complete tumor assessment of all lesions by radiographic or other modality.  Baseline bone marrow test (aspiration or biopsy) is 
required.  Response and progression for PTCL will be evaluated according to the revised criteria for response assessment in lymphoma 
[Cheson 2014], however, PET-CT is not required but encouraged.  Skin lesions, if present, will be assessed by mSWAT and contribute 
to overall tumor response determination by investigators.  Assessment of tumor response will be scheduled by end of the 8th week, then 
every 8 weeks (± 1 week) from C1D1, However, if a patient develops clinical signs and symptoms of disease progression, or 
unacceptable toxicity occurs, tumor assessment may be performed sooner as needed.  If a patient discontinues study treatment before 
disease progression (PD) is recorded, and if their last tumor assessment was >30 days earlier from EoT visit, tumor assessment should 
be performed at EoT.  In these patients, further tumor assessments are to be performed approximately every 3 months ± 2 weeks until 
PD or the start of new cancer therapy whichever occurs first, unless consent to study participation is withdrawn or by completion of the 
whole study. If subjects cannot visit their study site for this examination due to COVID-19 situation, investigators can skip the 
examination, and the assessment is to be performed approximately every 6 months ± 2 weeks. In this case, the investigator should 
document that fact in the medical record. 
n 
PK sampling on C1D1 pre-dose and 1 h (± 15 mins), 2h (± 15 mins), 3h (± 15 mins), 4h (± 15 mins), 5h (± 30 mins), and 7h  (± 30 
mins), then 24 ± 1, 48 ± 1 and 72 ± 1 hours in consenting patients; and C2D1 pre-dose and 1 h (± 15 mins), 2h (± 15 mins), 3h (± 15 
mins), and 4h (± 15 mins). 
o 
Day 1 of cycles 3 to 6 pre-dose PK sample only.  
p 
Some of the pre-dose assessments except vital signs and ECG may be performed one day before C1D1 to accommodate scheduling 
requirements in the hospital.

Appendix D: Method of Efficacy Assessment 
Overall response will be assessed according to recommendations for Hodgkin and nonHodgkin 
lymphoma developed in International Conference on Malignant lymphoma in Lugano, 
Switzerland, 2011, and published in 2014 (Cheson 2014).  Patients will have pretreatment 
assessment at screening and postdose evaluations on Day 1 of subsequent cycles.  Imaging 
studies such as CT to evaluate nodal and extranodal lesions will performed at end of the 8th 
weeks, then every 8 weeks (± 1 week) from C1D1.  However, if a patient develops clinical 
signs and symptoms of disease progression, or unacceptable toxicity occurs, tumor assessment 
may be performed sooner as needed.  If a patient discontinues study treatment before disease 
progression (PD) is recorded, and if their last tumor assessment was > 30 days earlier from 
EoT visit, tumor assessment should be performed at EoT.  In these patients, further tumor 
assessments are to be performed approximately every 3 months ± 2 weeks until PD or the start 
of new cancer therapy whichever occurs first, unless consent to study participation is 
withdrawn.  
 
Evaluation at Screening 
At screening, physical examination is not considered quantitative assessment of lesion size.  
Disease lesion(s) will be evaluated by imaging studies (CT or PET-CT), bone marrow test 
(aspiration or biopsy), and skin evaluation.  In case gastrointestinal lesion is suspected, 
endoscopy and biopsy (as needed) will be performed. 
All lesions are categorized into the following: 
• 
lesion which can be used for efficacy assessment (hereinafter, evaluable lesion) 
• 
lesion which cannot be used for efficacy assessment (hereinafter, non-evaluable lesion) 
In addition, evaluable lesions are categorized into the following: 
• 
measurable lesion 
• 
nonmeasurable lesion 
Next, target lesions (up to 6 lesions) are selected from measurable lesions. 
Nonmeasurable lesions and other measurable lesions are deemed as non-target lesions.

Figure 3:  Selection of Lesions 
 
 
Imaging 
Before the start of study drug administration, evaluation by CT images of neck, chest, abdomen, 
and pelvis that are taken by a pitch of 5 mm preferable (as for neck image, a pitch of 2.5  to 5 
mm will be preferred) will be performed.  Same imaging techniques should be used at baseline 
and on study assessment.  PET-CT is encouraged, but not required. 
 
 
Definition of lesion which can be used for efficacy assessment (evaluable lesion) 
Nodal lesion with the size > 1.5 cm by longest transverse dimension (LDi) on sectional image 
(e.g, enlarged lymph node) at screening and extranodal lesion which can be followed by 
imaging are defined as evaluable lesion. 
 
 
Definition of lesion which cannot be used for efficacy assessment (non-
evaluable lesion) 
Non-evaluable lesion is defined as nodal lesion with LDi ≤ 1.5 cm on sectional image of CT 
at screening and extranodal lesion that cannot be followed by imaging. 
 
 
Definition of Measurable Lesion (common with nodal and extranodal lesion) 
In evaluable lesions, measurable lesion is defined as the lesion that meets both following 
criteria: 

 
 
 
Page 71 of 83 
 
 
• 
The LDi > 1.5 cm on sectional image of CT for nodal lesion; and > 1.0 cm for extranodal 
lesion 
• 
Definitely measurable by 2 perpendicular dimensions (LDi and its perpendicular 
dimension) on sectional image of CT 
 
 
Definition of Non-measurable lesion 
In evaluable lesions, non-measurable lesion is defined as the lesion that meets any of the 
following criteria: 
• 
Enlarged lymph node:  Lesion with the LDi > 1.5 cm on sectional image of CT, but not 
definitely measurable by 2 dimensions (LDi and its perpendicular dimension) 
• 
Extranodal lesion:  All lesions that can be followed by imaging, but do not meet the 
definition of measurable lesion 
 
 
Nodes or Extranodal Lesions That Split When Disease Is Responding  
If a conﬂuent nodal mass splits into several discrete nodes, the individual product of the 
perpendicular diameters (PPDs) of the nodes should be summed together to represent the 
PPD of the split lesion; this PPD is added to the sum of the PPDs of the remaining lesions to 
measure response.  If subsequent growth of any or all of these discrete nodes occurs, the 
nadir of each individual node is used to determine progression (as if each individual node 
was selected as a target lesion at baseline). 
 
Nodes or Extranodal Lesions That Become Conﬂuent When Disease Is 
Progressing  
If a group of target lymph nodes becomes conﬂuent, the PPD of the current conﬂuent mass 
should be compared with the sum of the PPDs of the individual nodes, with more than 50% 
increase in the PPD of the conﬂuent mass compared with the sum of individual nodes necessary 
to indicate progressive disease.  The LDi and shortest diameter are no longer needed to 
determine progression. 
 
Selection of Target Lesions 
Target lesions are selected from measurable lesions, which can be nodal lesion and extranodal 
lesion, along with the following criteria: 
• 
Lesions that is suitable to be measured exactly and continuously by the same method. 
• 
Up to 6 lesions in descending order by LDi length on sectional image of CT.  If measurable 
lesions are less than 6, all measurable lesions are selected. 
• 
Nodes should preferably be from disparate regions of the body and should include, where 
applicable, mediastinal and retroperitoneal areas. 
 
The lengths of LDi (cm) and the largest diameter (cm) which is perpendicular to LDi are 
measured, and their product (PPD) is the cross product of LDi and the PPD for the lesion.  The 
sum of PPD of all target lesions (SPD) will be calculated at screening. 

 
 
 
Page 72 of 83 
 
 
 
Definition and Selection of Non-target Lesion 
Measurable lesions that are not selected as target lesion and non-measurable lesions are defined 
as non-target lesions. 
Non-target lesions are separately evaluated as nodal non-target lesions and extranodal 
nontarget lesions.  If any tumor lesions are found through gastrointestinal endoscopy, the lesion 
is to be evaluated as extranodal non-target lesion. 
 
Evaluation of Skin Lesion 
In case tumor lesion on skin exists, the lesion is considered as non-target.  Skin lesion which 
can be monitored for efficacy should be followed.  Investigators can consult dermatologists in 
sites or clinics if needed. 
If it is difficult to determine whether or not skin lesion exist by inspection, biopsy will be 
performed to diagnose histopathologically.   
Skin lesions will be followed according to Severity-Weighted Assessment Tool (Stevens et al 
2002): Revised Edition (mSWAT). 
 
Evaluation by Modified Severity-Weighted Assessment Tool (mSWAT) 
(Olsen et al. 2011) 
A total of body surface area (%BSA) of each part is defined in Table 6and Figure 4 (e.g., head 
7, neck 2, and anterior trunk 13) in which total body surface area of human is defined as 100. 
After %BSA of each type of lesion (patch, plaque, tumor mass, or ulcer) and normal skin is 
assessed by body parts, percentage of total body surface area (%TBSA) of each type of lesion 
will be calculated by adding %BSA of total body by type of lesion.  In addition, mSWAT score 
is defined as summation (0 to 400) of product of %TBSA and each summation factor (see the 
following formula). 
mSWAT score = (%TBSA of patch ×1) + (%TBSA of plaque × 2) + (%TBSA of tumor mass 
and ulcer × 4)

Presence or absence of splenomegaly  
Presence or absence of splenomegaly which are considered to be caused by infiltration of 
lymphocyte is assessed by CT.  To be considered positive, the vertical length of spleen must 
be >13 cm by CT.  
 
Evaluation of infiltration to bone marrow 
Infiltration to bone marrow will be evaluated by PET-CT or bone marrow aspiration or 
biopsy.  When bone marrow evaluation is selected, the results will be categorized into the 
following: 
• Positive: Presence of apparent malignant findings including infiltration of abnormal 
lymphocyte and abnormality in assembly 
• Undetermined: Increase of lymphocyte aggregation without infiltration of abnormal 
lymphocyte or abnormality in assembly 
• Negative: Absence or minimal findings of lymphocyte aggregation. 
 
Postdose Evaluation  
Imaging studies will be performed by the same method as screening. 
 
 
Evaluation of target lesion 
Efficacy for target lesion will be assessed by calculating reduction rate (A) and growth rate 
(B) of the SPD according to the following formula:

*A score of 3 in many patients indicates a good prognosis with standard treatment, especially if at 
the time of an interim scan. However, in trials involving PET where de-escalation is investigated, it 
may be preferable to consider a score of 3 as inadequate response (to avoid undertreatment). Measured 
dominant 
lesions: Up to 6 of the largest dominant nodes, nodal masses, and extranodal lesions 
selected to be clearly measurable in two diameters. Nodes should 
preferably be from disparate 
regions of the body and should include, where applicable, mediastinal and retroperitoneal areas. 
Nonnodal lesions include those in solid organs (eg, liver, spleen, kidneys, lungs), GI involvement, 
cutaneous lesions, or those noted on palpation. Nonmeasured lesions: Any disease not selected as 
measured, dominant disease and truly assessable disease should be considered not measured. These 
sites include any nodes, nodal masses, and extranodal sites not selected as dominant or measurable 
or that do not meet the requirements for measurability but are still considered abnormal, as well as 
truly assessable disease, which is any site of suspected disease that would be difficult to follow 
quantitatively with measurement, including pleural effusions, ascites, bone lesions, leptomeningeal 
disease, abdominal masses, and other lesions that cannot be confirmed and followed by imaging. 
In Waldeyer’s ring or in extranodal sites (eg, GI tract, liver, bone marrow), FDG uptake may be 
greater than in the mediastinum with complete metabolic response, but should be no higher than 
surrounding normal physiologic uptake (eg, with marrow activation as a result of chemotherapy 
or myeloid growth factors).

Evaluation of skin lesion by mSWAT 
Criteria for assessment for tumor shrinkage effect on skin lesion by mSWAT are as 
following: 
• CR: 100% clearance  of skin lesion* 
• PR: 50 to 99% clearance of skin disease from baseline without new lesion 
• SD: < 25% increase to < 50% clearance in skin disease from baseline without 
appearance of new lesion. 
• PD: ≥25% increase in skin disease from baseline or New tumor mass** or Loss of 
response: in those with complete or partial response, increase of skin score of greater 
than the sum of nadir plus 50% baseline score.  
* In case distinguish between residual lesion and normal skin tissue is difficult, CR is 
determined after confirming disappearance of skin lesion by biopsy. 
* * tumor mass : at least 1 cm diameter solid or nodular lesion with evidence of depth 
and/or vertical growth

Appendix E:  Blood Sample Collection 
 
Caution for use concerning vacuum blood-collection tubes 
 
The test kits provided for the clinical study include vacuum blood-collection tubes.  Since reflux may 
occur due to inappropriate handling of a vacuum blood-collection tube resulting in the contents and/or 
contaminants in the blood-collection tube to flow into the patient’s body, the notifications (Notification 
No. 1117001 of PFSB, “Voluntary inspection of caution for use and other relevant information 
concerning vacuum blood-collection tube”, dated 17 November 2003 and Notification No. 0104001 of 
PFSB, “Additional information on the caution for use concerning vacuum blood-collection tubes” dated 
04 January 2005 issued by Director of Safety Division) were released to draw your attention to usage 
of vacuum blood-collection tubes.  Please pay attention to the precautions listed below and use the 
vacuum blood-collection tubes of this study with care. 
 
1. Caution for use of sterile vacuum blood-collection tubes 
o The temperature of the blood-collection tubes prior to blood draw must be equivalent to 
the room temperature (the inner pressure may change, which could cause the blood in the 
blood-collection tube to flow back into the body along with the contaminants). 
o Do not move, or release the pressure applied on the arm of the patient before removing the 
blood-collection needle (moving the position of, or releasing the pressure applied on the 
arm may cause rapid decrease in the venous blood pressure, which could cause the blood 
in the blood-collection tube to flow back into the body along with the contaminants). 
o After the blood starts flowing into the collection tube, do not apply force on the tube that 
could push it into the blood-collection holder (the inner pressure may change, which could 
cause the blood in the blood-collection tube to flow back into the body along with the 
contaminants). 
o Do not remove the tourniquet after the completion of blood draw unless otherwise the 
blood-collection needle is removed first (changes in the pressure due to removal of the 
tourniquet could cause the blood in the blood-collection tube to flow back into the body 
along with the contaminants). 
o The holder is for single-patient use only, and should be disposed of after each use (the 
holder may be contaminated with the blood, which could cause cross infection). 
o Do not draw blood from extracorporeal circuit or central vein (changes in the pressure 
could cause the blood in the blood-collection tube to flow back into the body along with 
the contaminants). 
 
2. Instruction for operation or usage 
o The temperature of the blood-collection tubes should be equivalent to the room temperature. 
o The puncture site should be disinfected after the tourniquet is applied. 
o The blood-collection tube should be pushed into the holder straight and completely. 
o The blood-collection tube should be removed from the holder as soon as the blood flow 
into the tube stops. 
o Consecutive blood draws should be performed with the holder fixed in place and the 
collection tube replaced. 
o Upon completion of the blood draw, the tourniquet should be kept applied until after the 
collection tube is removed from the holder. 
 
3. Basic cautions of importance 

 
 
 
Page 80 of 83 
 
 
The blood-collection tube and the patient’s arm should point downward at all time during the blood 
draw. 
 
When using a winged needle for blood draw, ensure that the blood-collection tube does not move 
up and down.

Synopsis 
Statistical 
procedure 
Patients considered evaluable for efficacy must 
meet eligibility criteria and have at least one 
post-baseline assessment of efficacy, or who 
discontinue study early due to clinical PD. 
Efficacy should be analyzed by Full analysis set 
(FAS) and Per protocol set (PPS).  Full 
analysis set is defined as patients having 
received at least one dose of study medication

Procedures 
Disease diagnosis including histological subtypes will be confirmed by 
central pathology review conducted by independent pathologists.  A 
patient considered evaluable for efficacy per protocol must have a 
baseline tumor assessment and at least 1 tumor assessment during study 
treatment; have received at least 1 cycle of study drug; and meet all 
eligibility criteria; or have discontinued study early due to clinical PD.  
It is estimated that 40 evaluable patients are adequate to provide efficacy 
assessment. Assuming a 30% ORR in this population of 40 evaluable 
patients, the conclusion would be that there is a 95% chance that the 
ORR in this protocol population would lie between 15.8% and 44.2%.

HBI-8000 inhibits several cancer-associated Class I (HDAC 1, 2, 3) and 
one Class IIb HDAC (isoenzymes 6 and 10) HDACs in the nanomolar 
range and stimulates accumulation of acetylated histones H3 and H4 in 
tumor cells [Ning 2012].

Assessments 
(within 28

Tumor pathology slides will be sent to central laboratory and archived for 
central pathology review that is planned at end of study before efficacy 
analysis.  
Screening assessments will be performed within 28 days prior to Cycle 1 
Day 1 (C1D1). Results of standard-of-care tests or examinations 
performed prior to obtaining informed consent and within 28 days prior to 
C1D1 may be used (and do not need to be repeated for screening unless 
they do not meet the criteria defined in the protocol). 
Tumor Unstained tumor pathology slides will be sent to pathology central 
laboratory and archived stained at the central laboratory.  The images will be 
captured from the slides for central pathology review that is planned at end of 
study to be completed before efficacy analysis.  For patients who do not have 
enough tumor tissue archived, a new biopsy will be requested.  However, 
insufficient tumor tissue in archive or inability to perform new biopsy for any 
reason does not exclude patients from entering this study.  Reasonable efforts 
should be made to support central pathology review. 
Screening assessments will be performed within 28 days prior to Cycle 1 Day 1 
(C1D1).  A pretreatment bone marrow test (aspiration or biopsy) would be 
required.  Results of standard-of-care tests or examinations performed prior to 
obtaining informed consent and within 28 days prior to C1D1 may be used (and 
do not need to be repeated for screening unless they do not meet the criteria 
defined in the protocol).  Similarly, tumor assessment tests <2 weeks outside the 
28-day window in the absence of clinical evidence of PD, the results may be

Prohibited 
Medications 
And Therapy 
Anti-cancer therapy other than study medication is prohibited during the 
study and within the following time intervals prior to the first dose of 
study drug: 4 weeks for anti-cancer chemotherapy and 12 weeks for anti-
cancer monoclonal therapy; 6 weeks for nitrosourea or mitomycin C. 
Drugs known to produce significant QT prolongation or ventricular 
dysrhythmias are prohibited from signing informed consent through the 
EoT assessment. Corticosteroids prescribed for reason other than 
lymphoma is not considered as anti-cancer therapy in this study. 
 
Concomitant administration of HBI-8000 with drugs that significantly 
induce or inhibit CYP3A4, or are metabolized significantly by CYP3A4, 
and have a narrow therapeutic range, including St. John’s wort, are 
prohibited. 
The following drugs are prohibited.  
 
Drugs known to produce significant QT prolongation and ventricular 
dysrhythmias (see Section 9.6)  
Prohibited from signing informed consent through the EoT assessment

2.10.2 
Cautioned 
Medications 
- 
Because the anti-emetic drug Zofran (ondansetron) is well known to prolong 
QTc, it is prohibited on 2 occasions, Cycle 1 Day 1 and Cycle 2 Day 1 when QTc 
test is scheduled.  Starting 24 hours before the QTc test until the QTc test is 
completed on the next day, patient must not take Zofran over a 2-day period.  
Although anti-emetics are rarely needed for HBI-8000, if anti-emetics must be 
used for other medical reason, alternative drug(s) should be used.  If a 5-HT3 
antagonist must be used to manage severe emesis refractory to other medications, 
dosing should be postponed until resolution of underlying medical condition.  
In case it is medically necessary to co-administer drugs that could interfere with 
CYP3A4 activity, investigators should monitor for toxicities and follow the study 
drug dose modifications for toxicity per study protocol.  Also, St. John’s wort 
should be used with caution.

Sulfamethoxazole Trimethoprim use is permitted.  However, when its side 
effects are observed, alternative antibiotics prophylaxis should be considered.

Efficacy 
Endpoint 
Tumor assessments will be performed by imaging modalities. CT, MRI, 
or PET scanning may be used to evaluate lesions in the neck, chest, 
abdomen, and pelvis; and as a baseline evaluation for patients who may 
have brain metastases.  Evaluation of nodal lesion and extranodal lesion 
will be performed according to the revised criteria for response 
assessment in lymphoma [Cheson 2014] (see Appendix D). 
 
The definition of nodal and extranodal lesion is as following: 
 
Nodal lesion:  lymphoma that developed in lymph node and 
lymphoid tissue (amygdala, thymus, spleen, and Peyer's patch 
in small bowel) 
 
Extranodal lesion: lymphoma that developed in non-lymphoid 
organ or tumor mass 
 
Tumor response will be confirmed by independent radiologists at end of 
study prior to final efficacy analysis.  The dates of PR, CR and PD will 
be assessed as applicable. Initial review will be performed by one 
radiologist.  
Tumor assessments will be performed by imaging modalities. CT, MRI, 
magnetic resonance imaging, or PET scanning may be used to evaluate lesions in 
the neck, chest, abdomen, and pelvis; and as a baseline evaluation for patients 
who may have brain metastases.  The PET-CT is encouraged to be performed 
from baseline.  However, when CT is the routine method to monitor patients 
according to hospital standard of care, PET-CT is not required.  Evaluation of 
nodal lesion and extranodal lesion will be performed according to the revised 
criteria for response assessment in lymphoma [Cheson 2014] (see Appendix D 
Section 9.4).  Skin lesions are non-target lesions.  Their response will be 
assessed according to mSWAT, and contribute to overall response determination. 
The definition of nodal and extranodal lesion is as following:

Pre-dose and post dose at 3.5 ± 0.5 hours in triplicates, 5 minutes
between 1st and 2nd, 2nd and 3rd ECGs, on Day 1 of Cycles 1 and 2.
i.
BUN, creatinine, AST, ALT, GGT, total bilirubin (including direct
fraction if total bilirubin abnormal), lipase, amylase, total protein,
albumin, alkaline phosphatase, sodium, potassium, calcium,
magnesium and glucose, LDH, CKMB (creatine kinase MB
fraction).
j.
Urinalysis: dipstick (glucose, protein, occult blood test) followed by
microscopic examination if abnormal results.
l.
Confirmatory test at the Cycle 1 Day 1 (C1D1) visit should be done
before dosing at the local laboratory. Only for women of
childbearing potential, including those who have had a tubal ligation.
Only at EoT visit, Serum and Urine are both acceptable.
m. Complete tumor assessment of all lesions by radiographic or other
modality.  Response and progression for PTCL will be evaluated
according to the revised criteria for response assessment in
lymphoma [Cheson 2014]. Assessment of tumor response will be
scheduled by end of 8 weeks, then every 8 weeks (±1 week) from
C1D1, However, if a patient develops clinical signs and symptoms of
disease progression, or unacceptable toxicity occurs, tumor
assessment may be performed sooner as needed.  If a patient
discontinues study treatment before disease progression (PD) is
recorded, tumor assessments are to be performed approximately
every 3 months ± 2 weeks until PD or the start of new cancer therapy
whichever occurs first, unless consent to study participation is
withdrawn.
g.
Pre-dose and post dose at 3.5 ± 0.5 hours in triplicates, 5 ± 2 minutes

i.
BUN, creatinine, AST, ALT, GGT, total bilirubin (including direct fraction
if total bilirubin abnormal), lipase, amylase, total protein, albumin, alkaline
phosphatase, sodium, potassium, calcium, magnesium and random blood
glucose, LDH, CKMB (creatine kinase MB fraction).
j.
Urinalysis: dipstick (glucose, protein, occult blood test) followedwill be
performed by microscopic examination ifdipstick method, and  in the event
of abnormal dipstick results, additional test may be required.
l.
Only for women of childbearing potential, including those who have had a
tubal ligation.  Confirmatory test at the Cycle 1 Day 1 (C1D1) visit should
be done before dosing at the local laboratory. Only for women of
childbearing potential, including those who have had a tubal ligation. If 
Serum pregnancy test result cannot be obtained on the same day before 
dosing, urine pregnancy test should be conducted additionally and the result 
should be confirmed before dosing.  Only at EoT visit, Serum and Urine are 
both acceptable. 
m. Complete tumor assessment of all lesions by radiographic or other modality.
Baseline bone marrow test (aspiration or biopsy) is required.  Response and
progression for PTCL will be evaluated according to the revised criteria for
response assessment in lymphoma [Cheson 2014]. ], however, PET-CT is
not required but encouraged.  Skin lesions, if present, will be assessed by
mSWAT and contribute to overall tumor response determination by
investigators.  Assessment of tumor response will be scheduled by end of 8
weeksthe 8th  week, then every 8 weeks (± 1 week) from C1D1, However,
if a patient develops clinical signs and symptoms of disease progression, or
unacceptable toxicity occurs, tumor assessment may be performed sooner as
needed.  If a patient discontinues study treatment before disease progression
(PD) is recorded, and if their last tumor assessment was >30 days earlier
from EoT visit, tumor assessment should be performed at EoT.  In these
patients, further  tumor assessments are to be performed approximately
every 3 months ± 2 weeks until PD or the start of new cancer therapy
whichever occurs first, unless consent to study participation is withdrawn.
