Clinical trial NCT03020823
Conditions: Head and Neck Neoplasms
Keywords: SCB01A squamous cell carcinoma of head and neck
Sponsor: SynCore Biotechnology Co., Ltd.
Start date: 2017-04-30; Completion date: 2018-11-20
Enrollment: 10 participants; Allocation: NA; Intervention model: SINGLE_GROUP

Brief summary:
The aim of this study is to evaluate the efficacy and safety of i.v. infusion for 24-hour of SCB01A in subjects with squamous cell carcinoma of head and neck who have failed previous platinum based therapies.

Detailed description:
From pre-clinical pharmacology and phase I clinical study SCB01A has demonstrated promising anticancer action with a vascular disrupting activity that has the potential for treatment of various malignancies, particularly for patients with drug resistance. The drug has been studied in human subjects in a dose escalation phase I study and has shown to be safe for up to 2 cycles of 24 mg/m2 (each cycle consisting of one intravenous \[i.v.\] administration of SCB01A via a central line every 3 weeks). In the phase I study, partial response (PR) (shrinkage of tumor size to 50%) was observed in cycle 9 (3 mg/m2) of one subject with right buccal squamous cell carcinoma and 19/33 (58%) subjects had stable disease (SD) for more than 2 cycles.

Pre clinical study of SCB01A showed that the concentrations at which tubulin inhibition occurred were around 80 nM for 24-hour exposure or 200 nM for 6-hour exposure. However, pharmacokinetic (PK) results of phase I study showed that the average elimination half-life (t1/2) of a 3-hours i.v. infusion of SCB01A is approximately 2.5 hours and almost no SCB01A can be detected after 10 hours, indicating most subjects were treated in short API exposure time and may have been insufficient to achieve efficacy. Therefore, to extend the exposure duration above effective concentration in blood may increase the treatment efficacy.

The aim of this study is to evaluate the efficacy and safety of i.v. infusion for 24-hour of SCB01A in subjects with squamous cell carcinoma of head and neck who have failed previous platinum based therapies.

Arms: arm 1: intra-subject dose escalation starting from 12 mg/m2, then to18 mg/m2, and finally to 24 mg/m2 if no DLT
Interventions: intervention 1: SCB01A
Intervention descriptions: intervention 1: intra-subject dose escalation, 12, 18, 24 mg/m2, 24h-IV infusion (in the vein) on day 1 and 8 of each 21 day cycle. Number of Cycles: until progression or unacceptable toxicity develops.

9.5.2 Appropriateness of Measurements 
The measurements used in this in study were considered appropriate for the indication studied. 
Disease response is a common tool used in cancer trials to study the effectiveness of the study 
drug. Safety and tolerability of the study drug were reported during the trial. 
9.5.3 Primary Efficacy Variable(s) 
The primary efficacy endpoint was the Objective response rate (ORR), defined as complete 
response (CR) + partial response (PR), according to RECIST v1.1 criteria 
9.5.4 Drug Concentration Measurements 
Pharmacokinetic measurement was only performed on subjects enrolled in Stage I. 
 PK blood samples were taken immediately pre-infusion then at 24, 25, 26, 28 and 32 hours 
after start of infusion on Days 1 and 8 of Cycle 3 if dose level of Cycle 3 is 24 mg/m2 
(time window at each sample collected: ±5 min). 
 Blood samples were collected, using 10 mL sodium heparin Vacutainer® tubes. The tube 
was gently inverted to ensure adequate mixing of the blood sample and anticoagulant. 
Samples were placed on ice until separation and must be centrifuged within 20 minutes of 
collection. A precise record of blood sample collection times must be maintained on the 
appropriate source document. 
 Plasma 
samples 
were 
analyzed 
via 
a 
validated 
high 
performance 
liquid 
chromatography/tandem mass spectrometry (HPLC/MS-MS) method for SCB01A. 
9.6 DATA QUALITY ASSURANCE 
The Sponsor or its designee performed the quality assurance and quality control activities of 
this study; however, responsibility for the accuracy, completeness, and reliability of the study 
data presented to the Sponsor lies with the investigator generating the data. 
Audits may be conducted at the discretion of the Sponsor as part of the implementation of 
quality assurance to ensure that the study is being conducted in compliance with the protocol, 
SOPs, GCP, and all applicable regulatory requirements. Audits were independent of and 
separate from the routine monitoring and quality control functions. If such an audit occurred, 
the investigator must agree to allow access to required subject records. By signing this 
protocol, the Investigator granted permission to personnel from the Sponsor, its 
representatives, and appropriate regulatory authorities for on-site monitoring of all appropriate 
study documentation, as well as on-site review of the procedures employed in CRF generation, 
where clinically appropriate. 
9.7 STATISTICAL METHODS PLANNED IN THE PROTOCOL AND 
DETERMINATION OF SAMPLE SIZE 
9.7.1 Statistical and Analytical Plans 
9.7.1.1 Populations for Analysis 
Study subjects were categorized into the following populations for analysis: 
 Intention-to-treat (ITT) population: The ITT population consisted of all subjects enrolled 
in the study and received at least one study treatment.

Squamous Cell Head and Neck Cancer 
Version: 1.0 
Date: 07JAN2019 
 
Page 42 of 129 
 
 Per-protocol (PP) population: The PP population consisted of all subjects who (1) 
withdrew from study for DLT, or (2) completed at least 3 cycles of study treatment 
regimen, have measurable baseline disease and, at least, one post-baseline RECIST 
assessment (PD, SD, PR or CR). Subjects with a major protocol deviation or AE, deemed 
by the Medical Monitor to have an impact on the study endpoints, would be excluded 
from the PP population. 
 PK population: The PK population consisted of all subjects in stage I who received, at 
least, one dose of 24 mg/m2 of SCB01A with sufficient post-dose bio-samples collected 
for PK profile characterization. 
Details of any other populations for analysis were described in the statistical analysis plan 
(SAP). 
9.7.1.2 Statistical Analysis 
Both ITT and PP approaches would be included in the efficacy analyses. The efficacy 
conclusion would be summarized according to analyses of PP population. Safety analysis 
would be done on ITT population. Inferential analysis results would be expressed as point 
estimates and their 95% confidence intervals (CIs). Analyses would be carried out using 
SAS® Software, version 9.4 or higher (SAS Institute, Cary, North Carolina, USA). 
All time-to-event endpoints, including OS and PFS, would be reported in days (median with 
95% CI and range) and calculated using Kaplan-Meier methods. Subjects who have not 
progressed or who have not died at the time of the analysis would be censored at the last 
assessment date. 
9.7.1.3 PK Evaluations 
The blood samples would be assayed for SCB01A and PK parameters (maximum plasma 
concentration [Cmax], clearance [CL], volume of distribution [Vd], half-life [t1/2], elimination 
constant [Kel], mean residence time [MRT] and time to maximum concentration [Tmax]) would 
be determined and presented graphically and descriptively (as appropriate). 
A detailed SAP would be finalized prior to final database lock. Any significant changes to the 
analyses described in this protocol would be addressed in the SAP and the Clinical Study 
Report. 
9.7.2 Determination of Sample Size 
Assumption of sample size calculation: 
 Study design: Simon’s two stage design 
 Type I error rate (one-sided): 5% 
 Power: 80% 
 Response probability of null hypothesis (P0): 0.05 
 Response probability of SCB01A (P1): 0.20 
According to these hypotheses, up to 37 subjects need to be recruited into the study (including 
10 evaluable subjects in the Stage I and 19 evaluable subjects in Stage II, with the additional 8 
subjects to account for replacement of subjects those who withdraw, i.e. dropout rate is 20%). 
At least 4 subjects are required to achieve CR or PR after treatment with SCB01A for the 
study to meet its primary objective. The trial would be discontinued if no objective response 
is observed after the Stage I tumor assessment review.

9.8 CHANGES IN THE CONDUCT OF THE STUDY OR PLANNED ANALYSIS 
The statistical analysis methods have followed study protocol version 1.0, 19DEC2016, 
exceptions and clarifications are described below: 
PK Analysis 
Pharmacokinetic sampling was bio-analyzed, and PK Parameters were calculated by Protech 
Pharmaservices Corporation. All PK and PK parameter data were provided to Sponsor directly, 
no data handling, data listing nor statistical analysis on such data would be done by A2 
Healthcare. 
Objective response rate (ORR) definition  
ORR is defined as the percentage of subjects who have achieved confirmed CR and PR during 
treatment phase, according to RECIST v1.1. Not-confirmed CR or PR, or withdrawn for DLT 
are counted as non-responder. There are 5 subjects who are not evaluated due to clinical 
disease progression or AE/SAE. Tumor non-evaluable subjects are tend to be treatment failure 
and would also be counted as non-responder (not evaluable for response), instead of counted 
as missing.

PROTOCOL SYNOPSIS 
Name of Sponsor/Company:  
SynCore Biotechnology Co. Ltd. 
Name of Study Product:   
SCB01A 
Protocol Number:  
SCB01A-22 
Indication:  
Recurrent or metastatic squamous cell carcinoma of head and neck 
Title of Study:  
An open-label, phase II study to evaluate the efficacy and safety of SCB01A in subjects with 
recurrent or metastatic squamous cell head and neck cancer who have failed platinum-based 
treatment 
Study Center(s):  
Up to 4 centers in Taiwan 
Study Development Phase:   
Phase II 
Planned Number of Subjects:  
Up to 37 subjects will be enrolled, consisting of 10-13 subjects in Stage I and 19-24 subjects in 
Stage II, with replacement for those non-per protocol (non-PP) subjects (estimated 20% dropout 
rate). 
Study Rationale:  
From pre-clinical pharmacology and phase I clinical study SCB01A has demonstrated promising 
anticancer action with a vascular disrupting activity that has the potential for treatment of various 
malignancies, particularly for patients with drug resistance. The drug has been studied in human 
subjects in a dose-escalation phase I study and has shown to be safe for up to 2 cycles of 24 mg/m2 
(each cycle consisting of one intravenous [i.v.] administration of SCB01A via a central line every 
3 weeks). In the phase I study, partial response (PR) (shrinkage of tumor size to 50%) was 
observed in cycle 9 (3 mg/m2) of one subject with right buccal squamous cell carcinoma and 19/33 
(58%) subjects had stable disease (SD) for more than 2 cycles. 
Pre-clinical study of SCB01A showed that the concentrations at which tubulin inhibition occurred 
were around 80 nM for 24-hour exposure or 200 nM for 6-hour exposure. However, 
pharmacokinetic (PK) results of phase I study showed that the average elimination half-life (t1/2) 
of a 3-hours i.v. infusion of SCB01A is approximately 2.5 hours and almost no SCB01A can be 
detected after 10 hours, indicating most subjects were treated in short API exposure time and may 
have been insufficient to achieve efficacy. Therefore, to extend the exposure duration above 
effective concentration in blood may increase the treatment efficacy. 
The aim of this study is to evaluate the efficacy and safety of i.v. infusion for 24-hour of SCB01A 
in subjects with squamous cell carcinoma of head and neck who have failed previous platinum 
based therapies. 
Objectives:  
This is a Phase II study with intra-subject dose escalation to evaluate the efficacy and safety of 
SCB01A in subjects with recurrent or metastatic squamous cell carcinoma in head and neck. 
Primary Objective:  
To assess the objective response rate (ORR) during treatment phase according to the Response

Protocol Number:  
SCB01A-22 
Indication:  
Recurrent or metastatic squamous cell carcinoma of head and neck 
Evaluation Criteria in Solid Tumors (RECIST) version 1.1. 
Secondary Objective: 
 To evaluate the safety and toxicity profile of SCB01A. 
 To assess the overall survival (OS) after first treatment with SCB01A. 
 To assess the progression-free survival (PFS). 
 To assess the best overall tumor response after treatment with SCB01A. 
 To assess the PK profile. 
Trial Design:  
Multicenter, open-label, phase II study of SCB01A administered to subjects with recurrent or 
metastatic squamous cell carcinoma of head and neck.  
Intra-Subject Dose Escalation 
All subjects enrolled in this study will be treated from the same starting dose 12 mg/m
2 (Dose 1) 
given on Days 1 and 8 in a 21-day cycle by 24 h IV infusion. If the subject experiences no dose-
limiting toxicity (DLT) during the period, dose escalation of SCB01A to 18 mg/m2 (Dose 2) 
occurred from Cycle 2; and increased to 24 mg/m2 (Dose 3) on Cycle 3 (Figure 1). 
Figure 1:  
Intra-Subject Dose Escalation 
 
Dose modification 
If the subject experiences a DLT at a given dose level, dose escalation will be halted and a reduced 
dose will be given to the subject. Dose adjustments were allowed based on the toxicity, efficacy 
evaluation, and clinical judgement by physician.  
Rules for dose modifications of the study (Figure 2) are listed as following: 
1. Dose 1 (12 mg/m2), will be the starting dose regimen for all subjects. Safety and clinical 
benefit observation will be performed prior to drug administration on Cycle 2 Day 1. 
a) Dose de-escalation: if any DLT experienced before Cycle 1 Day 8, the dose will be de-
escalated to Dose 1a (9 mg/m
2) for Cycle 1 Day 8. If first DLT during Cycle 1 is 
experienced after Cycle 1 Day 8, the dose will be de-escalated to Dose 1a (9 mg/m
2) for 
Cycle 2. If no DLT is observed in Dose 1a, the subjects will receive the Dose 1a until PD, 
consent withdraw or death. Once more dose de-escalation (Dose 1b, 7 mg/m
2) will be 
allowed if another DLT is observed in Dose 1a. 
b) Dose maintained: If clinical benefit observed at Dose 1 and without DLT, the dose level 
can be maintained until PD, intolerable toxicity, consent withdraw or death.  
2. Dose 2 (18 mg/m2), will be administrated for one cycle and safety and clinical benefit 
observation will be performed prior to drug administration on Cycle 3 Day 1.

Statistical Considerations: 
Populations for Analysis 
Study subjects will be categorized into the following populations for analysis: 
 
Intention-to-treat (ITT) population: The ITT population consists of all subjects enrolled in 
the study and received at least one study treatment. 
 
Per-protocol (PP) population: The PP population will consist of all subjects who (1) 
withdraw from study for DLT, or (2) completed at least 3 cycles of study treatment regimen, 
have measurable baseline disease and, at least, one post-baseline RECIST assessment (PD, 
SD, PR or CR). Subjects with a major protocol deviation or AE, deemed by the Medical 
Monitor to have an impact on the study endpoints, will be excluded from the PP population. 
 
PK population: The PK population will consist of all subjects in stage I who received, at 
least, one dose of 24 mg/m2 of SCB01A with sufficient post-dose bio-samples collected for 
PK profile characterization. 
Details of any other populations for analysis will be described in the statistical analysis plan 
(SAP). 
Statistical Analysis 
Assumption of sample size calculation: 
 
Study design: Simon’s two stage design 
 
Type I error (one-sided): 5% 
 
Power: 80% 


 
 
Protocol No: SCB01A-22 
 
 
Version 1.0; 19-Dec-2016

Page 12 of 69 
Name of Sponsor/Company:  
SynCore Biotechnology Co. Ltd. 
Name of Study Product:   
SCB01A 
Protocol Number:  
SCB01A-22 
Indication:  
Recurrent or metastatic squamous cell carcinoma of head and neck 
 
Response probability of null hypothesis (P0): 0.05 
 
Response probability of SCB01A (P1): 0.20 
According to these hypotheses, up to 37 subjects need to be recruited into the study (including 10 
evaluable subjects in the Stage I and 19 evaluable subjects in Stage II, with the additional 8 
subjects to account for replacement of subjects those who withdraw, i.e. dropout rate is 20%). At 
least 4 subjects are required to achieve CR or PR after treatment with SCB01A for the study to 
meet its primary objective. The trial will be discontinued if no objective response is observed after 
the Stage I tumor assessment review. 
Stopping rule: stopped early for futility if less than 1/10 evaluable subjects showed ORR in Stage 
I; with no further investigation of the drug is less than 4/29 evaluable subjects achieve ORR by the 
end of Stage II. 
Both according to ITT and PP approaches will be included in the efficacy analyses. The efficacy 
conclusion will be summarized according to analyses of PP population. Safety analysis will be 
done on ITT population. Inferential analysis results will be expressed as point estimates and their 
95% confidence intervals (CIs). Analyses will be carried out using SAS® Software, version 9.4 or 
higher (SAS Institute, Cary, North Carolina, USA). 
All time-to-event endpoints, including OS and PFS, will be reported in days (median with 95% CI 
and range) and calculated using Kaplan-Meier methods. Subjects who have not progressed or who 
have not died at the time of the analysis will be censored at the last assessment date. 
PK Evaluations 
The blood samples will be assayed for SCB01A and PK parameters (maximum plasma 
concentration [Cmax], clearance [CL], volume of distribution [Vd], half-life [t1/2], elimination 
constant [Kel], mean residence time [MRT] and time to maximum concentration [Tmax]) will be 
determined and presented graphically and descriptively (as appropriate). 
A detailed SAP will be finalized prior to final database lock. Any significant changes to the 
analyses described in this protocol will be addressed in the SAP and the Clinical Study Report.  
Duration of the Study 
The planned duration of the entire study is approximately 26 months with an enrollment period of 
12 months. 
End of Study 
End of study will be either 12 months after the 1st treatment with SCB01A or end of 27 weeks 
survival follow-up, whichever comes later.

[1] Subjects may continue treatment beyond 3 cycles (9 weeks) of SCB01A treatment per investigator discretion if they are experiencing clinical benefit, until the study is 
terminated. Refer to Table 2 for the schedule of assessments for additional treatment cycles. 
[2] EOT visit should be conducted 14 or 21 days (±2 days) after last infusion, depending on last infusion was given on Day 8 or Day 1, respectively. Early withdrawal visit 
should be conducted after the subject received the last dose of study treatment. A toxicity follow-up (can be done by phone contact) should be performed 28±3 days after 
the last dose of study treatment.

Microscopic exam includes bacteria, cast, crystals, epithelial cells, RBC, and WBC.  
[8] Hematology, clinical chemistry and urinalysis test results within 2 days prior to Cycle 1, Day 1 (C1D1) are acceptable. Only items not performed or obtained within 2 
days prior to C1D1 should be tested. 
[9] PK will only be performed on subjects enrolled in Stage I. PK blood samples will be taken immediately pre-infusion then at 24, 25, 26, 28 and 32 hours after the start of 
infusion on Days 1 and 8 of Cycle 3 if dose level of Cycle 3 is 24mg/m2 (time window at each sample collected: ±5 min). 
[10] Serum pregnancy test for women of childbearing potential must be performed ≤ 14 day prior to first dose. 
[11] i.v. infusion for 24-hour of SCB01A on Days 1 and 8 of each cycle in a 3-week cycle (time window: 24 hours ±10 min). 
[12] To be performed for all subjects at baseline and then during the trial only if grade 2 or above neurological symptoms experienced by the subject after receiving treatment 
with SCB01A.Refer Section 5.9 for further details. 
[13] To be performed when necessary at the subject’s request or per Investigator decision.

Introduction 
1.1. 
Background 
Vascular disrupting agents (VDAs) are designed to disrupt the already abnormal 
vasculature that supports tumors by targeting their already dysmorphic endothelial 
cells. VDAs induce rapid and selective shutdown of the tumor blood supply resulting 
in tumor death while leaving the blood supply in normal tissues relatively intact2,3. 
The largest group of VDAs is the tubulin-binding combretastatins. Combretastatin A4 
phosphate (CA4P) is a small organic molecule found in the bark of the African bush 
willow tree (Combretum caffrum)2. Endothelial cells have been shown to be 
particularly sensitive to the effects of CA4P compared with various other cell types 
and several preclinical studies have demonstrated selective in vitro activity of CA4P 
against proliferating endothelial cells2. 
SCB01A is a novel heterocyclic combretastatin A-4 (CA-4) analogue that binds to the 
colchicines-binding site of the ß-subunit of tubulin thereby inhibiting polymerization 
and effectively preventing mitosis in a manner similar to that seen with other “spindle 
poisons”, e.g., vincristine, vinblastine and vinorelbine, which are in use as cancer 
chemotherapeutic agents. Because SCB01A has VDAs property, SynCore plans to 
develop SCB01A as a treatment for a variety of oncologic indications such as 
non-small cell lung cancer, breast cancer, head and neck cancer, acute lymphoblastic 
leukemia, nephroblastoma and testicular cancer. 
Compounds that interfere with the cell cycle by interfering with normal biology of 
tubulin are prominent anti-cancer agents because they can inhibit the proliferation of 
tumor cell lines derived from various organs. Tubulin-containing structures are 
important for diverse cellular functions, including chromosome segregation during 
cell division, intracellular transport, development, and maintenance of cell shape, cell 
motility, and possibly distribution of molecules on cell membranes. The drugs that 
interact with tubulin are heterogeneous in chemical structure. However, a common 
characteristic of these agents is that while binding to tubulin, they cause its 
precipitation and sequestration to interrupt many important biologic functions that 
depend on the microtubular class of subcellular organelles. One class of 
well-characterized and clinically used antimitotic drugs is those of natural origin, 
including the taxanes (paclitaxel, docetaxel), vinca alkaloids (vincristine, vinblastine, 
vinorelbine), and podophyllotoxins. These agents either inhibit the polymerization of 
tubulin (vinca alkaloids) or prevent the disassembly of microtubules (taxanes). 
SCB01A has been studied extensively since 2005 to evaluate its pharmacokinetic (PK) 
profile, metabolism, in vitro genotoxicity, and acute and sub-acute toxicity. SCB01A 
binds to colchicine binding sites of tubulin much more strongly than colchicines, and 
as with other antimicrotubule inhibitors, it arrests the cells on the G2/M phase in a 
time- and concentration-dependent manner, subsequently leading to cell apoptosis. 
Additional studies indicate that the effect of SCB01A on cell-cycle arrest is associated 
with an increase in cyclin B1 levels and a mobility shift of Cdc2 and Cdc25C. The 
changes in Cdc2 and Cdc25C coincide with the appearance of phosphoepitopes

recognized by a marker of mitosis, MPM-2. Furthermore, phosphorylated forms of 
Bcl-2, perturbed membrane mitochondrial potential, and activation of the caspase 3 
cascade may be involved in SCB01A-induced apoptosis. 
1.2. 
Rationale for the Study 
The research data available to date indicate that SCB01A is a promising anti-cancer 
agent with vascular disrupting activity that has potential for treatment of various 
malignancies, particularly for patients with drug resistance to existing therapies. The 
drug has been trialed in human subjects in dose-escalation phase I study, and 
maximum tolerated dose (MTD) is 24 mg/m2 (each cycle consists of one intravenous 
[i.v.] administration of SCB01A via a central line every 3 weeks). In the phase I study, 
partial response (PR) (shrinkage of tumor size to 50%) was observed in cycle 9 
(3 mg/m2) of one subject with right buccal squamous cell carcinoma and disease 
stabilization lasted for 14 cycles. Summary from current clinical findings note a total 
of 19/33 (57.6%) subjects had stable disease (SD) for at least 2 cycles. Extended 
disease stabilizations were especially observed for 23 cycles in one subject with 
cholangiocarcinoma (4 mg/m2) and 15 cycles in one subject with rectal cancer 
(3 mg/m2) respectively, suggested that the most prominent SD subjects remain in low 
dose (less than 6.5 mg/m2). 
Pre-clinical study of SCB01A showed that the concentrations at which tubulin 
inhibition occurred were around 80 nM for 24-hour exposure or 200 nM for 6-hour 
exposure. However, pharmacokinetic (PK) results of both phase I study and an 
ongoing phase II study showed that the average elimination half-life (t1/2) of a 3-
hours i.v. infusion of SCB01A is approximately 2.5 hours and almost no SCB01A can 
be detected after 10 hours, indicating most subjects were treated in short API 
exposure time and may have been insufficient to achieve efficacy. Furthermore, 
clinical experiences demonstrated that extended infusion duration may reduce 
susceptible chemotherapy induced adverse reaction especially peripheral neuropathy 
(JCO 1999, 17(11): 3403-11). Summary from both efficacy and safety evidences 
suggesting that to extend the cumulative exposure duration of SCB01A beyond 
effective concentration in blood may be benefit to patient’s best interest. 
Two phase I clinical studies were performed “A Phase 1 Dose Escalation Study of 
SCB01A in Subjects with Advanced Solid Tumors Who Have Failed Standard 
Therapy” and “Long-Term Compassionate Use Study for Continued Administration 
of SCB01A in Subjects Who Completed Treatment With SCB01A in the Previous 
Protocol #SCB01A-01” respectively. The phase I study demonstrated that SCB01A 
has encouraging safety and efficacy and support for further Phase II study. 33 subjects 
were enrolled in the study and 31 subjects completed the main treatment. Among the 
31 subjects, 11 of them completed the extension treatment of SCB01A. Up to date, 5 
subjects, two in main and extension period respectively, experienced 7 SUSAR events. 
(Including gastric ulcer bleeding, thrombocytopenia, cough, radiation recall dermatitis, 
thromboembolic event, muscle weakness lower limb, and sepsis). In addition, 5 dose 
limiting toxicities and 61 adverse reactions were reported in this study.

Investigational Plan 
3.1. Description of Overall Study Design and Plan 
This study is a multicenter, open-label, Phase II trial. The study will be conducted in 
two stages: 
 Stage I: A total of up to 10 evaluable subjects will be enrolled for Stage I to 
receive at least 3 cycles of i.v. administration by 24-hours infusion of SCB01A 
under intra-subject dose escalation regimen. The tumor response review will be 
performed with the subjects who completed at least 3 cycles of SCB01A treatment. 
If at least one response (CR or PR) is observed, another 19 evaluable subjects will 
be enrolled into Stage II. 
 Stage II: 19 evaluable subjects will be enrolled at stage II and treated with the 
same intra-subject dose escalation regimen from starting dose 12 mg/m
2. The 
tumor response review will be performed with the subjects who completed 3 
cycles of SCB01A treatment.  
Intra-Subject Dose Escalation 
All subjects enrolled in this study will be treated from the same starting dose 12 
mg/m2 (Dose 1) given on Days 1 and 8 in a 21-day cycle by 24 h IV infusion. If the 
subject experiences no dose-limiting toxicity (DLT) during the period, dose escalation 
of SCB01A to 18 mg/m2 (Dose 2) occurred from cycle 2; and increased to 24 mg/m
2 
(Dose 3) on cycle 3 (Figure 1).  
Figure 1:  
Intra-Subject Dose Escalation Plan 
 
Dose Modification 
If the subject experiences a DLT at a given dose level, dose escalation will be halted 
and a reduced dose will be given to the subject. Dose adjustments were allowed based 
on the toxicity, efficacy evaluation, and clinical judgment by physician.  
Rules for dose modifications of the study (Figure 2) are listed as following: 
1. Dose 1 (12 mg/m2), will be the starting dose regimen for all subjects. Safety and 
clinical benefit observation will be performed prior to drug administration on 
Cycle 2 Day 1. 
a) Dose de-escalation: if any DLT experienced before Cycle 1 Day 8, the dose 
will be de-escalated to Dose 1a (9 mg/m2) for Cycle 1 Day 8. If first DLT 
during Cycle 1 is experienced after Cycle 1 Day 8, the dose will be de-
escalated to Dose 1a (9 mg/m2) for Cycle 2. If no DLT is observed in Dose 1a, 
the subjects will receive the Dose 1a until PD, consent withdraw or death.

Page 30 of 69 
Once more dose de-escalation (Dose 1b, 7 mg/m2) will be allowed if another 
DLT is observed in Dose 1a. 
b) Dose maintained: If clinical benefit observed at Dose 1 and without DLT, the 
dose level can be maintained until PD, intolerable toxicity, consent withdraw 
or death. 
2. Dose 2 (18 mg/m2), will be administrated for one cycle and safety and clinical 
benefit observation will be performed prior to drug administration on Cycle 3 Day 
1.  
a) Dose de-escalation: if any DLT experienced before Cycle 2 Day 8, the dose 
will be de-escalated to Dose 2a (15 mg/m2) for Cycle 2 Day 8. If first DLT 
during Cycle 2 is experienced after Cycle 2 Day 8, the dose will be de-
escalated to Dose 2a (15 mg/m2) for Cycle 3. If no DLT is observed in Dose 
2a, the subjects will receive the Dose 2a until PD, consent withdraw or death. 
Once more dose de-escalation (Dose 2b, 12 mg/m2) will be allowed if another 
DLT is observed in Dose 2a. 
b) Dose maintained: If clinical benefit observed at Dose 2 and without DLT, the 
Dose 2 can be continued until PD, intolerable toxicity, consent withdraw or 
death. 
3. Dose 3 (24 mg/m2), will be administrated for one cycle and safety and tumor 
assessment will be performed prior to drug administration on Cycle 4 Day 1.  
a) Dose de-escalation: if any DLT experienced before Cycle 3 Day 8, the dose 
will be de-escalated to Dose 3a (20 mg/m2) for Cycle 3 Day 8. If first DLT 
during Cycle 3 is experienced after Cycle 3 Day 8, the dose will be de-
escalated to Dose 3a (20 mg/m2) for Cycle 3. If no DLT is observed in Dose 
3a, the subjects will receive the Dose 3a until PD, consent withdraw or death. 
Once more dose de-escalation (Dose 3b, 16 mg/m2) will be allowed if another 
DLT is observed in Dose 3a.

Dose Modification 
 
If the subject experienced any neurotoxic DLT, the subject will be withdrawn. 
Subjects will be considered to be non-evaluable for ORR if they receive study drug 
for fewer than 9 weeks (3 cycles) of treatment for any reason other than study-drug 
related toxicity. Non-evaluable subjects will be replaced. 
All subjects will be treated until the occurrence of progressive disease, intolerable 
adverse events (AEs)/toxicity, consent withdrawal or death. After discontinuation of 
study treatment, all subjects will be followed for survival and disease-specific 
therapies of the clinician’s choice will be administered. Follow-up visits will be 
scheduled every 3 weeks for 9 weeks (i.e. week 3, week 6, and week 9), thereafter 
every 9 weeks until the end of the study. 
End of study will be either 12 months after the 1st treatment with SCB01A or end of 
27 weeks survival follow-up, whichever comes later. 
Data and Safety Monitoring Board (DSMB) 
The responsibilities of the DSMB, composed of medical monitors (physicians 
experienced in oncology studies) and at least one statistician, are to review and 
evaluate the data for safety, study conduct and progress, and make recommendations 
concerning the continuation, modification, or termination of study. Serial assessments 
of PK results also may be taken into account for safety evaluation. A neurologist will 
be invited to join DSMB meeting as a consultant when neurotoxicity occurred. 
The document review or meeting of DSMB will be held when the following scenarios: 
 A subject is not recovered from Grade 2 neurotoxicity over three weeks; 
 A subject revealed Grade 3 or above neurotoxicity; 
 After 10 evaluable subjects finished the study in Stage I;

Treatments 
4.1. 
Identity of Investigational Product (IP) 
SCB01A (a novel heterocyclic CA-4 analogue) is dissolved in absolute EtOH, PEG 
300, and Solutol®. Solutol® (Macrogol 15 Hydroxystearate) is a non-ionic solubilizer 
for injection solutions and conforms to the requirements of the European 
Pharmacopoeia monograph. PEG 300 (Macrogol 300) is a mixture of polymers of 
ethylene oxide and water and their ethers. The average molecular weight is about 300 
and conforms to the requirements of the European Pharmacopoeia monograph. 
Dehydrated alcohol contains > 99.2% by weight, corresponding to > 99.5% by 
volume at 15.56oC of C2H5OH and conforms to the requirements of the US 
Pharmacopoeia monograph. 
SCB01A is a water insoluble, white to slightly yellow solid. At room temperature, the 
water solubility of SCB01A is 0.9 μg/ml. Formulated SCB01A is a sterile, clean, 
colorless to slightly yellow viscous solution. 
4.2. 
Study Drug Packaging and Labeling 
The study drug is packaged in glass vials with a rubber stopper and flip-off seal 
labeled with the study protocol number, contents, directions for use, storage directions, 
clinical trial statement, and sponsor name. 
4.3. 
Study Drug Storage Conditions 
Formulated SCB01A can be stored at temperatures 15-25 oC. Although direct data on 
its photosensitivity is unavailable, the avoidance of light is recommended. 
4.4. 
Study Drug Dose Preparation and Administration 
The study drug, SCB01A is packaged as 10 mg/ml in 5 ml/vial. The injection volume 
of SCB01A should be calculated based on the BSA of the subject. (See Section 5.3). 
The study drug will be diluted in normal saline solution before infusion. An equal 
volume of normal saline will be drawn out from a 250 ml normal saline container 
before adding the SCB01A injection solution. The total volume of study drug diluted 
solution will be equal to 250 ml. The study drug should be administered for 24 hours 
(time window 24 hours±10 mins) by i.v. infusion through a central line in order to 
avoid potential extravasation and tissue necrosis. The duration from drug dilution to 
completion of 24h i.v. infusion must not exceed a maximum of 28 hours. For further 
details, please refer to the IMP Manual. 
4.5.

Clinical Research Organization (CRO). Disposition of all unused study drug will be 
carried out according to instructions provided by the sponsor or CRO at the end of the 
study and after a final drug accountability assessment is performed by the monitor. 
4.6. 
Method of Assigning Subjects to Treatment Groups 
There is no randomization in this study. All subjects will receive the study drug, and 
the dose as per intra-subject dose escalation plan. Subjects will be assigned to Dose 1 
(12 mg/m2) initially on Days 1 and 8 of Cycle 1. If the subject experiences no DLT 
during this period, dose escalation of SCB01A to Dose level 2 (18 mg/m2) occurred 
from Cycle 2; and increased to Dose level 3 (24 mg/m2) on Cycle 3. 
4.7. 
Selection of Doses in the Study 
Doses were selected based on pre-clinical data and data obtained from Phase I and 
ongoing Phase II studies as described in Section 1.2. 
4.8. 
Selection and Timing of Dose for each Subject 
The selection and timing of dose for each subject is described in Section 3.1.  
Subjects entered into Stage I and II will be allocated Dose 1, 2 and 3 under intra-
subject dose escalation regimen. If the subject experiences a DLT at a given dose 
level, dose escalation will be halted and a reduced dose will be given to the subject. 
Dose adjustments were allowed based on the toxicity, efficacy evaluation, and clinical 
judgment by physician. 
Dose 1: 
One i.v. administration of 12 mg/m2 SCB01A on Days 1 and 8 of a

terminology for the disease/disorder/condition, the date of diagnosis, and the 
history status (resolved or ongoing) will be documented. Surgery and procedure: 
within 1 year prior to screening visit should be recorded, cancer history should be 
recorded on life time base. 
5.2. 
Physical Examination 
A complete physical examination will be performed at baseline and each clinic visit 
prior to drug administration, if applicable and the EOT/Early Withdrawal visit to 
include a review of all systems. Each body system will be classified as being either 
normal or abnormal, with abnormalities for each body system noted. Subsequent 
physical examinations will identify changes from the baseline examination with both 
positive and negative changes being noted. The physical examination will include 
routine examinations for the following: 
 
Abnormalities of the extremities 
 
Heart/cardiovascular abnormalities 
 
Musculoskeletal abnormalities 
 
Dermatologic abnormalities 
 
Neurologic abnormalities 
Any other body system, for which an abnormality is noted and which, in the opinion 
of the Investigator, is relevant to the safety of the participant or could impact safety or 
efficacy results for the study subject; i.e., the abnormality is clinically significant. 
5.3. 
BSA Calculation 
BSA will be calculated on dosing days, using the formula below4:

The total dose (mg) will be calculated as:  
Total Dose (mg) = Dose Level (mg/m2) x BSA (m2) 
5.4. 
Vital Signs 
Vital signs will be obtained at screening/baseline, at all clinic visits during treatment 
phase and at the EOT/Early Withdrawal visit. 
Note: On days of study treatment administration (Day 1 and 8), the Vitals will be 
taken two times (pre- and post-treatment). Post-Treatment Vital Signs will be assessed 
at the end of 24-hour study treatment infusion. 
Vital signs will include height, weight, heart rate, blood pressure, respiratory rate, and 
body temperature. Respiratory rate, heart rate, and blood pressure (systolic/diastolic) 
will be obtained after the subject has been at rest for at least 5 minutes in a sitting 
position. Height (cm) measurement will only be performed at baseline and weight (kg) 
measurement will be performed at each visit before a study treatment infusion. 
If vital sign measurements coincide with a blood sample, the vital signs will be taken 
prior to obtaining the blood sample. 
Body temperature will be taken and recorded in degrees Centigrade.

regarding subsequent treatment continuation or modification) unless the symptom is 
deemed as clinical significant. 
5.10. Appropriateness of Measurements 
The measurements used in this in study are considered appropriate for the indication 
studied. Disease response is a common tool used in cancer trials to study the 
effectiveness of the study drug. Safety and tolerability of the study drug will be 
reported during the trial.

Safety and Efficacy Variables 
6.1. 
Efficacy Measurements 
Tumor response will be assessed by using computerized tomography (CT) or MRI 
scans according to RECIST v1.1 at baseline and at the end of Cycle 3 (at C3D21/EOT 
visit). For subjects who are continuing treatment beyond 3 cycles (9 weeks), tumor 
assessment will be performed at every three cycles until progression of disease (i.e. at 
or prior to Day 1 of Cycles 4, 7, 10 and so on). Any additional assessments can be 
arranged when clinically indicated. 
Scans must include brain, chest, abdomen, and pelvis. The imaging technique used at 
baseline should be used throughout the study. 
Subjects will be considered evaluable for tumor assessment in this study if they fulfill 
the criteria for evaluation according to RECIST v1.1, i.e., those subjects who undergo 
a baseline disease assessment within 4 weeks of treatment initiation, and who undergo 
at least 1 disease assessment on study (the following should be revised if revision in 
corresponding part in synopsis is accepted) . 
 ORR is defined as the percentage of subjects who have achieved confirmed CR 
and PR at a particular time point after first treatment, according to RECIST v1.1. 
 PFS is defined as the time from the start of treatment up to the date of first 
progression based on RECIST v1.1 or the date of death, whichever comes first.  
 OS is defined as the as the time from the start of treatment up to the time that the 
subject is still alive. 
 Best overall tumor response defined as an objective response or stable disease of 
treatment phase. 
Survival data will be collected throughout the active treatment phase and during the 
follow-up period. Survival follow-up after subject discontinuation of treatment will be 
conducted every 3 weeks during the first 9 weeks, thereafter every 9 weeks until the 
end of the study.  
6.2. 
Dose Limiting Toxicity (DLT) 
All toxicities will be classified according to the NCI Common Terminology Criteria 
for AEs (CTCAE) version 4.03. 
DLT will be defined as the occurrence of any of the following criteria unless there is 
definitive alternative evidence that administration of SCB01A did not cause the 
specific toxicity: 
 
Grade 4 neutropenia exceeding 5 days’ duration 
 
Grade 4 thrombocytopenia 
 
Grade 4 anemia 
 
Grade 3 or greater neutropenia with complications (e.g., fever, infection etc.)

 
Grade 3 or greater thrombocytopenia with complications (e.g., bleeding) 
 
Grade 3 or greater non-hematological AEs including Grade 3 unmanageable 
nausea and vomiting that persist for 3 or more days after drug administration. 
Grade 3 fatigue lasting for ≤1 week is not considered as a DLT 
 
Grade 3 or greater prolonged QTc interval 
 
Grade 3 or greater neurotoxicity 
 
Delayed treatment exceeding 14 days duration due to drug-related toxicity. 
 
Not able to recover from grade 2 neurotoxicity exceeding 3 weeks 
6.3. 
Safety Measurements 
The following safety assessments will be done during the study: 
 
Incidence and intensity of AEs evaluated using the CTCAE version 4.03 
 
Incidence and intensity of clinically significant abnormal laboratory values 
evaluated using the CTCAE version 4.03 
 Percentage of subjects experiencing dose adjustments, including delays or 
omissions or discontinuation of study medication 
 
Physical examination findings 
 
Vital signs measurements 
 
ECG (including PR, QRS, QTc intervals) findings  
 
Nerve conduction velocity examination (baseline for all subjects; symptom 
occurring and end of the study for subjects with grade 2 or greater neurological 
symptom) 
6.4. 
Pharmacokinetic Measurements 
PK will only be performed on subjects enrolled in Stage I. 
 PK blood samples will be taken immediately pre-infusion then at 24, 25, 26, 28 
and 32 hours after start of infusion on Days 1 and 8 of Cycle 3 if dose level of 
Cycle 3 is 24 mg/m2 (time window at each sample collected: ±5 min). 
 Blood samples will be collected, using 10 mL sodium heparin Vacutainer® tubes. 
The tube will be gently inverted to ensure adequate mixing of the blood sample 
and anticoagulant. Samples will be placed on ice until separation and must be 
centrifuged within 20 minutes of collection. A precise record of blood sample 
collection times must be maintained on the appropriate source document. 
 Plasma samples will be analyzed via a validated high performance liquid 
chromatography/tandem mass spectrometry (HPLC/MS-MS) method for SCB01A.

Adverse Events Definitions and Reporting 
7.1. 
Adverse Events  
An AE is any untoward medical occurrence that occurs in a patient or clinical 
investigation subject administered a pharmaceutical product, and which does not 
necessarily have to have a causal relationship with this treatment. An AE can 
therefore be any unfavorable and unintended sign (including abnormal laboratory 
finding), symptom, or disease temporally associated with the use of an IP, whether or 
not considered related to the medicinal product (definition per ICH E2A and E6 R1). 
All AEs, regardless of seriousness, severity, or presumed relationship to study therapy, 
must be recorded using medical terminology on the AE CRF page. Whenever possible, 
diagnoses should be given when signs and symptoms are due to a common etiology 
(e.g., cough, runny nose, sneezing, sore throat, and head congestion should be 
reported as “upper respiratory infection”). All measures required for AE management 
must be recorded in the source document and reported according to Sponsor 
instructions. 
For all AEs, the Investigator must pursue and obtain information adequate to both 
determine the outcome of the AE and to assess whether it meets the criteria for 
classification as an SAE (see Section on SAEs) requiring immediate notification to 
the Sponsor or its designated representative. For all AEs, sufficient information 
should be obtained by the Investigator to determine the causality of the AE. 
Interventions for pre-treatment conditions (e.g., elective cosmetic surgery) or medical 
procedures that were planned before study enrolment are not considered AE. 
 
7.1.1. Intensity Assessment 
The severity of the AE will be graded according to the NCI Common Terminology 
Criteria for AEs (CTCAE) Grading Scale Version 4.03 (Publish Date: May 28, 2009, 
http://ctep.cancer.gov/reporting/ctc.html). 
The maximum severity (intensity) of the AE will be categorized by the Investigator as 
follows: 
Grade 1 
Mild; asymptomatic or mild symptoms; clinical or diagnostic 
observations only; intervention not indicated 
Grade 2 
Moderate; minimal, local or non-invasive intervention indicated; 
limiting age-appropriate instrumental activities of daily living 
Grade 3 
Severe or medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; 
limiting self-care activities of daily living. 
Grade 4 
Life-threatening consequences; urgent intervention indicated 
Grade 5 
Death related to AE 


 
 
Protocol No: SCB01A-22 
 
 
Version 1.0; 19-Dec-2016 
 
 
Confidential 
 
Page 50 of 69 
For AEs not covered by NCI CTCAE, the severity will be characterized as “mild,” 
“moderate,” or “severe” according to the following definitions: 
 Mild events are usually transient and do not interfere with the subject’s daily 
activities 
 Moderate events introduce a low level of inconvenience or concern to the subject 
and may interfere with daily activities 
 Severe events interrupt the subject’s usual daily activities. 
When changes in the intensity of an AE occur more frequently than once a day, the 
maximum intensity for the experience should be noted. If the intensity category 
changes over a number of days, then those changes should be recorded separately 
(with distinct onset dates). All AEs, due to any cause that occurs during the 
investigation, whether or not related to the study drug, should be reported to the 
Safety Coordinator. 
 
7.1.2. Causality Assessment 
The investigator will assign a relationship to the study drug (i.e. causality) for all AEs 
that occur during the study using the definitions below: 
 
 Unrelated: The AE is clearly related to other causes such as participant’s clinical 
state, environmental factors, or other therapies administered. 
 Unlikely to be related: The AE does not follow a reasonable temporal sequence 
from study drug administration; could readily have been produced by other causes 
such as the participant’s clinical state, environmental factors, or other therapies 
administered; does not follow a known response pattern to the study drug.  
 Possibly related: The AE follows a reasonable temporal sequence from study 
drug administration; follows a known response pattern to the study drug; could 
readily have been produced by other causes such as the participant’s clinical state, 
environmental factors, or other therapies administered.  
 Probably related: The AE follows a reasonable temporal sequence from study 
drug administration; follows a known response pattern to the study drug; cannot 
be reasonably explained by other factors such as the participant’s clinical state, 
environmental factors, or other therapies administered; improvement upon 
cessation of test drug.  
 Definitely related: The AE follows a reasonable temporal sequence from study 
drug administration; follows a known response pattern to the study drug; cannot 
be reasonably explained by other factors such as the participant’s clinical state, 
environmental factors, or other therapies administered; improvement upon 
cessation of test drug or reappears upon repeat exposure (if rechallenge occurs).

7.2. 
Adverse Event Reporting 
All AEs occurring during the study (from the time of the first study treatment until 
28 days after the last dose of study treatment) observed by the Investigator or reported 
by the subject (whether or not attributed to study drug), will be reported on the CRF. 
Clinically significant AEs considered related or non-related to the IP by the 
Investigator or the Sponsor will be followed until resolved or considered stable by the 
Investigator. The following information must be provided: description; dates of onset 
and resolution; severity; assessment of relatedness to IP, other suspect drug, or device; 
and action taken. The investigator may be asked to provide follow-up information. 
All AEs, serious or not, that result in the subject’s permanent withdrawal of IP or 
from the study will be discussed between the investigator and medical monitor. The 
CRF for EOT/Early Withdrawal Visit should be completed including reason of 
withdrawal. 
It will be the investigator’s clinical judgment whether or not an AE is of sufficient 
severity to require the subject’s removal from study treatment. A subject may also 
voluntarily withdraw from study treatment due to what he or she perceives as an 
intolerable AE. If either of these occurs, the subject must undergo EOT assessment 
and be given appropriate care under medical supervision until symptoms cease or the 
condition becomes stable. 
7.3. 
Serious Adverse Events (SAEs) 
An SAE is defined as any untoward medical occurrence that at any dose (ICH E2A and 
E6 R1):  
 Results in death.  
 Is life-threatening.  
This means that the subject is at risk of death at the time of the event; it does not 
mean that the event hypothetically might have caused death if it were more severe.  
 Requires inpatient hospitalization or prolongation of existing hospitalization.  
 Results in persistent or significant disability or incapacity.  
 Is a congenital anomaly or birth defect.  
Other important medical events that may not be immediately life-threatening or result 
in death or hospitalization, based upon appropriate medical judgment, are considered 
SAEs if they are thought to jeopardize the subject and/or require medical or surgical 
intervention to prevent one of the outcomes defining a SAE. 
Since SAEs are critically important for the identification of significant safety 
problems, it is important to take into account both the Investigator’s and the sponsor’s 
assessment. If either the sponsor or investigator believes that the event is serious, the 
event must be considered serious and evaluated by the Sponsor for expedited 
reporting. 


 
 
Protocol No: SCB01A-22 
 
 
Version 1.0; 19-Dec-2016 
 
 
Confidential 
 
Page 52 of 69 
All SAEs must be reported to the sponsor or sponsor designee immediately after the 
Investigator becomes aware of the event, along with a determination as to whether it 
is associated with the IP or any other study procedure. 
Disease progression should not be recorded as an AE or SAE term; instead, signs and 
symptoms of clinical sequelae resulting from disease progression will be reported if 
they fulfill the SAE definition.  
7.4. 
Serious Adverse Event Reporting 
All SAEs, irrespective of relationship to IP, must be reported within 24 hours of the 
Investigator knowledge of the event to the Sponsor or CRO. In particular, if the SAE 
is fatal or life-threatening, notification to the Sponsor must be made immediately, 
irrespective of the extent of available AE information. This timeframe also applies to 
follow-up information on previously forwarded SAE reports as well as to the initial 
and follow-up reporting of exposure during pregnancy and exposure via breast 
feeding cases. 
Relevant medical records should be provided to the Sponsor or CRO as soon as they 
become available; autopsy reports should be provided for deaths if available. Should 
an Investigator be made aware of an SAE occurring any time after the reporting 
period, it must be promptly reported.  
All SAEs that have not resolved by the end of the study, or that have not resolved 
upon discontinuation of the subject's participation in the study, must be followed until 
any of the following occurs:  
 The event resolves.  
 The event stabilizes.  
 The event returns to baseline, if a baseline value/status is available.  
 The event can be attributed to agents other than the IP or to factors unrelated to 
study conduct.  
 It becomes unlikely that any additional information can be obtained (subject or 
health care practitioner refusal to provide additional information, lost to follow-up 
after demonstration of due diligence with follow-up efforts).  
7.5. 
Pregnancies 
All initial reports of pregnancy must be reported to the Sponsor within 24 hours of the 
Investigator knowledge of the event using the appropriate pregnancy form.  
For IP, an exposure during pregnancy occurs if:  
 A female becomes, or is found to be, pregnant either while receiving or having 
been directly exposed (e.g., environmental exposure) to the IP, or the female 
becomes, or is found to be, pregnant after discontinuing and/or being directly 
exposed to the IP (maternal exposure) for 28 days after last dose of or exposure to 
IP.  


 
 
Protocol No: SCB01A-22 
 
 
Version 1.0; 19-Dec-2016 
 
 
Confidential 
 
Page 53 of 69 
 A male partner of a pregnant female has been exposed to the IP, either due to 
treatment or environmental exposure, within 3 months prior to the time of 
conception and/or is exposed during his partner’s pregnancy (paternal exposure).  
If any study subject or study subject’s partner becomes or is found to be pregnant 
during the study subject’s treatment with the IP or exposure as defined above, the 
Investigator must submit this information on a Pregnancy form to the Sponsor (or its 
designated representative). In addition, the Investigator must submit information 
regarding environmental exposure to an IP in a pregnant woman (e.g., a subject 
reports that she is pregnant and has been exposed to a cytotoxic product by inhalation 
or spillage) using the Pregnancy form. This must be done irrespective of whether an 
AE has occurred and within 24 hours of awareness of the pregnancy. The information 
submitted should include the anticipated date of delivery (see following information 
related to induced termination of pregnancy). 
Follow-up is conducted to obtain pregnancy outcome information on all exposure 
during pregnancy reports with an unknown outcome. The Investigator will follow the 
pregnancy until completion or until pregnancy termination (e.g., induced abortion) 
and then notify the Sponsor or its designated representative of the outcome as a 
follow-up to the initial Pregnancy form. In the case of a live birth, the structural 
integrity of the neonate can be assessed at the time of birth. In the event of a 
termination, the reason(s) for termination should be specified and, if clinically 
possible, the structural integrity of the terminated fetus should be assessed by gross 
visual inspection (unless pre-procedure test findings are conclusive for a congenital 
anomaly and the findings are reported).  
If the outcome of the pregnancy meets the criteria for immediate classification as an 
SAE (e.g., ectopic pregnancy, spontaneous abortion, intrauterine fetal demise, 
neonatal death, or congenital anomaly [including that in a live born, a terminated fetus, 
an intrauterine fetal demise, or a neonatal death]), the Investigator should follow the 
procedures for reporting SAEs.  
Additional information about pregnancy outcomes that are classified as SAEs follows:  
 “Spontaneous abortion” includes miscarriage and abortion.  
 All neonatal deaths that occur within 1 month of birth should be reported, without 
regard to causality, as SAEs. In addition, infant deaths after 1 month should be 
reported as SAEs when the Investigator assesses the neonatal death as related to 
exposure to IP.  
Additional information regarding the exposure during pregnancy may be requested by 
the Investigator. Follow-up information regarding the outcome of the pregnancy and 
any postnatal sequelae in the infant will be required.

Statistical Methods and Determination of Sample Size 
8.1. 
Statistical and Analytical Plans 
A brief description is given of the planned analysis methodology. Detailed 
descriptions of the statistical analysis methods and data conventions will be provided 
as a separate document; i.e., the Statistical Analysis Plan (SAP). The SAP may also 
include additional exploratory analyses not explicitly mentioned in the following 
sections. A detailed SAP will be finalized prior to final data base lock. Any significant 
changes to the analyses described in this protocol will be addressed in the SAP and 
the Clinical Study Report. 
8.2. 
Determination of Sample Size 
Assumption of sample size calculation: 
 Study design: Simon’s optimal two stage design1 
 Type I error (one-sided): 5% 
 Power: 80% 
 Response probability of null hypothesis (P0): 0.05 
 Response probability of SCB01A (P1): 0.20 
According to these hypotheses, up to 37 subjects need to be recruited into the study 
(including 10 evaluable subjects in the Stage I and 19 evaluable subjects in Stage II, 
with the additional 8 subjects to account for replacement of subjects those who 
withdraw, i.e. dropout rate is 20%). At least 4 subjects are required to achieve CR or 
PR after treatment with SCB01A for the study to meet its primary objective. The trial 
will be discontinued if no objective response is observed after the Stage I tumor 
assessment review. 
Stopping rule: The study will be stopped early for futility if less than 1/10 evaluable 
subjects showed ORR in Stage I; with no further investigation of the drug is less than 
4/29 evaluable subjects achieve ORR by the end of Stage II. 
8.3. 
Populations for Analysis 
Subjects will be categorized into the following populations for analysis: 
ITT population: The ITT population consists of all subjects enrolled in the study and 
received at least one study treatment. 
Per-protocol (PP) population: The PP population will consist of all subjects who 
completed at least 3 cycles of study treatment regimen, have measurable baseline 
disease and at least one post-baseline RECIST assessment (PD, SD, PR or CR). 
Subjects with a major protocol violation, or AE, deemed by the Medical Monitor to 
have an impact on the study endpoints will be excluded from the PP population. 
PK population: The PK population will consist of all subjects in stage I who received, 
at least, one dose of 24 mg/m2 of SCB01A with sufficient post-dose bio-samples 
collected for PK profile characterization.

Safety Analysis 
Safety profile will be evaluated by the following endpoints. 
 
Incidence and intensity of AEs evaluated using the CTCAE version 4.03 
 
Incidence and intensity of clinically significant abnormal laboratory values 
evaluated using the CTCAE version 4.03 
 Percentage of subjects experiencing dose adjustments, including delays or 
omissions or discontinuation of study medication 
 
Physical examination findings 
 
Vital signs measurements 
 
ECG (including PR, QRS, QTc intervals) findings  
 
Nerve conduction velocity examination (baseline for all subjects; symptom 
occurring and end of study for subjects with grade 2 or greater neurological 
symptom) 
All safety endpoint data will be listed and summarized for each dose and day within 
cycle using descriptive statistics. The change from baseline data for the safety 
endpoints will also be summarized using descriptive statistics. 
Number and percentage of subjects experiencing at least one DLT or AE will be 
tabulated by dose. Further details regarding any DLTs or AEs experienced will be 
provided in data listings. All recorded AEs will be listed and tabulated by system 
organ class and preferred term using the Medical Dictionary for Regulatory Activities 
(MedDRA) and by dose level. The incidence of Treatment Emergent AEs (TEAEs) 
during the study period will be tabulated by dose group, body system, and preferred 
term. TEAEs are those events that occur or worsen on or after first dose of IP and up 
to 28 days after the last dose. TEAEs are AEs with onset dates on or after the first 
dosing date. Those with missing onset dates will be included as treatment emergent. 
Number and percentage of subjects who withdrew/stopped dosing will be tabulated. 
Number and percentage of subjects who missed 1 or more doses (1 dose, 2 doses, etc.) 
in any cycle will be tabulated by cycle. 
Serious AEs, Grade 3 and above AEs, AEs related to study treatment, and AEs 
causing discontinuation will be tabulated. AEs for individual subjects will be listed, 
along with information regarding onset, duration, severity, and relationship to study 
treatment. 
Vital signs, physical examination, ECG, and clinical laboratory test results will be 
listed and summarized by dose group, cycle and day within cycle as applicable and 
may be presented graphically. Any significant or outside normal range limits value for 
vital signs, physical examination, ECG, or clinical laboratory results will be listed.

 Insurance certificate 
9.8. 
Data Handling and Record Retention 
9.8.1. Source Documents 
Source documents are considered to be all information in original records and 
certified copies of original records of clinical findings, observations, data, or other 
activities in a clinical study necessary for the reconstruction and evaluation of the 
study. 
9.8.2. Recording and Collection of Data 
All source documents and CRFs will be completed as soon as possible after the 
subject’s visit. Corrections to data on the source will be documented. The investigator 
will review CRFs to indicate that, to his/her knowledge, they are complete and 
accurate. Designated source documents will be signed and dated by the appropriate 
study personnel. The investigator must agree to complete and maintain source 
documents and CRFs for each subject participating in the study. 
9.8.3. Clinical Data Management 
The sponsor and/or designated CRO will be responsible for the processing and quality 
control of the data. Data management will be carried out as described in the sponsor’s 
or CRO’s SOPs for clinical studies. 
The handling of data, including data quality control, will comply with regulatory 
guidelines (e.g., ICH GCP, and local regulations where applicable) and the sponsor’s 
or the CRO’s SOPs as well as provisions of the study-specific Data Management Plan. 
9.8.4. Archiving 
The investigator must make original study data (paper or electronic) accessible to the 
study monitor, other authorized sponsor representatives, and regulatory agency 
inspectors (e.g., US FDA) upon request. A file for each subject must be maintained 
that includes the signed ICF and copies of all source documentation related to that 
subject. The investigator must ensure the reliability and availability of source 
documents from which the information on the CRF was derived. 
Subject identity information recorded will be maintained for at least 15 years on the 
subject confidentiality log or longer if required by local regulations. 
Investigators must maintain all study documentation for at least 2 years following the 
approval of the drug, or until 2 years after the investigational drug program is

discontinued, or longer if required by local regulations. Study documentation includes 
all essential documents as defined in ICH E6 Guidelines for GCP. The sponsor or 
designee will notify the investigator when any records may be discarded, but 
investigators must comply with local regulations. 
9.9. 
Monitoring 
The study will be monitored to ensure that the study is conducted and documented 
properly according to the protocol, GCP, and all applicable regulatory requirements.  
On-site visits will be made at appropriate times during the period of the study. 
Monitors must have direct access to source documentation in order to check the 
consistency of the data recorded in the CRFs. 
The investigator will make available source documents, medical records, and source 
data necessary to complete CRFs to the monitor. In addition, the investigator will 
work closely with the monitor and, as needed, provide them appropriate evidence that 
the conduct of the study is being done in accordance with applicable regulations and 
GCP guidelines. 
9.10. Protocol Amendments, other Changes in Study Conduct 
9.10.1. Protocol Amendments 
Any changes to the study protocol will be addressed in a Protocol Amendment which 
will receive IEC approval before implementation thereof. 
 
9.10.2. Other Changes in Study Conduct 
Any other changes to the study conduct or statistical analyses will be described in the 
clinical study report. 
9.11. Quality Control and Quality Assurance 
The sponsor or its designee will perform the quality assurance and quality control 
activities of this study; however, responsibility for the accuracy, completeness, and 
reliability of the study data presented to the sponsor lies with the investigator 
generating the data. 
Audits may be conducted at the discretion of the sponsor as part of the 
implementation of quality assurance to ensure that the study is being conducted in 
compliance with the protocol, SOPs, GCP, and all applicable regulatory requirements. 
Audits will be independent of and separate from the routine monitoring and quality 
control functions. If such an audit occurs, the investigator must agree to allow access 
to required subject records. By signing this protocol, the Investigator grants 
permission to personnel from the sponsor, its representatives, and appropriate 
regulatory authorities for on-site monitoring of all appropriate study documentation, 
as well as on-site review of the procedures employed in CRF generation, where 
clinically appropriate.

11.2. Appendix 2 – Declaration of Helsinki 
 
WORLD MEDICAL ASSOCIATION (WMA) DECLARATION OF HELSINKI 
Ethical Principles for Research Involving Human Subjects 
Adopted by the 18th WMA General Assembly, Helsinki, Finland, June 1964 
and amended by the: 
29th WMA General Assembly, Tokyo, Japan, October 1975 
35th WMA General Assembly, Venice, Italy, October 1983 
41st WMA General Assembly, Hong Kong, September 1989 
48th WMA General Assembly, Somerset West, Republic of South Africa, October 1996 
52nd WMA General Assembly, Edinburgh, Scotland, October 2000 
53rd WMA General Assembly, Washington DC, USA, October 2002 (Note of Clarification added) 
55th WMA General Assembly, Tokyo, Japan, October 2004 (Note of Clarification added) 
59th WMA General Assembly, Seoul, Republic of Korea, October 2008 
64th WMA General Assembly, Fortaleza, Brazil, October 2013 
 
Preamble 
1.         The World Medical Association (WMA) has developed the Declaration of Helsinki as a 
statement of ethical principles for medical research involving human subjects, including research on 
identifiable human material and data. 
            The Declaration is intended to be read as a whole and each of its constituent paragraphs should 
be applied with consideration of all other relevant paragraphs. 
2.         Consistent with the mandate of the WMA, the Declaration is addressed primarily to physicians. 
The WMA encourages others who are involved in medical research involving human subjects to adopt 
these principles.  
General Principles 
3.         The Declaration of Geneva of the WMA binds the physician with the words, “The health of my 
patient will be my first consideration,” and the International Code of Medical Ethics declares that, “A 
physician shall act in the patient's best interest when providing medical care.” 
4.         It is the duty of the physician to promote and safeguard the health, well-being and rights of 
patients, including those who are involved in medical research. The physician's knowledge and 
conscience are dedicated to the fulfillment of this duty. 
5.         Medical progress is based on research that ultimately must include studies involving human 
subjects. 
6.         The primary purpose of medical research involving human subjects is to understand the causes, 
development and effects of diseases and improve preventive, diagnostic and therapeutic interventions 
(methods, procedures and treatments). Even the best proven interventions must be evaluated 
continually through research for their safety, effectiveness, efficiency, accessibility and quality. 
7.         Medical research is subject to ethical standards that promote and ensure respect for all human 
subjects and protect their health and rights. 
8.         While the primary purpose of medical research is to generate new knowledge, this goal can 
never take precedence over the rights and interests of individual research subjects. 
9.         It is the duty of physicians who are involved in medical research to protect the life, health, 
dignity, integrity, right to self-determination, privacy, and confidentiality of personal information of 
research subjects. The responsibility for the protection of research subjects must always rest with the 
physician or other health care professionals and never with the research subjects, even though they 


 
 
Protocol No: SCB01A-22 
 
 
Version 1.0; 19-Dec-2016

Page 66 of 69 
have given consent. 
10.       Physicians must consider the ethical, legal and regulatory norms and standards for research 
involving human subjects in their own countries as well as applicable international norms and 
standards. No national or international ethical, legal or regulatory requirement should reduce or 
eliminate any of the protections for research subjects set forth in this Declaration. 
11.       Medical research should be conducted in a manner that minimises possible harm to the 
environment. 
12.       Medical research involving human subjects must be conducted only by individuals with the 
appropriate ethics and scientific education, training and qualifications. Research on patients or healthy 
volunteers requires the supervision of a competent and appropriately qualified physician or other health 
care professional. 
13.       Groups that are underrepresented in medical research should be provided appropriate access to 
participation in research. 
14.       Physicians who combine medical research with medical care should involve their patients in 
research only to the extent that this is justified by its potential preventive, diagnostic or therapeutic 
value and if the physician has good reason to believe that participation in the research study will not 
adversely affect the health of the patients who serve as research subjects. 
15.       Appropriate compensation and treatment for subjects who are harmed as a result of 
participating in research must be ensured. 
Risks, Burdens and Benefits  
16.       In medical practice and in medical research, most interventions involve risks and burdens. 
           Medical research involving human subjects may only be conducted if the importance of the 
objective outweighs the risks and burdens to the research subjects. 
17.       All medical research involving human subjects must be preceded by careful assessment of 
predictable risks and burdens to the individuals and groups involved in the research in comparison with 
foreseeable benefits to them and to other individuals or groups affected by the condition under 
investigation. 
           Measures to minimise the risks must be implemented. The risks must be continuously monitored, 
assessed and documented by the researcher.  
18.       Physicians may not be involved in a research study involving human subjects unless they are 
confident that the risks have been adequately assessed and can be satisfactorily managed. 
           When the risks are found to outweigh the potential benefits or when there is conclusive proof of 
definitive outcomes, physicians must assess whether to continue, modify or immediately stop the 
study.            
Vulnerable Groups and Individuals 
19.       Some groups and individuals are particularly vulnerable and may have an increased likelihood 
of being wronged or of incurring additional harm. 
           All vulnerable groups and individuals should receive specifically considered protection. 
20.       Medical research with a vulnerable group is only justified if the research is responsive to the 
health needs or priorities of this group and the research cannot be carried out in a non-vulnerable group. 
In addition, this group should stand to benefit from the knowledge, practices or interventions that result 
from the research. 
Scientific Requirements and Research Protocols  
21.       Medical research involving human subjects must conform to generally accepted scientific 


 
 
Protocol No: SCB01A-22 
 
 
Version 1.0; 19-Dec-2016 
 
 
Confidential 
 
Page 67 of 69 
principles, be based on a thorough knowledge of the scientific literature, other relevant sources of 
information, and adequate laboratory and, as appropriate, animal experimentation. The welfare of 
animals used for research must be respected. 
22.       The design and performance of each research study involving human subjects must be clearly 
described and justified in a research protocol. 
           The protocol should contain a statement of the ethical considerations involved and should 
indicate how the principles in this Declaration have been addressed. The protocol should include 
information regarding funding, sponsors, institutional affiliations, potential conflicts of interest, 
incentives for subjects and information regarding provisions for treating and/or compensating subjects 
who are harmed as a consequence of participation in the research study. 
           In clinical trials, the protocol must also describe appropriate arrangements for post-trial 
provisions. 
Research Ethics Committees 
23.       The research protocol must be submitted for consideration, comment, guidance and approval to 
the concerned research ethics committee before the study begins. This committee must be transparent 
in its functioning, must be independent of the researcher, the sponsor and any other undue influence 
and must be duly qualified. It must take into consideration the laws and regulations of the country or 
countries in which the research is to be performed as well as applicable international norms and 
standards but these must not be allowed to reduce or eliminate any of the protections for research 
subjects set forth in this Declaration.  
           The committee must have the right to monitor ongoing studies. The researcher must provide 
monitoring information to the committee, especially information about any serious adverse events. No 
amendment to the protocol may be made without consideration and approval by the committee. After 
the end of the study, the researchers must submit a final report to the committee containing a summary 
of the study’s findings and conclusions.  
Privacy and Confidentiality  
24.       Every precaution must be taken to protect the privacy of research subjects and the 
confidentiality of their personal information. 
Informed Consent  
25.       Participation by individuals capable of giving informed consent as subjects in medical research 
must be voluntary. Although it may be appropriate to consult family members or community leaders, 
no individual capable of giving informed consent may be enrolled in a research study unless he or she 
freely agrees. 
26.       In medical research involving human subjects capable of giving informed consent, each 
potential subject must be adequately informed of the aims, methods, sources of funding, any possible 
conflicts of interest, institutional affiliations of the researcher, the anticipated benefits and potential 
risks of the study and the discomfort it may entail, post-study provisions and any other relevant aspects 
of the study. The potential subject must be informed of the right to refuse to participate in the study or 
to withdraw consent to participate at any time without reprisal. Special attention should be given to the 
specific information needs of individual potential subjects as well as to the methods used to deliver the 
information. 
           After ensuring that the potential subject has understood the information, the physician or another 
appropriately qualified individual must then seek the potential subject’s freely-given informed consent, 
preferably in writing. If the consent cannot be expressed in writing, the non-written consent must be 
formally documented and witnessed.       
           All medical research subjects should be given the option of being informed about the general 
outcome and results of the study. 


 
 
Protocol No: SCB01A-22 
 
 
Version 1.0; 19-Dec-2016

Page 68 of 69 
27.       When seeking informed consent for participation in a research study the physician must be 
particularly cautious if the potential subject is in a dependent relationship with the physician or may 
consent under duress. In such situations the informed consent must be sought by an appropriately 
qualified individual who is completely independent of this relationship. 
28.       For a potential research subject who is incapable of giving informed consent, the physician 
must seek informed consent from the legally authorised representative. These individuals must not be 
included in a research study that has no likelihood of benefit for them unless it is intended to promote 
the health of the group represented by the potential subject, the research cannot instead be performed 
with persons capable of providing informed consent, and the research entails only minimal risk and 
minimal burden. 
29.       When a potential research subject who is deemed incapable of giving informed consent is able 
to give assent to decisions about participation in research, the physician must seek that assent in 
addition to the consent of the legally authorised representative. The potential subject’s dissent should 
be respected. 
30.       Research involving subjects who are physically or mentally incapable of giving consent, for 
example, unconscious patients, may be done only if the physical or mental condition that prevents 
giving informed consent is a necessary characteristic of the research  group. In such circumstances the 
physician must seek informed consent from the legally authorised representative. If no such 
representative is available and if the research cannot be delayed, the study may proceed without 
informed consent provided that the specific reasons for involving subjects with a condition that renders 
them unable to give informed consent have been stated in the research protocol and the study has been 
approved by a research ethics committee. Consent to remain in the research must be obtained as soon 
as possible from the subject or a legally authorised representative. 
31.       The physician must fully inform the patient which aspects of their care are related to the 
research. The refusal of a patient to participate in a study or the patient’s decision to withdraw from the 
study must never adversely affect the patient-physician relationship. 
32.       For medical research using identifiable human material or data, such as research on material or 
data contained in biobanks or similar repositories, physicians must seek informed consent for its 
collection, storage and/or reuse. There may be exceptional situations where consent would be 
impossible or impracticable to obtain for such research. In such situations the research may be done 
only after consideration and approval of a research ethics committee. 
Use of Placebo 
33.       The benefits, risks, burdens and effectiveness of a new intervention must be tested against those 
of the best proven intervention(s), except in the following circumstances: 
           Where no proven intervention exists, the use of placebo, or no intervention, is acceptable; or 
           Where for compelling and scientifically sound methodological reasons the use of any 
intervention less effective than the best proven one, the use of placebo, or no intervention is necessary 
to determine the efficacy or safety of an intervention  
           and the patients who receive any intervention less effective than the best proven one, placebo, or 
no intervention will not be subject to additional risks of serious or irreversible harm as a result of not 
receiving the best proven intervention.  
           Extreme care must be taken to avoid abuse of this option. 
Post-Trial Provisions 
34.       In advance of a clinical trial, sponsors, researchers and host country governments should make 
provisions for post-trial access for all participants who still need an intervention identified as beneficial 
in the trial. This information must also be disclosed to participants during the informed consent process.

Page 69 of 69 
Research Registration and Publication and Dissemination of Results 
35.       Every research study involving human subjects must be registered in a publicly accessible 
database before recruitment of the first subject. 
36.       Researchers, authors, sponsors, editors and publishers all have ethical obligations with regard to 
the publication and dissemination of the results of research. Researchers have a duty to make publicly 
available the results of their research on human subjects and are accountable for the completeness and 
accuracy of their reports. All parties should adhere to accepted guidelines for ethical reporting. 
Negative and inconclusive as well as positive results must be published or otherwise made publicly 
available. Sources of funding, institutional affiliations and conflicts of interest must be declared in the 
publication. Reports of research not in accordance with the principles of this Declaration should not be 
accepted for publication. 
Unproven Interventions in Clinical Practice 
37.       In the treatment of an individual patient, where proven interventions do not exist or other 
known interventions have been ineffective, the physician, after seeking expert advice, with informed 
consent from the patient or a legally authorised representative, may use an unproven intervention if in 
the physician's judgement it offers hope of saving life, re-establishing health or alleviating suffering. 
This intervention should subsequently be made the object of research, designed to evaluate its safety 
and efficacy. In all cases, new information must be recorded and, where appropriate, made publicly 
available.

Pharmocokinetics Sampling will be bio-analyzed, and PK Parameters will be calculated by Protech 
Pharmaservices Corporation. All PK and PK parameter data will be provided to sponsor directly, no 
data handling, data listing nor statistical analysis on such data will be done by A2 Healthcare. 
 
 
8.6. PK Analysis 
 
The blood samples will be assayed for SCB01A and PK parameters (maximum plasma 
concentration [Cmax], clearance [CL], volume of distribution [Vd], half-life [t1/2], 
elimination constant [Kel], mean residence time [MRT] and time to maximum 
concentration [Tmax]) will be determined and presented graphically and descriptively (as 
appropriate). 
 
 
1.2 Objective response rate (ORR) Definition  
ORR is defined as the percentage of subjects who have achieved confirmed CR and PR during 
treatment phase, according to RECIST v1.1. Not-confirmed CR or PR, or withdraw for DLT are 
counted as non-responder. There are 5 subjects who are not evaluated due to clinical disease 
progression or AE/SAE. Tumor non-evaluable subjects are tend to be treatment failure and will also 
be counted as non-responder (Not Evaluable for Response), instead of counted as missing. 
 
 
Criteria for Evaluation: 
Efficacy measurements: 
 
 ORR is defined as the percentage of subjects who have achieved confirmed CR and 
PR during treatment phase, according to RECIST v1.1. Not-confirmed CR or PR, or 
withdraw for DLT are counted as non-responder. 
 
 
2 Mock-up Tables and Figures

The DSMB, composed of medical monitors (physicians experienced in oncology studies) and at 
least one statistician. Their responsibilities are to review and evaluate the data for safety, study 
conduct and progress, and make recommendations concerning the continuation, modification, 
or termination of study. Serial assessments of PK results also may be taken into account for 
safety evaluation. A neurologist will be invited to join DSMB meeting as a consultant when 
neurotoxicity occurred. 
The document review or meeting of DSMB will be held when the following scenarios: 
 A subject is not recovered from Grade 2 neurotoxicity over three weeks; 
 A subject revealed Grade 3 or above neurotoxicity; 
 After 10 evaluable subjects finished the study in Stage I

 Intention-to-treat (ITT) population: The ITT population consists of all subjects enrolled in the study and 
received at least one study treatment. 
 Per-protocol (PP) population: The PP population will consist of all subjects who  
(1) withdraw from study for DLT, or  
(2) completed at least 3 cycles of study treatment regimen, have measurable baseline disease and, at least, 
one post-baseline RECIST assessment (PD, SD, PR or CR). Subjects with a major protocol deviation or 
AE, deemed by the Medical Monitor to have an impact on the study endpoints, will be excluded from the 
PP population. 
 PK population: The PK population will consist of all subjects in stage I who received, at least, one dose of 
24 mg/m2 of SCB01A with sufficient post-dose bio-samples collected for PK profile characterization.

3 Change From Preceding Version of Statistical Analysis Plan 
 
3.1 SAP 2.0: Progression Free Survival (PFS) Estimation 
For Progression Free Survival, missing data will be estimated as the time from treatment onset date 
to date of last implementation of radiological image assessment +1 or estimated as ‘1’ if no post-
treatment tumor assessment available. Estimating missing data as censored on Day 1 shall be rather 
conservative than omitting the missing ones.

6.1. Efficacy Measurements 
 
Subjects will be considered evaluable for tumor assessment in this study if they fulfill the 
criteria for evaluation according to RECIST v1.1, i.e., those subjects who undergo a baseline 
disease assessment within 4 weeks of treatment initiation, and who undergo at least 1 
disease assessment on study (the following should be revised if revision in corresponding 
part in synopsis is accepted) . 
• 
PFS is defined as the time from the start of treatment up to the date of first progression 
based on RECIST v1.1 or the date of death, whichever comes first.  
 
 
3.2 SAP 3.0: Response Evaluation 
There are 5 subjects who are not evaluated due to clinical disease progression or AE/SAE. The 
subjects will be counted as ‘Not Evaluable for Response’ if no any post-treatment radiological 
image assessments. Each patient will be assigned one of the following categories: 
1. Complete response 
2. Partial response 
3. Stable disease 
4. Progression disease 
5. Not Evaluable for Response.
