Clinical Trial Summary

This protocol for Varlitinib is developed for the treatment of Biliary Tract Cancer. Varlitinib (also known as ASLAN001) is a small-molecule, adenosine triphosphate competitive inhibitor of the tyrosine kinases - epidermal growth factor receptor (EGFR), human epidermal growth factor receptor (HER)2, and HER4. Varlitinib may be beneficial to subjects with cancer by simultaneous inhibition of these receptors. The purpose of this study is to determine the safety and efficacy of Varlitinib in combination with capecitabine for the treatment of Biliary Tract Cancer. Treatment groups are Varlitinib+capecitabine and Placebo + capecitabine

Eligibility

Inclusion Criteria:

Subjects will be eligible for the study if they:

1. Are of or older than the legal age in the respective countries at the time when written informed consent is obtained

2. Have histologically or cytologically confirmed advanced (unresectable) or metastatic biliary tract cancer, including intrahepatic or extrahepatic cholangiocarcinoma (CCA), gallbladder cancer and carcinoma of Ampulla of Vater. This includes clinical diagnosis of biliary tract cancer with histological confirmation of adenocarcinoma.

3. Have received and failed one and only one prior line of systemic treatment for advanced or metastatic disease with radiologic evidence of disease progression. This prior line of systemic treatment must also contain gemcitabine

4. Have received at least 6 doses of gemcitabine containing treatment in first line (Adjuvant therapy is not regarded as 1st line therapy)

5. Have radiographically measurable disease based on Response Evaluation Criteria in Solid Tumours (RECIST) v1.1 as assessed by Independent Central Review (ICR) (For Part 1)

6. Have no evidence of biliary duct obstruction, unless obstruction is controlled by local treatment or, in whom the biliary tree can be decompressed by endoscopic or percutaneous stenting with subsequent reduction in bilirubin to below or equal to 1.5 × upper level of normal (ULN)

7. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

8. Are able to understand and willing to sign the informed consent form

9. Have adequate organ and hematological function:

1. Hematological function, as follows:

• Absolute neutrophil count (ANC) = 1.5 × 109/L

• Platelet count = 100 × 109/L

2. Renal functions, as follows:

• Estimated glomerular filtration rate or creatinine clearance > 50 mL/min/1.73m2

3. Hepatic function, as follows:

• Aspartate aminotransferase and alanine aminotransferase = 5 × ULN

Exclusion Criteria:

Subjects will be ineligible for the study if they:

1. Are currently on or have received anti-cancer therapy within the past 3 weeks before receiving the first dose of study medication

2. Are currently on or have received radiation or local treatment within the past 3 weeks for the target lesion(s) before receiving the first dose of study medication

3. Have evidence of multiple (= 2) peritoneal metastases or ascites at baseline as assessed by ICR (For Part 1). (Ascites which can be attributed by non-malignant causes is not excluded. Minimal ascites, which does not require paracentesis is permitted.)

4. Have had major surgical procedures within 14 days prior to first dose of study medication

5. Have a known metastatic brain lesion(s), including asymptomatic and well controlled lesion(s)

6. Have malabsorption syndrome, diseases significantly affecting gastrointestinal function, resection of the stomach or small bowel, or difficulty in swallowing and retaining oral medications which in the opinion of the Investigator could jeopardize the validity of the study results

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective Response Rate (ORR) - Part 1	Part 1: The ORR was defined as the number (%) of subjects with = 1 visit response of complete response (CR) or partial response (PR). Data obtained up until progression, or until last evaluable assessment in the absence of progression, was included in the assessment of ORR, regardless of whether subjects discontinued treatment or received a subsequent therapy prior to progression. Best overall RECIST Response (BOR) was calculated based on the overall visit responses from each RECIST assessment, i.e. the best response a subject had following randomization and prior to RECIST progression or the last evaluable assessment in the absence of RECIST progression. Categorization of BOR was based on the RECIST criteria using the following response categories: CR, PR, stable disease (SD), progressive disease (PD) and not evaluable (NE).	Data obtained up until progression, or until last evaluable assessment in the absence of progression, regardless of whether subjects discontinued treatment or received a subsequent therapy prior to progression, up to 2 years.
Primary	Progression-free Survival (PFS) - Part 1	Part 1: Progression-free survival (PFS) was defined as the time from randomization (or starting treatment for the Safety Lead-in) until the date of objective disease progression or death (by any cause in the absence of disease progression) regardless of whether the subject withdrew from randomized therapy or received another antitumor therapy prior to disease progression. Subjects who did not experience disease progression or died at the time of analysis were censored at the time of the latest date of assessment from their last evaluable RECIST assessment. However, if the patient progressed or died after = 2 missed visits (12 weeks ± 5 days maximum), the subject was censored at the time of the latest evaluable RECIST assessment. The PFS time was based on the scan/assessment dates rather than visit dates.	Time from randomization until date of objective disease progression or death (by any cause in absence of disease progression) regardless of whether subject withdrew from randomized therapy or received another antitumor therapy prior to PD, up to 2 years.
Secondary	Object Response Rates (ORR) - Safety Lead-In	The ORR rate was defined as the number (%) of subjects with = 1 visit response of complete response (CR) or partial response (PR). Data obtained up until progression, or until last evaluable assessment in the absence of progression, was included in the assessment of ORR, regardless of whether subjects discontinued treatment or received a subsequent therapy prior to progression. In all study parts, the primary assessment of ORR was based on the Full Analysis Set (FAS).	Data obtained up until progression, or until last evaluable assessment in absence of progression, regardless of whether subjects discontinued treatment or received a subsequent therapy prior to progression, up to 2 years.
Secondary	Overall Survival (OS) - Part 1	Part 1: Overall survival (OS) was defined as the time from the date of randomization until death due to any cause. Any subject not known to have died at the time of the data cut-off was censored based on the last recorded date on which the subject was known to be alive.	Time from the date of randomization until death due to any cause, up to 2 years
Secondary	Overall Survival (OS) - Safety Lead-In	Part 1: Overall survival (OS) was defined as the time from the date of randomization until death due to any cause. Any subject not known to have died at the time of the data cut-off was censored based on the last recorded date on which the subject was known to be alive.	Time from the date of randomization until death due to any cause, up to 2 years
Secondary	Duration of Response (DoR) - Part 1	Part 1: Duration of response (DoR) was defined as the time from the date of first documented response until the date of documented PD or death in the absence of disease progression. The end of the response should have coincided with the date of disease progression or death from any cause used for the PFS endpoint.; For Part 1, DoR was calculated based on data from the ICR of radiological data.	Time from the date of first documented response until the date of documented PD or death in the absence of disease progression, up to 2 years
Secondary	Disease Control Rate DCR - Part 1	Part 1: DCR rate was defined as the number (%) of subjects with = 1 visit response of CR or PR, or with SD for a minimum of 12 weeks (± 5 days) from randomization. Data obtained up until progression, or until last evaluable assessment in the absence of progression, were included in the assessment of DCR, regardless of whether subjects discontinued treatment or received a subsequent therapy prior to progression. For all study parts, the primary assessment of DCR was based on the FAS.; For Part 1, DCR was calculated based on data from the ICR	Number (%) of subjects with = 1 visit response of CR or PR, or with SD for a minimum of 12 weeks (± 5 days) from randomization.
Secondary	Tumor Size - Part 1	Part 1: The percentage change from baseline in tumor size at Week 12 (%?TSWk12) was a secondary endpoint for Part 1 and was used to present waterfall plots of the target lesion data in the Evaluable for Response (EFR) Population	Week 12
