Phase 1
Terminated
Conditions
P2: Biliary Tract Cancer
P1b: Advanced Solid Tumors
Interventions
Drug: CTX-009 (ABL001)
Registration Number
NCT04492033
Lead Sponsor
Handok Inc.
Brief Summary

This study is a Phase 1b/2 multi-center study to assess the safety, tolerability, pharmacokinetics of CTX-009 (ABL001) in combination with Irinotecan or Paclitaxel in patients with advanced or metastatic solid tumors.

Detailed Description

Phase 1b Study:

Indication of phase 1b study is the advanced or metastatic solid tumors (including, but not limited to, colorectal cancer, gastric cancer, and ovarian cancer).

Phase 2 Study:

Indication of phase 2 study is unresectable advanced, metastatic or recurrent biliary tract cancer (BTC) (including intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, gallbladder cancer, and ampullary carcinoma).

Primary Outcome Measures
NameTimeMethod
P1b: Proportion of subjects with Dose-Limiting Toxicity (DLT)From Day 1 until disease progression or Day 28, whichever came first

Number of subjects who experience DLT events during 28 days after first administration of CTX-009 (ABL001) and Irinotecan/Paclitaxel, divided by the number of DLT-evaluable subjects

P2: Objective response rate (ORR) of CTX-009 (ABL001) in combination with paclitaxel in patients with BTCUp to approximately 24 months

The proportion of subjects whose best overall response (BOR) is assessed to be complete response (CR) or partial response (PR) as per Independent Radiology Center's review

Secondary Outcome Measures
NameTimeMethod
Progression-free survival (PFS)Up to approximately 24 months

The time from the initiation of treatment to the first radiologic assessment that confirms progression of tumor or to death

Duration of response (DOR)Up to approximately 24 months

Time interval from first occurrence of a documented objective response to the time of disease progression

P2: Survival rate6 months and 12 months

The proportion of subjects who have survived at 6 months and 12 months from the initiation of treatment

Pharmacokinetics (PK) of CTX-009 (ABL001)Up to approximately 24 months

Serum concentrations of CTX-009 (ABL001) will be collected and analyzed to evaluate the PK of CTX-009 (ABL001)

Adverse Events (AEs)Up to approximately 24 months

Severity of AEs will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0

Objective response rate (ORR)Up to approximately 24 months

Proportion of subject with best overall response of complete response (CR) or partial response (PR) as per investigator's review

Disease control rate (DCR)Up to approximately 24 months

Proportion of subjects with a best overall response of complete response (CR), partial response (PR) or stable disease (SD)

Time to treatment failure (TTF)Up to approximately 24 months

Time interval from 1st administration of CTX-009 (ABL001) to the time of disease progression or discontinuation of CTX-009 (ABL001) due to whatever reason, whichever comes first

P2: Overall survival (OS)Up to approximately 24 months

Time from the initiation of treatment to death
