About
The goal of this first in human clinical trial is to test BI-1808 administered as single agent and in combination with pembrolizumab in subjects with advanced malignancies whose disease has progressed after standard therapy.
The main questions it aims to answer are:
- how safe and tolerable is BI-1808
- what is maximum tolerated or administrated dose
- to determine recommended dose for further clinical trials. Participants will receive infusions of with BI-1808 as a single agent, BI-1808 in combination with pembrolizumab and BI-1808 in combination with pembrolizumab and paclitaxel every 3 weeks.
For the purpose of this study, subjects with advanced malignancies includes subjects with advanced solid tumors and subjects with T-cell lymphoma (TCL),
Full description
This is a Phase 1/2a, dose-escalation, multicenter, first-in-human, consecutive-cohort, open-label study of BI-1808, as a single agent, in combination with pembrolizumab, and in BI-1808 in combination with pembrolizumab and paclitaxel in subjects with advanced malignancies, whose disease has progressed after standard therapy.
The study will consist of 2 phases: a Phase 1 with Parts A and B, and a Phase 2a with Parts A , B and C.
Phase 1 Part A consists of a dose escalation of BI-1808 as a single agent to evaluate safety and tolerability and to determine the RP2D as a single agent (sRP2D) in subjects with advanced malignancies whose disease has progressed after standard therapy.
Phase 1 Part B consists of a dose escalation of BI-1808 in combination with pembrolizumab to evaluate the safety and tolerability of the combination treatment and to allow selection of the RP2D for BI-1808 in combination with pembrolizumab (cRP2D) in subjects with advanced malignancies whose disease has progressed after standard therapy.
Phase 2a will assess BI-1808 administered as a single agent (Part A), in combination with pembrolizumab (Part B), and in combination with pembrolizumab and paclitaxel (Part C) at the respective hypothesized RP2D(s) determined in Phase 1. Phase 2a expansion will be conducted in indication specific signal seeking cohorts and indication specific Dose Optimization Cohorts) of subjects. The Phase 2a study aims to further evaluate the safety and tolerability of BI-1808 as monotherapy (Part A), in combination with pembrolizumab (Part B), and in combination with pembrolizumab and paclitaxel (Part C). Including characterization of the PK and PD profiles of BI-1808, evaluation of preliminary antitumor activity based on ORR, DoR, and progression-free survival (PFS) as assessed by RECIST v1.1 and iRECIST, and determination of the recommended Phase 2 dose (RP2D).
