About this trial

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 BI-1808 alone or combination with pembrolizumab 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),

Trial outcomes

Primary outcomes

1

Occurrence of adverse events (AEs)

AEs will be assessed by the investigators by severity and will be graded according to the NCI CTCAE v5.0 or higher and causality between AEs and the exposure to the study treatment.

Time frame
From the start of the study treatment for up to 2 years and 90 days.
2

Identify DLTs, determine the maximum tolerated dose and select a recommended Phase 2 dose (RP2D) of BI-1808, given via intravenous (IV) infusion, as a single agent (Phase 1, Part A), and in combination with pembrolizumab (Phase 1, Part B)

Select the RP2D dose for BI-1808ing mTPI-2 design.

Time frame
Up to 104 weeks (2 years)
3

Occurrence of serious adverse events (SAEs)

SAEs will be assessed by the investigators by severity and will be graded according to the NCI CTCAE v5.0 or higher and causality between SAEs and the exposure to the study treatment

Time frame
Up to 104 weeks (2 years)

Secondary outcomes

1

Evaluation of PK parameters for BI-1808. Maximum observed plasma concentration (Cmax)

Study the PK profile of BI-1808 according to a non-compartmental analysis using a validated software

Time frame
Up to 104 weeks (2 years)
2

Evaluation of ADA response to BI-1808 in serum with validated method

The detection and characterization of antibodies to BI-1808 will be performed using a validated method and will be evaluated for BI-1808 serum concentration to enable interpretation of the antibody data

Time frame
Up to 104 weeks (2 years)
3

Measurement of TNFR2 receptor occupancy on CD14+ and/CD16+ cells in serum with validated method

evaluate the receptor occupancy of BI-1808 as a single agent and in combination with pembrolizumab on T-cells expressing TNFR2 in absolute value

Time frame
Up to 104 weeks (2 years)
