|Condition or disease||Intervention/treatment||Phase|
|Solid Tumor, Adult||Drug: Pembrolizumab 25 MG/ML(MK-3475)||Phase 1 Phase 2|
This is a Phase 1/2a, multicenter, dose-finding, consecutive-cohort, open-label trial of BI-1206 in combination with pembrolizumab in subjects with advanced solid tumors who have previously received treatment with a PD-1/PD-L1 immune checkpoint inhibitor.
The trial will consist of 2 main parts: Phase 1 (with dose escalation cohorts and selection of the RP2D), and Phase 2a (with 3 expansion cohorts at the RP2D).
Subjects in each phase will initially receive 3 planned doses of therapy with BI-1206 in combination with pembrolizumab.
Subjects who show clinical benefit (CR, PR or SD) at the Week 9 Visit may continue on combination therapy. Starting at Week 10, these subjects will receive infusions every 3 weeks for up to 32 additional doses or up to 2 years from first dose of BI-1206 therapy or until progression.

Pembrolizumab 200mg administrated IV every third week as a fixed dose will be used in Phase I and IIa
- Documenting AEs and SAEs and determining causality in relation to BI-1206 and/or pembrolizumab [ Time Frame: Up to 2 year ]Assess the safety and tolerability profile of increasing doses of BI-1206 in combination with pembrolizumab, graded according to National Cancer Institute [NCI]-CTCAE version 4.0
- Determining the MTD of BI-1206 at the same dose level experiencing a BI-1206 or pembrolizumab-related or possibly related dose-limiting toxicity (DLT) [ Time Frame: During the 42-day treatment period on induction therapy ]Select the RP2D dose for BI-1206 using mTPI-2 design.
- Evaluation of PK parameters for BI-1206. Maximum observed plasma concentration (Cmax) [ Time Frame: Up to 2 year ]Study the PK profile of BI-1206 according to a non-compartmental analysis using a validated software
- Evaluation of PK parameters for BI-1206. Area under the plasma concentration-time curve (AUC) [ Time Frame: Up to 2 year ]Study the PK profile of BI-1206 according to a non-compartmental analysis using a validated software
- Evaluation of ADA response to BI 1206 [ Time Frame: Up to 2 year ]Assess the immunogenicity of BI-1206. Detection and characterization of antibodies to BI-1206 will be performed using a validated method and will be evaluated for BI-1206 serum concentration to enable interpretation of the antibody data.
- Measurement of CD32b receptor occupancy on B cells. [ Time Frame: Up to 2 year ]Evaluate the effect of BI-1206 administered in combination with pembrolizumab on CD32b receptor occupancy on B cells in subjects with advanced solid tumors.
- Assessment of best disease responses according to Immunological Response Evaluation Criteria in Solid Tumors (iRECIST). [ Time Frame: 8 weeks after first dose BI1206 and every 9 weeks for subjects who continue on therapy ]Initially assess possible anti-tumor activity of BI-1206 administered in combination with pembrolizumab 8 weeks after first dose of BI-1206 (i.e., the Week 9 Visit [including follow-up confirmation for progressive disease (PD)]) in subjects with advanced solid tumors. Anti-tumor activity will also be evaluated every 9 weeks for subjects whocontinue on therapy.
- Measurement of progression free survival. [ Time Frame: Up to 2 year ]Patients who complete a baseline and at least one post-treatment disease assessment will be evaluable.PFS will be measured from the date of administration of the first dose of BI-1206 to the first date of progression, date of death from any cause, or the last response assessment date, whichever comes first.
- Measurement of duration of objective response [ Time Frame: Up to 2 year ]Time-to-event estimates will be generated using the Kaplan-Meier method. In the context of this single arm study, these analyses will be only descriptive
- Measurement of objective response rate [ Time Frame: Up to 2 year ]ORR is defined as the percentage of subjects who achieved a response of CR or PR. ORR and the associated 2-sided 95% exact confidence limits will be provided
- Measurement of peripheral blood B-lymphocyte depletion. [ Time Frame: Up to 2 year ]Evaluate the effect of BI-1206 in combination with pembrolizumab measuring B Lymphocyutes CD19 in absolut value.
- Measurement of expression levels of immunological markers such as CD32b, PD-1 in tissue biopsies. [ Time Frame: Up to 2 year ]Study expression levels of immunological markers (e.g., CD32b, PD-1) in the tumor and study a potential correlation of levels of expression with clinical responses.
- Evaluate BI-1206 and pembrolizumab tumor penetrance in biopsies [ Time Frame: Up to 2 year ]Evaluate BI-1206 and pembrolizumab tumor penetrance in biopsies using immunohistochemistry
- Measurement of cytokine levels [ Time Frame: Up to 2 year ]Study the potential cause of infusion related reaction (IRR) by measure serum cytokine levels
- Measurement of serum cytokine levels and/or soluble CD32b. [ Time Frame: Up to 2 year ]• Study the potential cause of infusion related reaction (IRR), such as cytokine release and/or soluble CD32b
