Brief Summary:
The drug that will be investigated in the study is an antibody, GEN3009. Since this is the first study of GEN3009 in humans, the main purpose is to evaluate safety. Besides safety, the study will determine the recommended GEN3009 dose to be tested in a larger group of patients and assess preliminary clinical activity of GEN3009. GEN3009 will be studied in a broad group of cancer patients, having different kinds of lymphomas. All patients will get GEN3009 either as a single treatment (monotherapy) or in combination with another antibody-candidate for treatment of cancer in the blood. The study consists of two parts: Part 1 tests increasing doses of GEN3009 ("escalation"), followed by Part 2 which tests the recommended GEN3009 dose from Part 1 ("expansion").
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Diffuse Large B-cell Lymphoma Follicular Lymphoma Marginal Zone Lymphoma Small Lymphocytic Lymphoma Mantle Cell Lymphoma Chronic Lymphocytic Leukemia High-grade B-cell Lymphoma Primary Mediastinal Large B-cell Lymphoma | Biological: GEN3009 Biological: Epcoritamab | Phase 1 Phase 2 |
This trial will be conducted in 2 parts: Part 1 (Dose Escalation) and Part 2 (Dose Expansion). All subjects in Part 1 will receive GEN3009, administered at various dose levels in 28-day cycles. Dose Limiting Toxicity (DLT) will be assessed during the first treatment cycle of Part 1 and the Maximum Tolerated Dose (MTD) and/or Recommended phase 2 dose (RP2D) will be identified.
Subjects in Part 2 will be treated with the Part 1-defined RP2D of GEN3009. Some subjects will receive GEN3009 in combination of a fixed dose of another antibody-candidate. Subjects in Part 2 are assigned either to one of 3 groups: Part 2 Monotherapy (hereafter referred to as 'Part 2A'), Part 2 Combination Safety Run-in ('Part2B') or Part 2 Combination ('Part2C').
Various types of B-cell NHLs are studied, including diffuse large B cell lymphoma (DLBCL), high-grade B cell lymphoma (HGBCL), mantle cell lymphoma (MCL), primary mediastinal large B-cell lymphoma (PMBCL), follicular lymphoma (FL), marginal zone lymphoma (MZL) and chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL).
