Brief Summary:
The drug investigated in the study is an antibody, GEN1047. Since this is the first study of GEN1047 in humans, the main purpose is to evaluate safety. Besides safety, the study will determine the recommended GEN1047 dose to be tested in a larger group of participants and assess preliminary clinical activity of GEN1047. GEN1047 will be studied in a broad group of cancer participants, having different kinds of solid tumors. All participants will get GEN1047. The study consists of two parts: Part 1 tests increasing doses of GEN1047 ("escalation"), followed by Part 2 ("expansion") which tests the recommended GEN1047 dose from Part 1.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Breast Cancer, Breast Neoplasms Endometrial Cancer, Endometrial Neoplasm Ovarian Cancer, Ovarian Neoplasms Squamous Non Small Cell Lung Cancer (NSCLC-SCC) | Biological: GEN1047 is a bispecific antibody that induces T-cell mediated cytotoxicity of B7H4-positive cells. | Phase 1 Phase 2 |
The trial is an open-label, multi-center safety trial of GEN1047. The trial consists of two parts: a dose escalation part ("escalation" - phase 1) and an expansion part ("expansion" - phase 2a). The goal of the dose escalation part is to find out if GEN1047 is safe in participants with specific solid tumors and to find the best dose(s). In the expansion part of the trial up to two doses of GEN1047 will be tested.

|---|---|
| Experimental: GEN1047 |
Biological: GEN1047 is a bispecific antibody that induces T-cell mediated cytotoxicity of B7H4-positive cells.
GEN1047 will be administered as an intravenous infusion. The dose-levels will be determined by the starting dose and the escalation steps taken in the trial. |
Primary Outcome Measures :
- Escalation: Number of Participants with Dose Limiting Toxicities [ Time Frame: From the first Cycle (Cycle length=21 days) in each cohort ]To determine the maximum tolerated dose (MTD) and/or maximum administered dose (MAD) and recommended phase 2 dose (RP2D) or doses, to be studied in expansion part. DLT will be graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) criteria version 5.0.
- Escalation: Number of Participants with Treatment Emergent Adverse Events (TEAEs) [ Time Frame: From first dose date up to end of the safety follow up period, 30 days after last dose ]An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. TEAE is defined as an AE occurring or worsening between the first dose of study drug and 30 days after the last dose received.
- Expansion: Objective Response Rate (ORR) [ Time Frame: Up to 5 years ]ORR is defined as percentage of participants with best overall response (BOR) of confirmed complete response (CR) or confirmed partial response (PR) based on RECIST v1.1.
Secondary Outcome Measures :
- Escalation and Expansion: Clearance [ Time Frame: Predose and postdose at multiple timepoints of each Cycle (Cycle length=21 days) ]
- Escalation and Expansion: Volume of Distribution (Vd) [ Time Frame: Predose and postdose at multiple timepoints of each Cycle (Cycle length=21 days) ]
- Escalation and Expansion: Area Under the Concentration-time Curve from Time 0 to Time of Last Dose (AUClast) [ Time Frame: Predose and postdose at multiple timepoints of each Cycle (Cycle length=21 days) ]
- Escalation and Expansion: Maximum (Peak) Plasma Concentration (Cmax) [ Time Frame: Predose and postdose at multiple timepoints of each Cycle (Cycle length=21 days) ]
- Escalation and Expansion: Time to Reach Cmax (Tmax) [ Time Frame: Predose and postdose at multiple timepoints of each Cycle (Cycle length=21 days) ]
- Escalation and Expansion: Plasma Trough (Pre-dose) Concentrations (Cthrough) [ Time Frame: Predose and postdose at multiple timepoints of each Cycle (Cycle length=21 days) ]
- Escalation and Expansion: Elimination half-life (t 1/2) [ Time Frame: Predose and postdose at multiple timepoints of each Cycle (Cycle length=21 days) ]
- Escalation and Expansion: Number of Participants with Anti-Drug Antibody (ADA) [ Time Frame: Up to 5 years ]
- Escalation: ORR [ Time Frame: Up to 5 years ]ORR is defined as percentage of participants with BOR of confirmed CR or confirmed PR based on RECIST v1.1.
- Escalation and Expansion: Duration of Response (DOR) [ Time Frame: Up to 5 years ]DOR is defined as the time from the first documented response to the first documented progression or death due to any cause.
- Escalation and Expansion: Time to response (TTR) [ Time Frame: Up to 5 years ]Time to response (TTR) is defined as the time from the date of Cycle 1 Day 1 (C1D1) to the first documented response of either confirmed CR or confirmed PR.
- Escalation and Expansion: Disease control rate (DCR) [ Time Frame: Up to 5 years ]The disease control rate (DCR) is defined as the percentage of participants with BOR of confirmed CR, confirmed PR, or SD according to RECIST v1.1
- Expansion: Progression Free Survival (PFS) [ Time Frame: Up to 5 years ]PFS is defined as the time from the date of C1D1 to the date of the first documented progression or death due to any cause, whichever occurs earlier according to RECIST v1.1.
- Expansion: Overall Survival (OS) [ Time Frame: Up to 5 years ]OS is defined as the time from date of C1D1 to date of death due to any cause.
- Expansion: Number of Participants with TEAEs [ Time Frame: From first dose date up to end of the safety follow up period, 30 days after last dose ]An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. TEAE is defined as an AE occurring or worsening between the first dose of study drug and 30 days after the last dose received.
