Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this trial is to measure the following in participants with solid tumors who receive GEN1047:

* The side effects seen with GEN1047
* What the body does with GEN1047 once it is administered
* What GEN1047 does to the body once it is administered
* How well GEN1047 works against solid tumors

The estimated trial duration for an individual participant is 8 months, consisting of a 28-day screening period, an estimated 3 month treatment period (the duration of treatment may vary for each participant), and an estimated 4 month post-treatment follow-up period (the duration of follow-up may vary for each participant). All participants will receive active drug; no one will be given placebo.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

GEN1047

Group Type EXPERIMENTAL

GEN1047 is a bispecific antibody that induces T-cell mediated cytotoxicity of B7H4-positive tumor cells.

Intervention Type BIOLOGICAL

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Criteria - Escalation Part:

* Participant must have histologically or cytologically confirmed solid tumor(s) in any of the following selected indications for which there is no further available standard therapy likely to confer clinical benefit (or participant is not a candidate or has previously refused such earlier available therapy), and for whom, in the opinion of the investigator, experimental therapy with GEN1047 may be beneficial (breast cancer, endometrial cancer, ovarian cancer, NSCLC-SCC.
* Participants with ovarian cancer must have documented progressive disease (PD) on or after last prior treatment and within 60 days of screening.
* Must be at least 18 years of age (or the legal age of consent in the jurisdiction in which the trial is taking place) on the day of signing informed consent.
* Must have either recurrence after, or progression on or lack of response to available relevant standard of care (SoC) anticancer therapies; or are deemed intolerant to or ineligible for, standard curative therapy in the recurrent setting.
* Must have at least 1 measurable lesion per RECIST v1.1. The measurable lesion(s) must be outside the field of radiation therapy (RT) if there was prior treatment with RT.
* Must have an Eastern Cooperative Oncology Group performance status (ECOGPS) score of 0 to 1 at Screening and on C1D1 pretreatment.
* Should provide a tumor tissue sample during the Screening period and prior to C1D1.
* Provide all tumor-assessing pre-trial CT scans since failure of last prior therapy.

Criteria - Expansion Part Stage 1, 1b and Stage 2:

* Participants must have documented PD according to RECIST v1.1 on or after last prior treatment with latest scan performed a maximum of 28 days prior to the first dose.
* Participant must have advanced (unresectable) or metastatic, histologically confirmed diagnosis (breast cancer, endometrial cancer, ovarian cancer.
* Must be a female and at least 18 years of age (or the legal age of consent in the jurisdiction in which the trial is taking place) at the time of consent.
* Must have at least 1 measurable lesion per RECIST v1.1 as assessed by local investigator.
* Must have an ECOG- PS score of 0 to 1 at Screening and on Cycle 1 Day 1 (C1D1) pretreatment.
* Must submit a tumor tissue sample during the Screening period and prior to C1D1.
* Provide all tumor-assessing pre-trial CT scans since failure of last prior therapy.

Exclusion Criteria

* Significant cardiovascular impairment within 6 months of the first dose of trial drug.
* Participant with new or progressive brain metastases or spinal cord compression.
* Participant has been exposed to any prior therapy with a compound targeting CD3 and/or B7H4 or cell based therapies.
* Current pneumonitis (any grade) including any radiological change of ongoing pneumonitis at baseline or history of non-infectious drug-, immune-, or radiation-related pneumonitis that required steroid.
