Brief Summary

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

The main purpose is to assess the safety and clinical activity of GEN1042 in combination with radiotherapy or GEN1042 in combination with radiotherapy and pembrolizumab as a treatment option for participants with metastatic solid tumors.

Detailed Description

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

The study will be conducted in two parts: Part 1 (dose-finding) and Part 2 (randomization).

Part 1 will evaluate the safety of immunoradiotherapy combinations and establish the dose(s) to be evaluated in Part 2.

Part 2 will evaluate the anti-tumor activity of immunoradiotherapy combinations at the established dose(s) from Part 1.

Participants in both parts are treated with one of the following combinations:

* Radiotherapy + GEN1042
* Radiotherapy + GEN1042 + Pembrolizumab

While participants in Part 1 are assigned sequentially (GEN1042 without pembrolizumab is investigated first), participants in Part 2 are randomized 1:1 in the two treatment arms.
