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 evaluate the safety, tolerability, pharmacokinetics (PK), anti-tumor activity and immunogenic potential of GEN1286 in participants with advanced solid tumors.

This trial consists of 2 parts:

* Part A: Dose escalation and dose level expansion
* Part B: Tumor-specific expansion with dose optimization

Intervention Model

SEQUENTIAL

No randomization will be performed in Part A (dose escalation- sequential assignment). In Part B (tumor-specific expansion- parallel assignment), participants in each cohort will be randomized with a 1:1 ratio to receive one of the expansion doses of GEN1286.
