Summary

This trial investigates a new drug called GEN1119 for people with certain solid tumors that have not improved with standard treatments or for whom no standard treatment exists. The study is divided into parts: first, to find safe and effective doses, then to test those doses in more people with specific cancer types. All participants receive the active drug, and the trial monitors safety and tumor response over about 18 months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
GEN1119
What this could lead to
If successful, this could provide a new treatment option for people with solid tumors that have not responded to standard therapies.
What could go wrong
This is an early-stage trial, so the drug may not be effective or could have unexpected side effects. The results are preliminary and may not lead to a widely available treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Key Inclusion Criteria: * Have histologically or cytologically confirmed diagnosis of protocol-specified solid tumours. * Have progressed on standard of care (SoC) therapy applicable for the tumor type, or for whom there is no available SoC therapy likely to provide clinical benefit, and for whom experimental therapy with GEN1119 may be a suitable option in the opinion of the investigator. * Have measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. * Have acceptable laboratory test results before GEN1119 administration per protocol Key Exclusion Criteria: * Prior treatment with certain protocol-defined therapy. * Prior treatment with T-cell engagers, chimeric antigen receptor T-cell (CAR-T-cell) therapies, other protocol defined therapies, or other therapeutic moieties targeting certain protocol-defined molecules. * Treatment with an anticancer agent within 4 weeks or within 5 half lives of the drug, whichever is shorter, but not within 2 weeks before Cycle 1 Day 1 (C1D1). * Has clinically significant toxicities from previous anticancer therapies that have not resolved to baseline levels or to Grade 1 or lower, except for anorexia, hyperthyroidism, hypothyroidism, and peripheral neuropathy, which must have recovered to ≤ Grade 2. There is no limitation for alopecia from previous therapies. * Participant should not have active Hepatitis B infection. Participants with prior infections or chronic infections are allowed if monitored or treated as per local SOC and are negative for hepatitis B virus (HBV) DNA measured viral load. * Hepatitis C virus (HCV): Known active HCV infection (defined as positive for HCV ribonucleic acid \[RNA\] \[qualitative\]). Note: Other protocol-defined Inclusion and Exclusion criteria may apply.
