Study Summary

This trial will test a new cancer drug to see if it is safe and effective.

Who is the study for?
This trial is for adults with advanced or metastatic solid tumors like NSCLC, HNSCC, GC/GEJ, ESCC who've had no luck with standard treatments. They should be relatively healthy (ECOG 0-1), have a life expectancy of at least 12 weeks, and good organ function. People can't join if they've recently used other investigational drugs or therapies, had major surgery or certain cardiovascular issues.Check my eligibility
What is being tested?
The study tests MCLA-129 alone in patients with various advanced cancers to find the maximum tolerated dose and/or recommended phase two dose. It's an early-phase trial that starts by giving small doses to a few people and increasing it for new groups until doctors find the best dose.See study design
What are the potential side effects?
Possible side effects include typical reactions to cancer therapy such as fatigue, nausea, skin reactions at injection sites, allergic responses to proteins in the drug (like rashes), liver enzyme changes indicating stress on the liver, and potential impact on blood cell counts.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
To determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) of single agent MCLA-129 in patients with NSCLC, GC/GEJ adenocarcinoma, HNSCC or ESCC, with disease progression after prior therapy for advanced/metastatic disease.
To evaluate the ORR of MCLA-129 alone or in combination with Osimertinib in molecularly defined populations of advanced/metastatic solid tumors.
Secondary outcome measures
Area under the concentration versus time curve [AUC0-∞]
Area under the concentration versus time curve from time zero to time t [AUC0-t]
Half-life [t1/2]
