Clinical trial overview
The available trial data describe one interventional study of Zenocutuzumab, also listed as MCLA-128, in people with solid tumors.[1] The study is authorised and plans to include 452 participants.[1]
This trial is designed to learn whether the treatment is safe, how well it is tolerated, and whether it shows anti-tumor activity in selected patients.[1]
Who the trials are for
The main study includes patients with solid tumors, which are cancers that form a mass in body tissue.[1] Some trial groups focus on patients whose tumors have an NRG1 fusion, which is a specific gene change found by tumor testing.[1]
The brief summary shows that the trial includes several groups, and the NRG1 fusion groups are used to study anti-tumor activity and how long any response lasts.[1]
Trial phase and study design
This is a Phase 1/2 trial, which means it combines early safety testing with a closer look at whether the treatment may work.[1] The study is interventional, so participants receive the study treatment and researchers measure the results.[1]
In Part 1, the study aims to find the maximum tolerated dose and/or the maximum recommended dose of MCLA-128.[1] These are the dose levels that help researchers decide how much treatment can be given safely.[1]
What the trials measure
The main safety measures in Part 1 are adverse events and dose limiting toxicities.[1] Adverse events are unwanted medical problems during the study, and dose limiting toxicities are side effects that may limit treatment dose.[1]
For Part 2, the study looks at overall response rate, duration of response, and clinical benefit rate in several groups.[1] Overall response rate shows how many patients have tumor shrinkage or disappearance, while duration of response shows how long that benefit lasts.[1]
For the NRG1 fusion groups, the trial also measures overall response rate and duration of response using RECIST v1.1 as assessed by the local investigator.[1] RECIST v1.1 is a standard way to measure tumor changes on scans and exams.[1]
Study groups and patient groups
The study summary divides Part 2 into Groups A to E, F, G, and H, with different goals for each group.[1] Some groups are used to study safety and tolerability, while others are used to explore links between anti-tumor activity and disease-related biomarkers.[1]
For the NRG1 fusion groups, the main focus is on the strength and durability of anti-tumor activity in patients whose tumors carry that fusion.[1] This makes the trial especially relevant for patients with a specific tumor marker rather than all solid tumors.[1]
Trial summary
In the available data, there is one authorised Phase 1/2 trial of Zenocutuzumab in solid tumors, including patients with NRG1 fusion.[1] The study is testing safety, tolerability, dose finding, and early signs of anti-tumor activity.[1] It also measures how long any response lasts and how many patients benefit from treatment.[1]
