Summary

This is a Phase I/II, open-label, multi-center, multi-national, dose escalation, single agent
study to assess the safety, tolerability, PK, PD, immunogenicity and anti-tumor activity of
zenocutuzumab (MCLA-128) in patients with solid tumors harboring an NRG1 fusion (eNRGy)

Objectives

Study Design :

This open label (all participants know the identity of the study drug), multicenter (more
than one study site), first-in-human study consisting of 2 parts. Part 1 is a dose escalation
and Part 2 is a dose expansion cohort. Part 1 has been completed.

Part 2 new patient populations examined:

- Group F: Patients with NSCLC with documented NRG1 fusion

- Group G: Patients with pancreatic adenocarcinoma with documented NRG1 fusion

- Group H: Patients with any other solid tumor with documented NRG1 fusion

For these new patient populations, Part 2 will further characterize the safety and
tolerability of the selected dose level of zenocutuzumab (MCLA-128), as well as assessment of
CBR, defined as the proportion of patients with a CR, PR or durable SD (SD for at least 24
weeks in duration). For the new patient populations, overall response rate (ORR) and duration
of response (DOR) will be described.

The study consists of 3 periods: Screening period (up to 28 days prior to the first dose of
study drug); Treatment period (treatment cycles of 28 days); and Follow Up period (through 30
days after the last dose and quarterly checks for survival data for up to 2 years).
Participants' safety will be monitored throughout the study.

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments.
