Purpose
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.
Detailed Description
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 cancer 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 12
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.
Number of Sites:
Up to 40 sites are estimated to be involved during Parts 1 and 2 of the study. Additional
sites may be added to ensure there is an acceptable enrollment rate or to replace
non-enrolling/withdrawn sites.

normal (ULN) and total bilirubin ≤1.5 x ULN; in cases of metastatic liver involvement,
ALT/AST ≤5 x ULN and total bilirubin ≤2 x ULN will be allowed; in cases of antecedents
of Gilbert's syndrome when total bilirubin ≤3.0 x ULN or direct bilirubin ≤1.5 x ULN
will be allowed;
- Estimated glomerular filtration rate (GFR) of >30 mL/min
- Able to provide a tumor biopsy sample (fresh strongly preferred or else archival);

- Fertile patients must use effective contraception during and for 6 month after
completion of study therapy;
- Patients must have received prior standard therapy appropriate for their tumor type
and stage of disease, or in the opinion of the Investigator, would be unlikely to
tolerate or derive clinically meaningful benefit from appropriate standard of care
therapy;
- Locally-advanced unresectable or metastatic solid tumor malignancy with documented
NRG1 gene fusion, identified through molecular assays such as PCR, next generation
sequencing-based assays [DNA or RNA], or FISH as routinely performed at CLIA or other
similarly-certified laboratories.
Exclusion Criteria:
- Pregnant or lactating;
- Presence of an active uncontrolled infection or an unexplained fever;
- Known hypersensitivity to any of the components of MCLA-128;
- Known HIV, active Hepatitis B or Hepatitis C; patients treated for Hepatitis C and
have undetectable viral loads are eligible
- Known symptomatic or unstable brain metastases;
- Patients with leptomeningeal metastases
- Presence of congestive heart failure or Left Ventricular Ejection Fraction<50% or
history of significant cardiac disease, unstable angina, myocardial infarction or
ventricular arrhythmia requiring medication.

carcinoma in situ of the uterine cervix) unless the tumor was treated with curative
intent more than 2 years prior to study entry;
- Presence of any other medical or psychological condition deemed by the Investigator to
be likely to interfere with a patient's ability to sign informed consent, cooperate or
participate in the study, or interfere with the interpretation of the results.
