Inclusion criteria

Inclusion criteria: 1. Age 18 years or older; 2. At least one measurable lesion according to RECIST v1.1 OR evaluable disease for a limited number of patients (up to 15) in Group H; 3. Performance status of ECOG 0, 1 or 2; 4. Estimated life expectancy of at least 12 weeks; 5. Toxicities incurred as a result of previous anti-cancer therapy resolved to 14 days or >5 half-lives prior to study entry, whichever is shorter. b. >14 days for radiotherapy. Note: A less than 1-week wash-out period is permitted only for palliative radiation to non-CNS disease with Sponsor approval. 7. Patient has recovered from prior surgery or other procedure or complication to =1.5 x 109/L without colony stimulating factor support for at least 7 days prior to Screening; b. Platelets >=75 x 109/L without transfusion support for at least 7 days prior to Screening; c. Hemoglobin >=8 g/dL or >=5 mmol/L; d. Alanine aminotransferase (ALT), aspartate aminotransferase (AST) 3 x ULN in the absence of underlying liver disease may be considered for enrollment upon Sponsor review and approval; in cases of antecedents of Gilberts syndrome when total bilirubin 30 mL/min based on the Cockroft-Gault formula; 9. Able to provide at baseline a mandatory tumor biopsy sample (FFPE), preferably a block; If safe/feasible, a fresh FFPE biopsy sample is preferred; archival tissue is acceptable (preferably not more than 2 years old); NOTE #1: For patients who received afatinib or other HER-targeting agents, a biopsy collected after the last line of treatment is strongly preferred to assess for mechanisms of acquired resistance. NOTE #2: For patients with a locally confirmed NRG1 gene fusion, when archival tissue is not available and collection of a fresh biopsy is not safe or feasible during the screening period, these patients will be allowed to enroll in the MCLA-128-CL01 trial provided they meet all other inclusion/exclusion criteria. 10. Negative pregnancy test results available as defined by a blood human chorionic gonadotropin (hCG) test during Screening and within 7 days of Cycle 1, Day 1 in women of childbearing potential (defined as women <=50 years of age or history of amenorrhea for <=12 months prior to study entry); NOTE: Women with amenorrhea associated with prior treatment with antineoplastic medications are still considered as being of child-bearing potential.; 11. Sexually active male and female patients of childbearing potential must agree to use one of the following highly effective methods of birth control during the entire duration of the study and for 6 months after final administration of MCLA-128: - co

Exclusion criteria

Exclusion criteria: 1. Pregnant or lactating; 2. Presence of an active uncontrolled infection or an unexplained fever greater than 38.5 Celsius degree during Screening up to the first scheduled day of dosing. At the discretion of the Investigator, patients with tumor fever or a clinically insignificant minor infection may be enrolled (i.e., mild upper respiratory infection); 3. Known hypersensitivity to any of the components of MCLA-128 or history of severe hypersensitivity reactions to human or humanized monoclonal antibodies, including therapeutic antibodies; 4. Patients with the following infectious diseases are excluded: a. known HIV b. active Hepatitis B infection (HBsAg positive) without receiving antiviral treatment Note: -Patients with active hepatitis B (HBsAg positive) must receive antiviral treatment with lamivudine, tenofovir, entecavir, or other antiviral agents, starting at least >= 7 days before the initiation of the study treatment. -Patients with antecedents of Hepatitis B (anti-HBc positive, HBsAg and HBV-DNA negative) are eligible. c. positive test for Hepatitis C ribonucleic acid (HCV RNA) Note: -Patients in whom HCV infection resolved spontaneously (positive HCV antibodies without detectable HCV-RNA) or those that achieved a sustained response after antiviral treatment and show absence of detectable HCV RNA >= 6 months (with the use of IFN-free regimens) or >= 12 months (with the use of IFN-based regimens) after cessation of antiviral treatment are eligible; NOTE: Patients without known or suspected HIV, Hepatitis B or Hepatitis C infection do not require specific viral testing during the screening period. 5. Known symptomatic or unstable brain metastases. Patients with asymptomatic brain metastases are eligible to participate if the metastases have been radiographically and clinically stable for at least one month. If on steroids for this indication, the patient must be on a stable dose for at least one month; 6. Patients with leptomeningeal metastases; 7. Previous or concurrent malignancy, excluding non-basal cell carcinoma of skin or carcinoma in situ of the uterine cervix unless the tumor was treated with curative or palliative intent and in the opinion of the Investigator, with Sponsor agreement, the previous or concurrent malignancy condition doesn't affect the assessment of safety and efficacy of the study drug; 8. Presence of congestive heart failure or LVEF <50% on the screening echocardiogram; or history or presence of any significant cardiovascular disease, including unstable angina or myocardial infarction within 12 months prior to screening, congestive heart failure (NYHA Class III or IV), or ventricular arrhythmia requiring medication; 9. Presence of any other medical or psychological condition deemed by the Investigator to be likely to interfere with a patients ability to sign informed consent, cooperate or participate in the study, or interfere with the interpretation of the results.
