irradiated; if the measurable lesion(s) have been irradiated, clear progression must

cetuximab given as palliative treatment or progressive disease within 1 year if
platinum-based chemotherapy was given as a part of the multimodal curative treatment.
Patients pre-treated with anti-PD1/anti-PDL1 are allowed.
- ECOG performance status 0 -1 with a life expectancy of at least 12 weeks.

- International Normalized Ratio (INR) or Prothrombin Time (PT) must be within the
normal ranges as per institution's standard. A window of 5% is allowed.

device, intrauterine hormone-releasing system, bilateral tubal occlusion, vasectomized
partner and sexual abstinence. For Men: condoms, sexual abstinence (the reliability of
