Criteria
Key Inclusion Criteria:
- Measurable disease per RECIST v1.1. For Cohort G participants must have at least 1 measurable lesion, and for Part 3 (Cohorts E, F and H) participants must have at least 2 measurable lesions to safely perform mandatory pre & on-treatment biopsy.
- Life expectancy greater than or equal to 12 weeks.
- For Part 2 exclusively: While it is highly preferred to enroll subjects who are naïve to PD-1 inhibitors into a Part 2 dose escalation cohort, this is not an enrollment requirement. However, subjects who enroll into a Part 2 safety expansion cohort must be naïve to PD-1 inhibitors. If such subject is unable to meet this requirement but otherwise remains a good candidate for study enrollment, the Investigator should discuss with the Sponsor whether the subject may be enrolled.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- Adequate cardiovascular, hematological, liver, and renal function.
-
Histologically or cytologically confirmed diagnosis of advanced and/or metastatic solid tumors with at least one tumor lesion with location accessible to safely biopsy per clinical judgment of the Investigator.
- Caution: Cohort D only patients with KRAS mutant colon cancer have not typically benefitted from the addition of cetuximab in earlier lines of therapy.
- Caution: Cohorts E & F enrollment will include only patients with tumors for which anti-PD(L)1 as single agent or in combination treatments are approved.
- Caution: For Cohort H, the participant must have received at least one prior line of therapy for metastatic melanoma and/or does not have any standard of care (SoC) treatment option or participant declines or is intolerant to be treated with SoC treatment.
- Subjects with advanced or metastatic solid tumors who have refused SoC; or for whom no reasonable SoC exists that would confer clinical benefit; or for whom standard therapy is intolerable, not effective, or not accessible.
- Prior anti-cancer therapy is allowed as long as any treatment related toxicity is resolved to an appropriate level.
- Females of childbearing potential and men who are not surgically sterile must agree to use medically-accepted method of birth control during the study and for at least7 days (for Cohorts A, B, G and H), at least 2 months (for Cohort D), or at least 4 months (for Cohorts C, E and F) for females, and for at least 3 days for males [corresponding to the time needed to eliminate study intervention] after the last dose of study intervention.
- [Females] Negative serum pregnancy test within 7 days prior to initiating study treatment in premenopausal women and women less than 12 months after menopause.

- Concurrent therapy with any other investigational agent, vaccine, or device. Concomitant participation in observational studies is acceptable after Sponsor approval.
- For Cohort D only: patients with symptomatic keratitis and/or symptomatic dry eye should be excluded from enrollment. Patients who wear contact lenses should be advised to avoid contact lenses use as it could result in keratitis.
