Eligibility
Key inclusion criteria
Key

- 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.

- [Males] Agreement to refrain from donating or banking sperm during the treatment
period and for at least 3 days after last dose of study treatment.

- In Spain, Chile, and Argentina: Only cohorts G and H will be open to enrollment.

assessment of any study endpoints. Subjects with non-melanomatous skin cancer or
cervical cancer that has been curatively surgically resected are eligible.

- Any serious medical condition (including pre-existing autoimmune disease or
inflammatory disorder), laboratory abnormality, psychiatric condition, or any other
significant or unstable concurrent medical illness that in the opinion of the
Investigator would preclude protocol therapy or would make the subject inappropriate
for the study.

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
