* To assess other indicators of anti-tumor activity.
* To assess the PK of SAR442720 with adagrasib, and the PK of adagrasib with SAR442720.
* Part 4

* To estimate the anti-tumor effects of SAR442720 with pembrolizumab.

This open label Phase 1 multicenter study was designed to evaluate the safety and maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of SAR442720 in combination with pembrolizumab in participants with solid tumors in Part 1.

In Part 2, in the expansion cohort (Cohort A) we assessed the antitumor activity and safety of SAR442720 combined with pembrolizumab in participants with metastatic 1L lung cancer.

In Part 3, we evaluated the safety, MTD, RP2D and antitumor activity of SAR442720 in combination with adagrasib in participants with lung cancer and KRAS G12C mutation.

In Part 4, we evaluated the impact of the formulations (formulation 1 and formulation 2) and of the food on the PK of SAR442720 when dosed in combination with pembrolizumab. The expected duration of study intervention for participants may vary, based on progression date; median expected duration of study per participant was estimated to be about 10 months in Part 1, Part 3 and Part 4 (up to 1 month for screening, a median of 6 months for treatment, and a median of 3 months for long term follow-up) and in Part 2 16 months (up to 1 month for screening, a median of 12 months for treatment and a median of 3 months for long term follow up.)

Eligibility Criteria:
Inclusion Criteria:

* Participants must be ≥ 18 years of age.
* Histologically proven diagnosis of advanced solid tumors.
* Participants must have one or more of the following molecular aberrations (Part 1): KRAS mutations and amplifications, BRAF Class 3 mutations, or NF1 LOF mutations.
* Participants must have following molecular aberration (Part 3A and 3B): - KRAS G12C mutation.
* At least 1 measurable disease per RECIST 1.1 criteria.
* Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
* Woman of childbearing potential must agree to follow contraceptive guidance.
* Capable of giving signed informed consent.

Exclusion Criteria:

* Predicted life expectancy \<3 months.
* Primary central nervous system (CNS) tumors.
* Symptomatic or impending cord compression. Stable CNS disease was allowed.
* History of cerebrovascular stroke or transient ischemic attack within previous 6 months.
* Prior solid organ or hematologic transplant.
* History or current retinal pigment epithelial detachment (RPED), central serous retinopathy, retinal vascular occlusion (RVO), neovascular macular degeneration.
* Any clinically significant cardiac disease.
* Active, known or suspected autoimmune disease.
* History of or current interstitial lung disease or pneumonitis.
* Receipt of a live-virus vaccination within 28 days, viral vaccine that do not contain live virus within 7 days of planned treatment start. Seasonal flu vaccines that do not contain live virus are permitted.
* Known infection with human immunodeficiency virus (HIV), known uncontrolled hepatitis B infection, active tuberculosis, or severe infection requiring parenteral antibiotic treatment.
* Inadequate hematologic, hepatic and renal function.
* Known second malignancy.
* Impairment of gastrointestinal function.
* Any unstable or clinically significant concurrent medical condition that would, in the opinion of the investigator, jeopardize the safety of a participant, impact their expected survival through the end of the study participation, and/or impact their ability to comply with the protocol.
* History of severe allergic reaction to any of the study intervention components.
