Researchers are looking for other ways to treat locally advanced or metastatic colorectal cancer (mCRC) that is unresectable and has a gene mutation called KRAS G12C.

Standard (or usual) treatments for this type of colorectal cancer may include mFOLFOX6 with or without bevacizumab. Researchers want to learn if adding calderasib (the study medicine) and cetuximab to mFOLFOX6 can treat locally advanced or mCRC with the KRAS G12C mutation. Calderasib and cetuximab are targeted therapies.

The goals of this study are to learn:

* About the safety of calderasib with cetuximab and mFOLFOX6 and if people tolerate the treatments
* If people who receive calderasib with cetuximab and mFOLFOX6 live longer without mCRC growing or spreading compared to people who receive mFOLFOX6 with or without bevacizumab.

This is a Phase 1/2, open label, multiple cohort study to assess the safety and preliminary efficacy of SAR445877 as a monotherapy or in combination with other anticancer therapies for participants aged at least 18 years with advanced unresectable or metastatic solid tumors.

The study will include 2 parts:

A dose escalation Part 1: for finding the therapeutic dose(s) of SAR445877 in a monotherapy given every 2 weeks (Q2W) or weekly (QW) and in combination with other anticancer therapies when applicable.

A multicohort dose expansion/dose optimization Part 2: for the assessment of safety and preliminary efficacy of SAR445877 in monotherapy and in combination with cetuximab or with next generation aCTLA4 (ADG126) or with bevacizumab. 2 recommended doses for expansion/optimization of SAR445877 identified from dose escalation part 1 will be tested in different indications in monotherapy and in combination with other anticancer therapies as applicable.

Approximately 542 participants will be exposed to the study intervention:

* approximately 123 participants in part 1,
* up to 410 participants in expansion/dose optimization part (part 2)
* and up to 9 participants in Japan cohort F.

This phase III trial compares the effect of modified fluorouracil, leucovorin calcium, oxaliplatin, and irinotecan (mFOLFIRINOX) to modified fluorouracil, leucovorin calcium, and oxaliplatin (mFOLFOX) for the treatment of advanced, unresectable, or metastatic HER2 negative esophageal, gastroesophageal junction, and gastric adenocarcinoma. The usual approach for patients is treatment with FOLFOX chemotherapy. Chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Fluorouracil stops cells from making DNA and it may kill tumor cells. Leucovorin is used with fluorouracil to enhance the effects of the drug. Oxaliplatin works by killing, stopping, or slowing the growth of tumor cells. Some patients also receive an immunotherapy drug, nivolumab, in addition to FOLFOX chemotherapy. Immunotherapy may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Irinotecan blocks certain enzymes needed for cell division and DNA repair, and it may kill tumor cells. Adding irinotecan to the FOLFOX regimen could shrink the cancer and extend the life of patients with advanced gastroesophageal cancers.

This Phase II/III trial will evaluate the what kind of chemotherapy to recommend to patients based on the presence or absences of circulating tumor DNA (ctDNA) after surgery for colon cancer.

This is a Phase II, single arm study looking at the rate of major clinical response and non-operative management in Stage II and III colon cancer after 18 weeks (up to 6 cycles) of neoadjuvant dostarlimab.

The study will assess the safety and efficacy of BXQ-350 plus modified FOLFOX7 (mFOLFOX7) and bevacizumab in participants who have newly diagnosed metastatic adenocarcinoma of the colon/rectum. The study will also evaluate if the administration of BXQ-350 with mFOLFOX7 and bevacizumab may diminish oxaliplatin induced sensory neurotoxicity, enabling participants to receive the total and planned doses of mFOLFOX7.

All participants will receive BXQ-350 by intravenous (IV) infusion along with standard of care doses of mFOLFOX and bevacizumab. The study is divided into two stages: Stage 1 will be open label and will enroll participants at increasing dose levels of BXQ-350 in order to determine the Stage 2 dose. Stage 2 will be blinded; participants will receive BXQ-350 at the established Stage 1 dose or placebo.
