What side effects are associated with this type of intervention?

Common treatments for colorectal cancer include chemotherapy agents such as fluorouracil and irinotecan, often combined with targeted therapies like cetuximab and bevacizumab. These treatments can cause a range of side effects. Chemotherapy agents are associated with myelotoxicity, including neutropenia and thrombocytopenia, as well as gastrointestinal issues like nausea and diarrhea. Cetuximab can cause severe skin reactions, hypomagnesemia, and infusion-related reactions. Bevacizumab may lead to hypertension, proteinuria, and an increased risk of gastrointestinal perforation. These side effects highlight the importance of monitoring and managing adverse events during treatment.

What prior FDA approvals exist?

Historically, the FDA has approved several treatments for colorectal cancer, including chemotherapy agents like fluorouracil, oxaliplatin, and irinotecan, as well as targeted therapies such as cetuximab and bevacizumab. Cetuximab, an EGFR inhibitor, is specifically used in patients without KRAS, NRAS, or BRAF mutations. For KRAS G12C mutations, targeted therapies like GDC-6036 represent a newer approach, focusing on inhibiting the specific mutation driving the cancer's growth. This is part of an evolving landscape in colorectal cancer treatment, aiming to provide more personalized and effective options for patients with specific genetic profiles.

What other types of research exist?

For colorectal cancer patients, promising alternatives to GDC-6036 include treatments involving bevacizumab, cetuximab, and panitumumab for KRAS wild-type tumors. Additionally, CMAB009 combined with irinotecan has shown promise as a second-line treatment. These alternatives have demonstrated efficacy in clinical trials and may be considered in consultation with a healthcare provider.

Summary

This trial is testing a new drug called GDC-6036 in patients with advanced or metastatic solid tumors that have a KRAS G12C mutation. The drug works by blocking a faulty part of the cancer cells' genetic code to stop their growth.

Who is the study for?

This trial is for adults with advanced solid tumors that have a specific mutation called KRAS G12C. Participants must be able to use contraception and not donate eggs or sperm during the study. They can't join if they have serious heart or liver problems, active brain cancer spread, or issues absorbing medicine through their gut.

What is being tested?

The study is testing the safety and effects of a new drug named GDC-6036, alone or combined with other cancer drugs like Atezolizumab and Cetuximab. It's in early stages (Phase I) to find out how much of the drug can be given safely and how it might help patients.

What are the potential side effects?

Possible side effects include reactions at the injection site, fatigue, nausea, skin rash, increased risk of infections due to immune system changes caused by these medications. The exact side effects will vary depending on which drugs are used together.

Other Research

Colorectal cancer treatments often target specific genetic mutations to inhibit cancer growth and progression. For instance, KRAS G12C inhibitors like GDC-6036 specifically target the KRAS G12C mutation, which is a common driver in colorectal cancer, by blocking the mutant KRAS protein's activity, thereby halting tumor growth. This is crucial for patients as KRAS mutations are associated with poor prognosis and resistance to other treatments. Additionally, therapies targeting the epidermal growth factor receptor (EGFR) are used in patients without RAS mutations to prevent cancer cell proliferation. Anti-angiogenic agents, which inhibit blood vessel formation, are also employed to starve tumors of nutrients. Understanding these mechanisms helps in selecting the most effective treatment based on the tumor's genetic profile, improving patient outcomes.
