What side effects are associated with this type of intervention?

Common side effects of treatments targeting the KRAS p.G12C mutation, such as sotorasib and adagrasib, include gastrointestinal issues (nausea, diarrhea), fatigue, liver enzyme elevations, and musculoskeletal pain. These side effects are generally manageable but can vary in severity. The D3S-001 trial, which is evaluating a similar targeted therapy, will likely observe comparable adverse effects, focusing on safety and tolerability in its early phases.

What prior FDA approvals exist?

The FDA has approved several drugs targeting KRAS mutations, particularly the KRAS p.G12C mutation. Sotorasib (Lumakras) was the first FDA-approved drug specifically targeting KRAS p.G12C mutation in non-small cell lung cancer (NSCLC). Another drug, adagrasib, is also being developed for similar indications. These drugs work by inhibiting the KRAS G12C protein, thereby blocking the signaling pathways that promote cancer cell growth. These treatments are similar to the investigational drug D3S-001, which is being studied for its efficacy in advanced solid tumors with the KRAS p.G12C mutation.

What other types of research exist?

Promising alternatives to D3S-001 for KRAS mutation patients include investigational agents targeting the KRAS pathway, such as adagrasib (MRTX849) and sotorasib (AMG 510). Both have shown efficacy in clinical trials for KRAS p.G12C mutant cancers. Additionally, combination therapies involving MEK inhibitors or other targeted agents may offer potential benefits.

Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Subject must have Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

Summary

This trial tests a new drug, D3S-001, taken daily for a few weeks, in patients with certain advanced cancers. The drug aims to block a faulty part of the cancer cells to stop or slow their growth.

Who is the study for?

This trial is for adults with advanced solid tumors that have a specific genetic change called KRAS p.G12C mutation. They must show measurable disease progression, be relatively fit (ECOG status of 0 or 1), and have good organ and marrow function. People can't join if they're still experiencing significant side effects from previous cancer treatments, are in other treatment studies, haven't waited long enough after past treatments, or have illnesses that could affect the study drug's action or their participation.

What is being tested?

The trial is testing D3S-001 as a solo treatment to see how safe it is and how well people tolerate it. It will also look at how the body processes the drug and its effect on tumors in patients with advanced solid tumors carrying the KRAS p.G12C mutation. The goal is to find out the best dose for Phase 2 trials.

What are the potential side effects?

Since this is a first-in-human study for D3S-001, potential side effects aren't fully known yet but may include typical reactions seen with cancer drugs such as nausea, fatigue, blood count changes, liver enzyme elevations, and possibly others based on how it affects tumor cells.

Other Research

KRAS p.G12C mutations are targeted by specific inhibitors that covalently bind to the mutant cysteine residue in the KRAS protein, locking it in an inactive GDP-bound state. This prevents the activation of downstream signaling pathways that promote tumor growth and survival. Treatments like sotorasib and adagrasib are examples of such inhibitors. These therapies are significant for KRAS p.G12C mutation patients because they offer a targeted approach to disrupt the oncogenic signaling driven by the mutant KRAS, potentially leading to better clinical outcomes compared to traditional chemotherapy.
