What is the purpose of this trial?

This trial tests a combination of two drugs, adagrasib (Krazati or MRTX-849) and olaparib (Lynparza), to determine their safety and tolerability in people with advanced solid tumors. Researchers aim to find the right dose for individuals whose cancers have specific genetic changes, known as KRAS G12C and/or KEAP1 mutations, which may influence cancer growth. It targets those with solid tumors who have already tried at least one other unsuccessful treatment. This trial may suit individuals whose cancer continues to progress despite previous treatments. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants a chance to be among the first to receive this new combination therapy.

Will I have to stop taking my current medications?

The trial requires a 2-week washout period (time without taking certain medications) for strong or moderate CYP3A inhibitors and a 5-week washout period for strong or moderate CYP3A inducers before starting the study treatment. If you are taking medications that fall into these categories, you may need to stop or switch them before participating.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that adagrasib, when used alone, is generally easy for patients to handle. One study produced good results without causing any serious side effects. Another study found that many patients responded well to adagrasib, experiencing positive effects without major safety concerns.

Olaparib is also known to be safe. The FDA has approved it for treating certain cancers, indicating its safety for many patients.

Currently, researchers are studying the combination of adagrasib and olaparib to assess their joint efficacy and safety. This trial is in its early stages, focusing primarily on safety and determining the right doses. Research on each drug alone supports their safety, but the combination is being carefully monitored to ensure it is well-tolerated. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of Adagrasib and Olaparib for treating solid tumors because it targets cancer in two innovative ways. Adagrasib inhibits a specific mutant form of the KRAS protein, which is a common driver of cancer cell growth in many tumors, while Olaparib blocks PARP enzymes, crucial for cancer cell repair. This dual approach could potentially halt tumor growth more effectively than current treatments that typically target only one pathway. By leveraging these two mechanisms, this combination aims to improve patient outcomes and offer a new hope for those with challenging solid tumors.

What evidence suggests that this trial's treatments could be effective for advanced solid tumors?

Research has shown that combining the drugs adagrasib and olaparib, which participants in this trial will receive, may help treat advanced solid tumors with certain genetic mutations. One study found that this combination increased the tumor shrinkage rate to 46% and extended the time patients lived without cancer worsening to 6.9 months for colorectal cancer, compared to using adagrasib alone. Adagrasib has proven effective in patients with KRAS G12C mutations. Patients also tolerated this combination treatment well, suggesting it could be a promising option for those with these types of tumors. ^{1 2 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Adagrasib
• Olaparib

Trial Overview

The trial is testing a combination of two drugs: Adagrasib and Olaparib for patients with certain genetic mutations in their tumors. The goal is to find the safest dose level. Participants will receive both medications and be monitored for how well they tolerate them and any signs of tumor response.

How Is the Trial Designed?

Group I: Adagrasib+Olaparib Experimental Treatment 2 Interventions

Participants will take adagrasib and olaparib by mouth 2 times each day. Each dose should be taken at about 12 hours apart (1 dose in the morning, 1 dose in the evening). The study drugs should be swallowed whole with water. Do not chew, crush, dissolve, or divide the study drugs. If forget a dose and less than 2 hours have passed since the usual time participants take the study drug, take the dose as soon as participants remember. If more than 2 hours have passed, do not take the dose. Wait and take the next dose as scheduled

Adagrasib is already approved in United States, European Union for the following indications:

Approved in United States as Krazati for:

• KRAS G12C-mutated locally advanced or metastatic non-small cell lung cancer (NSCLC)
• KRAS G12C-mutated locally advanced or metastatic colorectal cancer

Approved in European Union as Krazati for:

• KRAS G12C mutation non-small cell lung cancer

Published Research Related to This Trial

Niraparib has been approved by the FDA for patients with complete or partial response to first-line platinum-based chemotherapy, regardless of their BRCAm or HRD status, expanding treatment options for more patients.

Olaparib, in combination with bevacizumab, has also received FDA approval for patients with epithelial ovarian cancer, indicating that PARP inhibitors are now beneficial not only for BRCAm and HRD-deficient patients but also for those with HRD-proficient tumors.
