What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a combination of two treatments, lifirafenib and mirdametinib, for individuals with advanced or spreading tumors. The goal is to determine the optimal dose and assess how effectively these medicines work together against cancer. The trial specifically targets tumors with an NRAS mutation, a gene change that can influence cancer growth. Individuals with advanced tumors that cannot be surgically removed and have not responded to other treatments may be suitable candidates. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment combination.

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications, including chemotherapy, immunotherapy, biologic therapy, hormonal, or molecular targeted therapy within 2 weeks before starting the study. You also cannot take certain other medications like strong CYP3A inhibitors or systemic glucocorticoid therapy within 2 weeks before the trial.

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications, including chemotherapy, immunotherapy, biologic therapy, hormonal, or molecular targeted therapy within 2 weeks before starting the trial. Additionally, you cannot take systemic or glucocorticoid therapy within 2 weeks or medicines that are strong CYP3A inhibitors.

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

Research has shown that the combination of lifirafenib and mirdametinib is generally safe. Previous studies found that many patients tolerated the treatment well, with few experiencing severe side effects. This suggests the combination is relatively safe for people, although further research is needed to confirm this. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about Lifirafenib and Mirdametinib for treating NRAS-mutated solid tumors because these drugs target specific pathways often involved in cancer growth. Unlike traditional chemotherapy that attacks rapidly dividing cells indiscriminately, Lifirafenib specifically inhibits BRAF mutations, while Mirdametinib targets the MEK1/2 pathway. This targeted approach could potentially result in fewer side effects and more effective treatment outcomes. By combining these two drugs, the treatment aims to tackle cancer growth from multiple angles, offering hope for improved responses in patients with these genetic mutations.

What evidence suggests that this trial's treatments could be effective for cancer?

This trial will investigate the combination of lifirafenib and mirdametinib for cancer treatment. Research has shown that this combination can help fight tumors in patients with specific genetic changes in their cancer, such as KRAS, NRAS, and BRAF mutations. Lifirafenib blocks certain proteins that aid cancer cell growth, while mirdametinib targets other pathways involved in cancer progression. Early studies indicate that this combination is generally safe and typically does not cause severe side effects. Although still under investigation, these findings suggest the treatment could be effective for certain solid tumors with these mutations. ^{1 2 3 6 7}

Published Research Related to This Trial

Lifirafenib, a new drug targeting B-RAF and other kinases, was found to be safe and tolerable at a maximum dose of 40 mg/day, with common side effects including hypertension and fatigue.

The drug showed promising antitumor activity in patients with B-RAF mutations, achieving complete and partial responses in various solid tumors, while also demonstrating efficacy in some K-RAS-mutated cancers.

Vemurafenib is associated with a higher incidence of acute kidney injury compared to dabrafenib, with 132 reported cases during the study period, particularly affecting male patients.

Both drugs can cause electrolyte imbalances, such as hypokalemia and hyponatremia, indicating the importance of monitoring renal function and electrolyte levels in patients undergoing treatment.

This phase I/II clinical trial is investigating the safety and efficacy of a combination treatment involving selumetinib, tremelimumab, and durvalumab in 40 patients with previously treated, unresectable non-small-cell lung cancer (NSCLC).

The study aims to determine the maximum tolerated dose and progression-free survival, while also exploring biomarkers of response and resistance, which could help tailor future treatments for NSCLC patients.

In a subgroup of 109 patients with EGFR-mutant NSCLC from the MARQUEE study, the combination of erlotinib and tivantinib significantly improved progression-free survival, with a median of 13.0 months compared to 7.5 months for erlotinib alone.

The combination therapy also showed a trend towards improved overall survival, with a median of 25.5 months for erlotinib plus tivantinib versus 20.3 months for erlotinib plus placebo, although the results were not statistically significant.

The combination of tivantinib and sorafenib was found to be safe and tolerable in 87 patients with advanced solid tumors, with the most common side effects being rash, diarrhea, and anorexia, but no unexpected toxicities were reported.

Preliminary results showed a 12% overall response rate, with higher efficacy in specific cancers: 26% in melanoma, 15% in renal cell carcinoma, and 10% in hepatocellular carcinoma, indicating potential therapeutic benefits for these tumor types.

In a phase I trial, BGB-283 was shown to be safe and well-tolerated in patients with solid tumors that have mutations in BRAF, KRAS, and NRAS.

The trial demonstrated that BGB-283 is effective in treating these tumors, indicating its potential as a targeted therapy for specific genetic mutations.

The combination of sorafenib and gefitinib is well tolerated in patients with advanced non-small cell lung cancer, with most side effects being mild (grade 1/2), although some patients experienced more severe effects like diarrhea and elevated liver enzymes.

Out of 31 patients treated, 65% achieved stable disease for at least 4 months, indicating promising efficacy, while the recommended dose for further studies was established as sorafenib 400 mg twice daily with gefitinib 250 mg once daily.

In a study of 43 patients with BRAF V600-mutant metastatic colorectal cancer, the combination of dabrafenib and trametinib showed activity, with 12% of patients achieving a partial response and one patient achieving a complete response lasting over 36 months.

All patients evaluated during treatment showed a significant reduction in phosphorylated ERK levels, indicating effective inhibition of the mitogen-activated protein kinase signaling pathway, although the response was less pronounced than in BRAF-mutant melanoma.

The maximum tolerated doses (MTDs) for the combination of pembrolizumab and trametinib were established, with concurrent dosing showing a lower objective response rate (0%) compared to intermittent dosing (27%).

While the combination treatment had manageable safety profiles, with 31% of patients experiencing grade 3/4 treatment-related adverse events in the concurrent group, the overall antitumor activity was limited, suggesting that this combination may not be highly effective for solid tumors and BRAF wild-type melanoma.
