What is the mechanism of action of this treatment?

Pembrolizumab, a PD-1 inhibitor, enhances the immune system's ability to detect and destroy cancer cells by blocking the PD-1 pathway, which tumors often exploit to evade immune detection. This is particularly important for solid tumor patients as it can lead to better tumor control and improved survival rates. Other treatments like chemotherapy target rapidly dividing cells, and targeted therapies focus on specific genetic mutations within the tumor, offering a more personalized approach to cancer treatment. Understanding these mechanisms allows for more effective and tailored treatment strategies for patients with solid tumors.

What side effects are associated with this type of intervention?

Common side effects of PD-1 inhibitors like Pembrolizumab in the treatment of solid tumors include fatigue, rash, pruritus, diarrhea, and nausea. Severe adverse events can include pneumonitis, colitis, hepatitis, endocrinopathies, and nephritis. For novel agents with unknown mechanisms, such as OMTX705, side effects can vary but often include similar immune-related adverse events, as well as potential infusion-related reactions and organ-specific toxicities. It is essential for patients to discuss these potential side effects with their healthcare provider to manage and mitigate risks effectively.

What prior FDA approvals exist?

Pembrolizumab, a PD-1 inhibitor, has received FDA approval for the treatment of various solid tumors, including non-small cell lung cancer (NSCLC), melanoma, and gastric cancer, among others. Other PD-1 inhibitors like Nivolumab have also been approved for similar indications. Additionally, combination therapies involving PD-1 inhibitors and other agents, such as chemotherapy or other immunotherapies, have been approved to enhance treatment efficacy. These approvals are based on clinical trials demonstrating improved overall survival and progression-free survival in patients with advanced or metastatic solid tumors.

What other types of research exist?

Promising alternatives to OMTX705 and pembrolizumab for solid tumors include: 1) Dostarlimab (Jemperli) for mismatch repair deficient (dMMR) recurrent or advanced endometrial cancer, 2) Lenvatinib plus pembrolizumab for advanced endometrial cancer with progression after platinum-based therapy, and 3) Enfortumab vedotin for advanced urothelial carcinoma after PD-1 or PD-L1 inhibitors. These treatments have shown efficacy in clinical trials and may be viable options in 2024.

Summary

This trial tests a new drug, OMTX705, alone or with pembrolizumab, in patients with advanced cancer who have no other treatment options. The study aims to find the safest dose and see if the combination works better than OMTX705 alone.

Who is the study for?

Adults with advanced or metastatic solid tumors without standard treatment options can join this trial. They must have measurable disease, good organ function, and an ECOG performance status of 0-1. Women who can bear children and men with partners who can must use contraception. Exclusions include active infections, certain heart conditions, pregnancy, recent other cancer treatments, uncontrolled brain metastases, and specific medication interactions.

What is being tested?

OMTX705 is being tested alone and combined with Pembrolizumab to treat advanced cancers in patients lacking other options. This Phase 1 study will gradually increase doses to find safe levels (dose-escalation) before expanding the number of participants at those levels (expansion phase).

What are the potential side effects?

Possible side effects may include reactions related to the immune system such as inflammation in various organs due to OMTX705 or Pembrolizumab's action on the body's defenses. Other common drug-related issues could be fatigue, digestive problems or changes in blood counts.
