S095035 for Advanced Cancer

This trial tests a new treatment called S095035, sometimes combined with TNG462, to evaluate its effectiveness against advanced solid tumors. It targets individuals whose tumors have a specific genetic change (a homozygous deletion of MTAP) and who have not responded to standard treatments. The trial includes various cancer types, such as non-small cell lung cancer, biliary tract cancer, pancreatic cancer, and gastroesophageal cancer. Candidates with a confirmed MTAP gene deletion and cancer progression after previous treatments may be suitable participants. 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.

The trial does not specify if you need to stop taking your current medications. However, you must not have received any systemic anticancer treatment or radiotherapy within 2 weeks before starting the trial.

Research shows that S095035, whether used alone or with TNG462, is still undergoing safety testing in humans. S095035 blocks an enzyme called MAT2A, linked to tumor growth, while TNG462 targets another enzyme, PRMT5, also involved in tumor cells.

Studies have shown that oral cancer drugs like S095035 have undergone safety checks. Some studies suggest that serious side effects can occur, though they are uncommon. As this is the first human trial for this treatment, researchers are closely monitoring for any side effects.

Researchers are excited about S095035 because it introduces a potential game-changer for advanced cancers like Non-Small Cell Lung Cancer, Biliary Tract Cancer, and Pancreatic Ductal Adenocarcinoma. Unlike standard treatments that often involve chemotherapy or radiation, S095035 focuses on unique mechanisms, possibly offering a more targeted approach with fewer side effects. Additionally, the combination of S095035 with TNG462 in some treatment arms suggests a novel strategy to enhance efficacy by attacking cancer cells through multiple pathways. This innovative approach could lead to improved outcomes for patients who have limited options with existing therapies.

Research has shown that S095035 is designed to block an enzyme called MAT2A. This blockage indirectly stops another enzyme, PRMT5, potentially leading to the death of tumor cells. In this trial, participants with pancreatic ductal adenocarcinoma (PDAC) may receive S095035 as a single-agent treatment, which has shown promise in killing cancer cells. Other participants may receive a combination of S095035 with TNG462, which directly blocks PRMT5. Early findings suggest that this combination could be especially helpful for biliary tract cancer (BTC) and gastroesophageal cancers, showing positive results in studies with cancers missing the MTAP gene. These insights provide hope for treating advanced cancers with limited options.¹³⁴⁵⁶
