Summary

This trial is testing a new drug called PRT3789, which breaks down a protein in cancer cells, alone and with another drug, docetaxel. Docetaxel is a potent antitumor agent used in treating various cancers. It targets patients with advanced cancers that have lost a specific gene. The drug works by destroying a protein that helps cancer cells grow, potentially stopping the cancer from spreading.

Who is the study for?
This trial is for adults with advanced or metastatic solid tumors that have a specific genetic change called SMARCA4 mutation. They should be in fairly good health (ECOG 0 or 1), have tried other treatments without success, and can provide a tumor sample. People with certain other cancers, heart issues, uncontrolled electrolyte disorders, or brain metastases cannot join.
What is being tested?
PRT3789 is being tested to see how safe it is and what dose works best for treating these tumors. It's an early-phase study where researchers will slowly increase the dose to find the highest amount patients can take without serious side effects.
What are the potential side effects?
Since PRT3789 is new and this trial aims to discover its safety profile, potential side effects are not fully known yet. However, participants may experience typical drug-related reactions like fatigue, nausea, allergic responses or more serious conditions depending on their individual reaction.

Other Research
Common treatments for Non-Small Cell Lung Cancer (NSCLC) include chemotherapy, immune checkpoint inhibitors, and targeted therapies. Chemotherapy, such as docetaxel, works by killing rapidly dividing cancer cells. Immune checkpoint inhibitors, like nivolumab and pembrolizumab, enhance the immune system's ability to recognize and destroy cancer cells by blocking proteins that inhibit immune responses. Targeted therapies, including SMARCA2 degraders like PRT3789, focus on specific genetic mutations or proteins involved in cancer cell growth and survival. These treatments are crucial for NSCLC patients as they offer personalized and potentially more effective options, especially for those with specific genetic profiles or who have failed first-line treatments.
