Summary

This trial tests nirogacestat, a medication that blocks a protein involved in tumor growth, on patients with desmoid tumors. These tumors are rare and can cause serious health issues. The drug aims to stop a chain reaction that helps these tumors grow. Nirogacestat has shown antitumor activity in several tumor types.

Who is the study for?
This trial is for adults with a type of tumor called desmoid tumor/aggressive fibromatosis (DT/AF) that has grown by at least 20% in the past year. Candidates must have finished any previous treatments for DT/AF at least 28 days before starting the study and resolved all treatment side effects to mild levels. They should be able to perform daily activities with slight limitations or better, as assessed by their ECOG performance status.
What is being tested?
The trial is testing nirogacestat, an oral tablet, against a placebo (a pill without active medication). Participants are randomly assigned to one of these two groups in a double-blind phase where neither they nor the researchers know who's receiving which treatment. After this phase, all participants will receive nirogacestat during an open-label phase.
What are the potential side effects?
While specific side effects for nirogacestat aren't listed here, common types of side effects from medications like it may include digestive issues, fatigue, skin reactions, changes in liver function tests and potentially increased risk of infections.

Other Research
Nirogacestat, a Gamma-Secretase Inhibitor, works by blocking the gamma-secretase enzyme, which plays a key role in the Notch signaling pathway involved in cell differentiation and proliferation. This inhibition can help reduce the growth and spread of aggressive fibromatosis tumors. For patients, this targeted approach offers a promising treatment option that may be more effective and have fewer side effects compared to traditional therapies.
