Summary

This trial is researching a potential new cancer treatment to see how safe and effective it is.

Who is the study for?
This trial is for adults with advanced solid tumors like lung, stomach, or breast cancer that's worsened after standard treatments. Participants must have evidence of oncogene amplification and measurable disease. They should be in good physical condition (ECOG PS 0 or 1) and have proper organ function. People with primary brain cancers, certain heart conditions, active hepatitis B/C or HIV, a history of severe lung issues, or those who've had specific transplants can't join.
What is being tested?
The study tests BBI-355 as a new treatment targeting ecDNA in tumors. It's an early-phase trial to find the safest dose when given alone or with other therapies. The drug is taken orally and aims to inhibit CHK1—a protein involved in tumor cell growth.
What are the potential side effects?
As this is a first-in-human study for BBI-355, detailed side effects are not yet known but may include typical reactions related to checkpoint inhibitors such as fatigue, nausea, blood count changes and potential liver or kidney function alterations.
