Summary

This trial is testing a new cancer drug to see if it is safe and works well against breast cancer cells.

Who is the study for?
Adults with metastatic breast cancer, specifically triple-negative type that's worsened after standard treatments. Participants must have acceptable organ function and blood counts, not be pregnant or breastfeeding, agree to use contraception, and can't have certain infections or uncontrolled high blood pressure.
What is being tested?
The trial is testing PMD-026, an oral medication aimed at destroying tumor cells in patients with advanced breast cancer. It examines the drug's safety and how well patients tolerate it. The study involves two parts: dose escalation to find a safe dosage and dose expansion to test its effects further.
What are the potential side effects?
While specific side effects of PMD-026 are not listed here, common ones for cancer drugs include nausea, fatigue, diarrhea, risk of infection due to low blood cell counts, liver issues (elevated enzymes), kidney problems (changes in creatinine levels), and potential heart complications.
