New drug cocktail aims to shrink Hard-to-Treat solid tumors
NCT ID NCT07140393
First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study tests a new drug called HRS-4508 in combination with other cancer treatments (such as capecitabine, trastuzumab, and pertuzumab) for people with advanced solid tumors that cannot be removed by surgery or have spread. The goal is to find the best dose, check safety, and see if the combination helps shrink tumors. About 120 adults aged 18 to 75 with measurable tumors and good overall health are eligible to participate.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- HRS-4508
- What this could lead to
- If successful, this could provide a new combination treatment option for people with advanced solid tumors that are not responding to standard therapies.
- What could go wrong
- This is an early-phase trial with a small number of participants, so the drug may not prove effective or could cause unexpected side effects. Results may not apply to all solid tumor types.
