Cancer drug T-DXd safety tracked in ongoing rollover study
NCT ID NCT06174987
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study offers continued access to the cancer drug T-DXd for up to 50 people with advanced or metastatic cancer who are already benefiting from it in earlier trials. Researchers will monitor long-term safety, including serious side effects and reasons for stopping or reducing the drug. The goal is to ensure the treatment remains safe over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- T-DXd (trastuzumab deruxtecan)
- What this could lead to
- If successful, this study could confirm that long-term use of T-DXd is safe for people with advanced cancer, supporting its continued use as a treatment option.
- What could go wrong
- This is a small, open-label rollover study (50 participants) focused on safety, not on proving effectiveness. It may not detect rare side effects or apply to all patients.
