Early trial of experimental cancer combo halted after just 6 patients
NCT ID NCT06870487
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase study tested a new drug called PF-08046032, given alone or with another drug (sasanlimab), in adults with advanced lymphomas or solid tumors like lung cancer and melanoma. The trial aimed to check safety and find the right dose, but it was terminated early after enrolling only 6 participants. Because it was stopped, we have very limited information on how well it works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PF-08046032 (a new drug given by IV) and sasanlimab (an immunotherapy given as a shot)
- What this could lead to
- If it works, this could point toward a new treatment option for certain advanced cancers that have not responded to standard therapies.
- What could go wrong
- This was a very early Phase 1 trial with only 6 participants and was terminated early, so results are limited. The drug may not prove safe or effective in larger studies.
