Experimental combo for tough lung cancer shows early promise, but study halted

NCT ID NCT06016270

First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This early-phase trial tested an experimental antibody called hSTC810 combined with the chemotherapy drug paclitaxel in 10 adults with relapsed or refractory extensive-stage small cell lung cancer. The goal was to see if the combination is safe and helps shrink tumors or slow the cancer's growth. However, the study was terminated early, so we have very limited information about how well it worked.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

hSTC810 (an experimental antibody) combined with paclitaxel (a chemotherapy drug)

What this could lead to

If successful, this combination could offer a new treatment option for people with relapsed small cell lung cancer, potentially slowing disease progression.

What could go wrong

The trial was terminated early with only 10 participants, so results are very limited. It is unclear if the combination is safe or effective, and side effects from chemotherapy are common.
