New hope for Hard-to-Treat nasopharyngeal cancer: targeted drug HLX43 enters phase 2 trial

NCT ID NCT06839066

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tests HLX43, a drug that targets a protein called PD-L1 on cancer cells and delivers a toxin to kill them. It is for people with recurrent or metastatic nasopharyngeal carcinoma who have failed or cannot tolerate second-line therapy. About 70 participants will receive one of three doses to find the best balance of safety and effectiveness.

What this could mean

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

Active substance

HLX43 (an antibody-drug conjugate that targets PD-L1 and delivers a chemotherapy-like toxin to cancer cells)

What this could lead to

If successful, this could offer a new treatment option for people with advanced nasopharyngeal cancer who have run out of standard therapies.

What could go wrong

This is a small, early-phase trial (70 people) testing different doses, so it may not show strong enough benefit or could have unexpected side effects. The drug is still experimental.
