NCT ID NCT06150664

First seen Jan 05, 2026 · Last updated Jun 22, 2026 · Updated 16 times

Summary

This early-stage study is testing an experimental drug called CTX-8371 in people with advanced lung, breast, lymphoma, head and neck, or skin cancers that have not responded to standard treatments. The main goal is to check the drug's safety and find the best dose. About 85 participants will receive the drug by IV every two weeks. Because this is a first-in-human trial, it is too early to know if the drug will shrink tumors or improve survival.

What this could mean

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

Active substance

CTX-8371 (an experimental drug given by IV infusion every two weeks)

What this could lead to

If this drug is safe and shows signs of shrinking tumors, it could lead to a new treatment option for people with advanced cancers that have stopped responding to standard therapies.

What could go wrong

This is a very early Phase 1 trial with only 85 participants, so the main goal is safety, not effectiveness. The drug may not work or could cause serious side effects, and it will take years before it might become available.

Conditions

The condition(s) this trial relates to.

Hodgkins lymphoma melanoma non-small cell lung carcinoma Squamous Cell Carcinoma of Head and Neck triple-negative breast carcinoma
