New cancer pill shows early promise, but trial halted
NCT ID NCT03114319
First seen Jun 27, 2026 · Last updated Jul 10, 2026 · Updated 2 times
Summary
This early-stage trial tested an oral drug called TNO155, alone or with another drug (nazartinib), in 227 adults with advanced solid tumors like lung cancer, melanoma, and head/neck cancer. The main goal was to check safety and find the right dose. The study was terminated early, so results are limited and no clear benefit has been shown yet.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- TNO155 (a SHP2 inhibitor) taken orally, alone or with nazartinib
- What this could lead to
- If successful, this could point toward a new treatment option for certain advanced cancers like lung or skin cancer.
- What could go wrong
- This was a very early (Phase 1) trial that was terminated, so it's unclear if the drug is safe or effective. Many early cancer drugs fail to show benefit.

Patients must be screened for Hepatitis B virus and Hepatitis C virus Exclusion Criteria: 1. Tumors harboring known activating KRAS, NRAS, HRAS, BRAF or PTPN11 (SHP2) mutations.
