Evaluating Sutetinib for Advanced Lung Cancer

A Multicenter, Open-label, Phase IIb Study to Evaluate the Efficacy and Safety of Sutetinib Maleate Capsule in Locally Advanced or Metastatic NSCLC (Non-resistant Uncommon EGFR Mutations Only, Including L861Q, G719X, and/or S768I)

PHASE2 · Teligene US · NCT05168566

This study is testing if a new drug called Sutetinib can help people with advanced lung cancer that has certain rare mutations feel better and improve their treatment outcomes.

What this trial studies

This Phase 2b multicenter, open-label study aims to assess the safety and efficacy of Sutetinib Maleate Capsule in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) harboring specific non-resistant uncommon EGFR mutations. The study will involve patients who have had limited prior chemotherapy and will evaluate the drug's effectiveness in inhibiting cancer cell growth associated with these mutations. Participants will receive Sutetinib and be monitored for treatment outcomes and side effects.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with locally advanced or metastatic NSCLC and specific non-resistant uncommon EGFR mutations.

Not a fit: Patients who have previously received EGFR-TKI therapy or have other types of EGFR mutations may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with specific EGFR mutations in lung cancer.

How similar studies have performed: Other studies have shown promise with similar EGFR-targeted therapies, indicating potential for success with this approach.
