Investigating a new treatment for advanced non-small cell lung cancer

A Phase 2, Open-label Study Evaluating STRO-002, an Anti-folate Receptor Alpha (FOLR1) Antibody-Drug Conjugate, in Subjects with Previously Treated Advanced or Metastatic Non-small Cell Lung Cancer Expressing FOLR1

Phase 2 Interventional Sutro Biopharma, Inc. · NCT06555263

This study is testing a new drug for adults with advanced lung cancer to see if it helps them feel better after other treatments haven't worked.

What this trial studies

This Phase 2 study evaluates the efficacy and safety of luveltamab tazevibulin, an antibody drug conjugate targeting FOLR1, in adults with previously treated advanced or metastatic non-small cell lung cancer (NSCLC). Participants will receive the treatment intravenously every three weeks until disease progression or intolerable side effects occur. The study aims to determine how well this drug works in patients whose cancer expresses the FOLR1 protein. It is a multicenter, open-label trial involving multiple locations in Florida and Minnesota.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with advanced or metastatic non-squamous NSCLC who have received 2 to 4 prior lines of systemic therapy.

Not a fit: Patients with untreated central nervous system metastases or those who have previously been treated with FOLR1-targeting therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced non-small cell lung cancer that expresses FOLR1.

How similar studies have performed: Other studies involving antibody drug conjugates have shown promise in treating various cancers, suggesting potential success for this approach.
