Randomized Phase II Trial of Topotecan Plus M6620 (VX-970, Berzosertib) Vs. Topotecan Alone in Patients With Relapsed Small-Cell Lung Cancer

National Cancer Institute (NCI)·interventional·Posted Apr 1, 2019·Updated Jun 29, 2026

In Brief

A Phase 2 clinical trial evaluating Berzosertib, Biopsy Procedure, and 3 other interventions for Extensive Stage Lung Small Cell Carcinoma and 5 related conditions. Active but no longer recruiting, targeting 104 participants across 33 sites.

Detailed Summary

This phase II trial studies how well berzosertib (M6620) works when given in combination with topotecan hydrochloride (topotecan) compared with topotecan alone in treating patients with small cell lung cancer that has come back (relapsed), or small cell cancer that arises from a site other than the lung (extrapulmonary). Drugs used in chemotherapy, such as topotecan hydrochloride, work by damaging the DNA (deoxyribonucleic acid) in tumor cells, causing those cells to die and the tumor to shrink. However, some tumor cells can become less affected by chemotherapy because they have ways to repair the damaged DNA. The addition of M6620 could help topotecan hydrochloride shrink the cancer and prevent it from returning by blocking enzymes needed for DNA repair.

Arms & Interventions

Cohort I Arm I (topotecan hydrochloride)active_comparator

Participants receive topotecan hydrochloride IV over 30 minutes on days 1-5. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Participants may crossover to Arm II at disease progression. Participants undergo a CT scan during screening and on study as well as a tumor biopsy during screening. Participants may also undergo blood sample collection during screening and on study.
