Study 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.

Primary Outcome

The combination of M6620 with topotecan will be compared to topotecan alone in participants with relapsed small cell lung cancer (SCLC). Kaplan-Meier curves and a one-tailed log-rank test will be the primary analysis methods. PFS is defined as the duration of time from start of treatment to time of progression or death. whichever occurs first. Progression was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1) and is at least a 20% increase in the sum of
