Brief 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.
Detailed Description:
PRIMARY OBJECTIVE:
I. To determine if the combination of berzosertib (M6620) with topotecan hydrochloride (topotecan) will result in an improvement in progression-free survival (PFS) compared to topotecan alone in patients with relapsed small cell lung cancer (SCLC).
SECONDARY OBJECTIVE:
I. To determine the objective response rate (ORR) and overall survival (OS) with the combination of M6220 and topotecan in patients with relapsed SCLC and extrapulmonary small cell cancers.
EXPLORATORY OBJECTIVES:
I. To perform molecular profiling assays on malignant and normal tissues, including, but not limited to ribonucleic acid (RNA) sequencing (RNA-Seq):
Ia. To assess expression of genes Schlafen family member 11 (SLFN11), MYC, and ataxia-telangiectasia mutated (ATM) among others.
Ib. To identify potential predictive biomarkers of response to a combination of M6620 with topotecan.
Ic. Identify mechanisms of drug sensitivity and resistance using deoxyribonucleic acid (DNA)- and RNA-based assessment platforms.
II. To contribute genetic analysis data from de-identified biospecimens to Genomic Data Commons (GDC), a well annotated cancer molecular and clinical data repository, for current and future research; specimens will be annotated with key clinical data, including presentation, diagnosis, staging, summary treatment, and if possible, outcome.
III. To bank formalin-fixed, paraffin-embedded (FFPE) tissue, blood (for cell-free DNA analysis), and nucleic acids obtained from patients at the Early-Phase and Experimental Clinical Trials (EET) Biobank at Nationwide Children's Hospital.
IV. To characterize circulating cell-free DNA (cfDNA) and circulating tumor cells in patients with relapsed SCLC and extrapulmonary small cell cancers.
V. To identify potential predictive biomarkers of response to a combination of M6620 with topotecan in patients with extrapulmonary small cell cancers.
OUTLINE: Patients are assigned to 1 of 2 cohorts.
COHORT I: Patients with SCLC are randomized to 1 of 2 arms.
ARM I: Participants receive topotecan hydrochloride intravenously (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 computed tomography (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.
ARM II: Participants receive topotecan hydrochloride IV over 30 minutes on days 1-5 and berzosertib (M6620) IV over 60 minutes on days 2 and 5. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. 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.
COHORT II (Patients with extrapulmonary small cell cancer): Participants receive topotecan hydrochloride IV over 30 minutes on days 1-5 and berzosertib (M6620) IV over 60 minutes on days 2 and 5. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. 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.
After completion of study treatment, patients are followed up at 4 weeks and then every 12 weeks thereafter.
