This study has 2 cohorts: MOZART-ES cohort (for extensive-stage SCLC) and MOZART-LS cohort (for limited-stage SCLC).
MOZART-ES cohort: Study treatment will consist of a platinum drug (carboplatin or cisplatin per investigator's choice) plus etoposide plus durvalumab plus monalizumab every 3 weeks for 4 cycles. After 4 cycles, subjects will continue maintenance treatment with durvalumab plus monalizumab every 4 weeks until disease progression, unacceptable toxicity, decision to stop study treatment, or withdrawal of consent. Patients who have received one prior cycle of treatment before enrolling on the study will receive a total of 4 cycles with monalizumab, durvalumab, and chemotherapy. There will be a safety lead-in phase, including 6 to 12 patients, to confirm the safety of the proposed dose of monalizumab to use in combination with chemotherapy and durvalumab.
MOZART-LS cohort: Study treatment will consist of durvalumab and monalizumab following standard of care chemo-radiation consisting of a platinum drug (carboplatin or cisplatin per investigator's choice) plus etoposide for 3-4 cycles and standard dose radiation. Radiation therapy should have started before completion of cycle 2 of chemotherapy. NOTE: Subjects who have non-progressive disease and meet the eligibility criteria can start study treatment up to 56 days from completion of chemo-radiation. Durvalumab and monalizumab will be administered every 4 weeks for up to 2 years (26 cycles), disease progression, unacceptable toxicity, decision to stop study treatment, or withdrawal consent, whichever occurs first.
