Interventions

Lurbinectedin — DRUG
Participants meeting inclusion and exclusion criteria will receive lurbinectedin (on day 1) and berzosertib (on day 1 and 2) administered every 21 days (1 cycle), either in the in-patient or out-patient setting, until disease progression or development of intolerable side effects.
Berzosertib — DRUG

Study Details

Background: Small cell lung cancer (SCLC) and high-grade neuroendocrine cancers (HGNEC) are aggressive neuroendocrine cancers. At first, SCLC and HGNEC respond to chemotherapy. But then they relapse quickly and become resistant to treatment. Researchers want to see if a combination of drugs can help. Objective: To see if the combination of lurbinectedin and berzosertib may be effective to shrink SCLC and HGNEC tumors, and to find the best dose of the combination. Eligibility: Adults ages 18 and older with a solid tumor, SCLC, or HGNEC. Design: Participants will get lurbinectedin by intravenous (IV) catheter on Day 1 of each cycle (1 cycle = 21 days). They will get berzosertib by IV on Days 1 and 2 of each cycle. Participants will continue to receive treatment as long as they are benefiting from treatment. Participants will have physical exams and blood tests. Their symptoms, medicines, and ability to perform their normal activities will be reviewed. Participants will have electrocardiograms to test heart function. Sticky pads will be placed on their chest, arms, and legs. Participants will give blood and hair samples for research. They may have optional tumor biopsies. Participants will have computed tomography (CT) scans to see if the treatment is effective. Participants will have a follow-up visit 1 month after treatment ends. Then they will be followed by email or phone for the rest of their life.
