SG and Immunotherapy as Maintenance Therapy for Extensive-stage Small-cell Lung Cancer

Summary

The goal of this clinical trial is to learn if the combination of sacituzumab govetican (SG) and atezolizumab/durvalumab is effective in controlling cancer tumor growth in adults with extensive stage small cell lung cancer. These drugs are FDA approved individually in different cancers. This combination is evaluated in breast cancer and showed promising combination. The effectiveness of this treatment combination will be measured by changes in tumor size and appearance of new tumors. Participants in the trial will: * receive treatment SG and immunotherapy every 21 days for up to 2 years or until it is no longer works for the patient. * CT scans at 6weeks for first 6 cycles and then every 9-12 weeks and MRI brain every 12 weeks. * provide tissue (optional) and blood for additional testing (learn about the cancer).

Eligibility

Inclusion Criteria:

* Participant is willing and able to give informed consent for participation in the trial.
* Male or Female aged 18 years or above.
* Participants must have a histologically or cytologically confirmed diagnosis of small cell lung cancer (SCLC) and extensive stage at diagnosis or locally advanced disease and unable to receive curative intent radiation.
* Participants must have received at least four cycles of platinum plus etoposide and at least 2-3 cycles of atezolizumab/ Durvalumab.
* No evidence of progression on restaging CT CAP following 4-6 cycles of Chemo/IO from the last dose of the chemotherapy cycle.

* Participants with leptomeningeal disease.
* Participants with a recent diagnosis of heart failure and acute coronary disease within 3 months.
* Participants who are unable to receive immunotherapy with chemotherapy for induction will be excluded, or those immunotherapy was discontinued to manage immune-related adverse events
* Active chronic inflammatory bowel disease (ulcerative colitis, Crohn's disease) or gastrointestinal perforation within 6 months of enrolment.
* Patients with prior exposure to anti-PD-1, anti-PD-L1, or anti-PD-L2 agents or with an agent directed to another stimulatory or coinhibitory T-cell receptor (eg, CTLA-4) within 12 months of the study is not allowed.
