About this trial
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).

Trial outcomes
Primary outcomes
Disease Control
To evaluate the rate of disease control at 12 weeks for patients with extensive stage small cell lung cancer treated with Sacituzumab govitecan (SG) plus atezolizumab or durvalumab as maintenance therapy after induction treatment with chemotherapy and immunotherapy. Disease Control at 12 weeks is defined as a best response by RECIST 1.1 of CR, PR, non-CR, non-PR, or stable disease assessed by RECIST 1.1 and reported within 12 weeks (+/- 2 weeks) from the initiation of study therapy. Participants not known to have disease control at 12 weeks will be coded as lacking disease control.
Secondary outcomes
Overall Survival
Overall Survival (OS): OS is defined as the duration from study registration to death due to any cause. Patients last known to be alive will be censored at the date of last contact.
Progression Free Survival
Progression-free survival (PFS): PFS is defined as the duration from study registration to progression, symptomatic deterioration, or death due to any cause. Patients last known to be alive and progression-free will be censored at the date of \[last contact or disease assessment\].
Combination therapy toxicity
To measure the frequency and severity of toxicity by incidence of treatment-emergent adverse events (TEAEs) and clinical laboratory abnormalities.
