Brief Summary:
This phase II/III trial compares the effect of immunotherapy with atezolizumab in combination with standard chemotherapy with a platinum drug (cisplatin or carboplatin) and etoposide versus standard therapy alone for the treatment of poorly differentiated extrapulmonary (originated outside the lung) neuroendocrine cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). The other aim of this trial is to compare using atezolizumab just at the beginning of treatment versus continuing it beyond the initial treatment. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cisplatin and carboplatin are in a class of medications known as platinum-containing compounds that work by killing, stopping or slowing the growth of cancer cells. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair, and it may kill cancer cells. Giving atezolizumab in combination with a platinum drug (cisplatin or carboplatin) and etoposide may work better in treating patients with poorly differentiated extrapulmonary neuroendocrine cancer compared to standard therapy with a platinum drug (cisplatin or carboplatin) and etoposide alone.

Primary Outcome Measures :
- Overall survival [ Time Frame: From date of registration or from date of start of observation/maintenance therapy to date of death due to any cause, assessed up to 5 years ]Log-rank tests stratified by the randomization stratification factors will be used for null hypothesis (efficacy) tests. Cox regression models stratified by the randomization stratification factors will be used for alternative hypothesis (futility) tests.
Secondary Outcome Measures :
- Progression-free survival [ Time Frame: From date of registration or start of observation/maintenance therapy to date of first documentation of progression or symptomatic deterioration, or death due to any cause, assessed up to 5 years ]Will be estimated using the Kaplan-Meier method and compared using log-rank tests.
- Duration of response [ Time Frame: Time from date of initial response to date of progression or death, assessed up to 5 years ]Will be estimated non-parametrically using cumulative incidence curves.
- Objective response rate (confirmed complete response [CR] and partial response [PR]) [ Time Frame: Up to 5 years from study enrollment ]Will be tabulated and compared between arms using Fisher's exact test.
- Clinical benefit rate (confirmed CR or PR of any amount of time or stable disease for 6 months or longer) [ Time Frame: Up to 5 years from study enrollment ]Will be tabulated and compared between arms using Fisher's exact test.
