NCT04919382

Brief Summary

This phase II trial studies the effects of temozolomide and atezolizumab as second or third line treatment for patients with small cell lung cancer that has spread to other places in the body (metastatic) or has come back (recurrent). Chemotherapy drugs, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. 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. Giving temozolomide and atezolizumab as second or third line treatment may help prolong survival in patients with small cell lung cancer.

Outcome Measures

Primary Outcomes (1)

  • Investigator-assessed objective response rate (ORR)

    Assessed by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Response will be defined by a confirmed complete response (CR) or confirmed partial response (PR). Response will be defined for patients with measurable disease and who receive at least one dose of combination treatment. ORR rate will be calculated as the proportion of patients with RECIST-based PR or CR divided by the total number of evaluable patients. Exact binomial 90% and 95% confidence intervals for the true PR+CR response rate will be calculated.

    Up to 2 years

Secondary Outcomes (4)

  • Treatment related adverse events

    Up to 2 years

  • Progression free survival (PFS)

    From initiation of investigational therapy until the criteria for disease progression is met as defined by RECIST1.1 or death as a result of any cause, assessed up to 2 years

  • Intracranial PFS

    At 6 months from start of investigational therapy

  • Overall survival

    Date of initiation of investigational therapy to date of death from any cause, assessed up to 2 years

Study Arms (2)

Cohort I (atezolizumab, temozolomide)

EXPERIMENTAL

Patients receive atezolizumab IV over 30-60 minutes on day 1 and temozolomide PO QD on days 1-5. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Biological: AtezolizumabDrug: Temozolomide

Cohort II (atezolizumab, temozolomide)

EXPERIMENTAL

Patients receive atezolizumab IV over 30-60 minutes on day 1. Patients also receive temozolomide PO QD on days 1-14 of cycle 1 and days 1-21 of subsequent cycles. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Biological: AtezolizumabDrug: Temozolomide

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization for release of personal health information
  • NOTE: HIPAA authorization may be included in the informed consent or obtained separately
  • Age \>= 18 years at the time of consent
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 2 within 28 days prior to registration
  • Have histologically or cytologically-documented diagnosis of extensive stage (i.e. metastatic and/or recurrent) small cell lung cancer and have progressed or recurred after platinum-based chemotherapy with immunotherapy. Eligible patients will be defined as follows:
