Brief Summary

Small cell lung cancer (SCLC) is a rapidly proliferating, neuroendocrine tumor that accounts for about 15% of all lung cancers. Most patients have metastases at primary diagnosis involving sites like bone, adrenal glands, liver and brain. Compared with non-small-cell lung cancer (NSCLC) SCLC has a unique natural history with a shorter doubling time, higher growth fraction, earlier development of widespread metastases, and uniform initial response to chemo- or radiotherapy. The combination of cis- or carboplatin and etoposide is the standard of care in the first-line treatment of stage IV (extensive-disease) SCLC (ED-SCLC). Despite response rates of 50-80%, most patients relapse within six months and the median survival time is less than 10 months. Between 14 and 23% of SCLC patients develop brain metastases. New cytotoxic agents as well as targeted therapies have not been able to show any improvement of survival in this group of patients. Early phase trials of PD 1/PD L1-blocking immunotherapeutic agents in patients with recurrent or ED SCLC have shown promising response rates and good tolerability. Immunotherapy may also contribute to the efficacy of systemic treatment by maintaining initial responses to chemotherapy. A double-blind, placebo-controlled phase 3 trial indicates that the addition of atezolizumab to standard chemotherapy significantly improves overall survival and progression-free survival compared with chemotherapy alone in treatment-naïve patients with ED-SCLC who are in good general condition (ECOG 0 or 1). However, about one in three SCLC patients has a poor performance status (ECOG≥2), which is associated with even shorter survival times of under eight months. At present, there is little information regarding the feasibility, safety and efficacy of adding atezolizumab to standard chemotherapy for this considerable fraction of patients. The investigators expect, that atezolizumab in addition to chemotherapy is feasible in patients with stage IV SCLC and reduced performance status and therefore crucial efficacy data can be acquired in this trial to evaluate a putative Phase III transition in this particular patient population.

Outcome Measures

Primary Outcomes (1)

  • Overall survival (OS)

    OS is defined as the length of time from first dose of experimental IMP (or first dose of chemotherapy, whichever occurs first) to the date of death. A subject who has not died will be censored at last known date alive.

    Measured from first dose of experimental IMP (or first dose of chemotherapy, whichever occurs first) through study completion, an average of one year.

Secondary Outcomes (5)

  • Objective response rate (ORR) (RECIST 1.1)

    Starting from Screening up to an average of one year.

  • Progression-free suvival (PFS)

    Starting from Screening up to an average of one year.

  • Incidence of Treatment-Emergent adverse events, serious adverse events and laboratory abnormalities leading to treatment discontinuation

    Starting from Screening up to an average of one year.

  • Quality of life (EORTC-QLQ-C30)

    Starting from Screening up to an average of one year.

  • Quality of life (PRO-CTCAE)

    Starting from Screening up to an average of one year.

Study Arms (1)

Atezolizumab

EXPERIMENTAL

Four 21-day cycles of induction therapy with atezolizumab+carboplatin+etoposide followed by 21-day cycles of maintenance therapy with atezolizumab.

Drug: Atezolizumab

Interventions

1200 mg i.v. on day 1 of each cycle

Atezolizumab

Eligibility Criteria

  • ECOG 2
  • At least one measurable tumor lesion (according to RECIST1.1)
  • Histologically confirmed small cell lung cancer (SCLC)
  • Stage IV disease (according to UICC8)
  • No active autoimmune disease
  • Adequate organ function defined as:
  • neutrophil count \> 1.5 x 109/L
  • thrombocytes ≥ 100 x 109/L
  • hemoglobin ≥ 9 g/dL
  • INR ≤ 1.4 or aPTT ≤ 40 sec during the last 7 days before therapy \[Subjects under therapeutic anticoagulation are permitted.\]
