Brief Summary:
The purpose of this study is to evaluate whether radiation treatment directed at liver metastases can be safely added to standard of care treatment for extensive stage small cell lung cancer (ES-SCLC). The current standard treatment for people who have ES-SCLC is chemotherapy including drugs called carboplatin and etoposide, that is combined with a type of immunotherapy called atezolizumab. However, patients with liver involvement of their ES-SCLC don't respond as well to this treatment. The study aims to answer whether adding radiation directed at liver metastases can improve responses to standard chemo-immunotherapy in this patient population. All study participants will get the same study intervention, which will be chemo-immunotherapy and radiation therapy.

Condition or disease Intervention/treatment Phase
Small-cell Lung Cancer Drug: Carboplatin Drug: Etoposide Drug: Atezolizumab Radiation: Stereotactic Body Radiation Therapy (SBRT) Phase 2

Detailed Description:

Although the clinical evidence for the combination of radiation therapy and immunotherapy is more limited, numerous case reports, retrospective studies, early stage trials, and ongoing prospective trials highlight the potential for combining radiation with immunotherapy in augmenting the anti-tumor response.

The combination of stereotactic body radiation therapy (SBRT) of liver lesions with immunotherapy has been less well studied. Given the findings that patients with ES-SCLC and liver involvement have a poor prognosis and a limited response to chemo-immunotherapy, the investigators aim to augment the systemic anti-tumor immune response with RT targeted to liver metastases administered in addition to standard of care treatment. Preclinical data and prior clinical studies support the reasoning for these treatment approaches, and the investigators hypothesize that combination RT with chemo-immunotherapy will lead to improved local control and progression free survival in ES-SCLC patients with liver involvement.

Arm Intervention/treatment
Experimental: Experimental: Chemotherapy+SBRT

Addition of SBRT, directed at liver metastases, to standard of care (SOC) treatment atezolizumab+chemotherapy in SCLC. All patients must undergo a mandatory biopsy of a liver lesion prior to chemotherapy initiation.

Cycle 1 of chemoimmunotherapy will be administered as per standard of care, with radiation planning to be done subsequently in anticipation of liver-directed SBRT.

Drug: Carboplatin
The dosage for this drug is area under the curve (AUC) 5 mg/ml/min intravenous, Day 1, every 21 days for 4 cycles. This is standard of care.
Other Name: Paraplatin

Drug: Etoposide
The dosage for this drug is 100 mg/m2 Intravenous, Days 1-3, every 21 days for 4 cycles. This is standard of care.
Other Name: Vepesid

Drug: Atezolizumab
The dosage for this drug is 1200 mg Intravenous, Day 1, every 21 days until disease progression. This is standard of care.
Other Name: Tecentriq

Radiation: Stereotactic Body Radiation Therapy (SBRT)
This radiotherapy is given within +/-3 days of cycle 2, 10 Gy 3 doses on alternating days. This is not standard of care and considered interventional.

Primary Outcome Measures :
  1. Progression Free Survival (PFS) Rate [ Time Frame: Up to 6 months ]
    Progression free survival rate at 6 months will be measured to assess the efficacy of liver-directed SBRT when added to standard of care atezolizumab + chemotherapy. 6-month PFS rate will be defined as the proportion of patients that are progression free and alive at 6 months from the start of treatment.

Secondary Outcome Measures :
  1. Overall Survival Rate [ Time Frame: Up to 2 years ]
    Overall survival (OS) will be defined as the time from treatment start to date of death or last follow up. Patients lost to follow-up at the cut-off date will be censored in the analysis.

  2. Disease control rate (DCR) [ Time Frame: Up to 2 years ]
    Disease control rate (DCR) will be defined as the proportion of patients who have a partial (PR) or complete response (CR) or stable disease (SD) after beginning study treatment. Only patients who have received at least one cycle of therapy and have had their disease re-evaluated will be considered evaluable for response.

  9. Adequate hematologic and end organ function, defined by the following laboratory results:

    • Absolute neutrophil count (ANC) ≥1500 cells/μL without granulocyte colony-stimulating factor support
    • Lymphocyte count ≥500/μL
    • Platelet count ≥100,000/μL without transfusion
    • Hemoglobin ≥9.0 g/dL Patients may be transfused to meet this criterion.
    • International Normalized Ratio (INR) or Activated Partial Thromboplastin Time (aPTT) ≤1.5×upper limit of normal (ULN) This applies only to patients who are not receiving therapeutic anticoagulation; patients receiving therapeutic anticoagulation should be on a stable dose.

  10. For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods as defined below:

    • Women must remain abstinent or use contraceptive methods with a failure rate of < 1% per year during the treatment period and for 6 months after the final dose of carboplatin and etoposide
    • A woman is considered to be of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (≥12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). The definition of childbearing potential may be adapted for alignment with local guidelines or requirements.
    • Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices.
    • The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient.
