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.

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.

Eligibility

Yes No Not Sure

Inclusion Criteria

Age≥ 18 years
Histologically or cytologically confirmed ES-SCLC (per the Veterans Administration Lung Study Group (VALG) staging system)
No prior treatment for ES-SCLC
Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
Patients with a history of treated, asymptomatic CNS metastases are eligible providing they meet the following criteria
Only supratentorial and cerebellar metastases allowed (i.e., no metastases to midbrain, pons, medulla or spinal cord)
No ongoing requirement for corticosteroids as therapy for CNS disease
No stereotactic brain radiation within 7 days
No evidence of interim progression between the completion of CNS-directed therapy and the screening radiographic study
Patients with new asymptomatic Central Nervous System (CNS) metastases detected at the screening scan must receive radiation therapy and/or surgery for CNS metastases. Following treatment, these patients may then be eligible without the need for an additional brain scan prior to randomization, if all other criteria are met
At least one liver metastasis measuring 1 cm
Measurable disease, as defined by RECIST v1.1, in addition to the liver lesion(s) to which SBRT is planned
Patients must submit a pre-treatment tumor tissue sample from a liver metastasis. Tumor tissue must be obtained prior to the start of treatment
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
Aspartate aminotransferase (AST), Alanine Aminotransferase (ALT), and alkaline phosphatase ≤5×ULN
Serum bilirubin ≤1.25×ULN (Patients with known Gilbert disease who have serum bilirubin level ≤3×ULN may be enrolled)
Serum creatinine ≤1.5×ULN
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. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not adequate methods of contraception
For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use
a condom, and agreement to refrain from donating sperm, as defined below
With female partners of childbearing potential or pregnant female partners, men must remain abstinent or use a condom during treatment with chemotherapy (i.e., carboplatin and etoposide) and for at least 6 months after the last dose of chemotherapy to avoid exposing the embryo
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. Periodic abstinence and withdrawal are not acceptable methods of contraception
Negative HIV test at screening, with the following exception: patients with a positive
HIV test at screening are eligible, provided they are stable on anti-
retroviral therapy, have a CD4 count3 200/µL, and have an undetectable viral
load
Ability to understand and the willingness to sign a written informed consent document
Ability to comply with the study protocol, in the investigator's judgment

Exclusion Criteria

Active or untreated CNS metastases as determined by computed tomography (CT) or magnetic resonance imaging (MRI) evaluation during screening and prior radiographic assessments
Spinal cord compression not definitively treated with surgery and/or radiation or previously diagnosed and treated spinal cord compression without evidence that disease has been clinically stable for ≥1 week prior to randomization
Leptomeningeal disease
Prior radiation treatment of SCLC outside of the CNS
Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures (once monthly or more frequently). Patients with indwelling catheters (e.g., PleurX®) are allowed
Uncontrolled or symptomatic hypercalcemia (>1.5 mmol/L ionized calcium or calcium >12 mg/dL or corrected serum calcium >ULN)
Patients who are receiving denosumab prior to randomization must be willing and eligible to discontinue its use and replace it with a bisphosphonate while in the study
Malignancies other than SCLC within 5 years prior to randomization, with the exception of those with a negligible risk of metastasis or death (e.g., expected 5-year OS >90%) treated with expected curative outcome (such as adequately treated carcinoma in situ of the cervix, basal or squamous-cell skin cancer, localized prostate cancer treated surgically with curative intent, ductal carcinoma in situ treated surgically with curative intent)
Prior radiation for non-SCLC malignancies >5 years prior to randomization will be permitted, with the exception of those who underwent liver-directed treatments

History of liver-directed ablative therapy for any indication, including radiation, chemoembolization, radiofrequency ablation, or other similar modalities
Women who are pregnant, lactating, or intending to become pregnant during the study
Pregnant women are excluded from this study because carboplatin and etoposide are category D agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with atezolizumab, breastfeeding should be discontinued if the mother is treated with atezolizumab
