Trial Outcomes & Findings for Liver Directed RT + Chemo-immunotherapy for ES-SCLC (NCT NCT04923776)

NCT ID: NCT04923776

Last Updated: 2024-12-30

Results Overview

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.

Participant milestones

Participant milestones
Measure
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. 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. 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. Atezolizumab: The dosage for this drug is 1200 mg Intravenous, Day 1, every 21 days until disease progression. This is standard of care. 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

Timeframe: Up to 6 months

Population: Data was not analyzed or disclosed in an effort to protect participant confidentiality (n=1).

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.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 2 years

Population: Data was not analyzed or disclosed in an effort to protect participant confidentiality (n=1).

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.

SECONDARY outcome

Timeframe: Up to 2 years

Population: Data was not analyzed or disclosed in an effort to protect participant confidentiality (n=1).

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.
