Summary

This is trial studying the safety of adaptive stereotactic body radiotherapy (SBRT) combined with durvalumab immunotherapy, platinum chemotherapy, and etoposide chemotherapy in platinum refractory extensive stage small cell lung cancer (SCLC).

Conditions

  • Extensive-stage Small-cell Lung Cancer

Interventions

DRUG

Durvalumab 50 MG/1 ML Intravenous Solution

Durvalumab (1500 mg durvalumab via IV infusion) in combination with platinum doublet chemotherapy will be administered to patients once every 3 weeks for up to 4 cycles plus SBRT (platinum resistant group) or without SBRT (platinum sensitive group). Each 3-week of chemoimmunotherapy interval is considered a cycle. Patients with platinum sensitive disease will receive the combination of durvalumab and chemotherapy (total of four cycles) while those with platinum resistant SCLC will receive SBRT and continue to receive up to two additional cycles of treatment with durvalumab along with platinum/etoposide (not to exceed a total of four6 cycles of chemoimmunotherapy including 2 cycles obtained prior to SBRT). Following completion of 4-6 cycles of combination therapy, patients in both groups will continue with maintenance durvalumab (1500 mg) in q4w cycles until disease progression.

DRUG

Etoposide Injection

A platinum/etoposide doublet will be administered according to institutional standards. Platinum-etoposide will consist of etoposide 80-100 mg/m2 on days 1-3 of each cycle along with a choice of either carboplatin area under the curve 5-6 mg/mL per min or cisplatin 75-80 mg/m2 (administered on day 1 of each cycle).

DRUG

Cisplatin

A platinum/etoposide doublet will be administered according to institutional standards. Platinum-etoposide will consist of etoposide 80-100 mg/m2 on days 1-3 of each cycle along with a choice of either carboplatin area under the curve 5-6 mg/mL per min or cisplatin 75-80 mg/m2 (administered on day 1 of each cycle).

DRUG

Carboplatin

A platinum/etoposide doublet will be administered according to institutional standards. Platinum-etoposide will consist of etoposide 80-100 mg/m2 on days 1-3 of each cycle along with a choice of either carboplatin area under the curve 5-6 mg/mL per min or cisplatin 75-80 mg/m2 (administered on day 1 of each cycle).

DEVICE

Stereotactic Body Radiotherapy

Patients will receive palliative radiation to the primary tumor site up to 30 Gy for 1 week given as 5 daily fractions of 6 Gy each or 27 Gy as 3 fractions of 9 Gy administered every other day.
