Phase I/IIa Study of the Novel Combination of Bendamustine With Irinotecan Followed by Etoposide/Carboplatin in Chemonaive Patients With Extensive Stage Small Cell Lung Cancer
In Brief
A Phase 2 clinical trial evaluating Novel Drug Combination for Small Cell Lung Cancer and 2 related conditions. Completed, enrolled 30 participants across 2 sites.
Detailed Summary
Small cell lung cancer, or SCLC, constitutes approximately 15% of the 170,000 new cases of lung cancer diagnosed annually in the United States. Extensive-stage SCLC comprises two thirds of new cases and is generally considered sensitive to chemotherapy, despite a median time to progression of 4 months. SCLC is one of the most aggressive and lethal types of cancer, with a median survival of 9 months (range 7-11 months) in patients diagnosed with extensive disease. Overall, the majority of patients with SCLC die in less than 2 years (2-year survival rates generally less than 10%), and the 5-year survival rate is 2.3% for patients with extensive disease. The regimen of etoposide in combination with a platinum (cisplatin or carboplatin) is generally considered the "standard of care" although a recent Phase III trial suggests improved survival with the combination of cisplatin/irinotecan. Further evaluation of new agents in combination regimens attempting to overcome the intrinsic drug resistance seen in extensive-stage SCLC is warranted attempting to improve survival and achieve palliation of disease-related symptoms.

Interventions
This novel drug combination includes: Bendamustine, Irinotecan, and Etoposide/Carboplatin. Subjects will be treated with irinotecan (150 mg/m2) infusion on Day 1 followed by infusion of bendamustine on Days 1 and 2 at increasing dose levels using a 3+3 design (starting dose of 80-mg/m2/d with 20 mg/mg/d incremental increase to max 120 mg/m2/d) (Regimen A). This will be repeated every 3 weeks for a total of 3 cycles. Restaging for response will be performed prior to the next regimen. * All subjects will then be given carboplatin (AUC 6) on day 1 and etoposide (100 mg/m2) on days 1, 2 and 3 (Regimen B). They will receive 3 cycles of this regimen every 3 weeks prior to restaging. * At the end (3 weeks after) of the sixth total round of chemotherapy, subjects will be re-evaluated for response, and will be followed-up for recurrent disease every 8 weeks.
