136P - Long-term safety and efficacy of darbepoetin alfa in subjects with stage IV NSCLC receiving multi-cycle chemotherapy (ID 357)
12:30 - 13:00 | Author(s): M. Šmakal
Darbepoetin alfa (DA) is an erythropoiesis-stimulating agent (ESA) that has been shown to increase hemoglobin levels and reduce the rate of transfusions in patients with chemotherapy-induced anemia (CIA). Most studies have not shown an association between ESA use and poor outcomes, but some clinical trials have reported increased mortality and/or tumor progression. This trial was therefore designed to address the safety of DA for CIA in patients with non-small cell lung cancer (NSCLC).
Study 20070782 is a randomized, double-blind, noninferiority trial to compare DA with placebo, and is enrolling patients with NSCLC with CIA. Eligible patients are ≥ 18 years old with Eastern Cooperative Oncology Group (ECOG) status ≤ 1, stage IV NSCLC, no prior adjuvant/neoadjuvant NSCLC therapy, ≥ 2 cycles first-line chemotherapy planned (≥ 6 weeks total), and screening hemoglobin ≤ 11 g/dL. Approximately 3,000 patients from up to 500 global sites will be randomized 2:1 to DA (500 mcg) or placebo every 3 weeks (Q3W) until disease progression or end of chemotherapy. At hemoglobin > 12 g/dL, study drug is withheld until hemoglobin ≤ 12 g/dL. Transfusions are allowed when necessary. Endpoints include overall survival (OS; primary) and progression-free survival (PFS; secondary), and will be analyzed when ∼2,700 deaths have occurred. Additional safety endpoints include tumor response and rate of thromboembolic events. Superiority of DA to placebo in transfusion rates will be tested if noninferiority is achieved for OS and PFS.
As of January 1, 2017, a total of 2,447 patients have enrolled. The independent data monitoring committee has conducted 10 reviews of unblinded data (which included a planned formal interim analysis at 60% of planned total number of 2,700 deaths to test for harm), and has recommended continuation of the trial without changes.
Study 20070782 is the largest clinical trial in NSCLC to date, and will provide comprehensive data on the safety and efficacy of DA in patients with CIA.
