Randomized phase II evaluation of aprinocarsen in combination with gemcitabine and cisplatin for patients with advanced/metastatic non-small cell lung cancer.
Aprinocarsen is a specific antisense oligonucleotide inhibitor of protein kinase C-alpha. This study aimed to evaluate the response rate to combination therapy with aprinocarsen, gemcitabine and cisplatin, in chemonaive patients with advanced/metastatic NSCLC. Secondary objectives included comparison of response rate, time to event efficacy parameters, and toxicities on the 2 treatment arms. Patients with stage IV, or stage IIIB disease (N3 and/or pleural/pericardial effusion), were randomized to either control or experimental arm. Patients on both arms received gemcitabine 1250 mg/m2 on days 1 and 8, and cisplatin 80 mg/m2 on day 1 of a 3-week cycle. Additionally, on the experimental arm, aprinocarsen was administered as 2 mg/kg continuous iv infusion on days 1-14, every 21 days. A total of 18 enrolled patients were randomized on the 2 arms. Further enrollment was terminated in March 2003 as a result of a phase III trial suggesting that aprinocarsen did not have an added survival benefit when combined with paclitaxel and carboplatin therapy in patients with NSCLC. Patients received a median of 4 cycles on control arm and 2.5 cycles on experimental arm. The response rate was 16.7% in the experimental arm and 44.4% in the control arm. Most frequent grade 3/4 toxicities were hematologic, with a higher incidence of thrombocytopenia in the experimental arm (87.5% vs. 33.3%). Despite the 14-day continuous infusion schedule, infection rate was not increased in the experimental arm. The present study did not show any advantage, in response rate or secondary endpoints, with aprinocarsen; however, the toxicity was not unduly increased, and aprinocarsen regimen was safely administered.
