This phase II study involved advanced non-small-cell lung cancer patients who had not received prior chemotherapy. Patients were divided into two separate treatment groups. Group A consisted of 420 patients with a median age of 62 years and 65% male. Group B had 408 patients with a median age of 61 years and 66% male.

Patients in group A were treated with the chemotherapy agents paclitaxel and carboplatin.

Patients in group B were treated with paclitaxel and carboplatin, as well as the immunotherapy agent called PF-3512676, which triggers a protein called TLR9 to stimulate an antitumor immune response.

Treatment-related deaths due to infection were reported for group A. Grade 3 or higher neutropenia, leukopenia, lymphopenia, and thrombocytopenia were also reported.

Treatment-related deaths were reported for group B; causes included pulmonary embolism and infection. Grade 3 or higher injection-site reactions, such as pain and swelling, were also reported.

The median overall survival rates for groups A and B were 9.8 and 10.0 months, respectively.

This study was supported by Pfizer, Inc.
