Cerulean Pharma Inc. Presents Phase 2a Clinical Data at American Association for Cancer Research (AACR) 102nd Annual Meeting 2011

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Apr 4, 2011 - Cerulean Pharma Inc., a leader in designing and developing tumor-targeted nanopharmaceuticals, today announced that the Company will present data from the ongoing Phase 2a study of its lead clinical development candidate, CRLX101, at the AACR 102nd Annual Meeting 2011, ongoing in Orlando, Florida.

Dr. Glen J. Weiss, M.D., of TGen Clinical Research Services in Scottsdale, Arizona, a principal investigator of the study, will present a poster containing interim data from the ongoing MTD-expansion study of CRLX101. The study has been fully enrolled. To date, 13 patients are continuing on therapy. In this poster presentation, the data will show that the recommended Phase 2 dose and schedule is well tolerated. Furthermore, the poster also includes preliminary clinical activity data that highlight observations of stable disease in advanced non-small cell lung carcinoma (NSCLC) patients. Specifically, the interim data show that 70% of the NSCLC patients achieved stable disease of greater than or equal to 3 months, and 20% of them achieved stable disease of greater than or equal to 6 months. Eight of the 13 patients continuing on therapy are NSCLC patients.

“We are very encouraged by these data from the Phase 2a study of CRLX101, an innovative nanopharmaceutical that may have significant advantages over current therapies for advanced NSCLC,” said Oliver Fetzer, Ph.D., Chief Executive Officer of Cerulean. “The prolonged progression-free disease observed with CRLX101 in patients who had advanced progressive disease on prior therapies is very encouraging, particularly when one considers that current 2nd line NSCLC therapies provide a median progression-free survival period of only 3 months. Furthermore, the Phase 2a patients on the study are maintaining good quality of life.”

The fully-enrolled study is ongoing at City of Hope National Medical Center, in Duarte, California, TGen Clinical Research Services in Scottsdale, Arizona, and San Juan Oncology Associates in Farmington, New Mexico. Complete results from this study will be presented later this year.

Cerulean plans to begin enrollment of a randomized Phase 2 study of CRLX101 in patients with advanced NSCLC in Eastern Europe in the second quarter of 2011. The study is designed to assess efficacy of CRLX101 as a single agent compared to best supportive care in advanced NSCLC with overall survival as the primary endpoint. The study will enroll patients who have failed one or two previous regimens.
