Icagen, Inc. Reports Third Quarter 2005 Financial Results

RESEARCH TRIANGLE PARK, N.C., Nov. 4 /PRNewswire-FirstCall/ -- Icagen, Inc. today reported financial results for the third quarter ended September 30, 2005. Revenues for the third quarter of 2005 totaled $2.3 million. Net loss for the third quarter of 2005 was $4.8 million. As of September 30, 2005, cash and cash equivalents totaled $52.2 million.

P. Kay Wagoner, Ph.D., CEO of Icagen, noted, “Icagen continued to make strong progress, particularly in our sickle cell disease program, during the third quarter of 2005. During the quarter, we continued patient and site enrollment in our pivotal Phase III trial of ICA-17043 for the chronic oral treatment of sickle cell disease. We now have the substantial majority of our clinical sites activated, and patient enrollment is progressing according to plan. In addition, we continue to prepare for the initiation of a pediatric safety and pharmacokinetics study in the first half of 2006, and a study in sickle cell disease patients with pulmonary hypertension in the second half of 2006. During the quarter, we also reported favorable results of our open label extension study to the Phase II clinical trial.”

Pipeline Update ICA-17043 for Sickle Cell Disease -- During the third quarter of 2005, the Company continued patient and site enrollment in its pivotal Phase III clinical trial of ICA-17043. ICA-17043 has both orphan drug designation and fast-track status. This trial is designed to be a randomized, double-blind, placebo-controlled study in 300 patients. The primary endpoint for this study is vaso- occlusive crisis rate in the ICA-17043 arm versus vaso-occlusive crisis rate in the placebo arm. The Company plans to conduct the study at approximately 65 sites across the U.S. and in selected other countries. The study design includes an interim analysis by an independent data monitoring committee. As of the end of the third quarter, approximately 55 sites had been initiated, including three international sites. The Company’s target timeframe for the completion of patient enrollment in the Phase III pivotal trial is the second half of 2006. -- The Company reported data from its open label extension study to the Phase II clinical trial of ICA-17043 during October 2005. -- The Company continues preparations for two additional clinical trials for ICA-17043 in the treatment of sickle cell disease. The first of these studies, expected to begin in the first half of 2006, will involve pediatric patients and will be primarily focused on the safety and pharmacokinetics of ICA-17043 in the pediatric population. The second of these studies, expected to begin in the second half of 2006, will involve sickle cell disease patients who have concomitant pulmonary hypertension, a common complication of this illness. Other Clinical and Preclinical Programs -- Development continued on the Company’s other clinical and preclinical programs, including the Company’s Phase I program in atrial fibrillation in collaboration with Bristol-Myers Squibb Company, the Company’s internal preclinical program in epilepsy and neuropathic pain, and the Company’s late-stage preclinical program in dementia, including Alzheimer’s disease, in collaboration with Astellas Pharma Inc., formerly Yamanouchi Pharmaceutical Co., Ltd.

Financials

Revenues for the third quarter of 2005 totaled $2.3 million, as compared to $1.8 million during the same period in 2004, an increase of 26%. The increase in revenues for the third quarter of 2005, as compared to the same period in 2004, was primarily due to increased cost sharing reimbursement from the Company’s collaboration with McNeil Consumer & Specialty Pharmaceuticals (“McNeil”) for the further clinical development of ICA-17043.

Operating expenses for the third quarter of 2005 were $7.5 million, as compared to $5.4 million for the same period in 2004, an increase of 39%. The increase in operating expenses for the third quarter of 2005, as compared to the same period in 2004, was primarily due to increased research and development expense related to the development of ICA-17043. In addition, general and administrative expense increased, primarily as a result of expenses associated with operating as a public company.

Net loss for the third quarter of 2005 was $4.8 million, as compared to $3.5 million for the same period in 2004, an increase of 37%, due primarily to higher research and development expenses and general and administrative expenses offset in part by an increase in revenues.

Revenues for the first nine months of 2005 totaled $6.1 million, as compared to $3.6 million during the same period in 2004, an increase of 70%. The increase in revenues for the first nine months of 2005, as compared to the same period in 2004, was primarily due to the initiation in June 2004 of the Company’s collaboration with McNeil for the further clinical development of ICA-17043.

Operating expenses for the first nine months of 2005 were $22.1 million, as compared to $15.9 million for the same period in 2004, an increase of 39%. The increase in operating expenses for the first nine months of 2005, as compared to the same period in 2004, was primarily due to increased research and development expense related to the development of ICA-17043 and the Company’s lead compounds for epilepsy and neuropathic pain. In addition, general and administrative expense increased, primarily as a result of expenses associated with operating as a public company.

Net loss for the first nine months of 2005 was $15.0 million, as compared to $12.2 million for the same period in 2004, an increase of 22%, due primarily to higher research and development expenses and general and administrative expenses, offset in part by an increase in revenues.
