Company Received $5.2 Million in Cost Recovery from EAP in 2007

RICHMOND, Va., Jan. 24 /PRNewswire-FirstCall/ -- Insmed Inc. (Nasdaq: INSM), a developer of follow-on biologics and biopharmaceuticals, today provided an update on the IPLEX(TM) Expanded Access Program (EAP) in Italy for the treatment of Amyotrophic Lateral Sclerosis (ALS). Since early 2007, the EAP has grown to include 15 physicians and approximately 70 subjects have been enrolled into the program. Additional subjects continue to be enrolled into the program. IPLEX(TM) appears to have been safe and well tolerated in the subject population to date and no individuals have dropped out of the study for reasons related to IPLEX(TM). The Company received cost recovery of $5.2 million for drug supplies for the full-year 2007.

The study utilizes a Revised ALS Functional Rating Scale (ALSFRS) to monitor the progress of the subjects. The ALSFRS is used to determine a patient's capacity and independence in several functional activities including speech, salivation, swallowing, handwriting, cutting foods and handling utensils, dressing and hygiene, turning in bed, walking, climbing stairs, and respiratory function. The purpose of collecting this information is to help ensure safety and to gain an understanding as to whether IPLEX(TM) provides any benefit to these subjects.

ALS, often referred to as Lou Gehrig's disease, is a progressive neurodegenerative disorder that affects nerve cells in the brain and spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle movement action progressively negatively affected, those patients in the later stage of the disease may become totally paralyzed. The ALS Associati
