The Company plans to begin a Phase 3 study in the second quarter in collaboration with the Friedreich's
"This is a significant step forward in the further development of ACTIMMUNE beyond the approved indications of chronic granulomatous disease and severe, malignant osteopetrosis," said
The Phase 3 study is expected to be a randomized, double-blind, multicenter, placebo-controlled, 26-week study evaluating ACTIMMUNE in approximately 90 male and non-pregnant female subjects between the ages of 10 and 25 years, inclusive, with an FA functional stage of greater than 1 to less than 5 and the ability to walk 25 feet with or without an assistive device. Subjects will be randomized 1:1 to receive either ACTIMMUNE or matching placebo. The primary endpoint will be the change in the Friedreich's Ataxia Rating Scale-modified neurological exam score (FARS-mNeuro), which is a measure of disease activity and correlates significantly with functional disability, from baseline to 26 weeks for patients treated with ACTIMMUNE compared to placebo. It is anticipated that it will take 18 months to completely enroll the study. A six-month open-label extension study will be offered to those FA patients completing the Phase 3 study.
"We are greatly encouraged by the collaborative efforts of the
About Friedreich's Ataxia (FA)

ACTIMMUNE (interferon gamma-1b) is a biologically manufactured protein similar to one the body makes naturally to help prevent infection. ACTIMMUNE is currently approved by the
IMPORTANT SAFETY INFORMATION
APPROVED USES FOR ACTIMMUNE (interferon gamma 1-b)
Chronic Granulomatous Disease (CGD)
ACTIMMUNE is indicated to reduce the frequency and severity of serious infections associated with Chronic Granulomatous Disease. CGD is a genetic disorder that affects the functioning of some cells of the immune system.
Severe, Malignant Osteopetrosis (SMO)
ACTIMMUNE is indicated to slow the worsening of severe, malignant osteopetrosis. SMO is a genetic disorder that affects normal bone formation.
IMPORTANT SAFETY INFORMATION (ISI)
The most common side effects with ACTIMMUNE are "flu-like" symptoms such as fever, headache, chills, myalgia (muscle pain) or fatigue, which may decrease in severity as treatment continues. Bedtime administration of ACTIMMUNE may minimize some of these symptoms. Acetaminophen may be helpful in preventing fever and headache.
If you are pregnant or plan to become pregnant or plan to nurse you should consult your physician.
ACTIMMUNE can cause severe allergic reactions and/or rash. Do not use ACTIMMUNE if you are allergic to interferon-gamma, E. coli-derived products or any component of the product (See Full Prescribing Information for a list of components). If you develop a serious reaction to ACTIMMUNE, discontinue it immediately and contact your doctor or seek medical help.
At high doses, ACTIMMUNE can cause (flu-like) symptoms, which may worsen some pre-existing heart conditions. Tell your doctor if you have a cardiac condition, such as irregular heartbeat, heart failure or decreased blood flow to your heart.
ACTIMMUNE may cause reversible changes to your nervous system, including decreased mental status, walking disturbances and dizziness. Tell your doctor if you have a history of seizures or other neurologic disorders.
Bone marrow function may be suppressed with ACTIMMUNE and decreased production of cells important to the body may occur. This effect, which can be severe, is usually reversible when the drug is discontinued or the dose is reduced. Tell your doctor if you have, or have had, reduced bone marrow function. Your doctor will monitor these cells with blood tests at the beginning of therapy and at 3 month intervals thereafter.
Taking ACTIMMUNE may cause reversible changes to your liver function, particularly in patients less than one year old. Your doctor will monitor your liver function with blood tests at the beginning of therapy and at 3 month intervals. If the patient is 1 year or less, monitoring will be done on a monthly basis.
If you are receiving ACTIMMUNE at home, your doctor will provide to you or your caregiver appropriate instructions on the administration of the drug and disposal of the container, needles and syringes.
You are encouraged to report negative side effects of prescription drugs to the
