Penwest Announces Initiation of Phase IIa Clinical Trial of A0001 in Patients With Friedreich's Ataxia


PATTERSON, N.Y., Jan. 11, 2010 (GLOBE NEWSWIRE) -- Penwest Pharmaceuticals Co. (Nasdaq:PPCO) today announced that it initiated a Phase IIa clinical trial for A0001 in December and that the screening of patients is underway. The study is being conducted at The Children's Hospital of Philadelphia in patients with Friedreich's Ataxia (FA).

The primary objective of this study is to investigate whether treatment with A0001 has a discernible impact on various functional, biochemical and subject/clinician-rated scales relevant in the treatment of FA. The Phase IIa clinical trial is a double-blind, randomized, placebo-controlled trial that includes a high and low dose of A0001 and a placebo. Penwest plans to enroll approximately 42 patients with a 2:1 randomization of drug to placebo. The patients will be dosed for 28 days. The Company expects data from this trial in the third quarter of this year.

The Friedreich's Ataxia Research Alliance (FARA) is helping to enroll patients for this study by utilizing its patient registry. Ronald J. Bartek, FARA's President and Co-Founder, said, "The Friedreich's ataxia community is excited that A0001 is ready to be dosed in our patients. We believe the science behind the molecule is very interesting and that A0001 could be an important therapy for FA patients. FARA has been helping support the development of A0001 for a number of years and is continuing to assist its development partners at Penwest by working with the patient community to ensure the trial enrolls rapidly."

Jennifer L. Good, Penwest's President and CEO, said, "We are very pleased to be advancing A0001 into a proof of concept trial in patients. There is a significant unmet medical need in Friedreich's ataxia and we are hopeful that A0001 can provide an important treatment option for these patients."

About A0001

A0001, or alpha-tocopherol quinone, is a coenzyme Q10 analog demonstrated to improve mitochondrial function in-vitro. Penwest believes that impairment of mitochondrial function is a key component of the diseases that it plans to target with A0001, and that enhancing mitochondrial function may provide substantial clinical benefit to patients. The Company exclusively licensed A0001 from Edison Pharmaceuticals, a privately-held biopharmaceutical company headquartered in San Jose, CA.

About Friedreich's Ataxia

Friedreich's Ataxia (FA) is a debilitating, life-shortening, degenerative neuro-muscular disorder. About one in 50,000 people in the United States have FA. Onset of symptoms can vary from childhood to adulthood. FA patients have gene mutations that limit the production of a protein called frataxin. Frataxin is known to be an important protein that functions in the mitochondria (the energy producing factories) of the cell. Frataxin helps to move iron and is involved with the formation of iron-sulfur clusters, which are necessary components in the function of the mitochondria and thus energy production. It is also known that specific nerve cells (neurons) degenerate in people with FA, and this is directly manifested in the symptoms of the disease.

The signs and symptoms of FA include: loss of coordination (ataxia) in the arms and legs, fatigue, energy deprivation, muscle loss, vision impairment, hearing loss, slurred speech, aggressive scoliosis (curvature of the spine), diabetes mellitus, and a serious heart condition (enlarged heart - hypertrophic cardiomyopathy).
