Acceleron Announces Presentations on ACE-083 at the 23rd International Annual Congress of the World Muscle Society

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Sep. 27, 2018-- Acceleron Pharma Inc. (Nasdaq:XLRN), a leading biopharmaceutical company in the discovery and development of TGF-beta therapeutics to treat serious and rare diseases, today announced plans to deliver poster presentations on ACE-083 from Part 1 of each its ongoing Phase 2 trials in patients with facioscapulohumeral muscular dystrophy (FSHD) and Charcot-Marie-Tooth disease (CMT) at the 23rd International Annual Congress of the World Muscle Society to be held in Mendoza, Argentina, October 2-6, 2018.

Presentations

Title:  

Results for a dose-escalation phase 2 study to evaluate ACE-083, a local muscle therapeutic, in patients with facioscapulohumeral muscular dystrophy (Poster: P.365)

Session: Poster Session 4 - FSHD/OPMD/EDMD/DMI
Date: Friday, October 5, 2018
Time: 5:00 - 6:30 p.m. ART (Hotel Intercontinental Mendoza, Poster area)
 
Title:

Preliminary phase 2 results for ACE-083, local muscle therapeutic, in patients with CMT1 and CMTX (Poster: P.339)

Session: Poster Session 4 - CMT and neurogenic disease
Date: Friday, October 5, 2018
Time: 5:00 - 6:30 p.m. ART (Hotel Intercontinental Mendoza, Poster area)

“As we’ve reported at neurology congresses throughout this year, patients with FSHD and CMT treated with ACE-083 in these studies have experienced robust mean increases exceeding 12% in total and contractile muscle volume,” said Robert K. Zeldin, M.D., Chief Medical Officer of Acceleron. “We’re now pleased to be able to share these results at this important global muscle meeting as we enroll patients in Part 2 of these Phase 2 trials to evaluate ACE-083’s potential to improve functional outcomes in both disorders.”

The ACE-083 clinical presentations will be available in the “Science” section on Acceleron’s website, www.acceleronpharma.com, on the opening day of the conference.

ACE-083 is currently being evaluated in two Phase 2 trials: one in FSHD and one in CMT. Preliminary results from Part 2 of the trials are expected in the second half of 2019 for FSHD and by year end 2019 for CMT.

About ACE-083

ACE-083, a locally-acting therapeutic candidate based on the naturally-occurring protein follistatin, utilizes the Myostatin+ approach to inhibit multiple TGF-beta ligands. It is designed to have a concentrated effect along targeted muscles to maximize growth and strength selectively in the muscles into which the drug is administered. Acceleron is developing ACE-083 for disorders such as CMT and FSHD, in which improved muscle strength in target muscles may provide a clinical benefit and enhance quality of life.

About FSHD

FSHD is a rare genetic muscle disorder affecting approximately 20,000 people in the United States for which there are currently no approved treatments. The primary clinical presentation of FSHD is debilitating skeletal muscle weakness and loss. The symptoms of FSHD develop in a descending pattern, beginning with the face and upper body and progressing to the lower body in a "muscle by muscle" fashion. The disease is typically diagnosed by a characteristic pattern of muscle weakness and other clinical symptoms, as well as through genetic testing.

About CMT

CMT is one of the most common inherited neurologic diseases, estimated to affect more than 125,000 people in the United States. The primary clinical manifestations of CMT include muscle weakness in the lower legs and arms. The lower leg muscle weakness can result in foot drop leading to a high-stepped gait and frequent tripping or falls. The disease is typically diagnosed by the presence of a characteristic pattern of muscle weakness, nerve conduction studies, and genetic testing. There are no FDA approved drug therapies for CMT.
