BioMimetic Therapeutics, Inc. (NASDAQ: BMTI) today announced it initiated enrollment in a Phase II clinical trial to assess the safety and efficacy of Augment™ Chronic Tendinopathy (ACT) as a treatment for lateral epicondylitis, commonly known as tennis elbow. The randomized, controlled trial is expected to enroll up to 100 patients at seven clinical sites in the U.S. and will evaluate the safety and therapeutic potential of escalating doses of a one-time injection of pure recombinant human platelet-derived growth factor (rhPDGF-BB) homodimer solution into the extensor carpi radialis brevis (ECRB), the tendon in the elbow that is generally the source of pain in tennis elbow. The product candidate is aimed at the large tendinosis market for which there is significant unmet clinical need with limited effective long-term treatments currently available.
“We have seen promising pre-clinical data with ACT and believe the initiation of this Phase II dose finding clinical trial is the logical next step in the development of our sports medicine program,” said Dr. Samuel Lynch, BioMimetic president and CEO. “ACT has the potential to help millions of patients suffering from painful inflammation of the tendon at the outer border of the elbow resulting from overuse of lower arm muscles or trauma.”
The Phase II trial is designed as a randomized, ascending dose, double-blinded, placebo controlled, multi-center study. The trial is expected to enroll up to 100 patients ranging from 21 – 80 years of age, who will receive a single injection into the ECRB. The injection will consist of either a placebo or one of four different doses of rhPDGF-BB.The primary efficacy endpoints will be derived from a combination of pain and disability assessments as measured by the Visual Analog Scale (VAS), Disabilities of the Arm, Shoulder and Hand (DASH) Score and the Patient Rated Tennis Elbow Evaluation (PRTEE), along with sincerity of effort measured by grip strength testing. These clinical outcome measures will be used to detect changes in pain and function up to 24 weeks from baseline. Adverse event reporting, including incidence, relationship with treatment and severity will be recorded throughout the study to evaluate safety of the drug. The product candidate will be reviewed by the U.S. Food and Drug Administration’s (FDA) Center for Drug Evaluation and Research (CDER), which regulates over-the-counter and prescription drugs, including biological therapeutics and generic drugs.
