– Detailed Zydax Trial Results to be Presented Today at Company Investor Day –
Meeting to be Webcast Beginning at 8:30 AM ET
OVERLAND PARK, Kansas, June 18, 2015 (GLOBE NEWSWIRE) -- Parnell Pharmaceuticals Holdings Ltd (Nasdaq:PARN), a fully integrated pharmaceutical company focused on developing, manufacturing and commercializing innovative animal health solutions, today announced that Zydax, Parnell's osteoarthritis (OA) therapeutic being developed for dogs and horses, demonstrated a significant improvement in clinical signs of osteoarthritis in dogs in a pivotal clinical efficacy trial. In previous mechanism of action studies, Zydax has been shown to uniquely inhibit Aggrecanase-1, the enzyme understood to be the primary cause of degenerative joint disease and to stimulate proteoglycan synthesis necessary for cartilage regeneration.
"The results from our pivotal efficacy trial are exceptional in that Zydax demonstrated significant improvement across a spectrum of mobility assessments," said Robert Joseph, Chief Executive Officer of Parnell. "We believe Zydax presents a revolutionary opportunity for pet parents to improve the mobility of their best friends"
Key highlights of the trial results include:
- Using a validated measure for assessing changes in the clinical signs of osteoarthritis, Zydax treated dogs achieved significant improvements in mobility.
- Dog owners used the Client Specific Outcome Measures (CSOM) tool to quantify an Activity Impairment Score (AIS) to track changes in their dogs' mobility. At 14 days, Zydax treated dogs achieved an AIS reduction of 2 (20% improvement; p=0.04 vs. placebo) and at 28 days an AIS reduction of 3 (30% improvement; p=0.01 vs. placebo)
- The Primary End-Point for the trial was a reduction of 3 or more in the Activity Impairment Score; 56% of Zydax treated dogs achieved this end-point vs. 40% for placebo (p=0.02).
- Additional trial analysis assessed the spectrum of responses in dogs with early to mid-stage clinical signs of osteoarthritis at enrollment. Zydax treated dogs demonstrated a range of improvements in AIS; after 28 days of treatment with Zydax, 81% of dogs achieved at least an 11% improvement (AIS reduction of ≥1; p=0.02) while 23% of dogs achieved more than 56% improvement (AIS reduction of ≥5; p=0.03).
Chief Scientific Officer Edward Robb, DVM, MS, DACVN, is presenting the comprehensive Zydax data at Parnell's Investor Day being held today in New York City. The presentation will be webcast beginning at 8:30 am Eastern time (details below).
About the Zydax Clinical Trial
The pivotal efficacy clinical trial of Zydax®was conducted as a randomized, double-blinded, placebo-controlled study evaluating the field effectiveness and safety of Zydax in the treatment of clinical signs of osteoarthritis in dogs. The trial, conducted at 20 sites in the U.S. and Australia, included 316 client-owned dogs with radiographic evidence of OA, of which 212 were treated with Zydax and 104 with placebo. The clinical endpoint was improvement in Client Specific Outcome Measures (CSOM) that included dog owners' assessment of improvement in activities such as walking, running and climbing stairs. Treatment was four subcutaneous Zydax injections (or placebo) given one week apart. Measurements were taken at baseline, day 14 (one week after second injection) and day 28 (one week after fourth injection). Clinical outcomes were evaluated at day 28 for a reduction in Activity Impairment Score (AIS) compared to baseline, and no increase in any individual CSOM between day 28 and baseline.
Zydax is Parnell's patented sulfated oligosaccharide with disease-modifying characteristics for the treatment of osteoarthritis (OA) in dogs and horses. Osteoarthritis is a slowly progressing and often severely debilitating joint disease. While currently available treatments for OA, such as anti-inflammatory drugs ease the clinical signs of osteoarthritis for the short term, Zydax is designed to enable veterinarians and animal owners to safely and effectively manage the progression of OA over the life of affected animals. Zydax targets the core deficit of OA by impacting both the anabolic and catabolic pathways of articular cartilage metabolism. Zydax stimulates the growth of new cartilage by modulating proteoglycan synthesis and inhibits the Aggrecanase 1 enzyme, which is responsible for cartilage breakdown. With more than one million doses sold in Australia, New Zealand, Asia and the Middle East, Zydax has led to the improved quality of life for dogs and improved performance of sport horses.
