AlphaRx and Proprius Pharmaceuticals Announce Top Line Results from Indaflex(TM) Phase II Study in Canada

MARKHAM, Ontario and SAN DIEGO, CA | Posted on May 15th, 2007

The randomized double-blind placebo and vehicle controlled trial, which
included a six week treatment period, was conducted in 233 patients with OA
of the knee. The primary endpoints used in the trial were the change from
baseline to week six in the global Western Ontario and McMaster
Universities Osteoarthritis Index (WOMAC) score and the subject's global
assessment of efficacy. While the trial did not meet its primary endpoints,
subgroup analyses of patients with moderate to severe pain and more
impaired physical function at baseline showed positive trends in patients
treated with Indaflex(TM) as compared to patients treated with either
placebo or vehicle. Indaflex(TM) was demonstrated to be safe and well
tolerated.

"We are encouraged by the results of this first human efficacy trial
comparing Indaflex(TM) to both placebo and vehicle," said Michael J. Walsh,
President & CEO of Proprius Pharmaceuticals. "The data point to the promise
of Indaflex(TM) as a very well tolerated and safe topical NSAID product
candidate, with potential for efficacy in treating moderate to severe pain
and improving function for patients suffering from osteoarthritis of the
knee. The knowledge gained from this proof of concept study has provided
important insights on appropriate pivotal trial design. We are eager to
discuss our findings with the Food and Drug Administration, and advance
Indaflex into registration trials."

Dr. Lee S. Simon, a Rheumatologist and former Director of the Food and
Drug Administration's Analgesic, Anti-Inflammatory and Ophthalmic Drug
Products Division, and a consultant to the companies, commented, "The
results of this initial clinical trial provide supportive evidence for the
efficacy and safety of Indaflex(TM). This therapeutic product candidate has
the potential to fulfill the need for an effective, tolerable and safer
alternative to either oral non-selective NSAIDs or COX-2 selective
inhibitors for the treatment of osteoarthritis of the knee, as well as
other diseases and disorders which are associated with localized pain and
inflammation."
