IRVINE, Calif., Sept. 19 /PRNewswire-FirstCall/ -- ISTA Pharmaceuticals, Inc. today announced its Fall 2005 schedule for presenting clinical data on its product, Vitrase(R) (Ovine Hyaluronidase), which is currently FDA approved for use as a spreading agent for hypodermoclysis and as an adjunct in subcuteanous urography. Details regarding the clinical presentations are provided below:
Evaluation of preservative-free, highly purified hyaluronidase ovine (Vitrase(R)), 200 USP units/mL, as an adjuvant to increase the absorption and dispersion of other injected drugs prior to ocular surgery
Abstract No. 6396 -- Lack of hypersensitivity reactions to hyaluronidase ovine (Vitrase(R))
October 25, 2005
Abstract No. 6423 -- Retrobulbar block: the role of Vitrase(R) (hyaluronidase ovine) as an adjuvant to reduce the time required between injection of anesthetic and surgical incision
"We are very excited to announce the upcoming schedule of presentations relating to Vitrase as a spreading agent at major, clinically oriented meetings this fall," stated Vicente Anido, Jr., Ph.D., President and Chief Executive Officer of ISTA Pharmaceuticals. "Each of these poster or podium presentations will provide further confirmation of the safety and efficacy of Vitrase, the only purified, preservative-free spreading agent and adjunct on the market. We believe that Vitrase's demonstrable safety record is due to its purity and the fact that this product is formulated without the preservative agent thimerosal, an organomercurial which is broadly implicated in neurotoxicity and has been the subject of intense debate in the health sciences community and regulatory agencies for some time."
Dr. Anido continued, "We have previously reported that Vitrase has shown 0% incidence of allergic hypersensitivity in over 1100 patients, which is testimony to the quality of our sourcing and manufacturing of this breakthrough product. In addition, studies of Vitrase in retrobulbar block have shown pain-free surgery for most patients, with 95% reporting no ocular pain during the procedure. The presentations scheduled this fall will provide further confirmation of these findings, and we will announce details of these data at the time of their presentation. Overall, we believe that, given the same or superior results in terms of activity and safety, physicians will use the most convenient and cost-effective product as a spreading agent, and we further believe that we have demonstrated and will continue to demonstrate that Vitrase fits this profile."
Further, Andrew Iwach, M.D., an Associate Clinical Professor of Ophthalmology at the University of California at San Francisco, added that "Vitrase has improved the surgical experience. The speed at which Vitrase works to facilitate anesthesia makes my pre-op procedures more efficient and allows for a more efficient operating environment while helping to increase the comfort of my patients."
ABOUT VITRASE(R)
ISTA's Vitrase(R) is a proprietary formulation of highly purified ovine hyaluronidase. In May 2004, the FDA approved Vitrase(R) in a lyophilized 6200 USP Units multi-purpose vial for use as a spreading agent; a 200 USP Units/mL vial in sterile solution for use as a spreading agent was approved in December 2004. FDA's approval of Vitrase for use as a spreading agent in May 2004 removed hyaluronidase from the FDA's drug shortage list where it had been listed since 2001.
In addition to its approval for use as a spreading agent, for hypodermoclysis and as an adjunct in subcuteanous urography, Vitrase(R) has been studied for the treatment of vitreous hemorrhage. A New Drug Application, or NDA, was filed for the treatment of vitreous hemorrhage in 2002 and an approvable letter for that NDA was received in 2003. In the letter, the FDA cited issues primarily related to the sufficiency of the efficacy data submitted with the NDA. The FDA requested additional analysis of the existing data and an additional confirmatory clinical study based upon that analysis. Vitrase(R) has also been studied for the treatment of diabetic retinopathy.
