Oculus Innovative Sciences Announces Publication of Microcyn Technology Diabetic Wound Study in Journal of College of Physicians and Surgeons Pakistan

PETALUMA, Calif.--(BUSINESS WIRE)--April 15, 2008 - Oculus Innovative Sciences, Inc. (Nasdaq: OCLS) announced today that the Journal of College of Physicians and Surgeons Pakistan has published results from a randomized and controlled study of the company's Microcyn(R) Technology in 100 patients in Pakistan with infected diabetic wounds. In this study, Microcyn showed a statistically significant benefit versus saline with respect to the primary endpoints: duration of hospital stay, downgrading of the wound category and wound healing time. A reprint of the peer-reviewed paper, entitled "Treating Infected Diabetic Wounds with Superoxidized Water as Anti-Septic Agent," is available online at: http://www.oculusis.com/jcpsp.pdf.

Researchers at the Pakistan Institute of Medical Sciences in Islamabad, Pakistan randomized 100 diabetic patients with infected wounds. Patients received Microcyn (intervention group) or normal saline (control group) in combination with ofloxacin, an intravenous antibiotic, until wound healing. Each patient's wound was classified into one of four grades depending on the presence of the following characteristics: Grade 4, necrotic tissue or frank pus; Grade 3, slight slough or serosanguinous secretion; Grade 2, granulation tissue; and Grade I, healthy epithelialization considered as healing. All patients had prior surgical wound treatment and received their assigned study treatment (Microcyn or saline). Local wound treatment consisted of twice-daily application of Microcyn-soaked gauzes in the intervention group and normal saline in the control group.

As shown in tables 1 and 2, statistically significant differences were apparent in favor of the intervention group with respect to the duration of hospital stay, downgrading of the wound category and wound healing time (p value less than 0.05 in all categories).

Most of the infected patients with wounds grade IV (61.76%) and grade III (70%) healed within one week of Microcyn therapy in comparison to a lower healing rate in patients treated with topical saline (14.7% and 20%, respectively). Even wounds with granulation tissue achieved a faster complete epithelialization, if they were assigned to the study agent (100%) instead of saline (50%). As a result, 62% of the patients in the study group were discharged from the hospital in less than seven days in comparison to only 20% of those receiving saline. -0-

These results are relevant considering that all patients were on systemic antibiotics as well. They suggest that Microcyn could be inducing wound healing by mechanisms different from the sole mechanical debridement or the reduction of microbial load in the wound. The authors discuss the favorable cost-benefit ratio of this novel topical therapy in terms of better outcomes, patient satisfaction, antibacterial spectrum, control of antibiotic resistant pathogens, simplicity of use and lower costs of attention. They conclude that, based on these positive results, further multi-center clinical trials are warranted.

Hoji Alimi, founder and CEO of Oculus, commented, "Results from this study support prior findings from 23 global Microcyn studies involving more than 800 patients. These data also complement positive top-line results from our U.S. Phase II study of Microcyn as a treatment for mildly infected diabetic foot ulcers, which showed a 93% clinical success rate as a monotherapy versus just 56% for the levofloxacin plus saline-treated patients at the test of cure visit on day 24 in the clinically evaluable patient population. Based upon this continued and consistent validation of the Microcyn technology, we look forward to advancing our U.S. clinical program and exploring additional commercial opportunities with our current and future partners."

Oculus presented positive results from the recently completed U.S. Phase II trial assessing the safety and efficacy of the Microcyn Technology in the treatment of mildly infected diabetic foot ulcers at DFCon 08, a premier international diabetic foot conference held in March: http://www.oculusis.com/phase2data_update/.
