Oculus Innovative Sciences Announces Publication of Microcyn Technology Post-Caesarean Section Wound Study in Indian Medical Gazette
Researchers at the Grant Medical College and Sir J.J. Group of Hospitals in Byculla, Mumbai, randomized 50 patients who had undergone caesarean section. Patient wounds were treated with Oxum (Microcyn Technology group) (n=25) or povidone iodine (control group) (n=25) topically twice a day for 10 days. Assessments were made on days five and 10. Primary outcome measures included complete healing, partial healing and non-healing on days five and 10. The efficacy evaluation was based on appearance, presence or absence of odor, discharge, necrotic tissue, and granulation tissue at the site of the wound. The patients were also assessed based on symptoms such as pain, edema, redness, dryness and itching. Doctors evaluated global efficacy and patients evaluated global tolerability.
The authors reported that surgical wound signs and symptoms assessments indicate that more of the patients in the Oxum-treated group showed healing on day 10 compared to the povidone-iodine-treated group. All the patients (100%) in both groups had partially healed surgical wounds on day five, whereas on day 10, 24 patients (96%) in the Oxum group and 22 patients (88%) in the povidone-iodine group were completely healed.
Surgical assessment of wound signs at day five showed a benefit favoring the Oxum group in healthy appearance, absence of odor, presence of granulation tissue and lack of indolent stitches. Surgical wound symptom assessment at day five also showed a better outcome for the Oxum-treated group as evaluated by pain, edema, redness and dryness of the wound.
Similarly, the global efficacy evaluation demonstrated a "good-to-excellent" efficacy response in a greater number of Oxum-treated patients as compared to the povidone-iodine-treated group (on a graduated scale of poor, moderate, good and excellent).
The conclusion of researchers was that Oxum (Microcyn Technology) "is safe and effective in post-caesarean wound care management and provides for better efficacy and faster response as compared to a povidone-iodine topical application in post-caesarean section wound care management."
Hoji Alimi, founder and CEO of Oculus, commented, "This is an example of a novel application for Microcyn, in which the dual nature of the technology -- both its antimicrobial efficacy and its wound healing capability -- promoted wound healing in these incisions. With the increasing incidence of caesarean sections performed worldwide and the higher rates of post-operative infections, it is imperative that the medical community be given access to new and alternative treatment options. Surgical site infections (SSIs), including those potentially seen post-operatively in caesarean sections, can be a tremendous burden on the global healthcare system and patients. As a result, we will further examine Microcyn Technology's possible role in the treatment of these various surgical applications as we evolve our clinical program."
About Caesarean Section
A caesarean section or c-section is a form of childbirth in which a surgical incision is made through a mother's abdomen (laparoscopy) and uterus (hysterectomy) to deliver one or more babies. It is usually performed when a vaginal delivery would put the baby's or mother's life or health at risk, although in recent times it has also been performed upon request for births that would otherwise have been normal.
The World Health Organization estimates the rate of caesarean sections at between 10% and 15% of all births in developed countries. In 2004, the caesarean rate was about 20% in the United Kingdom while in the United States the caesarean rate has risen 46% since 1996, reaching a level of 30.2% in 2005.
According to a 2001 study published by F.G Cunningham, "Caesarean delivery and post partum hysterectomy," the incidence of abdominal incision infections following caesarean delivery ranged from 3% to 15% with an average of 6% during caesarean section delivery.
A proper post-surgical wound care regimen thus becomes an extremely important factor in preventing the occurrence of infection. An effective wound care product should address the most important aspects of infection control and safety. If infection is present in the wound, standard treatment includes cleansing and either surgical or mechanical debridement and sometimes oral or intravenous antibiotics. An ideal wound care product, in addition to controlling the infection, should also protect the normal tissues and not interfere with the normal wound healing.
Oculus Innovative Sciences is a biopharmaceutical company that develops, manufactures and markets a family of products based upon the Microcyn(R) Technology platform, which is intended to help prevent and treat infections in chronic and acute wounds. The Microcyn Technology platform is a biocompatible, shelf-stable solution containing active oxychlorine compounds that is currently commercialized outside the United States for the treatment of infected wounds. The solutions derived from the Microcyn Technology platform have demonstrated, in a variety of research and investigational studies, the ability to treat a wide range of pathogens, including antibiotic-resistant strains of bacteria (including MRSA and VRE), viruses, fungi and spores. In the United States, Dermacyn(TM) Wound Care (formulated with Microcyn Technology) has received three 510k clearances from the FDA for cleaning, debriding, moistening and lubricating wounds.
A recently completed U.S. Phase II clinical trial of Microcyn Technology met the primary endpoints of safety and efficacy for the treatment of mildly infected diabetic foot ulcers.
Oculus' principal operations are in Petaluma, California, and it conducts operations in Europe, Latin America and Japan through its wholly owned subsidiaries, Oculus Innovative Sciences Netherlands B.V., Oculus Technologies of Mexico, S.A. de C.V. and Oculus Japan K.K.
