- FDA has approved clinical study design
- 15 Clinical site contracts negotiated
- First enrollment anticipated in Q2-2013
- CPC Clinical Research engaged as CRO
ALPHARETTA, Ga., March 13, 2013 (GLOBE NEWSWIRE) -- SANUWAVE Health, Inc. (OTCBB:SNWV) today provided an update on the Company's clinical trial investigating the dermaPACE® device in the treatment of diabetic foot ulcers.
The U.S. Food and Drug Administration (FDA) has granted full approval of the Company's Investigational Device Exemption (IDE) Supplement to conduct a clinical trial utilizing the dermaPACE device in the treatment of diabetic foot ulcers. This clinical trial provides a scientifically robust and expeditious pathway to a Premarket Approval (PMA) submission to the FDA for their review and consideration of device approval.
"The dermaPACE study design was built off of the positive treatment effect observed in the first study. This study includes several important features which greatly increase the probability of the clinical study's success," stated Mr. Joseph Chiarelli, Chief Executive Officer of SANUWAVE. "These features include:
- Doubling the number of patient treatments - Similar to the previous trial, four (4) dermaPACE procedures will be administered during the first two weeks. In addition, in the upcoming trial, up to four (4) additional dermaPACE procedures will be delivered bi-weekly, between weeks 4 and 10. We believe these additional treatments will increase the between-group difference in complete wound closure in favor of dermaPACE over that observed in the first clinical trial.
- Credit for the positive treatment effect observed in the previous trial - The study uses Bayesian statistical principles, which statistically credits the dermaPACE group at the start of this trial with the positive treatment effect observed in the previous trial. This design also allows for fewer patients than would be enrolled in a standard trial design, with study success potentially occurring with as few as ninety (90) patients.
- Interim monitoring of the data by an independent Data Monitoring Committee (DMC) to determine whether study success has been achieved. This provision has been established in order to monitor the progress of the trial, and ensure its alignment with our statistical plan. The first analysis for making a study success determination is projected to occur after 90 patients (approximately 45 per arm) have completed the 12-week primary efficacy evaluation period.
- Centralized review of digital wound pictures – In addition to the determination of wound closure by each study site's Principal Investigator, an independent group of medical professionals will also assess wound closure. This will provide consistency in determining when a wound is classified as closed. This independent review of wound closure will be performed with the use of a state-of-the-art, digital, wound imaging system.
- Standardized wound debridement guidelines to ensure wounds are debrided aggressively early and then less vigorously as the wounds heal. This will provide consistency among sites in how debridement is performed.
In addition, we have strengthened our internal team with the addition of Joel Batts, Vice President of Clinical Affairs, who will manage the execution of the trial. Joel joined us in October 2011 and has over 13 years of IDE trial experience. He was one of the key architects in designing the new trial.
We have already negotiated contracts with 15 clinical study sites and are in the final stages of qualifying and contracting additional sites to reach our goal of 20 sites by the time of enrollment of the first patient. Patient enrollment is expected to begin in the second quarter of this year. We believe the clinical trial could be completed and the data from the clinical trial available for review in support of a Premarket Approval (PMA) application for dermaPACE as early as the end of 2014, assuming such data to be collected meets the agreed upon statistical and clinical plan of success."
The Company has contracted with CPC Clinical Research (CPC) for database design and management, site monitoring, and core lab services for the dermaPACE clinical trial.
"CPC is pleased to be selected to collaborate with the team at SANUWAVE," said William R. Hiatt, MD, President of CPC and Professor of Medicine at the University of Colorado. "We are primed to apply our industry-leading resources and experiences in wound healing and quality control to the study of diabetic foot ulcers treated with the dermaPACE device."
Mr. Chiarelli concluded, "I'm pleased to announce this collaboration with CPC, a world leading academic clinical research organization, as we move from the planning phase into the execution phase of our dermaPACE clinical trial. The dermaPACE treatment addresses a large, unmet medical need. We remain focused on achieving FDA approval as soon as possible in order to make dermaPACE available to the millions of U.S. patients who suffer from this debilitating, recalcitrant problem."
dermaPACE Phase III Clinical Study Design
SANUWAVE expects to enroll a minimum of 90 patients into the dermaPACE Phase III clinical trial (~45 in the treatment arm and ~45 in the control arm) in 20 sites in the U.S. The clinical study is a prospective, randomized, double-blinded, multicenter, 24-week, parallel group study.
Patients will receive four (4) non-invasive procedures (dermaPACE or control) during the first two weeks. In addition, up to four (4) additional non-invasive procedures (dermaPACE or control) will be delivered bi-weekly, between weeks 4 and 10. The patients will be followed 12 weeks for efficacy and an additional 12 weeks for safety.
The goal of the trial is to establish superiority in diabetic foot ulcer healing rates using the dermaPACE treatment as compared the control group, when both are combined with wet-to-dry dressings and, for some patients, offloading with a walking boot. Secondary trial endpoints included time to closure, reduction in total wound surface area and volume, rate of recurrence and safety assessments. The study's primary endpoint of wound closure is defined as full skin reepithelialization without drainage or dressing requirements confirmed at two consecutive visits.
