Final Results From Below-The-Knee Cohort In Chocolate Registry Presented At The 5th Annual Amputation Prevention Conference


- Chocolate® Balloon Angioplasty Registry represents one of the largest single studies ever conducted of interventions in patients with below-the-knee arterial disease

- Dr. Jihad Mustapha, Principal Investigator, concluded that treatment with Chocolate® PTA shows improved outcomes when compared to use of traditional PTA balloons in similar populations

PLEASANTON, Calif., Aug. 31, 2015 /PRNewswire/ -- QT Vascular Ltd., together with its subsidiaries (the "Company" or "QT Vascular", and together with its subsidiaries, the "Group"), a global company engaged in the design, assembly and distribution of advanced therapeutic solutions for the minimally invasive treatment of vascular disease, announced today the final results of the below-the-knee ("BTK") cohort of patients in the Chocolate® Balloon Angioplasty Registry ("BAR") which were presented on August 15, 2015 at the 5th Annual Amputation Prevention Symposium in Chicago, Illinois by the Principal Investigator, Dr. Jihad Mustapha, of Metro Health Hospital, Wyoming, Michigan.

Based on historical outcomes with conventional balloon angioplasty reported in the literature1-3, BTK patients treated with Chocolate® percutaneous transluminal angioplasty ("PTA") Balloon Catheter ("Chocolate® PTA") in this study showed a lower rate of unplanned stenting, a lower rate of repeat interventions, a lower incidence of amputation and lower overall mortality. A randomized controlled study would further define the potential treatment benefit of the Chocolate® PTA for BTK lesions.

"A significant part of my practice is treating patients with BTK disease. These patients have more progressed disease and are often at risk for higher complication rate including amputation and even death," commented Dr. Mustapha. "The results from Chocolate® BAR are very positive. Drug coated balloons have not yet shown to be effective for interventions below the knee. With Chocolate® PTA, even without a drug, we now have the tool to improve outcomes in this very sick group of patients."

The Chocolate® BAR is an observational registry collecting data on real world use with the Chocolate® PTA to assess its effectiveness in achieving optimal PTA procedural outcomes and to assess potential longer-term clinical benefits. A total of 226 BTK patients were enrolled and agreed to undergo three months follow-up and a cohort of 123 patients was scheduled for six months follow-up. In addition, 264 above-the-knee ("ATK") patients were enrolled for a total of 490 patients treated at 33 US centers. The final results for the ATK patient cohort will be presented later in 2015.

"It is very gratifying to see patients treated with Chocolate® PTA to have low rates of bail-out stenting, repeat interventions, and amputations. The BTK patients are in a need for a solution and the results of the Chocolate® BAR are encouraging," stated Dr Eitan Konstantino, PhD, Chief Executive Officer of QT Vascular. "We are focused on continued innovation and believe that our pipeline of drug coated devices will add meaningful value to patients and healthcare providers."
