Pilot Study 12-Month Results
A pilot study was conducted in Calgary, Alberta and included 10 patients who underwent treatment with Viveve’s CMRF technology under a proprietary treatment protocol. Patients were followed for 12 months with safety and clinical results reported at 4, 6, 9 and 12 months post-treatment. Clinical results included composite scores from the validated ICIQ-UI-SF (International Consultation on Incontinence Questionnaire–Urinary Incontinence-Short Form) and UDI-6 (Urogenital Distress Inventory-Short Form) outcome questionnaires. Results at 12 months (n=9) included an 89-100% responder rate (percentage of patients showing an improvement from baseline) and a 40-51% mean improvement at 12 months across both validated endpoints, respectively. No device-related safety issues were reported in any of the patients. The pilot study was conducted by Bruce Allan, PhD, MD, FRCS(C), founder and medical director of the Allan Centre.
“Our practice has treated women with vaginal laxity using Viveve’s CMRF technology for more than five years. For SUI, the combined cooling and deep tissue capability of CMRF effectively targets the connective tissue that plays a critical role in the structural integrity of the vagina and the urinary system. In the pilot study, we found that SUI symptoms were significantly improved, providing strong support for the planned clinical registration studies and the potential to represent a major advance in the non-invasive treatment of SUI,” said Dr. Allan.“Based on the positive patient responses seen in the pilot study, including sustained reduction of symptoms at 12 months, Viveve has committed to move forward with two robust clinical registration trials to further assess the safety and efficacy of the Viveve System in the treatment of mild-to-moderate SUI,” said Patricia Scheller, chief executive officer and director of Viveve, Inc. “The global market for the non-invasive treatment of SUI, estimated at $10 to $12 billion, represents a major market opportunity for Viveve.”
International Registration Study Overview - LIBERATE (International)
LIBERATE (International) is intended to be a randomized, double-blind, sham-controlled study conducted in up to 10 sites in Canada and including up to 100 patients suffering from mild-to-moderate SUI. The primary efficacy endpoint is expected to be the 6-month change from baseline in the one-hour pad weight test and will include 12 months of safety follow-up, as well as assessments in other secondary endpoints. The Company is currently in the process of reviewing the protocol with Health Canada, and if the results of the study are positive, expects to use the outcome of this study for a registration filing in Canada and for CE Mark application in the EU for the temporary improvement of mild-to-moderate SUI symptoms.
U.S. Registration Study Overview - LIBERATE (U.S.)
LIBERATE (U.S.) is intended to be a randomized, double-blind, sham-controlled study in up to 25 centers across the U.S. and including up to 200 patients suffering from mild-to-moderate SUI. The primary efficacy endpoint is expected to be the 12-month change from baseline in the one-hour pad weight test and will include 12 months of safety follow-up, as well as assessments in other secondary endpoints. The Company anticipates submitting an Investigational Device Exemption (IDE) to the U.S. Food and Drug Administration (FDA) for the temporary improvement of mild-to-moderate SUI symptoms.
“SUI is very costly to treat and is a highly prevalent condition that affects millions of women worldwide. The expansion of our product portfolio into this indication demonstrates the unique versatility of our globally patented CMRF platform, as well as our continued commitment to scientific rigor and extensive clinical evidence,” Ms. Scheller continued. “We are excited by the potential for a single, non-invasive treatment that can have a profoundly positive impact on women’s quality of life in the estimated $10 to $12 billion global market for the treatment of SUI.”
About Stress Urinary Incontinence
Stress urinary incontinence is a medical condition affecting an estimated 25-30 million women worldwide. It is a major challenge for women, particularly those who have experienced childbirth or are menopausal. Upwards of 55% of women with a previous vaginal delivery may exhibit symptoms of SUI. The need to use an external pad to absorb urine leakage associated with even normal activities such as coughing or laughing is unsatisfactory, inconvenient, often embarrassing and negatively impacts a woman’s quality of life. Currently available and effective treatment options are extremely limited. Pelvic floor exercises (Kegels) and muscle strengthening products offer some benefit, but compliance and sustained benefit can be an issue. More aggressive approaches to manage SUI include pelvic surgery, slings and mesh. These options involve risk and recovery time and are a last resort for many patients. The ability to offer a minimally invasive, safe and effective treatment option for SUI using Viveve’s CMRF technology would address an enormous unmet healthcare need for women.
