USGI Medical Inc. (USGI) has completed a pilot study of its incisionless, endoscopic gastroplasty procedure, known as POSE2.0, which evaluated weight loss in adults suffering from obesity (body mass index [BMI] 35-40 kg/m²) who have an obesity-related comorbidity, such as diabetes or hypertension. Completing the pilot study lays the foundation for future regulatory submissions to enable marketing of POSE2.0 devices in the United States.
The pilot study encompassed four sites and 40 U.S. patients, and was led by principal investigator Barham Abu Dayyeh, M.D., of the Mayo Clinic (Rochester, Minn.). Investigators evaluated patients’ safety, weight loss, and other effectiveness factors. Patients received lifestyle and nutritional care through one year.
“There is a growing body of global evidence that appears promising regarding the potential impact of this gastric remodeling procedure on obesity and related comorbidities,"1 Dayyeh said.
POSE2.0 uses USGI Medical’s Incisionless Operating Platform (IOP) to strategically place durable Snowshoe Suture Anchors in gastric tissue to both shorten and narrow the stomach. The procedure provides volumetric gastric restriction, like that achieved by a surgical sleeve gastrectomy, without surgically removing part of the stomach. Patients treated with the POSE2.0 procedure typically return to normal activities and lifestyles faster, compared to traditional laparoscopic and open abdominal surgery.
“As a pioneer in incisionless weight loss procedures, this acceptance marks an important milestone for USGI in validating the safety, durability and potential effectiveness of POSE2.0 devices for primary obesity," USGI Medical CEO Arnold Podgorsky stated. "It also reflects our ongoing collaboration with leading bariatric specialists from around the world. We look forward to advancing a U.S. pivotal study for a primary obesity indication and continuing to build value for our shareholders.”
Obesity is an increasing, global public health issue. Patients with obesity are at major risk for developing a range of comorbid conditions, including cardiovascular disease (CVD), gastrointestinal disorders, type 2 diabetes, joint and muscular disorders, respiratory problems, and psychological issues, which may significantly affect their daily lives as well as increasing mortality risks. Obesity‐associated conditions are manifold; however, even modest weight reduction may enable patients to reduce their risk for CVD, diabetes, obstructive sleep apnea, and hypertension among many other comorbidities.2 A relatively small and simple reduction in weight, for example, of around 5%, can improve patient outcomes and may act as a catalyst for further change, with sustainable weight loss achieved through a series of incremental weight loss steps. According to the Center for Disease Control and Prevention, the prevalence of obesity among U.S. adults today is approximately 40%, a rate that has grown significantly over the preceding decades, putting financial strains on the U.S. healthcare system with annual medical costs totaling more than $150 billion.
USGI Medical develops technologies to enable incisionless surgery—i.e., treating diseases through the body's natural passageways. USGI's Incisionless Operating Platform provides physicians the operating platform and specialized tools they need to perform procedures through a patient's mouth or other natural orifices. USGI has demonstrated the capability to suture GI tract tissue reliably and durably without an incision, opening the way to a new generation of treatments for a wide variety of acute and chronic diseases. Operating through the body's natural orifices offers promise for less pain, shorter hospital stays, reduced risk of wound infection along with no external scarring from abdominal incisions, and is rapidly becoming an option demanded by patients and healthcare providers. USGI offers surgeons and gastroenterologists the tools they need to offer millions of potential patients a less invasive option to surgery.
The Incisionless Operating Platform, including the g-Cath EZ Delivery Catheter with Snowshoe Suture Anchors, has both CE Mark and U.S. Food and Drug Administration 510(k) clearance for tissue approximation. The safety and effectiveness of the device has not been established in the United States so as to permit marketing for the treatment of obesity. The device is considered an investigational device in the United States and is thereby limited by federal law to investigational use for obesity treatment.
