In conjunction with the Series A financing, Jeff Terrell, General Partner of Hatteras Venture Partners, has joined the Boomerang Board of Directors.

“We are thankful for the support of our new and existing investors as we look to expand device-oriented treatment options for people with autoimmune diseases,” said Heather Simonsen, President and Chief Executive Officer of Boomerang Medical. “We are especially proud to announce this financing as a woman-led company, after watching the proportion of venture funding dollars drop from 2.8 percent in 2019 to 1.9 percent thus far in 2022 for companies with a female at the helm, a decline we are helping to reverse.”

“Heather and her team, with strong support from Fogarty Innovation, have reached critical milestones in a very short amount of time, culminating in their recent approval by the Food and Drug Administration to commence the Boomerang Clinical Trial for patients with IBD,” said Jeff Terrell, General Partner, Hatteras Venture Partners. “Hatteras is delighted to support Boomerang’s efforts to develop novel therapies in this area of significant unmet clinical need.”

It is estimated that more than 50 million people in the U.S. have an autoimmune disease, accounting for an annual burden to the overall healthcare system of more than $100 billion. One of the most prevalent and costly is Inflammatory bowel disease (IBD), including its most common forms: Crohn’s disease and ulcerative colitis. The onset of IBD usually occurs in young adulthood, is a lifelong condition, and affects nearly all aspects of living-including patients’ private, occupational and social lives. Research over the past 20 years has shown that stimulating certain nerve pathways may help regulate an overactive immune response in people with IBD and other autoimmune diseases.

Tom Shehab, MD, Managing Partner at Arboretum Ventures added, “The seasoned team at Boomerang is well-suited to advance its device-oriented approach with strong potential to address historically hard-to-treat autoimmune conditions. This investment reflects our belief in the Boomerang platform and the company’s ability to execute towards their vision. We look forward to supporting the team in its clinical efforts and working to combat the increasing incidence of Inflammatory Bowel Disease.”
