Urovant Sciences Parent Company, Roivant Sciences, and Sumitomo Dainippon Pharma Enter into a Memorandum of Understanding to Create Broad Strategic Alliance

Sumitomo Dainippon Pharma plans to support the commercialization of vibegron by leveraging the potential benefits of scale of Sumitomo Dainippon Pharma’s global commercial infrastructure including but not limited to, market access, drug distribution and manufacturing.

“We look forward to this promising new Alliance which provides significant advantages for us as we prepare for the commercial launch of vibegron,” said Keith Katkin, CEO of Urovant. “Our planned NDA filing and launch preparation for vibegron are well underway and will benefit from the partnership of a large, successful multi-national company. In addition, we are excited to have the strategic infrastructure support and proven commercial resources of Sumitomo Dainippon. This relationship should greatly enhance Urovant Sciences’ commercial approach to the US market, strengthens supply chain capabilities and should allow Urovant to fully optimize its launch plan for vibegron.”

Earlier this year, Urovant Sciences announced positive top-line data from the pivotal Phase 3 EMPOWUR trial evaluating vibegron in adults with symptoms of overactive bladder (OAB). Urovant Sciences is planning to submit a New Drug Application (NDA) submission to the U.S. Food and Drug Administration (FDA) by early 2020. Urovant Sciences has also completed enrollment in Part 1 of its two-part Phase 3 study evaluating vibegron for symptoms of overactive bladder (OAB) in men who are receiving pharmacological treatment for benign prostatic hyperplasia (BPH). In addition, Urovant Sciences is enrolling a Phase 2 study evaluating the treatment of vibegron in patients with abdominal pain related to IBS and also expects to start patient enrollment in a Phase 2a trial evaluating novel gene therapy product URO-902 in patients with OAB by the end of the fourth quarter of 2019.
