Takeda and Frazier Healthcare Partners Announce Collaboration to Launch HilleVax, Inc. to Develop Clinical Stage Norovirus Vaccine Candidate

Takeda Pharmaceutical Company Limited (TSE:4502/NYSE:TAK) (Takeda) and Frazier Healthcare Partners (Frazier) today announced a collaboration to launch HilleVax, Inc. (HilleVax), a biopharmaceutical company to develop and commercialize Takeda’s norovirus vaccine candidate. Takeda has granted a license to HilleVax for the exclusive development and commercialization rights to its norovirus vaccine candidate, HIL-214 (formerly TAK-214), worldwide outside of Japan, in exchange for upfront consideration, as well as future cash milestones and royalties on net sales. Takeda will retain commercialization rights in Japan and HilleVax will integrate certain Japan development activities into its global development. Takeda remains committed to vaccines, and this collaboration allows Takeda to focus its global resources on dengue, COVID-19, pandemic influenza and Zika, in addition to the vaccines it currently distributes in Japan.

HIL-214, which is a virus-like particle (VLP) based vaccine candidate, completed a randomized, placebo-controlled Phase 2b field efficacy study in 4,712 adult subjects in which HIL-214 was well-tolerated and demonstrated clinical proof of concept in preventing moderate-to-severe cases of acute gastroenteritis from norovirus infection.¹ To date, the candidate has been studied in nine human clinical trials with safety data from over 4,500 subjects and immunogenicity data from over 2,000 subjects.

“Takeda and Frazier have a history of successfully partnering together, and we are confident in HilleVax’s capabilities to progress HIL-214, the most advanced norovirus vaccine candidate in development with the potential to address the huge global burden of norovirus-associated acute gastroenteritis,” said Rajeev Venkayya, M.D., President of the Global Vaccine Business Unit, Takeda. “This will allow Takeda to focus its efforts and resources on our dengue vaccine, which we have begun filing for licensure around the world, our pandemic programs, and our partnership with the US Government to develop a Zika vaccine.”

Norovirus is a common intestinal infection marked by diarrhea, vomiting, abdominal cramps, nausea and sometimes fever that may lead to clinically significant dehydration.² Norovirus is recognized as the leading cause of acute gastroenteritis across the age spectrum.³ It is estimated that norovirus causes nearly 700 million cases of illness and more than 200,000 deaths worldwide per year with significant additional economic and social burden.³ No vaccines are currently approved for norovirus infection, and HIL-214 continues to be the most advanced norovirus vaccine candidate in human clinical trials.

“Following our successful partnership to form Phathom Pharmaceuticals, we are extremely pleased to partner again with Takeda to form HilleVax,” said Tachi Yamada, M.D., co-founder of HilleVax and Venture Partner with Frazier. “Norovirus causes significant morbidity and mortality as well as tremendous economic and social costs worldwide. We believe that HIL-214 represents an important opportunity to address this immense unmet need.”
