(Nasdaq: BBIO) (BridgeBio) and Kyowa Kirin Co., Ltd (TSE:4151) (Kyowa Kirin) today announced a partnership wherein BridgeBio’s affiliate, QED Therapeutics, grants Kyowa Kirin an exclusive license to develop and commercialize infigratinib for achondroplasia, hypochondroplasia, and other skeletal dysplasias in Japan. In exchange, BridgeBio will receive an upfront payment of USD 100 million as well as royalties up to the high-twenties percent on sales of infigratinib in Japan, with the potential for additional milestone-based payments. Infigratinib is an oral small molecule designed to inhibit FGFR3 and thus target FGFR3-driven skeletal dysplasias at their source, including achondroplasia and hypochondroplasia. “We are pleased to partner with Kyowa Kirin given their community-oriented core mission to bring smiles to faces by providing innovative medicines with life-changing value, which has seen success with their commercialization of Crysvita and other rare disease drugs. The BridgeBio vision is to help bring people access to novel treatments and trials, and so we are pleased that this collaboration will ensure the development of infigratinib for children living with achondroplasia, and eventually for other skeletal dysplasias in Japan,” said Neil Kumar, Ph.D., BridgeBio’s CEO and founder. “By partnering with Kyowa Kirin, we hope to significantly accelerate the development of infigratinib to potentially provide options for children with achondroplasia, hypochondroplasia, and eventually skeletal dysplasias in Japan. We hear the need from the community for a once-daily oral treatment option and are looking forward to initiating our trials in Japan at a later date,” said Justin To, CEO of QED Therapeutics, BridgeBio’s affiliate for skeletal dysplasias. “We are thrilled to announce that we have signed the License Agreement with BridgeBio,” said Yasuo Fujii, MBA., Chief Strategy Officer, Managing Executive Officer, Vice President, Head of Strategy Division at Kyowa Kirin. “It is important for us to strengthen our portfolio by introducing pipelines in the fields of bone & mineral disorders, including achondroplasia. Based on the results from the latest clinical trials, we believe BridgeBio’s infigratinib has high potential for treating achondroplasia. We will steadily advance the development in Japan and aim to deliver life-changing value to people with skeletal dysplasias including achondroplasia.” In December 2023, BridgeBio dosed the first child in PROPEL 3, a one-year, 2:1 randomized, placebo-controlled Phase 3 pivotal trial, evaluating the efficacy and safety of infigratinib in children with achondroplasia aged 3 to <18 years with open growth plates. The Phase 3 builds on the success of PROPEL 2, a Phase 2 trial of infigratinib in achondroplasia which demonstrated a +3.38cm/yr increase in annualized height velocity, the strongest clinical result published to date. In Japan, Kyowa Kirin will start to discuss with Pharmaceuticals and Medical Devices Agency (PMDA) of Japan in 2024, with the aim of initiating a Japanese registrational trial in 2025. “As the father of a child with achondroplasia, I am keenly aware of the health and mental health issues of people affected by the physical characteristics of living with achondroplasia. GLORY TO ACHONDROPLASIA is deeply grateful for the time spent by researchers and practitioners who support progress in medicine and society, as well as by people affected by the condition and their families. When considering the future of children with achondroplasia, we as a support organization believe it is our absolute responsibility to improve treatment options and social recognition. We are pleased for BridgeBio to partner with Kyowa Kirin and look forward to collaborating on our future responsibilities,” said Eihaku Itooka, founder and president of GLORY TO ACHONDROPLASIA, a Japanese bone dysplasia patient advocacy organization. Information about PROPEL 3 (NCT06164951) can be found here on clinicaltrials.gov. Additionally, BridgeBio expects to initiate ACCEL, an observational lead-in study for infigratinib in hypochondroplasia, a skeletal dysplasia closely related to achondroplasia and similarly driven by FGFR3 gain-of-function variants, in the first half of 2024. BridgeBio has previously presented promising preclinical data for hypochondroplasia at ENDO 2023 and ASHG 2022. About Achondroplasia Achondroplasia is the most common cause of disproportionate short stature, affecting approximately 55,000 people in the U.S. and EU, and 6,000 in Japan. Achondroplasia impacts overall health and quality of life, leading to medical complications such as obstructive sleep apnea, middle ear dysfunction, kyphosis, and spinal stenosis. The condition is uniformly caused by an activating mutation in FGFR3. About BridgeBio Pharma, Inc.

(Nasdaq: BBIO) (BridgeBio), a commercial-stage biopharmaceutical company focused on genetic diseases and cancers, today announced that the first child has been dosed in PROPEL 3, a Phase 3 clinical trial studying the efficacy and safety of infigratinib in children with achondroplasia. Both the U.S. FDA and the EU EMA indicated the trial design for PROPEL 3 would be acceptable as a registrational study to support a marketing application for the treatment of children with achondroplasia. “The Phase 2 data for infigratinib has been very promising and suggests potential to increase growth, improve functionality and reduce the associated medical complications in children with achondroplasia. With the recent dosing of the first child in the Phase 3 trial, I am hopeful that we are one step closer to providing a safe, effective oral therapy to the people in the achondroplasia community who are seeking treatment,” said Dr. Ravi Savarirayan, M.D., Ph.D., clinical geneticist and leader of the molecular therapies research group at the Murdoch Children’s Research Institute in Melbourne, Australia and the global lead investigator for PROPEL 3. PROPEL 3 is a global, one-year, 2:1 randomized, double-blinded placebo-controlled clinical trial, which will evaluate the efficacy and safety of infigratinib in children with achondroplasia aged 3 to <18 years with open growth plates. The primary endpoint will be change from baseline in AHV, with secondary endpoints including proportionality, height Z-score (a measure of variance and dispersion from the average height of children with achondroplasia), and impact on medical complications and quality of life. “We are thrilled about this major milestone for our program and are hopeful about what this means for those families seeking a therapeutic option. We are grateful to the children and their families for participating in our Phase 3 trial as well as the open collaboration we have built with physicians and advocacy groups to best understand the needs of those living with this condition. We look forward to continuing to explore the benefits of infigratinib not only in growth, but in the functional improvements and the alleviation of medical complications that are most meaningful to the community,” said Daniela Rogoff, M.D., Ph.D., senior vice president of clinical development for skeletal dysplasias at BridgeBio. In June 2023, the Company presented updated six-month results from Cohort 5 of PROPEL 2, its Phase 2 dose-finding study, at ENDO 2023. Cohort 5 demonstrated that the dose level of 0.25 mg/kg/day resulted in a significant and robust increase in AHV, with a mean change of +3.38 cm/year from baseline at six months. The findings also highlighted early but promising trends towards improvement in proportionality, as measured by the upper and lower body segment ratio. Additionally, the results showed a well-tolerated safety profile, with no study drug related treatment emergent adverse events, serious adverse events or discontinuations due to adverse events at the 0.25 mg/kg dose. “Achondroplasia can impact the overall health and wellbeing of a person, including functional limitations, social stigma and medical complications. We appreciate the opportunity to work with BridgeBio to ensure the needs of our community are heard, and we are excited by what the Phase 3 study could bring for those looking for options to help themselves or their loved ones,” said Susana Noval, director of Fundación ALPE Acondroplasia.

- BridgeBio completed an end-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA), and a scientific advice engagement with the European Union (EU) European Medicines Agency (EMA) - FDA and EMA alignment was reached on the adequacy of a one-year, 2:1 randomized, placebo-controlled Phase 3 pivotal trial for infigratinib to support a marketing application for the treatment of children with achondroplasia - The primary endpoint will be change from baseline in annualized height velocity (AHV) at 12 months, with secondary endpoints including proportionality, height Z-score and impact on medical complications - These regulatory interactions clear the path for the initiation of PROPEL3 by the end of 2023 - BridgeBio had previously announced a +3.38cm/yr increase from baseline in annualized height velocity (AHV) at six months at 0.25mg/kg/day, with no serious adverse events (SAEs) or adverse events (AEs) assessed as related to study drug PALO ALTO, Calif., Sept. 06, 2023 (GLOBE NEWSWIRE) -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) (BridgeBio), a commercial-stage biopharmaceutical company focused on genetic diseases and cancers, today announced positive feedback from the U.S. FDA and the EU EMA on key elements of the trial design for PROPEL3, its pivotal Phase 3 study of infigratinib in children with achondroplasia. Both regulatory bodies indicated that a single, one-year, 2:1 randomized, placebo-controlled trial would be acceptable as a registrational study for approval, which clears the path for initiation of the trial by the end of 2023. ”The regulatory feedback clearing the path to approval for infigratinib is great news for children living with achondroplasia and for physicians who treat them. It is incredibly exciting that infigratinib has the potential to become the first effective oral treatment option to improve growth, enhance functionality and decrease complications,” said Dr. Melita Irving, M.D., a clinical geneticist at Guy’s and St Thomas’ NHS Foundation Trust, London, UK and investigator for the infigratinib clinical program at the Evelina London Children’s Hospital. PROPEL3, the Phase 3 registrational study is a randomized, double-blinded, multi-site, placebo-controlled clinical trial, which will evaluate the safety and efficacy of infigratinib in children with achondroplasia aged 3 to 18 years with open growth plates. The primary endpoint will be change from baseline in AHV, with secondary endpoints including proportionality, height Z-score, and impact on medical complications. BridgeBio is also committed to exploring the potential of infigratinib on the wider medical and functional impacts of achondroplasia, hypochondroplasia and other skeletal dysplasias, which hold significant unmet needs for families. Based on the positive results to date, the Company has been enrolling children in the run-in for PROPEL3 and expects to initiate PROPEL3 by the end of the year. Cohort 5 of PROPEL2, BridgeBio’s Phase 2 dose-finding study, demonstrated that the dose level of 0.25 mg/kg/day resulted in a significant and robust increase in AHV, with a mean change of +3.38 cm/year from baseline at 6 months. The findings also highlighted early but promising trends towards improvement in proportionality, as measured by the upper and lower body segment ratio study. Additionally, the study has shown a well-tolerated safety profile, with no study drug related treatment emergent adverse events, SAEs or discontinuations due to AEs at the selected dose. ”We are thrilled to have regulatory alignment on key elements of our Phase 3 trial design and the path towards submitting a marketing application to both the FDA and the EMA. We are appreciative of the support from both agencies and plan to move forward swiftly with initiation and dosing in the pivotal trial, with the hopes of providing a much needed oral option to children with achondroplasia,” said Adora Ndu, Pharm.D., J.D., chief regulatory officer of BridgeBio. Additionally, BridgeBio expects to initiate clinical development for infigratinib in hypochondroplasia, a skeletal dysplasia closely related to achondroplasia and similarly driven by FGFR3 gain-of-function variants. BridgeBio has previously presented promising preclinical data for hypochondroplasia at ENDO 2023 and ASHG 2022.
