Exhibit 99.1
BridgeBio Announces FDA Acceptance and Priority Review of NDA for
Oral Infigratinib for Children with Achondroplasia
- Accepted for Priority Review with a PDUFA target action date of February 4, 2027; being granted Priority Review by the FDA underscores the significant unmet need for an oral targeted therapeutic option for children with achondroplasia
- If approved, oral infigratinib would be the first and only approved oral therapy and a potential best-in-class treatment option for children with achondroplasia
- PROPEL 3 met its primary endpoint and key secondary endpoints, delivering the strongest efficacy package reported to date in achondroplasia: the largest AHV treatment effect of any Phase 3 study (+2.10 cm/yr; p<0.0001), and the first and only statistically significant improvement in both body proportionality and arm span in an achondroplasia Phase 3 trial (Proportionality: mean difference of -0.05 in ages 3–8, p<0.05; arm span z-score: +0.37 SD, p<0.0001)
-Treatment with oral infigratinib for 52 weeks in PROPEL 3 also resulted in favorable trends against placebo in clinically meaningful exploratory endpoints including sleep apnea and otitis media events
- BridgeBio anticipates U.S. launch of oral infigratinib upon approval
PALO ALTO, Calif., Oct. 06, 2026 (GLOBE NEWSWIRE) -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) ("BridgeBio" or the "Company"), a commercial-stage, multi-product biopharmaceutical company focused on developing medicines for genetic conditions, today announced the FDA has accepted for filing its New Drug Application (NDA) with Priority Review for oral infigratinib for the treatment of children with achondroplasia. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date of February 4, 2027, and BridgeBio is prepared to launch oral infigratinib upon approval.
"Being granted Priority Review means we are one step closer to potential FDA approval of the first oral treatment option for children with achondroplasia," said Justin To, Chief Executive Officer of BridgeBio Skeletal Dysplasias. "We also understand that for many families, it’s about more than just height or having an oral option. To that end, we are excited by the data we have generated on arm span, sleep apnea, ear infections, and proportionality, and we remain committed to further evaluate and share the impact of oral infigratinib on measures beyond growth. We are grateful to the families and investigators who have partnered with us, and we are moving with urgency alongside the FDA."
PROPEL 3, the global Phase 3 pivotal study of oral infigratinib in children with achondroplasia, met its primary endpoint of change from baseline in annualized height velocity (AHV) at Week 52 (LS mean treatment difference of +1.74 cm/year; mean treatment difference of +2.10 cm/year; p<0.0001) and its key secondary endpoint of change from baseline in height Z-score (p<0.0001). In a pre-specified exploratory analysis in children younger than 8 years (more than half of participants), oral infigratinib became the first therapeutic option to show a statistically significant improvement in body proportionality against placebo in a randomized achondroplasia trial. Oral infigratinib was well tolerated, with no discontinuations or serious adverse events related to study drug. These data were published as an original research article in The New England Journal of Medicine and simultaneously presented at the International Congress of Children’s Bone Health (ICCBH) 2026 in a late-breaking oral presentation. The results can be found here. Additionally, BridgeBio also shared emerging data for oral infigratinib at ESPE about improvements beyond height for people with achondroplasia, including stabilizing sleep apnea measures, reducing rate of ear infections, and impacting body composition. The results can be found here.
“For children and families living with achondroplasia, today’s news represents meaningful progress toward potentially expanding the range of available options,” said Michael Hughes, Chair of the Biotech Industry Liaison Committee at Little People of America. “Our community holds diverse priorities and perspectives, and what matters is that individuals and families have meaningful choices as they consider their own healthcare goals. This milestone brings us one step closer to potentially having another option for families to consider together with their healthcare providers. We appreciate BridgeBio’s continued engagement with the achondroplasia community and its efforts to incorporate community perspectives throughout the development process.”
BridgeBio intends to submit a Marketing Authorization Application (MAA) for achondroplasia to the European Medicines Agency (EMA) in the fourth quarter of 2026.
Oral infigratinib has received Breakthrough Therapy Designation from the FDA based on results from the PROPEL 2 clinical trial, which met the FDA’s requirement of potentially demonstrating substantial improvement in efficacy over available therapies on clinically significant endpoints. Oral infigratinib is the only therapeutic option in development for achondroplasia to hold Breakthrough Therapy Designation. In addition, oral infigratinib has received Orphan Drug Designation, Fast Track Designation, and Rare Pediatric Disease Designation for achondroplasia from the FDA, as well as Orphan Drug Designation from the EMA.
Information about PROPEL I&T trial (NCT07169279) can be found here on clinicaltrials.gov. Information about ACCEL, the Company’s observational lead-in study for oral infigratinib in hypochondroplasia’s Phase 3 study (NCT06410976) can be found here, and information about ACCEL 2/3, BridgeBio’s Phase 2/3 clinical study of oral infigratinib in hypochondroplasia (NCT06873035) can be found here. BridgeBio is committed to exploring the potential of oral infigratinib on wider medical and functional impacts of achondroplasia, hypochondroplasia, and other skeletal dysplasia conditions, which hold significant unmet needs for families.
About Achondroplasia
Achondroplasia is the most common cause of disproportionate short stature, affecting approximately 55,000 people in the U.S. and European Union (EU), including up to 10,000 children and adolescents with open growth plates. Achondroplasia can be associated with medical complications such as obstructive sleep apnea, middle ear dysfunction, kyphosis, and spinal stenosis, which may impact overall health and wellbeing. The condition is uniformly caused by an activating variant in FGFR3.
About Oral Infigratinib
Oral infigratinib is an investigational small molecule designed to inhibit FGFR3 signaling and target skeletal dysplasias, including achondroplasia and hypochondroplasia, at their source. Overactivating FGFR3 pathogenic variants drive downstream MAPK and STAT1 signaling that aberrates growth plate development, thereby causing disproportionate short stature and the potential for serious health complications. Oral infigratinib improves bone growth by decreasing the overactivity of FGFR3. Oral infigratinib has received Breakthrough Therapy Designation, Orphan Drug Designation, Fast Track Designation, and Rare Pediatric Disease Designation from the U.S. FDA, as well as Orphan Drug Designation from the European Medicines Agency (EMA).
About BridgeBio
