BridgeBio Announces Infigratinib Is the First Ever Investigational Therapeutic Option for ...
- Breakthrough Therapy Designation was granted based on preliminary clinical evidence from the PROPEL 2 clinical trial, meeting the FDA’s requirement of potentially demonstrating substantial improvement in efficacy over available therapies on clinically significant endpoint(s)
- BridgeBio will leverage the benefits of Breakthrough Therapy Designation to expedite the development and regulatory review of infigratinib in the United States and if approved, infigratinib could be the first-in-class oral therapeutic option for children living with achondroplasia
- In Cohort 5 of PROPEL 2 (0.25 mg/kg/day), oral treatment with infigratinib resulted in a statistically significant and sustained increase in annualized height velocity (AHV), with a mean change from baseline of +2.51cm/yr at Month 12, and +2.50 cm/yr at Month 18 (p=0.0015) and statistically significant improvement in body proportionality at Month 18 (p-value of 0.001)
PALO ALTO, Calif., Sept. 17, 2024 (GLOBE NEWSWIRE) -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) (BridgeBio), a commercial-stage biopharmaceutical company focused on genetic diseases, today announced that the FDA has granted Breakthrough Therapy Designation to oral infigratinib under development for children with achondroplasia.
Breakthrough Therapy Designation is designed to expedite the development and regulatory review of drugs in the U.S. that meet stringent criteria. Drugs qualifying for this Designation must show preliminary clinical evidence that the drug may demonstrate a substantial improvement on clinically significant endpoints over available therapies.
“The receipt of Breakthrough Therapy Designation, the first ever for a treatment being developed for children with achondroplasia, marks another important milestone for our skeletal dysplasia program. This recognition by the FDA further confirms the strength of our Phase 2 data, and the substantial improvement on clinically significant endpoints over available therapies. We are excited by what this means for the community, and we look forward to working closely with FDA to expedite the development of infigratinib and access for families to an oral option,” said Adora Ndu, Pharm.D., J.D., Chief Regulatory Affairs Officer of BridgeBio.
The Designation was received based on PROPEL 2 data, which showed that in Cohort 5, infigratinib resulted in a statistically significant and sustained increase in AHV, with a mean change from baseline of +2.51cm/yr at Month 12, and +2.50 cm/yr at Month 18 (p=0.0015). There was also statistically significant improvement in body proportionality at Month 18 (p-value of 0.001).
“From the outside perspective, achondroplasia may appear to affect only the height of an individual. The reality is that achondroplasia is a skeletal dysplasia which could impact aspects of health-related quality of life and functionality. As a parent of a teenager with achondroplasia and an advocate for the community, I am pleased to learn that the FDA has granted infigratinib with its Breakthrough Therapy Designation,” said Munira Shamim, Founder of Growing Stronger, a U.S. advocacy group that supports research and develops resources for the care of individuals with achondroplasia. “This action represents a significant step towards offering the first oral treatment option more readily for families living with achondroplasia. Having a wider range of therapies empowers families with greater control and choice over their healthcare decisions. We are grateful to the medical, research, and regulatory communities for recognizing and addressing the needs of families with achondroplasia, allowing them to potentially lead lives with increased confidence and improved functionality.”
PROPEL 3, the global Phase 3 registrational study of infigratinib in achondroplasia, continues to enroll on schedule, with completion of enrollment anticipated by the end of the year. Information about PROPEL 3 ( NCT06164951 ) can be found on clinicaltrials.gov. BridgeBio is committed to exploring the potential of infigratinib on wider medical and functional impacts of achondroplasia, hypochondroplasia and other skeletal dysplasias, which hold significant unmet needs for families.
In addition to receipt of Breakthrough Therapy Designation, infigratinib has also received Orphan Drug Designation, Fast Track Designation, and Rare Pediatric Disease Designation for achondroplasia from the FDA. If infigratinib is approved, BridgeBio may qualify for a Priority Review Voucher.
