- PDUFA target action date of May 8, 2027

- If approved, encaleret will be the first and only approved therapy specifically indicated for individuals living with ADH1, representing a potential blockbuster opportunity for BridgeBio

- Encaleret demonstrated consistent efficacy across all pre-specified primary and key secondary efficacy endpoints normalizing key markers of CaSR-driven disease biology without the need for calcium and vitamin D supplements, with a favorable safety and tolerability profile

- BridgeBio is also currently enrolling CALIBRATE-PEDS, a registrational Phase 2/3 trial to study encaleret in pediatric ADH1 and intends to initiate the RECLAIM-HP Phase 3 registrational study of encaleret in chronic hypoparathyroidism later this summer; successful development could extend encaleret’s utility to a broader patient population

PALO ALTO, Calif., July 22, 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) for encaleret for the treatment of individuals living with autosomal dominant hypocalcemia type 1 (ADH1). The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date of May 8, 2027, and BridgeBio is prepared to launch encaleret upon approval, representing a potential blockbuster opportunity for the Company. The FDA also notified the Company that it is not currently planning to hold an advisory committee meeting to discuss the application.

"The FDA's acceptance of our NDA is a powerful validation of encaleret’s differentiated clinical profile and enables a major step forward for the ADH1 community. We believe encaleret has the potential to transform care for patients who currently have no indicated treatment options, and we're moving with urgency to bring it to them," said Ananth Sridhar, Chief Executive Officer of BridgeBio Endocrinology.

CALIBRATE, the Phase 3 clinical trial of encaleret in ADH1, successfully achieved all pre-specified primary and key secondary efficacy endpoints, supporting encaleret’s potential as a disease-modifying therapy by targeting the underlying genetic cause of ADH1. The topline results can be found here . Additional results were presented at the European Congress of Endocrinology (ECE) 2026 and the Endocrine Society 2026 annual meeting (ENDO) in oral presentations, with data showing simultaneous restoration of blood and urine calcium, as well as restoration of physiologic parathyroid hormone (PTH) production.

"For too long, ADH1 has been an invisible condition, that disrupts several systems in the body, from the kidneys to the nervous system to the muscles and often goes unrecognized for years. The path to diagnosis is frequently a long and exhausting one, especially for patients with a genetic disorder. Patients often cycle through specialists before anyone connects the dots to their diagnosis. The FDA's acceptance of this NDA is a moment of real hope for ADH1 patients and a signal that the medical and regulatory community understand the seriousness of this condition and that an orally administered option may finally be on the horizon for those in need," said Patty Keating, Executive Director of the HypoPARAthyroidism Association.

As of April 2026, over 2,100 individuals have been diagnosed in the U.S. with autosomal dominant hypocalcemia since October 2023 based on claims data, suggestive of a growing marketplace and elevated diagnostic suspicion. The Company also intends to submit a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for the use of encaleret in ADH1 in the second half of 2026.

BridgeBio is currently enrolling CALIBRATE-PEDS (NCT07080385), a global registrational Phase 2/3 study of encaleret in pediatric ADH1. The Company also plans to initiate RECLAIM-HP, a global Phase 3 study of encaleret in chronic hypoparathyroidism later this summer, building on the positive Phase 2 proof-of-concept findings of PTH-independent effects of encaleret on renal calcium handling and expanding the potential applications of encaleret beyond ADH1. Successful development could extend encaleret’s utility to a broader patient population.

About Autosomal Dominant Hypocalcemia Type 1 (ADH1)

ADH1 is a common form of genetic hypoparathyroidism caused by gain-of-function variants in the calcium-sensing receptor gene (CASR). The calcium-sensing receptor (CaSR) constantly monitors and balances blood calcium levels by regulating parathyroid hormone secretion and calcium reabsorption in the kidneys. Individuals with ADH1 typically experience hypocalcemia, hypercalciuria, and inappropriately low levels of PTH. Symptoms of hypocalcemia may include severe muscle cramps, muscle spasms (tetany), a burning or prickling sensation in the hands or feet (paresthesia), brain fog, fatigue, and seizures. Hypercalciuria may result in kidney calcification (nephrocalcinosis), kidney stones (nephrolithiasis), and kidney failure.

About Encaleret

Encaleret is an investigational, orally administered small molecule under investigation to treat ADH1 and chronic hypoparathyroidism, that is designed to selectively negatively modulate the calcium sensing receptor. Encaleret has been granted Fast Track Designation by the U.S. FDA and Orphan Drug Designation in the U.S., European Union, and Japan.

About BridgeBio

BridgeBio exists to develop transformative medicines for genetic conditions. Millions of people worldwide living with genetic conditions lack treatment options, often because drug development for small patient populations can be commercially challenging. We aim to bridge the gap between advancements in genetic science and meaningful medicines for underserved patient populations. Our decentralized, hub-and-spoke model is designed for speed, precision, and scalability. Autonomous and empowered teams focus on individual conditions, while a central hub provides the clinical, regulatory, and commercial capabilities needed to bring innovation to market.
