Eidos Therapeutics (EIDX) gets bought out by BridgeBio (BBIO)

BridgeBio Pharma (BBIO), a company focused on genetic diseases, and Eidos Therapeutics (EIDX), a company focused on transthyretin (TTR) amyloidosis (ATTR), today announced they have entered into a definitive agreement under which BridgeBio has agreed to acquire all of the outstanding common stock of Eidos it does not already own, representing approximately 36.3% of Eidos’ outstanding shares.

Eidos stockholders will have the right to receive in the transaction, at their election, either 1.85 shares of BridgeBio common stock or $73.26 in cash per Eidos share in the transaction, up to an aggregate maximum of $175 million of cash. The agreement was unanimously approved by BridgeBio’s Board of Directors and was approved by Eidos’ Board of Directors based upon the unanimous recommendation of a special committee of independent directors of Eidos.

With this transaction, BridgeBio fully and formally welcomes Eidos back into its vibrant ecosystem of innovation. Eidos is developing acoramidis, a potential best-in-class TTR stabilizer, for patients with ATTR cardiomyopathy and polyneuropathy.

“With the completion of screening in the Phase 3 ATTRibute-CM study of acoramidis and expected enrollment of more than 600 participants, now is the time to begin laying the groundwork for a global launch. This transaction removes the operational complexity of the current ownership structure and allows us to fully unlock the potential of this investigational medicine for patients and investors,” said Neil Kumar, Ph.D., founder and CEO of BridgeBio and CEO of Eidos. “Bringing Eidos fully back to BridgeBio positions us to invest in all opportunities around acoramidis, including subsequent studies to potentially broaden the evidence for its usage, and accelerate its commercial development using BridgeBio’s established infrastructure. We are excited to welcome acoramidis back into an ecosystem where cutting-edge science is being done across inherited diseases and targeted oncology.”

BridgeBio applies its discover, create, test and deliver platform to target well described genetic diseases at their source. Using this platform Eidos will be able to capitalize on BridgeBio’s global clinical development and regulatory expertise, its developing commercial infrastructure, and its broader capital base to reach more patients more effectively. BridgeBio will be able to invest in novel formulations and studies of acoramidis to maximize its long-term potential benefit to ATTR patients, as well as developing its commercial infrastructure.

Eidos and acoramidis will also become the keystone in BridgeBio’s growing cardiorenal portfolio, which includes drug development in autosomal dominant hypocalcemia type 1 (ADH1) and primary hyperoxaluria type 1 (PH1) as well as undisclosed precision cardiology drug discovery programs.

Eidos completed screening in September for its pivotal Phase 3 ATTRibute-CM clinical trial of acoramidis in patients with ATTR cardiomyopathy. The study is expected to enroll more than 600 subjects with either wild-type or variant TTR across more than 80 sites in 18 countries. Topline results from Part A are expected in late 2021 or early 2022 and from Part B in 2023. If Part A is successful, the company intends to file for regulatory approval of acoramidis in 2022.

BridgeBio expects to launch two drugs, if approved, in 2021 and is building the capabilities necessary to deliver genetic medicines to patients around the globe, which it can deploy for acoramidis.

“ATTR is a rapidly progressive and fatal disease when left untreated, so we know that every moment counts for the patients and families we aim to serve. With Eidos fully reunited with BridgeBio, we intend to move as quickly as possible to advance acoramidis through the development process and, if approved, into the marketplace,” said Cameron Turtle, D.Phil., senior vice president of cardiorenal disease at BridgeBio.

“The special committee of Eidos’ Board believes that this transaction is in the best interest of the Eidos minority stockholders and offers them compelling value,” said William Lis, chairman of the special committee of Eidos’ Board. “The transaction recognizes the significant current value of acoramidis and allows the Eidos minority stockholders to participate in the potential future value of both acoramidis and the broader BridgeBio pipeline of over 20 novel medicines in development for genetic diseases.”

BridgeBio anticipates several meaningful upcoming milestones across its portfolio over the next 12-18 months, including topline Phase 3 Part A data from acoramidis in ATTR cardiomyopathy, Phase 2 data from low-dose infigratinib (FGFR inhibitor) in achondroplasia, Phase 1/2 data from AAV5 gene therapy in congenital adrenal hyperplasia, and Phase 2 data from encaleret (calcium sensing receptor antagonist) in autosomal dominant hypocalcemia type 1.
