  • Eidos grants Alexion exclusive license to develop and commercialize AG10 in Japan
  • Phase 3 study of AG10 in ATTR cardiomyopathy underway in U.S. & Europe; Phase 3 trial in ATTR polyneuropathy planned to initiate in second half of 2019
  • Agreement expands Alexion’s amyloidosis portfolio
  • Eidos to receive upfront payment of $25 million and equity investment of $25 million, with potential for additional Japanese-based milestone- & royalty-dependent payments –

BOSTON & SAN FRANCISCO – SEPTEMBER 9, 2019 Alexion Pharmaceuticals, Inc. (NASDAQ:ALXN) and BridgeBio Pharma, Inc.’s (NASDAQ:BBIO) subsidiary Eidos Therapeutics, Inc. (NASDAQ:EIDX) today announced an agreement that grants Alexion an exclusive license to develop and commercialize AG10 in Japan. AG10 is a small molecule designed to treat the root cause of transthyretin amyloidosis (ATTR) – destabilized and misfolded transthyretin (TTR) protein – by binding and stabilizing TTR in the blood. Eidos is currently evaluating AG10 in a Phase 3 study in the U.S. and Europe for ATTR cardiomyopathy (ATTR-CM) – a progressive, fatal disease caused by the accumulation of misfolded TTR amyloid in the heart – and plans to begin a Phase 3 study in ATTR polyneuropathy (ATTR-PN) – a progressive, fatal disease caused by the accumulation of misfolded TTR amyloid in the peripheral nervous system.

“There is a significant need for new treatments for TTR amyloidosis. We believe AG10 holds promise in its ability to stabilize TTR and halt disease progression,” said John Orloff, M.D., Executive Vice President and Head of Research & Development at Alexion. “We are excited by the potential to grow our amyloidosis portfolio by partnering with Eidos to expand the development of AG10 to Japan. Alexion has more than 10 years of experience operating there, and we look forward to applying our expertise to bring AG10 to Japanese patients.”

“The Phase 2 study in ATTR-CM suggested that AG10 has the potential to become an important treatment option for the underserved ATTR-CM population. The trial showed that AG10 was generally well-tolerated and resulted in near-complete stabilization of TTR, which is known to be correlated with disease severity in ATTR-CM. In the study, AG10 also normalized serum TTR levels, a prognostic indicator of survival in ATTR patients,” said Jonathan Fox, M.D., Ph.D., President and Chief Medical Officer of Eidos. “We have now begun our Phase 3 program to evaluate the safety and efficacy of AG10 in larger studies. This agreement provides the potential opportunity to help even more patients globally by leveraging Alexion’s significant development and commercial experience to expand the AG10 program into Japan.”

Under the terms of the agreement, Alexion will acquire an exclusive license for the clinical development and commercialization of AG10 in Japan. Eidos will receive an upfront payment of $25 million and an equity investment of $25 million at a premium to the market price upon deal execution, with the potential for additional Japanese-based milestone- and royalty-dependent payments.

About AG10

AG10 is an investigational, orally-administered small molecule designed to potently stabilize tetrameric transthyretin, or TTR, thereby halting at its outset the series of molecular events that give rise to TTR amyloidosis, or ATTR. In a Phase 2 clinical trial in patients with symptomatic ATTR-CM, AG10 was generally well tolerated, demonstrated greater than 90 percent average TTR stabilization at Day 28, and increased serum TTR concentrations, a prognostic indicator of survival in a retrospective study of ATTR-CM patients, in a dose-dependent manner.

AG10 was designed to mimic a naturally-occurring variant of the TTR gene (T119M) that is considered a rescue mutation because co-inheritance has been shown to prevent or ameliorate ATTR in individuals also inheriting a pathogenic, or disease-causing, mutation in the TTR gene. To our knowledge, AG10 is the only TTR stabilizer in development that has been observed to mimic the stabilizing structure of this rescue mutation.

The Phase 3 ATTRibute-CM study of AG10 in patients with ATTR-CM is underway in the United States and Europe. Part A of the study will assess the change from baseline in 6-minute walk distance (6MWD) at 12 months. Part B of the study will evaluate reduction in all-cause mortality and frequency of cardiovascular-related hospitalizations will be evaluated at 30 months. In addition, Eidos plans to initiate a Phase 3 study of AG10 in ATTR polyneuropathy (ATTR-PN) in the second half of 2019.

About Transthyretin Amyloidosis (ATTR)

There is significant medical need in transthyretin amyloidosis (ATTR) given the large patient population and an inadequate current standard of care. ATTR is caused by the destabilization of TTR due to inherited mutations or aging and is commonly divided into three distinct categories: wild-type ATTR cardiomyopathy (ATTRwt-CM), mutant ATTR cardiomyopathy (ATTRm-CM), and ATTR polyneuropathy (ATTR-PN). The worldwide prevalence of each disease is approximately 400,000 patients, 40,000 patients and 10,000 patients, respectively.

All three forms of ATTR are progressive and fatal. For patients with untreated ATTRwt-CM and ATTRm-CM, symptoms usually manifest later in life (age 50+), with median survival of three to five years from diagnosis. ATTR-PN either presents in a patient’s early 30s or later (age 50+), and results in a median life expectancy of five to ten years from diagnosis for untreated patients. Progression of all forms of ATTR causes significant morbidity, impacts productivity and quality of life, and creates a significant economic burden due to the costs associated with progressively greater patient needs for supportive care.

BridgeBio Pharma’s Origin Biosciences Presents New Data on the Natural History of Molybdenum Cofactor Deficiency (MoCD) Type A at the Society of the Study of Inborn Errors of Metabolism (SSIEM) Conference

  • This landmark study is a comprehensive global survey of the natural history of MoCD Type A
  • Results continue to suggest urgent need for new therapies in MoCD Type A, with median survival of <4 years and rapid disease onset within the first month of life for most patients
  • Continue to anticipate initiating a rolling New Drug Application submission for our first-in-class therapy for MoCD Type A, BBP-870, over the coming months

SAN FRANCISCO, Sept. 05, 2019 (GLOBE NEWSWIRE) — BridgeBio Pharma, Inc. (Nasdaq: BBIO) subsidiary Origin Biosciences announced today the presentation of a study on the natural history of patients with Molybdenum Cofactor Deficiency (MoCD) and isolated sulfite oxidase deficiency (ISOD). The study was presented at the 2019 SSIEM Annual Symposium held in Rotterdam, Netherlands.1

In this comprehensive natural history study, 65 patients with MoCD and ISOD were enrolled from 27 participating centers across 14 countries. The majority of patients had MoCD Type A (n=37), followed by MoCD Type B (n=16) and Other (n=12). Data were collected retrospectively for all patients and prospectively for patients in the living cohort for up to one year. The primary endpoint was survival at 1 year of age.

For MoCD Type A patients, the probability of survival at 1 year of age was 0.72 (0.535-0.845) and median survival was 3.98 years. Nearly all patients (n=57) had first presenting symptoms by Day 28 with median onset for MoCD Type A patients at 2 days. The most common initial symptoms were seizures and feeding difficulties. Other subsequent symptoms included developmental delay, truncal hypotonia with limb hypertonia, and cortical blindness. Median urinary S-sulfocysteine and xanthine concentrations were extremely high, and uric acid levels were drastically low in the first few days of life. Additional biochemical and neuroimaging data were collected. These data were presented during the Disorders of vitamins, cofactors and trace elements poster session at SSIEM. See below for a detailed summary of the data.

“Our findings confirm that the vast majority of MoCD and ISOD cases are severe, rapidly progressive, and neurodegenerative, resulting in significant disability and early lethality in almost all cases from the neonatal age,” said Ronen Spiegel, MD, Clinical Associate Professor, Director of Pediatric B Department, and Head of Metabolic Service, Emek Medical Center, principal investigator and lead author of the study.

Currently there are no approved therapies that alter the course of MoCD or ISOD. BridgeBio Pharma, through its subsidiary Origin Biosciences, is developing BBP-870 (ORGN001), a cPMP substrate replacement therapy that targets MoCD Type A directly at its source. By restoring the natural molybdenum cofactor synthetic pathway, the compound aims to reduce buildup of toxic sulfites and alleviate symptoms in infants and children with MoCD Type A. BBP-870 (ORGN001) has received Orphan Drug Designation in the US and Europe, Rare Pediatric Disease Designation and Breakthrough Therapy Designation from the FDA, and is currently being evaluated in a global Phase 2 clinical trial and a global Phase 2/3 clinical trial (NCT02629393NCT02047461).

About Molybdenum Cofactor Deficiency (MoCD)

MoCD is a rare, autosomal recessive, inborn error of metabolism caused by disruption in molybdenum cofactor (MoCo) synthesis that is vital for sulfite oxidase (SOX) activity. Patients are often infants with severe encephalopathy and intractable seizures. Disease progression is rapid with a high infant mortality rate.1,2 Those who survive beyond the first few months experience profuse developmental delays and suffer the effects of irreversible neurological damage, including brain atrophy with white matter necrosis, dysmorphic facial features, and spastic paraplegia.1,4 Clinical presentation that can be similar to hypoxic-ischemic encephalopathy (HIE) or other neonatal seizure disorders may lead to misdiagnosis and underdiagnosis.2,3 Immediate testing for elevated sulfite levels and S-sulfocysteine in the urine and very low serum uric acid may help with suspicion of MoCD.2,4

About Origin Biosciences

Origin Biosciences, a subsidiary of BridgeBio Pharma, is a biotechnology company focused on developing and commercializing a treatment for Molybdenum Cofactor Deficiency (MoCD) Type A. Origin is led by a team of veteran biotechnology executives. Together with patients and physicians, the company aims to bring a safe, effective treatment for MoCD Type A to market as quickly as possible.

BridgeBio Pharma expands its research into neuromuscular disease to include Limb-Girdle Muscular Dystrophy Type 2i (LGMD2i) with new subsidiary ML Bio Solutions

Provides BridgeBio with leading scientific expertise to develop oral small molecule therapy for LGMD2i

CHARLOTTE, NC and SAN FRANCISCO, CA – September 5, 2019 – BridgeBio Pharma, Inc. (NASDAQ: BBIO) today announced ML Bio Solutions as a new subsidiary dedicated to developing BBP-418, a substrate supplementation therapy for the treatment of Limb-Girdle Muscular Dystrophy Type 2i (LGMD2i). BridgeBio is committing R&D expertise to advance this small molecule oral therapy towards patients and intends to begin a natural history study in the second half of 2019, with interventional trials to initiate as soon as possible thereafter, subject to IND approval. The McColl Lockwood Laboratory for Muscular Dystrophy Research at Atrium Health will continue to support the program alongside BridgeBio.

LGMD2i is an autosomal recessive disease wherein loss-of-function mutations in the FKRP gene lead to decreased glycosylation of alpha-dystroglycan (α-DG). Properly-glycosylated α-DG anchors muscle cells to proteins outside of the cell in the extracellular matrix (ECM) as well as shock absorber proteins inside of the muscle cells, such as dystrophin. In LGMD2i, α-DG has a defective sugar backbone, and thus cannot effectively bind these proteins to stabilize the muscle cell, leading to muscle cell fragility and damage under stress. Damaged and degenerating muscle cells can result in global loss of muscle strength. LGMD2i is a progressive and debilitating disease that affects an estimated 7,000 patients across the US and EU, with more affected globally. It is associated with loss of mobility and ultimately respiratory and cardiac failure, and there is presently no approved treatment.

ML Bio Solutions’ compound BBP-418 aims to bypass the core metabolic defect in LGMD2i by providing a pro-drug [to the other enzymes in the pathway] that can be metabolized into the missing substrate in the α-DG sugar backbone. This therapeutic approach originates from the discovery and translational work of scientific co-founder Dr. Qi Long Lu, director of the McColl-Lockwood Laboratory for Muscular Dystrophy Research at Atrium Health, as published in a Nature Communications article in 2018. A brief overview of the program can be found in the investor section of the BridgeBio website.

“By combining the scientific leadership of the McColl-Lockwood Laboratory with the rare disease development expertise at BridgeBio, we believe we can accelerate the path to making a safe and effective disease-modifying treatment available to LGMD2i patients as soon as possible,” said Luther Lockwood, chairman of the board and President of ML Bio Solutions.

“BBP-418 is a novel approach that targets LGMD2i at the source of disease, and exemplifies the BridgeBio mission of creating life-altering medicines by pairing well-understood genetically- driven phenotypes with treatments whose mechanisms target the sources of disease,” said Uma Sinha, Ph.D, chief scientific officer of BridgeBio Pharma. “We are thrilled to partner with the foremost experts in the field to explore the translation of these important discoveries into clinical impact for patients who currently lack effective treatment options.”

Eidos Therapeutics Initiates Attribute-CM, a Phase 3 Study of AG10 in ATTR-CM with Registrational 12-month Endpoint

ATTRibute-CM study design, which incorporates feedback from the FDA, has the potential to accelerate registration with a 12-month primary endpoint of change in 6-minute walk distance (6MWD), followed by a 30-month endpoint of mortality and cardiovascular-related hospitalizations

Trial sites activated in global Phase 3 study (ATTRibute-CM) of AG10 in patients with transthyretin amyloidosis cardiomyopathy

Eidos to Host Conference Call and Webcast at 8am ET

SAN FRANCISCO, Feb. 27, 2019 (GLOBE NEWSWIRE) — Eidos Therapeutics, Inc. (Eidos) (Nasdaq:EIDX), today announced the initiation and design of its pivotal global Phase 3 trial (ATTRibute-CM) of AG10 in patients with transthyretin (TTR) amyloid cardiomyopathy (ATTR-CM). The design of the ATTRibute-CM study, which incorporates feedback from FDA, includes two potentially registrational endpoints. In Part A, benefit in change from baseline in 6-minute walk distance (6MWD) will be evaluated at 12 months, potentially accelerating the time to registration. In Part B, reduction in all-cause mortality and frequency of cardiovascular-related hospitalizations will be evaluated at 30 months.

“ATTRibute-CM aims to generate registrational evidence that AG10 provides meaningful benefit to ATTR-CM patients. The trial is designed to evaluate preservation of function and quality of life on an accelerated timeframe in addition to evaluating longer-term benefit on mortality and cardiovascular-related hospitalizations,” said Jonathan Fox, MD, PhD, president and chief medical officer of Eidos. “If successful, this trial could lead to an approval of AG10 for the treatment of ATTR-CM, a disease with significant unmet medical need and limited treatment options.”

The ATTRibute-CM study advances clinical development of AG10 following positive results from a Phase 2 trial in subjects with symptomatic ATTR-CM. In that study, AG10 was shown to be generally well-tolerated and significantly increase serum transthyretin, a biomarker associated with survival in a retrospective study of ATTR-CM patients, in a dose-dependent manner. All subjects treated with AG10 achieved normal serum transthyretin levels within 28 days of treatment, even those whose baseline levels were well below normal. Results of this study were presented in a late-breaking Featured Science oral presentation at the Annual Scientific Sessions of the American Heart Association in November 2018. An open-label extension of this study is ongoing.

ATTRibute-CM Design

ATTRibute-CM will enroll approximately 510 subjects with symptomatic ATTR-CM, associated with either wild-type or mutant TTR, with New York Heart Association Class I-III symptoms. Subjects will be randomized 2:1 between treatment (AG10 800 mg) and placebo twice daily. In Part A, change in 6MWD at 12 months will be compared between treatment and placebo groups as the first registrational primary endpoint. In Part B, the study will continue for a total duration of 30 months, at which point all-cause mortality and frequency of cardiovascular-related hospitalizations will be compared between treatment and control groups. Secondary endpoints include quality of life as assessed by the Kansas City Cardiomyopathy Questionnaire, safety parameters, serum TTR levels, and TTR stabilization. In Part B, concomitant use of approved, indicated therapies may be allowed.

About AG10

AG10 is an investigational, orally-administered small molecule designed to potently stabilize tetrameric transthyretin, or TTR, thereby halting at its outset the series of molecular events that give rise to amyloidosis, or ATTR. In a Phase 2 clinical trial in subjects with symptomatic ATTR-CM, AG10 was generally well tolerated, demonstrated >90% average TTR stabilization at day 28, and increased serum TTR concentrations, a prognostic indicator of survival in a retrospective study of ATTR-CM patients, in a dose-dependent manner. AG10 is currently being studied in an open-label extension of a Phase 2 clinical trial in patients with ATTR-CM and sites are currently being activated for a Phase 3 clinical trial of AG10 in patients with ATTR-CM (ATTRibute-CM).

AG10 was designed to mimic a naturally-occurring variant of the TTR gene (T119M) that is considered a rescue mutation because co-inheritance has been shown to prevent ATTR in individuals also inheriting a pathogenic, or disease-causing, mutation in the TTR gene. To our knowledge, AG10 is the only TTR stabilizer in development that has been observed to mimic the stabilizing structure of this rescue mutation.

About transthyretin amyloidosis (ATTR)

ATTR represents a significant unmet medical need with a large patient population and an inadequate current standard of care. ATTR is caused by the destabilization of TTR due to inherited mutations or aging and is commonly divided into three distinct categories: wild-type ATTR cardiomyopathy (ATTRwt-CM), mutant ATTR cardiomyopathy (ATTRm-CM), and ATTR polyneuropathy (ATTR-PN). The worldwide prevalence of each disease is approximately 400,000 patients, 40,000 patients and 10,000 patients, respectively.

All three forms of ATTR are progressive and fatal. For patients with ATTRwt-CM and ATTRm-CM, symptoms usually manifest later in life (age 50+), with median survival of three to five years from diagnosis. ATTR-PN either presents in a patient’s early 30s or later (age 50+), and results in a median life expectancy of five to ten years from diagnosis. Progression of all forms of ATTR causes significant morbidity, impacts productivity and quality of life, and creates a significant economic burden due to the costs associated with progressively greater patient needs for supportive care.

Phoenix Tissue Repair Doses First Patient in Phase 1/2 Clinical Trial of PTR-01 (BBP-589) for Treatment of Recessive Dystrophic Epidermolysis Bullosa (RDEB)

BOSTON, Feb. 22, 2019 /PRNewswire/ — Phoenix Tissue Repair, Inc., a biotechnology company focused on developing transformational disease-modifying treatments for dystrophic epidermolysis bullosa (DEB), today announced that the first patient has been dosed in the Phase 1/2, first in-human trial of PTR-01 (BridgeBio Pharma designation BBP-589), a protein replacement therapy for recessive DEB (RDEB). DEB and RDEB are rare genetic multisystem disorders associated with severe skin blistering, and treatment is currently limited to palliative symptom management.

“Dosing the first patient in the clinic is an important milestone for the development of PTR-01 as a potential treatment for RDEB,” said Dr. Neil Kirby, President and Chief Executive Officer of Phoenix Tissue Repair. “The community of RDEB patients, families and physicians urgently need effective treatments for this devastating disease. With an approach that aims to target the root cause of the disease, we are optimistic that PTR-01 could provide hope to patients and their families.”

DEB is a rare genetic disorder symptomatic from birth that is caused by mutations in the gene encoding collagen type VII protein (C7). Symptoms include extreme skin and mucosal fragility and can also include erosions and scarring of other mucous membranes throughout the body. Severe comorbidities are common, and patients require intensive and constant care. DEB, and RDEB in particular, is associated with a considerable reduction in quality-of-life and life span. There are currently no approved disease-modifying therapies for any form of DEB.

The PTR-01-001 Phase 1/2 trial will enroll 14 patients who will each be dosed over a 10-week period. The primary objective of the trial is to evaluate the safety, tolerability and pharmacokinetics of PTR-01 in RDEB patients. The trial will also assess various secondary endpoints. To learn more about the PTR-01 Phase 1/2 clinical trial, please visit www.clinicaltrials.gov and search the identifier NCT03752905.

About Dystrophic Epidermolysis Bullosa (DEB)

DEB is a rare genetic disorder symptomatic from birth that is caused by mutations in the gene for a protein called collagen type VII (C7). C7 is essential for the formation of anchoring fibrils, structures which connect the uppermost two layers of the skin, the epidermis and dermis. Patients with RDEB tend to have particularly severe symptoms due to severe insufficiency of functional C7. Symptoms include extreme skin and mucosal fragility that presents as recurrent, painful blistering and scarring of the skin; ulcerations of the mouth and tongue, and dental caries. In addition to the cutaneous and oral symptoms, severe forms are associated with erosions and scarring of mucous membranes of the eye, esophagus, genitals, and anus. Joint contractures, mutilating deformities of hands and feet, malnutrition, growth retardation, recurrent infections, and a significantly increased risk for squamous cell carcinoma are also common. There are currently no approved disease-modifying therapies for any form of DEB, and the standard of care focuses on wound and pain management.  

About PTR-01

Phoenix Tissue Repair is advancing an investigational therapy known as PTR-01, a protein replacement therapy which uses a recombinant collagen type VII (rC7) for the potential treatment of RDEB. PTR-01 is designed to be systemically available through intravenous delivery. Phoenix Tissue Repair acquired worldwide rights to PTR-01 in 2017. Preclinical studies of PTR-01 have demonstrated C7 distributes to the basement membrane of the skin, and was observed to restore anchoring fibrils, promote healing and improve survival.

PTR-01 has been granted Orphan Drug Designation by the U.S. Food and Drug Administration and the European Medicines Agency.

About the Phase 1/2 Clinical Trial

The PTR-01-001 trial is a saline-controlled, single-blind, multiple ascending dose, dose-escalation, multi-center study. Patients will be enrolled into one of three cohorts. Cohorts 1, 2 and 3 will consist of two, four and eight patients, respectively. During the Treatment Period a total of three doses of PTR-01 and three doses of saline control will be administered to all patients for a total of six doses in a cross-over design over a 10-week period. The primary objective of the trial is to evaluate the safety, tolerability and pharmacokinetics of PTR-01 in RDEB patients. Additionally, the trial will assess the proof of biologic activity through skin biopsy evaluation of C7 and the presence of anchoring fibrils. Wound healing and clinically meaningful patient reported outcomes will also be evaluated. To learn more about the PTR-01 Phase 1/2 clinical trial, please visit www.clinicaltrials.gov and search the identifier NCT03752905.

QED Therapeutics Announces a Collaboration with Foundation Medicine to Develop Companion Diagnostics for Infigratinib

SAN FRANCISCO, Dec. 10, 2018 /PRNewswire/ — QED Therapeutics today announced that it has entered into an agreement with Foundation Medicine to develop a companion diagnostic for infigratinib, an FGFR1-3 selective tyrosine kinase inhibitor, in patients with cholangiocarcinoma. The companion diagnostic, which will include detection of activating FGFR2 fusions, is expected to be incorporated into FoundationOne®CDx, Foundation Medicine’s FDA-approved comprehensive genomic profiling (CGP) assay for all solid tumors that includes multiple companion diagnostics.

“While targeted therapies have transformed the treatment landscape for multiple cancers, such as lung cancer, cholangiocarcinoma has not yet benefitted from these advances,” noted Susan Moran, M.D., M.S.C.E., chief medical officer of QED Therapeutics. “Given infigratinib’s demonstrated promise in FGFR2 fusion-driven cholangiocarcinoma, a companion diagnostic is critical to help physicians reliably identify which patients might be candidates for treatment.”

About QED Therapeutics

QED Therapeutics, a subsidiary of BridgeBio Pharma, is a biotechnology company focused on precision medicine for FGFR-driven diseases. Our lead investigational candidate is infigratinib (BGJ398), an orally administered, FGFR1-3 selective tyrosine kinase inhibitor that has shown meaningful clinical activity in patients with chemotherapy-refractory cholangiocarcinoma with FGFR2 fusions and advanced urothelial carcinoma with FGFR3 genomic alterations. QED is also evaluating infigratinib in preclinical studies for the treatment of achondroplasia and other skeletal dysplasias. We plan to conduct further clinical trials to evaluate infigratinib in additional FGFR-driven tumor types and rare disorders.
