BridgeBio Pharma’s Origin Biosciences Initiates Rolling Submission Of New Drug Application With The U.S. FDA For BBP-870 For The Treatment Of MoCD Type A

BOSTON, December 3, 2019 – BridgeBio Pharma, Inc. (Nasdaq: BBIO) subsidiary Origin Biosciences has initiated a rolling submission of a New Drug Application (NDA) with the United States Food and Drug Administration (FDA) for fosdenopterin (BBP-870/ORGN001) for the treatment of patients with molybdenum cofactor deficiency (MoCD) Type A.

Currently, there are no approved therapies that alter the course of MoCD Type A, which results in severe and irreversible neurological injury. Fosdenopterin, an investigative cPMP substrate replacement therapy, aims to reduce buildup of toxic sulfites and alleviate central nervous system symptoms in infants and children with MoCD Type A.

“Initiation of our rolling NDA submission is a significant milestone for our company and an important step in providing a therapy to patients and their families living with MoCD Type A,” said Origin Biosciences CEO Neil Kirby, Ph.D. “We look forward to making fosdenopterin available to infants and children with this devastating disease as soon as possible as they currently have no treatment options that target the disease at its source.”

“BridgeBio was founded to develop breakthrough medicines for patients with genetic diseases. As we begin our first rolling new drug application with the FDA, we are taking a significant step forward for patients by targeting MoCD Type A at its source through the provision of the monophosphate cPMP. We want to thank patients and their families, the scientists, and all others involved who helped us reach this critical moment,” BridgeBio CEO Neil Kumar, Ph.D., said. “Our growing company has more than 15 drug discovery and development programs. We hope Origin’s NDA will be the first of many we submit to the FDA in our pursuit of life-changing therapies for patients, including an anticipated submission in 2020 from BridgeBio subsidiary QED Therapeutics for infigratinib for second line treatment of cholangiocarcinoma.”

The regulatory submission will primarily be supported by data from two ongoing trials, a global Phase 2 clinical trial (NCT02629393) and a global Phase 2/3 clinical trial (NCT02047461). Under its rolling review process, the FDA can review components of a marketing application as they are submitted rather than requiring all components to be received prior to initiating review, potentially allowing for faster review of the application.

BBP-870 has received Orphan Drug Designation in the US and Europe, and Rare Pediatric Disease Designation and Breakthrough Therapy Designation in the US. Since the NDA for fosdenopterin is seeking approval of treatment for patients with a serious and life-threatening disease with no other treatment options (MoCD Type A), it is also eligible for Priority Review Designation, which, if granted, may further expedite the NDA review time for the NDA approval of this new medicine.

About Molybdenum Cofactor Deficiency (MoCD) Type A

MoCD Type A is an ultra-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 Type A.2,4

PellePharm Completes Enrollment of Pivotal Phase 3 Clinical Trial of Patidegib Topical Gel in Patients with Gorlin Syndrome

– Trial rapidly enrolled in 8 months

– Trial size expanded to accommodate 24 more patients than planned

SAN FRANCISCO – December 2, 2019 – PellePharm, Inc., a BridgeBio Pharma, Inc. (Nasdaq: BBIO) company, today announced the completion of enrollment for its pivotal Phase 3 clinical trial of Patidegib Topical Gel 2% vs. vehicle gel in patients with Gorlin Syndrome. PellePharm is a late clinical-stage biopharmaceutical company committed to targeting rare forms of basal cell carcinoma.

“Patients living with Gorlin Syndrome undergo recurring, invasive surgical treatments that result in facial scarring, potential loss of vital facial structure and function, and impact to their quality of life,” said Sanuj K. Ravindran, M.D., president and chief executive officer of PellePharm. “Significant enthusiasm for the trial allowed us to enroll the study quickly, but only after enrolling approximately 16% more patients than originally planned to accommodate the incredible interest from patients. We continue to be encouraged about Patidegib Topical Gel’s potential and are grateful for the overwhelming support of the Gorlin Syndrome community worldwide, including the researchers, clinicians, patients and caregivers working diligently to bring promise to this devastating disease.”

The randomized, double-blind, vehicle-controlled Phase 3 trial is evaluating the safety and efficacy of Patidegib Topical Gel 2% applied, twice daily to the face over 12 months vs. vehicle gel. An open-label safety and tolerability extension study is planned for at least 12 months following the end of the study for patients who complete the Phase 3 trial, and for those who completed the Phase 2 Gorlin Syndrome trial.

“This is a very important milestone for PellePharm and the broader Gorlin Syndrome community, and we’re thrilled to be one step closer to our goal of bringing Patidegib Topical Gel to patients living with Gorlin Syndrome, a condition for which there is no FDA-approved therapy,” said Thorsten Thormann, vice president of global research at LEO Pharma.

As of November 2018, PellePharm and LEO Pharma entered into a strategic collaboration to address the unmet medical needs for rare skin conditions, such as Gorlin Syndrome and High Frequency Basal Cell Carcinoma (HF-BCC). LEO Pharma is providing resources to PellePharm to fund, amongst other activities, its Phase 3 trial of Patidegib Topical Gel 2% in patients with Gorlin Syndrome under the terms of the agreement.

About Patidegib

Patidegib Topical Gel, an investigational treatment, is designed to reduce the BCC tumor burden in patients with Gorlin Syndrome and High Frequency BCC (HF-BCC) by blocking the disease at its source within the hedgehog signaling pathway. Patidegib Topical Gel has shown early promise in a Phase 2 clinical study for the mitigation of BCC tumors in Gorlin Syndrome. The topical formulation of Patidegib was developed with a goal of providing the clinical activity previously demonstrated by oral Patidegib in Phase 1 trials and a favorable tolerability profile without the adverse systemic side effects observed with the oral class of hedgehog inhibitors. The topical gel formulation is stable at room temperature for at least two years, potentially making it an option for ongoing, at-home management of Gorlin Syndrome and HF-BCC. PellePharm has received both Orphan Drug Designation and Breakthrough Therapy Designation for Patidegib Topical Gel in Gorlin Syndrome from the FDA, as well as Orphan Drug Designation in Gorlin Syndrome from EMA’s Committee for Orphan Medicinal Products in the EU.

About Gorlin Syndrome

Gorlin Syndrome is a rare, genetic disease characterized by constitutional, heritable mutations in one allele of the tumor suppressor gene encoding PATCHED1 (PTCH1), which acts as the primary inhibitor of the hedgehog signaling pathway. This leads to the formation of multiple basal cell carcinomas, often on the face.

With no FDA-approved drugs available for patients with Gorlin Syndrome, the standard of care for treating BCCs is surgery. People with severe Gorlin Syndrome may have as many as 30 surgeries per year, which can be repetitive, scarring and disfiguring. Approximately 10,000 people in the United States, or one in 31,000, are believed to be affected by Gorlin Syndrome. Gorlin Syndrome is known by several names, including Gorlin-Goltz Syndrome, Basal Cell Nevus Syndrome (BCNS) and Nevoid Basal Cell Carcinoma Syndrome (NBCCS).

About High Frequency Basal Cell Carcinoma (HF-BCC)

High Frequency BCC, like Gorlin Syndrome, is a rare disease which is characterized by the development of an abnormally high number of BCCs. Unlike patients with Gorlin Syndrome, patients with HF-BCC are not born with a germline PTCH1 mutation and do not suffer from the other systemic manifestations of Gorlin Syndrome. The standard of care for patients with HF-BCC is surgery.

About PellePharm

Founded by world leaders in hedgehog pathway signaling, PellePharm, a BridgeBio company, is committed to targeting rare forms of basal cell carcinoma, including Gorlin Syndrome and High Frequency Basal Cell Carcinoma (HF-BCC), at their source. PellePharm’s mission is to improve the quality of life for those suffering from Gorlin Syndrome and HF-BCC by providing an easy-to-use topical gel that could potentially reduce the need for regular, painful and disfiguring surgeries. Patidegib topical gel is a first-in-class topical formulation of a proprietary hedgehog inhibitor.

BridgeBio and Eidos Present Data from Phase 2 Open Label Extension Suggesting Long-term Tolerability of AG10 and Stabilization of Transthyretin Amyloid Cardiomyopathy Disease Measures

AG10 was Well Tolerated with Median 65 Weeks Follow-up since Phase 2 Initiation

Rates of All-Cause Mortality (Including Either Death or Cardiac Transplantation, 8.5%) and Cardiovascular Hospitalization (25.5%) Observed in Exploratory Analysis Were Lower than Rates Observed in Placebo-treated Participants in the ATTR-ACT Study

Near-complete Stabilization of TTR Maintained in Participants Throughout Duration of Study

Serum TTR levels, a Prognostic Indicator of Survival in ATTR-CM Patients, Were Elevated and Maintained in the Normal Range Throughout the Study Duration

Cardiac Biomarkers and Echocardiographic Parameters Were Stable Throughout Trial Duration

Presentation from AHA 2019 Scientific Sessions Available on Company Websites (eidostx.com and bridgebio.com) 

San Francisco, November 16, 2019 — BridgeBio Pharma, Inc. (BridgeBio) (Nasdaq:BBIO) and Eidos Therapeutics, Inc. (Eidos) (Nasdaq:EIDX), today presented positive data from the companies’ ongoing Open Label Extension (OLE) of the Phase 2 clinical trial studying AG10 in patients with symptomatic transthyretin (TTR) amyloidosis cardiomyopathy (ATTR-CM). ATTR-CM is a progressive and fatal disease that is an under recognized cause of heart failure. The data were presented in a late-breaking featured science oral presentation at the American Heart Association (AHA) Scientific Sessions in Philadelphia, Pennsylvania.

Study participants received 800mg of AG10 twice daily during the OLE and were followed for a median of 65 weeks since Phase 2 initiation. AG10 treatment was generally well-tolerated and resulted in near-complete TTR stabilization as measured using established ex vivo assays. Lower rates of mortality (death or cardiac transplantation) and cardiovascular-related hospitalizations were observed in AG10 Phase 2 OLE participants than were reported in a similar population of ATTR-CM patients who received placebo for 15 months in the ATTR-ACT study. Cardiac biomarkers and echocardiographic parameters were stable in patients treated with AG10 in the Phase 2 OLE.

“This update from our Phase 2 OLE demonstrated continued tolerability of AG10 in patients with advanced ATTR-CM. We also observed meaningfully lower rates of mortality and cardiovascular hospitalizations than what would be expected for untreated ATTR-CM patients with similar disease severity,” said Jonathan Fox, M.D., PhD., FACC, president and chief medical officer of Eidos. “These encouraging data continue to support the development of AG10 as a potentially best-in-class treatment for ATTR-CM patients.”

AG10 Phase 2 Open Label Extension Results

The ongoing OLE study enrolled 47 of 49 participants (96%) from the 28-day randomized, placebo-controlled, Phase 2 study of AG10 in ATTR-CM patients with New York Heart Association (NYHA) Class II or III symptoms. Interim analysis of the ongoing study was completed on August 31, 2019 in conjunction with annual regulatory reporting and review, at which time 41 participants remained in the study. Three (6.4%) participants in the OLE had died, two due to disease progression and one due to cervical cancer. Three (6.4%) additional patients enrolled in the study had discontinued treatment, including one participant who underwent cardiac transplantation for their disease.

–          Adverse events reported in the OLE study were generally consistent with the underlying ATTR-CM disease state and no safety signals of potential clinical concern were associated with the administration of AG10 in the study. Forty-six (97.9%) patients experienced a treatment-emergent adverse event reported during the study, with falls, congestive cardiac failure, dyspnea, and acute kidney injury the most commonly reported adverse events. Nineteen (40.4%) participants experienced a treatment-emergent serious adverse event reported during the study, with congestive cardiac failure (10.6%) and acute kidney injury (8.5%) the most commonly reported serious adverse events.

–          The rate of all-cause mortality (including either death or cardiac transplantation, 8.5%) and cardiovascular-related hospitalizations (25.5%) observed in an exploratory analysis of participants in this study following a median of 15 months since Phase 2 initiation were lower than those observed at 15 months in placebo-treated patients in the ATTR-ACT study (all-cause mortality including death or cardiac transplantation, 15.3%; cardiovascular-related hospitalizations, 41.8%).

–          Stabilization of TTR, as measured using established ex vivo assays, was maintained >90% on average at all study visits in actively treated patients.

–          Serum TTR levels, a prognostic indicator of survival in a published cohort of wild-type ATTR-CM patients, were elevated upon AG10 treatment and were maintained in the normal range throughout the study duration. Mean serum TTR levels were increased from baseline by 39% and 56% in wild-type and variant-carrying ATTR-CM patients, respectively, at OLE Visit Day 180.

–          Cardiac biomarkers and echocardiographic parameters were stable during the OLE study. NT-proBNP and TnI were unchanged throughout the course of the study. Echocardiographic parameters, including left ventricular mass and left ventricular stroke volume index, were unchanged during the study.

The presentation of the Phase 2 open label extension data from the American Heart Association (AHA) Scientific Sessions will be available on the company website (eidostx.com and bridgebio.com).

A Phase 3 study of AG10 in ATTR-CM patients (ATTRibute-CM) is currently ongoing. In Part A of the study, change in six-minute walk distance at 12 months will be compared between active treatment and placebo groups as the first registrational primary endpoint. In Part B, all-cause mortality and frequency of cardiovascular-related hospitalizations will be compared between treatment and control groups at 30 months total duration. In Part B, concomitant use of therapies indicated for the treatment of ATTR-CM may be allowed. The study is enrolling at 44 sites across six countries and enrollment for Part A is now projected to complete in the second half of 2020, with top-line data expected in 2021.

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 randomized, placebo-controlled 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. The open label extension of this Phase 2 study identified no safety signals of potential clinical concern associated with administration of AG10 15 months after study initiation. In an exploratory analysis, lower rates of all-cause mortality (including death and cardiac transplantation) and cardiovascular hospitalizations were observed in study participants than in placebo-treated ATTR-CM patients in the ATTR-ACT study. Cardiac biomarkers and echocardiographic parameters were stable in the AG10 Phase 2 OLE.

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. 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 at 30 months. In addition, Eidos plans to initiate a Phase 3 study of AG10 in ATTR polyneuropathy (ATTR-PN) in Q1 2020.

About transthyretin amyloidosis (ATTR)

There is significant medical need in transthyretin amyloidosis (ATTR) given the large patient population and limited 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 estimated to be at least 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 Reports Third Quarter 2019 Financial Results and Highlights Portfolio Progress

-Multiple clinical and pre-clinical milestones achieved across the BridgeBio portfolio

-Delivered pipeline growth with the addition of BBP-418 for limb-girdle muscular dystrophy type 2i

-Ended quarter with $446.1 million in cash, cash equivalents and marketable securities, excluding Eidos

Recent Highlights:

  • BBP-831 – FGFR1-3 inhibitor for achondroplasia: Initiated PROPEL, a prospective observational study in children with achondroplasia, the most common genetic form of short stature (NCT04035811). The study will establish annualized growth velocity (AGV) for each child over a minimum period of six months. PROPEL is designed to provide baseline measurements for children who enroll in PROPEL2, a Phase 2 study of low-dose infigratinib in achondroplasia which is on track to start in 2020. Additionally, in October 2019, new preclinical data supporting tolerability and efficacy of infigratinib in the mouse model of achondroplasia were reported at the American Society of Human Genetics conference (link to poster).
  • BBP-870 – cPMP replacement therapy for MoCD type A: Presented natural history study data at the Society of Inborn Errors of Metabolism Conference (link to poster) in September. These data suggest an urgent need for new therapies in molybdenum cofactor deficiency (MoCD) type A, an often-fatal rare genetic disease, and will be a critical component of the planned new drug application.
  • BBP-812 – Gene therapy candidate for Canavan disease: Opened a natural history study in Canavan disease (treatcanavan.com). Presented preclinical data (link to poster) demonstrating intravenous (IV) dosing of BridgeBio’s experimental therapy for Canavan disease (BBP-812) achieved broad central nervous system delivery; the IV approach is much less invasive compared to intrathecal or intracerebroventricular alternatives.
  • BBP-631 Gene therapy candidate for CAH: Presented preclinical update (link to poster) for gene therapy candidate BBP-631 in congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency wherein IV dosing of non-human primates with BBP-631 resulted in durable delivery and expression of the gene product to the adrenal tissue.
  • BBP-398 – SHP2 inhibitor for treatment-resistant cancer: Presented data (link to poster) highlighting the discovery and preclinical efficacy of BBP-398, a potent and selective SHP2 inhibitor, which is currently being prepared for the submission of an IND in 2020 for evaluation in RTK-driven cancer.
  • BBP-265 (AG10) – TTR stabilizer for ATTR: Granted Alexion Pharmaceuticals, Inc. an exclusive license to develop and commercialize AG10 in Japan for an upfront payment of $25 million and an equity investment of $25 million.
  • Pipeline growth: Announced addition of a new asset, BBP-418, to the pipeline. BBP-418 is a substrate supplementation therapy for the treatment of limb-girdle muscular dystrophy type 2i and is in IND-enabling studies. This condition affects an estimated 7,000 patients in the United States and European Union with no currently approved therapies.
  • Organizational growth: Added two new members to the senior leadership team. Brian Stolz joined as Chief Operating Officer of BridgeBio. Mr. Stolz most recently held the position of Chief People Officer at Activision Blizzard. Yi Ching Yau joined as Chief Accounting Officer of BridgeBio. Prior to joining BridgeBio, Ms. Yau served as the VP of Finance at Nektar Therapeutics.

Upcoming Milestones:

  • BBP-265 (AG10) – TTR stabilizer for ATTR: Plan to present interim analysis of the ongoing Phase 2 open label extension study (NCT03536767) of AG10 in patients with TTR amyloid cardiomyopathy, an inherited form of heart failure, at the American Heart Association 2019 Scientific Sessions in a Late-Breaking Featured Science Oral Presentation. A Phase 3 study of AG10 in ATTR-PN (ATTRibute-PN) is on track to begin in the first quarter of 2020.
  • BBP-870 – cPMP replacement therapy for MoCD type A: On track to initiate a rolling new drug application submission for our first-in-class therapy for molybdenum cofactor deficiency (MoCD) type A, BBP-870, by the end of 2019.
  • BBP-589 – COL7A protein replacement therapy for recessive dystrophic epidermolysis bullosa: Plan to share topline data from the ongoing Phase 1/2 study (NCT03752905) during 2020.
  • BBP-831 (infigratinib) – FGFR1-3 inhibitor for FGFR2+ cholangiocarcinoma: Plan to complete enrollment of the ongoing pivotal Phase 2 study (NCT02150967) in second line cholangiocarcinoma (bile duct cancer) and present updated results at a major oncology meeting in 2020. Remain on track to submit new drug application for FDA approval in 2020.

Third Quarter 2019 Financial Results:

 Cash, Cash Equivalents and Marketable securities

Consolidated cash, cash equivalents and marketable securities, excluding restricted cash, totaled $611.9 million as of September 30, 2019.  Excluding Eidos, BridgeBio’s cash balance as of September 30, 2019 was $446.1 million compared to $162.4 million as of June 30, 2019.  The net change in cash balance of $283.7 million reflects net proceeds received from BridgeBio’s initial public offering of $368.7 million, offset by the repurchase of a non-controlling interest for $26.4 million and approximately $58.6 million primarily for operating expenses.

BridgeBio Pharma Gene Therapy Subsidiaries Present Data Demonstrating Potential in Two Rare Disease Indications at the European Society of Gene and Cell Therapy Conference

  • Preclinical data shows promise for gene therapy candidates for congenital adrenal hyperplasia due to 21-hydroxylase deficiency (BBP-631) and Canavan disease (BBP-812)
  • Natural history clinical study for Canavan disease is currently enrolling
  • IND submissions for both gene therapy product candidates anticipated in 2020

SAN FRANCISCO – October 22, 2019 – BridgeBio Pharma, Inc. (NASDAQ:BBIO) today announced that promising preclinical data from two of its gene therapy-focused subsidiaries – Adrenas Therapeutics and Aspa Therapeutics – will be presented at the European Society of Gene and Cell Therapy (ESGCT) Conference, occurring in Barcelona from October 22 to 25. In addition, the company announced that Aspa Therapeutics is currently conducting a natural history study in children with Canavan disease, CANinform.

Experimental Gene Therapy for Congenital Hyperplasia Shows Durable Transgene Expression

Researchers from BridgeBio subsidiary Adrenas Therapeutics presented new preclinical results from gene therapy candidate BBP-631 in a poster entitled “Durable CYP21A2 Gene Therapy in Non-Human Primates for Treatment of Congenital Adrenal Hyperplasia.” Throughout the study, a total of 20 non-human primates (NHPs) were treated with BBP-631 at one of three intravenous (IV) doses. Vector copy number and transgene mRNA expression in the adrenal glands were analyzed at 4 and 12 weeks post-dosing in the low- and medium-dose arms and at 12 and 24 weeks post-dosing in the high-dose arm. No dose-related adverse events were observed at any of the doses tested at any time point.

Overall, treatment with BBP-631 resulted in high vector copy number (VCN) and mRNA expression in the adrenal gland, suggesting strong tropism and uptake of BBP-631 for the adrenal gland. In the high-dose arm, VCNs were maintained between 12 and 24 weeks. Furthermore, mRNA levels increased between 4 and 12 weeks for the medium dose arm and were consistent between 12 and 24 weeks for the high dose arm. Researchers also saw dose-dependent increases in both VCNs and mRNA levels across the three doses tested.

“Durable expression of a vector in adrenal tissue has presented challenges for the development of gene therapies for adrenal indications,” said Clayton Beard, Ph.D., Senior Vice President, Research and Development at BridgeBio Gene Therapy. “The observed maintenance of the BBP-631 AAV5 vector for as long as 24 weeks in NHPs represents an important step in validating a gene therapy approach to treat 21-hydroxylase deficiency, and we anticipate filing our IND for this indication in 2020.”

Canavan Disease Experimental Therapy Amenable to IV Delivery

In a poster entitled “A Route of Administration Study of BBP-812, an AAV9-based Gene Therapy for the Treatment of Canavan Disease, in Juvenile Cynomolgus Macaques,” scientists from Aspa Therapeutics examine the uptake of and resulting DNA and mRNA expression for BBP-812, an experimental AAV9 vector, in three different administration routes: intravenous (IV), intrathecal (IT) or intracerebroventricular (ICV). Biodistribution of vector genomes and of transgene mRNA was evaluated throughout the central nervous system (CNS) at both 3 and 8 weeks post-administration. No dose-related adverse events were observed at any tested doses at either time period.

Using an IV route of administration, vector copy number and mRNA expression were not only detected broadly throughout the brain and spinal cord, but were generally detected at levels higher than when administered ICV or IT.

“Developing therapies for diseases like Canavan presents particular delivery challenges – namely getting the therapy into the central nervous system,” said Adam Shaywitz, M.D., Ph.D., Chief Medical Officer at BridgeBio Gene Therapy. “In this preclinical study, we observed that broad CNS delivery of our vector is possible using an IV route, which is far less invasive than the IT or ICV routes and therefore points to IV as the preferred route of administration in our clinical program for Canavan disease.”

Aspa Therapeutics is currently enrolling a natural history study of Canavan disease called CANinform. Interested individuals can find information about the study at TreatCanavan.com.

About Adrenas Therapeutics

Adrenas Therapeutics is a BridgeBio Pharma subsidiary developing a gene therapy treatment for congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, a rare genetic disorder which affects the ability of the adrenal glands to properly function. People with CAH have an impaired ability to produce the hormone cortisol, which can result in life-threatening adrenal crises and significant morbidity throughout life.

About Aspa Therapeutics

Aspa Therapeutics is a BridgeBio Pharma subsidiary focused on developing a gene therapy to treat Canavan disease, an extremely rare genetic disease caused by an inherited mutation of the ASPA gene wherein children affected experience lack of head control, lack of muscle tone (often resulting in floppiness or spasticity) and seizures.

QED and Parent Company BridgeBio Announce Preclinical Data Supporting Tolerability and Activity of Low-dose Infigratinib in Treating Achondroplasia

Data presented at the American Society of Human Genetics (ASHG) 2019 Annual Meeting

  • Infigratinib showed improvements in nine measures of bone development in the Fgfr3Y367C/+ mouse model of achondroplasia at a low dose
  • Observational study (The PROPEL Trial) is currently enrolling children age 2.5-10 years and planned submission of an investigational new drug application remains on track for 2020

SAN FRANCISCO – October 17, 2019 – QED Therapeutics, Inc. and parent company BridgeBio Pharma, Inc. (NASDAQ: BBIO) announced today the presentation of preclinical data supporting the potential of low-dose infigratinib for the treatment of achondroplasia. The data were presented during the ASHG 2019 Annual Meeting in a poster entitled “Low dose, daily or intermittent administration of infigratinib (BGJ398), a selective FGFR inhibitor, as treatment for achondroplasia in a preclinical mouse model.” 

Achondroplasia is the most common cause of dwarfism and is caused by mutation of the gene for fibroblast growth factor receptor 3 (FGFR3). FGFR3 has been shown to be crucial for the process of bone elongation.1,2 Infigratinib, an investigational agent, binds to FGFR3 and has been previously shown to increase bone growth in preclinical mouse models of achondroplasia.3 The data presented today showed a positive dose-response relationship between infigratinib and bone growth.

“Observing a dose-response relationship is an important step in developing infigratinib as a therapy for achondroplasia,” said Laurence Legeai-Mallet, Ph.D., head of research team at Imagine Institute, INSERM U1163, Université de Paris, who led the research. “We also observed better organization within the hypertrophic zone of the growth plate, which is responsible for bone formation and elongation, indicating that a low dose of infigratinib had a positive effect.”

The preclinical study used a dwarf mouse model (Fgfr3Y367C/+), which mimics achondroplasia. In each of the three dose groups, treatment with infigratinib led to an increase in all nine measures of bone size studied compared to the control group (See figure). At the highest dose examined (0.5 mg/kg/day), treatment with infigratinib demonstrated a statistically significant (P < 0.01) improvement in bone length of 7-14% in the upper limbs, 10% to 17% in the lower limbs and 12% in the foramen magnum (an opening at the base of the skull). No apparent toxicity of infigratinib was noted in this study.

“We are encouraged by this preclinical data supporting the ability of a low dose, or even intermittently dosed, infigratinib to increase the length of the limbs as well as other bones in the skeleton. In particular, we believe the increase in foramen magnum size has significant implications, given that narrowing of this area of the skull can, in some cases, cause cervical spinal cord compression in achondroplastic children,” said Susan Moran, M.D., M.S.C.E., chief medical officer at QED. “These data support our decision to submit an investigational new drug application to the U.S. Food and Drug Administration and initiate a clinical trial in 2020 to investigate the potential to treat children with achondroplasia with infigratinib at doses 10 to 100 times lower than used in oncology indications.”

BridgeBio Pharma Terminates Merger Process With Its Subsidiary Eidos Therapeutics

Agreement Not Reached Between BridgeBio Pharma and Special Committee of Eidos Therapeutics Independent Directors; BridgeBio No Longer Pursuing Acquisition

PALO ALTO – October 14, 2019 – BridgeBio Pharma, Inc. (NASDAQ: BBIO), a clinical-stage biopharmaceutical company focused on genetic diseases, announced today that it was unable to come to an agreement with the Special Committee formed by its subsidiary Eidos Therapeutics (NASDAQ: EIDX), a clinical-stage biopharmaceutical company developing AG10 for the treatment of transthyretin amyloidosis (ATTR), to acquire the outstanding common stock of Eidos that BridgeBio does not already own (approximately 34% of Eidos’s outstanding shares).

Subsequent to an initial offer of 1.3 BridgeBio shares for each Eidos share, the offer was raised twice, resulting in a final offer equivalent to 1.5 BridgeBio shares for each Eidos share with an option for Eidos shareholders to receive a portion of that consideration in cash. Eidos shareholders were to have three options to receive their consideration: all-stock, mixed consideration of cash and stock, or all-cash subject to proration such that the cash portion of the transaction would not exceed approximately $110 million. The cash consideration was to have been funded by BridgeBio with the use of acquisition financing, and was therefore to have had a neutral-to-positive impact upon BridgeBio’s runway post-close.

“We appreciate the hard work of the Eidos Special Committee in evaluating our proposal,” said Brian Stephenson, Ph.D., CFA, chief financial officer of BridgeBio. “At BridgeBio, we work hard to balance opportunities for doubling down on attractive pipeline programs with preserving our ability to pursue a diversified pipeline, as the latter characteristic is valued deeply by many of our investors. We continue to believe strongly in AG10, of which we retain approximately 66% ownership, but we feel that beyond our final offer there are superior ways for us to deploy capital, both in and outside of our pipeline, to generate benefits for patients and returns for our investors. Going forward, we will continue to focus on creating value for patients and investors alike by efficiently allocating capital to high-return genetic disease projects where the science supports advancing therapeutic candidates as rapidly as possible.”

“With this process now behind us, we will return to operating BridgeBio and Eidos as two companies that share the sole focus of bringing important medicines to patients with genetic disease,” said Neil Kumar, Ph.D., founder and chief executive officer of BridgeBio and chief executive officer of Eidos. “BridgeBio will continue to empower Eidos with critical leadership and infrastructure across the commercial, clinical operations, and executive functions, while Eidos will remain laser-focused on getting AG10, our potentially best-in-class stabilizer for ATTR-CM, to patients. I thank the Special Committee for its hard work and look forward to continuing our efforts around the Phase 3 trial for AG10 and the analysis of data from our Phase 2 Open Label Extension. Eidos and AG10 are a significant part of who we are at BridgeBio, having been part of our plan since we founded the company. We remain incredibly excited about the program and its potential for patients with ATTR cardiomyopathy.”

Ivy Brain Tumor Center and BridgeBio Subsidiary QED Therapeutics Announce Collaboration to Advance Cancer Research and Treatment Options

Preclinical study designed to test investigational agent infigratinib for the treatment of glioblastoma.

(PHOENIX, AZ — Sept. 24, 2019) — The Ivy Brain Tumor Center at Barrow Neurological Institute, today announced a new collaboration with QED Therapeutics, Inc., a subsidiary of BridgeBio Pharma, Inc., to investigate the FGFR1-3 tyrosine kinase inhibitor, infigratinib, for the treatment of glioblastoma (GBM).  With the goal of addressing unmet medical needs for those affected by malignant brain cancer, this collaboration will focus on targeting FGFR (fibroblast growth factor receptor) genetic alterations that have been shown to spur growth in malignant tumors.

“Five to seven percent of glioblastoma patients’ tumors are driven by FGFR signaling,” said Dr. Nader Sanai, director of the Ivy Brain Tumor Center. “We believe our collaboration with QED Therapeutics will enable us to test how FGFR-driven GBM tumors respond to infigratinib. If proven effective, we then intend to move forward new combined drug strategies incorporating this target.”

In the preclinical studies, the Ivy Center will employ orthotopically implanted, well-characterized FGFR3 fusion patient-derived xenograft models. This is intended to allow the team to further explore the extent to which the drug crosses the blood-brain barrier and what activity it has in the brain.

“We believe the work we are undertaking with the Ivy Center will provide critical insight to shape our clinical development strategy for this disease,“ said Susan Moran, M.D., M.S.C.E., chief medical officer of QED Therapeutics. “Our hope is that infigratinib will become the backbone of new combination therapies to treat patients with glioblastoma.”

Infigratinib is an orally administered, FGFR1-3 selective tyrosine kinase inhibitor. QED Therapeutics has observed activity that appears to be meaningful in clinical trials for cancers that are driven by errors in the FGFR genes. These include chemotherapy-refractory cholangiocarcinoma with FGFR2 fusions and advanced urothelial carcinoma with FGFR3 genetic alterations.

“The intricacies of the brain have posed significant challenges for brain cancer research and the development of therapies,” said Gary Li, head of translational medicine at QED Therapeutics. “We believe collaborating with the Ivy Brain Tumor Center will enable us to move swiftly and further translational research that we hope will unlock the doors to effective treatment options.”

About Ivy Brain Tumor Center

Ivy Brain Tumor Center at the Barrow Neurological Institute in Phoenix, AZ is a non-profit translational research program that employs a bold, early-phase clinical trials strategy to identify new treatments for aggressive brain tumors, including glioblastoma.

Our lead investigational candidate is infigratinib (BGJ398), an orally administered, FGFR1-3 selective tyrosine kinase inhibitor that has shown activity that we believe to be meaningful in clinical measures such as overall response rate 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. We plan to conduct further clinical trials to evaluate the potential for infigratinib to treat patients with other FGFR-driven tumor types and rare disorders.
