RESEARCH TRIANGLE PARK, N.C., Nov. 03, 2023 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced updates from its drug discovery process and additional therapies from its pipeline that the company will highlight at a Research and Development (R&D) Day today at 1:00p ET at the company’s Discovery Center of Excellence in Birmingham, Alabama. A live webcast of the event will be available online in the investors section of the company website at www.biocryst.com.
“The success we are achieving with ORLADEYO demonstrates that when we deliver a first-in-class or best-in-class medicine, we can change patients’ lives. The focus of our discovery efforts is to leverage our 30-plus years of experience to bring more first-in-class or best-in-class medicines to patients living with complement-mediated and other rare diseases. The team is excited to share our approach, and our expanded pipeline of new programs, at our R&D Day,” said Jon Stonehouse, president and chief executive officer of BioCryst.
“We have significantly diversified our pipeline and we continue to be disciplined around decisions to invest further only when a program meets the high bar we have set of first-in-class or best-in-class. We believe the combination of ORLADEYO, our exciting pipeline and our financial strength, position us to continue to make a big difference in patients’ lives, and that leads to sustainable growth for years to come,” Stonehouse added.
PROGRAM UPDATES AT R&D DAY
BCX17725 — Fusion Protein KLK5 Inhibitor for treatment of Netherton syndrome
Netherton syndrome is a rare, lifelong genetic disorder that often presents in neonates or infancy. The disease is caused by the deficiency of a natural inhibitor (SPINK5) of KLK5, a serine protease responsible for regulating skin shedding. Patients may have red, scaly and inflamed skin and susceptibility to recurrent immune reactions. Netherton syndrome can be life threatening, especially during infancy when patients are vulnerable to dehydration and recurrent infections. Currently, there is no approved treatment for Netherton syndrome.
BCX17725 is a potent and selective investigational fusion protein KLK5 inhibitor designed to provide best-in-class, potentially disease-modifying treatment for people with Netherton syndrome.
At the R&D Day, the company plans to showcase how it applied its structure-guided drug design expertise to create this fusion protein, and share nonclinical data showing distribution of the molecule to the epidermis following intraperitoneal (IP) administration.
The company expects to begin clinical trials of BCX17725 in 2024.
Avoralstat — Plasma kallikrein inhibitor combined with Clearside’s SCS Microinjector® for treatment of diabetic macular edema (DME) in patients with sub-optimal response to anti-VEGF therapy
DME is the most common cause of vision loss in individuals with diabetes and at least one-third of patients have persistent DME despite anti-VEGF therapies, which are administered via monthly injection. Data have shown that elevated plasma kallikrein may be a cause of non-response to anti-VEGF therapy.
Delivering avoralstat directly into the suprachoroidal space of the eye with the SCS Microinjector could allow avoralstat to inhibit plasma kallikrein at the sites of edema formation in DME disease, the retinal and choroidal vascular endothelium. Avoralstat has low solubility, which supports evaluation of a suspension depot formulation for ophthalmic injection. With low solubility, the drug could persist in the eye at the site of disease for a long duration, resulting in less frequent injections.
At the R&D Day, the company plans to present nonclinical data showing high levels of avoralstat are maintained in the eye for at least 90 days following suprachoroidal injection.
Avoralstat was previously studied in an oral formulation in a phase 3 trial in patients with HAE. In the HAE clinical trial program in 276 individuals, avoralstat was safe and well tolerated with an adverse event profile similar to placebo.
The company believes that combining a potent, low-solubility kallikrein inhibitor that has a pre-existing systemic safety database with the only FDA-approved approach to access the suprachoroidal space provides the potential to deliver a best-in-class medicine for DME patients inadequately controlled with anti-VEGF therapy.
The company expects to conduct formulation and nonclinical work in 2024 and begin clinical trials in 2025.
Oral C5 Inhibitor — Treatment of generalized myasthenia gravis (and other complement-mediated diseases)
Generalized myasthenia gravis (gMG) is a chronic autoimmune, neuromuscular disease that causes muscle weakness that worsens after periods of activity. It is caused when autoantibodies (anti-AChR) form that activate the complement system, causing the immune system to attack the neuromuscular junctions, or connections between muscles and nerves.
BioCryst is developing a first-in-class oral C5 inhibitor that could be the first targeted oral therapy with competitive efficacy to currently approved injected and infused anti-C5 therapies, such as eculizumab and ravulizumab. A drug with this profile could enable gMG patients to switch from infused therapy and address their disease earlier in the treatment paradigm.
At the R&D Day, the company plans to show data from the nonclinical program highlighting the potency, selectivity, oral bioavailability and pharmacokinetic parameters of its lead molecule candidates.
The company expects to complete lead optimization in 2024 and begin clinical trials in 2025.
Bifunctional complement inhibitor — simultaneously inhibiting multiple complement pathways to better address complex renal complement-mediated diseases like IgAN and lupus nephritis
BioCryst is developing a bifunctional complement inhibitor anti-C2 monoclonal antibody that also inhibits the alternative pathway. This investigational candidate could be a first-in-class combined inhibitor of the classical, lectin and alternative pathways of the complement system to best treat complex renal complement-mediated diseases like progressive IgAN and lupus nephritis, which are influenced by multiple complement pathways.
At the R&D Day, the company plans to share nonclinical data demonstrating the strong potency and ability of the company’s bifunctional monoclonal antibody to inhibit multiple pathways in the complement system.
The company expects to select a lead molecule in 2024 and begin clinical trials in 2025.
Oral C2 Inhibitor — classical and lectin pathway complement inhibitor to treat autoimmune hemolytic anemias, including cold agglutinin disease (CAD) and warm autoimmune hemolytic anemia (wAIHA)
The limited approved options for treating diseases like CAD and wAIHA are injectable or infused. An oral C2 inhibitor from BioCryst would be first-in-class and allow patients to switch from infused therapy and address their disease earlier in the treatment paradigm.
Inhibiting C2 could decrease red cell destruction (hemolysis) in autoimmune hemolytic anemias by blocking the classical and lectin pathways.
At the R&D Day, the company plans to describe the data targets for potency, selectivity and bioavailability of its lead compounds.
The company expects to select a lead molecule in 2025.
BCX10013 — Once-daily, oral Factor D inhibitor for renal complement-mediated diseases
BCX10013 is a potent and selective Factor D inhibitor that, if it achieves comparable or superior efficacy to twice-daily alternative pathway inhibitors in development, would offer a best-in-class profile as the first and only oral alternative pathway inhibitor with once-daily dosing.
At the R&D Day, the company plans to present data from the recently completed 160 mg cohort of its multiple ascending dose healthy volunteer trial which highlights the strength and duration of alternative pathway suppression achieved at this dose level, supporting once-daily clinical dosing.
The company expects to report data from its ongoing proof-of-concept trial in 2024.
ORLADEYO® (berotralstat) — Pediatric formulation for the prevention of HAE attacks in patients 2 to <12 years of age
ORLADEYO, the first oral, once-daily plasma kallikrein inhibitor, is approved in the United States and many global markets for people with HAE age 12 and older. The ongoing APeX-P clinical trial is assessing an oral granule formulation of ORLADEYO in pediatric HAE patients who are 2 to <12 years of age.
Approximately 40 percent of HAE patients have their first attack by five years of age and there are no current targeted oral therapies available for prophylaxis in children <12 years old.
The company expects to submit a U.S. supplemental new drug application for the pediatric use of ORLADEYO in 2025.
2024 R&D Investment Guidance
The company’s focus on rigorous best-in-class or first-in-class investment criteria, and the lower investment cost of earlier stage programs, are expected to limit 2024 R&D spending to a total of between $230 million and $240 million across all programs. This represents an increase from projected 2023 R&D spending of $25 million to $35 million, and represents a decrease from R&D spending in 2022 of $13 million to $23 million. These numbers include non-cash stock compensation. At the R&D Day, the company will describe its disciplined approach to capital allocation.
