Current report

We are developing our investigational plasma kallikrein inhibitor, avoralstat, with Clearside Biomedical, Inc.’s SCS Microinjector®to deliver avoralstat to the back of the eye through the suprachoroidal space to treat patients with diabetic macular edema (“DME”). DME is an important cause of vision loss in diabetes and is due to leakage from the blood vessels in the retina. While current treatments focus on vascular endothelial growth factor (“VEGF”) inhibition, DME can develop from other mechanisms, such as the kallikrein-bradykinin pathway. This is supported by observations that many DME patients have an incomplete response to intravitreal anti-VEGF therapies that are administered every four to eight weeks. Avoralstat targets the kallikrein-bradykinin system on the retinal vascular endothelial cells and may result in less vascular leakage and less edema. Avoralstat, delivered to the suprachoroidal space as a depot formulation, is designed to provide high dose levels to the retinal vessels with long-lasting exposure, which could result in less frequent injections and a reduced burden on patients and the healthcare system.

Previous report

We are developing our investigational plasma kallikrein inhibitor, avoralstat, with Clearside Biomedical, Inc.’s SCS Microinjector®to deliver avoralstat to the back of the eye through the suprachoroidal space to treat patients with diabetic macular edema (“DME”). 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-vascular endothelial growth factor therapies, which are administered via monthly injection. Avoralstat, which was previously studied in an oral formulation in a phase 3 trial in patients with HAE, has high potency and low solubility, two characteristics we believe are important to achieving potential efficacy with reduced dosing frequency in the eye for DME patients.

Previous report

On February 19, 2024, we announced that the Italian Medicines Agency finalized reimbursement and recommended ORLADEYO for the routine prevention of recurrent attacks of HAE in eligible patients 12 years and older.

Previous report

Previous wording

We have built out our U.S. commercial infrastructure to support the launch and continued commercialization of ORLADEYO in the United States and are continuing to build our commercial infrastructure to support launches in other markets. Based on proprietary analyses of HAE prevalence and market research studies with HAE patients, physicians, and payors in the United States and Europe, and three full years of commercialization experience with ORLADEYO, we anticipate the global commercial market for ORLADEYO has the potential to reach a global peak of $1 billion in annual net ORLADEYO revenues. We expect approximately 80 percent of our revenue at peak to come from the United States. These expectations are subject to numerous risks and uncertainties that may cause our actual results, performance, or achievements to be materially different. There can be no assurance that our commercialization methods and strategies will succeed, or that the market for ORLADEYO will develop in line with our current expectations. See “Risk Factors—Risks Relating to Our Business—Risks Relating to Drug Development and Commercialization—There can be no assurance that our or our partners’ commercialization efforts, methods, and strategies for our products or technologies will succeed, and our future revenue generation is uncertain” in Part II, Item 1A of this report for further discussion of these risks.

Previous wording

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. 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 skin infections. 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.

Previous wording

Cost of product sales for the three months ended March 31, 2024 and 2023 was $1.3 million and $0.9 million, respectively. The increase in cost of product sales was primarily due to an increase in ORLADEYO sales in the current year period.

Current wording

Cost of product sales for the three months ended June 30, 2024 and 2023 was $1.7 million and $0.9 million, respectively. The increase in cost of product sales was primarily due to an increase in ORLADEYO sales in the current year period.

Previous wording

Research and development expenses decreased to $46.5 million for the three months ended March 31, 2024 from $48.4 million for the three months ended March 31, 2023, primarily due to a decrease in Factor D program expenses. This decrease in Factor D program expenses was primarily attributed to decreased spending on BCX10013 due to our plan to either out-license or discontinue late-stage development and commercialization, which was announced in January 2024, as well as the discontinuation of the BCX9930 program, which was announced in December 2022. These reductions to research and development expenses were partially offset by increased spending on berotralstat due to ORLADEYO label expansion and life cycle investments, such as our ongoing ORLADEYO pediatric trial, and increased spending on other research, preclinical and development costs. Other research, preclinical and development costs increased due to increased spending on BCX17725 for manufacturing costs and investigational new drug application-enabling activities and increased spending related to our other early-stage discovery programs.

Current wording

Research and development expenses decreased to $37.6 million for the three months ended June 30, 2024 from $51.2 million for the three months ended June 30, 2023, primarily due to a decrease in Factor D program expenses. The decrease in Factor D program expenses was primarily attributed to decreased spending on BCX10013 and the discontinuation of the BCX9930 program.

For the three months ended June 30, 2024, total revenues were $109.3 million as compared to $82.5 million for the three months ended June 30, 2023. The increase in total revenues was due to a $27.3 million increase in ORLADEYO net revenue, including royalties. The increase in ORLADEYO net revenue was partially offset by a decrease in other net revenues of $0.4 million due to a decrease in royalties for sales of peramivir.

Research and development expenses decreased to $84.1 million for the six months ended June 30, 2024 from $99.6 million for the six months ended June 30, 2023, primarily due to a decrease in Factor D program expenses. The decrease in Factor D program expenses was primarily attributed to decreased spending on BCX10013 and the discontinuation of the BCX9930 program. These reductions to research and development expenses were partially offset by increased spending on berotralstat due to our ongoing ORLADEYO pediatric trial, and increased spending on other research, preclinical and development costs. Other research, preclinical and development costs increased due to increased spending on BCX17725 and avoralstat for investigational new drug application-enabling activities and increased spending related to our other early-stage discovery programs.

Interest expense for the six months ended June 30, 2024 was $49.2 million compared to $56.3 million for the six months ended June 30, 2023. The decrease in interest expense was primarily due to the decrease in the effective interest rate related to the 2021 RPI Royalty Purchase Agreement (as defined in “Note 6—Royalty Financing Obligations—ORLADEYO and Factor D Inhibitors” in the Notes to Condensed Consolidated Financial Statements in Part I, Item 1 of this report), partially offset by an increase in interest expense associated with the interest accrued on the Tranche A Loan of $300.0 million under the Pharmakon Loan Agreement, which was funded on April 17, 2023.

For the six months ended June 30, 2024, income tax expense was $0.5 million compared to $1.4 million for the six months ended June 30, 2023. The decrease in income tax expense is primarily due to an increase in the amortization deduction related to capitalized research and development costs and the reversal of certain tax timing differences.
