—ORLADEYO net revenue expected to more than double in 2022 to no less than $250 million; Company expects ORLADEYO to become the market leader in HAE prophylaxis therapy with peak sales of $1 billion—

RESEARCH TRIANGLE PARK, N.C., Jan. 10, 2022 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced preliminary, unaudited ORLADEYO® (berotralstat) revenue for the fourth quarter and full year 2021 and provided new guidance for full year 2022 ORLADEYO net revenue and expected peak ORLADEYO sales.

“Following 12 months of a successful launch through a global pandemic, we have a clear picture of the continued commercial trajectory for ORLADEYO based on a very attractive product profile, leading to strong patient demand to switch from injectable therapies to our oral, once-daily medicine, with 70 percent patient retention through the first year. Building on our substantial 2021 patient base, we are confident that ORLADEYO will achieve no less than $250 million of net revenue in 2022 and that ORLADEYO will become the market leader as the most prescribed prophylactic therapy with peak sales of $1 billion,” said Jon Stonehouse, president and chief executive officer of BioCryst.

Fourth Quarter 2021 (Q4 2021) ORLADEYO Launch Dynamics

  • Preliminary, unaudited ORLADEYO net revenue in Q4 2021 was $45.6 million. Preliminary, unaudited ORLADEYO net revenue for full year 2021 (FY 2021) was $122 million.

  • New patient demand for ORLADEYO remains strong and consistent, with a similar number of new patients added in Q4 2021 as in each of the previous three quarters of the year. Patients switching from other prophylactic therapies and acute-only therapy continue to drive the launch. More than half of patients new to ORLADEYO since launch had a previous prophylactic medicine prior to ORLADEYO and most of the remainder were from acute-only treatment.

  • Most patients are well-controlled on ORLADEYO and remain on therapy. Approximately 70 percent of patients starting ORLADEYO, including those switching from injectable prophylaxis, remain on ORLADEYO in the first year.

  • ORLADEYO is now covered by all major payors and national and regional pharmacy benefit managers, which will lead to more patients being reimbursed quickly.

  • The ORLADEYO prescriber base continues to grow significantly. The number of new physicians prescribing ORLADEYO in Q4 2021 was similar to the number added in Q3 2021. In market research, 60 U.S. physicians, who treat an average of seven HAE patients each, reported that they expect to double their use of ORLADEYO, and that ORLADEYO will become their most prescribed prophylactic treatment in the next 12 months.

“We expect ORLADEYO revenues in 2022 to more than double in our second year of launch as we benefit from a full year of reimbursement and continued strong demand from patients and physicians. ORLADEYO is transforming the lives of HAE patients, which is why ORLADEYO is on a trajectory to become the market leader in HAE prophylaxis,” said Charlie Gayer, chief commercial officer of BioCryst.

Pipeline Update: BCX9930 Pivotal Trials in PNH Now Enrolling

BioCryst is currently enrolling patients in two global pivotal trials, REDEEM-1 and REDEEM-2, with the company’s oral Factor D inhibitor, BCX9930 (500 mg bid), in patients with paroxysmal nocturnal hemoglobinuria (PNH). The company also has begun screening patients in a proof of concept (PoC) basket trial of BCX9930 (500 mg bid) in patients with C3 glomerulopathy (C3G), IgA nephropathy (IgAN) and primary membranous nephropathy (PMN).

BioCryst plans to further advance and expand its Factor D program over the next two years by achieving the following:

  • Complete and report data from REDEEM-1 and REDEEM-2
  • Prepare to submit regulatory approval filings in PNH
  • Complete the renal PoC basket trial and advance to pivotal trials in C3G, IgAN and PMN
  • Commence PoC trials in other complement-mediated diseases

“Following the discovery, development and commercialization of ORLADEYO, the BioCryst team plans to repeat this success as we leverage our platform to bring new oral medicines to patients suffering from other rare diseases. BCX9930 is especially exciting because the clinical data we have reported so far provides confidence that we can help patients in PNH, and across many complement-mediated diseases, with this pipeline in a molecule,” said Dr. Helen Thackray, chief research and development officer of BioCryst.

About ORLADEYO® (berotralstat)
ORLADEYO® (berotralstat) is the first and only oral therapy designed specifically to prevent attacks of hereditary angioedema (HAE) in adult and pediatric patients 12 years and older. One capsule of ORLADEYO per day works to prevent HAE attacks by decreasing the activity of plasma kallikrein.

U.S. Indication and Important Safety Information

INDICATION
ORLADEYO® (berotralstat) is a plasma kallikrein inhibitor indicated for prophylaxis to prevent attacks of hereditary angioedema (HAE) in adults and pediatric patients 12 years and older.

Limitations of use
The safety and effectiveness of ORLADEYO for the treatment of acute HAE attacks have not been established. ORLADEYO should not be used for the treatment of acute HAE attacks. Additional doses or dosages of ORLADEYO higher than 150 mg once daily are not recommended due to the potential for QT prolongation.

IMPORTANT SAFETY INFORMATION
An increase in QT prolongation was observed at dosages higher than the recommended 150 mg once-daily dosage and was concentration dependent.

The most common adverse reactions (≥10 percent and higher than placebo) in patients receiving ORLADEYO were abdominal pain, vomiting, diarrhea, back pain, and gastroesophageal reflux disease.

A reduced dosage of 110 mg taken orally once daily with food is recommended in patients with moderate or severe hepatic impairment (Child-Pugh B or C) and in patients taking chronically administered P-glycoprotein (P-gp) or breast cancer resistance protein (BCRP) inhibitors (eg, cyclosporine).

Berotralstat is a substrate of P-gp and BCRP. P-gp inducers (eg, rifampin, St. John’s wort) may decrease berotralstat plasma concentration, leading to reduced efficacy of ORLADEYO. The use of P-gp inducers is not recommended with ORLADEYO.

ORLADEYO at a dose of 150 mg is a moderate inhibitor of CYP2D6 and CYP3A4. For concomitant medications with a narrow therapeutic index that are predominantly metabolized by CYP2D6 or CYP3A4, appropriate monitoring and dose titration is recommended. ORLADEYO at a dose of 300 mg is a P-gp inhibitor. Appropriate monitoring and dose titration is recommended for P-gp substrates (eg, digoxin) when coadministering with ORLADEYO.

The safety and effectiveness of ORLADEYO in pediatric patients <12 years of age have not been established.

There are insufficient data available to inform drug-related risks with ORLADEYO use in pregnancy. There are no data on the presence of berotralstat in human milk, its effects on the breastfed infant, or its effects on milk production.
