Press Release Details

RESEARCH TRIANGLE PARK, N.C., Feb. 22, 2022 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced the enrollment of the first patient in the RENEW proof-of-concept basket study with its oral Factor D inhibitor, BCX9930, in patients with C3 glomerulopathy (C3G), immunoglobulin A nephropathy (IgAN) and primary membranous nephropathy (PMN).

RENEW is an open-label, multicenter, proof-of-concept study designed to evaluate the safety, tolerability and therapeutic potential of BCX9930 (500 mg bid) administered for 24 weeks in approximately 42 adult patients (14 patients in each disease) with either C3G, IgAN or PMN. All patients will be enrolled into one of three parallel study cohorts, based on confirmation of diagnosis and disease activity in a recent kidney biopsy, and will receive BCX9930 for the 24-week treatment period. The primary endpoint of RENEW is percent change from baseline in 24-hour urine protein-to-creatinine ratio (uPCR), as assessed at week 24. For more information about RENEW, visit ClinicalTrials.gov and search NCT number NCT05162066.

“There are currently no targeted treatments available for patients living with these rare renal diseases, which underscores the importance of the RENEW study,” said Dr. William Sheridan, chief medical officer of BioCryst. “We believe an oral Factor D inhibitor could be a groundbreaking therapeutic option for nephritis conditions that are driven by the alternative pathway of complement. Coupled with our recent initiations of the REDEEM-1 and REDEEM-2 pivotal trials in PNH, we are excited to advance our BCX9930 clinical program across four separate complement-mediated diseases.”

BioCryst recently announced it has begun enrolling patients in the REDEEM-1 and REDEEM-2 pivotal trials evaluating BCX9930 for patients with PNH. REDEEM-1 is a randomized, open-label, active comparator-controlled study of the efficacy and safety of oral BCX9930 monotherapy in PNH patients with an inadequate response to a C5 inhibitor. REDEEM-2 is a randomized, placebo-controlled study to evaluate the efficacy and safety of oral BCX9930 as monotherapy versus placebo in PNH patients not currently receiving complement inhibitor therapy.

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 RENEW PoC basket trial and advance to pivotal trials in C3G, IgAN and PMN
• Commence PoC trials in other complement-mediated diseases
