BioCryst Begins Enrollment in Proof-of-Concept Trial to Confirm Safe, Effective, Once-daily Dose of Oral Factor D Inhibitor, BCX10013
RESEARCH TRIANGLE PARK, N.C., Oct. 26, 2023 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced the enrollment of the first patient in a proof-of-concept clinical trial evaluating BCX10013, a potential once-daily, oral Factor D inhibitor for the treatment of complement-mediated diseases.
The goal of this proof-of-concept trial is to understand the preliminary efficacy and safety profile of once-daily dosing with BCX10013. If the results in patients living with paroxysmal nocturnal hemoglobinuria (PNH) confirm its potential for a best-in-class profile, the company plans to advance into a pivotal program in patients living with renal complement-mediated diseases, including IgA nephropathy (IgAN).
“BioCryst is committed to developing first-in-class or best-in-class medicines, and an oral Factor D inhibitor with once-daily dosing that has an excellent safety profile and strong efficacy would be differentiated and address significant unmet needs of patients living with complement-mediated diseases. By studying BCX10013 in patients living with PNH, we plan to efficiently evaluate alternative pathway activity with well-defined biomarkers, such as LDH and hemoglobin, to determine if we have a safe, effective once-daily dose that meets our criteria to move forward into a pivotal program,” said Dr. Ryan Arnold, chief medical officer of BioCryst.
The trial is an open-label, multicenter dose escalation study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and therapeutic potential of BCX10013 in up to 15 adult patients with PNH and is being conducted in countries that do not have access to standard-of-care complement inhibitor therapy. The trial design employs intra-subject dose escalation approximately every four weeks with the option to continue treatment for up to 24 weeks. The primary endpoints of the trial are incidence of treatment-emergent adverse events and graded laboratory abnormalities, and changes from baseline in laboratory analytes, vital signs, electrocardiograms and physical examination findings. Select secondary endpoints to evaluate efficacy include change from baseline in lactate dehydrogenase (LDH), PNH red blood cell to white blood cell clone size ratio, hemoglobin level and proportion of patients who are transfusion-free, among other biomarkers.
In addition to BCX10013, which is designed to target Factor D in the alternative pathway, BioCryst is pursuing medicines directed at other targets across the classical, lectin and terminal pathways of the complement system. The goal of the company’s overall complement program is to advance several potential best-in-class compounds across multiple pathways in the complement system to treat many complement-mediated diseases.
