Introduction to the Phase 2 Clinical Trial
Akebia Therapeutics®, Inc. (Nasdaq: AKBA), a biopharmaceutical company dedicated to enhancing the lives of individuals affected by kidney disease, has recently announced the successful dosing of the first patient in its Phase 2 clinical trial of praliciguat. This oral, once-daily soluble guanylate cyclase (sGC) stimulator is being evaluated for its efficacy in treating focal segmental glomerulosclerosis (FSGS), a rare kidney disease confirmed via biopsy.
Significance of the Phase 2 Trial
The initiation of this Phase 2 trial is a significant milestone for Akebia, as FSGS affects approximately 40,000 patients in the United States and currently has no approved treatments. Dr. Steven K. Burke, Chief Medical Officer at Akebia, expressed enthusiasm regarding the trial, stating, “We are pleased by the timely initiation of this important Phase 2 clinical trial of praliciguat and have successfully dosed the first patient following the defined screening process.”
Trial Design and Objectives
The Phase 2 study is a randomized, double-blind, placebo-controlled, multicenter trial designed to evaluate the safety and efficacy of praliciguat in adults diagnosed with biopsy-confirmed FSGS. Key details of the trial include:
- Approximately 60 patients will be recruited, all receiving maximally tolerated doses of either an angiotensin-converting enzyme inhibitor (ACEi) or an angiotensin receptor blocker (ARB).
- Participants will be randomized in a 1:1 ratio to receive either praliciguat or a placebo for an initial 24-week treatment period.
- After the double-blind phase, all patients will transition to receiving praliciguat in an open-label segment for an additional 24 weeks.
The primary endpoint of this trial is the change from baseline in the urine protein-to-creatinine ratio (UPCR) measured at Week 24, while the secondary endpoint evaluates the percentage of patients achieving partial remission at the same time point.
About Praliciguat
Akebia licensed praliciguat from Cyclerion Therapeutics, Inc. The compound has shown a favorable safety profile, with no significant safety issues observed in earlier Phase 1 studies involving healthy volunteers and Phase 2 studies in patients with heart failure and diabetic kidney disease. Any adverse events related to praliciguat have been infrequent and in line with its known blood pressure lowering effects.
