In the fourth cohort, 26 subjects received a fixed dose of 300 mg of farabursen every other week for three months. Consistent with the previously announced interim analysis of efficacy data from the first 14 subjects of this fixed-dose cohort, the full cohort of 26 patients demonstrated similar mechanistic response based on urinary PC1 and PC2 levels as well as a mean halting of htTKV growth over the four-month study period.
Cohort 4 data highlights:
Increases in urinary PC1 and PC2 levels were similar to cohort 3 and reached a similar level of statistical significance compared to placebo (PC1 p=0.026; PC2 p=0.014).
Mean htTKV growth rate over 4 months was 0.05% (SE -0.86% to +0.92%) while placebo subjects in the trial experienced a mean growth rate of 2.58% (SE +1.09% to +4.10%).
Changes in htTKV were highly correlated with changes in renal cyst volume, suggesting farabursen directly impacts disease progression by limiting abnormal cyst growth.
In an exploratory analysis, the combination of patients treated with 3 mg/kg or 300 mg fixed dose farabursen (n=35) were compared to a combined historical control group of placebo-treated patients from prior pivotal ADPKD trials (n=550). Farabursen-treated patients experienced mean reduction in htTKV growth rate (-0.14%) compared to a mean increase of (+1.87%) in placebo-treated patients (p=0.0056).
Farabursen at 300 mg demonstrated a favorable safety and tolerability profile in this study, consistent with earlier cohorts.
