Vifor Fresenius Medical Care Renal Pharma (VFMCRP) today announced positive results from a phase-III study in China (PA-CL-CHINA-01), evaluating the efficacy of Velphoro® (PA21) compared to sevelamer carbonate in lowering and maintaining serum phosphorus in adult Chinese patients with chronic kidney disease (CKD) on dialysis after 12 weeks of treatment. The study met its primary endpoint demonstrating non-inferiority versus sevelamer carbonate in the change from baseline in serum phosphorus levels at week 12.
Dr. Klaus Henning Jensen, Chief Medical Officer of Vifor Pharma Group commented, “We are delighted by the positive results from the PA-CL-CHINA-01 study, which confirm previous data generated in the US and Europe, and reinforce the potential of Velphoro® as an important new treatment option for dialysis patients with hyperphosphatemia in China where there is a high prevalence of CKD1. This is another important step in our geographic expansion and will further strengthen the position of Velphoro® as a global leader in the calcium-free phosphate binder market2.”
Importantly, patients who received Velphoro® experienced additional benefits compared to those in the sevelamer control group: Serum phosphorus levels in patients treated with Velphoro® declined faster than in the sevelamer group and the average number of tablets taken daily (3.23) was significantly lower than with sevelamer carbonate (6.31). Safety results were consistent with the known safety profile of Velphoro® with no new safety signal observed in Chinese CKD patients with hyperphosphataemia.
VFMCRP intends to submit the Chinese New Drug Application to the National Medical Products Administration’s CDE at the end of 2021.
About the PA-CL-CHINA-01 study
This phase-III study was designed to demonstrate non-inferiority of the change from baseline at week 12 in serum phosphorus between PA21 (Velphoro®) and sevelamer carbonate, and support market expansion of Velphoro® to China. PA-CL-CHINA-01 was an open-label, active-controlled, parallel group, multicenter study with a total of 286 patients randomized: 142 in the Velphoro® arm and 144 in the sevelamer arm. No major protocol deviation related to COVID-19 were reported and no patients were
