- Pegcetacoplan demonstrated statistical superiority on the co-primary endpoints of haemoglobin stabilisation (p<0.0001) and reduction in lactate dehydrogenase (LDH) (p<0.0001) compared to standard of care, which did not include complement inhibitors, at week 26 - Mean haemoglobin levels in the pegcetacoplan group increased from 9.4 g/dL to 12.1 g/dL compared to an increase from 8.7 g/dL to 9.4 g/dL on standard of care (p=0.0019)
| STOCKHOLM, May 25, 2021 /PRNewswire/ -- Swedish Orphan Biovitrum AB (publ) (Sobi™) and Apellis Pharmaceuticals Inc (Nasdaq: APLS) (GLOBE NEWSWIRE) today reported positive top-line results from the phase 3 PRINCE study evaluating the efficacy and safety of pegcetacoplan in adults with paroxysmal nocturnal haemoglobinuria (PNH) who are treatment naïve, meaning they had not received a complement inhibitor within three months before entering the study. Pegcetacoplan demonstrated statistical superiority on the co-primary endpoints of haemoglobin stabilization and reduction in lactate dehydrogenase (LDH) compared to standard of care, which did not include complement inhibitors, at week 26.
“The positive PRINCE data showed that pegcetacoplan provided clinically meaningful improvements across multiple measures that are important for patients and build on our recent FDA approval of pegcetacoplan in PNH,” said Federico Grossi, M.D., Ph.D., chief medical officer, Apellis. “Combined with previous studies, these results emphasize the potential of pegcetacoplan to provide disease control for all adults with PNH regardless of prior treatment.” Pegcetacoplan also achieved statistical superiority on several secondary endpoints, including improvements in haemoglobin levels and transfusion avoidance, compared to standard of care, which did not include complement inhibitors.
The safety profile of pegcetacoplan was consistent with previous studies. At week 26, 9 per cent of patients in the pegcetacoplan group experienced a serious adverse event (SAE) compared to 17 per cent on standard of care. One death was reported in each group, and neither were related to treatment. No cases of meningitis or thrombosis were reported in either group. The most common adverse events reported during the study in the pegcetacoplan and standard of care groups, respectively, were injection site reaction (30 per cent vs. 0 per cent), hypokalemia (13 per cent vs. 11 per cent), and fever (9 per cent vs. 0 per cent). “The PRINCE study results reinforce the efficacy and safety profile of pegcetacoplan in PNH,” said Ravi Rao, Head of Research & Development and Chief Medical Officer at Sobi. “Our hope is to contribute to an improvement of care, and to make a difference in the lives of people with this rare blood disease.” Detailed results from the PRINCE study will be presented at medical congresses. About the PRINCE study
The PRINCE study (NCT04085601) is a 2:1 (pegcetacoplan: standard of care) randomized, multi-center, open-label, controlled phase 3 study in 53 treatment-naïve adults with paroxysmal nocturnal haemoglobinuria (PNH). The primary objective of this study was to establish the efficacy and safety of pegcetacoplan in patients who have not received treatment with any complement inhibitor within three months prior to screening. During the 26-week randomized, controlled period, patients received either 1080 mg of pegcetacoplan twice weekly or standard of care therapy, which did not include complement inhibitors. Patients in the standard of care group had the option to escape to the pegcetacoplan group if their haemoglobin decreased 2 g/dL or more from their baseline value.
About pegcetacoplan
Pegcetacoplan is an investigational therapy targeting C3, the central protein in the complement cascade. It acts proximally in the complement cascade controlling both C3bmediated extravascular haemolysis and terminal complementmediated intravascular haemolysis. Pegcetacoplan is being evaluated in several clinical studies across haematology, ophthalmology, nephrology, and neurology. In May 2021, pegcetacoplan was approved as EMPAVELITM in the US for the treatment of adults with paroxysmal nocturnal haemoglobinuria (PNH). The marketing authorisation application for pegcetacoplan for paroxysmal nocturnal haemoglobinuria (PNH) is under review by the European Medicines Agency (EMA). Pegcetacoplan was also granted Fast Track designation by the FDA for the treatment of geographic atrophy and received orphan drug designation for the treatment of C3 glomerulopathy by the FDA and EMA.

About Paroxysmal Nocturnal Haemoglobinuria (PNH)
PNH is a rare, chronic, life-threatening blood disorder characterized by the destruction of oxygen-carrying red blood cells through extravascular and intravascular haemolysis. Persistently low haemoglobin can result in frequent transfusions and debilitating symptoms such as severe fatigue, haemoglobinuria and difficulty breathing (dyspnea).
