WALTHAM, Mass. and STOCKHOLM, Sweden, June 07, 2022 (GLOBE NEWSWIRE) -- Apellis Pharmaceuticals, Inc. (Nasdaq: APLS) and Sobi® (STO:SOBI) today announced that the first patient has been dosed in the Phase 3 VALIANT study investigating pegcetacoplan, a targeted C3 therapy, in primary immune-complex membranoproliferative glomerulonephritis (IC-MPGN) and C3 glomerulopathy (C3G), two rare and debilitating kidney diseases with similar underlying causes and no approved treatment.
“Individuals with IC-MPGN and C3G experience a high burden of disease due to the lack of approved treatments to slow or stop disease progression. These diseases often lead to kidney failure, requiring dialysis or a kidney transplant, imposing further substantial burdens,” said Kristen Hood, MSN, RN, executive director of research engagement at Nephcure Kidney International. “We are excited that Apellis and Sobi are advancing a Phase 3 study of pegcetacoplan in patients aged 12 and older, with primary IC-MPGN or C3G, including those with post-transplant recurrence.”
Uncontrolled activation of the complement cascade, a part of the body’s immune system, is believed to play a critical role in the progression of IC-MPGN and C3G where excessive accumulation of C3 breakdown products in the kidney causes inflammation and organ damage.1-4 It is estimated that 5,000 people in the United States and up to 8,000 in Europe are living with IC-MPGN or C3G,5 and approximately 50% ultimately suffer from kidney failure within five to 10 years of diagnosis.6
“The positive Phase 2 results supported the advancement of pegcetacoplan to a confirmatory Phase 3 study in IC-MPGN and C3G,” said Jeffrey Eisele, Ph.D., chief development officer at Apellis. “There is a significant need for treatments for people living with these rare kidney diseases, and we believe pegcetacoplan, by targeting complement centrally at C3, may have the potential to protect kidney function and preserve patient quality of life.”
“Sobi and Apellis are the only companies actively pursuing a treatment for IC-MPGN,” said Anders Ullman, M.D., Ph.D., head of research and development and chief medical officer at Sobi. “We are pleased that the first patient has been dosed in this Phase 3 study for IC-MPGN and C3G, both of which represent an extremely high unmet medical need. We are committed to bringing a meaningful treatment to patients affected by these severe diseases.”
About the VALIANT Study
The VALIANT Phase 3 study (NCT05067127) is a randomized, placebo-controlled, double-blinded, multi-center study designed to evaluate pegcetacoplan efficacy and safety in approximately 90 patients who are 12 years of age and older with primary IC-MPGN or C3G. It is the only study to include both native kidney patients and patients who have recurrent disease after receiving a kidney transplant. Study participants will be randomized to receive 1080 mg of pegcetacoplan or placebo twice weekly for 26 weeks. Following this 26-week randomized controlled period, patients will proceed to a 26-week open-label phase in which all patients receive pegcetacoplan. The primary endpoint of the study is the proportion of study participants with a reduction from baseline in urine protein-to-creatinine ratio (uPCR) of at least 50% at Week 26. uPCR is an important indicator of kidney function.
About Immune-Complex Membranoproliferative Glomerulonephritis (IC-MPGN) and C3 Glomerulopathy (C3G)
IC-MPGN and C3G are rare, debilitating kidney diseases that are estimated to affect 5,000 people in the United States and up to 8,000 in Europe.5 There are no approved therapies for the diseases, and symptoms include blood in the urine, dark foamy urine due to the presence of protein, swelling, and high blood pressure.7 Approximately 50% of people living with IC-MPGN and C3G ultimately suffer from kidney failure within five to 10 years of diagnosis.6 There are no treatments available that target the underlying complement-mediated mechanism of these diseases and prevent loss of kidney function, before or after renal transplant. Although IC-MPGN is considered a distinct disease from C3G, the underlying cause and progression of the two diseases are remarkably similar and include overactivation of the complement cascade, with excessive accumulation of C3 breakdown products in the kidney causing inflammation and damage to the organ.1-4,8
About Pegcetacoplan in Rare Diseases
Pegcetacoplan is a targeted C3 therapy designed to regulate excessive activation of the complement cascade, a part of the body’s immune system, which can lead to the onset and progression of many serious diseases. Pegcetacoplan is under investigation for several rare diseases across hematology, nephrology, and neurology. Pegcetacoplan is approved for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) in the United States, Australia, and Saudi Arabia as EMPAVELI® and in the European Union and United Kingdom as Aspaveli®.
