GOTHENBURG, Sweden, Sept. 8, 2026 /PRNewswire/ -- Epicyt Pharma AB, a Gothenburg-based clinical-stage biopharmaceutical company developing therapies for impaired intestinal calcium uptake, today announced positive topline results from its Phase 1/2a first-in-human study of BAFA in patients following Roux-en-Y gastric bypass (RYGB) surgery. The study demonstrated a statistically significant reduction in urinary calcium excretion together with improvements in key biomarkers of calcium homeostasis. Based on these encouraging findings, Epicyt is preparing to advance BAFA into Phase 2b development.
"In our short proof-of-concept study aimed at showing an immediate calcium balance-effect of our drug candidate, BAFA produced coherent biological effects on markers of calcium homeostasis," says Dr. Ville Wallenius, MD, PhD, Adjunct Professor of Surgery at the University of Gothenburg and Principal Investigator. "Current post-bypass treatment focuses on supplementation of calcium and vitamin D. BAFA represents a fundamentally different approach, improving the body's ability to maintain calcium balance."
BAFA is a first-in-class oral drug candidate combining a bile acid and a short-chain fatty acid to enhance intestinal calcium uptake. The Phase 1/2a study, completed in March 2026, demonstrated a statistically significant reduction in urinary calcium excretion together with improvements in key biomarkers of calcium homeostasis, consistent with improved intestinal calcium uptake.
RYGB is an effective treatment for severe obesity but often leads to impaired calcium uptake, which can contribute to secondary hyperparathyroidism (over-active parathyroid glands), decreased bone density and increased fracture risk. Despite routine supplementation with calcium and vitamin D, an unmet need for therapies that improve calcium homeostasis after bariatric surgery remains.
Approximately 3.5 million people in EU and US live with impaired calcium homeostasis following gastric surgery to treat obesity, with approximately 250,000 new patients added annually.
