Altus Pharmaceuticals Reports ALTU-237 Phase 1 Clinical Trial Results
"In this study ALTU-237 was safe and well-tolerated in humans," commented Georges Gemayel, Ph.D., President and Chief Executive Officer at Altus Pharmaceuticals. "Healthy adult volunteers received a high oxalate diet and their urinary oxalate increased to the upper limit of the normal range. The ALTU-237 treatment did not result in a substantial or dose-dependent reduction in urinary oxalate levels. Healthy volunteers do not have the underlying pathophysiology of hyperoxaluria and therefore proof of concept for ALTU-237 can only be evaluated in hyperoxaluria patients."
Dr. Gemayel concluded, "Going forward, we will complete the analysis of the data and evaluate ALTU-237 in conjunction with our other pipeline programs."
The ALTU-237 Phase I clinical trial was a single-center, double-blind, placebo-controlled, dose escalating study. The primary objective was to evaluate the safety and tolerability of ALTU-237 in healthy adult volunteers. The study enrolled 58 healthy adults that were randomized to receive one of four doses of ALTU-237 (900; 3,600; 10,800 or 18,000 units per day) or placebo. All doses were well-tolerated and no severe adverse events were reported. Trial participants consumed a controlled, high oxalate diet and the effect of ATU-237 was measured by comparing the levels of urinary oxalate before and after the administration of ALTU-237 or placebo.
Hyperoxaluria is a disease characterized by excessively high levels of oxalate in the urine, which can be a precursor to forming kidney stones. Hyperoxaluria can be caused by either excessive absorption of dietary oxalate (enteric hyperoxaluria) or increased endogenous production of oxalate (primary hyperoxaluria). When untreated, primary hyperoxaluria could lead to recurrent kidney stones and could contribute to renal failure. Ultimately, patients suffering from severe primary hyperoxaluria experience calcium oxalate deposits in their organs, which, if left untreated, could lead to death.
