Regulus Initiates Multiple Ascending Dose Study in Healthy Volunteers of RGLS4326 for the Treatment of ADPKD
Published: May 01, 2018
Initial safety and pharmacokinetic results from single ascending dose study support advancement
LA JOLLA, Calif., May 1, 2018 /PRNewswire/ -- Regulus Therapeutics, Inc. (Nasdaq: RGLS), a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, today announced that it has initiated a Phase I multiple ascending dose (MAD) study in healthy volunteers for RGLS4326 for the treatment of autosomal dominant polycystic kidney disease, or ADPKD. RGLS4326 is a novel, first-in-class, oligonucleotide designed to inhibit miR-17 using a unique chemistry that preferentially delivers to the kidney.
"We are pleased to advance the RGLS4326 program with the initiation of the MAD study, which will allow us to further characterize the safety and pharmacokinetic profile of RGLS4326 and establish the dose range that we will study in patients with ADPKD," said Timothy Wright, M.D., Chief R&D Officer of Regulus. "RGLS4326 represents a novel approach to treating ADPKD, a genetic disease leading to progressive loss of kidney function and kidney failure in the majority of patients."
This study is designed to characterize the safety, tolerability, pharmacokinetics and pharmacodynamics of increasing doses of RGLS4326. The MAD study was initiated based on data from the single ascending dose (SAD) Phase I study, which has completed dose escalation and continues in the planned follow-up phase. Preclinical studies with RGLS4326 have demonstrated a reduction in kidney cyst formation, improved kidney weight/body weight ratio, and decreased cyst cell proliferation in mouse models of ADPKD; and decreased cyst formation in cultured human ADPKD cyst cells in vitro.
About Autosomal Dominant Polycystic Kidney Disease (ADPKD)
ADPKD, caused by the mutations in the PKD1 or PKD2 genes, is among the most common human monogenetic disorders and a leading genetic cause of end-stage renal disease. The clinical hallmark of this disease is the development of multiple fluid filled cysts primarily in the kidneys and to a lesser extent in the liver and other organs. Excessive kidney tubule derived cyst cell proliferation, a central pathological feature, fuels the expansion of cysts, ultimately causing end-stage renal disease in approximately 50% of ADPKD patients by age 60. Approximately 1 in 1,000 people bear a mutation in either PKD1 or PKD2 genes worldwide.
