New Drug Shows Hope for ADPKD Treatment

November 11, 2012 - Autosomal dominant polycystic kidney disease (ADPKD) is the most commonly inherited disease of the kidneys, yet there are few known effective treatments. Results of a Phase III Clinical Trial presented at the November 2012 American Society of Nephrology (ASN) annual meeting indicate the tide may be turning.

In ADPKD, many cysts form in the kidney, becoming large and fluid-filled. Over time, pressure from these cysts slowly damages kidney tissue. Painful and often causing hypertension, ADPKD leads to end-stage kidney disease (renal failure) in 50% of diagnosed cases.

Early studies indicated that V2-receptor antagonists can prevent cyst growth and slow the deterioration of kidney function. The V2-receptor antagonists are a form of treatment which targets vasopressin, a hormone that enables water absorption by the kidney and plays an important role in proper hydration. When present in high levels, however, vasopressin can cause high blood pressure.

At the most recent ASN meeting, Otsuka Pharmaceuticals Co., Ltd. announced encouraging clinical trial results for tolvaptan, a drug that works through the V2- receptor. Tolvaptan showed a decline in kidney cyst growth, a slowed decline in kidney function, and reduced risk of hypertension. Participants receiving tolvaptan, however, did report discontinuing treatment due to adverse events, such as excessive thirst related to aquaresis (increased urination that does not affect the body’s electrolyte metabolism), and other side effects unrelated to the regular symptoms of ADPKD.

The Kidney Foundation of Canada has funded research related to the V2-receptor by Drs. Bichet and Bouvier. Dr. Daniel Bichet, a recipient of the Foundation’s Medal for Research Excellence, is a nephrologists at Montreal’s Sacré-Cœur Hospital and at the Université de Montréal.  Dr. Michel Bouvier is a Principal Investigator with the Université de Montréal’s Immunology and Cancer Research Institute.
