Background information:

About the CALMAG study
The CALMAG study is a 24-week randomised, controlled, multicentre, head-to-head clinical study comparing the efficacy of two phosphate binders, OsvaRen® (calcium acetate/magnesium carbonate from Fresenius Medical Care) and sevelamer hydrochloride (Renagel® from Genzyme Corporation) in patients with chronic kidney disease on dialysis. The CALMAG study was conducted in five European countries.

About OsvaRen®
OsvaRen®, consisting of 435 mg calcium acetate (110 mg calcium) and 235 mg magnesium carbonate (60 mg magnesium), allows effective and safe control of serum phosphorus levels in patients on dialysis. Elevated serum phosphorus levels are an independent predictor of mortality in patients with chronic renal failure and require effective treatment for better achievement of K/DOQI2 and KDIGO3 target ranges. OsvaRen® is now approved in 28 European countries for the treatment of hyperphosphataemia associated with chronic renal insufficiency in patients undergoing dialysis. OsvaRen® is not yet available in all countries and prescribing information may differ between countries. Please consult your local prescribing information.

Important safety information
OsvaRen® is contraindicated in patients with hypophosphataemia, hypercalcaemia, elevated serum magnesium levels of more than 2 mmol/L and/or symptoms of hypermagnesaemia, AV-block III or Myasthenia gravis. Common adverse events reported with OsvaRen® include soft stools, gastrointestinal irritation like nausea, anorexia, sensation of fullness, belching and constipation, diarrhoea. Drug-drug interactions may occur with some medications and should be taken into consideration when instructing patients on how to take OsvaRen®. Patients should be informed to take OsvaRen® with meals and to adhere to their prescribed diets.
