October 22, 2009 updated by: Osteologix

A Dose-response Study With Strontium Malonate in Postmenopausal Women. A 12 Week, Multi National, Double Blind, Randomized, 5 Arms, Parallel Group Placebo Controlled Open Label Active Controlled, Phase II Study With 3 Dose Levels of Strontium Malonate and Protelos Within Post Menopausal Women With a BMDT-score Below -1

The primary objective of the study is to compare dose-response effect of three dose levels of strontium malonate to placebo on bone resorption quantified by S-CTX-1 following 12 weeks of treatment.

Detailed Description

275 post menopausal women are treated with either 750 mg strontium malonate, 1000 mg strontium malonate, 2000 mg strontium malonate, 2 g Protelos® or placebo.

Patients are treated for 12 weeks. A follow up period of 4 weeks is planned for the main study and a follow up period of 8 weeks is planned for approximately 20% of the patients to follow post treatment CTX-1 activity.

Apart from S-CTS-1 also response on other bio markers are evaluated as well as BMD.
