Arterial stiffness and arterial calcification
MedDRA version: 14.0
Level: LLT
Classification code 10059123
Term: Arterial calcification
System Organ Class: 10047065 - Vascular disorders
|
Intervention(s)
|
Trade Name: Aclasta® 5 mg solution for infusion Pharmaceutical Form: Solution for injection INN or Proposed INN: zoledronic acid monohydrate CAS Number: 165800-06-6 Concentration unit: mg milligram(s) Concentration type: equal Concentration number: 5- Pharmaceutical form of the placebo: Solution for infusion Route of administration of the placebo: Intravenous drip use (Noncurrent)
|
Primary Outcome(s)
|
Main Objective: Does Zoledronic Acid 5 mg once yearly compared to placebo reduces arterial stiffness?
|
Primary end point(s): Reduction in arterial stiffness over time.
|
Secondary Objective: Does the administration of Zoledronic Acid within the same cohort reduce the progression, or reversal of arterial calcification? If no presence of arterial calcification is initially detected, does the use of Zoledronic Acid prevent the condition from occuring? Does Zoledronic acid reduce the change in carotid intima-media thickness from baseline to final visit in the active treatment group compared to placebo group?
|
Timepoint(s) of evaluation of this end point: 3 years
|
Secondary Outcome(s)
|
Timepoint(s) of evaluation of this end point: 3 years
|
Secondary end point(s): Secondary outcomes will be arterial calcification (as measured by aortic CT), common carotid intima-media thickness (CIMT) and high sensitivity CRP (hsCRP).
