Zoledronic Acid for Anterior Cruciate Ligament Injury (ZAPOA Trial)

Phase 1
Recruiting
Led By Gregory Kline, MD
Research Sponsored by University of Calgary
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Participants with combined ligament deficiencies (posterior cruciate, medial and/or lateral collateral) or meniscal injury
Participants must be able to fully extend the knee while supported at the time of the baseline measurement in order to conduct the HR-pQCT scan
Must not have
Patients with severe renal impairment with creatinine clearance <35 mL/min or evidence of acute renal impairment
Prior knee ligament and/or meniscus tears, and/or intra-articular fractures
Timeline
Screening 3 weeks
Treatment Varies
Follow Up 18 months

Summary

This trial will test if zoledronic acid, given as an injection, can help prevent joint degeneration after an ACL injury.

Who is the study for?
This trial is for adults with a recent, complete tear in their anterior cruciate ligament (ACL) who have normal calcium and kidney function. They can have other knee injuries too but shouldn't be pregnant or planning pregnancy soon, have past knee injuries, or conditions affecting bone turnover.
What is being tested?
The study tests if an injection of zoledronic acid can prevent joint damage after an ACL injury compared to a placebo. Participants will receive either the real drug or a placebo without knowing which one they get.
What are the potential side effects?
Zoledronic acid may cause flu-like symptoms, pain at the injection site, nausea, dizziness, and rarely jawbone problems or unusual thigh bone fractures.
