Interleukin-1 Inhibitor

Biologic Therapy for Osteoarthritis Prevention After ACL Injury

Phase < 1
Recruiting
Research Sponsored by University of California, Los Angeles
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
no more than grade 1 medial collateral ligament injury
patients age 18 to 35 years with closed growth plates as visualized on plain radiographs who participate in cutting and pivoting activities.
Must not have
multi-ligamentous knee injury
current malignancy
Timeline
Screening 3 weeks
Treatment Varies
Follow Up surveys will be obtained prior to surgery and then at 3, 6, 9, 12 and 24 months following surgery

Summary

This trial is testing whether or not a common injury, an ACL tear, can be prevented from turning into arthritis by using a naturally occurring protein.

Who is the study for?
This trial is for men and women aged 18-35 with a recent ACL injury who plan to have ACL reconstruction surgery within 45 days. They must not have severe knee injuries besides the ACL, no history of certain diseases or conditions, and no prior treatments that could interfere with the study.
What is being tested?
The trial tests if injecting Anakinra (a biologic therapy) into the knee after an ACL injury can prevent osteoarthritis. Participants are randomly placed in two groups: one gets Anakinra injections, while the other receives placebo saline injections before their surgery.
What are the potential side effects?
Anakinra may cause reactions at the injection site, increased risk of infection due to immune system suppression, headaches, nausea, and potential allergic reactions in those sensitive to its components.
