About this study

Official title: Early Anti-inflammatory Treatment in Patients With Acute ACL Tear

This research study is the first of its kind and will allow health care professionals and researchers to answer many questions about the reasons why anterior cruciate ligament (ACL) injury leads to knee pain and disability and osteoarthritis. We also hope that this study will be the beginning of new, more powerful and safer drugs to help patients with ACL injuries heal sooner and return to sports or daily activities pain free. Study participants will be recruited from the University of Kentucky and Vanderbilt University.

The purpose of this research is to gather information on how safe and effective Kenalog® is in alleviating knee pain following ACL rupture.

Read the detailed description

Injury to the knee during sports participation often involves partial of full detachment of the ACL. ACL tears cause pain, swelling and inflammation. While the swelling and inflammation usually goes away in time, individuals with ACL injuries may experience pain and notice knee instability (knee slipping, etc.). Often surgery can repair or replace the ACL within the joint, allowing individuals the ability to walk or run again pain free or participate in sports. Unfortunately, osteoarthritis of the knee, which also causes pain and swelling, can occur in that same knee 10-20 years later for reasons which are not well understood.

In this research study, we hope to prevent and reduce the initial post-operative pain. The reduction of pain will allow for earlier movement of the knee joint and preparation for surgery. It may also reduce the risk to develop osteoarthritis in individuals with ACL injuries by treating them within 1-2 days after their injury.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Participant Pain Assessment

    Participants with be given a Visual Analog Scale (VAS) pain assessment questionnaire which scores the participant's perceived pain on a scale of 0-10 were zero is no pain and 10 is the worst pain imaginable. The scale will be administered during the initial orthopedic consult after injury and during the participant's pre-operative assessment, usually 1-7 days after the initial consult.

    Measured: Up to seven days

Secondary outcomes (12)
  1. Efficacy of Kenalog to Alleviate Knee Pain

    The efficacy of Kenalog with be determined using the Knee Injury and Osteoarthritis Outcome Score (KOOS) instrument. Participants will self-report knee pain and function through the KOOS questionnaire during the initial orthopedic consult and during the pre-op assessment prior to surgery, between 1 and 7 days later. The scale scores range from 100 (no symptoms) to zero (extreme symptoms).

    Measured: Up to seven days

Data will be presented as the change in IL-1α concentration from knee aspirate collected during the initial orthopedic consult after injury and during the participant's pre-operative assessment, usually 1-7 days after the initial consult.

    Measured: Up to seven days

What is this clinical trial studying?

A Phase 2 study testing Kenalog in people with Anterior Cruciate Ligament (ACL) Tears, run by Cale Jacobs at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Nov 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Participant Pain Assessment (time frame: Up to seven days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01692756, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Dec 2018.
