About this study

Official title: A Multicenter, Randomized, Double-blind, Placebo- and Active-Controlled Phase III Study on the Safety and Efficacy of a Single Intra-articular Administration of JTA-004 in Symptomatic Knee Osteoarthritis

Osteoarthritis is a degenerative, chronic, and progressive joint disease considered as the most common joint disorder worldwide. In healthy joints, there is a continuous process of natural breakdown and repair of cartilage. This process becomes disrupted in OA, leading to degeneration and loss of articular cartilage, along with other joint changes, including subchondral bone remodeling, osteophyte formation, thickening of the capsule and sometimes inflammation of the synovia. JTA-004 is a plasma protein solution supplemented with HA and clonidine developed as a single IA injection for the treatment of knee OA. Local administration of JTA-004 into the joint cavity is intended to relieve chronic pain in subjects suffering from knee OA and discomfort associated with the IA administration.

The JTA-004 Phase III study is a placebo and active-controlled, randomized, double-blind study to evaluate the potential of a single, intra-articular injection of JTA-004 to reduce osteoarthritic pain in the knee at 3 months compared to placebo or active comparator. The study is expected to enrol 742 patients with mild to moderate symptomatic knee osteoarthritis in 22 centres in 6 European countries and Hong Kong SAR.

Being tested
JTA-004, Hylan G-F 20, placebo

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing JTA-004 and Hylan G-F 20 in people with Symptomatic Osteoarthritis of the Knee, run by Bone Therapeutics S.A at 22 sites in 7 countries.

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 9 inclusion and 37 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 2 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 sites in Poland, Belgium, Denmark, Czechia, Moldova and 2 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

knee pain (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 2 Mar 2022.
