Study summary

Osteoarthritis (OA) is the most common joint disease affecting millions of people around the world, for which there is unfortunately no cure. Among existing therapies, viscosupplementation, i.e., the injection of hyaluronic acid into the joint, has an established place in the symptomatic treatment of knee OA.

The present Phase IIb/III aiming to assess the safety and efficacy of JTA-004 is organized in two phases. With results obtained in the first phase the best dose of JTA-004 is determined, and the efficacy of the selected dose will then be confirmed in the second phase.

Other exclusion criteria:

  • (BMI) of 35 kg/m2 or greater
Terms in these criteria, in plain language(9)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

What researchers measure

Primary outcomes

  1. Change From Baseline in WOMAC VA3.1 Pain Subscale Score at Month 6

    The primary endpoint is the Western Ontario McMaster universities (WOMAC®) VA3.1 Pain Subscale (subscale A): the individual changes in WOMAC® VA3.1 Pain Subscale Score between Baseline and Month 6 were calculated and compared by analysis of covariance (ANCOVA), adjusted for baseline value, to the Reference group. Results are expressed as "adjusted mean" based on the model used for group comparison. WOMAC Osteoarthritis Index is a tri-dimensional, self-administered, patient-centred health status questionnaire for knee disease severity ans osteonecrosis symptoms. The WOMAC® Index Pain Subscale (VAS format) was used. The VAS score was determined by measuring in millimetres from the left-hand end of the line to the point that the patient marks (0-100 mm) for 5 questions. Results are summed and normalized on a 100 mm scale: 0 represents no knee pain and 100 extreme knee pain.

Results are expressed as "adjusted mean" based on the model used for group comparison. WOMAC Osteoarthritis Index is a tri-dimensional, self-administered, patient-centred health status questionnaire for knee disease severity and osteonecrosis symptoms.
