About this study

Official title: A Phase 3 Randomized Study to Confirm the Efficacy of an Intra-Articular Injection of Ampion™ in Adults With Pain Due to Severe Osteoarthritis of the Knee

This is a phase 3 randomized study to confirm the efficacy of an intra-articular injection of Ampion™ in adults with pain due to severe osteoarthritis of the knee.

Read the detailed description

A Randomized Study to Confirm the Efficacy of an Intra-Articular Injection of Ampion™ in Adults With Pain Due to Severe Osteoarthritis of the Knee

There will be a 7-day screening period for each subject followed by a 12-week participation period.

The primary trial objective is to evaluate the clinical efficacy of Ampion using the Outcome Measures in Rheumatology Clinical Trials and Osteoarthritis Research Society International (OMERACT-OARSI) (using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) 3.1 Index and Patient's Global Assessment as assessments).

The secondary trial objectives are to evaluate the safety of a single intra-articular injection (4 mL) of Ampion.

Being tested

What is being measured

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

  1. Number of Participants Classified as Responders

    Using the Outcome Measures in Rheumatology Clinical Trials and Osteoarthritis Research Society International (OMERACT-OARSI) criteria of WOMAC A Pain subscore, WOMAC C Function subscore, and PGA as composite endpoints. A patient in this study will be considered a responder for the purpose of efficacy analysis if the following criteria are met:

    (1) demonstration of ≥ 50% improvement AND a 1.0-unit change in pain OR 1.0-unit change in function OR

    If the patient does not meet this criterion, then the patient must demonstrate at least 2 of the following:

    • Improvement in pain (WOMAC A) ≥20% and a 0.5 point absolute change in pain from Baseline on the 5-point Likert scale
    • Improvement in function (WOMAC C) ≥20% and a 0.5 point absolute change in function from Baseline on the 5-point Likert scale
    • Improvement in patient global assessment (PGA) ≥20% and a 0.5 point absolute change in function from Baseline on the 5-point Likert scale

    Measured: Determined from Baseline to 12 Weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 4 mL injection of Ampion in people with Osteoarthritis, Knee and Knee Osteoarthritis, run by Ampio Pharmaceuticals. Inc. at 13 sites 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 10 inclusion and 22 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 9 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites 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 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?

Yes. Results are posted in the registry (first posted 8 Aug 2022). 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?

Number of Participants Classified as Responders (time frame: Determined from Baseline to 12 Weeks). 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 NCT03182686, which also lists 1 linked publication.

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 9 Aug 2022.
