About this study

Official title: A Two Part Protocol Using Double Blind Placebo Control to Assess the Safety, Tolerability, and Pharmacokinetics of Single Escalating Intra-articular Doses Followed by Assessment of Efficacy, Safety, Tolerability and Pharmacokinetics of a Single Intra-articular Dose of the TrkA Inhibitor, GZ389988, in Patients With Painful Osteoarthritis of the Knee

Primary Objective:

To assess the efficacy of a single intraarticular dose of GZ389988 compared to placebo for relief of knee pain in patients with osteoarthritis (OA) of the knee.

Secondary Objectives:

To assess the safety and tolerability of a single intraarticular dose of GZ389988 in patients with painful OA of the knee.

To assess the pharmacokinetic parameters of a single intraarticular dose of GZ389988 in patients with painful OA of the knee.

Read the detailed description

Screening will be performed within 21 days of dosing. Following the single dose of study medication, the study period for each patient will be 84 ± 7 days up to the end-of-study visit.

Total duration for one patient will be up to 16 weeks (up to the end-of-study visit), not including the long-term observational safety follow-up phone call for 12 additional weeks.

The collection of primary endpoint data up to Week 4 for futility analysis is optional. Assuming a possible step-down in dose due to safety/tolerability reasons, the total expected maximum number of included patients could be increased up to a maximum of 182 patients.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing GZ389988, acetaminophen or paracetamol and fixed combination of paracetamol + codeine in people with Osteoarthritis, run by Genzyme, a Sanofi Company at 2 sites in Germany.

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 25 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 13 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Germany. 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?

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?

Change from baseline in weekly mean score of Western Ontario and McMaster Universities Arthritis Index (WOMAC) A1 pain subscore (walking pain) collected daily in the target knee, as measured by the Visual Analogue Scale (VAS) 0-100 (time frame: Averaged over 4 weeks (up to Day 28)). 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 NCT02845271, 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 13 Apr 2022.
