About this study

Official title: A Prospective, Open-Label, Dose-Escalation Phase 1 Study of Intra-Articular Administration of an Allogeneic Human Placental Tissue Particulate (PTP-001) for the Treatment of Knee Osteoarthritis

Evaluation of safety, tolerability, and efficacy of a single intra-articular (IA) injection of PTP-001, an allogeneic placental tissue particulate, in individuals with knee osteoarthritis (OA).

Read the detailed description

This open-label, dose-escalation study is expected to enroll 20 participants, 40-80 years of age and test two doses (low and high dose) of PTP-001, an allogeneic placental tissue particulate, in two unique cohorts of 10 participants each. Each participant will receive a single intra-articular (IA) injection of PTP-001. Following the completion of the first cohort in which 10 participants (Kellgren-Lawrence Grade 2 or 3 knee OA) will be treated with the low dose of PTP-001, safety data will be reviewed by an independent Data and Safety Monitoring Board (DSMB).

What is being measured

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

  1. Incidence of local and systemic treatment emergent adverse events (AEs) and incidence of abnormal laboratory and immunogenicity panels

    Incidence of local and systemic treatment emergent adverse events (AEs), including clinical laboratory and immunogenicity panels, after a single intra-articular injection of PTP-001.

    Measured: Baseline to Week 52

Secondary outcomes (6)
  1. Western Ontario and McMaster University (WOMAC) Pain Responder Rate

    Measured: Week 26 and Week 52

  2. WOMAC Physical Function Responder Rate

    Measured: Week 26 and Week 52

  3. Change from baseline in pain of the index knee, by evaluating the WOMAC Pain subscale score (the possible total score ranging from 0-50 for pain)

    WOMAC Numerical Rating Scale (NRS) 3.1 questionnaire is a health status measure questionnaire of 24 questions comprising 3 subscales (pain, stiffness and physical function). WOMAC A (measure of pain) is measured on 11-point NRS ranging from 0 (none) to 10 (extreme), where higher score represents higher pain.

    Measured: Baseline to Week 52

  4. Change from baseline in physical function of the index knee, by evaluating the WOMAC Physical Function subscale score (the possible total score ranging from 0-170 for Physical Function)

    WOMAC Numerical Rating Scale (NRS) 3.1 questionnaire is a health status measure questionnaire of 24 questions comprising 3 subscales (pain, stiffness and physical function). WOMAC C (measure of physical function) is measured on 11-point NRS ranging from 0 (none) to 10 (extreme), where higher score represents higher pain.

    Measured: Baseline to Week 52

  5. Change from baseline in patient global assessment of OA, by assessing the participants assessment of how they are doing considering arthritis in index knee (the possible answers include "Very Good", "Good", "Acceptable", "Poor", "Very Poor"

    Measured: Baseline to Week 52

  6. Change from baseline in health-related quality of life, by assessing the items from the Short Form 36 (SF-36) survey

    The SF-36 measures 8 domains: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health (the possible total normalized score ranges from 0-100). Higher scores on the SF-36 indicate better health status.

    Measured: Baseline to Week 52

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Biological: PTP-001 in people with Knee Osteoarthritis, run by Bioventus LLC at 2 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 7 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: status not confirmed, as of the sponsor's last update on 22 Dec 2021. 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 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

Results are not available in the source record.

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?

Incidence of local and systemic treatment emergent adverse events (AEs) and incidence of abnormal laboratory and immunogenicity panels (time frame: Baseline to Week 52). 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 NCT04632966, which also lists 2 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 22 Dec 2021.
