- Conditions
- Osteoarthritis, Knee
- Interventions
- Biological: PTP-001Other: Placebo control
- Registration Number
- NCT05100225
- Lead Sponsor
- Bioventus LLC
- Brief Summary
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).
- Detailed Description
This is a multiple arm, multicenter, prospective, randomized, double-blind, placebo-controlled, parallel-arm, phase 2 study of intra-articular administration of an allogeneic human placental tissue particulate (PTP-001) for the treatment of knee osteoarthritis. The study is planned to be conducted outside the United States. A total of approximately 210 participants are planned to be randomized to receive 1 of 2 doses of PTP-001 (100 mg or 200 mg) or saline vehicle control (placebo) injection. The purpose of the trial is to evaluate the efficacy, safety and tolerability of a single low dose and high dose of PTP-001 compared to placebo over a 26-week period.

- Primary Outcome Measures
Name Time Method Efficacy - Change from pretreatment baseline in the WOMAC pain subscale At 6 months To evaluate the change from pretreatment baseline in the WOMAC pain sub-score in the target knee on an 11-box numerical rating scale, with categories from 0 (none) to 10 (extreme), normalized on scales of 0-100.
Safety - Incidence of local and systemic AEs Over 6 months To assess the long-term (6 months) incidence of local and systemic AEs, and consists of physical examination, laboratory values, AEs, AESI, and immunogenicity testing.
- Secondary Outcome Measures
Name Time Method Change from pretreatment baseline in participant self-reported quality of life measured by SF-36 overall score, PCS, and MCS. At 3 months and 6 months. The SF-36 measures 8 domains: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health, and has 2 summary scores (physical and mental). The physical health measure includes 4 scales of physical functioning (10 items), role-physical (4 items), bodily pain (2 items), and general health (5 items). The mental health measure is composed of vitality (4 items), social functioning (2 items), role-emotional (3 items), and mental health (5 items).
The assessment is performed on a scale of 0 (maximum disability)-100 (no disability) with higher scores indicating better health status.Change from pretreatment baseline in the weekly average of daily pain assessed by patient self report (NRS). At 2 weeks, 3 months, 4 months, 5 months, and 6 months. The question is an average daily (24-h) pain intensity score on a 0 to 10 NRS scale with 0 indicating 'no pain' and 10 indicating 'pain as bad as you can imagine'.
Response to PTP-001 on the OMERACT-OARSI responder criteria. At 2 weeks, 3 months, and 6 months. The OMERACT-OARSI responder criteria involve changes that are deemed to be clinically relevant in the three domains: pain, function, and Patient Global Assessment. For each of these domains, ranges are defined for absolute and percent changes from baseline that correspond to "high improvement" and "moderate improvement". OMERACT-OARSI response is defined as either i) improvement in pain or physical function ≥50% and an absolute change ≥20 mm on a 100-mm visual analog scale; or (2) improvement of ≥20% and with an absolute change ≥10 mm in at least two of the following three categories: pain, physical function, and patient's global assessment (PGA).
Change from pretreatment baseline in pain intensity assessed by participant self report (WOMAC Pain subscale). At 2 weeks, 3 months, 4 months, 5 months. 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 an 11-box numerical rating scale, with categories from 0 (none) to 10 (extreme), normalized to a scale of 0-100, where higher score represents higher pain.
Change from pretreatment baseline in function assessed by participant self-report (WOMAC Function subscale). At 2 weeks, 3 months, 4 months, 5 months, and 6 months. 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 difficulties in physical function.
Change from pretreatment baseline in patient global assessment of OA (PGA-OA) assessed by participant self report. At 2 weeks, 3 months, 4 months, 5 months, and 6 months. Considering all the ways knee osteoarthritis affects the participants, the question is an average daily (24-h) self-reported global assessment on an 11-box numerical rating scale, with 0 indicating "very good" and 10 indicating "very poor".
