研究概览

简要总结

The purpose of this study is to measure the change in pain and function with subcutaneous injections of pentosan polysulfate sodium (PPS) compared with subcutaneous injections of placebo in participants with knee osteoarthritis pain.

Study details include:

  • The study duration will be up to 31 weeks per participant
  • The treatment duration will be 6 weeks.
  • The visit frequency will be twice weekly during treatment.
  • The visit frequency will be every 4 weeks during the follow-up period.

详细描述

This is a 2-stage, adaptive, randomized, double-blind, placebo-controlled, multicenter study that will evaluate the dose and treatment effect of PPS in participants with knee OA pain.

In Stage 1 (dose selection), approximately 468 participants will be randomised 1:1:1:1 to receive 1 of 3 PPS dose regimens or placebo for 6 weeks. A minimum of 96 participants (24 within each dose group) will be assigned to the Pharmacokinetic (PK) subset.

Participants in Stage 1 will be randomly allocated to receive:

  • 1.5 mg/kg calculated for ideal body weight (IBW) PPS twice weekly
  • 2 mg/kg IBW PPS once weekly + placebo once weekly
  • 100/150/180 mg PPS if ≤ 65 kg/ ≥ 65 kg and ≤ 90kg/ > 90kg IBW+ placebo once weekly
  • placebo twice weekly

In Stage 2, approximately 470 participants will be randomized 1:1 to receive the selected PPS dose regimen or placebo for 6 weeks. Approximately 150 participants (75 per group) will be assigned to the PK subset.

结局指标

主要结局

Change from baseline at Day 56 in knee pain as assessed by the average pain sub-scale score of the WOMAC® NRS 3.1 Index.

时间窗: Baseline, Day 56

WOMAC: The WOMAC® NRS 3.1 Index is a validated, self-administered, health status questionnaire that assesses pain, stiffness, and function in patients with hip or knee OA . The WOMAC pain sub-scale is a 5-item questionnaire used to assess the amount of pain experienced due to OA of index joint (knee) during the past 48 hours. It is calculated as the mean of scores from 5 individual questions scored on a numerical rating scale (NRS). Scores for each question and WOMAC Pain sub-scale score on NRS ranged from 0 (no pain) to 10 (extreme pain), where higher scores indicate higher pain.
