Phase 1

Completed

• Conditions: Osteoarthritis, Knee
• Interventions: Biological: APS

• Registration Number: NCT02262364
• Lead Sponsor: Zimmer Biomet

Brief Summary

The primary objective of this study is to assess the safety of a single injection of APS.

Detailed Description

The primary objective of this study is to assess the safety of a single injection of APS in patients with painful unilateral knee osteoarthritis and who have not been able to get satisfactory pain relief with other treatments through one-month post treatment and monitor subjects for adverse events through 12 months.

Primary Outcome Measures

Name	Time	Method
Adverse Events	1 Year	Adverse Events and Serious Adverse Events

Secondary Outcome Measures

Name	Time	Method
Change From Baseline to 12 Months in Pain, Stiffness, and Function in Daily Living Measured With WOMAC Questionnaire	12 months	The WOMAC LK 3.1 questionnaire is a validated tool commonly used for assessing knee pain, stiffness, and function. The WOMAC LK 3.1 questionnaire has 24 items that the patient addresses about the knee: 5 items on the pain subscale, 2 on the stiffness subscale, and 17 on the physical function subscale. Each item is answered on a 5-point Likert scale, with grading from 0 (none or never) to 4 (extreme or always). A higher score indicates worse pain, stiffness, or functional limitation.; The WOMAC pain subscale consists of five questions scored from 0 to 4. The pain score has a range of 0 (no pain) to 20 (maximal pain).; The WOMAC stiffness subscale consists of two questions scored from 0 to 4. The stiffness score has a range of 0 (no stiffness) to 8 (maximal stiffness).; The WOMAC physical function subscale consists of seventeen questions scored from 0 to 4. The physical function score has a range of 0 (no functional limitation) to 68 (maximal functional limitation).
Change From Baseline to 12 Months in Pain as Measured by the Numeric Rating Scale (NRS)	12 months	The Numeric Rating Scale (NRS) is a validated measure of knee pain. The NRS is an 11 point Likert type scale anchored by 0 "no pain" and 10 "worst possible pain". Subjects rate their average pain over the last 24 hours.
Change From Baseline to 12 Months in Pain as Measured With Knee Injury and Osteoarthritis Outcome Score (KOOS)	12 months	The KOOS questionnaire is a commonly used instrument to assess the patient's opinion about their knee and associated problems. KOOS consists of 5 subscales: Pain (9 questions), Symptoms (7 questions), Function in daily living (ADL) (17 questions), Function in sport and recreation (Sport/Rec) (5 questions) and knee related Quality of Life (QOL) (4 questions). The previous week is used as the time period for answering the questions.; A higher score on the KOOS questionnaire indicates fewer problems, and 0 indicates extreme problems. Each subscale score is calculated independently. The mean score of the individual items of each subscale is calculated and divided by 4 (the highest possible score for a single answer option). Traditionally in orthopedics, 100 indicates no problems and 0 indicates extreme problems. The normalized score is transformed to meet this standard.
