Change from pretreatment baseline in pain intensity assessed by participant self report (WOMAC Pain subscale). | 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. | At 2 weeks, 3 months, 4 months, 5 months. |
Change from pretreatment baseline in function assessed by participant self-report (WOMAC Function subscale). | 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. | At 2 weeks, 3 months, 4 months, 5 months, and 6 months. |
Change from pretreatment baseline in the weekly average of daily pain assessed by patient self report (NRS). | 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'. | At 2 weeks, 3 months, 4 months, 5 months, and 6 months. |
Change from pretreatment baseline in patient global assessment of OA (PGA-OA) assessed by participant self report. | 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". | At 2 weeks, 3 months, 4 months, 5 months, and 6 months. |
Change from pretreatment baseline in participant self-reported quality of life measured by SF-36 overall score, PCS, and MCS. | 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. | At 3 months and 6 months. |
Response to PTP-001 on the OMERACT-OARSI responder criteria. | 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). | At 2 weeks, 3 months, and 6 months. |
