Study of Safety and Efficacy of 6 mL Synvisc-One (Hylan G-F 20) in Indian Patients With Symptomatic Osteoarthritis of Knee(s) After Initial and Repeat Treatment

Genzyme, a Sanofi Company394 enrolled

Overview

Primary Objective: To evaluate the safety and efficacy of a single 6 mL intraarticular (IA) injection of Synvisc-One in participants in India with symptomatic osteoarthritis (OA) of the knee(s). Secondary Objective: To evaluate the safety and short-term efficacy of a repeat treatment with Synvisc-One.

A period of approximately 19 months was anticipated from the time the first participants was enrolled in the study to the completion of the study (last participant out). Individual participant participation lasted from 7 to 13 months depending on the timing of repeat treatment.

Inclusion Criteria: * Male and female participant aged 30 years or older, with active lifestyle. * The participant must be able to read, understand, and sign an informed consent form, understand requirements for followup visits, and must be willing to provide information at the scheduled evaluations. * The participant had a diagnosis of OA of the target knee confirmed by recent X-ray (mild to moderate joint space narrowing and/or osteophytes (ie, Kellgren Lawrence \[KL\] Grade I-III), predominant in the tibiofemoral compartment. * WOMAC A1 baseline 100 mm visual analog scale (VAS) score from 40-80 mm (moderate or severe walking pain) in the target knee. * Participants with bilateral disease may be included in the study with the below strict conditions: * Only one knee included in the efficacy assessment and considered the target knee (the worst knee by the WOMAC A1 pain scale should be selected). The selected knee must meet the inclusion and exclusion criteria. * The non-target knee may also be treated with Synvisc-One and does not need to meet the KL grade knee specific inclusion criteria described above. The other criteria do apply. * If female, must had a negative urine pregnancy test and continue to use a medically acceptable form of contraception for the duration of the study. Otherwise, females must had been surgically sterile or postmenopausal (as documented in the medical history) for at least 1 year. Exclusion Criteria: * Significant (requiring surgical correction) valgus or varus deformity of the knee, ligamentous laxity, or meniscal instability. * Concomitant inflammatory or any other disease/condition which may affect joints (eg, rheumatoid arthritis, metabolic bone disease, psoriasis, gout, pseudogout, or chondrocalcinosis). * History of sepsis in any joint or any clinical concern for a subacute infectious process in the target joint. * History of surgery in the target knee. * Planned surgery on any lower extremity joint. * Clinically significant venous or lymphatic stasis present in the leg(s). * Clinically apparent tense effusion or inflammation at the target knee. * Skin disease or infection in the area of the injection site. * Any musculoskeletal condition that would impede measurement of efficacy at the target knee. * Pregnant or lactating women. * Hypersensitivities to avian proteins and/or any components of hyaluronan-based injection. * Treatment with any hyaluronic acid (HA) or derivatives in the previous 6 months. * Treatment with IA steroids in the previous 3 months. * Any contraindication to IA injection, eg, anticoagulant therapy or clinical concern for potential coagulopathy (eg, liver disease). * Any significant medical condition (eg, significant psychiatric or neurological disorders or active alcohol/drug abuse), any medical condition that is unstable/poorly controlled or other factors (eg, planned relocation) that the Investigator felt would interfere with study evaluations and study participation. The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.

Outcomes

Primary Outcomes

Change From Baseline in WOMAC A1 Subscore at Week 26

Time frame: Baseline, Week 26 (missing data imputed by Last Observation Carried Forward [LOCF]).

Secondary Outcomes

Change From Baseline in WOMAC A1 Subscore at Week 52

Time frame: Baseline, Week 52 (missing data imputed by LOCF)

Change From Baseline in WOMAC A Score at Week 52

Time frame: Baseline, Week 52 (missing data imputed by LOCF)

Change From Baseline in WOMAC B Score at Week 52

WOMAC is health status measure questionnaire comprising 3 subscales (pain, stiffness and physical function). WOMAC B (measure of stiffness) calculated as a mean of 2 individual components, measured using a visual analogue scale (100 mm line marked by participants with score ranging from 0-100). Total score range is 0 to 100, where higher scores indicate higher stiffness. Stiffness is defined as a sensation of decreased ease in movement of joint.

Time frame: Baseline, Week 52 (missing data imputed by LOCF)

Change From Baseline in WOMAC C Score at Week 52

WOMAC is health status measure questionnaire comprising 3 subscales (pain, stiffness and physical function). WOMAC C (measure of physical function) calculated as a mean of 17 individual components, measured using a visual analogue scale (100 mm line marked by participants with score ranging from 0-100). Total score range is 0 to 100, where higher scores indicate higher worse function. Physical function refers to participant's ability to move around and perform usual activities of daily living.

Time frame: Baseline, Week 52 (missing data imputed by LOCF)

Patient Global Assessment (PTGA) Score at Week 52

PTGA (global self-assessment of target knee osteoarthritis condition) was measured using the 5 point Likert scale (0=very well, 1=well, 2=fair, 3=poor, 4=very poor) by participants to rate the osteoarthritis condition. Number of participants with different categories of PTGA score at Week 52 are reported.

Time frame: Week 52 (missing data imputed by LOCF)

Clinician Observer Global Assessment (COGA) Score at Week 52

COGA (global self-assessment of target knee osteoarthritis condition) was measured using the 5 point Likert scale (0=very well, 1=well, 2=fair, 3=poor, 4=very poor) by the physician to rate participant's osteoarthritis condition. Number of participants with different categories of PTGA score at Week 52 are reported.

Time frame: Week 52 (missing data imputed by LOCF).

12-Item Short Form Health Survey (SF-12)

SF-12 health survey is a self-reported questionnaire to measure participant's profile of functional health and well-being. It includes following 12 questions (Q): Q1 In general, health status; Q2a Limitation of moderate activities; Q2b Limitation of climbing; Q3a Less accomplishment due to physical health; Q3b Limited in the kind of work or other activities due to physical health; Q4a Less accomplishment due to emotional problems; Q4b Did work or other activities less carefully than usual due to emotional problems; Q5 Pain interfere with normal work; Q6a Felt calm and peaceful; Q6b Had lot of energy; Q6c Felt downhearted and low; and Q7 Physical health or emotional problems interfered with social activities.
