Brief summary

Primary Objective: -To evaluate the efficacy of a single 6-milliliter (mL) intra-articular (IA) injection of Hylan G-F 20 measured by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Numerical Rating Scale (NRS) 3.1 A1 score, in comparison to an IA placebo injection over 26 weeks, in Chinese participants with symptomatic Osteoarthritis (OA) of the knee. Secondary Objectives: * To evaluate the efficacy of a single 6-mL IA injection of Hylan G-F 20 measured by 7-day average score of WOMAC A1 pain sub-score in comparison to an IA placebo injection over 26 weeks. * To evaluate the efficacy of a single 6-mL IA injection of Hylan G-F 20 measured by WOMAC A, patient global assessment (PTGA) and clinical observer global assessment (COGA) in comparison to an IA placebo injection over 26 weeks. * To evaluate the response rate of a single 6-mL IA injection of Hylan G-F 20 in comparison to an IA placebo injection over 26 weeks. Response was defined as WOMAC A1 greater than or equal to (\>=) 2-point improvement from baseline on NRS. * To evaluate the safety of a single 6-mL IA injection of Hylan G-F 20, in comparison to an IA placebo injection over 26 weeks.

Detailed description

The duration of the study was 29 weeks at maximum. The screening and wash-out period lasted for up to 14 days, depending on the half-life of the medications followed by an 8-day baseline period including the treatment day. Overall, there were up to 21 days between signing informed consent (at screening visit) and the randomization (Day 1). Treatment was administered on Day 1, and follow-up period was 26 weeks.

WOMAC A (5 items: measure of pain while walking, using stairs, at night while in bed, sitting or lying, and standing); each item was measured on 11-point (NRS) ranging from 0 (none) to 10 (extreme), where lower score represented no pain and higher score represented extreme pain. Total WOMAC A score was the sum of 5 item scores and ranges from 0 (none) to 50 (extreme); where lower score represented no pain and higher score represented extreme pain.
Change From Baseline in Patient Global Self-Assessment (PTGA) Score of Osteoarthritis Over 26 WeeksFrom Baseline up to Week 26PTGA (self-assessment of target knee OA condition) was measured using an 11-point NRS ranging from 0 (best possible) to 10 (worst possible), where lower score represented best possible condition and higher score represented worst possible condition.

For 7-day average WOMAC A1, the baseline value was defined as the average of the WOMAC A1 scores recorded 7 days prior to the first investigational medicinal product (IMP) administration (WOMAC A1 score recorded on Day 1 included). The 7-day average WOMAC A1 was set as missing if 3 or more of the 7 WOMAC A1 scores were missing.

Number of Participants With Treatment Emergent Adverse Events (TEAEs)From Baseline up to Week 26Adverse Event (AE) was defined as any untoward medical occurrence in a participant who received study drug and did not necessarily had a causal relationship with the treatment.

Recruitment details

The study was conducted at 21 sites in China from 21 August 2017 to 28 January 2019. A total of 524 participants were screened, of which, 84 participants were screen failures. Screen failures were mainly due to inclusion criteria not met.

Pre-assignment details

A total of 440 participants were enrolled and randomized in the study. Assignment to arms was done centrally using an interactive voice response system/interactive web response system (IVRS/IWRS) in 1:1 ratio (Placebo: Hylan G-F 20).
