Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Score Comparing Cingal® to Saline (ITT)12 WeeksThe change in knee pain from baseline to 12 weeks as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Score comparing the Cingal® group to the Saline group (ITT population). The WOMAC Pain Score is a validated visual analog scale from 0 mm = no pain to 100 mm = highest pain level. A negative number for the difference from baseline indicates reduction in pain. A greater negative difference from baseline means a better outcome.

Participant flow

Recruitment details

594 potential subjects were screened for the study. 226 subjects were screen failures. 368 subjects were randomized into Cingal 13-01 and all received the study injection.

Pre-assignment details

The most common reason that subjects were excluded before being assigned to a study group (screen failures) was that enrollment target had been reached while subjects were in screening process. Other reasons for screen failure included radiological failures; Kellgren-Lawrence grade not meeting eligibility in the index or contralateral knee.

Patient Global Assessment (PGA) Comparing Cingal® to Monovisc® (ITT)

The change from baseline to 1 week in the Patient Global Assessment (PGA) comparing the Cingal® and Monovisc® arms (ITT population). The PGA is completed by the subject answering the question Considering all the ways the osteoarthritis in your STUDY knee affects you, what is your assessment of how much your STUDY knee is bothering you today? The PGA is scored on a 100mm visual analog scale, where 0 = the patient is not bothered, to 100 mm = the patient is bothered to the highest degree. A negative number for the difference from baseline indicates an improvement in the patient assessment. A greater negative difference means a better outcome.
