Outcomes

Primary outcome [1]

OA symptom severity assessed using the WOMAC Index. The WOMAC Index questionnaire was patient self-administered at baseline, and at Weeks 24 and 28. The value for Week 26 was derived by averaging values from Weeks 24 and 28.

Timepoint [1]

26 weeks post SYNVISC-ONE procedure

Secondary outcome [1]

OA symptom severity assessed using the WOMAC Index. The WOMAC Index questionnaire was patient self-administered.

Statistical methods / analysis

The sample size of 130 enrolled patients, was based on the number of patients enrolled in the SYNVISC group (n=127), in a previously reported pharmaco-economics study [Raynauld JP et al. Osteoarthritis Cartilage. 2002;10(7):506-517; Torrance GW et al. Osteoarthritis Cartilage. 2002:10(7):518-527], which was sufficient to detect statistically significant clinically important improvements in the WOMAC Index, PGA, SF36 and HUI-3

Summary

Brief summary

Aims: The goals of the LOBRAS study, were: 1) To evaluate the group-level response to Synvisc-One in knee OA, using patient-centred measures of beneficial and adverse outcome; and 2) To evaluate response and state-attainment criteria and age-specific and gender-specific benchmarks, at the individual patient level, to assess the therapeutic response to Synvisc-One in knee OA.
Methods: The LOBRAS study involved a one year long multi-centre, pragmatic, “real-world” evaluation of the response to Synvisc-One, in 131 patients with knee OA. LOBRAS employed an open, quasi-experimental, one group, repeated measures design, and involved consented patients in Australia, fulfilling inclusion/exclusion criteria, and under the care of a medical specialist (Orthopaedic Surgeon, Rheumatologist, Sports and Exercise Medicine Physician), in routine clinical practice. Prior to, and for 52 weeks following, intra-articular Synvisc-One, patients were repeatedly evaluated, using the WOMAC NRS4.1 Index and the SF-36 questionnaire. The WOMAC NRS4.1 was administered by mobile phone (with paper back-up) at baseline, then once weekly for 12 weeks, and once every four weeks thereafter. The SF-36 was administered on paper, at baseline, then every four weeks thereafter. Patients were also monitored for adverse events.
Data Analyses:
The following analyses were pre-planned:
Effectiveness analyses:
Primary: Repeated measures analysis based on 26 week outcome for WOMAC pain, stiffness, function and total index scores, using continuous data.
Secondary: Repeated measures analysis based on 52 week outcome for WOMAC pain, stiffness, function and total index scores, using continuous data.

Responder analyses based on WOMAC pain, stiffness, function and total index scores, using categorical data.
a)	OMERACT-OARSI Responder Criteria
b)	Minimum Perceptible Clinical Improvement (MPCI)
c)	Minimum Clinically Important Improvement (MCII 75)
d)	WOMAC 20-50-70 Responder Criteria

State-attainment analyses based on WOMAC pain, stiffness, function and total index scores, using categorical data.
a)	Bellamy Low Intensity Symptom State-attainment (BLISS) Index
b)	WOMAC Age- and Gender-specific normative values 
c)	Patient Acceptable Symptom Severity (PASS 75)

Utility analysis using the WOMAC-HUI model for deriving HUI-3 utility values from WOMAC scores
Comparison of 26 week vs. 52 week outcomes for above analyses
Change in SF-36v2 (BL to week 26 and week 52)
Analysis of predictors of outcome at 26 weeks and 52 weeks including age, gender, BMI, KL Grade, Injection site, duration of OA, adverse events.
Time to re-injection in repeat treatment subgroup
Safety/Tolerability Analyses: Descriptive analysis of adverse events
