Description of intervention(s) / exposure
This observational trial runs in parallel to the interventional trial MSC-OAK-001 (ACTRN12617001095358). It is designed to assess the efficacy and longer-term safety of investigational product MAG200. Mag200 is a preparation of allogeneic human adipose-derived mesenchymal stem cells (MSCs) in sterile, clinical grade injectable isotonic solution. Up to 40 subjects with a documented diagnosis of osteoarthritis of the knee, confirmed by X-ray and MRI during Screening, and who have met the eligibility criteria for the parallel interventional trial MSC-OAK-001 will be offered the opportunity to enrol in this observational study. Following provision of written informed consent and confirmation of eligibility, eligible subjects will commence both protocols on the same day. Subjects enrolled in Protocol MSC-OAK-001 will be on-study for Months 0-3. Subjects enrolled in Protocol MSC-OAK-002 will be on-study for Months 0-12. Participants will complete questionnaire based follow-up at 0, 1, 3, 6, 9 and 12 months. Participants will undergo radiological follow-up including Xray and MRI at 12 months. Questionnaires will be completed using online software and independently by the participants. Questionnaires are expected to take up to 20minutes. Radiological imaging at 12 months is expected to take up to 1hour.

Participants in this trial will be the same participants enrolled in the interventional trial ACTRN12617001095358.

Statistical methods / analysis
All patients will be included in the ITT population. All analyses use the ITT population.
Analysis of primary endpoint -
The primary endpoint of overall responder will be analysed using a stratified (by timepoint) Cochrane Mantel Haenzel approach for each dose where a 2x2 table (responder x treatment) will be obtained for each timepoint from which the number (and percentage) of responders in each treatment group at each timepoint will be obtained. In addition estimates of the ‘risk difference’ (the difference in percentage of responders calculated as percentage on active – percentage on placebo) and a relative risk (percentage responders on active/percentage responders on placebo) will be obtained. An exact chi-square test will be performed at each timepoint to test whether the percentage of responders was different between active and placebo. In addition the overall, common relative risk (with 95% confidence limits) will be obtained.
Secondary efficacy endpoints and analyses -
To assess the effect of active treatment compared with placebo a mixed model will be fitted with change in NRS/KOOSx as the outcome variable and dose and timepoint (and the dosextimepoint interaction) as factors.
The results for the satisfaction scales and PGIC will be summarised by timepoint and dose.

For cartilage volumes assessment by MRI a general linear model will be used with percentage change as the outcome variable and dose as a factor. Baseline volume will included as a covariate. From the model the adjusted percentage change for each dose will be obtained (with 95% confidence limits) as well as the treatment effect (with 95% confidence limits), defined as percentage change on MAG200 – percentage change on placebo. A p-value will be also obtained to test the null hypothesis no difference between active treatment and placebo against the 2-sided alternative.

Summary
Brief summary
Protocol MSC-OAK-002 is a prospective, observational study that runs concurrently with Protocol MSC-OAK-001 (ANZCTR No. ACTRN12617001095358)

Up to 40 subjects with a documented diagnosis of osteoarthritis of the knee, confirmed by X-ray and MRI during Screening, and who have met the eligibility criteria for Protocol MSC-OAK-001 will be offered the opportunity to enrol in this observational study. Following provision of written informed consent and confirmation of eligibility, eligible subjects will commence both protocols on the same day. Subjects enrolled in Protocol MSC-OAK-001 will be on-study for Months 0-3. Subjects enrolled in Protocol MSC-OAK-002 will be on-study for Months 0-12.

All potential subjects will be required to provide written informed consent prior enrolment.

The study is expected to confirm the safety of donor stem cell treatment in osteoarthritis and also the confirm the most effective treatment dose for pain, functional and structural benefit.
