Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
At least 30 evaluable patients will be enrolled to receive a single dose of 1.0 mg/kg FDY-5301 or placebo (n=15 per group) by bolus injection intra-operatively by the surgeon or medical team. Patients undergoing unilateral TKA with tourniquet use intra-operatively will receive either FDY-5301 or volume matched placebo after informed consent is obtained, provided the tourniquet has been inflated at least 40 minutes, within 5-10 minutes prior to tourniquet deflation and limb reperfusion. For each participant, the study will consist of screening, total knee arthroplasty (TKA) and study drug treatment on day 1, evaluations on day 2, and follow-up visits at 3 weeks and 6 weeks after receiving the study drug

All patients will have study outcomes monitored for 2 days and at 3 weeks and 6 weeks post operatively.
Subject to the results in this cohort of patients, a decision will be made to proceed with more patients or other doses in future cohorts, or not.
Intervention code [1] 300860 0
Treatment: Drugs
Comparator / control treatment
The placebo product is sterile normal saline containing no drug substance. Each 20 mL (fill volume) vial will be a clear solution and is formulated to contain 9 g/L of NaCl
Control group
Placebo

Outcomes
Primary outcome [1] 305464 0
The functional mobility assessment (standardized stair ascent and descent assessment) will compare the amount of time it takes for placebo vs. FDY-5301 treated patients to ascend and descend a set of stairs at 6 weeks post-TKA and will be expressed as change from baseline in stair ascent and descent times..
Timepoint [1] 305464 0
The functional mobility assessment (muscle strength by isometric extension and flexion and muscle function ) is performed only at screening and 6 weeks after surgery (TKA) due to the required healing time after TKA [primary timepoint]
Secondary outcome [1] 345329 0
Measure of additional functional mobility outcomes including TUG and 6 minutes walking distance
Timepoint [1] 345329 0
These measurements will be evaluated at screening and 6 week post- TKA only due to the healing from the TKA
Secondary outcome [2] 345330 0
This is a composite outcome of quadriceps and hamstring strength tests which is measured using a hand-held dynamometer and compared results between screening and 6 week post TKA.
Timepoint [2] 345330 0
Strength tests will be conducted at screening and 6 weeks post TKA
Secondary outcome [3] 345331 0
MRI evaluation (which is a composite outcome of quadriceps and other thigh muscle volume) - in both legs
Timepoint [3] 345331 0
MRI will be evaluated at screening and 3 and 6 weeks post -TKA
Secondary outcome [4] 346467 0
KOOS knee survey patient questionnaire will be used. The KOOS accesses pain, function, mobility and quality of life at the same time
Timepoint [4] 346467 0
The KOOS will be completed by the participant at screening and 3 and 6 weeks post- TKA
Secondary outcome [5] 347850 0
Explore biomarkers of FDY-5301 activity and muscle injury and inflammation from plasma and serum samples
Timepoint [5] 347850 0
Biomarkers are taken at screening, day 0 (treatment), day 1, 3 weeks and 6 weeks post TKA
Secondary outcome [6] 347964 0
Safety lab values composed outcome of clinical chemistry,. haematology and thyroid values to evaluate safety of treatment with serum assay
Timepoint [6] 347964 0
Safety evaluation is performed at screening, day 1, 3 and 6 weeks follow-up post TKA
Secondary outcome [7] 347965 0
Composite outcome of postoperative pain (evaluated with the KOOS questionnaire), time to first analgesic (hospital record), time to hospital discharge (hospital record), and the time it takes to return to normal function (hospital records) and quality of life (KOOS) will be compared between treatment groups.
Timepoint [7] 347965 0
These will be documented when applicable, either at screening and/or day 0, day 1, 3 and 6 weeks post TKA.

Statistical methods / analysis
The primary outcome for this study will be functional mobility assessed by timed stair ascent and descent compared between the FDY-5301 and placebo treated groups at 6 weeks post-TKA.
A total sample size of 30 patients, ie. 15 per group will provide 80% power to detect a statistically siginificant difference of 31.4% between groups in timed stair ascent and descent at 6 weeks expressed as percent change over baseline ( two-sided alpha=0.05%). Equal variance based on a standard deviation of 15.9% for each group was assumed. These metrics are based on published data.
Statistical evaluation of our data will be performed using separate analysis of covariance (ANOVA) models at 2 weeks and 6 weeks post-TKA, comparing the placebo vs. FDY-5301 treated groups in terms of change from baseline on anatomical, physiological and functional mobility measures. Differences between the means will be considered significant at P = 0.05. All values will be expressed as the mean (SE) or a percentage.
Multilevel models (MLM) will be used to determine correlations between muscle atrophy and other covariates with functional mobility within the context of nested non-independent responses such as change from baseline over time in each patient.
In addition to the measurement of safety and efficacy parameters in this study, soluble biomarker levels will also be assessed.
