C. Have history of primary hypercholesterolemia and total fasting cholesterol above 5.0mmol/L at screening;
D. Have any symptoms associated with OA of the knee for at least 6 months prior to screening visit and confirmation of OA based on the clinical and radiological criteria of American College of Rheumatology Criteria for OA (Altman et al, 1986) of the knee prior or at screening.

Can healthy volunteers participate?
No
Key exclusion criteria

B. Known hypersensitivity to Pentosan Polysulfate or related compounds (e.g. heparin);
C. Any unstable concurrent clinically significant acute, chronic medical conditions or abnormal laboratory findings that, in the judgment of the Investigator, would jeopardise the safety of the patient, interfere with the objectives of the protocol, or affect the patients compliance with the study requirements, as determined by the investigator;
D. Contraindications for MRI including but not limited to pacemaker, metal sutures, presence of shrapnel, or claustrophobia;
E. Current or a recent history (within last 12 months) of bleeding (a gastric or duodenal ulcer or suspicion of GI tract bleeding) or menorrhagia;

• Aspirin (>325 mg per day)
• Centrally-acting pain medications (e.g., pregabalin, gabapentin, duloxetine)
• Opioids (e.g. tramadol)
• Topical therapies (e.g., NSAIDs ) applied to the index knee
• Muscle relaxants (e.g. tetrazepam, diazepam)
N. Prohibited Concomitant Medications:

Statistical methods / analysis
Descriptive statistics of baseline characteristics will be provided; continuous variables will be summarised in terms of means and standard deviation (SD) where appropriate or median (range), categorical variables will be presented as frequency (percentage).
The baseline and 4-month serum triglyceride (TG) measurements will be summarised as mean and standard deviation. The change in serum TG between the baseline and 4-month assessment will be summarised as mean with corresponding 95% confidence intervals and assessed using a paired t-test.
Secondary outcomes will be summarised in terms of means and standard deviation at each time point and the change in outcome between baseline and follow-up assessments will be summarised in terms of mean (95% CI) and assessed using a paired t-test. To investigate the relationship between the change in lipid levels and change in clinical outcomes across assessments, general estimating equation (GEE) models will be used including time, clinical outcome and adjusting for baseline lipid level.

Summary
Brief summary
This study aims to determine whether oral delivery of PPS drug will lower lipid levels in patients with knee OA. We are also interested to investigate if the improvement in dyslipidaemia might lead to improving OA symptoms and slowing disease progression, as measured by function, pain and MRI, in patients with mild to moderate knee osteoarthritis.
