Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1: Pentosan polysulfate sodium for injection, 100 mg/ml.
Arm 2: 0.9% NaCl for injection.

Treatment (active or placebo) will be administered by sub-cutaneous injection, in a randomised, double blinded manner by trained clinical trial staff at clinical trial sites, in a ratio of 2:1 active:placebo.

Drug accountability logs will be maintained and monitored throughout the study.

The dosage regime is 2mg/kg (or equivalent volume of placebo) by subcutaneous injection, twice weekly, for 6 weeks.
