Study Arms (2)

Pentosan Polysulfate Sodium

EXPERIMENTAL

U101 is available as a capsule containing 100 milligrams (mg) of pentosan polysulfate sodium. Subjects will be administered U101 at a dose of 300 milligrams (mg) three times daily (tid) for the initial 8 weeks and then 200 milligrams (mg) twice daily (bid) for another 8 weeks during the study.

Drug: Pentosan Polysulfate Sodium 100 MG Oral Capsule

Placebo Control

PLACEBO COMPARATOR

Placebo to match U101 is available as a capsule in 100 milligrams (mg). Subjects will be administered placebo at a dose of 300 milligrams (mg) three times daily (tid) for the initial 8 weeks and then 200 milligrams (mg) twice daily (bid) for another 8 weeks during the study.

Drug: Placebo
