Knee pain study pulled before it even started
NCT ID NCT01122485
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study was designed to test whether PG201, a botanical drug, could reduce pain and improve function in people with knee osteoarthritis. It planned to enroll Korean adults aged 40 to 75 and compare two doses of PG201 against a placebo over 8 weeks. However, the trial was withdrawn before any participants were enrolled, so no results are available.
