A Study to Assess Safety and Tolerability of PCRX-201 in Subjects With Painful Osteoarthritis of the Knee
Recruiting
The goal of this clinical trial is to learn if a single knee injection of different doses (Dose A and Dose B) of an investigation product PCRX-201, following steroid pretreatment, is safe and tolerable in male of female patients 45 to 80 years old with osteoarthritis of the knee. It will also learn how the body reacts to the PCRX-201 injection and how effective the treatment is. Researchers will compare Dose A and Dose B of PCRX-201 versus placebo from Week 1 through Week 52 to assess adverse e... Read More
