A Study to Assess Adverse Events, Change in Disease Activity, and How the Drug Moves Through the Body in Children With Juvenile Psoriatic Arthritis (jPsA) Receiving Subcutaneously Injected Risankizumab or Adalimumab
Recruiting
Psoriatic arthritis (PsA) is a type of arthritis that happens when the body's immune system attacks healthy cells and tissues causing joint pain, stiffness, and swelling. Symptoms can get worse and go away for periods of time. PsA that begins before a patient's 16th birthday is called juvenile PsA (jPsA).This study will evaluate how safe risankizumab is for the treatment of psoriatic arthritis and to assess change in disease symptoms. Risankizumab is being studied for the treatment of jPsA and... Read More

PReclude Infection EVEnts With No Prophylaxis Transperineal Biopsy 2
Recruiting
Approximately one million transrectal prostate biopsies are performed annually in the U.S., and the risk of post- biopsy infection is increasing due to greater antibiotic resistance of rectal flora. Preliminary data demonstrates that a transperineal MRI-targeted biopsy approach under local anesthesia compared to the standard practice transrectal MRI-targeted prostate biopsy has a much lower risk of infection, comparable pain/discomfort and may improve detection of prostate cancer. This randomiz... Read More
