Ankara, YenimahalleAges 6–18 - NCT07281430Recruiting
HPV self-test for cervical cancer screening
This study tests if a self-collected sample for HPV testing works as well as standard colposcopy to prevent cervical cancer. If you've recently had an abnormal cervical cancer screening and need a colposcopy, this trial may be an option for you.
Birmingham, AlabamaAges 25 years+ - NCT07100990RecruitingPhase 3
Early plasma exchange for optic neuritis or myelitis
This trial tests if getting plasma exchange early, along with high-dose steroids, helps people with severe optic neuritis or transverse myelitis recover better than waiting to see if steroids alone work. It aims to find out if faster treatment can prevent lasting vision loss or disability.
