Recombinant Human Papillomavirus Nonavalent Vaccine in Preventing Human Papilloma Virus in Younger Healthy Participants
Active Not Recruiting
Human papillomavirus (HPV) is a common sexually-transmitted virus which causes infections that usually last only a few months, but sometimes can last a long time and cause cancers of the cervix, vagina, vulva, anus or oropharynx over many years among adults. This phase IIA trial studies how well does the nonavalent HPV vaccine (which can prevent nine different types of HPV) work when given in an alternative dosing schedule to heathy young research participants.

Testing a Combination of Vaccines for Cancer Prevention in Lynch Syndrome
Active Not Recruiting
This phase IIb trial tests whether Tri-Ad5 in combination with N-803 works to prevent colon and other cancers in participants with Lynch syndrome. Each of the three injections in Tri-Ad5 vaccine contain a different substance that is in precancer and cancer cells. Injecting these substances may cause the immune system to develop a defense against cancer that recognizes and destroys any precancer and cancer cells that produce these proteins in the future. N-803 may increase immune responses to oth... Read More
