Completed
This phase I trial studies the side effects and the best dose of nivolumab when given together with gene-modified T cells and vaccine therapy in treating patients with solid tumors that express the cancer-testes antigen NY-ESO-1 gene AND have spread from where it started to nearby tissue or lymph nodes (locally advanced) or distant organs (stage IV). T cells are a special type of white blood cells (immune cell) that have the ability to kill cancer cells. Nivolumab may block PD-1 which is found o... Read More

Testing the Addition of an Individualized Vaccine to Durvalumab and Tremelimumab and Chemotherapy in Patients With Metastatic Triple Negative Breast Cancer
Recruiting
This phase II trial studies how well nab-paclitaxel, durvalumab, and tremelimumab with or without personalized synthetic long peptide vaccine (neoantigen vaccine) works in treating patients with triple negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Chemotherapy drugs, such as nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopp... Read More

VGX-3100 and Electroporation in Treating Patients With HIV-Positive High-Grade Anal Lesions
Completed
This phase II trial studies the use of human papillomavirus (HPV) deoxyribonucleic acid (DNA) plasmids therapeutic vaccine VGX-3100 (VGX-3100) and electroporation in treating patients with human immunodeficiency virus (HIV)-positive high-grade anal lesions. Vaccines made from DNA may help the body build an effective immune response to kill tumor cells. Electroporation helps pores in your body's cells take in the drug to strengthen your immune system's response. Giving VGX-3100 and electroporatio... Read More

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.

P53MVA and Pembrolizumab in Treating Patients With Recurrent Ovarian, Primary Peritoneal, or Fallopian Tube Cancer
Active Not Recruiting
This phase II trial studies how well modified vaccinia virus ankara vaccine expressing p53 (p53MVA) and pembrolizumab work in treating patients with ovarian, primary peritoneal, or fallopian tube cancer that has come back (recurrent). Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the abili... Read More

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
