About this study

Background: Throat cancer is a common tumor that can occur in people infected with the human papilloma virus (HPV). Most people with this cancer survive more than 5 years with standard chemotherapy drugs plus radiation. But radiation can cause serious adverse effects. Researchers believe that adding a vaccine (PRGN-2009) to this drug therapy may improve survival without the need for radiation. Objective: To test a study vaccine combined with standard chemotherapy in patients with HPV-associated throat cancers. Eligibility: People aged 18 years and older with newly diagnosed throat cancer associated with HPV. Design: Participants will be screened. They will have a physical exam and blood tests. They will have imaging scans and tests of their heart function and hearing. They will provide a sample of tissue from their tumor. A recent sample may be used; if none is available, a new sample will be taken. All participants will get two common drugs for treating cancer. These drugs are given through a tube attached to a needle inserted into a vein in the arm. Participants will receive these drugs on the first day of three 3-week cycles. Half of the participants will also get the vaccine. PRGN-2009 is injected under the skin in the arm. They will get these shots 4 times: 7 days before the start of the first cycle and on the 11th day of each cycle. Participants will have standard surgery to remove their tumors 3 to 6 weeks after completing the study treatment. They will have …
