Cancer Vaccine

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 follow-up visits 3, 6, 12, and 24 months after their surgery. ...

This project intends to carry out phase I clinical studies on the basis of the previous work, initially exploring the possible effective dose, evaluating its safety and tolerability, with a view to achieving long-term control of the disease, which is expected to provide more options for the treatment of patients with advanced malignant solid tumors. The development of this project will provide new ideas, strategies and theoretical basis for the research and development of whole tumor cell vaccines; at the same time, it is expected to obtain original new drugs with independent intellectual property rights.
