Arm 1: Lysate Pulsed Dendritic Cells (PV-001-DC) in Patients With Melanoma
brief summary
Autologous monocyte-derived dendritic cells pulsed with tumor lysate (PV-001-DC) will be given to a group of 3 people. If this is found to be safe, it will be given to up to 7 other people, for a total of up to 10 people in this arm. This will be the first study of PV-001-DC. Eligible patients must be progressing after having completed prior therapy with a PD-1/PD-L1 antagonist alone or in combination with anti-CTLA-4. If the patient is positive for BRAF, the patient must have progressed on at least one BRAF inhibitor in addition to a PD-1/PD-L1 inhibitor alone or in combination with CTLA-4 for metastatic melanoma. Although other kinds of dendritic cells (DCs) have been approved to treat some forms of cancer, they have not been approved to treat melanoma. PV-001-DC is a special kind of DCs that is combined with tumor lysate. The study procedures will start with the removal of a small amount of tumor tissue processed into protein fragments (lysate). There will also be collection of white blood cells through apheresis (a procedure in which blood is drawn from a patient and separated into its different cell types), the white blood cells will be collected and the remainder returned to the patient. Dendritic cells will be grown from the collected white blood cells and combined with the lysate to form PV-001-DC. On the first day of study treatment, patients will go to the clinic and have a needle placed in a vein. The PV-001-DC product will be infused into the patient's vein. Approximately every 3 weeks, for a total of 4 treatments, patients will receive additional infusions of PV-001-DC. Patients will be at the clinic for at least 1 hour following the end of the PV-001-DC infusion and if they feel fine, they may go home. Scans will be performed during the study at different times to see if their tumors have changed in size. Patients will also have their blood and small samples of tumors tested for changes to the immune system. After 365 days, the trial will be completed for that patient. Investigators will monitor patients carefully for any harmful side effects. The side effects in people cannot be completely known ahead of time
