About
This phase Ib/II trial studies how well dendritic cell therapy after cryosurgery in combination with pembrolizumab works in treating patients with stage III-IV melanoma that cannot be removed by surgery. Vaccines made from a person's white blood cells mixed with tumor proteins may help the body build an effective immune response to kill tumor cells. Cryosurgery, also known as cryoablation or cryotherapy, kills tumor cells by freezing them. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells. Giving dendritic cell therapy after cryosurgery in combination with pembrolizumab may work better in treating patients with melanoma.
Full description
PRIMARY OBJECTIVES:
I. To determine the objective response rate (ORR) of pembrolizumab combined with cryoablation and intratumoral mature dendritic cells (mDCs) in patients with metastatic melanoma that has failed to respond or has stopped responding to initial therapy with a PD-1 axis-blocking monoclonal antibody.
SECONDARY OBJECTIVES:
I. To assess the safety profile of pembrolizumab combined with cryoablation and intratumoral mDCs in patients with metastatic melanoma that have failed to respond or have stopped responding to initial therapy with a PD-1 axis-blocking monoclonal antibody.
II. To determine median progression-free survival (PFS) obtained with this approach in this patient population.
III. To determine median overall survival (OS) obtained with this approach in this patient population.
TERTIARY OBJECTIVES:
I. To quantitate tumor infiltrating lymphocytes (TILs) in tumor biopsies prior to and following cryoablation and intratumoral mDCs.
II. To measure PD-L1 levels in tumor biopsies and blood biopsies prior to and following cryoablation and to assess whether a change in PD-L1 levels differ among those patients who met the criteria for clinical benefit (progression-free and on study for at least 6 months) and those who do not.
III. To measure peripheral blood mononuclear cells (PBMC) proliferation and function after coculture with frozen tumor before and after intratumoral mDC injection.
OUTLINE:
Patients undergo apheresis over 4 hours on day 1 or course 1. Patients also receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Courses with pembrolizumab repeat every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Within 36 hours after receiving pembrolizumab, patients undergo cryosurgery over 45 minutes on day 1 or 2 of courses 2 and 3. Patients also receive mature dendritic cells intratumorally (IT) on day 1 or 2 of courses 2 and 3 after cryosurgery.
After completion of study treatment, patients are followed for up to 5 years
