As of my last update in January 2022, several immunotherapy drugs have been studied or are currently being investigated for the treatment of prostate cancer. Here are some of the notable ones:
Sipuleucel-T (Provenge): Sipuleucel-T is an autologous cellular immunotherapy approved for the treatment of asymptomatic or minimally symptomatic metastatic castration-resistant prostate cancer (mCRPC). It is designed to stimulate the patient's immune system to target and attack prostate cancer cells.
Pembrolizumab (Keytruda): Pembrolizumab is a checkpoint inhibitor that targets PD-1 (programmed cell death protein 1). While not specifically approved for prostate cancer, pembrolizumab has been studied in clinical trials for advanced prostate cancer, particularly in patients with mismatch repair deficiency (dMMR) or microsatellite instability-high (MSI-H) tumors.
Nivolumab (Opdivo): Nivolumab is another checkpoint inhibitor that targets PD-1. Like pembrolizumab, nivolumab has been studied in clinical trials for advanced prostate cancer, often in combination with other therapies.
Ipilimumab (Yervoy): Ipilimumab is a checkpoint inhibitor that targets CTLA-4 (cytotoxic T-lymphocyte-associated protein 4). It has been investigated in combination with other immunotherapies or with conventional treatments for prostate cancer in clinical trials.
Atezolizumab (Tecentriq): Atezolizumab is a checkpoint inhibitor that targets PD-L1 (programmed death-ligand 1). It has been studied in combination with other therapies for advanced prostate cancer in clinical trials.
Durvalumab (Imfinzi): Durvalumab is another checkpoint inhibitor that targets PD-L1. It has been explored in clinical trials for various cancers, including prostate cancer, typically in combination with other treatments.
These are some of the immunotherapy drugs that have been studied or are currently being investigated for prostate cancer treatment. It's important to note that while some of these drugs have shown promise in clinical trials, not all of them have been approved specifically for prostate cancer by regulatory agencies like the FDA. Additionally, ongoing research may lead to the identification of new immunotherapy drugs or combination therapies for prostate cancer treatment in the future.
