Episode 403: Pharmacology 101: Checkpoint Inhibitors

"Because the premise of immune checkpoint blockade centers around elevating the immune function, we should always take a great deal of caution around those patients who have high immune risks. Those include patients with autoimmune disorders. That's one of our biggest questions that we ask, usually every consult that we're seeing with solid tumor. 'Do you have any history of autoimmune disorders? Tell me a little bit more about it. Is it being treated? What are your symptoms like?' And then also patients who have undergone organ transplants. Now, interestingly, this does include stem cell transplants," Kelsey Finch, PharmD, BCOP, oncology pharmacist practitioner at Columbus Regional Health in Indiana, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing practice at ONS, during a conversation about checkpoint inhibitors.

Highlights From This Episode "Before immune checkpoint blockade, the two-year overall survival rate in metastatic melanoma was hovering around 10%. After these agents came to market, depending on the trial and the agents used, that number actually increased to about 50%–65%. So, five times the amount of patients were actually living at the two-year mark. Not surprisingly, studies then exploded across several tumor types, leading to approvals in all sorts of cancers, mostly in the solid tumor. But there are a couple hematologic as well. Lung cancer, kidney cancer, head and neck, Hodgkin lymphoma, hepatocellular, the list goes on. So, it's really just transforming the stage IV setting across all tumors, specifically from uniformly fatal prognosis to one where durable responses and long-term survival is also possible." TS 3:03 "There are four different mechanisms officially being used in therapies that are approved by the U.S. Food and Drug Administration (FDA). Those are cytotoxic T-lymphocyte–associated protein 4, programmed cell death protein 1, and programmed cell death ligand 1, which I'm counting as two different mechanisms, even though they somewhat work together. And lymphocyte-activation gene 3 is the fourth one that's in there. So, all these mechanisms impact the T cell in our immune system. The T cell is traditionally responsible for protecting our body from harmful things like ...
