"They are small, powerful little nuggets. They are actually small signaling proteins that our immune cells use to communicate. They really help regulate immune activation or inflammation and even the growth and survival of immune cells. When cytokines are used therapeutically in oncology, they help to stimulate immune cells such as T cells or natural killer cells to better recognize and attack cancer cells," Maribel Pereiras, PharmD, BCPS, BCOP, clinical pharmacy specialist at the John Theurer Cancer Center of Hackensack University Medical Center in New Jersey, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing practice at ONS, during a conversation about the cytokine drug class.

Highlights From This Episode

"Cytokines are actually among some of the earliest forms of immunotherapy used in the treatment of cancer, and it really goes back to the 1980s and the 1990s. We're talking therapies like interferon [alpha] or interleukin-2 that were used to stimulate the immune system, with the idea that they would recognize and attack cancer cells, particularly in diseases like metastatic melanoma and renal cell carcinoma. What made these therapies unique was that although the overall response rates were relatively modest, when patients did respond, those responses could be very durable and sometimes long lasting. And that observation was really important for the field of oncology, because it was part of the process that demonstrated that the immune system could potentially control cancer in really meaningful ways." TS 1:49

"One nice new example of an engineered cytokine is nogapendekin alfa inbakicept, which is quite the tongue twister to say. … This agent is really interesting because it's an engineered interleukin-15 receptor agonist that works on stimulating natural killer cells and CD8-positive T cells. And what makes this so interesting is that it's used in combination with a medication that probably some of us are familiar with—good old BCG—for patients specifically with invasive bladder cancer. The other really interesting thing about this new therapy is the fact that it is one of our first ones to be engineered in a combination fashion. So the nogapendekin alfa is combined with a receptor component that is called inbakicept. And what happens is it forms a complex to enhance signaling and prolong the activity of the cytokine."
