How does Adstiladrin work against cancer?
Adstiladrin (nadofaragene firadenovec) is a gene therapy designed to get bladder cancer cells to make an anti-cancer immune signal. It’s delivered as a viral vector into the bladder using a catheter, then enters bladder tumor cells to deliver a gene that prompts production of interferon alfa-2b. Interferon helps activate immune responses that can slow or shrink tumors.
What happens after it’s put into the bladder?
After treatment, the vector introduces the gene locally in the bladder. The goal is for tumor cells to start expressing interferon alfa-2b in the local area, which can stimulate immune attack on the cancer. Because the therapy is delivered directly into the bladder, its intended effect is concentrated in the bladder rather than systemic circulation.
Is Adstiladrin like chemotherapy or like immunotherapy?
It’s not a traditional chemotherapy drug because it does not directly poison rapidly dividing cells. It also works differently from standard immunotherapies that already contain an immune-activating agent. Instead, Adstiladrin is a gene therapy that causes cells to produce an immune-stimulating protein (interferon alfa-2b) as part of its anti-tumor effect.
What cancer type is it used for (and why that matters to how it treats)?
Adstiladrin is used for bladder cancer, and its delivery method (into the bladder) matches that biology: the therapy’s mechanism depends on local transfection of bladder cells and local interferon production to support an immune response against bladder tumors.
