Which of the Following Drug Is Most Likely to Have a Synergistic Effect When Combined With Radiation Therapy?

February 01, 2019

The Answer

The answer is D. Ipilimumab. 

Amifostine, pentoxifylline, and palifermin are all types of radioprotectants.   

Ipilimumab is a CTLA-4 inhibitor that has shown promise in clinical trials to improve some patients’ response to radiation therapy. Several recent trials have suggested that combining radiation with immunotherapy, primarily checkpoint inhibitors, may have a synergistic effect on metastatic melanoma by preventing tumor cells from evading the immune response through several mechanisms.
