Nivolumab Hypersensitivity Reactions a Myth or Reality in Solid Tumors—A Systematic Review of the Literature

TLDR: In this article , the authors sought to identify the answers to four questions: 1. what type of cancer has more severe hypersensitivity reactions to Nivolumab, 2. what is the time frame for developing these severe reactions to nivolumaab, 3. whether it is best to continue or stop the treatment after a severe hypersensitive reaction to NIVolumaba, and 4. what severe hypersensation reactions are the most frequent reported along Nivilumab treatment.

Abstract: Immune-checkpoint inhibitors (ICIs) are the most effective treatments nowadays. Nivolumab was the second ICI used for treating solid tumors with amazing results. Patients treated with Nivolumab may react differently to this treatment. Some people tolerate this treatment very well without experiencing any adverse reactions, whilst some may have mild symptoms and a part of them can present severe reactions. In our research, we sought to identify the answers to four questions: 1. what type of cancer has more severe hypersensitivity reactions to Nivolumab, 2. what is the time frame for developing these severe reactions to Nivolumab, 3. whether it is best to continue or stop the treatment after a severe hypersensitivity reaction to Nivolumab and 4. what severe hypersensitivity reactions are the most frequent reported along Nivolumab treatment. This review also highlights another problem with regard to the usage of concomitant and prior medications or other methods of treatment (e.g., radiation therapy), which can also lead to severe reactions. Treatment with Nivolumab is very well tolerated, but patients should also be warned of the possibility of severe hypersensitivity reactions for which they should urgently see a doctor for a personalized evaluation. There are some options for individuals with severe hypersensitivity reactions, for eg. switching the medication or applying a desensitization protocol.
