What are the common side effects of nivolumab treatment?
Nivolumab, an immune checkpoint inhibitor, can cause a range of side effects due to its mechanism of action, which involves disrupting the interaction between cancer cells and the immune system [1]. One of the known side effects of nivolumab is skin reactions, including pruritus (itching) and dermatitis [2].
Can hives develop as a side effect of nivolumab?
Yes, hives (urticaria) have been reported in patients treated with nivolumab [3]. According to the FDA-approved label for nivolumab, skin reactions, including urticaria, may occur in up to 16% of patients receiving the treatment [4].
Why are skin reactions a concern in nivolumab treatment?
Skin reactions can range from mild to severe, and in some cases, can be life-threatening. In a clinical trial, approximately 3% of patients treated with nivolumab experienced Grade 3 or higher skin reactions, which required treatment discontinuation [5].
What should patients do if they experience hives or other skin reactions while on nivolumab?
If patients experience any skin reactions, including hives, while on nivolumab, they should inform their healthcare provider immediately. In some cases, mild skin reactions can be managed with antihistamines or topical corticosteroids, while more severe reactions may require treatment discontinuation or hospitalization [6].
Can biosimilars affect the risk of hives development in nivolumab?
The risk of hives development associated with nivolumab is not yet fully understood, and further research is needed to determine whether biosimilars will have a similar risk profile [7]. Patients using nivolumab or biosimilar alternatives should closely monitor their skin and report any unusual reactions to their healthcare provider.
