Multiple myeloma (MM) is characterised by generalised immune suppression, partly mediated by loss of T‐cell repertoire, inhibition of antigen‐presenting cells and increased expression of the inhibitory programmed death 1 (PD‐1, also termed PDCD1) immune checkpoint pathway, (Neri et al , 2016).

PD‐1 up‐regulation on T cells is associated with disease relapse and resistance to chemotherapy (Tamura et al , 2013), and blockade may represent a promising treatment option.

However, single‐agent PD‐1 inhibition did not show significant tumour regression, suggesting that combination therapy may be necessary (Lesokhin et al , 2016). In pre‐clinical studies, lenalidomide, an immunomodulatory drug (IMiD), plus PD‐1/PD‐L1 (CD274) blockade enhanced MM cell death induced by PD‐1/PD‐L1 immune checkpoint blockade alone (Gorgun et al , 2015).
