• Radiotherapy within 2 weeks of the first dose of study drug
• Use of hematopoietic colony-stimulating growth factors (eg, G-CSF, GM-CSF, M-CSF) ≤ 2 weeks prior to start of study drug.
• Male patients must be surgically sterile or use double barrier contraception methods from enrollment through treatment and for 6 months following administration of the last dose of study drug
• Contraindication for treatment with Investigator’s Choice alternatives (dacarbazine, ipilimumab and pembrolizumab) as per applicable labelling.

Other illness
