An erythroid-stimulating agent is allowed as long as it was initiated at least 3 weeks prior to the first dose of study treatment and the patient is not red blood cell (RBC) transfusion dependent. For more information on the timing and use of hematopoietic colony-stimulating growth factors during study.

Highly effective methods of contraception are described in Section 4.12.
          • 24. Male patients must be surgically sterile or use double barrier contraception methods as described in Section 4.12 from enrollment through treatment and for 6 months following administration of the last dose of Tebentafusp.
