Giv­en the eth­i­cal chal­lenges of us­ing a place­bo in ran­dom­ized con­trolled clin­i­cal tri­als for ther­a­pies to treat hema­to­log­ic ma­lig­nan­cy and on­co­log­ic dis­ease, the FDA rec­om­mends that a spon­sor use a place­bo-con­trolled de­sign on­ly in se­lect cir­cum­stances, ac­cord­ing to new draft guid­ance re­leased Thurs­day.

Such cir­cum­stances in­clude “where sur­veil­lance is stan­dard of care,” or with spe­cif­ic tri­al “de­sign fea­tures (e.g. if the tri­al us­es an add-on de­sign, when the end­point in­tend­ed to sup­port a la­bel­ing claim has a high de­gree of sub­jec­tiv­i­ty, such as pa­tient re­port­ed out­comes).”
