Small immunotherapy studies in high-risk patients
FIG. 43: Studies of other immunotherapies studies have been relatively small. Two drugs are unfortunately no longer being investigated. Bropirimine, an oral interferon inducer, produced some promising results,[29,30] but development of this drug was stopped. Imiquimod, a toll-like receptor 7 (TLR-7) agonist, was shown to be safe and relatively effective after intravesical administration in a Phase 1 trial,[31] but development of this formulation of the drug was also terminated.
