Interventions
NameTypeDescription
ITU512DRUGITU512 is an investigational, oral, low molecular weight (LMW) compound.
PlaceboDRUGAn inactive substance that looks like and is given the same way as ITU512. The effect(s) of ITU512 will be evaluated against the placebo. Placebos are designed as a control and to have no real effect.
