This is an open-label, single-sequence, three-period drug-drug interaction study in healthy male and female volunteers to evaluate the effect of a potent CYP3A inhibitor, ritonavir or cobicistat, on the single dose PK of orally administered PBI-200. It is expected that co-administration of ritonavir or cobicistat with PBI-200 will increase the exposure of PBI 200.
This is a drug-drug interaction study in volunteers to evaluate the effect of ritonavir or cobicistat on the pharmacokinetics (PK) of PBI-200.
