MRCP001Study Participants
40This project represents a first systematic, prospective, single-arm cohort study of a safe and effective dosing regimen of an orally administered cannabis oil formulation in a cancer subject population with poorly controlled pain.
Over a 1-2 year period, 40 cancer patients experiencing poorly controlled pain will be enrolled in to a prospective single-arm cohort study, in which they will receive an orally administered cannabis oil formulation as an add-on therapy to current treatment regimens. Subjects entering the acute study phase will be titrated to a tolerated dose at which a sustained pain response is reached, and may subsequently enter a 12 week chronic phase during which safety and durability of pain response will be assessed at their stable dose.
MRCP001 administered per protocol dose titration regimen (beginning at 1 capsule daily, titrated to a maximum of 3 capsules BID)
