About

This first in human phase 1 study to Study will evaluate safety, tolerability, and pharmacokinetics of Single Ascending dose (SAD), Food effect (FE) and Multiple ascending dose (MAD) of OR-101 Administered Orally in healthy subjects

Full description

There are three phases of the study: Single ascending dose (SAD), food effect (FE), and multiple ascending dose (MAD) phases.

In the SAD and MAD Phases, up to 64 subjects in each phase may be enrolled in the study. Fortyeight subjects will be randomised in the initial six cohorts; upto 16 subjects may be enrolled in two additional cohorts. For each dose cohort a total of 8 subjects (6 receiving OR-101 and 2 placebo) will be enrolled and randomized.

In the FE phase, up to 8 subjects who will receive a high fat meal prior to administration of OR101 may be enrolled in the study. Subjects who discontinue prior to completion may be replaced at the discretion of the Sponsor and the Investigator.

The SRC including the Investigator, Medical Monitor, Study Director as well as other ad hoc representatives as appropriate will regularly monitor all aspects of subject safety throughout this study. The SRC will review all available, cumulative safety and PK data in a blinded manner to assess the safety of each dose level of OR-101 prior to escalating to the next dose level.
