NCT02570997

Brief Summary

This is a double-blind, placebo controlled, ascending dose, multi-cohort trial. The study will be conducted in two phases: a single ascending dose (SAD) phase "Part A", followed by a multiple ascending dose (MAD) phase "Part B". In Part A, subjects will receive one dose of study drug. In Part B, subjects within a cohort will receive the same dose daily for 14 days. In both parts, sequential cohorts will be exposed to increasing doses of CT1812 in order to identify the maximum tolerated dose (MTD).

Outcome Measures

Primary Outcomes (1)

  • Incidence and review of Treatment Emergent Adverse Events [Safety and Tolerability]

    Treatment Emergent Adverse Events will be assessed by reviewing: * physical examinations, * monitoring vital signs, * monitoring clinical and laboratory assessments, * monitoring ECGs.

    up to 35 days

Study Arms (2)

CT1812

ACTIVE COMPARATOR

In cohorts 1-6, 8 subjects will be enrolled. 6 subjects will receive CT1812. Doses will be escalated in the following sequence: 10mg, 30mg, 90mg, 180mg, 360mg, 650mg. Should an MTD not be identified, additional cohorts at higher doses may be enrolled. The maximum dose administered will not exceed 1350mg.

Drug: CT1812
