Primary purpose: OTHER

Brief summary: This is a first-in-human, phase 1, single centre, placebo-controlled, double-blind, single ascending dose study of LEVI-04 in heathy volunteers and osteoarthritis patients (with pain attributed to osteoarthritis of the knee)

Detailed description: There will be 8 cohorts of 7 subjects each. Cohorts 1-3 and 8 will be composed of healthy volunteers. Cohorts 4-7 will be composed of osteoarthritis patients. Cohort 4 will be a bridging cohort; osteoarthritis patients in Cohort 4 will receive the same dose as the healthy volunteers in Cohort 3, if deemed safe.

Each subject will be assigned to receive a single dose of LEVI-04 or matching placebo. Each dose will be administered as an intravenous infusion over 30 minutes. Planned doses will start at 0.003 mg/kg in Cohort 1, and may be increased to 3.0 mg/kg in Cohort 8. The planned doses may be changed, depending on the safety, tolerability and pharmacokinetic results after previous doses. The dose selected for each cohort will be determined by the Safety Review Team, following review of all available pharmacokinetic and safety data. For each escalating dose, there will be at least 2 weeks between the start of each cohort (at least 14 days between Day 0 for the last subject in the previous cohort and Day 0 for the first subject in the subsequent cohort), to allow for review of safety, tolerability and pharmacokinetic data. In each cohort, 5 subjects will receive LEVI-04 and 2 subjects will receive matching placebo.
