BACKGROUND: Omaveloxolone is a semisynthetic oleanane triterpenoid that potently
activates Nrf2 with subsequent antioxidant function. We conducted a
first-in-human Phase I clinical trial (NCT02029729) with the primary objectives
to determine the appropriate dose for Phase II studies, characterize
pharmacokinetic and pharmacodynamic parameters, and assess antitumor activity.
METHODS: Omaveloxolone was administered orally once daily continuously in a
28-day cycle for patients with stage 4 relapsed/refractory melanoma or non-small
cell lung cancer. An accelerated titration design was employed until a grade
2-related adverse event (AE) occurred. A standard 3+3 dose escalation was
employed. Single-dose and steady-state plasma pharmacokinetics of the drug were
characterized. Downstream Nrf2 activation was assessed in peripheral blood
mononuclear cells by quantification of target gene mRNA expression. RESULTS:
Omaveloxolone was tested at four dose levels up to 15 mg given orally once daily.
No dose-limiting toxicities were detected, and the maximum tolerated dose was not
determined. All drug-related AEs were either grade 1 or 2 in severity, and none
required clinical action. The most common drug-related AEs were elevated alkaline
phosphatase (18%) and anemia (18%). No drug interruptions or reductions were
required. Omaveloxolone was rapidly absorbed and exhibited proportional increases
in exposure across dose levels. With some exceptions, an overall trend toward
time-dependent and dose-dependent activation of Nrf2 antioxidant genes was
observed. No confirmed radiologic responses were seen, although one lung cancer
subject did have stable disease exceeding 1 year. CONCLUSIONS: Omaveloxolone has
favorable tolerability at biologically active doses, although this trial had a
small sample size which limits definitive conclusions. These findings support
further investigation of omaveloxolone in cancer.
