The current phase I/IIa trial is a multi-center, prospective, open-label, ascending dose study to evaluate safety and biological efficacy of up to 3 dose levels of ODX. Each dose cohort will consist of 4 subjects. Each subject will receive up to 7 doses of ODX, given at 2-week intervals, until unacceptable toxicity or disease progression. A follow-up visit will be conducted 2 weeks after the last dose.
Primary objectives:
To determine the safety and tolerability of ODX in subjects with relapsed/refractory multiple myeloma.
Secondary objectives:
* To evaluate the preliminary efficacy of ODX, as determined by the IMWG response criteria, in subjects with relapsed/refractory multiple myeloma.
* To evaluate the efficacy of ODX on serum biomarkers (M-protein, FLC, CTX, osteocalcin, and bone-specific S-ALP) in subjects with relapsed/refractory multiple myeloma.
Exploratory objective
To evaluate time to progression by following M-protein and FLC levels as per clinical routine
