Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purposes of this trial are: * To evaluate the toxicity and tolerability of QBI-139 in patients with advanced refractory solid tumors. * To determine the maximum tolerated dose of QBI-139 in patients with advanced, refractory solid tumors.
