Abstract

OPB‑111077 is a novel, highly specific oral signal transducer and activator of transcription 3 inhibitor that has exhibited good efficacy against solid and blood cancers, including acute myeloid leukemia (AML), in preclinical models. In the present study, a phase 1b, two‑stage, 3+3 dose‑escalation clinical trial [dose level (DL)1 of 200 mg/day and DL2 of 250 mg/day on a once daily dose schedule in 28‑day cycles] was conducted to assess the maximum tolerated dose (MTD), safety profile and the preliminary antitumor activity of OPB‑111077 in patients with high‑risk AML. A preliminary preclinical analysis evaluated the anti‑proliferative activity of OPB‑111077 in 19 patients with AML with a Vivia Biotech ex vivo PharmaFlow precision medicine test. A total of 12 patients were ultimately enrolled in the trial: 5 patients (42%) were treated with DL1, and 7 (58%) were escalated to DL2 of OPB‑111077. Dose‑limiting toxicities were not observed and the MTD was not reached. In addition, the most frequently reported treatment‑emergent adverse events were nausea, vomiting and fatigue. Finally, clinical activity (overall response) was observed in 3 patients (25%). On the whole, the present study demonstrates that OPB‑111077 exhibits a good safety and tolerability profile and an acceptable clinical response in patients with high‑risk AML. A biomarker‑driven design is useful for selecting the study population upfront.
