The study will be conducted in three parts. Part 1 is a dose escalation phase to determine the maximum tolerated dose (MTD) of INCB040093, a PI3Kδ inhibitor, or a tolerated, pharmacologically active dose; Part 2 will evaluate the combination of INCB040093 and itacitinib (INCB039110), a JAK1 inhibitor, to determine the MTD of the combination or a tolerated dose that produces substantial pharmacologic inhibition of both targets; Part 3 will further evaluate the chosen doses of INCB040093 alone and in combination with itacitinib (INCB039110) in subjects with relapsed/refractory B-cell malignancies.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Incyte Corporation (INCY) is the sponsoring company for this trial. BiotechSign currently grades this company F (35/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
