Study Details

Study Description

Brief Summary

This study will evaluate the safety and tolerability of oral KPT-9274 for the treatment of patients with relapsed or refractory acute myeloid leukemia.

Detailed Description

KPT-9274 is a first-in-class orally bioavailable, non-competitive, small molecule, dual modulator of p21 protein (Cdc42/Rac)-activated kinase 4 (PAK4) and nicotinamide phosphoribosyltransferase /PBEF/visfatin (NAMPT). NAMPT is the rate-limiting enzyme in the metabolic scavenging pathway that utilizes nicotinamide to replenish nicotinamide adenine dinucleotide (NAD), an essential metabolic cofactor and second messenger. Recent investigations have shown that in in vitro and in vivo models, NAMPT is uniquely essential for relapsed or refractory AML stem cells. Targeting relapsed AML stem cells, through targeting of NAMPT, may allow for a promising therapeutic opportunity for patients with relapsed or refractory AML.

Study Design

Study Type:
Interventional
Anticipated Enrollment :
40 participants
Allocation:
Non-Randomized
Intervention Model:
Sequential Assignment
Intervention Model Description:
During dose escalation, patients will receive oral KPT-9274 three times a week every other day (Days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, and 26) during each 28-day cycle, and the first dose cohort will be 30 mg. Subsequent dose escalation cohorts, as well as a de-escalation cohort, will be administered. Dose escalation will continue until the MTD is determined. The MTD is defined as the highest dose at which ≤1 patient experiences a DLT in Cycle 1. A RP2D equal to or less than the MTD will be declared and used for the Dose Expansion Phase, if conducted.During dose escalation, patients will receive oral KPT-9274 three times a week every other day (Days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, and 26) during each 28-day cycle, and the first dose cohort will be 30 mg.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: De-escalation Cohort; 20mg

For the purposes of dose escalation decisions, a standard 3+3 dose escalation design will be used.The initial cohort, Cohort 1, will consist of 3 enrolled patients who will be treated at 30 mg. If the MTD is exceeded at cohort 1, de-escalation to cohort 0 (20 mg) will occur. If the MTD is not exceeded in cohort 1, dose escalation will continue based on a standard 3+3 design at the dose levels.

Outcome Measures

Primary Outcome Measures

  1. Maximum Tolerated Dose (MTD) [28 days]

    Dose escalation will continue until the MTD is determined. The MTD is defined as the highest dose at which ≤1 patient experiences a DLT in Cycle 1.

Secondary Outcome Measures

  1. Establish Recommended Phase 2 Dose (RP2D) [28 days]

    A RP2D equal to or less than the MTD will be declared after the MTD is determined and will be used for the Dose Expansion Phase, if conducted. After the RP2D is determined, a dose expansion phase, of up to 10 additional patients, might be conducted, in which a preliminary determination of efficacy will be conducted, using the ELN criteria.
