Pevonedistat in Combination With Ruxolitinib for Treatment of Patients With Myelofibrosis
Study Details
Study Description
Brief Summary
Based on the investigators' preclinical data, the combination of pevonedistat and ruxolitinib may provide greater clinical responses in patients with myelofibrosis compared to ruxolitinib monotherapy via inhibition of NFκB in addition to JAK-STAT signaling.

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Arm 1: Starting Dose - 5 mg/m^2 pevonedistat + ruxolitinib Pevonedistat will be given as an IV infusion at the assigned dose over the course of 60 minutes on Days 1, 3, and 5 of each 28-day cycle. Ruxolitinib will be continued at the same dose as prior to enrollment and will be administered as standard of care outside the study protocol. |
Drug: Pevonedistat
The amount of pevonedistat to be administered will be based on body surface area (BSA). BSA will be calculated using a standard formula on Cycle 1 Day 1, and on Day 1 of subsequent cycles if the patient experiences a > 5% change in body weight from the weight used for the most recent BSA calculation.
Other Names:
Drug: Ruxolitinib
-Standard of care outside of protocol
Other Names:
Procedure: Peripheral blood draw
Baseline or Cycle 1 Day 1 (prior to study treatment administration)
Cycle 2 Day 1 (prior to study treatment administration)
Cycle 4 Day 1 (prior to study treatment administration)
End of treatment
Procedure: Skin biopsy
A skin punch biopsy specimen will be collected at the baseline visit. One 6 mm punch biopsy of normal skin will be performed using standard techniques and local anesthesia.
|
| Experimental: Arm 2: Dose Level 2 - 10 mg/m^2 pevonedistat + ruxolitinib Pevonedistat will be given as an IV infusion at the assigned dose over the course of 60 minutes on Days 1, 3, and 5 of each 28-day cycle. Ruxolitinib will be continued at the same dose as prior to enrollment and will be administered as standard of care outside the study protocol. |

Outcome Measures
Primary Outcome Measures
- Safety and tolerability of pevonedistat in combination with ruxolitinib in patients with myelofibrosis as measured by the frequency of adverse events [Through 30 days after completion of treatment (estimated to be 42 weeks)]
-The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be utilized for all toxicity reporting.
- Safety and tolerability of pevonedistat in combination with ruxolitinib in patients with myelofibrosis as measured by the maximum tolerated dose (MTD) [28 days after enrollment of last participant (estimated to be 25 months)]
-MTD: The maximum tolerated dose (MTD) is defined as the dose level immediately below the dose level at which 2 patients of a cohort (of 2 to 6 patients) experience dose-limiting toxicity during the first cycle. Dose escalations will proceed until the MTD has been reached.
Secondary Outcome Measures
- Spleen response with the combination of pevonedistat and ruxolitinib [Through 12 weeks after completion of treatment (estimated to be 48 weeks)]
A baseline splenomegaly that is palpable at 5-10 cm below the left costal margin becomes not palpable OR A baseline splenomegaly that is palpable > 10 cm below the left costal margin decreases by ≥50% OR A baseline splenomegaly that is palpable < 5 cm below the left costal margin is not eligible for spleen response OR Ultrasound shows ≥35% spleen volume reduction (calculated)
- Improvement of constitutional symptoms with the combination of pevonedistat and ruxolitinib [Through completion of treatment (estimated to be 36 weeks)]
A ≥50% reduction in the myeloproliferative neoplasm symptom assessment total symptom score 8 symptoms (tiredness, early satiety, abdominal discomfort, inactivity, night sweats, itching, bone pain, pain under ribs under left side) with 0 to 10 ranking where 0=no pain and 10=worst imaginable pain
- Hematologic response with the combination of pevonedistat and ruxolitinib as measured by anemia response [Through 12 weeks after completion of treatment (estimated to be 48 weeks)]
-Anemia response is only applicable for patients with a baseline hemoglobin level less than 10g/dL for 8 weeks or more, and requires: ≥ 2 g/dL increase in hemoglobin level OR becoming transfusion-independent (no RBC transfusions in past 1 month)
- Hematologic response with the combination of pevonedistat and ruxolitinib as measured by platelet response [Through 12 weeks after completion of treatment (estimated to be 48 weeks)]
-Platelet response is only applicable for patients with a baseline platelet count of less than 50 x 109/L for 8 weeks or more, and requires: 100% increase in platelet count AND An absolute platelet count of at least 50 x 109/L
- Pharmacokinetics of pevonedistat when co-administered with ruxolitinib as measured by the Cmax (peak serum concentration) [Through Cycle 1 Day 5]
- Pharmacokinetics of pevonedistat when co-administered with ruxolitinib as measured by the Tmax (time of maximum concentration observed) [Through Cycle 1 Day 5]
- Pharmacokinetics of pevonedistat when co-administered with ruxolitinib as measured by the area under the plasma drug concentration curve (AUC) [At 24 hours]
-AUC reflects the actual body exposure to drug after administration of a dose of the drug and is expressed
