Description:
To evaluate the effects of treatment with ruxolitinib (INCB018424) on spleen volume, symptoms
and potential side effects in participants with PMF, PPV-MF and PET-MF who have platelet
counts of 50 x 10^9/L to 100 x 10^9/L. It is anticipated that individualized dose
optimization from the starting ruxolitinib level of 5 mg bid will be associated with
reductions in splenomegaly, MF-associated symptoms and inflammatory cytokine levels.

To evaluate the effects of treatment with ruxolitinib (INCB018424) on spleen volume, symptoms

Trial Arms
Name | Type | Description | Interventions |
---|
Ruxolitinib 5 mg | Experimental | Participants began administration with 5 mg ruxolitinib twice daily (BID) orally. Beginning at the Week 4 visit, doses of ruxolitinib could be increased in 5 mg once a day (QD) increments every 4 weeks every 4 weeks not to exceed a dose of 25 mg BID. | |

Primary Outcome Measures
Measure: | Percent Change From Baseline in Spleen Volume at Week 24 by Final Titrated Dose |
Time Frame: | Baseline and Week 24 |
Safety Issue: | |
Description: | Magnetic resonance imaging (MRI) of the upper and lower abdomen and pelvis was performed to assess spleen volumes. Computed tomography (CT) scan was performed if participant was not a candidate for MRI or if MRI was not readily available. MRI was performed with a body coil. Spleen volume was obtained by outlining the circumference of the organ and determining the volume using the validated technique of least squares. The MRI (or CT scan in applicable participants) was performed on the first or second day of the baseline period (ie, Day -7 or Day -6), and the site radiologist sent the scan to the central imaging laboratory that same day. The CT scans were processed by the same central laboratory used for MRIs. |
Secondary Outcome Measures
Measure: | Percent Change in Spleen Volume at Week 24 Compared to Baseline |
Time Frame: | Baseline and Week 24 |

Measure: | Percent Change in Total Symptom Score as Measured by the Modified MFSAF V2.0 Diary at Week 24 Compared to Baseline |
Time Frame: | Baseline and Week 24 |
Safety Issue: | |
Description: | Symptoms of myelofibrosis were assessed using a modified Myelofibrosis Symptom Assessment Form (MFSAF) Version 2.0 diary. Using the diary, patients rated the following symptoms on a scale from 0 (absent) to 10 (worst imaginable): night sweats, itching, abdominal discomfort, pain under ribs on left, feeling of fullness (early satiety), and muscle/bone pain. The total symptom score ranged from 0-60 and was calculated as the sum of the 6 symptom scores. A higher score indicates worse symptoms.. |
Measure: | Percentage of Participants With ≥ 35% Reduction in Spleen Volume at Week 24 Compared to Baseline |

Measure: | Change in Spleen Length Measured by Palpation |
Time Frame: | Up to Week 156 |
Safety Issue: | |
Description: | Measurement of spleen length below the left costal margin was measured by palpation at each study visit. Investigators were provided with a soft centimeter ruler so that palpable spleen length was measured in centimeters and not in finger breadths. The edge of the spleen was determined by palpation, and measured in centimeters, using a soft ruler, from the costal margin to the point of greatest splenic protrusion. |

Measure: | Patient Global Impression of Change (PGIC) Score at Each Visit |
Time Frame: | Up to Week 156 |
Safety Issue: | |
Description: | Symptoms of myelofibrosis were assessed using the PGIC questionnaire. Using the questionnaire, patients rated the overall sense of treatment effect on their symptoms on a scale of 1 (very much improved)- 7(very much worse). The specific wording was: Since the start of the treatment you've received in this study, your myelofibrosis symptoms are: 1) Very much improved, 2) Much improved, 3) Minimally improved, 4) No change, 5) Minimally worse, 6) Much worse, 7) Very much worse. A higher score indicates worse symptoms. |
