Brief summary
The purpose of this open-label, single arm, multi-center Expanded Treatment Protocol (ETP) was to provide early access to ruxolitinib and evaluate safety information in patients with polycythemia vera (PV) who were hydroxyurea (HU) resistant or intolerant and who had no other standard treatment option, nor did they qualify for another clinical study for PV
Interventions
supplied as 5 mg, 10 mg and 20 mg tablets to be taken orally

Eligibility
Inclusion criteria
•Confirmed diagnosis of PV according to the 2008 World Health Organization criteria, palpable spleen, Resistant to or intolerant of hydroxyurea, ECOG performance status of 0, 1 or 2; did not have access to a comparable or satisfactory alternative treatment
Exclusion criteria
•Inadequate liver or renal function, Significant bacterial, fungal, parasitic, or viral infection requiring treatment, Active malignancy within the past 5 years, except treated cervical intraepithelial neoplasia, basal cell carcinoma of the skin, or squamous cell carcinoma of the skin, with no evidence for recurrence in the past 3 years., Women who were pregnant or nursing.

| Change From Baseline in Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score (MPN-SAF TSS) | Up to approximately 26 months | The MPN-SAF (Appendix 6) was a disease specific questionnaire comprised of 10 items that measures fatigue related to MPN disease and the severity of nine of the most prevalent associated symptoms including: early satiety, abdominal discomfort, inactivity, concentration, night sweats, itching, bone pain, fever and weight loss. There were three recall periods used in this questionnaire, which were 24 hours for fatigue, the past week for symptoms of early satiety, abdominal discomfort, inactivity, concentration, night sweats, itching, bone pain and fever, and the past 6 months for weight loss, Each item was scored on a scale ranging from 0 (no fatigue/absent) to 10 (As bad as you can imagine/worst imaginable). The MPN-SAF TSS was computed as the average of the observed items multiplied by 10 to achieve a 0-to-100 scale. The MPN-SAF TSS thus had a possible score range of 0 to 100. |
