A clinical research study to find out if the drug ruxolitinib (also known as INC424) is safe and has beneficial effects in people who have Polycythemia Vera (PV), a blood disease where your body makes too many red blood cells and sometimes too many white blood cells.

Randomized, open label, multicenter phase IIIb study evaluating the efficacy and safety of ruxolitinib versus best available therapy in patients with polycythemia vera who are hydroxyurea resistant or intolerant - Response 2

Eligibility

Inclusion criteria

Inclusion criteria: 1.Confirmed diagnosis of PV according to the revised World Health Organization (WHO) criteria 2. Non palpable spleen at screening and baseline 3. Hct requirement: a. A Hct between 40 and 45% inclusive within 14 days of Baseline, and: ? at least 2 phlebotomies within the 24 weeks prior to Screening, and ? the 2 phlebotomies are at least 4 weeks apart. Or, b. Hct > 45% and ? required at least one phlebotomy within the 16 weeks prior to Screening ? Must go through the Hct control period to achieve an Hct level between 40 and 45% inclusive within 14 days of Baseline. 4. Patients must have a treatment history for PV that meets the definition of resistance or intolerance to hydroxyurea (HU) by exhibiting at least one of the following criteria (with response modified from Barosi et al 2009a): ? HU Resistance: defined after 12 weeks into a course of HU therapy at a dose of at least 2 grams/day or at the patient?s maximally tolerated dose if that dose is less than 2 grams/day: 1. Need for phlebotomy to keep Hct 2. Platelet count > 400 x 109/L AND white blood cell count > 10 x 109/L, or ? HU Intolerance: 1. Absolute neutrophil count hemoglobin a response as defined below (modified from Barosi et al 2009b): ? Hct - platelet count = 400 x 109/L, - white blood cell count = 10 x 109/L, - and non-palpable spleen, or 2. Presence of leg ulcers or other unacceptable HU-related non-hematological toxicities (such as mucocutaneous manifestations, gastrointestinal symptoms, pneumonitis or fever at any dose of HU), defined as: ? severe AE that significantly impacted daily activities (equivalent to CTCAE version 4.0 Grade 3-4), or ? more than 1 week of a moderate AE that impacted some daily activities (equivalent to CTCAE version 4.0 Grade 2), or ? permanent discontinuation of HU, or ? interruption of HU until toxicity resolved, or ? hospitalization due to HU toxicity. If the patient meets the definition for both resistance and intolerance, they will be considered resistant for stratification purposes. 5. ECOG performance status of less than or equal to 2 at Screening and Baseline.

Exclusion criteria

Exclusion criteria: Lab abnormalities 1. Inadequate liver or renal function at screening as demonstrated by: ? Hepatic encephalopathy Grade 2 or more, ? Hepatocellular disease (for example, hepatitis B or C, cirrhosis), ? Direct bilirubin = 2 ? Upper Limit Normal (ULN). Direct bilirubin should be measured if total bilirubin is greater than 2 ? ULN, ? Alanine aminotransferase (ALT) greater than 2.5 ? ULN, ? Modification of Diet in Renal Disease estimate glomerular filtration rate (MDRDeGFR) less than 30 mL/min/1.73m2 or on dialysis, 2. Platelet count less than 100 ?109/L or an Absolute Neutrophil Count (ANC) less than 1 ? 109/L at screening. 3. Peripheral blood blast count greater than 0% at screening. Concurrent diseases 4. Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of oral ruxolitinib (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, small bowel resection). 5. Clinically significant bacterial, fungal, parasitic or viral infection which require therapy: ? For acute bacterial infections requiring antibiotic use, screening/enrollment should be delayed until the course of antibiotic therapy has been completed. ? Known active hepatitis A, B or C at Screening or with known HIV positivity. ? Diagnosed primary immunodeficiency syndromes such as X-Linked Agammaglobulinemia and Common Variable Immune Deficiency 6. Active malignancy over the previous 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. 7. Clinically significant cardiac disease (NYHA Class III or IV;), or thromboembolic event within the past 6 months. 8. History of progressive multifocal leukoencephalopathy (PML) 9. Patients with any concurrent condition that, in the Investigator?s opinion would jeopardize the safety of the patient or compliance with the protocol. Medication history 10. Receiving PEG-IFN-alpha-2a within 5 weeks of Screening or having a prior history of 32P therapy. 11. Being treated concurrently with a potent systemic inhibitor of CYP3A4 at the time of Screening (ketoconazole, clarithromycin, itraconazole, nefazodone or telithromycin,. 12. Being treated concurrently with any prohibited medications 13. Previously received treatment with a JAK inhibitor. 14. Being treated concurrently with any investigational agent or prior participation in an investigational study within 30 days prior to the first dose of study drug or within 5-halflives of the investigational product, whichever is longer. Ability to comply with protocol 15. Patients who are unable to comprehend or unwilling to sign an informed consent form (ICF) 16. Patients with active alcohol or drug addiction that would interfere with their ability to comply with the study requirements. Pregnancy and birth control 17. Sexually active males must use a condom during intercourse while taking the drug and for five half-lives after stopping treatment and should not father a child in this period. 18.
