E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate and evaluate the activity and safety (in terms of complete haematological response within one year) of Ruxolitinib in the treatment of patients with Polycythaemia Vera (PV) or Essential Thrombocythaemia (ET) who have met criteria for resistance or intolerance of hydroxycarbamide (HC) therapy. |
|
E.2.2 | Secondary objectives of the trial |
• Partial response rates as defined by European LeukemiaNet criteria within 1 year of treatment • Duration of response • To determine the toxicity profile of Ruxolitinib based on CTC criteria • Dose intensity • To assess the histological response: bone marrow biopsy analysis criteria as defined by European LeukemiaNet • To assess the molecular response: JAK2 V617F status quantitation; criteria defined by European LeukemiaNet • To assess the haemorrhagic and thromboembolic event rate • To assess change in quality of life and disease symptom burden • Overall survival • Progression free survival |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Inclusion Criteria for PV • Male or female patient ≥ 18 years of age • A confirmed diagnosis of high risk* PV
*High Risk is defined as ANY ONE of the following: - Age >60 years - Previous documented thrombosis (including Transient Ischaemic Attack (TIA)), erythromelalgia or migraine (severe, recurrent, requiring medications, and felt to be secondary to the MPN) either after diagnosis or within 10 years before diagnosis and considered to be disease related - Significant splenomegaly (i.e. > 5cm below costal margin on palpation) or symptomatic (splenic infarcts or requiring analgesia) - Platelets > 1000 x 10^9/L - Diabetes or hypertension requiring pharmacological therapy for > 6 months

*High risk is defined as ANY ONE of the following: - Age > 60 years - Platelet count > 1500 x 10^9/L - Previous documented thrombosis (including Transient Ischaemic Attack (TIA)), erythromelalgia or migraine (severe, recurrent, requiring medications, and felt to be secondary to the MPN) either after diagnosis or within 10 years before diagnosis and considered to be disease related - Previous haemorrhage related to ET - Diabetes or hypertension requiring pharmacological therapy for > 6 months
ALL patients MUST ALSO be EITHER intolerant OR resistant to Hydroxycarbamide (HC) based on the following established criteria: Any ONE of the following: - Platelet count >600 x 10^9/L after 8 weeks of at least 2 g/day or MTD of HC (2.5 g/day in patients with a body weight>80 kg) - Platelet count >400 x 10^9/L and WBC < 2.5 x 10^9/L at any dose of HC (for a period of at least 8 weeks) - Platelet count >400 x 10^9/L and Hb < 11 g/dl at any dose of HC (for a period of at least 8 weeks) - Platelet count persistently <100 x 109/L at any dose of HC (for a period of at least 8 weeks) - Progressive splenomegaly or hepatomegaly i.e. enlargement by more than 5cm or appearance of new splenomegaly or hepatomegaly on HC treatment - Not achieving the desired reduction of haematocrit or packed cell volume with the addition of HC in patients who do not tolerate frequent venesections after 8 weeks of at least 2 g/day of HC (2.5 g/day in patients with a body weight >80 kg) - Not achieving the desired stable reduction of WBC when leukocytes are a target of therapy after 8 weeks of at least 2 g/day or MTD of HC (2.5 g/day in patients with a body weight>80 kg) - Thrombosis or haemorrhage (including Transient Ischaemic Attack (TIA)) while on therapy - Presence of leg ulcers or other unacceptable HC-related non-haematological toxicities, such as unacceptable mucocutaneous manifestations, gastrointestinal symptoms, pneumonitis or fever at any dose of HC. OR Cycling platelet counts on therapy - Disease related symptoms not controlled by hydroxycarbamide
The patient can have met any one of the above criteria AT ANY POINT in their disease whilst on Hydroxycarbamide. |
