Further study details as provided by Shire:

Primary Outcome Measures:
  • Number of Patients With Platelet Count ≤600x10^9/L After 12 Months [ Time Frame: 1 year ]
    A platelet count of ≤600x10^9/L after 12 months is considered at least a partial response.

Secondary Outcome Measures:
  • Number of Patients With Platelet Count ≤400x10^9/L After 12 Months [ Time Frame: 1 year ]
    A platelet count of ≤400x10^9/L after 12 months is considered a complete response.

  • Platelet Count [ Time Frame: 1 year ]
  • Red Blood Cell (RBC) Count [ Time Frame: 1 year ]
  • White Blood Cell (WBC) Count [ Time Frame: 1 year ]
  • Differential WBC Count [ Time Frame: 1 year ]
  • Hemoglobin Concentration [ Time Frame: 1 year ]
  • Hematocrit Level [ Time Frame: 1 year ]

Enrollment: 47
Study Start Date: July 2011
Study Completion Date: October 2013
Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions

Study Population
ET patients in Italy

Inclusion Criteria:

  1. Patients must be able to understand and willing to participate in the study, and provide a personally dated and signed written informed consent form.
  2. Patients must have a confirmed diagnosis of ET according to the World health Organisation's criteria.
  3. ET patients who are uncontrolled, in the Investigator's opinion, by first-line (or previous) cytoreductive treatment for efficacy or tolerance reasons.
  4. Patients who have either commenced treatment with anagrelide hydrochloride in the last 7 days or for whom a decision has been documented to commence treatment with anagrelide hydrochloride

Exclusion Criteria:

  1. Patients for whom treatment with anagrelide hydrochloride is contraindicated, according to the current XAGRID SmPC.
  2. Known or suspected intolerance or hypersensitivity to the product, closely related compounds, or any of the stated ingredients.
  3. Patients participating in an interventional research study.
  4. Patients on combination therapy or for whom there is an intention to treat with other cytoreductive agents e.g., hydroxyurea, interferon. Patients can however use aspirin and other anti-aggregatory products at the Investigator's discretion.
