NCT01949805

  Purpose

Phase III study to compare the efficacy and safety of the novel monopegylated interferon alpha 2b AOP2014 versus Hydroxyurea (the current licensed therapy for this disease). One year treatment of patients with polycythemia vera. The hypothesis is that AOP2014 is superior to HU to achieve response rates measured after one year. Response is measured as normalisation of key lab parameters as well as normalized spleen size.

Primary Outcome Measures:
  • Disease response rate [ Time Frame: Month 12 ] [ Designated as safety issue: No ]
    Disease response rate is defined as hematocrit <45% without phlebotomy (at least 3 months since last phlebotomy), platelets <400 G/L, leukocytes <10 G/L , and normal spleen size


Secondary Outcome Measures:
  • Disaese response [ Time Frame: at month 3, 6 and 9 ] [ Designated as safety issue: No ]
  • JAK2 allelic burden changes [ Time Frame: at month 6 and 12 ] [ Designated as safety issue: No ]
  • time to response [ Time Frame: from inclusion until first response confirmation ] [ Designated as safety issue: No ]
    will be measured during the study period of 12 months

  • duration of response [ Time Frame: during the 12 months of study duration ] [ Designated as safety issue: No ]
    from the first documented response on study

  • number of phlebotomies [ Time Frame: from inclusion until month 12 ] [ Designated as safety issue: No ]
  • blood parameters [ Time Frame: from inclusion until month 12 ] [ Designated as safety issue: No ]
    biweekly

  • spleen size [ Time Frame: at month 3, 6, 9 and 12 ] [ Designated as safety issue: No ]
    both centrally (blinded assessment) and locally

  • disease related symptoms [ Time Frame: from inclusion until month 12 ] [ Designated as safety issue: No ]
    biweekly

  • adverse events [ Time Frame: from inclusion until month 12 ] [ Designated as safety issue: Yes ]
    biweekly

  • protocol-specific adverse events of special interest [ Time Frame: from inclusion until month 12 ] [ Designated as safety issue: Yes ]
    biweekly

Criteria

Inclusion Criteria:

  3. For previously cytoreduction untreated patients - documented need of cytoreductive treatment

    - leukocytosis (WBC>10G/L for two measurements within one week)

  4. For patients currently treated or pre-treated with HU, all of the following criteria:

    • being non responders (as defined by the response criteria for primary endpoint)
    • total HU treatment duration shorter than three years
    • no documented resistance or intolerance as defined by modified Barosi et al, 2009 criteria
  5. Hospital Anxiety and Depression Scale (HADS) score 0-7 on both subscales
  6. Patients with HADS score of 8-10 inclusive on either or both of the subscales may be eligible following psychiatric assessment that excludes clinical significance of the observed symptoms in the context of potential treatment with an interferon alpha
  7. Signed written informed consent

Exclusion Criteria:
