Brief Summary

Polycythemia Vera (PV) is a disease of bone marrow stem cells that manifests in a drastic increase of red blood cells and frequently also of white blood cells. The "thickening" of the blood in relation with a modified function of the cells has several consequences like increased blood pressure, pruritus of the skin, fatigue, disturbed blood circulation in the brain as well as fingers and toes and an increased risk of arterial and venous thrombosis (thrombosis is the formation of a blood clot in a vessel); like stroke, cardiac infarction, deep vein thrombosis in the legs. In case of a strong increase of platelets there is an additional risk of bleedings. As the disease progresses the size of spleen and liver increased in most cases and the bone marrow shows signs of fibrosis. In some cases of PV a progression at a later time point to a leukemia (increased formation of white blood cells) can occur. The aim of this study is to show that the study drug AOP2014 (pegylated proline interferon alpha-2b) has the long term efficacy and safety in controlling the disease. A comparison arm is receiving best available therapy as selected by the investigator. Response to the treatment is measured by several blood parameters as well as size of the spleen. Interferon-alpha has been shown to be effective in controlling the blood parameters by immunologically influencing the blood building cells. This can lead to a suppression of the disease-causing stem cells and help healthy stem cells to proliferate. Through this mechanism it is possible that Interferon-alpha can avoid long-term damaging effects of the disease.

Outcome Measures

Primary Outcomes (1)

  • Disease response at quarterly assessment visits

    The primary efficacy endpoint will be the rate of disease response at assessment visits (every 3 months). The co-primary efficacy evaluation criterion will be (1) disease response defined as hematologic response: Hct\<45% without phlebotomy (at least 3 months since the last phlebotomy), PLTs\<400 x 109/L, WBCs\<10 x 109/L, and normal spleen size, and (2) disease response defined as hematologic response (Hct\<45% without phlebotomy (at least 3 months since the last phlebotomy), PLTs\<400 x 109/L, WBCs\<10 x 109/L), resolution and/or clinically improvement of disease-related signs (clinical significant splenomegaly) and disease-related symptoms (microvascular disturbances, pruritus, headache).

Study Arms (2)

Best available therapy (BAT)

ACTIVE COMPARATOR

Best available therapy, as chosen by the investigator for patients who had been on HU in the 1 Year PROUD-PV study

Drug: Best available therapy (BAT)

Pegylated-Proline-interferon alpha-2b

EXPERIMENTAL

AOP2014 for those patients who had been on AOP2014 in the PROUD-PV study

Drug: Pegylated-Proline-interferon alpha-2b

Interventions

Subjects will continue to receive the dosage which delivers the optimal disease response (hematocrit \[Hct\]\<45%, platelets \[PLTs\]\<400 x 109/L and leukocytes \[WBCs\]\<10 x 109/L), as determined in the PROUD-PV study, preferably at the level of target blood values.

Also known as: AOP2014

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients who completed the 12 months AOP2014 treatment arm of the PROUD-PV study and at the "end-of-treatment visit" (EoT) of the PROUD-PV study who fulfill at least one of the following criteria:
  • normalization of at least two out of three main blood parameters (Hct, PLTs and WBCs) if these parameters were moderately increased (Hct\<50%, WBC\<20 x 109/L, PLTs\<600 x 109/L) at baseline of the PROUD-PV study, OR
  • \>35% decrease of at least two out of three main blood parameters (Hct, PLTs and WBCs) if these parameters were massively increased (Hct\>50%, WBCs\>20 x 109/L, PLTs\>600 x 109/L), at baseline of the PROUD-PV study, OR
  • normalization of spleen size, if spleen was enlarged at baseline of the PROUD-PV study, OR
  • otherwise a clear, medically verified benefit from treatment with AOP2014 (e.g. normalization of disease-related micro-vasculatory symptoms, substantial decrease of JAK2 allelic burden).
  • Signed written ICF.

You may not qualify if:

  • Withdrawal criteria, as specified in the PROUD-PV study, which mandate treatment discontinuation:
  • Non-recovery from the AOP2014 related toxicities to the grade (usually, Grade I) which allows continuation of the treatment.
  • HADS score of 11 or higher on either or both of the subscales, and /or development or worsening of the clinically significant depression or suicidal thoughts.
  • Progressive and clinically significant increase of liver enzyme levels despite dose reduction, or if such increase is accompanied by increased bilirubin level, any signs or symptoms of a clinically significant autoimmune disease.
  • Clinically significant development of a new ophthalmologic disorder, or worsening of a pre-existing one, during the study.
  • Loss of efficacy of AOP2014 or any comparable situation where no further benefits of treatment continuation are expected by the investigator.
  • The main efficacy evaluation criterion will be disease response defined as Hct\<45% without phlebotomy (at least 3 months since the last phlebotomy), PLTs\<400 x 109/L, WBCs\<10 x 109/L, and normal spleen size.
  • The main efficacy endpoint will be the maintenance rate of disease response at assessment visits (every three months).
