The Benefit/Risk Profile of Pegylated Proline-Interferon Alpha-2b (AOP2014) Added to the Best Available Strategy Based on Phlebotomies in Low-risk Patients With Polycythemia Vera (PV). The Low-PV Randomized Trial
In Brief
A Phase 2 clinical trial evaluating AOP2014, Phlebotomies, and 1 other intervention for Polycythemia Vera. Completed, enrolled 127 participants across 23 sites.
Detailed Summary
The Low-PV study is a multicenter, phase II, randomized trial aimed to assess whether the addition of Pegylated Proline-interferon-alpha-2b to the best therapeutic current strategy available based on phlebotomies and low dose acetylsalicylic acid (ASA) could improve the efficacy of treatment of patients with PV at low risk of thrombosis (younger than 60 years and without prior vascular events), in term of control of recommended level of hematocrit \< 45%, over a period of 12 months.

Timeline
Interventions
AOP2014 will be supplied to the patients as pre-filled auto-injection pens, containing 250 µg of active drug (0.5 ml solution for injection). One pen may be used twice within a time period of 4 weeks. Hence investigators will provide one prefilled pen at every monthly visit. AOP2014 will be self-injected subcutaneously by patients once every 14 days at the single doses of 100 µg (0.2 ml).
According to current common clinical practice the regimen must be selected accordingly to maintain the recommended level of HCT\< 45%. Once normalization of the hematocrit has been achieved, blood counts at regular intervals (every 4 weeks) will establish the frequency of future phlebotomies. Sufficient blood should be removed to maintain the hematocrit below 45%.
100 mg/daily of ASA is recommended (when there are not contraindications) according with current guidelines for this risk class of patients
