The purpose of this study is the identification of the maximum tolerated dose (MTD) of the investigational medicinal product. Moreover the safety and tolerability will be assessed and an exploratory analysis of efficacy and biomarker modulation will be performed.

Condition Intervention Phase
Polycythemia Vera
Drug: PEG-P-INF alpha-2b (P1101)
Phase 1
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: An Open-label, Prospective, Multicentre, Phase I/II Dose Escalation Study to Determine the Maximum Tolerated Dose and to Assess the Safety and Efficacy of P1101, PEG-Proline-Interferon Alpha-2b in Patients With Polycythaemia Vera

Primary Outcome Measures:
  • Maximum tolerated dose (MTD) [ Time Frame: The incidence of dose limiting toxicities (DLTs), which define the MTD are assessed continously until achievement of MTD. ]
    The definition of MTD is based on a 3+3 dose escalation design. MTD is defined as the next lower dose of that dose which was considered to be untolerated (observed DLT frequency at least 2 out of 3 in one cohort or at least 2 out of six patients in 2 cohorts).

Estimated Enrollment: 24
Study Start Date: August 2010
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
