Ropeginterferon Alfa-2b in Patients With Polycythemia Vera (PV) Without Symptomatic Splenomegaly: A Prospective, Longitudinal, Multicenter, Observational Study in Germany
Summary: The primary objective of this non interventional study is to evaluate symptom burden in adult patients with PV without symptomatic splenomegaly during treatment with ropeginterferon alfa-2b in a real-world setting. Further patient-relevant endpoints include effectiveness including complete hematologic response (CHR), event-free survival (EFS), safety and tolerability, treatment reality including d...
A Phase I/IB Study of Ropeginterferon in Patients With Cutaneous T-Cell Lymphoma (CTCL)
Summary: This is a single-center, phase I/IB study to identify the recommended phase II dose of Ropeginterferon-alfa 2b (P1101) in patients with CTCL who have failed at least two prior lines of skin-directed therapy (Stage IA-IB) or have less than a complete response to phototherapy or extracorporeal photopheresis (ECP) or total skin electron beam therapy (TSET), or stable/progressive disease after at leas...
LOW-PV Continuation
Summary: This multicenter longitudinal observational study focuses on Italian patients with Polycythemia Vera (PV) who were enrolled in the Low-PV RCT and continued receiving Ropeginterferon alfa-2b until the study's conclusion on March 31, 2023. It includes patients who were responders to Ropeginterferon alfa-2b after two years in the phase II randomized trial LOW-PV. Data will be collected retrospectivel...
A Randomized, Double-Blind, Placebo-Controlled Multicenter Phase III Study to Assess Efficacy and Safety of Ropeginterferon Alfa-2b (P1101) in Adult Patients With Pre-fibrotic/Early Primary Myelofibrosis (PMF) or Overt PMF at Low or Intermediate-1 Risk According to DIPSS Plus (HOPE-PMF): The Core Study and Its Extension Study
Summary: This is a phase 3 double-blind clinical trial arm to test Ropeginterferon alfa-2b (P1101) in adult patients with Primary Myelofibrosis (PMF) at early stage or low to medium risk. Participants will receive the study drug/placebo bi-weekly and have an assessment visit every 4 weeks. The ratio of study drug to placebo group is 2:1.
Safety and Efficacy of Ropeginterferon Alfa-2b in Combination With Ruxolitinib in Patients With Myelofibrosis Demonstrating Suboptimal Response to Ruxolitinib Monotherapy
Summary: In this open-label single arm phase 2 study, approximately 20 patients with MF demonstrating suboptimal response to ruxolitinib monotherapy will be enrolled. Patients will continue to receive ruxolitinib at a stable dose and ropeginterferon alfa 2b will be added to the regimen.
Extension Study of P1101 in Japanese Patients Who Have Completed Phase 2 Single Arm Study in Polycythemia Vera (PV) Patients (Study A19-201) or Phase 3 Study in Essential Thrombocythemia (ET) Patients (Study P1101 ET)
Summary: This is a Phase 3 open-label, multicenter, single arm study designed to evaluate the efficacy and safety and tolerability of P1101 patient with PV or ET in long-term.
Efficacy and Safety of Ropeginterferon Alfa-2b for Pre-fibrotic Primary Myelofibrosis and DIPSS Low/Intermediate-1 Risk Myelofibrosis
Summary: This is a multi-centre phase 2 open-label prospective study designed to assess the efficacy and safety of ropeg patients with pre-fibrotic primary myelofibrosis or DIPSS low/intermediate-1 risk myelofibrosis after 24 months of treatment.
