Frequently Asked Questions
What is the regulatory agency's stance on Ropeginterferon alfa-2b?
"There is some efficacy data and multiple rounds of safety data available from Phase 3 trials, so Ropeginterferon alfa-2b was given a score of 3 for safety."
What goals does this research hope to realize?
"The primary goal of this study, to be evaluated at 9 and 12 months, is large symptom improvement or maintaining lack of progression. Additionally, researchers will track changes in CALR, MPL, and JAK-2 allelic burden over time (termed the "response rate"), as well as the longitudinal rate of change in ELN response rates over the course of the year-long study."
What other scientific papers exist that mention Ropeginterferon alfa-2b?
"Ropeginterferon alfa-2b was first studied in 2015 at the Mayo Clinic in Arizona. As of now, there have been 20 completed trials and 7 active studies. A notable number of these latter investigations are being conducted in Vancouver, British Columbia."
How many participants are accepted into this research project?
"In order to carry out this research, 160 patients that meet the required criteria must be recruited. The sponsor company, Medpace Inc., will delegate the trial between multiple locations like St. Paul's Hospital in Vancouver and Mayo Clinic in Phoenix."
What are the typical conditions that Ropeginterferon alfa-2b is used to treat?
"The conditions of polycythemia vera (pv), splenomegaly, and thrombocythemia can all be treated by Ropeginterferon alfa-2b."
In how many different geographical locations is this study being conducted?
"Right now, medical professionals are looking for patients to fill 14 different sites across North America. If you enroll in this trial, it would be convenient to choose a location near you to reduce travel time and costs."
Can patients still enroll in this research project?
"The online clinical trials database does show that this study is still taking in patients. This trial began recruitment on August 25th, 2020 and the listing was updated December 30th, 2021. There are 160 total participants needed for this trial, spread out over 14 locations."
