Documented resistance/intolerance to prior HU for ET, referencing modified ELN criteria (Barosi, et al, 2007), whereby at least one of the following criteria is met: Platelet count >600 x 10^9/L at ≥2 g/day (or ≥2.5 g/day if subject body weight >80 kg) or maximally tolerated dose if <2 g/day after at least 3 months of HU, or Platelet count >400 x 10^9/L and WBC count <2.5 x 10^9/L at any dose and any duration of HU, or Platelet count >400 x 10^9/L and hemoglobin (HGB) <10 g/dL at any dose and any duration of HU, or Presence of HU-related toxicities at any dose and any duration of therapy (e.g., leg ulcers, mucocutaneous manifestations, pneumonitis, or HU-related fever), or Platelet count >450 x 10^9/L at any dose and any duration of HU.

SURPASS ET Trial Summary

This trial is testing a new drug, P1101, to see if it is more effective and has fewer side effects than the current standard drug, ANA, for treating people with essential thrombocythemia who have not responded well to hydroxyurea.

Who is the study for?
Adults with high-risk Essential Thrombocythemia who have not responded well to Hydroxyurea treatment. They must be Interferon-naïve or negative for anti-P1101 antibodies, meet specific blood count criteria, and have proper liver and kidney function. Participants need to agree to birth control measures and cannot be pregnant or breastfeeding.Check my eligibility
What is being tested?
The trial is testing Ropeginterferon Alfa-2b against Anagrelide in patients resistant or intolerant to Hydroxyurea as a second-line therapy for Essential Thrombocythemia. It's an open-label study where participants are randomly assigned one of the two drugs for comparison over 12 months.See study design
What are the potential side effects?
Possible side effects include reactions related to the immune system, such as flu-like symptoms from interferons, and cardiovascular issues like heart palpitations from Anagrelide. Each drug may also cause general discomforts like headaches, fatigue, nausea, or dizziness.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

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."

Answered by AI

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."

Answered by AI

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."

Answered by AI

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."

Answered by AI

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."

Answered by AI

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."

Answered by AI

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."
