Study Summary

This trial looks at P1101 to treat patients with myelofibrosis. P1101 may help the body's natural response and slow the growth of myelofibrosis.

Who is the study for?
This trial is for patients with myelofibrosis who have symptoms like anemia and enlarged spleen, and are in different stages of the disease. Some should not have had treatment before, while others may have tried a drug called ruxolitinib without success. Participants need to be relatively healthy otherwise, able to answer questions about their health, and willing to provide blood samples.Check my eligibility
What is being tested?
The trial is testing P1101 (PEG-proline-interferon alpha-2b), which might help the body fight myelofibrosis better by slowing its growth. The study includes tests on how this treatment affects patients' quality of life and tracks changes through lab biomarker analysis.See study design
What are the potential side effects?
While specific side effects for PEG-proline-interferon alpha-2b aren't listed here, similar drugs can cause flu-like symptoms, fatigue, mood changes or depression, irritation at injection site, and sometimes changes in blood counts leading to increased risk of infections.

Frequently Asked Questions

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

What research has been undertaken to measure Quality-of-Life?

"Presently, 32 medicinal trials exploring Quality-of-Life Assessment are ongoing with 12 of them in the third phase. Although Buffalo, New york hosts many of these studies, there are 3489 other sites carrying out investigations related to Quality-of-Life Assessment."

Answered by AI

Does Quality-of-Life Assessment pose any risks to participants?

"Quality-of-Life Assessment is ranked a 2 on our scale due to its Phase 2 designation, indicating that some safety data has been gathered but there are no studies yet supporting efficacy."

Answered by AI

How is Quality-of-Life Assessment typically employed?

"Quality-of-Life Assessment is primarily employed to address malignancies and hematologic conditions. Additionally, the procedure has been found successful at ameliorating non-hodgkin's lymphoma, follicular lymphoma, hepatitis c virus (hcv) infection, and amino acid supplementation."

Answered by AI

Is there an opportunity for new participants to join this research endeavor?

"The clinicaltrials.gov webpage suggests that this study, first posted on August 12th 2015 and last updated October 25th 2022, is no longer searching for participants. Nonetheless, there are 125 other trials actively recruiting at the moment."
