Summary

This trial is testing a drug that could improve the lives of people with beta thalassemia or other hemoglobinopathies by increasing the levels of fetal globin protein.

Who is the study for?
The trial is for adults with Beta thalassemia intermedia or Non-Transfusion Dependent Thalassemia who have a specific mutation, with hemoglobin levels between 6.0 and 10.0 g/dL. Participants must not be on oxygen therapy for pulmonary hypertension, have certain liver conditions, untreated HIV or hepatitis C, recent fever, other recent treatments or transfusions, or be pregnant/breastfeeding.
What is being tested?
An oral drug known as Benserazide Only Product is being tested to increase fetal globin in red blood cells which could benefit those with beta thalassemia and related blood disorders. The study starts by testing three dose levels in nontransfused patients before moving to larger groups.
What are the potential side effects?
While the trial description does not specify side effects of Benserazide Only Product directly since it's considered safe for long-term use from past applications, potential risks may include typical drug reactions such as digestive issues, allergic responses or fatigue.
