Study Summary

This trial is testing the long-term tolerability and safety of mitapivat (or AG-348) in people with sickle cell disease.

Who is the study for?
Adults aged 18-70 with Sickle Cell Disease (SCD) who previously participated in NIH study #19H0097 and benefited from it. They must have stable organ function, no recent blood transfusions, and for women of childbearing potential, a commitment to use two forms of contraception. Exclusions include significant heart rhythm issues, uncontrolled medical conditions like hypertension or diabetes, active infections or certain drug allergies.Check my eligibility
What is being tested?
The trial is testing the long-term safety and effectiveness of mitapivat tablets taken twice daily by people with SCD. It extends a previous study to see if benefits continue or improve over time. Participants will undergo various health assessments including physical exams, blood tests, heart checks (ECG), mobility tests (6-minute walk), echocardiograms for heart/lung function, bone scans (DXA), and health questionnaires.See study design
What are the potential side effects?
While specific side effects are not listed here, participants will monitor any symptoms they experience in a study diary which may include typical drug-related reactions such as digestive discomforts, potential liver enzyme changes due to medication metabolism challenges or other common medication-induced complications.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
measure: Long-term safety and tolerability of mitapivat in subjects with stable sickle cell disease
Secondary outcome measures
To evaluate hemoglobin (Hb) response, changes in hemolytic markers, functional status, cardiopulmonary function, and health-related quality of life in SCD subjects maintained on mitapivat long-term.
To evaluate the pharmacokinetic
To monitor SCD-related safety endpoints in SCD subjects maintained on mitapivat long-term.

Trial Design

1Treatment groups
Experimental Treatment
Group I: 1Experimental Treatment1 Intervention
Subjects will be treated with a maintenance dose of mitapivat previously assessed for safety and tolerability in the Phase I study for an initial 48 weeks and undergo safety monitoring, evaluation of pharmacokinetics and pharmacodynamics, and assessment of secondary laboratory and clinical endpoints at pre-specified intervals during the study period.

How can I become a participant in this experiment?

"This clinical trial is looking for 15 patients with hemolytic anemia that meet the following requirements: between 18-70 years old, have not received a blood transfusion in the last 12 weeks, have Hb A on hemoglobin analysis, have a serum AST <=2.5 x ULN, have a serum ALT <=2.5 x ULN, have a serum creatinine <=1.25 x UNL, and finally have an absolute neutrophil count >=1.0 x 10^9power/L.."

Answered by AI

Are people with the relevant medical condition able to participate in this trial at this time?

"The clinical trial mentioned is not enrolling patients at the moment, based on the latest information available from clinicaltrials.gov. This study was originally posted on December 9th 2020 and was last edited on October 27th 2022. There are 249 other studies that are actively recruiting participants right now."
