Study Summary

This trial is testing a new drug, AG-348, for adults with non-transfusion-dependent thalassemia, a genetic blood disorder. The trial includes a core period of 24 weeks followed by an extension period of up to 10 years for eligible participants.

Who is the study for?
Adults with non-transfusion-dependent thalassemia (NTDT) who haven't had more than 5 blood transfusions in the last 24 weeks and none in the past 8 weeks. Participants must have a documented history of thalassemia, adequate organ function, and agree to use two forms of contraception if applicable. Exclusions include prior treatments like gene therapy or certain drugs, recent major surgery, or serious allergies.Check my eligibility
What is being tested?
The trial is testing AG-348's effectiveness for NTDT over up to 10 years. Starting with a dose of 50 mg twice daily, which may increase to 100 mg based on safety and hemoglobin levels after six weeks. The study aims to understand how well AG-348 works and its effects on the body.See study design
What are the potential side effects?
While specific side effects are not listed here, common ones associated with new medications can include digestive issues, headaches, fatigue, potential allergic reactions or skin rashes. Organ function will be monitored due to possible impacts from long-term medication use.

Experimental Treatment
Group I: AG-348Experimental Treatment1 Intervention
Participants with alpha or beta thalassemia received AG-348 50 mg twice daily (BID), orally up to Week 6. Following Week 6, depending on the participants' safety and hemoglobin (Hb) concentrations, they could undergo one potential dose-level increase from 50 to 100 mg BID. After completion of the Core Period of 24 weeks, participants were eligible to continue to receive AG-348 in the Extension Period which is up to 10 years.

Frequently Asked Questions

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

Are we still enrolling individuals for this research project?

"This study has completed patient recruitment and is no longer enrolling new participants. If you are interested in other clinical trials, there are 61 thalassemia studies and 9 AG-348 trials that are still looking for patients."

Answered by AI

How many people total will be in this experiment?

"This study has completed recruitment for participants. The trial was first posted on December 28th, 2018 and was last edited on July 21st, 2022. For individuals interested in other studies, 61 trials for thalassemia and 9 trials AG-348 are currently open."

Answered by AI

What is the uniqueness of this clinical trial?

"AG-348 has had a long journey from its first clinical trial in 2015 to the present day, where there are 9 different ongoing trials involving the drug. The original study was conducted by Agios Pharmaceuticals, Inc. and 52 patients were enrolled. AG-348 received Phase 2 approval after this initial success. Now, the medication is being tested in 61 cities across 28 countries."

Answered by AI

What other tests has AG-348 undergone in the past?

"AG-348 was first pioneered in 2015 by researchers at Stanford University. So far, there have been 12 completed clinical trials with 9 more active ones. A considerable amount of these ongoing studies are based in Toronto, Canada."

Answered by AI

Has AG-348 undergone the FDA's regulatory process?

"While there is some evidence to support AG-348's safety, as this drug is still in Phase 2 of testing, the lack of data with regards to efficacy rates warrants a score of 2."
