What the trial was testing
The DEEP-2 enrolled 435 patients with beta-thalassemia. The study was sponsored by Consorzio per Valutazioni Biologiche e Farmacologiche and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was a large trial designed to confirm whether the treatment works well enough for wider use. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
Equal performance — 55% vs. 55% iron control success at one year.
The Lancet Haematology · 2020 · NCT01825512
These findings — that iron control success on deferiprone vs. deferasirox in pediatric thalassemia — were published in the The Lancet Haematology and represent the headline result of the study.
Researchers tracked outcomes across 435 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with beta-thalassemia, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Both deferiprone (Ferriprox) and deferasirox (Exjade, Jadenu) are FDA-approved for iron overload from chronic transfusions and available now. Deferiprone requires blood count monitoring for a rare but serious low-white-cell side effect. Ask a hematologist which oral chelator fits your child.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

FLOWER: Following Longitudinal Outcomes With Epidemiology for Rare Diseases
FLOWER is a completely virtual, nationwide, real-world observational study to collect, annotate, standardize, and report clinical data for rare diseases. Patients participate in the study by electronic consent (eConsent) and sign a medical records release to permit data collection. Medical records are accessed from institutions directly via eFax or paper fax, online from patient electronic medical record (EMR) portals, direct from DNA/RNA sequencing and molecular profiling vendors, and via electronic health information exchanges. Patients and their treating physicians may also optionally provide medical records. Medical records are received in or converted to electronic/digitized formats (CCDA, FHIR, PDF), sorted by medical record type (clinic visit, in-patient hospital, out-patient clinic, infusion and out-patient pharmacies, etc.) and made machine-readable to support data annotation, full text searches, and natural language processing (NLP) algorithms to further facilitate feature identification.
