What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ItacitinibDrug
Also called INCB039110
Itacitinib at the protocol-defined dose administered orally once daily (QD) plus corticosteroids.
PlaceboDrug
Matching placebo tablets administered orally once daily (QD) plus corticosteroids.
PrednisoneDrug
Also called Deltasone, Prednicot, predniSONE Intensol, Rayos
Oral prednisone may be used to begin standard corticosteroid background treatment at the investigator's discretion, at a dose equivalent to methylprednisolone 2 mg/kg per day.
Also called Medrol, Medrol Dosepak, Solu-Medrol
Methylprednisolone 2 mg/kg IV daily (or prednisone equivalent) or at a dose appropriate for the severity of disease as background treatment.

Defined as the interval from study enrollment to death due to any cause.
Measured: End of Study up to approximately 24 months
Number of Treatment-emergent Adverse Events With INCB39110
Adverse events reported for the first time or worsening of a pre-existing event after the first dose of study treatment
Measured: 30-35 days after end of treatment, approximately 24 months
Incidence Rate of Secondary Graft Failure
Defined as > 95% recipient cells any time after engraftment with no signs of relapse, OR retransplantation because of secondary neutropenia (< 0.5 × 109/L) and/or thrombocytopenia (< 20 × 109/L) within 2 months of transplantion
Measured: Randomization through end of Study, study duration expected to average 24 months
Proportion of Subjects Who Discontinue Corticosteroids
Average and cumulative corticosteroid dose usage will be calculated and proportion of subjects discontinuing corticosteroids will be tabulated
Measured: Days 28, 56, 100, and 180

Summary statistics of subjects discontinuing immunosuppressive medications will be calculated
Measured: Days 56 and 100

Measured: up to day 100
Incidence Rate of cGVHD
Measured: Days 180 and 365
Objective Response Rate
Measured: Days 14, 56 and 100

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Itacitinib, Prednisone and Methylprednisolone in people with Graft-versus-host Disease (GVHD), run by Incyte Corporation at 129 sites in 19 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 129 sites in United States, Italy, Spain, Belgium, France and 14 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 15 May 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall Response Rate Based on Center for International Blood and Marrow Transplant Research (CIBMTR) Response Index (time frame: Day 28). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03139604, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2025.
