A Phase 3 interventional study of Crenolanib and Cytarabine in Relapsed/Refractory Acute Myeloid Leukemia With FLT3 Activating Mutations, sponsored by Arog Pharmaceuticals, Inc.. Completed at 62 sites in 6 countries. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2026-04-09.
Sponsored by Arog Pharmaceuticals, Inc. · Phase 3, Interventional, and Treatment
This is a randomized, multi-center, double-blind, placebo-controlled study designed to evaluate the efficacy of crenolanib administered following salvage chemotherapy, consolidation chemotherapy, post bone marrow transplantation and as maintenance in relapsed/refractory AML subjects with FLT3 activating mutation.
Arog Pharmaceuticals, Inc. is the lead sponsor of 17 studies on the registry; 1 is open to participants now.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.
“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
