- Previously untreated or concurrent cancer that is distinct in primary site or histology except cervical cancer in-situ, treated ductal carcinoma in situ of the breast, curatively treated non-melanoma skin carcinoma, noninvasive aerodigestive neoplasms or superficial bladder tumor; subjects surviving a cancer that was curatively treated and without evidence of disease for more than 3 years before registration are allowed; all cancer treatments for concurrent cancers must be completed at least 3 years prior to registration
- Known history of human immunodeficiency virus (HIV) infection or current chronic or active hepatitis B or C infection requiring treatment with antiviral therapy
- Presence of a non-healing wound, non-healing ulcer or bone fracture
- Major surgical procedure or significant traumatic injury within 28 days before start of study medication
- Renal failure requiring hemo-or peritoneal dialysis
- Seizure disorder requiring medication
- Persistent proteinuria >= grade 3 NCI-CTCAE version (v) 4.0 (> 3.5 g/24 hours [hrs], measured by urine protein: creatinine ratio on a random urine sample)
- Interstitial lung disease with ongoing signs and symptoms at the time of informed consent
- Pleural effusion or ascites that causes respiratory compromise (>= NCI-CTCAE version 4.0 grade 2 dyspnea)
- History of organ allograft (including corneal transplant) except stem cell transplants
- Known or suspected allergy or hypersensitivity to any of the study drugs, study drug classes, or excipients of the formulations given during the course of this trial
- Any malabsorption condition
- Women who are pregnant or breast-feeding, or intend to become pregnant during the study; women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of study drug; post-menopausal women (defined as no menses for at least 1 year) and surgically sterilized women are not required to undergo a pregnancy test
- Substance abuse, medical, psychological or social conditions that may interfere with the subject’s participation in the study or evaluation of the study results
- Presence of unresolved toxicities from prior anticancer therapy, defined as having not resolved to NCI CTCAE v4.03 grade 0 or 1 with the exception of alopecia; subjects with irreversible toxicity that is not reasonably expected to be exacerbated by regorafenib (e.g. hearing loss, neuropathy) may be included after consultation with the principal investigator
- Uncontrolled inter-current illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, uncontrolled cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
I. To assess safety and tolerability of regorafenib in patients with advanced myeloid malignancies.
II. To define a maximum tolerated dose (MTD) of regorafenib and to characterize its dose-limiting toxicities (DLTs) in patients with advanced myeloid malignancies.
I. To assess the pharmacodynamics of regorafenib via changes in known regorafenib targets such as vascular endothelial growth factor (VEGF), soluble VEGFR1, basic fibroblast growth factor (bFGF), VEGF-C, VEGF-D, sVEGFR2, placental-derived growth factor (P1GF), soluble TIE-2, soluble (s)- c-KIT, stromal-derived factor 1 alpha (SDF1 alpha), as well as inflammatory biomarkers and markers of tumor hypoxia and correlate changes in these with treatment response.
II. To assess treatment response, progression-free and overall survival in patients with acute myeloid leukemia (AML) who receive regorafenib.
III. To measure changes in specific markers of allele burden, when applicable (such as JAK2 V617F allele burden, FLT3-ITD, RAS, IDH and specific mutations found in each patient sample) and correlate them with treatment response.
OUTLINE: This is a dose-escalation study.
Patients receive regorafenib orally (PO) once daily (QD) on days 1-21. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 12 months.
