Details and patient eligibility

About

Regorafenib is an oral medication that can interfere with cancer cell growth and reduce the growth of blood vessels around tumors. This study will help find out if regorafenib is a useful drug for treating patients with adenoid cystic carcinomas. Regorafenib has been approved by the Food and Drug Administration (FDA) for use in other cancers, but remains an experimental drug that has not yet been approved for use in adenoid cystic carcinoma.

In this study, the patient will initially be treated with a dose of regorafenib that is lower than what the FDA approved for other cancers in an attempt to decrease the risk of side effects. It is possible that this lower starting dose may not be as effective as the higher FDA approved dose. If the patient does well with the lower dose for at least a month on treatment, the physician may consider increasing the dose to the FDA approved dose.

Inclusion criteria

Patients must have pathologically or cytologically confirmed adenoid cystic carcinoma. Cancers arising from non-salivary gland primary sites are allowed.
Patients must have recurrent and/or metastatic disease not amenable to potentially curative surgery or radiotherapy.
At least 2 weeks must have elapsed since the end of prior systemic treatment (4 weeks for bevacizumab- containing regimens) or radiotherapy with resolution of all treatment-related toxicity to NCI CTCAE Version 4.0 grade ≤1 (or tolerable grade 2) or back to baseline (except for alopecia, lymphopenia, or hypothyroidism). Any number of prior therapies for recurrent/metastatic ACC are allowed.
Patients must have RECIST v1.1 measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for nonnodal lesions and short axis for nodal lesions) as ≥ 20 mm with conventional techniques or as ≥ 10 mm with spiral CT scan.
Patients must have documentation of a new or progressive lesion on a radiologic imaging study performed within 6 months prior to study enrollment (progression of disease over any interval is allowed) and/or new/worsening disease related symptoms within 6 months prior to study enrollment. Note: This assessment will be performed by the treating investigator. Evidence of progression by RECIST criteria is not required.
Patients must have archival tissue from the primary tumor or metastases available for correlative studies. Either a paraffin block or twenty unstained slides are acceptable. If twenty slides are not available, a lesser amount may be acceptable after discussion with the Principal Investigator, Dr. Alan L. Ho.
Patients must agree to undergo biopsy of a malignant lesion. Biopsies do not need to be done if either the investigator or person performing the biopsy judges that no tumor is accessible for biopsy or that biopsy poses too great of a risk to the patient. Patients may also be exempt if frozen tumor tissue has been collected within 12 months of study enrollment that the Principal Investigator deems is appropriate/sufficient for analysis on this protocol.
Age ≥ 18 years.
ECOG performance status ≤ 2 (Karnofsky ≥ 60%,).
Life expectancy of at least 12 weeks (3 months) as determined by the investigator.
Life expectancy of at least 12 weeks (3 months) as determined by the investigator.
Subjects must be able to understand and be willing to sign the written informed consent form. A signed informed consent form must be appropriately obtained prior to the conduct of any trial-specific procedure.
Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements:
- Total bilirubin ≤ 1.5 x the upper limits of normal (ULN) Alanine aminotransferase (ALT) and aspartate amino-transferase (AST) ≤ 2.5 x ULN (≤ 5 x ULN for subjects with liver involvement of their cancer)
- Alkaline phosphatase limit ≤ 2.5 x ULN (≤ 5 x ULN for subjects with liver involvement of their cancer)
- Lipase ≤ 1.5 x the ULN
- Amylase ≤ 1.5 x the ULN Serum creatinine ≤ 1.5 x the ULN or calculated creatinine clearance >60 ml/min
- Platelet count ≥ 100,000 /mm3, hemoglobin (Hb) ≥ 9 g/dL, absolute neutrophil count (ANC) ≥ 1500/mm3. Blood transfusion to meet the inclusion criteria will not be allowed.
Women of childbearing potential must have a negative serum pregnancy test performed within 2 weeks 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.
Subjects (men and women) of childbearing potential must agree to use adequate contraception beginning at the signing of the consent form until at least 3 months after the last dose of study drug. The definition of adequate contraception will be based on the judgment of the principal investigator or a designated associate.
Subject must be able to swallow and retain oral medication.

Exclusion criteria

Concurrent anti-cancer therapy (chemotherapy, definitive radiation therapy, surgery, immunotherapy, biologic therapy, or tumor embolization) other than study treatment. Concurrent therapy with bisphosphonates or denosumab for bone metastases is allowed.

Palliative radiation to non-target lesions is also allowed.

Prior use of regorafenib.
Uncontrolled hypertension (systolic pressure >140 mm Hg or diastolic pressure > 90 mm Hg [NCI-CTCAE v4.0] on repeated measurement) despite optimal medical management.
Concurrent use of another investigational drug or device therapy (i.e., outside of study treatment) during, or within 4 weeks of trial entry (signing of the informed consent form).
Concurrent use of strong CYP3A4 inhibitors (e.g. clarithromycin, grapefruit juice, itraconazole, ketoconazole, nefazodone, posaconazole, telithromycin, and voriconazole). or strong CYP3A4 inducers (e.g. rifampin, phenytoin, carbamazepine, phenobarbital, and St. John's Wort).
Use of any herbal remedy (e.g. St. John's wort [Hypericum perforatum])
Major surgical procedure, open biopsy, or significant traumatic injury within 28 days before start of study medication.
Active or clinically significant cardiac disease including:

Congestive heart failure - New York Heart Association (NYHA) > Class II.

Active coronary artery disease that is not medically treated.
Cardiac arrhythmias requiring anti-arrhythmic therapy other than beta blockers or digoxin.
Unstable angina (anginal symptoms at rest), new-onset angina within 3 months before randomization, or myocardial infarction within 6 months before randomization.
- Therapeutic anticoagulation with Vitamin-K antagonists (e.g., warfarin) is not allowed if the medication dose and/or INR/PTT are not considered stable by the treating physician. If the dose and/or INR/PTT are stable, therapeutic anticoagulation with Vitamin-K antagonists is allowed with close monitoring. Anticoagulation with heparin or heparinoids is allowed.
- Evidence or history of bleeding diathesis or coagulopathy.
- Any hemorrhage or bleeding event ≥ NCI CTCAE Grade 3 within 4 weeks prior to start of study medication.
- Subjects with thrombotic, embolic, venous, or arterial events, such as cerebrovascular accident (including transient ischemic attacks) deep vein thrombosis or pulmonary embolism within 6 months of start of study treatment.
- Subjects with a past or current diagnosis of another malignancy that will interfere with conduct of the trial. Patients with past or current cancer diagnoses other than ACC are allowed to enroll if the investigator believes it will not interfere with trial conduct.
- Patients with phaeochromocytoma.
- Known history of human immunodeficiency virus (HIV) infection or current chronic or active hepatitis B or C infection requiring treatment with antiviral therapy.
- Active infection that would impair the ability of the patient to receive study treatment.

- Any condition which, in the investigator's opinion, makes the subject unsuitable for trial participation.
- Substance abuse, medical, psychological or social conditions that may interfere with the subject's participation in the study or evaluation of the study results.
