About
Determine the doses and schedule appropriate for phase 2 study of sorafenib and vorinostat with concurrent gemcitabine and radiation therapy (RT) as neoadjuvant treatment of pancreatic cancer following chemotherapy. Recommended phase II dose RP2Ds and schedule of sorafenib and vorinostat defined as the doses and schedule that are the same as or less than the maximum tolerated dose (MTD) and schedule.
Full description
This is a phase 1 study of concurrent chemoradiation using a regimen of sorafenib and vorinostat with gemcitabine and radiation following chemotherapy in patients with pancreatic cancer to find the recommended phase II dose (RP2D) of the concurrent chemoradiation combination. A traditional 3+3 dose-escalation design will be conducted for the sorafenib and vorinostat dose escalation. Adenocarcinoma of the pancreas without distant metastasis that has been treated with ≥ 1 prior therapy (not including radiation) encompassing at least 2 months. Adequate hematologic, hepatic, and renal function. Ability to take oral medication. To determine the doses and schedule appropriate for phase 2 study of sorafenib and vorinostat with concurrent gemcitabine and radiation therapy (RT) as neoadjuvant treatment of pancreatic cancer following chemotherapy.This is a dose-escalation trial employing a standard "3+3" schema of sorafenib and vorinostat.

Inclusion criteria
- Adenocarcinoma of the pancreas
- Prior therapy with ≥ 1 prior systemic therapy over a period of at least 2 months (eg, at least two 4-week cycles of a regimen such as gemcitabine and nab-paclitaxel; or at least four 2-week cycles of a regimen such as FOLFOX, FOLFIRINOX, or FOLFIRI) -Candidate for additional therapy consisting of radiation with gemcitabine- radiosensitization.
- Able to initiate study treatment no later than 9 weeks from last dose of any antineoplastic component of prior therapy regimen.
- Recovery from ≥ grade 2 toxicities of prior therapy regimen to grade 1 or baseline, with the exception of anemia and lymphopenia and chronic residual toxicities that in the opinion of the investigator are not clinically relevant given the known safety/toxicity profiles of gemicitabine, sorafenib, and vorinostat (eg, alopecia, changes in pigmentation, stable endocrinopathies). Patients with ≤ grade 2 peripheral sensory or motor neuropathy are eligible..

- Total bilirubin <= 1.5 x ULN for the laboratory at the time of enrollment, all forms of biliary stents allowed
- Creatinine clearance >= 45 mL/min as calculated by the standard Cockcroft-Gault equation using age, actual weight, creatinine and gender
- International normalized ratio (INR) <= 1.5
- Absolute neutrophil count (ANC) >= 1,500/mm^3
- Platelets >= 100,000/mm^3 (may not be transfused to meet this level for enrollment)
- Measurable or evaluable disease by Response Evaluation Criteria in Solid Tumors (RECIST) (version [v]1.1
- Ability to understand and the willingness to sign a written informed consent document
- Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of treatment
- Women of childbearing potential and men must agree to use a medically accepted form of birth control during the treatment and for 2 months following completion of study treatment
Exclusion criteria
-
Prior radiotherapy for pancreatic cancer
-
Prior surgical resection of pancreatic cancer
-
Evidence of metastatic disease
-
Any investigational agent within 4 weeks of study treatment initiation
-
Diagnosis or treatment for another malignancy within 3 years of enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, any in situ malignancy, or low-risk prostate cancer after curative therapy
-
Intolerance of protocol agents as follows:
- Known or presumed intolerance of gemcitabine, vorinostat or sorafenib
- Experienced any of the following toxicities with prior gemcitabine adminstration (if given): capillary leak syndrome, posterior reversible encephalopathy, hemolytic uremic syndrome, thrombotic thrombocytopenic purpura, unexplained dyspnea or other evidence of severe pulmonary toxicity, or severe hepatic toxicity
-
Unable to swallow medication
-
Suspected malabsorption or obstruction; note: use of pancreatic enzyme supplements is allowed to control malabsorption
-
Contraindication to antiangiogenic agents, including:
- Bronchopulmonary hemorrhage/bleeding event >= grade 2 (Common Terminology Criteria for Adverse Events [CTCAE] v4.0) within 12 weeks prior to of treatment
- Any other hemorrhage/bleeding event >= grade 3 (CTCAE v4.0) within 12 weeks prior to initiation of treatment
- Serious non-healing wound, ulcer, or bone fracture
-
Arterial thrombotic or embolic events such as a myocardial infarction or cerebrovascular accident (including transient ischemic attacks) within the 6 months prior to initiation of treatment. Incidental clinically insignificant embolic phenomena that do not require anti-coagulants are not excluded. Also,tumor-associated thrombus of locally-involved vessels does not count as an exclusion criterion.
-
Clinically significant cardiac disease, including major cardiac dysfunction, such as uncontrolled angina, clinical congestive heart failure with New York Heart Association (NYHA) class III or IV, ventricular arrhythmias requiring anti-arrhythmic therapy, recent (within 6 months) myocardial infarction or unstable coronary artery disease
-
Concomitant use of other histone deacetylase (HDAC) inhibitors
-
Planned ongoing administration of STRONG cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) inducers. Examples of clinical inducers and classifications of strong, moderate, and weak interactions are available through the FDA website (Table 3-3 of website): http://www.fda.gov/Drugs/DevelopmentApprovalProcess/DevelopmentResources/DrugInteractionsLabeling/ucm093664.htm
-
Persistent heart rate (HR) < 50 or > 120 beats per minute (bpm).
-
QT(c) ≥ 481 ms (>= grade 2) on electrocardiogram (ECG) prior to initiation of treatment
-
If baseline QTc on screening ECG meets exclusion criteria:
- Check potassium and magnesium serum levels
- Correct any identified hypokalemia and/or hypomagnesemia and repeat ECG to confirm exclusion of patient due to QTc
-
For patients with HR >60 of >100 beats per minute (bpm), no manual read of QTc is required
-
For patients with baseline HR < 60 or > 100 bpm, manual read of QT by cardiologist is required, with Fridericia correction applied to determine QTc
-
-
Planned ongoing treatment with other drugs thought to potentially adversely interact with study drugs; if such medications have been used, patients must be off of these agents for >= 2 weeks prior to initiation of treatment:
- Anticoagulants at therapeutic doses
- Immunosuppressants such as tacrolimus, leflunomide or tofacitinib, roflumilast, pimecrolimus
-

-
Medical, psychological, or social conditions that, in the opinion of the investigator, may increase the patient's risk or interfere with the patient's participation in the study or hinder evaluation of the study results
