Brief Summary

This study considers the safety and tolerability of increasing doses of CX-4945 in combination with gemcitabine plus cisplatin to determine the maximum tolerated dose (MTD) and the recommended Phase II dose (RP2D), followed by a randomized study that compares antitumor activity in cholangiocarcinoma patients receiving the standard of care gemcitabine plus cisplatin versus CX-4945 at the combination RP2D with gemcitabine plus cisplatin.

Detailed Description

Protein kinase CK2 is a constitutively active serine/threonine kinase with a long history as a pro-survival, anti-apoptotic kinase. Given the wide spread overexpression of CK2 in multiple cancers and its role in multiple non-oncogenic processes required to sustain the cancer phenotype, a selective inhibitor of CK2 is an attractive targeted approach to treating cancer.

CX-4945 is a tetracyclic, small molecule carboxylate acid salt that exhibits potent and highly selective inhibition of CK2. Protein kinase CK2 is also known to play an important role in the DNA damage repair mechanisms of cancer cells, and this study of CX-4945 in combination with gemcitabine plus cisplatin will determine if inhibition of CK2, in conjunction with the use of chemotherapy drugs, will result in improved clinical outcomes for patients with non-resectable cholangiocarcinoma.

Eligibility Criteria

Inclusion Criteria

• Presence of an unresectable hepatobiliary mass or metastatic disease (consistent with cholangiocarcinoma, as evidenced by histology or cytology (augmented by fluorescence in situ hybridization (FISH) where appropriate), for which treatment with gemcitabine plus cisplatin is intended. Intrahepatic and extrahepatic cholangiocarcinoma patients may be enrolled.
• For patients enrolled in the Dose Escalation Phase, one or more tumors measurable on radiograph or CT scan, or evaluable disease defined as non-measurable lesions per RECIST v. 1.1 (e.g., malignant ascites). All patients enrolled to the Randomized Study Phase must have measurable disease only.
• Laboratory data as specified below:

• Hematology: Absolute neutrophil count (ANC) >1,500 cells/mm3, platelet count >100,000 cells/ mm.cu. and hemoglobin > 9 g/dL
• Hepatic: bilirubin <1.5 X Upper Limit of Normal (ULN); alkaline phosphatase (ALP), alanine aminotransferase (ALT) or aspartate aminotransferase (AST) < 5.0 X ULN
• Renal: serum creatinine within normal limits (WNL), defined as within 25% of the institution's stated reference range, or a calculated creatinine clearance >45 mL/min/1.73 m. sq. for patients with abnormal, increased, creatinine levels.
• Coagulation: International Normalized Ratio (INR) < 1.5 times normal, activated Partial Thromboplastin Time (aPTT) < 1.5 times normal. Patients receiving therapeutic doses of anticoagulant therapy may be considered eligible for the trial if INR and aPTT are within the acceptable therapeutic limits for the institution.

• Concurrent severe or uncontrolled medical disease (i.e., systemic infection, diabetes, hypertension, coronary artery disease, congestive heart failure).
• Active symptomatic fungal, bacterial and/or viral infection including active HIV or viral (A, B or C) hepatitis which would not permit the patient to be managed according to the protocol.
• Difficulty with swallowing or an active malabsorption syndrome.
