- NCT02128282

- Senhwa Biosciences, Inc.
- 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.

-
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

- Primary Outcome Measures
Name Time Method Maximum Tolerated Dose (MTD) of CX-4945 when used in combination with gemcitabine plus cisplatin. (Phase 1) Cycle 1, 1 Full cycle up to twenty-one (21) days The Maximum Tolerated Dose of CX-4945 will be determined from safety observations during the first cycle, as the CX-4945 dose is escalated in cohorts of three patients in combination with standard gemcitabine plus cisplatin.
Comparison of the Progression-free survival (PFS) between the test and the control arms using Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1 (Phase 2) From date of randomization to date of progression or death from any cause up to 52 weeks. Tumor measurements will be compared to baseline every six weeks, and the PFS will be determined using RECIST v. 1.1.
Recommended Phase II dose (RP2D) and schedule of CX-4945 in combination with gemcitabine plus cisplatin (Phase I) Cycle 1, 1 Full cycle up to twenty-one (21) days The recommended Phase II dose and schedule of CX-4945 will be determined from safety observations during the first cycle, as the CX-4945 dose is administered 1000mg BID in 10-day continuous or 21-day continuous cohorts in combination with standard gemcitabine plus cisplatin.
- Secondary Outcome Measures
Name Time Method Comparison of the Overall Response Rate (ORR) between the test and the control arms using Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1 From date of randomization to date of progression or death from any cause up to 52 weeks. Tumor measurements will be compared to baseline, and the ORR will be determined using RECIST v. 1.1
Comparison of the number of patient who transition to surgical resection From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 60 months The number of patients in the chemotherapy arm versus CX-4945 plus chemotherapy arm who transition to surgical resection will be compared.
Comparison of the Overall Survival (OS) between the test and the control arms From date of randomization to date of death from any cause up to 52 weeks. Time to event is observed during treatment and followed up every 3 months after patient withdraw from treatment.
