OVERVIEW – in layman’s terms (150 words max)
ABC-108 is a clinical study of ABC294640 in the treatment of advanced, unresectable intra-hepatic, perihilar and extra-hepatic cholangiocarcinoma (CCA). In this clinical study, all participants will be receiving ABC294640 orally, twice a day, in 28 day cycles. Participants will be monitored for safety and to determine response to the study drug.

The study drug, ABC294640 is an orally available inhibitor of the enzyme sphingosine kinase-2 (SK2). SK2 is an innovative target for anti-cancer therapy because of its critical role in sphingolipid metabolism, which is known to regulate tumor cell death and proliferation. ABC294640 also inhibits proliferation and induces apoptosis of cholangiocarcinoma cell lines. Furthermore, in a recent Phase I trial, ABC294640 demonstrated clinical activity in CCA patients.

Recruiting, study planned to enroll up to 39 patients

Purpose of the Study – in Layman’s Terms 
  • The goal his clinical research study is to learn if the study drug ABC294640 can help to control advanced, unresectable intra-hepatic, perihilar or extra-hepatic cholangiocarcinoma (CCA). The safety of this drug will also be studied.
Inclusion Criteria – Patients Must:
  • Patients with histologically confirmed intrahepatic, perihilar or extra-hepatic CCA
  • Patients with no more than 2 prior treatments with systemic anti-neoplastic therapy for CCA
  • The tumor is unresectable and not amenable to curative therapy
  • One or more tumors measurable on CT scan per RECIST 1.1
  • Eastern Cooperative Oncology Group (ECOG) performance status 0- 1
  • Life expectancy of at least 3 months
  • Age ≥18 years
  • Signed, written IRB-approved informed consent
  • A negative pregnancy test (if female)
  • Acceptable liver and renal function (as detailed in
  • Acceptable hematologic status (as detailed in
  • Acceptable blood sugar control (Fasting glucose value ≤ 160 mg/dL)
  • Urinalysis: No clinically significant abnormalities
  • Prothrombin time (PT) and partial thromboplastin time (PTT) ≤ 1.5 X ULN after correction of nutritional deficiencies that may have contributed to prolonged PT/PTT
  • For men and women of child-producing potential, willingness to use of effective contraceptive methods during the study (as detailed in
Exclusion Criteria – Patients Must NOT:
  • >2 previous systemic anti-neoplastic regimens for CCA
  • New York Heart Association Class III or IV, cardiac disease, myocardial infarction within the past 6 months, unstable arrhythmia, or evidence of ischemia on ECG
  • Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy
  • Pregnant or nursing women
  • Treatment with radiation therapy, surgery, chemotherapy, or investigational therapy within 28 days prior to study entry
  • Patients who have received any antineoplastic therapy > 28 days prior to starting treatment with ABC294640 and have not recovered from side effects and toxicities of previous therapy
  • Unwillingness or inability to comply with procedures required in this protocol
  • Known infection with human immunodeficiency virus
  • Serious nonmalignant disease (e.g., hydronephrosis, liver failure, or other conditions) that could compromise protocol objectives in the opinion of the investigator and/or the sponsor
  • Patients who were currently receiving any other investigational agent
  • Patients who were receiving drugs that were sensitive substrates of certain CYP450 izoymes that couldn’t have been replaced with other medication (as detailed in
  • Patients who are taking Coumadin or Coumadin derivatives
  • History and physical exam
  • Two questionnaires about mood and mental state
  • Vital signs (heart rate, breathing rate, and blood pressure), weight
  • Blood test to look at overall health and for a pregnancy test (if you are a woman who may be able to have children)
  • Electrocardiogram (ECG) to look at the electrical activity of the heart
  • Urine test
  • Radiographic scans using Computed Tomography (CT) scan or magnetic resonance imaging (MRI) to check the status of the disease
  • Core needle biopsy (CNB) if tumor is accessible
  • Nausea
  • Fatigue
  • Vomiting
  • Diarrhea
  • Feeling of sleepiness or drowsiness
  • Muscle spasms
  • Hot flashes
  • Changes in taste
  • Dizziness
