The Pharmacokinetics and Cardiac Properties of Elacytarabine (CP-4055)
20. september 2013 opdateret af: Clavis Pharma
A Phase I Study of the Human Pharmacokinetics and Cardiac Safety of Elacytarabine
The purpose of the study is to investigate the pharmacokinetics (PK) and cardiac properties of elacytarabine in patients with relapsed or refractory Acute Myeloid Leukaemia (AML).
The efficacy and tolerability of elacytarabine will also be assessed.

Detaljeret beskrivelse
Elacytarabine is an investigational drug which is not commercially available. It consists of a fatty acid that is connected to cytarabine which is commonly used in treatment of AML. Due to the connection to a fatty acid, elacytarabine might have an increased uptake in blast cells and thereby increased efficacy.
The characterisation of the pharmacokinetics of an investigational drug, as well as the cardiac safety are essential. The PK of both elacytarabine and its metabolites will be assessed at defined timepoints before, during and after infusion. The cardiac safety of elacytarabine will be evaluated by triplicate ECG recordings at the same time points as the PK assessments.
Elacytarabine will be given as a continuous infusion for 5 days. The patients may continue with further courses of elacytarabine as long as the patient benefits from treatment with elacytarabine.

- Known positive status for human immunodeficiency virus (HIV)
- Pregnant and nursing patients
- Uncontrolled inter-current illness including, but not limited to, uncontrolled infection, or psychiatric illness/social situations that will limit compliance with study requirements
- Impairment of hepatic or renal function to such an extent that the patient, in the opinion of the investigator, will be exposed to an excessive risk if entered into the clinical study
