Trial overview
Official title: Phase I study of colistin methanesulfonate sodium (CMS-Na) -A randomized, double blind, placebo controlled, single and repeat dose study to investigate the safety, tolerability, and pharmacokinetics of CMS-Na in healthy Japanese male subjects -
Trial description: This is a clinical study protocol for a single centre, randomized, double blind, placebo controlled, single and repeat dose study to investigate the safety, tolerability and pharmacokinetics of intravenous dosing of Colistin Methanesulfonate Sodium (CMS-Na) in healthy Japanese male subjects.Eighteen subjects will receive CMS-Na 2.5mg/kg (as colistin activity or 75,000 IU/kg) or placebo as a single dose and twice daily for 2.5 days by intravenous infusion.Blood and urine samples for pharmacokinetics analysis will be taken at regular intervals after dosing. Safety will be assessed by measurement of vital signs, Echocardiogram (ECGs), safety laboratory data, renal function and review of adverse events.

Inclusion and exclusion criteria
Inclusion criteria:
A subject will be eligible for inclusion in this study only if all of the following criteria apply: 1. Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. 2. Japanese ethnic origin defined as having been born in Japan, having four ethnic Japanese grandparents, holding a Japanese passport or identity papers and being able to speak Japanese. Subjects should also have lived outside Japan for less than 10 years at the time of screening. 3. Male between 20 and 55 years of age inclusive, at the time of signing the informed consent. 4. Subjects must agree to use one of the contraception methods listed in Section 8.1. This criterion must be followed from the time of the first dose of study medication until completion of the follow-up visit. 5. Body weight 50 kg(inclusive) and BMI (body mass index)within the range 18.5 – 25 kg/m2 inclusive. 6. AST, ALT, alkaline phosphatase and bilirubin less than 1.5(inclusive)xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%). 7. Subjects with no clinically significant value of CLcr, NAG and beta-2 microglobulin judged by the investigator. 8. Average QTcB or QTcF < 450 msec; or QTc < 480 msec in subjects with Bundle Branch Block taken from triplicate assessments at screening. 9. No clinically active and relevant abnormality on 12-lead ECG at screening. 10. Non-smokers (never smoked or not smoking for >6 months with <10 pack years history [Pack years = (cigarettes per day smoked/20) x number of years smoked]) 11. A signed and dated written informed consent is obtained from the subject 12. The subject is capable of giving informed consent, which includes compliance with the requirements and restrictions listed in the consent form 13. Able to complete all study procedures and planned treatment periods. A subject will not be eligible for inclusion in this study if any of the following criteria apply: 1. The subject has a positive pre-study drug/alcohol screen. A minimum list of drugs that will be screened for include amphetamines, barbiturates, cocaine, opiates and benzodiazepines. The detection of drugs with a legitimate medical use would not necessarily be an exclusion to study participation. 2. A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening. 3. Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones). 4. A positive test for HIV antibody. 5.

Exposure to more than four new chemical entities within 12 months prior to the first dosing day. 8. Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John’s Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study medication, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety. 9. History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation. 10. Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period. 11. Unwillingness or inability to follow the procedures outlined in the protocol. 12. Urinary cotinine levels indicative of smoking or history of regular use of tobacco- or nicotine-containing products prior to screening. 13. The subject has a known allergy or hypersensitivity to colistin or derived components. 14. Subject is kept under regulatory of judicial order in an institution. 15. Subject is mentally or legally incapacitated. 16. The subject’s systolic blood pressure is outside the range of 90-140 mmHg or diastolic blood pressure is outside the range of 45-90 mmHg. 17. Consumption of red wine, seville oranges, grapefruit or grapefruit juice from 7 days prior to the first dose of study medication. To assess any potential impact on subject eligibility with regard to safety, the investigator must refer to the Prescribing Information (see Appendix 2, 3 and 4) for detailed information regarding warnings, precautions, contraindications, adverse events, and other significant data pertaining to the investigational product being used in this study.
