A Phase I, Double-Blind, Randomized, Dose Escalation Study to Assess the Safety, Tolerability, and Pharmacokinetics of NNZ-2566 in Healthy Subjects, Following Oral Administration
A Phase I, Double-Blind, Randomized, Dose Escalation Study to Assess the Safety, Tolerability, and Pharmacokinetics of NNZ-2566 in Healthy Subjects, Following Oral Administration
The purpose of this study is to obtain evidence of safety and determine the pharmacokinetics (PK) of NNZ-2566 in healthy volunteers, when administered orally.
Double-blind, placebo-controlled, randomized (with a 6:2 randomization for active versus placebo) safety, dose-escalation, and pharmacokinetic study of NNZ-2566.
Three cohorts will be sequentially dosed, starting with two cohorts receiving a single dose (6mg/kg followed by 30mg/kg). The third cohort will receive two 100mg/kg doses over the course of one day and following a formal safety review the same subjects will then receive two 100mg/kg doses each day for five days.
Inclusion Criteria:
Males: 60.0-100.0 kg, Females: 50.0-100.0 kg (inclusive).
Males: Body mass index (BMI) of 20-30.0, Females: BMI of 18.5-30.0 kg/m2 (inclusive).
Healthy, determined by a medical history with particular attention to:
Adequate venous access in arms to allow collection of blood samples.
Fluent in the English language.
Have voluntarily given written informed consent.
Exclusion Criteria:
Pregnant and lactating females.
History of allergy/hypersensitivity to any of the ingredients of the formulations
History of clinically significant gastrointestinal, hepatic, renal, cardiovascular, dermatological, immunological, respiratory, endocrine, oncological, neurological, metabolic, gynecological, ENT or musculoskeletal disorders, psychiatric disease or hematological disorders.
Any history of asthma during the last 10 years.
Creatinine clearance <65 mL/min.
Any predisposing condition that might interfere with the absorption, distribution, metabolism, and/or excretion of the investigational product.
History of abnormal bleeding tendencies or thrombophlebitis unrelated to venepuncture.
History of hepatitis B, a positive test for hepatitis B surface antigen, a history of hepatitis C, a positive test for hepatitis C antibody, a history of HIV infection or demonstration of HIV antibodies.
Any evidence of organ dysfunction, or any clinically significant clinical laboratory value which, in the opinion of the Investigator would jeopardize the safety of the subject or impact on the validity of the study results, including a liver function test (LFT) >1.5 x upper limit of normal (ULN).
Those who may have difficulty abstaining from alcohol during the 48 hr prior to dose administration and until completion of the Study Exit visit.
History of, or current evidence of, abuse of alcohol or any drug substance, licit or illicit, or positive urine drug screen for drugs of abuse.
Difficulty in abstaining from any prescription medications for 14 days prior to dose administration and for the duration of the study.
Difficulty in abstaining from over-the-counter (OTC) medications or herbal supplements for 14 days prior to dose administration and for the duration of the study, (with the exception of occasional analgesia, vitamin and other nutrient supplement use, at the discretion of the Investigator).
Difficulty in abstaining from food and/or beverages that contain caffeine or other xanthines, (e.g. coffee, tea, cola and chocolate) during the 48 hrs prior to dose administration and for the duration of the study.
History of any psychiatric illness which may impair the ability to provide written informed consent.
Poor compliers or those unlikely to attend.
Receipt of any drug as part of a research study within 30 days of initial dose administration in this study.
Standard blood donation (usually 550 mL) within the 12-week period before dose administration.

Whilst there were no QT/QTc effects seen in the human volunteers at a dose of 20 mg/kg administered intravenously as a 10 min infusion, until the effects of the drug on QT/QTc interval have been formally characterized, the study will use the exclusion criteria defined in International Conference on Harmonisation (ICH) Guideline E14 to exclude subjects with a risk of QT/QTc prolongation, namely:
