Full description
This Phase I study will evaluate the safety, tolerability and pharmacokinetic properties of escalating single doses of reformulated MMV390048 when administered to healthy men and women of non-childbearing potential (WNCBP) under fasted conditions (Part A).
Primary objectives:
• To evaluate the safety and tolerability of single ascending doses of MMV390048 administered orally to healthy subjects (men and WNCBP) under fasted conditions
Secondary objectives:
• To describe the pharmacokinetics of MMV390048 in healthy subjects (men and WNCBP) after single oral dose administration

Inclusion criteria
Completion of the written informed consent process.
Men or WNCBP age 18 to 55 years, in good health as determined by past medical history, physical examination, vital signs, electrocardiogram, and laboratory tests at screening.
Male subjects agree to use acceptable methods of contraception if the male subject's partner could become pregnant from the time of the first administration of study medication until 130 (90+40) days following administration of the investigational medicinal product. One of the following acceptable methods of contraception must be utilized:
Women subjects must be of non-childbearing potential (WNCBP) as per one of the following definitions:
Haematology, clinical chemistry and urinalysis results at screening that are within the local laboratory reference range or, if outside the range, not clinically significant as judged by the Investigator. More specifically, serum creatinine, hepatic transaminase enzymes (AST ALT), and total bilirubin (unless the subject has documented Gilbert syndrome) should not exceed the upper laboratory norm and haemoglobin must be equal to or higher than the lower limit of the normal range.
Total body weight greater than 50 kg and a body mass index (BMI) within the range of 18 to 32 kg/m2 (inclusive).
Non-smoker or ex-smoker for more than 90 days prior to screening, or smoke no more than 5 cigarettes per day as determined by history. Must be able to abstain from smoking during the inpatient stay.
Willing and able to comply with all scheduled visits, treatment plan, laboratory tests, and other study procedures.
Agree to stay in contact with the study site for the duration of the study and up to 2 weeks following the end of study visit, provide updated contact information as necessary, and have no current plans to move away from the study area for the duration of the study.
Exclusion criteria
Male subjects with a female partner(s) who is (are) pregnant or lactating from the time of the administration of study medication.
Women of childbearing potential, defined as all women physiologically capable of becoming pregnant, including women whose career, lifestyle, or sexual orientation precludes intercourse with a male partner and women whose partners have been sterilized by vasectomy or other means.
Evidence or history of clinically significant haematological, renal, endocrine, pulmonary, gastrointestinal (including gallbladder), cardiovascular (including a family history of long QT syndrome or sudden death), hepatic, psychiatric, neurologic, or allergic disease (including drug or food allergies, anaphylaxis or other severe allergic reactions but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).
History of malignancy of any organ system (other than localised basal cell carcinoma of the skin), treated or untreated, within the past five years, regardless of whether there is evidence of local recurrence or metastases.
Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the subject inappropriate for entry into this study.
Any surgical or medical condition possibly affecting drug absorption (e.g. cholecystectomy, gastrectomy, bowel disease, etc.), distribution, metabolism or excretion.
Previous splenectomy.
A history of photosensitivity.
Subject positive for any of the following
Resting vital signs (measured after 5 minutes in the supine position) at screening, pre-dose (Part A) or pre-inoculation (Part B) outside of the following study-specific normal ranges:
Symptomatic postural hypotension at screening, irrespective of the decrease in blood pressure, or asymptomatic postural hypotension defined as a decrease in systolic blood pressure ≥20 mmHg 2 minutes after changing from a supine to standing position.
A history of clinically significant ECG abnormalities, or any of the following ECG abnormalities at screening, pre-dose (Part A and B) or pre-inoculation (Part B):
Presence of acute infectious disease or fever (i.e. tympanic body temperature ≥38.5 ºC) within five days prior to the first dose of study medication (Part A) or the inoculation administration (Part B).
Use of prescription or non-prescription drugs, herbal and dietary supplements within 14 days or 5 half-lives (whichever is the longer) prior to the first dose of study medication (Part A) or the inoculation administration (Part B). [As an exception, paracetamol may be used at doses of up to 1 g/day (Part A) or 2 g/day (Part B), or ibuprofen up to 1.2 g/day (Part B). Limited use of other non-prescription medications not believed to affect subject safety or the overall results of the study, may be permitted on a case-by-case basis following approval by the sponsor.]
Recipient of any vaccination within 28 days prior to the first dose of study medication (Part A) or the inoculation administration (Part B).
Urine drug screen at screening, pre-dose (Part A) or pre-inoculation (Part B) positive for any drug as listed in Section 9.2.4 unless there is an explanation acceptable to the medical Investigator (e.g. the subject has stated in advance that they consumed a prescription or over the counter product which contained the detected drug) and/or the subject has a negative urine drug screen on retest by the pathology laboratory.
Ingestion of any poppy seeds within the 24 hours prior to the screening blood test.
A positive alcohol breath test at screening, pre-dose (Part A) or pre-inoculation (Part B).
History of regular alcohol consumption exceeding a weekly intake of more than 21 units for males and more than 14 units for females (one unit is equivalent to 8-10 g of ethanol, 285 ml of beer or lager, one glass [125 ml] of wine, or 25 ml of spirits) within 6 months of screening.
History of drug habituation, or any prior intravenous usage of an illicit substance.
Participation in any investigational product study within 12 weeks or five half-lives (whichever is longer) prior to the first dose of the study medication.
Intake of grapefruit, grapefruit juice or grapefruit-related citrus fruits (e.g. Seville oranges, pomelos) within 28 days prior to the first dose of the study medication.
Excessive consumption of beverages containing xanthine bases (e.g. more than 400 mg of caffeine per day, equivalent to approximately 4 cups of coffee).
Pregnant or nursing (lactating) women.
Participation in any research study involving blood sampling (more than 450 ml/ unit of blood), or blood donation to the Australian Red Cross Blood Service (ARCBS) or other blood bank during the 8 weeks prior to IMP administration (Part A) or inoculation (Part B).
Blood donation (excluding plasma donation) of any volume, within 1 month prior to screening.
Medical requirement for intravenous immunoglobulin or blood transfusions.
Subject with poor peripheral venous access.
Subject unwilling or unable to comply with the restrictions described in this protocol.
Any subject who, in the judgment of the Investigator, is likely to be noncompliant during the study, or unable to cooperate because of a language problem or poor mental development.
