- Ages 18 to 40 years
- All sexes
- Healthy volunteers accepted
- Adult
Who may be able to join
- Healthy adults between the ages of 18 to 40, inclusive.
- Female subjects must be of non-childbearing potential including pre-menopausal females with documented (medical report verification) hysterectomy or bilateral oophrectomy or postmenopausal defined as 6 months of spontaneous amenorrhea with serum FSH levels > 40 mIU/ml.
- Body weight > 50 kg and body mass index (BMI) between 19 and 30 kg/m2 where:
- A screening electrocardiogram (12-lead ECG) with QTc <450 msec.

- Signed and dated written informed consent prior to admission to the study
- Healthy adult males and females between 18 and 60 years of age, inclusive. Whether a subject is "healthy" will be determined by a responsible physician, based on a medical evaluation including history, physical examination, laboratory tests, cardiac monitoring.
- To be eligible, female subjects must have a negative pregnancy test (i.e. serum bhCG test) and be of:
- non-childbearing potential (i.e. physiologically incapable of becoming pregnant). This includes pre-menopausal females with documented (medical report verification) hysterectomy or double oophrectomy or postmenopausal defined as 12 months of spontaneous amenorrhea or 6 months of spontaneous amenorrhea with serum FSH levels > 40 mIU/mL or 6 weeks postsurgical bilateral oophorectomy with or without hysterectomy, or documented hysterectomy - tubal ligation is not sufficient.
- childbearing potential and agrees to commit to two of the protocol-approved methods of contraception, when used consistently and in accordance with both the product label and the instructions of a physician (and as listed in protocol).
- Male subjects must agree to abstain from or use a condom during sexual intercourse with pregnant or lactating females; or use a condom/spermicide, in addition to having their female partner use another form of contraception, such as an IUD, diaphragm with spermicide, oral contraceptive, inject able progesterone, or sub dermal implant if engaging in sexual intercourse with a female partner who could become pregnant. This criterion must be followed from the time of the first dose of study medication until completion of follow up procedures.
- Body weight ³ 50 kg (110 pounds) for men and ³ 45 kg (99 pounds) for women and body mass index (BMI) between 19 and 31.
- Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and bilirubin within reference range at screening.
- Signed and dated written informed consent prior to admission to the study. The subject is able to understand and comply with protocol requirements, instructions and protocol-stated restrictions
Who cannot join
- Any clinically relevant abnormality identified on the screening history and physical exam, screening 12-lead surface electrocardiogram (ECG), and screening 24-holter cardiac monitoring.
- Any evidence of cardiac disease or other clinically relevant abnormality identified on the screening echocardiography.
- Any clinically relevant abnormality on the clinical safety laboratory tests at screening.
- Positive for Human Immunodeficiency Virus (HIV) antibody, hepatitis B virus surface antigen, or hepatitis C virus antibody at screening.
- Significant cardiac history including but not limited to history of myocardial infarction, angina, heart failure, cardiomyopathy, arrhythmia, myocarditis, hypertrophy (atrial or ventricular), or cor pulmonale.
- Significant central nervous system (e.g., seizures), pulmonary, metabolic, renal, hepatic or gastrointestinal conditions or history of such conditions that, in the opinion of the investigator and/or GSK medical monitor, places the subject at an unacceptable risk as a participant in this trial or may interfere with the absorption, distribution, metabolism or excretion of drugs.

- History of sensitivity to any of the study medications or components thereof.
- History of sensitivity to 4-aminoquinolines (e.g., chloroquine, amodiaquine, or piperaquine).

- Use of prescription or non-prescription drugs, vitamins, herbal and dietary supplements within 14 days or 5 half-lives (whichever is longer) prior to study medication administration, or use of St. John's Wort within 28 days prior to the study medication administration Unless in the opinion of the investigator and sponsor the medication will not interfere with study procedures or compromise safety. By exception, the volunteer may take paracetamol (</ 2 grams/day) up to 48 hours prior to the study medication administration.
- Consumption of grapefruit, grapefruit juice, orange juice or Seville oranges, red wine within 7 days prior to administration of study medication.
- Participation in a clinical study of an investigational or non-investigational drug within 3 months or 5 half-lives (whichever is longer) preceding the study medication administration.

- History of regular alcohol consumption exceeding 14 units/week or 2 units/day for women, or 21 units/week or 3 units/day for men, within 6 months of screening. One unit is equivalent to a half-pint of beer or 1 measure of spirits or 1 glass of wine.
- An unwillingness of male subjects to abstain from sexual intercourse with pregnant or lactating women, or an unwillingness of male subjects to use a condom/spermicide, in addition to having their female partner use another form of contraception such as an IUD, diaphragm with spermicide, oral contraceptives, injectable progesterone, subdermal implants or a tubal ligation, if engaging in sexual intercourse with a female partner who could become pregnant. This criterion must be followed from the time of study medication administration and until 84 days later.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing GSK369796 in people with Malaria, run by GlaxoSmithKline at 1 site in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 15 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety and tolerability (time frame: From Day 1 to follow-up visit). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Sep 2018; AzTrials last refreshed its copy on 29 Oct 2026.
