入选标准
- •Participants must be 18 to 65 years of age inclusive, at the time of signing the informed consent.
- •Participants must have a body weight between 50 and 100 kg, inclusive and body-mass index (BMI) within the range of 18.0 to 32.0 kg/m^
- •Participants must be healthy male or female participant of non-childbearing potential (PONCBP).
- •Participants must be capable of giving signed informed consent prior to any study-specific procedures, which include compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
- •Participants must demonstrate the ability to understand and comply with the study requirements, including attendance for all scheduled visits and adherence to protocol-specified procedures and restrictions. Participants must be willing to remain in close contact with study personnel and reliably record data as instructed.
- •Participants must be in good general health and have no significant ongoing medical conditions, as determined by comprehensive medical history, thorough physical examination, vital signs assessment, 12-lead ECG, and clinical laboratory evaluations (including hematology, biochemistry, and urinalysis).
- •Participants should have baseline (screening) clinical laboratory values (renal, hepatic, and hematological) within normal limits or clinically acceptable to the investigator. A participant with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or
排除标准
- •, or outside the normal reference range for the population being studied, may be included only if the investigator considers that the finding is unlikely to introduce additional risk factors for the participant and will not interfere with the study procedures or endpoints.
- •Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin levels must be within the normal range at Screening.
- •Exclusion Criteria:
- •Participants with a history of malaria infection or who have previously participated in malaria vaccine trials or studies involving experimental anti-malarial monoclonals, small molecule drugs, or experimental malaria challenge are excluded. Participants who have been vaccinated against malaria with an investigational or approved vaccine (e.g., RTS,S and R21/Matrix-M) are excluded.
- •History of allergy to humanized monoclonal antibodies (mAbs) or constituents of the formulation.
- •Any history of anaphylaxis or other severe allergic reactions, or food, or drug allergy that may impact participant safety in the opinion of the investigator.
- •Recent history of, or presence of a current or suspected chronic disease that may impact participant safety, or impact interpretation of clinical study results. This includes illnesses such as (but not limited to) cardiac disease, autoimmune disease, diabetes, progressive neurological disease, severe malnutrition, hepatic or renal disease, epilepsy, chronic obstructive pulmonary disease or asthma (except resolved childhood asthma, which is acceptable). Conditions that in the opinion of the investigator constitute a risk to the individual when taking the study intervention or likely to interfere with the interpretation of data.
- •Have a history of malignant neoplasm (other than localized basal or squamous cell carcinoma of the skin or in situ cervical cancer), treated or untreated, within 5 years of Screening, regardless of whether there is evidence of local recurrence or metastases.
- •Current enrolment or participation in another clinical study.
- •Participation in another clinical study involving any investigational product within the past 90 days or within a period equivalent to 5 half-lives of the investigational drug, whichever is longer, or receipt of experimental non-malaria vaccines or mAbs within the past 12 months prior to signing the informed consent.
- •QT corrected for heart rate by Fridericia's formula (QTcF) >450 msec.
- •Presence or history of cardiac arrhythmias or cardiac disease or a family or personal history of long-QT syndrome.
- •Average heart rate of <40 or >100 beats per minute (bpm).
- •Evidence of previous myocardial infarction or any clinically significant conduction abnormality such as left bundle branch block, atrioventricular (AV) block (2nd degree or higher), Wolff-Parkinson-White syndrome, atrial fibrillation, and atrial flutter. A long-standing right bundle branch block is permitted.
- •Participants cannot take investigational product with biologic agents (such as mAbs including marketed drugs) within 3 months or 5 half-lives (whichever is longer) prior to signing the informed consent.
- •Past or intended use of over the counter or prescription medication, including herbal medications or cannabidiol (CBD)-based products within 14 days prior to administration of study intervention.
- •Recent infection or illness:
- •Participants with any acute illness or infection requiring treatment within 28 days prior to Screening are excluded (but may be re-screened if appropriate).
- •Participants with evidence of active infections, such as Coronavirus disease 2019 (COVID-19) or tuberculosis are excluded.
- •Participants who have received any live vaccines within 3 months prior to Screening or plan to receive such vaccines during the clinical study.
- •Positive drug screen at Screening, including tetrahydrocannabinol, indicating use of known recreational drugs or drugs of abuse.
- •An average weekly alcohol intake of >21 units per week for male participants and >14 units per week for female participants within 6 months prior to Screening. One unit is equivalent to 8 g of alcohol: a half-pint (~240 mL) of beer, 1 glass (125 mL) of wine, or 1 (25 mL) measure of spirits.
- •Any individual who is a current smoker or has a history of cigarette smoking of more than 5 pack years or regular use of tobacco- or nicotine-containing products within 6 months prior to Screening (including e-cigarettes or vaping).
- •Pregnancy and lactation:
- •Participants of childbearing potential (POCBP) are excluded.
- •Pregnant or breastfeeding females are excluded.
- •Participants who have donated 500 mL or more of blood or blood products within 12 weeks before administration of study intervention are excluded.
- •Concomitant conditions:
- •Positive human immunodeficiency virus (HIV) antibody test.
- •Current or chronic history of liver disease or known hepatic or biliary abnormalities (except for clinically established Gilbert's syndrome or asymptomatic gallstones).
- •Presence of hepatitis B surface antigen (HBsAg) at Screening or within 3 months prior to first dose of study intervention.
- •Positive hepatitis C antibody test result at Screening or within 3 months prior to first dose of study intervention.
- •Positive hepatitis C RNA test result at Screening or within 3 months prior to first dose of study intervention.
- •History of severe reactions to IV or SC injections (e.g., anaphylaxis, vasovagal syncope).
