入选标准
- •Participant must be Japanese male or female and aged 18-65 years inclusive at the time of signing the informed consent.
- •Participants who are overtly healthy, as determined by medical evaluation, including medical history, physical examination and baseline safety laboratory studies, according to the judgement of the investigator.
- •Electrocardiograms without clinically significant abnormalities at screening.
- •Able to complete the Follow-up Period through Day 361 as required by the protocol.
- •No medical history of symptomatic C. difficile infection within the prior 2 years.
- •Participants must be medically stable, defined as disease not requiring significant change in therapy or hospitalisation or worsening disease during the 1 month prior to enrolment, with no acute change in condition at the time of study enrolment as judged by the Investigator.
- •Able to understand and comply with study requirements/procedures based on the assessment of the Investigator.
- •Body weight within the range of 45 to 110 kg and body mass index (BMI) within the range of 18.0 to 32.0 kg/m2 (inclusive) at screening.
- •Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
- •Women of no childbearing potential are defined as women who are either permanently sterilised or postmenopausal. Women will be considered postmenopausal if they have been amenorrhoeic for 12 months prior to the planned date of randomisation without an alternative medical cause. The following age-specific requirements apply:
- •Women < 50 years old would be considered postmenopausal if they have been amenorrhoeic for 12 months or more following the cessation of exogenous hormonal treatment and follicle-stimulating hormone levels in the postmenopausal range.
- •Women ≥ 50 years old would be considered postmenopausal if they have been amenorrhoeic for 12 months or more following the cessation of all exogenous hormonal treatment.
- •Female participants of childbearing potential must use one highly effective form of birth control. A highly effective method of contraception is defined as one that can achieve a failure rate of less than 1% per year when used consistently and correctly. Women of childbearing potential who are sexually active with a non-sterilised male partner must agree to use one highly effective method of birth control from 3 months prior to IMP administration and agree to continue through 360 days following IMP administration. Cessation of contraception after this point should be discussed with a responsible physician. Periodic abstinence, withdrawal, spermicides only and lactational amenorrhoea method are not acceptable methods of contraception. Female condom and male condom should not be used together. All women of childbearing potential must have negative results of pregnancy tests prior to dosing.
- •Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the ICF and in this protocol.
排除标准
- •Previous hypersensitivity, infusion-related reaction or severe adverse reaction following mAb administration.
- •Abnormal vital signs after 5 minutes of supine rest, at Screening and/or admission to the study site.
- •Any clinically important abnormalities in laboratory values at the Screening Visit.
- •Clinically significant bleeding disorder or prior history of significant bleeding or bruising following IM injections or venipuncture
- •Primary or acquired immunodeficiency, including HIV infection, or due to drugs, including any course of glucocorticoid therapy exceeding 2 weeks of prednisone or equivalent at a dose of 20 mg daily or every other day within 6 months prior to screening. Any known HIV infection at screening
- •Any known hepatitis B or C virus infection at screening
- •History of malignancy other than treated non-melanoma skin cancers or locally treated cervical cancer in the previous 5 years
- •Any laboratory value in the screening panel that, in the opinion of the investigator, is clinically significant or might confound analysis of study results
- •Absence of suitable veins for blood sampling and IMP administration
- •Receipt of immunoglobulin or blood products, or expected receipt, within 6 months prior to screening or expected to receive during the study
- •Previous receipt of an mAb within 6 months or five antibody half-lives (whichever is longer), prior to informed consent date
- •Receipt of any investigational products in the preceding 90 days or expected receipt of investigational product during the period of study follow-up or concurrent participation in another interventional study
- •Participants with a known hypersensitivity to any component of the IMP
- •History of allergic disease or reactions likely to be exacerbated by any component of the IMP
- •Blood drawn in excess of a total of 400 mL (1 unit) for any reason within 3 months prior to screening or plan to donate blood until the end of follow-up period
- •History of alcohol or drug abuse within the past 2 years that, according to the investigator, might affect the assessments of safety or ability the of participant to comply with all study requirements
- •Deprived of freedom by an administrative or court order, in an emergency setting or hospitalised involuntarily
- •Any condition that, in the opinion of the investigator, might compromise participant safety or interfere with the evaluation of the IMP or interpretation of participant safety or study results. The investigator should follow the standard vital sign ranges
- •Judgement by the investigator that the participant should not participate in the study if the participant is unlikely to comply with study procedures, restriction sand requirements.
- •Previous randomisation in the present study.
- •For females only - currently pregnant or breast-feeding.
- •Employees of the sponsor, study site or any other individuals involved with the conduct of the study or immediate family members of such individuals.
