Study Description
Brief Summary
This is an adaptive, randomised, double-blind, single-centre, placebo-controlled phase I, First in Human study designed to evaluate the safety, tolerability and pharmacokinetics of single and multiple intravenous dosing of ANXV in healthy male subjects.

Phase 1 |
Detailed Description
This First in Human study is divided in two parts. Part I, Single Ascending Dose (SAD), will explore safety, tolerability and PK of single intravenous doses of ANXV. Part II, Multiple Ascending Dose (MAD), will explore safety, tolerability and PK of multiple doses (five consecutive daily doses) of intravenous ANXV.
The objectives of this study are:
Primary objective:
- To evaluate the safety and tolerability of single/multiple ascending doses of ANXV in healthy male subjects.
Secondary objective:
- To determine the PK profile of single/multiple ascending doses of ANXV in healthy male subjects.
Exploratory objectives:
- To evaluate ADA to ANXV and other relevant parameters.

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Willing and able to give written informed consent for participation in the study.
-
Healthy male subject aged 18-50 years inclusive at screening.
-
BMI ≥ 18.0 and ≤ 30.0 kg/m2 and weight at least 50 kg and no more than 100 kg at screening.
-
Overtly healthy based on medical history, physical findings, vital signs, ECG and laboratory values at the time of screening, as judged by the Investigator.
-
Male subjects must be willing to use condom or be vasectomised or practice sexual abstinence to prevent pregnancy and drug exposure of a partner, and refrain from donating sperm from the date of dosing until 3 months after (last) dosing with the IMP. Their female partner of child-bearing potential are expected to use contraceptive methods with a failure rate of < 1% to prevent pregnancy (combined [oestrogen and progestogen containing] hormonal contraception associated with inhibition of ovulation [oral, intravaginal, transdermal], progestogen-only hormonal contraception associated with inhibition of ovulation [oral, injectable, implantable], intrauterine device [IUD] or intrauterine hormone-releasing system [IUS]).
Exclusion Criteria:
-
History of any clinically significant disease or disorder which, in the opinion of the Investigator, may either put the subject at risk because of participation in the study, or influence the results or the subject's ability to participate in the study.
-
Any clinically significant illness, medical/surgical procedure or trauma within 4 weeks of the first administration of IMP.
-
Malignancy within the past 5 years with the exception of in situ removal of basal cell carcinoma.

-
Any history of coronary artery disease or cerebrovascular accident.
-

Any history of or active peptic ulcer disease.
-
Any clinically significant disease affecting the respiratory tract (e.g. obstructive and restrictive respiratory disease, chronic respiratory disease such as alveolitis, inflammatory respiratory disease, autoimmune respiratory disease, present respiratory infections, pulmonary vascular disease) that would influence the results of the study or the subject's ability to participate in the study, as judged by the Investigator.
-
eGFR (based on plasma-creatinine) outside of normal range at screening or known renal impairment (≤70 mL/min).
-
