Eligibility
Key inclusion criteria
1. Normal healthy volunteers, age at screening 18 to 65 years, inclusive.

2. Determined by the Investigator to be in good health, as documented by medical history,
physical examination (including, but not limited to, an evaluation of the
cardiovascular, gastrointestinal, respiratory and central nervous systems), vital sign
assessments, clinical laboratory assessments, and by general observations.

3. Participants must weigh at least 50 kg and have a Body Mass Index (BMI) between 18 and
30 kg/m2 Inclusive.

4. Participants must have clinical laboratory values within <1.5 x upper limit of normal
(ULN) as specified by the testing laboratory, unless deemed not clinically significant
by the Investigator.

5. Consumed an average of no more than 3 drinks per day within the 6 months prior to
administration of study drug (beer [284 mL], wine [125 mL] or distilled spirits [25
mL]).

6. Participants must have a negative urine drug screen /alcohol breath test at screening
and Day -1.

7. Stool sample negative for parasites.

8. Participants must have the ability and willingness to attend the necessary visits to
the study centre.

9. Written informed consent signed prior to entry into the study.

10. Participants must be able to communicate effectively with the study site personnel.

11. Participants using highly effective, double barrier contraception (both male and
female partners) during the study and for 90 days following the dose of AK002
Minimum age
18 Years
Maximum age
65 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
1. Positive testing for human immunodeficiency virus (HIV), hepatitis B surface antigen
(HBsAg), or hepatitis C antibodies (HCV).

2. The participant has any underlying physical or psychological medical condition that,
in the opinion of the Investigator, would make it unlikely that the participant will
complete the study.

3. The participant has evidence of any medical or surgical disease or condition which, in
the opinion of the Investigator, might compromise the haematologic, cardiovascular,
pulmonary, renal, gastrointestinal, hepatic, skeletal, or central nervous system; or
other conditions that may interfere with the absorption, distribution, metabolism or
excretion of AK002, or would place the participant at increased risk.

4. The participant has a history of cancer, except basal cell carcinoma which has been in
remission for at least 5 years prior to Day 1

5. Use of any new drugs (including prescription and over-the-counter drugs and herbal
supplements) within 1 week or 5 half-lives (whichever is longer), prior to
administration of study drug.

6. Use of any prescription medication or neutraceuticals within 30 days of randomization.

7. Use of over-the counter medication (with the exception of paracetamol), vitamin
supplements, or herbal medicines within 7 days of randomization.

8. Participants who initiated immunotherapy 90 days or more before the Screening visit
and have been on a monthly regimen for allergy prevention or treatment may be
considered for inclusion,

9. Use of immunosuppressants, oral corticosteroids, angiotensin converting enzyme (ACE)
inhibitors or beta blockers within 2 weeks or 5 half-lives (whichever is longer),
prior to Screening.

10. Any clinically significant laboratory abnormality or ECG.

11. The participant has a known hypersensitivity to any component of the formulation of
AK002.

12. Absolute neutrophil count <1500/microliter.

13. Aspartate aminotransferase (AST) or alanine transaminase (ALT) >1.5 x ULN unless
deemed not clinically significant by Investigator discretion.

prior to the first study drug administration, or is unwilling to agree to abstain from
alcohol limitations and drugs throughout the study.

15. The participant has used nicotine-containing products (including but not limited to
cigarettes, pipes, cigars, chewing tobacco, nicotine patch or nicotine gum) within 3
months prior to Check-in (Day -1). Cotinine urine test is positive at Screening or
Check-in (Day -1).

16. The participant has poor peripheral venous access.

17. Blood donation or significant blood loss (more than 500 mL) within 60 days

18. Plasma donation within 7 days prior to Day 1.

19. Administration of Investigational Product (IP) in another trial within 30 days prior
to the first study drug administration (or within 5 half lives of the drug, whichever
is longer).

20. Females who are pregnant or lactating or intend to become pregnant before, during, or
within 90 days after participating in this study; or intending to donate ova during
such time period.

21. Surgery within the past three months prior to the first study drug administration
determined by the PI to be clinically relevant.
