You may qualify if…

Provided written informed consent
Male or female aged ≥18 and ≤80 years at the time of signing the informed consent form
Confirmed diagnosis of AKC, VKC, or PAC and an average total ACS score of ≥15 calculated from all daily ACS questionnaires completed during the screening period (minimum of 14 daily ACS questionnaires must be completed). Total ACS score is the sum of itching, light sensitivity, eye pain, foreign body sensation, and watering symptom scores (and excludes atopic dermatitis, allergic asthma, and allergic rhinitis scores).
History of topical corticosteroid and/or systemic corticosteroid use for the treatment of allergic conjunctivitis (AKC, VKC, or PAC)
Stable dose(s) of allowed AKC, VKC, or PAC medication(s) during the 14 days prior to Day 1; and commitment to remaining on the same dose(s) of AKC, VKC, or PAC medication(s) for the entire duration of study participation (unless dose modification is due to unforeseen medical necessity) per Section 8.1 and Section 8.2.
Willing and able to comply with the study procedures and visit schedule, including follow-up visits
Negative Screening ova and parasite test
Female patients must be either post-menopausal for at least 1 year with FSH level >40 mIU/mL at Screening or surgically sterile (tubal ligation, hysterectomy or bilateral oophorectomy) for at least 3 months, or if of child-bearing potential, have a negative pregnancy test and agree to use dual methods of contraception, or abstain from sexual activity from Screening until the end of the study, or for 120 days following the last dose of study drug, whichever is longer.
Male patients with female partners of childbearing potential must agree to use a highly effective method of contraception from Screening until the end of the study or for 120 days following the last dose of study drug, whichever is longer. All fertile men with female partners of childbearing potential should be instructed to contact the Investigator immediately if they suspect their partner might be pregnant (e.g., missed or late menstrual period) at any time during study participation.

You may not qualify if…

Known hypersensitivity to any constituent of the study drug
Women who are pregnant, breastfeeding, or planning to become pregnant while participating in the study
Presence of abnormal laboratory values considered to be clinically significant by the Investigator
Any disease or condition (medical or surgical) which, in the opinion of the Investigator, would place the patient at increased risk
History of malignancy, exempting: carcinoma in situ in the cervix, early stage prostate cancer, non-melanoma skin cancers, or cancers that have been in remission for more than 5 years and are considered cured (except for breast cancer). All history of malignancy (including diagnosis, dates, and compliance with cancer screening recommendations) must be documented and certified by the Investigator.
Contact lens use within 48 hours prior to first AK002 dose
Participation in a concurrent interventional study with the last intervention occurring within 30 days prior to administration of study drug (or 90 days or 5 half-lives, whichever is longer, for biologic products)
Treatment with chemotherapy or radiotherapy in the preceding 6 months
Treatment for a clinically significant helminthic parasitic infection within 6 months of screening
Use during the 30 days before Screening (or 5 half-lives, whichever is longer) or use during the Screening period of topical decongestants, topical vasoconstrictors, topical calcineurin inhibitors, topical corticosteroids*, omalizumab, dupilumab, systemic immunosuppressive drugs, or systemic corticosteroids with a daily dose >10 mg prednisone or equivalent per Section 8.1 and Section 8.2
Topical corticosteroids for atopic dermatitis, corticosteroid nasal sprays for rhinitis, and inhaled corticosteroids for allergic asthma are allowed.
Vaccination with live attenuated vaccines within 30 days prior to initiation of treatment in the study, during the treatment period, or vaccination expected within 5 half-lives (4 months) of the study drug administration
Positive hepatitis serology results, except for vaccinated patients or patients with past but resolved hepatitis, at Screening
Positive HIV serology results at Screening
Known history of alcohol, drug, or other substance abuse or dependence
Any other reason that (in the opinion of the Investigator or Medical Monitor) makes the patient unsuitable for enrollment
