Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Must have given written informed consent (signed and dated), and any authorizations required by local law and be able to comply with all study requirements
• Male or female, ≥18 years of age at the time of informed consent
• Females must be non-pregnant and non-lactating, and either surgically sterile (e.g., ≥6 weeks post bilateral salpingectomy, bilateral oophorectomy with or without hysterectomy) or post-menopausal (12 months of spontaneous amenorrhea in females > 55years of age or, in females ≤55 years, or 12 months of spontaneous amenorrhea without an alternative medical, or 12 months with an elevated Follicle Stimulating Hormone (FSH) level Males must either be surgically sterile or abstinent*, or if engaged in sexual relations with a female of child-bearing potential, the subject or the subject's non-pregnant female partner must use a highly effective contraception method from the time of signing the Informed Consent Form (ICF) until at least 30 days after the last dose of study drug; Refer to Section 10.3 for acceptable methods
• Abstinence is only acceptable as true abstinence, i.e., when this is in line with the preferred and usual lifestyle of the subject; periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods). Declaration of abstinence for the duration of a trial and withdrawal are not acceptable methods of contraception (Section 10.3).
• Onset of symptoms of Retinal Vein Occlusion within 23 days prior to informed consent
• The criterion has been removed
• The criterion has been removed
• Clear ocular media and adequate pupillary dilation in the Study Eye to permit high quality retinal imaging
• Willing to refrain from strenuous exercise/activity (for example heavy lifting, weight training, intense aerobics classes etc.) for at least 72 hours prior to study visits
• A negative rapid SARS-CoV-2 (COVID) test on Day 1 prior to initiation of study drug infusion

You may not qualify if…

• Subjects will not be eligible if they have any of the following criteria:
• Study Eye only:
• A severe (≥0.9 log, Grade 3+ or worse) Relative Afferent Pupillary Defect (RAPD)
• Evidence of deep intraretinal hemorrhage involving the center 1mm of the macula
• Evidence of neovascularization
• Ocular disorders/additional eye disease, which in the opinion of the Investigator may confound interpretation of study results, compromise protocol assessments or are likely to require intervention during the study, including, but not limited to, atrophy of the retinal pigment epithelium, sub-retinal fibrosis, organized hard exudate plaque, clinically significant diabetic macular edema, retinal detachment, macular hole, vitreomacular traction, macular epiretinal membrane, clinically significant cataract, vitreal opacities or hemorrhage, glaucoma with documented visual field loss, ischemic optic neuropathy, retinitis pigmentosa or choroidal neovascularization of any cause (e.g., Age-related Macular Degeneration (AMD), ocular histoplasmosis, toxoplasmosis, or pathologic myopia)
• Laser photocoagulation in the study eye within the preceding 6 months prior to the Screening Visit
• Receipt within the past 6 months prior to the Screening Visit of any intraocular surgery (including refractive surgery, cataract surgery), or intravitreal (IVT) injection, or planned intraocular surgery or procedure during the study, unless approved by Medical Monitor or Sponsor
• Recent (6 months) history, or current evidence of ocular herpetic diseases (including herpes simplex virus, varicella zoster or cytomegalovirus), unless approved by Medical Monitor or Sponsor
• Fellow Eye:
• BCVA in the Fellow eye of ≤70 ETDRS letters (approximately 20/40 or less), unless approved by the Medical Monitor or the Sponsor
• Both Eyes:
• Within 6 months prior to the Screening Visit, use of medications known to be toxic to the retina, lens, or optic nerve (e.g., desferoxamine, chloroquine/hydrochloroquine, chlorpromazine, phenothiazines, tamoxifen, and ethambutol)
• Known hypersensitivity or allergy to fluorescein (e.g., bronchospasm, rash, etc.) or to any component of the study products or a contraindication to dilation of the pupil or fixed pupils; mild allergies without angio-edema or treatment need may be acceptable if deemed not to be of clinical significance (including but not limited to allergy to animals or mild seasonal hay fever)
• An IOP greater than 24 mmHg that is not controlled with medication or surgery at the time of the Screening Visit
• Recent (6 months) history of, or presence of uveitis, presence of intraocular inflammation (history of blepharitis is not exclusionary), current ocular infection
• General:
• Unwillingness or inability to attend all study visits and/or perform all procedures/tests/examinations, including follow-up, as specified by this protocol, or unwillingness to cooperate fully with the Investigator
• Any medical or surgical procedure or trauma within 4 weeks prior to the day of Treatment 1 (study drug administration), or planned major surgery within the duration of the study through Day 120, unless approved by Medical Monitor or Sponsor
• 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
• Prior exposure to a recombinant Annexin A5
• History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the Investigator, or history of hypersensitivity to biologics (for example systemically administered recombinant proteins/peptides; a similar drug class to ANXV)
• Uncontrolled hypertension (systolic > 180 mmHg or diastolic > 110 mmHg)
• Current use of any systemically administered anti-angiogenic agent (e.g., bevacizumab, sunitinib, cetuximab, sorafenib, pazopanib) or corticosteroids, approved or 5 half-lives of investigational agent
• Diagnosed untreated systemic metastasis malignancy
