Study summary

The primary objective is safety, tolerability and feasibility of systemic intravenous injection of ANXV-800CW in patients with RVO in three dosing-cohorts in a phase I safety study. Secondary objectives are to determine in the pre-mentioned dosing-cohorts the pharmacokinetic profile of ANXV-800CW and to determine phosphatidylserine availability as measured by flow cytometry in whole blood before and after ANXV-800CW administration.

Study design: non-randomized, non-blinded, prospective, mono-center safety/ feasibility dose optimization study

Study population: Patients referred for (sub-)acute blurred vision with the diagnosis of RVO aged 18-85 years, fertile females excluded.

Intervention: All patients will undergo a standard of care ophthalmological work-up to establish the diagnosis of RVO. In the context of this study, Fluoresceine Angiography (FA) will be added to the ophthalmological work-up for all patients. Furthermore, the patients will receive a systemic single-dose injection of ANXV-800CW as part of a optimization study, followed by NIR retinal fluorescence imaging.

Main study parameters/endpoints: The main study parameters studies are safety, tolerability and feasibility of near-infrared fluorescent imaging in the retina of patients with RVO related to the systemic injection of ANXV-800CW.

What researchers measure

Primary outcomes

  1. Safety of near-infrared fluorescent imaging in the retina of patients with RVO related to the systemic injection of ANXV-800CW

    Safety will be assessed by looking at AEs,SAEs, and SUSARs as identified by a questionnaire, but also by looking at vital signs: blood pressure (mmHg), heart rate (beats per minute), temperature (degrees celsius) respiratory rate (breaths per minute)

    Time frame: 1.5 years

  2. Tolerability of near-infrared fluorescent imaging in the retina of patients with RVO related to the systemic injection of ANXV-800CW

    Tolerability will be assessed by looking at AEs,SAEs, and SUSARs as identified by a questionnaire, but also by looking at vital signs: blood pressure (mmHg), heart rate (beats per minute), temperature (degrees celsius) respiratory rate (breaths per minute)

    Time frame: 1.5 years

  3. Feasibility of near-infrared fluorescent imaging in the retina of patients with RVO related to the systemic injection of ANXV-800CW

    Fluorescence intensity (Arbitrary Units) will be measured by using the NIR imaging system and the target to background ratio (reported as the mean, SD, and range) will be calculated from fluorescence images

    Time frame: 1.5 years
