Initiation of clinical imaging study

Annexin Pharmaceuticals and Collaborators Initiate a Clinical Study in Patients with Retinal Vein Occlusion (RVO) Using Fluorescent Labelled ANXV.

STOCKHOLM, SWEDEN (September 29, 2021) – Annexin Pharmaceuticals AB (publ) (“Annexin”) announces that its collaborators have received approval from the Dutch regulatory authority to start an innovative clinical molecular imaging study of Annexin’s fluorescent labelled candidate drug ANXV in patients with venous occlusion in the retina (RVO). The trial is managed by TRACER, a CRO specialized in fast-track clinical imaging trials, and is being conducted at the University Medical Center Groningen (UMCG), one of the largest hospitals in the Netherlands.

ANXV holds the potential to rapidly improve retinal blood supply and reduce the risk of blindness and provide other short-term and long-term benefits in the acute setting, prior to the emergence of complications.

In the approved clinical imaging study, by using state-of-the-art clinical NIR fluorescent camera systems, ANXV will be traced in the patient´s eye over time. The results can serve as a confirmation of the specificity of the drug and may lead to e.g. refinement in selection of patients with RVO in future clinical trials.

ANXV has been found safe and tolerable in healthy volunteers in a Phase 1 study and a Phase 2 clinical study in RVO patients is planned to be initiated in the United States later this year.
