A Single Ascending Dose Cohort Study of AG-73305 in DME Patients
Completed · Phase 2
Conditions studied: Diabetic Macular Edema
In brief
This is a multi-centered, open-labeled, single ascending-dose-cohort study to evaluate the safety and efficacy of 4 dose cohorts of AG-73305 administered by intravitreal injection in patients with diabetic macular edema (DME). The objectives of this study were to evaluate the safety, tolerability, duration of effect, systemic pharmacokinetic and immunogenicity profiles of ascending doses of AG-73305 administered by intravitreal injection to patients with DME. Pharmacodynamic endpoints (e.g., best-corrected visual acuity \[BCVA\], spectral domain optical coherence tomography \[SD-OCT\], and optical coherence tomography angiography \[OCT-A\]) were evaluated over 6 months post-treatment. The maximum tolerated dose or the highest administered dose was evaluated for future studies.

- Presence of center-involving DME in the study eye with CST ≥ 325 μm
- Visual acuity loss in the study eye attributed to DME with screening and baseline ETDRS BCVA letter score of 20 to 55 (20/400 to 20/80 Snellen equivalent) in the sentinel patients and 35 to 70 (20/200 to 20/40 Snellen equivalent) in the non-sentinel patients
- Cohort 1: Previously treated with an anti-VEGF in the study eye; Cohorts 2, 3, and 4: Previously treated or treatment-naïve to the study eye
You may not qualify if…

- Chronic renal disease
- Any active infection in either eye
- Any anti-vascular endothelial growth factor (VEGF) treatment in the study eye within 6 to 8 weeks prior to Baseline
- Use of Ozurdex (dexamethasone) within 6 months prior to Baseline or any use of Iluvien (fluocinolone acetonide) in the study eye
- Uncontrolled intraocular pressure (IOP), defined as an IOP > 25 mmHg, despite anti-glaucoma medications in the study eye at the time of screening or controlled glaucoma that requires management with > 2 topical hypotensive medications
- Any anti-integrin therapy (e.g., Xiidra) within 60 days before baseline in the study eye
