Rezolute Completes Enrollment of its Phase 2 Study in Diabetic Macular Edema (“DME”)

Plans to report topline data mid-second quarter 2024

Redwood City, Calif., December 13, 2023 -- Rezolute, Inc. (Nasdaq: RZLT), a clinical-stage biopharmaceutical company committed to developing novel, transformative therapies for serious metabolic and rare diseases, today announced the completion of enrollment in its RZ402 Phase 2 study in diabetic macular edema (“DME”). RZ402 is a selective and potent plasma kallikrein inhibitor (“PKI”) being developed as a potential oral therapy for the chronic treatment of DME.

The study is a multi-center, randomized, double-masked, placebo-controlled, parallel-arm study to evaluate the safety, efficacy, and pharmacokinetics of RZ402 administered as a once daily oral monotherapy over a 12-week treatment period and four-week follow-up in participants with DME who are naïve to, or have received limited anti-VEGF injections. Eligible participants were randomized equally to either a placebo control arm or one of three RZ402 active treatment arms at doses of 50, 200, and 400 mg.

This proof-of-concept study was designed to enroll up to 100 participants to evaluate activity and safety by individual dose level and in pooled fashion. In the fourth quarter 2023, based on considerable momentum, the Company elected to keep enrollment open into December to include as many eligible patients as possible. Screening is now complete, and final study enrollment is expected to be approximately 95 participants. Additionally, although each participant has an assigned study eye, it is expected that a meaningful number of non-study eyes will be eligible for evaluation. Since DME results from a systemic vascular complication associated with diabetes, it commonly affects both eyes. RZ402, as an orally available systemic therapy, has the potential to treat both eyes simultaneously. As a result of the extension of the enrollment period, the Company now plans to report topline results in the middle of the second quarter 2024, rather than the end of the first quarter 2024.

“The strong commitment from our participating clinical trial sites and equally strong conclusion of study enrollment are indicative of the high demand and unmet medical need for an oral therapy and new mechanistic target for the chronic treatment of DME,” remarked Dr. Brian Roberts, Chief Medical Officer of Rezolute. “We are incredibly excited and thankful for the level of the engagement that we have received from the retina community and wish to thank the study investigators, their study staff, and the patient participants who trailblaze new therapies. We very much look forward to reporting the results from this study in the coming months.”

The principal endpoints of the trial include (i) the change in central subfield thickness of the macula, as measured by Spectral Domain Ocular Coherence Tomography, (ii) the change in best-corrected visual acuity as measured by the early treatment diabetic retinopathy scale, (iii) the repeat dose pharmacokinetics of RZ402 in patients with DME, and (iv) the safety and tolerability of RZ402.

DME is a result of a systemic microvascular complication of diabetes, manifesting in the retinal blood vessels behind the eyes, and therefore commonly affects both eyes. With currently available intravitreal anti-VEGF therapies, two separate eye injections are required, or treatment of one eye or both eyes may be deferred, when both eyes are affected. Although a single study eye was identified for primary evaluation, Rezolute plans to take advantage of the binocular exposure that is achieved with its oral therapy and will also evaluate key endpoints in the non-study eye.

About RZ402

RZ402 is a selective and potent PKI being developed as a potential once-daily oral therapy for the chronic treatment of DME. By inhibiting the activation of kallikrein, RZ402 is designed to block bradykinin production and its resulting effects on vascular leakage and inflammation.

RZ402 has been shown to reduce and prevent retinal vascular leakage in animal models by up to 90%. Results from a Phase 1b multiple ascending dose (MAD) study showed that RZ402 was readily bioavailable with dose-dependent increases in systemic exposures. RZ402 concentrations substantially exceeded target efficacious concentrations based on a combination of in-vitro and in-vivo pharmacology studies in animals, supporting the potential as a once daily therapy for DME. RZ402 was generally safe and well-tolerated, including at higher doses than previously tested in the single ascending dose (SAD) study. There were no serious adverse events, adverse drug reactions, or identified risks.
