Rezolute KOL Event Highlights Significant Unmet Medical Need in Diabetic Macular Edema

REDWOOD CITY, Calif., March 23, 2023 (GLOBE NEWSWIRE) -- Rezolute, Inc. (Nasdaq: RZLT), a clinical-stage biopharmaceutical company dedicated to developing transformative therapies with the potential to shift the treatment paradigms of devastating metabolic diseases, yesterday hosted a virtual key opinion leader (KOL) event focused on the therapeutic landscape of Diabetic Macular Edema (DME), scientific rationale for an oral plasma kallikrein inhibitor (PKI) to target the disease, and the potential of RZ402, the company’s oral PKI, to change the standard of care as a safe, effective, and less invasive treatment option.

“We were honored to have Robert Bhisitkul, MD, PhD, yesterday to share his insights for RZ402 and the current treatment landscape for DME from his perspective as a practicing physician and retina specialist,” said Nevan Charles Elam, Chief Executive Officer and Founder of Rezolute. “The frequency of intravitreal therapeutic injections for diseases like DME prove to be a heavy burden on not only the patient, but the physicians who can’t maintain pace with the treatment regimens. Dr. Bhisitkul’s view on the unmet medical need for an oral treatment option for DME that can improve patient compliance and begin treatment earlier in the course of the disease supports development of RZ402 as a first-line monotherapy.”

“The current clinical treatments of DME, especially treatment regimens utilizing anti-VEGF drugs and second-line steroid treatments, are encumbered with limitations and present an opportunity for RZ402 to truly change the standard of care,” said Dr. Bhisitkul. “I am excited by the potential of RZ402 to be deployed early in disease state and prevent disease progression in patients with DME though its broad spectrum of anti-inflammation and anti-leakage mechanism of actions. An oral alternative to intravitreal injections may reduce or eliminate the need for anti-VEGF injections, expanding the treatment population while simultaneously reducing the treatment burden on the clinic.”

In December 2022, Rezolute announced the initiation of a Phase 2 study of RZ402 in patients with DME. The Phase 2 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 monotherapy over a 12-week treatment period in participants with DME who are naïve to or have received limited anti-VEGF injections. Top line results for the Phase 2 study are anticipated in the first quarter of 2024.

About Diabetic Macular Edema (DME)

Diabetic retinopathy (DR) affects approximately one third of adults with diabetes and can frequently lead to DME, a severe vision-threatening complication of DR characterized by swelling of the retina and thickening of the macula, the part of the eye that is responsible for high-resolution vision. More than a million people currently suffer from DME in the U.S., and this number continues to increase due to the epidemic of diabetes, making it the leading cause of blindness in adults. Anti-vascular growth factor (anti-VEGF) injections into the eye are the current standard of care for DME, requiring repeated administration over recurring periods of time to preserve vision. Due to their invasive route of administration and occasional serious side effects, there is a tendency to delay treatment until later in the disease course, and long-term compliance with eye injection regimens can be difficult for patients. Coupled with inadequate responsiveness in some patients, this leads to overall undertreatment and suboptimal vision outcomes in DME patients.

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 formation of kallikrein, RZ402 is designed to block downstream bradykinin production and the pro-inflammatory, pro-coagulant and fluid leaking contact-activation cascade.

Results from the Phase 1b multiple ascending dose (MAD) study showed that RZ402 was readily bioavailable with dose-dependent increases in systemic exposures. Results at both peak and 24-hour trough substantially exceeded target concentrations based on a combination of in-vitro and in-vivo profiling. 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.

RZ402 has been shown to improve retinal vascular leakage in animal models by up to 90%.

About the Contact Activation Kallikrein-Kinin System

The contact-activation kallikrein-kinin system promotes increased vascular permeability and inflammation via key downstream mediators, including bradykinin, and activation of the intrinsic pathway of coagulation. The pathophysiologic upregulation of this system has been linked to a variety of diseases which are characterized by vascular dysfunction, including diabetic macular edema.
