RZLTMEDIUM SIGNALFINANCIAL10-K

RZLT completed Phase 3 enrollment for its lead drug ersodetug while burning through cash at an accelerated pace despite maintaining a strong balance sheet position.

The completion of Phase 3 enrollment in May 2025 represents a critical milestone that moves the company closer to potential regulatory approval, but the increased cash burn rate raises questions about funding runway. The substantial increase in shares outstanding suggests recent equity financing helped bolster the cash position, providing runway through the pivotal trial readout.

FINANCIAL ANALYSIS

RZLT's financial position strengthened considerably with cash growing to $94.1M and total assets expanding 32% to $175.5M, likely reflecting equity fundraising given the 64% increase in shares outstanding. However, operating cash burn accelerated 20% to $69.1M as R&D expenses grew 10% to support the Phase 3 trial, while operating losses widened modestly to $79.9M. The company maintains a strong balance sheet with minimal debt and sufficient cash to fund operations, though the increased burn rate warrants monitoring.

Summary of Clinical Assets Ersodetug Our lead clinical asset, ersodetug, is a potential treatment for hypoglycemia caused by multiple forms of hyperinsulinism.
Ersodetug shows dose dependent pharmacokinetics with a half-life greater than 2 weeks, which has the potential for monthly dosing.
Therefore, we believe that ersodetug is ideally suited as a potential therapy for conditions characterized by excessive insulin or insulin-like levels, and it is being developed to treat hyperinsulinism.
Ersodetug for Congenital Hyperinsulinism sunRIZE Phase 3 Study We completed enrollment in May 2025 of a pivotal Phase 3 clinical study (the sunRIZE study) of ersodetug for the treatment of hypoglycemia in participants with congenital HI, an ultra-rare pediatric genetic disorder characterized by excessive production of insulin by the pancreas.
The study was to enroll approximately 56 participants in more than a dozen countries around the world, inclusive of U.S.
Topline results from the study are anticipated to be available in December 2025, but the specific date of the availability of such results may vary.
The sunRIZE study is a global, randomized, double-blind, placebo-controlled, parallel arm evaluation of ersodetug in participants 3 months of age and older with congenital HI who are not adequately responding to standard of care medical therapies.
Specifically, the study is evaluating the safety and efficacy of ersodetug in participants who are unable to achieve control of low blood sugars and experience hypoglycemia (blood sugars below 70 mg/dL).

Summary of Clinical Assets Ersodetug (formerly RZ358) Our lead clinical asset, ersodetug (formerly RZ358), is a potential treatment for hypoglycemia caused by multiple forms of hyperinsulinism.
Ersodetug shows dose dependent pharmacokinetics with a half-life greater than 2 weeks, which has the potential for twice or even once monthly dosing.
Therefore, we believe that ersodetug is ideally suited as a potential therapy for conditions characterized by excessive insulin levels, and it is being developed to treat hyperinsulinism and low blood sugar.
In cases that are unresponsive to medical management, surgical removal of the pancreas may be required.
In those with diffuse disease where the whole pancreas is affected, a near-total pancreatectomy can be undertaken, although ongoing medical treatment of hypoglycemia is generally required for several years after surgery, before eventual insulin-dependent diabetes ensues.
Food and Drug Administration ( FDA ) approved therapies for all forms of congenital HI and the current standard of care treatments are suboptimal.
Based on the multinational Phase 2b clinical trial ( RIZE ) outcomes and the evidence of benefit in this serious condition with substantial unmet medical need, ersodetug was subsequently granted a priority medicines ( PRIME ) designation by the European Medicines Agency ( EMA ) and an Innovation Passport designation by the UK Innovative Licensing and Access Pathway ( ILAP ) Steering Group for the treatment of congenital HI.
Phase 3 sunRIZE We are actively enrolling a pivotal Phase 3 clinical study (the sunRIZE study) of ersodetug for the treatment of hypoglycemia in participants with congenital HI, an ultra-rare pediatric genetic disorder characterized by excessive production of insulin by the pancreas.
