NewcelX Granted Patent in Brazil for NCEL-101 in Type 1 Diabetes, Expanding Global IP Portfolio

Brazil patent complements U.S. patent portfolio for NCEL-101, strengthening global position in the type 1 diabetes market

ZURICH, July 15, 2026 (GLOBE NEWSWIRE) -- NewcelX Ltd. (“NewcelX”; Nasdaq: NCEL), a clinical-stage regenerative medicine company developing stem-cell-derived therapies, today announced that the Brazilian Patent and Trademark Office has issued Patent Number BR 112018010946-0 covering its innovative cell selection and enrichment technology. The patent protects the manufacturing process of its lead clinical compound, NCEL-101, until November 2036.

“The patent grant follows our recently announced successful FDA Type B Pre-IND meeting for NCEL-101, in combination with Eledon’s anti-CD40L monoclonal antibody, tegoprubart, for the treatment of type 1 diabetes, providing a clear regulatory pathway toward initiating clinical trials,” stated Ronen Twito, CEO & Executive Chairman of NewcelX. “Brazil is one of the largest type 1 diabetes markets in Latin America, with approximately 500,000 people living with T1D and prevalence growing at an estimated annual rate of 4.4%¹, underscoring the increasing unmet medical need. Securing patent protection in this strategically important market strengthens NewcelX’s global intellectual property portfolio, enhances future partnering opportunities, and reinforces the Company’s positioning to address a significant commercial opportunity as NCEL-101 advances toward clinical development.”

NCEL-101 leverages a differentiated enrichment process and has demonstrated favorable results in preclinical studies and a supportive safety profile with the following qualities:

• ~60% Beta cells co express insulin and NKX6.1
• MAFA expression, a transcription factor critical for Beta cells maturation and glucose dependent insulin secretion
• 99.98% endocrine lineage, implying minimal, if any, off target non-endocrine population
• More than 96% of cells are non-proliferative, as donor human islets

The Company's technology is unique with its ability to select and enrich the functional and clinically relevant islet cells from the population of differentiated islet-like cells which enables the optimal therapeutic effect with minimal dose.

Recently, the Company successfully completed a Type B Pre-IND meeting with the U.S. Food and Drug Administration (“FDA”), paving the way for the initiation of clinical activities for NCEL-101 in combination with Eledon’s anti-CD40L monoclonal antibody, tegoprubart, for the treatment of type 1 diabetes.
