BioChaperone^® Lispro in China: Positive Phase 3 results in people with type 1 and type 2 diabetes and marketing authorization filing under preparation

The positive results of the two Phase 3 studies conducted by the partner, Tonghua Dongbao, of the ultra-rapid insulin BioChaperone Lispro in people with type 1 or type 2 diabetes in China were announced in July and October 2025 respectively. ³ ^,

The full results of the clinical trial conducted in people with type 2 diabetes were presented as a commented poster at the American Diabetes Association (ADA) 86^th Scientific Sessions, which took place in New Orleans, USA, on June 5–82026. In the Phase 3 trial study in 1,040 people with type 2 diabetes, BioChaperone Lispro met its primary endpoint, demonstrating a non-inferior HbA1c reduction at 26 weeks versus Humalog^®, with a similar safety and tolerability profile. The full data set showed superior blood glucose control throughout the day and after each meal. In subgroup analyses, superior HbA1c improvements in people using metformin or with baseline HbA1c below 8.5% were observed, with significantly more patients reaching an Hb1Ac target below 7%.

On June 16, 2026, the Company hosted a virtual Key Opinion Leader event where Tim Heise, MD (Profil, Neuss, Germany) joined Olivier Soula, CEO and cofounder, and You-Ping Chan, Head of R&D, to review the Phase 3 results in type 2 diabetes.

Under the agreement with Tonghua Dongbao, a milestone payment of US$20 million would be triggered upon obtaining marketing authorization in China, with subsequent double-digit royalties on sales to Adocia. The marketing authorization filing is in preparation and is under Tonghua Dongbao’s responsibility.

BioChaperone^®GLP-1 – Amylin / BioChaperone^® CagriSema: Combining hormones, new generation of anti-obesity treatments

Direct co-formulation of peptides can present significant physicochemical compatibility challenges. BioChaperone^® technology helps resolve these formulation issues.

Adocia has developed, among other applications, a stable combination of cagrilintide and semaglutide, BioChaperone^®CagriSema, compatible with a multi-use pen. Data generated to date are promising regarding its commercial and manufacturing benefits over the combination of cagrilintide and semaglutide currently being developed by Novo Nordisk now requires each peptide to be in separate chambers, of a single-use pen device. BioChaperone^®CagriSema offers significant manufacturing and usage advantages. Using an existing multi-dose pen makes it possible to replace four auto-injectors for four weeks of treatment with a single pen, and moreover, such a pen offers dosing flexibility, which could represent a future evolution for these hormonal treatments.

An oral presentation on the preclinical results of BioChaperone^® took place at the recent annual congress of Global Drug Delivery & Formulation (DDF), which was held in Berlin, Germany on May 18–20 2026.

The Company has engaged feasibility studies with BioChaperone^® in collaboration with three large pharmaceutical companies whose names are not disclosed. These studies have yielded positive results, enabling to engage in discussions for the next steps with two of them.

To support these studies and potential future clinical trials, a new GMP ⁵ batch of BioChaperone^® has been produced on an industrial scale in Q1 2026.

New long-acting AdoXLong™ platform

Adocia has developed a new platform, AdoXLong™, to address a critical challenge in diabetes and obesity treatments based on GLP-1 agonists, amylin, or other metabolic peptides: extend the duration of action of products currently administered weekly to reach a monthly injection. Beyond the patient comfort it aims to provide, a monthly dosage form is intended to reduce the currently very high discontinuation rate for these treatments observed within the first year and thus address their main limitation, given that all expected benefits are long-term and disappear when treatment is discontinued.

AdoXLong™ technology, for which Adocia has filed a patent application in November 2025 ⁶ , is a long-acting peptide platform composed of a biocompatible polymer chemically linked to the peptides without modifying their mechanisms of action. The technology is designed to offer a long circulating peptide over at least one month.

The technology can be applied to a variety of peptides such as GLP-1, GIP, amylin, or dual/triple agonists – including semaglutide, tirzepatide, cagrilintide – with the possibility to combine these modified peptides with each other.

The patent application is expected to provide worldwide protection until 2046, if granted. The peptides using the technology would also benefit from reinforced intellectual property with extension until 2046. The technology is applicable to both innovative and biosimilar peptides, including semaglutide, which will become off-patent starting in 2026 in certain territories.

Positive preliminary in vitro and in vivo results have been obtained with AdoXL Sema and were shared in a poster presentation at the recent ADA 86^th Scientific Sessions in June 2026. New, superior in vivo results will be presented as a poster at the Obesity Week (November 14-17, 2026, Washington DC, USA).

AdOral^®: Delivering peptides in oral form to replace injections

Adocia has developed an oral delivery technology for peptides and has achieved promising preclinical results with semaglutide (GLP-1). The oral formulations of semaglutide, with Rybelsus^® approved since 2019 for the treatment of type 2 diabetes and the Wegovy^® pill approved by the FDA in December 2025 for the treatment of obesity, represent a major progress in the management of these diseases. Oral delivery is indeed a key factor in increasing patient adherence for those with diabetes and/or obesity.

In 2026, semaglutide is losing patent protection in many countries, and many companies are preparing to launch biosimilars of Ozempic^® (subcutaneous). This situation creates an opportunity for AdOral^®Sema, as this patented product will have freedom to operate, while the Wegovy^® Pill is protected until 2038.

Adocia’s AdOral^® technology has demonstrated so far to have improved bioavailability, suggesting that for the same peptide manufacturing capacity, more patients could be treated at a lower manufacturing cost. AdOral^® technology has also demonstrated a narrower inter-subject variability in terms of oral peptide absorption, suggesting a potential better control of the pharmacokinetic profile of the peptides orally administered via the AdOral^® technology compared to other existing oral-delivery technologies.

The feasibility study conducted with an undisclosed partner for an application to a new incretin with AdOral^® has been completed. The platform potential of AdOral^® has been confirmed by this study. The decision regarding the next steps for the program will depend on the partner’s strategy.

AdoShell^®

AdoShell^® is an immuno-protective biomaterial designed to implant human insulin-secreting cells to provide a cure for type 1 diabetes without immunosuppression.

During the first quarter of 2026, the Company decided to prioritize the development of its BioChaperone^® technology and to suspend activities related to the submission of the clinical trial application for AdoShell^® using human pancreatic islets, which had originally been scheduled for the third quarter of 2026.

However, Adocia could resume this clinical objective as soon as its financial situation and human resources allow it.

The latest preclinical results of AdoShell^® were presented as a poster at the recent ADA 86^th Scientific Sessions in June 2026.

M1Pram

M1Pram is a fixed combination of insulin and amylin analogs aimed at addressing the unmet medical need of obesity in insulin-dependent individuals, in particular people suffering from type 1 diabetes.

In July 2023, Adocia granted Sanofi an exclusive right to negotiate a partnership on M1Pram in return for a payment of €10 million². On July 3, 2026, the Company announced the expiration of Sanofi’s exclusive right to negotiate a partnership for M1Pram¹.
