Company Announcements

• This Phase 3 clinical trial on BioChaperone^® Lispro (THDB0206 injection) conducted in China in people with Type 2 diabetes, successfully demonstrated, in comparison with standard of care Humalog^®:
  • Non inferior HbA1c reduction at 26 weeks (primary endpoint)
  • Significant reduction of the rise of blood glucose after a test meal (key secondary endpoints)
• Mean blood glucose level over the day monitored by 10-point SMBG, an important supportive endpoint, was also significantly decreased, in comparison with Humalog^®
• A series of prespecified subgroup analyses in HbA1c fully support the benefit of the product in long term blood glucose control

LYON, France--(BUSINESS WIRE)--Jul. 25, 2025-- Regulatory News:

Adocia (Euronext Paris: FR0011184241 – ADOC, the “Company”), a clinical-stage biopharmaceutical company focused on the research and development of innovative therapeutic solutions for the treatment of diabetes and obesity, announces that its partner Tonghua Dongbao releases today positive topline results on the Phase 3 clinical trial on BioChaperone^® Lispro (THDB0206 injection), a novel Ultra-Rapid Insulin formulation.

Conducted by Tonghua Dongbao, this Phase 3 study (NCT05834868) was approved by the Chinese Regulatory Authorities (CDE¹). The randomized, open, multicenter study evaluated the safety and efficacy of THDB0206 injection compared to Humalog^® in adults with Type 2 diabetes.

Dr LENG Chunsheng, President of Tonghua Dongbao, said: "THDB0206 injection is a new generation of ultra-rapid insulin that has demonstrated benefits for improving blood glucose control of adults with Type 2 diabetes compared with the standard of care Humalog^®.Tonghua Dongbao is committed to continue to innovate in the treatment of diabetes and obesity."

Olivier Soula , CEO and Co-Founder of Adocia, added: "We are thrilled to share the positive results obtained with BioChaperone^® Lispro on this Phase 3 clinical trial on people with Type 2 diabetes. Given the well-known challenges in showing clinical improvement in this population with a new prandial insulin, we are particularly delighted with these findings. This milestone demonstrates Adocia’s ability to advance its innovative treatments to the final stages of clinical development, within strategic partnerships. We congratulate Tonghua Dongbao’s team for the quality of execution of a large Phase 3 trial of over 1,000 people.”

Results

A total of 1,040 Chinese adults with Type 2 diabetes with inadequate glycemic control and using daily multiple injections of insulin were randomized.

After 26 weeks of treatment, HbA1c decreased significantly in both groups compared to the baseline. The reduction in the THDB0206 injection group was comparable to that of the Humalog^® group, meeting the primary endpoint.

The key secondary endpoints were also demonstrated, with a statistically significant lower rise of blood glucose after a standard meal for the THDB0206 injection group, compared to the Humalog^® group.

The 10-point self-monitoring blood glucose (SMBG) of patients at week 26, an important supportive endpoint of the trial, confirmed the advantage of this product in controlling postprandial blood glucose fluctuations, with a statistically improved daily blood glucose level. A series of prespecified subgroup analyzes of the primary HbA1c endpoint also fully confirmed the benefits of this product in long-term blood glucose control in patients with Type 2 diabetes.

In addition, the safety and tolerability of THDB0206 injection were good. Most of the adverse events were mild or moderate, and the incidence of adverse events and hypoglycemic events were similar to those of Humalog^®.

About BioChaperone^® Lispro

BioChaperone^® Lispro was licensed to Tonghua Dongbaoin 2018, as part of a Licensing Agreement covering China and other Asian countries².

BioChaperone^® Lispro is an Ultra-Rapid Insulin, belonging to the latest generation of prandial insulins. It combines Adocia's proprietary BioChaperone^® technology with insulin lispro, the active ingredient in the standard of care, Humalog^® (Eli Lilly).

This innovative formulation acts significantly faster than earlier insulin generations, effectively reducing post-meal hyperglycemia, which is a key contributor to long-term complications such as retinopathy, diabetic foot ulcers, or kidney failure. Additionally, its rapid elimination minimizes the risk of hypoglycemia, often caused when insulin level remains high after post-meal glucose levels have normalized.

The faster action profile of BioChaperone^® Lispro associated to an excellent local tolerance enhances its compatibility with modern diabetes management systems, particularly insulin pump systems, and provides better integration into advanced treatment algorithms.

Beyond its clinical advantages, the quick onset of BioChaperone^® Lispro improves quality of life by offering greater flexibility in dose timing. Patients can administer insulin at mealtime, or even right-after-mealtime, allowing for more accurate dosing based on known meal timing and content. This reduces the risks of overdosing or underdosing, which can lead to hypo- or hyperglycemia and their associated complications. The simplified dosing process eases the psychological burden on patients and caregivers, significantly alleviating the stress associated with diabetes management.
