- This Phase 3 clinical trial on BioChaperone Lispro (THDB0206 injection) conducted in China in people with Type 1 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 endpoint)
- Blood glucose level, monitored by 10-point self-monitoring blood glucose (SMBG), was statistically decreased 1 hour after each meal in comparison with Humalog
- These results complete and confirm the positive outcomes previously obtained with THDB0206 injection in people with Type 2 Diabetes
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 second Phase 3 clinical trial on BioChaperone Lispro (THDB0206 injection), a novel Ultra-Rapid Insulin formulation.
Conducted by Tonghua Dongbao, this Phase 3 study was approved by the Chinese Regulatory Authorities (CDE1). The randomized, open, multicenter study evaluated the safety and efficacy of THDB0206 injection compared to Humalogin adults with Type 1 Diabetes.
Mr Li, President of Tonghua Dongbao, said: "We are delighted with the positive results from this Phase 3 clinical trial, which confirm the benefits of THDB0206 injection for improving blood glucose control of adults with Type 1 Diabetes. Tonghua Dongbao is committed to continue to innovate in the treatment of diabetes and obesity."
"We are extremely proud of the Phase 3 results achieved in both Type 1 and Type 2 diabetes: for both populations, we succeeded in improving postprandial blood glucose control after each meal compared to the standard of care. BioChaperone Lispro is the only one of the three ultra-fast insulins to achieve this level of performance across all meals of the day," declaredOlivier Soula, CEO and Co-Founder of Adocia. "This achievement positions Adocia among the few innovators in the field of insulin. The challenges related to the development of metabolic peptides such as insulin, GLP-1, amylin, GIP, and glucagon are comparable. Adocia intends to capitalize on its team's expertise and its rich portfolio of peptide delivery technologies to become a leader in the development of next-generation treatments for diabetes and obesity."
Results
A total of 550 Chinese adults with Type 1 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 first key secondary endpoint was 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. In addition, the study shows a significant trend of blood glucose improvement 2 hours 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, with a statistical improvement 1 hour after each meal (breakfast, lunch, dinner).
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
Those results confirm the positive results obtained with THDB0206 injection in people with Type 2 Diabetes, as communicated in July 20252
About BioChaperone Lispro
BioChaperone Lispro was licensed to Tonghua Dongbaoin 2018, as part of a Licensing Agreement covering China and other Asian countries3. Adocia retains the rights to develop and license BioChaperone Lispro in worldwide markets outside of the territories covered by this agreement.
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.
The contract with Tonghua Dongbao includes a milestone payment of US$20 million, which would be triggered upon obtaining marketing authorization in China, and subsequent double-digit royalties on sales to Adocia. The marketing authorization application is under Tonghua Dongbao's responsibility.
