LYON, France--(BUSINESS WIRE)--Regulatory News:

Adocia (Paris:ADOC) (Euronext Paris: FR0011184241 � ADOC), a clinical-stage biopharmaceutical company focused on the research and development of innovative therapeutic solutions for the treatment of diabetes and other metabolic diseases, announced today the dosing of the first patient with the BioChaperone^� Lispro (�BC Lispro�) Phase 3 study. BC Lispro belongs to the last generation of Ultra-Rapid Insulins together with Fiasp^� (Novo Nordisk^�) and Lyumjev^� (Eli Lilly^�).

�We are proud to be one of the very few companies bringing an innovative insulin from lab to phase 3� said Olivier Soula, Adocia's Deputy CEO & R&D Director, �Congratulations to our partner Tonghua Dongbao for achieving this important milestone. Our product BC Lispro is having a high probability to reach the largest market in the World in term of number of patients."

The Phase 3 program consists of 2 studies treating people with type 1 and type 2 diabetes in 100 clinical centers across China and will enroll a total of c. 1300 patients. The aim of this program is to demonstrate safety and efficacy in comparison to standard of care (Humalog�). Results of this program will then be submitted to the Chinese Regulatory Authorities by Tonghua Dongbao to obtain marketing authorization.

BC Lispro has been licensed-out to Tonghua Dongbao for China and major territories in Western Pacific and South-East Asia Regions that represents 200 million people suffering from diabetes¹ and an estimated 20 million are using insulin every day for their survival.

�I am delighted about this important milestone for the company: as planned Tonghua Dongbao is becoming a specialty biopharma bringing innovative products to Chinese patients.�, indicated Dr. Chunsheng Leng, Chairman and CEO of Tonghua Dongbao. �This is a crucial matter of responsibility for Tonghua Dongbao as Eli Lilly and Novo Nordisk�s Ultra-Rapid Insulins are not currently available in China where million people live with diabetes.�

In 2018, the Chinese insulin market represented more than $3.5 billion² and is forecasted to reach $5 billion² in 2025 due to increased access to medicine, diagnosis, and prevalence of diabetes.

About BioChaperone^� Lispro

BioChaperone^� (BC) Lispro is an Ultra-Rapid Insulin obtained by combining Adocia�s proprietary BioChaperone technology to the rapid-acting market leader insulin lispro (as contained in the commercial product Humalog^�).

Clinical & Quality of Life benefits

Being distributed more rapidly into the bloodstream than previous generations of insulins, BC Lispro reduces after-meal hyperglycemic excursions that are responsible for long-term comorbidities such as retinopathy, diabetic foot ulcer, kidney failure. Moreover, being eliminated faster from the body, BC Lispro may also reduce the risk of hypoglycemic events that are caused when insulin remains too long in the bloodstream after the post-meal hyperglycemia peak has declined.

On top of its direct clinical benefits, the onset of action of BC Lispro results in improved quality of life with more dose-timing flexibility at mealtime. A mealtime injection, or even right-after-mealtime, enables patients to better determine the appropriate insulin dose as the exact timing and contents of their meal is known. This avoids overdosing or delayed dosing, which can lead to hypo- or hyperglycemia respectively, and prevent their severe short and long-term consequences. It significantly reduces the stress and the mental load of those affected by insulin-dependent diabetes and their caretakers which is important in day-to-day life.

Currently, the only drugs providing similar effects in the world are Fiasp^� of Novo Nordisk Co. and Lyumjev^� of Eli Lilly and Company. Fiasp^� and Lyumjev^� are not currently available in China.

BC Lispro was licensed to Tonghua Dongbao in 2018 in exchange for a $10 million upfront fee. The agreement also includes maximum payments of $35 million subjects to the achievement of future development milestones and double-digit royalties on sales to be paid to Adocia by Tonghua Dongbao.

BC Lispro is patent protected until 2033.
