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

Adocia (Euronext Paris: FR0011184241 – ADOC) (Paris: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 final approval by the German (BfArM) regulatory authorities to conduct three clinical studies on BioChaperone® Combo (“BC Combo”).

Tonghua Dongbao is financing the entire program which will be conducted by Adocia, with no impact on Adocia’s cash in hand.

"We are pleased that this innovative drug is one step closer to the millions of Asians patients whose survival is ensured by insulin", said Dr. Chunsheng Leng, Chairman and CEO of Tonghua Dongbao. "Adocia's insulins are fully in line with national policies that encourage the development of innovative biologics, as well as with Tonghua Dongbao's business expansion strategy not only in China but also in major Asian territories covered by our agreement."

We are delighted about the accelerated development for this innovative product, based on our proprietary BioChaperone® platform," said Olivier Soula, Adocia's Deputy Managing Director & R&D Director. "BC Combo, a combination of rapid-acting (lispro), and long-acting (glargine) modern insulins, provides better glycemic control compared to Premixes, easy-to-use insulins that are widely used throughout the world. "

Adocia has demonstrated the clinical benefits of this new combination, notably the reduction of hyperglycemia and hypoglycemia compared to "premix" insulins (insulin with both a rapid-acting and long-acting profile), while maintaining the simplicity of use of a single injection1.

China is the country with the largest number of people with diabetes, with more than 140 million patients, or 1 in 10 people2. China is also one of the largest users of the premix class, which accounts for 65% of the Chinese market by volume3.

The program is taking place in Germany and has been validated by the Chinese authorities to ensure its admissibility in the subsequent development stages.

About BioChaperone® Combo

BioChaperone® (BC) Combo is a fixed combination of two gold standard insulins: long-acting insulin glargine (as contained in the commercial product Lantus®) and rapid-acting insulin lispro (as contained in the commercial product Humalog®). Many patients worldwide prefer to use fixed combinations of long and rapid-acting insulins rather than two separate products (simplicity, reduced number of daily injections).

BC Combo offers a number of advantages over traditional premixes: it reduces the level of postprandial hyperglycemia and the risk of hypoglycemia, and provides better 24-hour basal control.

BC Combo was licensed to Tonghua Dongbao in 2018 in exchange for USD 40 million upfront fee. The agreement also includes future maximum payments of $50 million subject to the achievement of future development milestones and double-digit royalties on sales to be paid to Adocia by Tonghua Dongbao.

BC Combo is patent protected until 2038.
