BIOPHYTIS STRATEGIC UPDATE: JOINT VENTURE
REGISTRATION FILING SUBMITTED
IN HONG KONG
Paris (France) and Cambridge (Massachusetts,
U.S.), June 2, 2026, at 7:00 a.m CET. – Biophytis SA (Euronext Growth Paris: ALBPS), (“Biophytis”
or the “Company”), a pioneer in the development of transformative therapies impacting longevity, today announced
the submission of the registration filing for its joint venture in Hong Kong with its Asian partners, including Ronghui Renhe Life Technology,
a leading Chinese conglomerate primarily engaged in the manufacturing and distribution of healthcare products.
The joint-venture, named Biophytis Biopharmaceutical
Holding LTD, is intended to accelerate the development and commercialization of BIO101 in sarcopenia across Asian markets. This milestone
represents a significant and anticipated step in the implementation of Biophytis’ Asian development strategy, in line with the announcements
made since the beginning of the year.
“The submission of this registration
filing marks a key milestone in the execution of our Asian strategy. It reflects our commitment to establishing a long-term presence in
this high-potential region. Biophytis Hong Kong will enable us, together with Ronghui Renhe, to strengthen our ability to make our therapeutic
innovations accessible to a greater number of patients, particularly those affected by sarcopenia in China”, said Stanislas
Veillet, CEO of Biophytis.
The official registration of the joint venture
is expected within the coming days. In the following weeks, the respective contributions of the partners will be made, allowing completion
of the transaction (the “Closing”). Biophytis SA will contribute to the joint venture its patents and a license to develop
and commercialize BIO101 in China, Japan and South Korea, while the Asian partners will provide the first tranche of the total committed
financing of $20 million, representing an initial payment of $3 million. This financing is intended to support the clinical and regulatory
development of BIO101 in sarcopenia through marketing authorization in Asia.
The operational launch of the joint venture will
take place immediately following the Closing, with a focus on three strategic priorities: preparing the Phase 3 clinical study of BIO101
in sarcopenia in Asia, submitting the regulatory applications required to initiate this study across the region, and recruiting dedicated
local teams.
