THX PHARMA (THERANEXUS) AND EXELTIS ACHIEVE KEY MILESTONE TOWARDS THE COMMERCIALIZATION OF TX01
THX Pharma (Theranexus) and Exeltis have reached a pivotal milestone, setting the stage for the regulatory submission of TX01 for Gaucher and Niemann-Pick type C diseases
Lyon, France – Madrid, Spain – October 14, 2025 – 6.30pm CEST – THX Pharma (Theranexus), a pharmaceutical company specializing in treatments for rare neurological diseases, and Exeltis, a global pharmaceutical company within the Insud Pharma group, announce the successful completion of the first major milestone in their license and supply agreement for TX01. This achievement marks a significant step towards bringing TX01 to patients with Gaucher and Niemann-Pick type C diseases.
With this milestone, both companies are on track to submit Marketing Authorization Applications for TX01 as planned, paving the way for commercialization in 2027 in Europe, followed by launches in Latin America and certain Middle Eastern countries.
In addition to the upfront payment received at the signature of the agreement – regarding which Exeltis will not exercise its right to reimbursement, foreseen in the agreement in the event of THX Pharma’s failure to provide the required documentation before October 31, 2025 – THX Pharma is eligible for further regulatory and commercial milestone payments and royalties based on the product’s net sales.
TX01 is a novel formulation of an already approved compound indicated in the treatment of rare neurological diseases such as Gaucher and Niemann-Pick type C. This partnership confirms the commitment of both companies to delivering new therapies and addressing significant unmet medical needs.
Mathieu Charvériat, CEO of THX Pharma, commented: “The timely completion of this milestone demonstrates our commitment to advancing TX01’s regulatory journey. This step brings us closer to the global commercialization of TX01, delivering a transformative therapy for patients with Niemann-Pick type C and Gaucher diseases.”
Salustiano Perez, General Manager of Exeltis, added: “We are pleased to reach this milestone with THX Pharma, the result of a fruitful collaboration. We can now confidently proceed with the plan to apply for TX01’s registration in the first quarter of 2026 and, commercialization in Europe expected as early as 2027.”
