It’s a little different as this only helps PDC’s for FAP targeted tumours (90%) of those potentially.
So other companies would need to find their own target. Thats always been the problem and ADC’ are not platforms just type specific.
AVA6000 (FAP-Dox): The foundational pre|CISION® peptide drug conjugate patent (background platform IP) expires in 2035. However, AVA6000 is further protected by additional patents covering formulation, manufacturing, patient population, and dosing, and has US Orphan Drug designation, which can provide regulatory exclusivity beyond the patent term.
• AVA6103 (FAP-EXd): The program-specific patent for AVA6103 expires in 2045. The background platform IP for the biologic drug conjugate aspect is co-owned by Avacta and Tufts, expiring in 2041.
Avacta’s new dosing, exposure, and half-life technologies for AVA6000 (FAP-Dox) are protected by additional patents covering formulation, manufacturing, patient population, and dosing. These new patents are separate from the foundational pre|CISION® platform patent, which expires in 2035.
If Avacta’s new IP on dosing and half-life is granted, it can provide up to 20 years of protection from the filing date of each new patent. This means that the exclusivity for AVA6000 could extend beyond 2035-potentially into the late 2030s or even 2040s-depending on when the new patents were filed and granted.
Additionally, in the US, orphan drug designation for AVA6000 could provide 7 years of market exclusivity upon approval, which can run concurrently with or beyond patent protection.
Summary:
The new dosing/exposure/half-life patents could extend AVA6000 protection up to 20 years from their filing dates, potentially well beyond the original 2035 expiry, depending on when these new patents were filed and granted
