US Patent 12071516 Polymeric stabilizing formulations

The disclosure pertains to the field of treatment of patients with implantable delivery devices for long-term release of therapeutic agents. In particular, the disclosure provides devices and methods for the stabilization of the therapeutic agents inside the device for the duration of the implantation. The devices control the long-term release of the therapeutic agents by using a nanoporous membrane. The stabilization is achieved by using high-molecular weight stabilizers of a size that is larger than the diameter of the pores of the membrane, thereby preventing the release of the stabilizers.
