  • Patent number: 12473356
    Abstract: An scFv-Fc dimer binds and neutralizes TGF?1 selectively and with high affinity and avidity. The scFv region may comprise the same VH and VL domains or CDR regions as metelimumab. The unique combination of their smaller size, high selectivity, potency against TGF?1, and long in vivo half-life makes the scFv-Fc dimers ideal candidates for therapeutic applications.

  • Patent number: 11660328
    Abstract: GLP-2 analogs, such as teduglutide, and fusion proteins of GLP-2 with immunoglobulin are administered before, during or after surgery, particularly resection of the small intestine. When short bowel syndrome develops after surgical resection of the small intestine, parenteral nutrition is usually necessary to compensate for reduced absorption of water and nutrients across the small intestine. GLP-2 analogs and GLP-2 fusion proteins promote growth of small intestine, improve nutrient absorption and can reduce the need for parenteral nutrition after surgery.
