Pd-l1 binding molecule for cancer treatment
A recently granted patent (Publication Number: US11918649B2) discloses a method for treating cancer in human subjects by administering a PD-L1 binding molecule containing a Shiga toxin effector polypeptide and a binding region that specifically targets the extracellular part of PD-L1. The binding region includes specific amino acid sequences in the heavy chain variable region (VH) and light chain variable region (VL) to ensure effective binding to PD-L1 expressing tumor cells. The method aims to provide a therapeutic benefit in various types of cancer characterized by high mutational burden and solid tumors, including bladder, breast, colon, gastrointestinal, glioma, head and neck, kidney, liver, lung, lymphoma, mesothelioma, myeloma, skin, and urothelial cancers, among others.
Furthermore, the patent claims encompass variations in the Shiga toxin effector polypeptide, VH, VL, and the inclusion of a CD8+ T-cell epitope to enhance the immune response against cancer cells. The method also covers cancers that are refractory to existing treatments like ipilimumab, nivolumab, pembrolizumab, and others, as well as metastatic cancers. The innovative approach of utilizing a PD-L1 binding molecule with specific structural components highlights a promising strategy for addressing the complexities of cancer treatment, potentially offering new avenues for therapeutic interventions in challenging cancer types.
