TARGETED XTEN CONJUGATE COMPOSITIONS AND METHODS OF MAKING SAME

摘要

The present disclosure provides drug conjugate compositions, and compositions and methods for preparing and using the same. In some embodiments, the present invention relates to targeted conjugate compositions comprising cysteine -containing domains (CCD) linked to targeting moieties, extended recombinant polypeptides (XTEN) and peptide cleavable moieties, with pharmacologically active payload drugs cross-linked to cysteine residues, resulting in compositions that can be cleaved by proteases associated with target tissues. The invention also provides methods of making the targeted conjugate compositions and methods of using the targeted conjugate compositions.
