  • Publication number: 20180028629
    Abstract: The present disclosure encompasses immunogenic/therapeutic compositions including Globo series antigens (SSEA-4, Globo H or SSEA-3) glycoconjugates and therapeutic adjuvants (OBI-821 or OBI-834) as well as methods of making and using the same to treat proliferative diseases such as cancer. The therapeutic conjugates include an antigen linked to a carrier. In particular, the therapeutic conjugates include a SSEA-4, Globo H or SSEA-3 moiety and a KLH moiety subunit linked via a linker. The therapeutic compositions are in part envisaged to act as cancer vaccines (single valent, bi-valent or tri-valent vaccines) for boosting the body's natural ability to protect itself, through the immune system from dangers posed by damaged or abnormal cells such as cancer cells. Exemplary immune response can be characterized by reduction of the severity of disease, including but not limited to, prevention of disease, delay in onset of disease, decreased severity of symptoms, decreased morbidity and delayed mortality.

  • Publication number: 20160321394
    Abstract: Disclosed herein are structure-based methods for ligand optimization. The methods involve the selection of a candidate ligand from a structural library based on the binding energy of the ligand with a cancer cell-surface protein. The binding energy is estimated from parameters including polar and mon-polar interactions between the ligand and the surface protein. In this way, candidate ligand(s) with desirable binding affinity to the cancer cell-surface protein can be selected.
