  • Patent number: 11643461
    Abstract: Humanized, mouse or chimeric anti-CD47 monoclonal antibodies are provided. The antibodies bind to human glycosylated and deglycosylated CD47 with an optimized Koff value, they disrupt the human CD47-SIRP? interaction, and find use in various therapeutic, preventive or diagnostic methods. The invention includes isolated antibodies and derivatives and fragments thereof, pharmaceutical formulations comprising one or more of the humanized or chimeric anti-CD47 monoclonal antibodies; and cell lines that produce these monoclonal antibodies. Also provided are amino acid and nucleotide sequences of the antibodies.

  • Patent number: 11141480
    Abstract: Methods are provided herein for determining and administering optimized dosing of therapeutic anti-CD47 agents, in a schedule that provides safe escalation of dose while achieving a therapeutic level in a clinically effective period of time. The methods can comprise the steps of clearance, escalation, and maintenance. In one embodiment the dosing regimen administers an initial (i) sub-therapeutic dose of an anti-CD47 agent or (ii) a cytoreductive therapy to achieve a safe level of circulating tumor cells for subsequent treatment (clearance); escalating the dose of an anti-CD47 agent until a therapeutic dose is reached (escalation); and maintaining the therapeutic dose for a period of time sufficient to reduce tumor cells in the bone marrow of the patient (maintenance). In an alternative dosing regimen, a patient determined to have a safe level of circulating tumor cells at presentation is treated by the steps of escalation and maintenance without initial clearance.
