Abstract: The present invention is directed to methods of monitoring cancer stem cells in patients undergoing cancer therapy to determine whether the cancer therapy is an effective cancer therapy. The present invention relates to methods for monitoring the amount of cancer stem cells prior to, during, and/or following cancer treatment of a patient. In particular, the methods provide measuring the amount of cancer stem cells i) in a sample obtained from a patient and/or ii) in a patient via in vivo imaging, e.g. at different time points before, during or after a treatment regimen for cancer. The change in amount of cancer stem cells over time allows the physician to judge the effectiveness of the treatment regimen and then to decide to continue, alter, or halt the treatment regimen if need be. The present invention also provides kits for monitoring cancer stem cells prior to, during, and/or following cancer treatment of a patient.

Abstract: The present invention provides antibodies that bind to the IL-3 receptor alpha subunit alpha (Il3R?) chain, and compositions comprising such antibodies. The present invention provides methods for inhibiting or reducing an IL3R?-expressing cell population, the methods comprising contacting a population of IL3R?-expressing cells (e.g., cancer cells and/or cancer stem cells) with an antibody that binds to IL3R?. The present invention also provides antibody conjugates comprising an antibody that binds to an IL3R? chain linked to a cytotoxic agent or anticellular agent and compositions comprising such conjugates. The present invention also provides methods for preventing, treating and/or managing a disorder associated with IL3R?-expressing cells (e.g., a hematological cancer), the methods comprising administering to a subject in need thereof an antibody that binds to IL3R?.

Abstract: Provided herein are cancer stem cell targeted cancer vaccines and methods for treating and vaccinating against cancer. Also contained herein are regimens by which cancer stem cell targeted cancer vaccines are administered, such regimens comprising peptides, compositions, immunomodulatory agents, and emulsifiers. Also provided are the patient populations to which the regimens are to be administered, and the dosages, schedules, route of administration for the regimens.

Abstract: Provided herein are methods for treating cancer in a subject comprising administering to the subject a therapeutically effective amount of a peptide derived from the EphA2 protein and/or the IL-13R?2 protein and monitoring the amount of cancer stem cells in said subject. Also provided herein are methods for monitoring the efficacy of an EphA2 peptide-based cancer treatment or an IL-13R?2 peptide-based cancer treatment in a patient with cancer, comprising monitoring the amount of cancer stem cells in said subject prior to, during, and/or following cancer treatment of a patient.
