Abstract: Described herein are methods and compositions for the treatment of prostate cancer in a subject in need thereof. The prostate cancer may be a castration resistant and an androgen receptor antagonist-resistant prostate cancer. The methods may comprise administering to the subject a CYP17-lyase inhibitor of Formula II.

Abstract: The present invention relates to the use of a toxin moiety (e.g., a chlorotoxin moiety) as a carrier for therapeutic agents, e.g., therapeutic agents that require intracellular uptake to exert their effects. For example, in some embodiments, the present invention provides conjugates comprising a toxin (e.g., a chlorotoxin) moiety and an anti-cancer moiety and methods for using such conjugates to increase cellular uptake and/or increase specificity for cancer cells of the anti-cancer drug. In some embodiments, the present invention provides conjugates comprising a toxin moiety (e.g., a chlorotoxin moiety) and a nucleic acid agent. Also provided are methods of treatment involving administration of such conjugates, and pharmaceutical compositions and kits useful for carrying out such methods of treatment.

Abstract: The present invention provides a system for treating heart disease using a combination of pro-angiogenesis therapy and cellular cardiomyoplasty. The system is particularly useful in treating patients with damaged myocardium due coronary artery disease, myocardial infarction, congestive heart failure, and ischemia. A pro-angiogenic factor (e.g., VEGF) or a means of delivering a pro-angiogenic factor (e.g., a genetically engineered adenovirus, adeno-asssociated virus, or cells) is administered to the heart in order to promote new blood vessel growth in an ischemic or damaged area of the patient's heart. Cells such as skeletal myoblasts or stem cells (e.g., mesenchymal stem cells) with the potential to divide, differentiate, and integrate themselves into the injured myocardium are then administered into the affected area of the heart. By inducing new blood vessels growth in the injured myocardium, the cells are better able to grow and become an integral part of the heart.

Abstract: The present invention provides improved systems and methods for the minimally invasive treatment of heart tissue deficiency, damage and/or loss, especially in patients suffering from disorders characterized by insufficient cardiac function, such as congestive heart failure or myocardial infarction. In certain embodiments, a cell composition comprising autologous skeletal myoblasts and, optionally, fibroblasts, cardiomyocytes and/or stem cells, is delivered to a subject's myocardium at or near the site of tissue deficiency, damage or loss, using an intravascular catheter with a deployable needle. Preferably, the cell transplantation is performed after identifying a region of the subject's myocardium in need of treatment. The inventive procedure, which can be repeated several times over time, results in improved structural and/or functional properties of the region treated, as well as in improved overall cardiac function.
