Abstract: Systems, methods and computer program products for guiding selection of a therapeutic treatment regimen for a known disease such as HIV infection are disclosed. The method comprises (a) providing patient information to a computing device (the computer device comprising: a first knowledge base comprising a plurality of different therapeutic treatment regimens for the disease; a second knowledge base comprising a plurality of expert rules for selecting a therapeutic treatment regimen for the disease; and a third knowledge base comprising advisory information useful for the treatment of a patient with different constituents of the different therapeutic treatment regimens; and (b) generating in the computing device a listing (preferably a ranked listing) of therapeutic treatment regimens for the patient; and (c) generating in the computing device advisory information for one or more treatment regimens in the listing based on the patient information and the expert rules.

Abstract: Methods for treating bacterial infections in the colon, and colonic disorders caused by bacterial infection, using a poorly absorbable form of Rifalazil, are described. Compositions for oral administration, and colonic delivery, of a non- micro-granulated Rifalazil formulation, are also described. Rifalazil is delivered in a form which is poorly absorbed in the gut after oral dosing, and the vast majority of the orally-dosed Rifalazil is not absorbed in the gut. Accordingly, the antibacterial potency in the colonic flora will be enhanced, while absorption and systemic circulation will be reduced, thus reducing potential adverse events.

Abstract: A method for treating a human patient is provided, including administering a radiolabeled form of a therapeutic agent to the patient at a first substantially non-therapeutically-effective dose, wherein pharmacological activity of the therapeutic agent is not due to radioactivity of the therapeutic agent. The method also includes determining information related to a biodistribution of the radiolabeled form of the therapeutic agent in the patient by performing a radioimaging procedure on the patient. Responsively to the information, a decision is made whether or not to treat the patient by administering the therapeutic agent to the patient. If the decision is made to treat the patient, the patient is treated by administering the therapeutic agent to the patient at a second therapeutically-effective dose. If the decision is made not to treat the patient, treatment of the patient with the therapeutic agent is withheld. Other embodiments are also described.

Abstract: The invention features a method of delivering a drug to a diseased cell by linking the drug to a rifamycin derivative, compositions that include drug-rifamycin conjugates of the invention, and methods for treating disease using those compositions.

Abstract: The invention features sulfhydryl rifamycin compositions, methods of making these compositions, and methods for treating disease using these compositions.

Abstract: The present invention relates to novel hepatitis C virus (“HCV”) protease inhibitors or other flavivirus protease inhibitors having the general structure (I) or (II), pharmaceutical compositions containing one or more such inhibitors, methods for preparing such inhibitors, uses of these compounds to treat hepatitis C and related disorders together with their use for their activity towards NS3 serine protease, intermediary compounds for the method of preparation of said compounds and screening methods. The invention specifically discloses novel chemical compounds as inhibitors of the HCV serine protease.

Abstract: The invention features a method of delivering a drug to a diseased cell by linking the drug to a rifamycin derivative, compositions that include drug-rifamycin conjugates of the invention, and methods for treating disease using those compositions.

Abstract: The invention features intravenous dosage formulations of rifalazil and methods of treating disease by intravenous administration of rifalazil.

Abstract: The invention features compositions that include rifamycin analogues formulated with metal salts, metal complexes of rifamycin analogues, and methods for treating disease using these compositions.

Abstract: The invention features sulfhydryl rifamycin compositions, methods of making these compositions, and methods for treating disease using these compositions.

Abstract: The present invention provides compositions and methods for the determination of the presence of specific microorganisms in a sample using the amplification of DNA. The invention further provides compositions and methods that provide an internal standard for the validation of the amplification of DNA. The invention is based on the use of hybrid oligonucleotides that have two domains that are specific for two genetically distinct regions of DNA, e.g., in two genetically distinct microorganisms.
