Benefits of technology

[0022]The present method is applicable and adaptable to a large number of heptatoxicity-inducing bioactive agents which produce hepatotoxicity and limit their usefulness because of that hepatotoxicity. The present invention may be used to increase the effectiveness of such bioactive agents (for example by increasing an agent's therapeutic index and/or increasing the dose which may be administered to a patient). Pursuan

Problems solved by technology

The initial event in APAP induced hepatotoxicity is a toxic-metabolic injury leading to hepatocyte death by necrosis and apoptosis.

[0202]The following description of experiments conducted are presented to exemplify the present invention. They are by way of example only and are not to be taken the limit the invention in any way.

Materials and Methods

Animals.

[0203]C57BL / 6 mice were purchased from commercial sources. NALP3 − / −, IL-18 − / − ASC − / −, IPAF − / − and TLR9 − / − mice were backcrossed nine generations onto the C57BL / 6 background. Caspase 1 − / − mice were backcrossed 5-6 generations onto the C57BL / 6 background. These mice have been described previously (39, 40). IL-1β was neutralized in by using the anti-IL-1β antibody from clone B122 (a gift of R. Schreiber, Washington University) at a dose of 0.2 mg / mouse iv twice a day for a total of 48 hours after giving APAP. Control mice received Armenian hamster isotype control antibody. For survival experiments animals were euthanized when they became moribund using criteria of lack of response to stimuli or lack of righting reflex. Animal protocols were approved by the...

Abstract

The present invention relates to the discovery that acetylsalicylic acid (ASA or aspirin), salicylic acid (SA) and related salicylate esters and their pharmaceutically acceptable salts, when coadministered in effective amounts with a drug or other bioactive agent which typically (in the absence of the salicylate compound) produces significant hepatotoxicity as a secondary indication, will substantially reduce or even eliminate such hepatotoxicity. Favorable therapeutic intervention results from the use of the present invention having the effect of reducing hepatotoxicity associated with the administration of certain drugs and other bioactive agents and in certain instances of allowing the administration of higher doses of a compound which, without the coadministration, would produce hepatotoxicity which limits or even negates the therapeutic value of the compound. The invention also relates to methods of reducing the likelihood of a patient at risk for non-alcoholic fatty liver diseases (NAFLD), including non-alcoholic steatohepatitis (NASH), or treating NAFLD or NASH including primary NASH, NASH secondary to liver transplantation (NASH post-liver transplantation) or cirrhosis represent alternative aspects of the present invention.
