Abstract
The present invention provides compositions comprising a conjugate of a hapten with a carrier in an ordered and repetitive array, and methods of making such compositions. The conjugates and compositions of the invention may comprise a variety of haptens, including hormones, toxins and drugs, especially drugs of addiction such as nicotine. Compositions and conjugates of the invention are useful for inducing immune responses against haptens, which can use useful in a variety of therapeutic, prophylactic and diagnostic regimens. In certain embodiments, immune responses generated using the conjugates, compositions and methods of the present invention are useful to prevent or treat addiction to drugs of abuse and the resultant diseases associated with drug addiction.
Claims45
A method for treating nicotine addiction in animal, said method comprising administering to an animal a composition comprising an immunologically effective amount of a nicotine hapten-carrier conjugate, said conjugate comprising:
- (a) a virus-like particle of an RNA phage carrier with at least one first attachment site, and
- (b) at least one nicotine hapten with at least one second attachment site;
- wherein said second attachment site is associated through at least one covalent bond to said first attachment site so as to form an ordered and repetitive nicotine hapten-carrier conjugate;
- wherein an immune response to said nicotine hapten is obtained in said animal.
