Patent

CA 2263503

The invention pertains to a method of treating or protecting against melanoma that comprises (a) obtaining a melanoma cell line that expresses one or more shared immunodominant melanoma antigens, (b) modifying the melanoma cell line to render it capable of producing an increased level of a citokyne relative to the unmodified cell line, and (c) administering the melanoma cell line to a mammalian host that has melanoma or is at risk for developing melanoma. Preferably the melanoma cell line is allogenic and is not MHC-matched to the host.

Cette invention a trait à des méthodes thérapeutiques ou prophylactiques à l'encontre de mélanomes consistant, (a), à obtenir une lignée cellulaire exprimant un ou plusieurs antigènes hétérophiles immunodominants du mélanome, (b), à modifier la lignée cellulaire du mélanome pour la rendre capable de produire davantage de cytokine que ne le ferait une lignée cellulaire non modifiée et (c), à administrer cette lignée cellulaire à un mammifère hôte porteur d'un mélanome ou risquant d'en développer un. Cette lignée cellulaire qui est, de préférence, allogénique, n'est pas associée à l'hôte en fonction du complexe majeur d'histocompatibilité.
