Use of substituted 2,3-dihydroimidazo[1,2-C]quinazolines
View Patent ↗The present invention relates to: —use of a 2,3-dihydroimidazo[1,2-c]quinazoline compound, or of a pharmaceutical composition containing same, as a sole active agent, or of a combination of a) said compound or a pharmaceutical composition containing said compound and b) one or more further active agents, for the preparation of a medicament for the treatment or prophylaxis of cancer; —combinations of a) said compound and b) one or more further active agents; —a pharmaceutical composition comprising said compound as a sole active agent for the treatment of breast cancer; —a pharmaceutical composition comprising a combination of a) said compound and b) one or more further active agents; —use of biomarkers involved in the modification of Bel expression, HER family expression and/or activation, PIK3CA signaling and/or loss of PTEN for predicting the sensitivity and/or resistance of a cancer patient to said compound and providing a rationale-based synergistic combination as defined herein to increase sensitivity and/or to overcome resistance; and —a method of determining the level of a component of one or more of Bcl expression, HER family expression and/or activation, PIK3CA signaling and/or loss of PTEN.
1. A method for treatment of breast cancer comprising administering to a patient in need thereof a therapeutically effective amount of 2-amino-N-[7-methoxy-8-(3-morpholin-4-ylpropoxy)-2,3-dihydroimidazo[1,2-c]quinazolin-5-yl]pyrimidine-5-carboxamide, or a physiologically acceptable salt, solvate, hydrate, or stereoisomer thereof, wherein the breast cancer is inflammatory breast cancer, triple negative breast cancer, Her2 receptor positive breast cancer, or hormone receptor positive breast cancer.
2. The method according to claim 1 , comprising administering to the patient a therapeutically effective amount of:
2-amino-N-[7-methoxy-8-(3-morpholin-4-ylpropoxy)-2,3-dihydroimidazo[1,2-c]quinazolin-5-yl]pyrimidine-5-carboxamide,
or a physiologically acceptable salt thereof.
3. The method according to claim 2 , wherein cells of the breast cancer do not express Bcl-2.
4. The method according to claim 2 , wherein the breast cancer is inflammatory breast cancer.
5. The method according to claim 2 , wherein the breast cancer is triple negative breast cancer.
6. The method according to claim 2 , wherein the breast cancer is Her2 receptor positive breast cancer.
7. The method according to claim 2 , wherein the breast cancer is hormone receptor positive breast cancer.
