Application Number:	13/109,670
Patent Claims:	1. A method for determining compounds to be used in combination for the treatment of cancer comprising: a) administering a therapeutic combination of a compound having Formula I or II, and a chemotherapeutic agent to HER2-amplified breast cancer cells in laminin-rich, reconstituted basement membrane media, wherein the chemotherapeutic agent targets, binds to, or modulates a HER2 receptor, and b) measuring inhibition of cellular proliferation wherein nonmalignant and malignant mammary cells are discriminated by one or more phenotypic difference selected from cell viability and acinar morphogenesis; wherein the Formula I or II compound is selected from a compound of Formula Ia, Formula Ib and Formula IIa: ##STR00065## or stereoisomers, geometric isomers, tautomers, or pharmaceutically acceptable salts thereof. 2. The method of claim 1 wherein the Formula I or II compound is a compound of Formula Ia. 3. The method of claim 1 wherein the chemotherapeutic agent is an anti-HER2 antibody. 4. The method of claim 3 wherein the anti-HER2 antibody is selected from trastuzumab and pertuzumab. 5. The method of claim 1 wherein the chemotherapeutic agent is selected from erlotinib, docetaxel, 5-FU, gemcitabine, PD-0325901, cisplatin, carboplatin, paclitaxel, bevacizumab, trastuzumab, pertuzumab, temozolomide, tamoxifen, doxorubicin, Akti-1/2 , HPPD, rapamycin, and lapatinib. 6. The method of claim 1 wherein the laminin-rich, reconstituted basement membrane media is Engelbreth-Holm-Swarm extracellular matrix extract. 7. The method of claim 1 wherein the Formula I or II compound is a compound of Formula Ib. 8. The method of claim 1 wherein the Formula I or II compound is a compound of Formula IIa. 9. The method of claim 1, wherein the therapeutic combination comprises a compound having Formula I or II, a first chemotherapeutic agent and second chemotherapeutic agent. 10. The method of claim 2, wherein the chemotherapeutic agent is trastuzumab. 11. The method of claim 2, wherein the chemotherapeutic agent is pertuzumab. 12. The method of claim 2, wherein the chemotherapeutic agent is lapatinib. 13. The method of claim 7, wherein the chemotherapeutic agent is trastuzumab. 14. The method of claim 7, wherein the chemotherapeutic agent is pertuzumab. 15. The method of claim 7, wherein the chemotherapeutic agent is lapatinib.
