EGFR L858R x PI3Kα x PI3Kβ x PI3Kδ

This phase II MATCH screening and multi-sub-trial studies how well treatment that is directed by genetic testing works in patients with solid tumors, lymphomas, or multiple myelomas that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and does not respond to treatment (refractory). Patients must have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.

Preclinical data in lung cancer cell lines showed that EGFR mutation can potentially be a positive predictor for sensitivity to BKM120. Furthermore, when the erlotinib-resistant model H1975 (LR858 and T790M mutation) was treated with BKM120, significant tumor control was observed (Novartis internal data). Therefore, combining BKM120 with erlotinib could potentially down-modulate PI3K-Akt activity resulting in a synergistic effect on cell growth inhibition and enhancing the response to erlotinib.

The safety, tolerability and recommended phase 2 dose (RP2D) of the combination of gefitinib and BKM120 will be determined.
