Clinical Trial Summary

• Gefitinib is an orally active epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI). However, 20-30% of patients with EGFR-activating mutations show intrinsic resistance to EGFR-TKI.

• EGFR-mutant non-small cell lung cancer (NSCLC) cells with BIM (BCL2L11) deletion polymorphism show the impaired generation of BIM with the proapoptotic BH3 domain, as well as resistance to EGFR-TKI-induced apoptosis.

• Both BIM polymorphism (12.9%) and EGFR mutations (50% in lung adenocarcinoma) are more prevalent in the East Asian than in Caucasian populations. BIM is a BH3-only proapoptotic member of the Bcl-2 protein family. BIM upregulation is required for apoptosis induction by EGFR-TKI in EGFR-mutant NSCLC.

• Vorinostat (suberoylanilide hydroxamic acid [SAHA]) is a small-molecule inhibitor of histone deacetylase (HDAC) and induces cell differentiation, cell cycle arrest, and apoptosis in several tumor cells. HDAC inhibition can epigenetically restore BIM function and death sensitivity of EGFR-TKI in patients with EGFR-mutant NSCLC in whom resistance to EGFR-TKI is associated with a common BIM polymorphism. EGFR-TKI resistance due to the BIM polymorphism may be able to be circumvented in combination with HDAC inhibition of vorinostat with gefitinib in NSCLC.

Description:

• A cohort of three patients will be treated at each dose level for one cycle (28 days per cycle).

• Treatment will be continued if no DLTs are recorded, and three patients will be treated at the next higher dose level.

• If a patient of the cohort develops a DLT, however, another cohort of three patients will be treated for 1 cycle.

• If more DLTs do not develop, dose escalation continues.

• If more than one of three patients develop a DLT at any dose level, another cohort of three patients will be treated at the next lower dose level.

• If no DLTs are recorded in any of the cohorts, the number of patients per cohort will be increased from 3 to 6.

• Up to 12 patients will be enrolled at the MTD.

• Therefore, the phase II dose for this combined therapy will be defined as the highest dose level at which six patients were treated and less than three DLTs developed.

• Having adequate bone marrow (neutrophil count: 1,500/L, Platelet count: 100,000/L), hepatic (total bilirubin level: 1.5-fold or less of the upper limit of reference value at each institution), renal (creatinine level: 1.5 mg/dL), and respiratory functions (PaO2: 70 torr or SpO2: 94%) within 14 days before entry.

• An estimated life expectancy of 12 or more weeks after the onset of protocol treatment

• Acquisition of written informed consent to participate in the present study from the patient after receiving a satisfactory explanation about study details

Exclusion Criteria:

• Within 4 weeks after the final administration of a cytotoxic anticancer agent. Allowable enrollment when a 7-day washout is completed after the final administration of an EGFR-TKI. Surgery of a primary tumor or to the mediastinum must be completed at least 6 months before the onset of protocol treatment.

• Radiotherapy to the lungs considered necessary at the time of study entry or in the near future.

• Suffering from a severe or poorly controlled systemic disease (e.g., unstable or decompensated respiratory disease, heart disease, renal disease, and liver disease)

• Having an active, as well as poorly controlled or symptomatic metastasis to the central nervous system (involving cerebral edema, spinal cord compression, carcinomatous meningitis, leptomeningeal disease, or invasion due to disease progress). Even with a history of metastasis to the central nervous system or of spinal compression.

• Having an active double cancer.

• Verified HBs antigen positivity or HCV antibody positivity (excluding the case of confirmed HCV-RNA negativity)
