A Phase I Study of Belinostat in Combination With Cisplatin and Etoposide in Adults With Small Cell Lung Carcinoma and Other Advanced Cancers

Study Overview
=================
Brief Summary
-----------------
BACKGROUND: The histone deacetylase (HDAC) inhibitors are a novel class of anticancer agent. These agents lead to the increased acetylation of both histone and non-histone proteins, which leads to rapid cell death in many tumor models. It is thought that the cell death observed with this class of agents may be mediated, in part, through the selective acetylation of histone proteins resulting in increased expression of specific genes. For solid tumors in general, cell death in preclinical models has not translated to activity in patients. For this reason, studies increasingly have combined chemotherapy with HDAC inhibitors to achieve additive and potentially synergistic effects on cancer cells. This protocol will study a continuous infusion of the HDAC inhibitor belinostat in combination with cisplatin and etoposide for patients with advanced cancer. OBJECTIVES: To determine a safe and tolerable phase 2 dose for the combination of belinostat with cisplatin and etoposide. Evaluate molecular markers of HDAC inhibition. ELIGIBILITY: The protocol will be open to all patients with recurrent or advanced cancer (small-cell lung cancer and other advanced cancers) for whom standard therapy offers no curative potential. Age greater than or equal to 18 years ECOG Performance Status 0-2 DESIGN: The study will begin with belinostat 400 mg/m (2)/24h administered by continuous IV infusion on days 1 and 2, cisplatin at 80 mg/m (2) IV on day 2, and etoposide at 100 mg/m (2) IV daily times 3 on days 2 - 4. Dose escalation of belinostat will follow according to traditional 3 patient cohorts. Treatment schedule and dose escalation schemata.

OBJECTIVES: To determine a safe and tolerable phase 2 dose for the combination of belinostat with cisplatin and etoposide. Evaluate molecular markers of HDAC inhibition. To explore the results of administering the dose of belinostat based on the patients' UGT1A1 *28 or *60 genotype, which is a characteristic that may be associated with toxicity. ELIGIBILITY: The protocol will be open to all patients with recurrent or advanced cancer (small-cell lung cancer and other advanced cancers) for whom standard therapy offers no curative potential. Age greater than or equal to 18 years ECOG Performance Status 0-2 DESIGN: The study will begin with belinostat 400 mg/m (2)/24h administered by continuous IV infusion on days 1 and 2, cisplatin at 60 mg/m(2) IV on day 2, and etoposide at 80 mg/ (2) IV daily times 3 on days 2 - 4. Dose escalation of belinostat will follow according to traditional 3 patient cohorts. With Amendment M, dosing will be based on UGT1A1 status, at either 400 mg/m(2) or 600 mg/m(2)

Eligibility Criteria
-----------------
-INCLUSION CRITERIA: Patients must have histologic or cytologic confirmation of cancer for which there is no known standard therapy capable of extending life expectancy. Patients must be greater than or equal to 4 weeks from cytotoxic chemotherapy, except greater than or equal to 6 weeks for mitomycin C or nitrosoureas, and greater than or equal to 8 weeks from prior UCN01; greater than or equal to 4 weeks from monoclonal antibody therapy (cetuximab, bevacizumab); greater than or equal to 4 weeks from prior experimental therapy; greater than or equal 2 weeks from radiation or hormonal therapy; greater than or equal to 2 weeks from sorafenib, sunitinib or temsirolimus treatment. Patients with prostate cancer may continue ongoing LhRH agonist therapy. Patients with bone metastases or hypercalcemia who began intravenous bisphosphonate treatment prior to study entry may continue this treatment while on study. ECOG performance status 0-2. Life expectancy of 3 months or greater. Patients must have acceptable organ and marrow function as defined below: absolute neutrophil count greater than or equal to 1,500/ mm(3) platelets greater than or equal to 100,000/ mm(3) total bilirubin less than or equal to 1.2 mg/dL (except patients with Gilbert's Syndrome) AST (SGOT) and ALT(SGPT) less than or equal to 2.5 times institutional upper limit of normal creatinine less than or equal to 1.5 times institutional upper limit of normal OR - creatinine clearance >50 mL/min/1.73 m(2) for patients with creatinine levels above institutional normal. Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, during the study, and for 3 months after study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. Age greater than or equal to 18 years. Ability to understand and the willingness to sign a written informed consent document. Willing to comply with study procedures and follow-up. EXCLUSION CRITERIA: Patients who have not recovered (CTCAE less than or equal to grade 1) from adverse events due to prior treatments, except for alopecia or base stable grade 2 tinnitus (not interfering with ADL s) or stable grade 2 sensory neuropathy without pain or motor component, and not interfering with ADL s. Patients may not have received more than 2 prior cytotoxic regimens. Patients may not be receiving any other investigational agent with therapeutic anticancer intent. Patients may not have taken another histone deacetylase inhibitor (i.e. valproic acid, vorinostat) for at least 2 weeks prior to enrollment. Patients with history of CNS metastasis may not be enrolled on the study, unless control has been achieved with either radiation or surgical resection at least 3 months prior to enrollment on study. Patients who have had radiation to the pelvis or other bone marrow-bearing sites will be considered on a case by case basis and may be excluded if the bone marrow reserve is not considered adequate (>25% of bone marrow).
