Phase I/II of Oral Vorinostat Combination With Erlotinib in NSCLC Patients With EGFR Mutations With DP After Erlotinib.

Phase 2TerminatedNCT00503971

Spanish Lung Cancer Group33 enrolled

Overview

This is an open label, non-randomized, sequential, phase I/II trial in patients with stage IIIB or IV non-small cell lung cancer (NSCLC) with EGFR mutations after progression to Erlotinib. The study will have two parts. The first part (phase I) will be a dose finding (MTD) study to be implemented at three hospitals. The second part of the study (phase II) will asses the safety and efficacy of the combination. In this second part (phase II) patients will be treated with oral Erlotinib 150 mg P.O daily plus oral Vorinostat administered according to the results of the phase I. The study endpoints to be evaluated will include safety and response rate (RR) as primary endpoints and clinical benefit rate (CBR), time to progression, time to response, response duration and progression free survival as secondary endpoints. All the patients (phase I and II) will be treated until progression disease, unacceptable toxicity or withdrawal of the consent, and will be treated at the discretion of the principal investigator.

SAMPLE: Patients must have histologically-confirmed diagnosis of stage IIIB or IV NSCLC, with prior treatment with Erlotinib. In the phase I study the upper expected number of patients will be eighteen. In the phase II thirty two eligible patients will be included in the study. The enrollment period will be approximately 1.5 years. All patients will be treated with Erlotinib and Vorinostat regimen. Participating hospitals will be those of the Spanish Lung Cancer Group (SLCG). For the phase I portion, there will be 3 sites: Dr. Noemi Reguart and Dr. Rafael Rosell, Institut Catala d'Oncologia, Hospital Germans Trias i Pujol, Badalona (Barcelona, Spain), Dr. Felip Cardenal, Institut Catalan d'Oncologia. Centre Sanitari i Universitari de Bellvitge (CSUB), Hospitalet de Llobregat (Barcelona, Spain) and Dr. Lola Isla, Hospital Clinico Lozano Blesa, (Zaragoza, Spain) For the phase II portion, 10 hospitals (adding 7 to the first 3) from the Spanish Lung Cancer Group (SLCG) will be involved. Hospitals will be included during phase I study. OBJECTIVES AND HYPOTHESES Primary Phase I (1) To determine the MTD of oral vorinostat in combination with erlotinib and to ensure that this treatment is sufficiently safe and tolerable to permit further study. Phase II (1) To determine the percentage of patients free of progression at 12 weeks. Hypothesis: We considered that treatment was effective if we obtained a percentage of patients free of progression at 12 weeks higher than 60%. Secondary (1) To determine the CBR (clinical benefit rate), response rate, time to progression, time to response, response duration, and progression free survival in patients treated with vorinostat and erlotinib in combination. Hypothesis: CBR should be of at least 25% and it will include stable disease for at least 3 months and objective RECIST response for at least 4 weeks. Exploratory endpoints Molecular analysis: Main Objective: analysis of EGFR mutations (in exons 19, 20 and 21) in serum samples at baseline (before treatment), at three months of treatment and at the end of the treatment. Secondary Objectives: retrospective analysis of molecular markers potentially related to drug sensitivity such as E-catherin protein expression, thioredoxin serum levels; Hsp70; methylation of 14-3-3r and CHFR.

Outcomes

Primary Outcomes

Progression Free Survival Rate at 12 Weeks

Progression Free Survival was defined as time from first treatment until progression or death from any cause.

Time frame: From date of first day of treatment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 12 weeks

Maximum Tolerated Dose (MTD) of Oral Vorinostat Phase I

In the phase I, a classic 3 + 3 dose escalation method with 3 patients treated initially at each dose level was used. MTD was determined by testing on dose escalation cohorts: continuous full dose of erlotinib 150 mg orally (p.o.) in a daily administration(QD) and escalating doses of vorinostat p.o. at three dose levels:300 mg QD 7 days every 21 days, 400 mg QD 7 days every 21 days,and 400 mg QD, 7 days every other week. MTD reflects the highest dose of drug that did not cause a Dose-Limiting Toxicity (DLT) in less than or equal to 1 in 6 patients. DLTs were defined as any Vorinostat-related Common Terminology Criteria for Adverse Events Version 3.0 (CTCAE 3.0) Grade 3 or 4 adverse events.

Time frame: Up to 24 weeks for each dosing cohort

Secondary Outcomes

Overall Survival

Overall survival was defined as time from study inclusion until death

Time frame: From the date of study inclusion until end of follow up, up to 36 months.

Time to Progression

The time to progression has been defined as the time that elapses, in months, since the patient begins study treatment until the patient progresses or dies from the disease, the first thing that occurs. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions

Time frame: From the date of randomization until end of follow up, up to 36 months.
