Continuation of TKI With or Without Chemotherapy Beyond Gradual Progression

• Status: Unknown status
• Trial end date: 2015-12-01
• Target enrollment: 0
• Participant gender: All

Summary

There have been reports suggesting that continuous administration of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) is advantageous for patients in which gradual disease progression was observed after the establishment of clinical benefit from EGFR-TKIs. However, whether EGFR TKI with or without chemotherapy provides more survival benefit has not been formally evaluated.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Males and females should be contraceptive during the period of the trial until 8 weeks after the last administration of the drug.

Definition of gradual progression:

1. Slow PD (6 months of partial response/stable disease),

2. Asymptomatic minimal PD,

3. New brain metastasis controlled locally. Patients with asymptomatic, treated brain metastases are eligible for trial participation.

Adequate bone marrow, renal, and liver function are required. Able to comply with the required protocol and follow-up procedures, and able to receive oral medications.

Institutional review board-approved informed consent will be obtained for every patient before initiation of any trial-specific procedure or treatment.

Exclusion criteria： Any unstable systemic disease (including active infection, uncontrolled hypertension, unstable angina, congestive heart failure, myocardial infarction within the previous year, serious cardiac arrhythmia requiring medication, hepatic, renal, or metabolic disease).

Lack of physical integrity of the upper gastrointestinal tract, or malabsorption syndrome, or inability to take oral medication, or have active peptic ulcer disease.

Female subjects should not be pregnant or breast-feeding. Adequate hematological function:

Absolute neutrophil count (ANC) ≥1.5 x 109/L, and Platelet count ≥100 x 109/L.

Adequate renal function: Serum creatinine ≤ 1.5 x ULN, or ≥ 50 ml/min. Adequate liver function :Total bilirubin £ 1.5 x upper limit of normal (ULN) and Alanine Aminotransferase (ALT )and Aspartate Aminotransferase (AST )< 2.5 x ULN in the absence of liver metastases, or < 5 x ULN in case of liver metastases.

Patient assessed by the investigator to be unable or unwilling to comply with the requirements of the protocol.
