Lower Dose Chemotherapy Given More Frequent With Avastin to Treat Advanced Non-Squamous Non-Small Cell Lung Cancer

Phase 2

Completed

Conditions: Non-Small Cell Lung Cancer

Interventions: Drug: Paclitaxel
Drug: Gemcitabine
Biological: Avastin

Registration Number: NCT00655850

Lead Sponsor: University of Alabama at Birmingham

Brief Summary: This study is being done to determine the overall progression-free survival (PFS) in patients with advanced or metastatic (Stage IIIB - pleural effusion/IV), non-squamous histology NSCLC treated with metronomic chemotherapy plus Avastin. Also, currently there are no defined markers that predict for clinical benefit to Avastin. Preliminary studies show that there are several observations that support the concept of metronomic chemotherapy with or without the combination of an anti-angiogenic agent. The metronomic chemotherapy with Avastin was shown to enhance the clinical endpoints of the study (response rate and progressive-free survival). Proof of metronomic scheduling requires the development of appropriate intermediate surrogate markers. Several markers will be assessed.

Detailed Description: This is a non-randomized, open-label, pilot Phase II study of metronomic chemotherapy plus Avastin in chemo naïve subjects with advanced non-squamous, non-small cell carcinoma of the lung. The primary endpoint of this study is to assess the overall progression-free survival.

Subjects will be treated with metronomic chemotherapy with paclitaxel and gemcitabine weekly for 3 out of 4 weeks, and Avastin will be administered every 2 weeks. Treatment with metronomic chemotherapy will be expressed as a 4-week cycle. Tumor response to treatment will be evaluated every 8 weeks.

Treatment with metronomic chemotherapy and Avastin will continue for a total of 6 cycles unless there is evidence of disease progression, intolerable toxicity, or withdrawal of consent. Maintenance therapy with Avastin will then continue until disease progression, intolerable toxicity or withdrawal of consent.

Potential biologic parameters to monitor anti-tumor activity of metronomic chemotherapy will be evaluated in 10 subjects. These biomarkers include: sequential determination of blood levels of VEGF, VEGFR2, thrombospondin-1, E-selectin, ICAM-1, and circulating endothelial cells and endothelial precursor cells.

Group	Intervention	Description
Paclitaxel and Gemcitabine + Avastin	Avastin	Patients will be treated with metronomic chemotherapy with paclitaxel and gemcitabine weekly for 3 out of 4 weeks which constitutes one cycle (4 weeks). Avastin will be administered every 2 weeks. Treatment with metronomic chemotherapy and Avastin will continue for a total of 6 cycles unless there is evidence of disease progression, intolerable toxicity, or withdrawal of consent. Maintenance therapy with Avastin will continue until disease progression, intolerable toxicity, or withdrawal of consent.

Avastin will be administered every 2 weeks. Treatment with metronomic chemotherapy and Avastin will continue for a total of 6 cycles unless there is evidence of disease progression, intolerable toxicity, or withdrawal of consent.

Primary Outcome Measures

Name	Time	Method
Progression-Free Survival (PFS)	Baseline to 24 months	Progression Free Survival is defined as the number of days from the day the subject started treatment to the day the subject experiences disease progression in accordance with the Response Evaluation Criteria Solid Tumors (RECIST v1.0). The RECIST criteria indicates progression as a 20% increase in the total tumor measurement over nadir value or the appearance of new lesions.

Secondary Outcome Measures

Name	Time	Method
Number of Participants With Adverse Events	Baseline through duration of treatment an average of 1 year	All adverse events will be recorded as to the grade and relationship to the study drug in accordance with the Common Terminology Criteria for Adverse Events (CTCAE v 3.0)
Overall Survival (OS)	Baseline up to 84 months	Overall Survival is defined as the number of days from the day the subject started treatment to the day the subject experiences death or lost to follow up.
Objective Response Rate	Baseline up to 12 months	The percentage of patients who achieve a complete response and partial response according to RECIST criteria (v1.0).
