Trial Identification

Brief Title: Stereotactic Boost for Locally Advanced Non-Small Cell Lung Cancer

Official Title: Stereotactic Boost for Locally Advanced Non-Small Cell Lung Cancer

Study ID: NCT01222572

Study Description

Brief Summary: In this research study the investigators are looking for the highest dose of a stereotactic radiation boost that can be given safely. Because stereotactic radiation is so precise, the investigators are testing whether it can be used to increase the dose to the primary tumor without significantly increasing the side effects the participant experiences; the goal is to improve the likelihood of killing the tumor.

Detailed Description: Primary Objectives Phase I: Determination of the MTD and dose-limiting toxicities of a stereotactic boost to chemoradiotherapy for stage II/III non-small cell lung cancer. Phase II: Two-year local control rate Secondary Objectives * To evaluate the safety and tolerability of a stereotactic boost to chemoradiotherapy. * To determine the 2-year overall survival. * To determine the 2-year disease-free survival. * To determine the 2-year regional control rate. * To characterize the change in pulmonary function tests over the first 2 years after chemoradiotherapy. Statistical Design The Phase I study followed a standard 3+3 dose escalation design. Three dose levels were evaluated. The DLT observation period was the 7-week chemoradiotherapy period and the subsequent 8-week recovery period. To better study the toxicity at the MTD of the stereotactic boost, there was a 10 patient expansion cohort.The primary endpoint of the phase II portion of the study was two-year local failure rate of the protocol treatment. Local failure was defined as biopsy-proven recurrent disease, or if a biopsy was not attainable, by increasing FDG-avidity on PET-CT on 2 consecutive scans at least 1 month apart. Based on prior studies, a 2-year local failure rate of 15% would be worthy of further study, while a 2-year local failure rate of 35% would not justify further utilization of the treatment. With 32 eligible patients on this study, the treatment will be deemed promising if at least 25 patients are free of local failure at 2 years. Using this design, there was an 8% probability of declaring the treatment worthy of further study if the true 2-year local failure rate was 35%, and a 90% probability of declaring the treatment worthy of further study if the true 2-year local failure rate was 15% by using a one-sided one-sample exact binomial test.
