Safety of LEAD Radiotherapy Plus Chemoradiation in Patients With Bulky Stage III Non-Small Cell Lung Cancer

A Phase 1 Study for Evaluating the Safety of Lattice Extreme Ablative Dose (LEAD) Radiotherapy Followed by Standard-Dose Chemoradiation for Patients With Bulky Stage III Non-Small Cell Lung Cancer

The investigators aim to evaluate the safety of delivering a one-time single fraction of Lattice Extreme Ablative Dose (LEAD) radiotherapy followed one day later by standard-dose, conventionally fractionated concurrent chemotherapy and radiation delivered over 6 weeks in patients with bulky stage III non-small cell lung cancer in the setting of a single-arm phase I clinical trial. The investigators hypothesize that the addition of a one-time single fraction of LEAD radiation is safe and feasible, and will not result in additional toxicity above that expected with standard-dose concurrent chemotherapy and radiation alone.

Study Overview

• Status: Terminated
• Conditions: Non-Small Cell Lung Cancer; NSCLC
• Intervention / Treatment: Radiation: Lattice Extreme Ablative Dose (LEAD) Radiation Therapy

Detailed Description

Paarticipants will receive a single fraction of LEAD radiation on day 1, followed one day later by conventionally fractionated concurrent chemoradiation consisting of 60 Gy of radiation delivered to involved sites of disease and a platinum doublet.

The investigational radiation treatment, a single fraction of LEAD radiation, is to be followed by conventionally fractionated radiation delivered concurrently with a standard chemotherapy regimen for stage III non-small cell lung cancer. The following day, patients will begin concurrent chemotherapy and radiation. Chemotherapy will be delivered under the management of the treating medical oncologist. Chemotherapy must be a platinum doublet. Carboplatin and cisplatin are both considered acceptable platinum agents. The use of cisplatin over carboplatin is strongly encouraged, unless the patient has a contraindication to cisplatin. The second agent will be at the discretion of the treating medical oncologist; in the current era, chemotherapy agents are tailored to each patient based on tumor histology, as well as comorbidities that dictate the tolerance of certain chemotherapeutic agents. Chemotherapy will be delivered concurrently throughout radiation therapy, beginning on day 2 of the treatment protocol and on the same day as the start of standard-dose radiation. Weekly regimens or regimens delivered every 3 weeks are acceptable. Additional cycles of consolidation chemotherapy are encouraged and will be given at the discretion of the treating medical oncologist.

7. Patients may not have had surgical resection of the present cancer.
8. Women who are pregnant or breastfeeding will be excluded.
9. Patients must not have any co-morbidity with life expectancy ≤ 6 months, or any uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
10. Patients must not have severe lung disease defined by a history of severe chronic obstructive pulmonary disease (COPD) requiring 3 or more hospitalizations over the past year, or history of interstitial pneumonitis.
11. Patients must not have any concurrent active malignancy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rate of Treatment-related Toxicity in Study Participants	Rate of treatment-related toxicity (serious adverse events, adverse events, etc.) in study participants. Toxicity will be assessed using NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. The two toxicities that will be monitored as primary endpoints are esophagitis and pneumonitis.	Up to 12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame

No new lesions. No disease related symptoms. Normalization of markers and other abnormal lab values. All disease must be assessed using the same technique as baseline.; PR: Greater than or equal to 30% decrease under baseline of the sum of longest diameters of all target measurable lesions. No unequivocal progression of non-measurable disease. No new lesions.	Assessed up to 2 years
Rate of Study Participants Achieving Complete or Partial Response Via PET Response Criteria	Rate of subjects achieving complete response (CR) or partial response (PR) as detected by positron emission tomography (PET) Scan: CR is defined as no residual focal fluorodeoxyglucose (FDG) uptake or decrease in average FDG uptake by more than 80% in all tumor manifestations.; PR is defined as standardized uptake value (SUV) decrease by 0 - 80%.
