Leucoselect Phytosome for Neoadjuvant Treatment of Early Stage Lung Cancer

Lung cancer is the leading cause of cancer death in the country, surpassing deaths caused by colorectal, prostate and breast cancers combined. Veterans are at higher risk of lung cancer due to the higher rate of smoking and environmental toxin exposures. The lack of effective therapy for lung cancer provides the impetus to search for alternative, safe, and effective treatment agents to improve treatment strategy against lung cancer, enhance the probability of a cure and reduce recurrence. Based on encouraging preclinical and clinical findings from an early phase I lung cancer prevention study, using a special formulation of a standardized grape seed extract with enhanced absorption called leucoselect phytosome (LP), the purpose of this new CSR&D Merit Review project is to evaluate the potential usefulness of LP for pre-surgical treatment of early stage lung cancer patients in a phase IIa clinical trial. Findings from this study may set the stage for larger, confirmatory trials in the near future.

Study Overview

• Status: Recruiting
• Conditions: Early Stage Lung Cancer (I and II)
• Intervention / Treatment: Drug: leucoselect phytosome

Detailed Description

The investigators will conduct a phase IIa, single arm study using 2-3 weeks of oral LP treatment for 30 early stage I and II lung cancer patients before surgical resection of their tumors.

Screening: Patients who have suspected early stage lung cancer will be recruited from Pulmonary and Thoracic Surgery clinics prior to diagnostic biopsy.

Following informed consent, which includes allowing the investigators to collect and store some of the samples from the clinical diagnostic procedures as pretreatment samples, such as bronchoscopy, needle aspirations, etc., subject will be screened with history and physical examination (H & P), respiratory/general health questionnaires, food frequency self-assessment questionnaires, review of medical records, including radiographic imaging data, pulmonary function test (PFT), 12-lead EKG, clinical labs (complete blood chemistry panel, blood cell counts, PT, PTT). Most of these diagnostic tests will have already been obtained as a part of the clinical work up. However, new blood tests will be obtained if the last results were over 3 months ago). Blood samples and urine samples will be collected for research. Serum cotinine will be obtained to ascertain smoking status. A portion of the biospecimens (blood, urine, diagnostic samples) collected will be kept for future research at the NMVAHCS in an approved repository. A pregnancy test will be done for a woman who is able to have children.

Intervention: (treatment with study medication). If stage I or II lung cancer is diagnosed from standard clinical practice, the qualified subject will be enrolled into the intervention study to receive 2-3 weeks of LP, taken by mouth once a day, until the lung cancer surgery. At the time of surgery, serial clinical samples, including bronchoscopic and various surgically resected tissues, blood and urine will be collected as post-treatment samples. Pre- and post-treatment samples will be compared to assess how well oral LP has been absorbed, and whether or not there are encouraging anti-cancer changes occurring in the cells and molecules in response to the LP treatment. Once enrolled for intervention, all subjects will be monitored with weekly phone follow up, the safety of LP will be monitored weekly using standard reporting tools (including the NCI common terminology criteria for adverse events Version 5.0 and adverse reaction questionnaires), as well as pre-surgery H&P and blood tests.

Follow up: Post-surgery phone follow up will occur at 3-4 weeks, 6 months and annually for up to 4 years.
