New Study Shows High Sensitivity and Specificity for VisionGate’s LuCED Test to Help Detect Lung Cancer Earlier
VisionGate Inc., an in vitro diagnostics company that is developing a revolutionary, non-invasive test for the early detection of lung cancer and other applications, announced that positive results from a clinical study of its LuCED lung test will be highlighted in a poster presentation (Abstract #7547) during the American Society of Clinical Oncology (ASCO) 2014 Annual Meeting at McCormick Place in Chicago on Saturday, May 31, 1:15 to 5 p.m. in S Hall A2, poster board 155. The study demonstrates three major advantages to incorporating the LuCED lung test into the diagnostic algorithm: high sensitivity, exceedingly high specificity and the ability to detect cancer cells in stages I and II.
“Early detection of lung cancer is key – there’s an immense need for safe, effective early detection options to help increase patient survival rates,” said Harvey Pass, M.D., Division Chief of General Thoracic Surgery at NYU Langone Medical Center.
For the study, investigators used VisionGate’s LuCED test with the Cell-CT® cell imaging system to analyze sputum samples from patients with biopsy-confirmed, non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). The results show that VisionGate’s Cell-CT accurately detected lung cancer cells in three-day pooled, spontaneously produced sputum.
In the 30 cases studied, 26 were NSCLC and four were SCLC. Moderate/severe dysplasia or cancer cells were found in 28 of the 30 cases. Half of these cases were either Stage I or Stage II lung cancer with 93.3% sensitivity to early lung cancer.
Importantly, among 5,146 sputum cells from 17 normal patients at high risk for lung cancer, the Cell-CT processed all cells with zero false positive indications for highly specific lung cancer screening. Based on this performance, the lower 95% confidence interval bound for cell specificity is 99.8%.
Today, lung cancer is by far the leading cause of cancer death among both men and women, and more people die of lung cancer than of colon, breast and prostate cancers combined.
“While CT scans are effective at identifying suspicious lesions, more invasive procedures are required to confirm malignancy and the type of lung cancer,” Bonnie J. Addario Lung Foundation’s Bonnie Addario said. “A safe, accurate, non-invasive diagnostic test that could be used earlier in the process would be a significant game changer for the diagnosis of lung cancer. Although early stage lung cancer is typically asymptomatic, the ability to detect it sooner at stage one or two offers the patient a much improved outlook for longer-term survival.”
VisonGate’s LuCED test incorporates its Cell-CT automated system, which harnesses the power of cutting-edge optics and computational technology. It has the capability to capture images very rapidly, rendering scanned objects into 3D digital images. For this particular study, the Cell-CT platform produces clear, detailed, 3D images of cells in sputum, which the system automatically analyzes to identify key features, or biosignatures, associated with potential malignancy. The analysis yields a high score when cancer cells are present.
“Our breakthrough technology platform, the Cell-CT, has demonstrated exquisite sensitivity to rare cancer cells in sputum with exceptionally low false positives, making this the first viable non-invasive, non-radiation test for lung cancer,” VisionGate Founder and Chief Executive Officer Alan C. Nelson, PhD said. “In essence, we’ve added another dimension to pathology by removing human error to overcome hurdles traditionally seen with sputum testing. This is a significant milestone for VisionGate.”
VisionGate is in the final phases of its Clinical Laboratory Improvement Amendments (CLIA) certification and plans to open a best-in-class clinical services laboratory in August 2014 in Phoenix, Arizona. One of the state’s most supported ventures, it was awarded the Arizona Governor’s Celebration of Innovation Award for Innovator of the Year – Start-Up Company in 2011.
