Publication number: 20140142101Abstract: Interestingly, for prognosis, the significant biomarkers for Gefitinib-treated GBM patients (RTOG 0211) appeared to differ compared to historical, RT and non-Gefitinib-treated GBM patients. In Gefitinib-treated patients, those with higher levels of nuclear pAKT driven by PTEN loss, higher levels of nuclear pMAPK, and lower levels of nuclear pmTOR had significantly worse clinical outcomes. In contrast, in non-Gefitinib-treated patients, patients with PTEN-deficiency, and higher levels of EGFRvIII, total EGFR, IGFR1, NFkB and lower levels of nuclear Survivin appeared to have adverse clinical outcomes, highlighting the treatment-dependency of these biomarkers.Type: ApplicationFiled: October 14, 2013Publication date: May 22, 2014Applicants: Radiation Therapy Oncology Group of the Americal College of Radiology, HistoRx, Inc.Inventors: Arnab CHAKRAVARTI, Robert Pinard, Donald Waldron, Agnes Ang, Marisa P.

Patent number: 8655037Abstract: The present invention relates generally to improved methods of defining areas or compartments within which biomarker expression is detected and quantified. In particular, the present invention relates to automated methods for delineating marker-defined compartments objectively with minimal operator intervention or decision making. The method provides for precise definition of tissue, cellular or subcellular compartments particularly in histological tissue sections in which to quantitatively analyzing protein expression.Type: GrantFiled: December 14, 2012Date of Patent: February 18, 2014Assignee: HistoRx, Inc.Inventors: Jason H. Christiansen, Robert Pinard, Mark Gustavson, Brian Bourke, Dylan M. Reilly, Gregory R. Tedeschi

Patent number: 8605971Abstract: A system and method for automatically and quantitatively determining the optimal dilution of a reagent is provided. In one embodiment, a plurality of dilution sets are received, where each of the dilution sets consist of a different respective dilution value and a respective plurality of immunoassay staining intensity values. A respective dynamic range metric is determining for each of the plurality of dilution sets relative to the respective plurality immunoassay staining intensity values. Having found the respective dynamic range metric, a dilution set having the numerically optimal dynamic range metric is selected and the dilution value of that dilution set is selected as being representative of an optimal dilution level of the reagent for use in a quantitative immunoassay. In one embodiment, a system is provided with a microscope, an image sensor, and processor module configured determine an optimal dilution of a reagent for use in an quantitative immunoassay.Type: GrantFiled: February 3, 2012Date of Patent: December 10, 2013Assignee: HistoRx, Inc.Inventors: Robert Pinard, Gregory R.

Patent number: 8427635Abstract: Methods and apparatus for standardizing quantitative measurements from a microscope system. The process includes a calibration procedure whereby an image of a calibration slide is obtained through the optics of the microscope system. The calibration slide produces a standard response, which can be used to determine a machine intrinsic factor for the particular system. The machine intrinsic factor can be stored for later reference. In use, images are acquired of a target sample and of the excitation light source. The excitation light source sample is obtained using a calibration instrument configured to sample intensity. The calibration instrument has an associated correction factor to compensate its performance to a universally standardized calibration instrument. The machine intrinsic factor, sampled intensity, and calibration instrument correction factor are usable to compensate a quantitative measurement of the target sample in order to normalize the results for comparison with other microscope systems.Type: GrantFiled: January 27, 2012Date of Patent: April 23, 2013Assignee: HistoRx, Inc.Inventors: Jason Christiansen, Robert Pinard, Maciej P.

Patent number: 8417015Abstract: A method and system for automatically evaluating quality of a slide-mounted tissue sample includes receiving a digital image of a magnified portion of the slide-mounted tissue sample. At least one quantitative quality indicator is automatically determined for at least one of the samples, and the digital image of the magnified portion of the sample. Each of the quantitative quality indicators is automatically compared to a respective minimum acceptable quality threshold. The quantitative quality indicators and associated quality thresholds are selected for suitability with an automated quantitative immunoassay. Failure of one or more of the quantitative quality indicators to meet its respective minimum acceptable quality threshold suggests that the sample is unsuitable for subsequent automated pathological evaluation.Type: GrantFiled: March 21, 2012Date of Patent: April 9, 2013Assignee: HistoRx, Inc.Inventors: Robert Pinard, Gregory R.

Publication number: 20120270233Abstract: The present method relates to quantification of prognostic and predictive biomarkers of the PDK/AKT/mTOR pathway, such as GSK3?, S6, CREB, PTEN, AKT and mTOR, using AQUA® analysis to estimate both patient risk and benefit of treatment to patients diagnosed with glioblastoma. Unlike traditional IHC, the AQUA® system is objective and produces quantitative in situ protein expression data on a continuous scale. Taking advantage of the power of the AQUA system, the present method provides a highly robust and standardized diagnostic assays that can be used in the clinical setting to provide physicians with reliable prognostic and predictive information. Glioblastoma multiform (GBM) remains one of the most aggressive human cancers, and biomarkers that provide prognostic and predictive information would be extremely valuable to both the physician and the patient. A patient's risk may be determined using the prognostic biomarkers of the present method.Type: ApplicationFiled: February 10, 2009Publication date: October 25, 2012Inventors: Donald E.
