Ultivue Expands UltiMapper™ Portfolio of Multiplex Marker Assays for Comprehensive Phenotyping of the Immune Microenvironment and Tissue Immuno-Profiling Research

Share

Ultivue, a leading developer of tissue biomarker identification and quantification assays for translational research and pathology labs, today announced the expansion of its UltiMapper™ multiplex immunofluorescence kit portfolio with a T-reg and MDSC kit. The UltiMapper I/O T-reg kit identifies regulatory T cells and cytotoxic T cells within the tumor context and allows for the phenotyping of activated double positive T cells. The UltiMapper I/O MDSC kit enables the identification and characterization of myeloid derived suppressor cells and allows researchers to differentiate M-MDSC from PMN-MDSC phenotypes.

The new kits have the same benefits of high-throughput whole-slide imaging using conventional IHC equipment and workflows as the previously released UltiMapper I/O PD-L1, UltiMapper I/O PD-1, UltiMapper I/O T-act, and UltiMapper I/O APC kits. “The addition of the T-reg and MDSC kits to the UltiMapper platform now provides researchers with an in-depth view of the sources of overall cell regulation and suppression critical in characterizing the signatures at play within the tumor microenvironment,” said Philippe Mourere, Senior VP of Commercial Operations at Ultivue. “We are very encouraged that the increased breadth and depth of immuno-profiling markers in tissue samples will support further validation of clinically-relevant biomarkers in immuno-oncology, inflammation & immunology, and cancer research.”

Research featuring data generated by the MDSC and T-reg kits will be presented in three of a total of ten posters showcasing the Ultivue technology at the upcoming Society for Immunotherapy of Cancer (SITC) Annual Meeting at The Gaylord National Resort & Convention Center in National Harbor, MD, November 6-10.

Details of the poster sessions can be found below:

Ultivue’s scientific team welcomes the opportunity to interact with the biomedical community during the SITC Annual Meeting at booth #428.

About Ultivue

By developing a single set of novel, proprietary reagents used both for biomarker discovery (higher content, low throughput) and translational use (lower content, high throughput), Ultivue is connecting the insights gained from research directly into the pathology lab. Ultivue’s UltiMapper multiplexed assays applied to tissue biopsy samples enable simultaneous quantitation of multiple biomarkers with sub-cellular spatial resolution and fit completely within traditional IHC workflows. Translational and clinical researchers leverage UltiMapper assays to elucidate complex biology and demonstrate their clinical utility as precision medicine research tools. Ultivue is expanding its UltiMapper assay product portfolio and menu of contract research services to provide a comprehensive set of precision medicine solutions for oncology research and focus in other therapeutic areas.

Ultivue is based in Cambridge, MA. For more information, visit www.ultivue.com

ViiV Healthcare, the global specialist HIV company majority owned by GlaxoSmithKline plc (“GSK”), with Pfizer Inc. and Shionogi Limited as shareholders, today announced that the US Food and Drug Administration (FDA) approved Cabenuva, the first and only complete long-acting regimen for the treatment of HIV-1 infection in adults. Cabenuva is provided as a co-pack with two injectable medicines — ViiV Healthcare’s cabotegravir and Janssen’s rilpivirine — dosed once monthly, as an option to replace the current antiretroviral (ARV) regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies per milliliter [mL]) on a stable regimen, with no history of treatment failure, and with no known or suspected resistance to either cabotegravir or rilpivirine. Prior to initiating treatment of Cabenuva, oral dosing of cabotegravir and rilpivirine should be administered for approximately one month to assess the tolerability of each therapy.1 Lynn Baxter, Head of North America, ViiV H
