Our Histoprofile®- T-reg light panel is ready for use in your clinical trials

Accurate characterization of the tumor micro-environment when tissue sample access is limited can be an important challenge in the field of immuno-oncology. The balance and tumor infiltration of T cell subpopulations are of particular interest and its importance has been repeatedly demonstrated in the literature. T cells are important immune effector cells and are therefore preferred targets for immuno-modulation.

Conventional T cells can be broadly classified as helper (Th), cytotoxic (Tcyto), memory or regulatory (Treg) cells. Tcyto cells ensure optimal immune responses against invading microbes and tumor antigens. Under homeostatic conditions, Tregs promote peripheral tolerance. However, within tumors, Tregs can supress Tcyto cell functions. The multiplex protocol, Histoprofile®- T-reg light panel, developed at Cerba Research on the Discovery ULTRA (Ventana) platform is designed to stain specific sub-populations of T cells on a single slide, avoiding the need of serial sections from precious patient’s FFPE samples in clinical trials while still providing an indepth analysis of the tumor microenvironment.

Our in-depth analytical validation ensures the quality of this robust protocol on solid tumor tissues. Evaluate T-cell subpopulations and their spatial distribution in the tumor microenvironment.

Immune checkpoint proteins are important regulators in self-tolerance but also allow cancer cells to evade immune destruction. Checkpoint inhibitor (CKI) blockade therapies can help restore antitumoral immunity. Combination blockade has demonstrated the potential to result in greater tumor growth inhibition than monotherapies in preclinical studies.

Multiplex immunofluorescence offers a technical advantage by allowing for the detection of co-expression and spatial organization of multiple targets within a preserved tissue architecture on a single slide. We have developed the HISTOPROFILE®-CKI multiplex immunohistochemistry panel to offer personalized immune cell checkpoint profiling.

In a meta-analysis of several studies using various methodologies, worldwide prevalence of NAFLD (Non-alcoholic fatty liver disease) is 25.2% and 6.45% for NASH (Non-Alcoholic SteatoHepatitis). NASH prevalence is expected to increase by 63% between 2015 and 2030, yet the condition is still poorly understood and there is no known treatment. The need for therapeutic agents is urgent.

At Cerba Research, we are committed to improving the diagnosis and treatment for NASH. In 2016, after we successfully supported their Phase II NASH study, a midsize biotech engaged our services for Phase III. Gratified to have gained their trust and eager to continue our productive collaboration with this meticulous client, we rolled up our sleeves and took on the challenge of supporting the largest NASH Phase III study to date.
