NEW YORK and ANN ARBOR, Mich., April 7, 2015 /PRNewswire/ — Lycera Corp., a biopharmaceutical company developing breakthrough medicines to treat cancer and autoimmune disease, today announced that the Company will present preclinical research from its novel cancer immunotherapy program at the American Association of Immunologists (AAI) Annual Meeting, which will take place in New Orleans, Louisiana, May 8-12, 2015.

Specifics for the upcoming presentations at the AAI Annual Meeting are as follows:

“Novel RORγ Agonists Enhance Anti-Tumor Activity of Adoptive T Cell Therapy.” Oral Presentation Session: Cancer Immunotherapy and Mechanisms, Abstract Number 2207781, May 8, 3:45-4:00pm, Location: Room R04-R05. The findings also will be presented in a poster on May 9, 2:30-3:45pm, Location: Exhibit/Poster Hall.

Abbreviated Abstract Summary: As an approach to improve the potency and persistence of anti-tumor adoptive cell transfer (ACT) therapy, Lycera has designed synthetic RORγ agonists that can bolster the generation of type 17 cells. In vitro stimulation in the presence of RORγ agonists modulates expression of costimulatory and coinhibitory molecules and increases IL-17A, IL-22 and GM-CSF production while maintaining IFNγ production. Treating tumor-specific T cells with an RORγ agonist in vitro significantly enhanced the cells’ ability to regress large and established lymphoma and melanoma tumors in vivo. Further, ex vivo analysis showed that administration of RORγ agonist-treated T cells resulted in increased frequency of transferred cells, elevated IL-17A levels, and decreased PD-1 expression in tumors and spleen compared to controls.

The study authors concluded that by enhancing cytokine/chemokine production, promoting T cell persistence, as well as decreasing PD-1 expression, RORγ agonists provide an effective means to enhance the potency of adoptively transferred T cell products.
