Abstract B072: Phase Ib trial of the RNActive cancer vaccine BI 1361849 (CV9202) and local radiotherapy in patients with stage IV non-small cell lung cancer (NSCLC) with disease control after first-line chemotherapy or during therapy with an epidermal growth factor receptor tyrosine kinase inhibitor: Updated clinical results and immune responses
Abstract Background: Preclinical studies demonstrated that local radiotherapy (RT) acts synergistically with RNActive mRNA vaccines to enhance anti-tumor effects and increase tumor-infiltrating lymphocytes. BI 1361849 is a therapeutic vaccine comprising optimized mRNA constituents encoding six NSCLC-associated antigens. Interim data of a phase Ib study, employing local RT to increase the immune mediated tumor control by BI 1361849, have been previously published (J Clin Oncol 34, 2016, suppl; abstr e20627). Here we report results of immune response analyses as well as updated safety and efficacy data. Methods: Patients (pts) with stage IV NSCLC were enrolled in three cohorts based on histol…
Immunosenescence and Cytomegalovirus
Since Looney at al. published their seminal paper a decade ago [1] it has become clear that many of the differences in T cell immunological parameters observed between young and old people are related to the age-associated increasing prevalence of infection with the persistent β-herpesvirus HHV-5 (Cytomegalovirus). Ten years later, studies suggest that hallmark age-associated changes in peripheral blood T cell subset distribution may not occur at all in people who are not infected with this virus [[2]; Derhovanessian et al., in press]. Whether the observed changes are actually caused by CMV is an open question, but very similar, rapid changes observed in uninfected patients receiving CMV-in…
