Flt3 ligand augments immune responses to anti-DEC-205-NY-ESO-1 vaccine through expansion of dendritic cell subsets.

Generating responses to tumor antigens poses a challenge for immunotherapy. This phase II trial (NCT02129075) tested fms-like tyrosine kinase 3 (Flt3) ligand pre-treatment enhancement of responses to dendritic cell (DC)-targeting vaccines. We evaluated a regimen of Flt3L (CDX-301) to increase DCs and other antigen-presenting cells, poly-ICLC (TLR3 agonist that activates DCs) and a vaccine comprising anti-DEC-205-NY-ESO-1, a fusion antibody targeting CD205, linked to NY-ESO-1.

Examination of Patient-Reported Outcomes in Association with TNF-Inhibitor Treatment Response: Results from a US Observational Cohort Study.

Introduction: Implementation of a treat-to-target strategy is challenging when the patient and physician prioritize different goals. This study aimed to "translate" improvements in Clinical Disease Activity Index (CDAI) to concepts that resonate with patients (such as pain, fatigue, morning stiffness) by examining the association between changes in disease activity and patient-reported outcomes (PROs) in a national cohort of patients with rheumatoid arthritis (RA) initiating their first biologic treatment.

Methods: Patients in the Corrona registry with moderate or high disease activity (M/HDA) (defined by a CDAI score > 10), prior use of at least one conventional synthetic disease-modifying antirheumatic drug (csDMARD), 12-month follow-up, and initiating their first tumor necrosis factor inhibitor (TNFi) between 1 January 2006 through 1 November 2015 were identified.
