BACKGROUND In patients with melanoma, ipilimumab (an antibody against cytotoxic T-lymphocyte-associated antigen 4 [CTLA-4]) prolongs overall survival, and nivolumab (an antibody against the programmed death 1 [PD-1] receptor) produced durable tumor regression in a phase 1 trial. On the basis of their distinct immunologic mechanisms of action and supportive(More)
BACKGROUND Preclinical studies suggest that Reed-Sternberg cells exploit the programmed death 1 (PD-1) pathway to evade immune detection. In classic Hodgkin's lymphoma, alterations in chromosome 9p24.1 increase the abundance of the PD-1 ligands, PD-L1 and PD-L2, and promote their induction through Janus kinase (JAK)-signal transducer and activator of(More)
BACKGROUND Dermatologic adverse events (AEs) are some of the most frequently observed toxicities of immune-checkpoint inhibitor therapy, but they have received little attention. The drugs, pembrolizumab and nivolumab are recently approved inhibitors of the programmed death (PD)-1 receptor that have overlapping AE profiles however, the incidence, relative(More)
The abscopal effect is a phenomenon in which local radiotherapy is associated with the regression of metastatic cancer at a distance from the irradiated site. The abscopal effect may be mediated by activation of the immune system. Ipilimumab is a monoclonal antibody that inhibits an immunologic checkpoint on T cells, cytotoxic T-lymphocyte-associated(More)
Dominant Ellipse mutant alleles of the Drosophila EGF receptor homologue (DER) dramatically suppress ommatidium development in the eye and induce ectopic vein development in the wing. Their phenotype suggests a possible role for DER in specifying the founder R8 photoreceptor cells for each ommatidium. Here we analyze the basis of Ellipse mutations and use(More)
Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of cells that accumulate during tumor formation, facilitate immune escape, and enable tumor progression. MDSCs are important contributors to the development of an immunosuppressive tumor microenvironment that blocks the action of cytotoxic antitumor T effector cells. Heterogeneity in(More)
Standard carfilzomib (20 mg/m(2) cycle 1, 27 mg/m(2) thereafter; 2- to 10-minute infusion) is safe and effective in relapsed or refractory multiple myeloma (R/RMM). We report phase 2 results of carfilzomib 20 mg/m(2) on days 1 to 2 of cycle 1, 56 mg/m(2) thereafter (30-minute infusion), in R/RMM with the option of adding dexamethasone (20 mg) for suboptimal(More)
We aimed to identify whether the use of autologous hematopoietic cell transplantation (HCT) impacts outcomes for multiple myeloma patients with gains of chromosome 1q (+1q). We retrospectively identified 95 patients, 21% having +1q. For patients with +1q, the overall response rate to induction was 85%, with 40% having ≥ VGPR and 20% achieving a CR, similar(More)
Harnessing the adaptive immune response to treat malignancy is now a clinical reality. Several strategies are used to treat melanoma; however, very few result in a complete response. CD4(+) T cells are important and potent mediators of anti-tumor immunity and adoptive transfer of specific CD4(+) T cells can promote tumor regression in mice and patients.(More)
Tumor indoleamine 2,3-dioxygenase (IDO) promotes immunosuppression by direct action on effector T cells and Tregs and through recruitment, expansion and activation of myeloid-derived suppressor cells (MDSCs). Targeting of MDSCs is clinically being explored as a therapeutic strategy, though optimal targeting strategies and biomarkers predictive of response(More)
