Updated Results from the German Mpnsg-0212 Combination Trial: Ruxolitinib Plus Pomalidomide in Myelofibrosis with Anemia
2019
Background: Anemia remains one cardinal symptom associated with reduced quality of life (QoL) in patients (pts) with myelofibrosis (MF) which is normally not being addressed by ruxolitinib (RUX). In our previous MPNSG-0109 trial, single-agent pomalidomide (POM) improved cytopenia in 14% (POM 0.5 mg QD) and 29% (POM 2.0 mg QD) of MF pts, respectively. In the MPNSG-0212 study, we sought to investigate the potential synergism of RUX plus POM to improve anemia and QoL in MF pts. Study Design: MPNSG-0212 is an ongoing multicenter, open-label, single-arm phase-Ib/II trial with a target population of 90 pts following a two-stage design (NCT01644110). Pts 1-40 in cohort 1 (co1) were treated with RU…
Catchup: a mouse model for imaging-based tracking and modulation of neutrophil granulocytes
2015
Neutrophil granulocyte biology is a central issue of immunological research, but the lack of animal models that allow for neutrophil-selective genetic manipulation has delayed progress. By modulating the neutrophil-specific locus Ly6G with a knock-in allele expressing Cre recombinase and the fluorescent protein tdTomato, we generated a mouse model termed Catchup that exhibits strong neutrophil specificity. Transgene activity was found only in very few eosinophils and basophils and was undetectable in bone marrow precursors, including granulomonocytic progenitors (GMPs). Cre-mediated reporter-gene activation allowed for intravital two-photon microscopy of neutrophils without adoptive transfe…
