Treatment of retroperitoneal fibrosis with rituximab, cyclophosphamide and dexamethasone, followed by rituximab and dexamethasone maintenance, achieved disappearance of pathological PET accumulation of FDG and regression of fibrotic masses after 4 months….

Background: Idiopathic retroperitoneal fibrosis is characterized by the development of inflammatory infiltrates with marked fibrosis along the large retroperitoneal vessels. Rituximab in combination with glucocorticoids constitute an effective therapy, but the responses are not long-lasting. In other similar situations, addition of cyclophosphamide to the combination achieved longer and deeper responses.

A phase 1b/2 study evaluating efficacy and safety of MP0250, a designed ankyrin repeat protein (DARPin) simultaneously targeting vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF), in combination with bortezomib and dexamethasone, in patients with relapsed or refractory multiple myeloma.

MP0250 is a designed ankyrin repeat protein that specifically inhibits both vascular endothelial growth factor A (VEGF-A) and hepatocyte growth factor (HGF), aiming at potentiating cancer therapy by disrupting the tumour microenvironment. Encouraging results from a phase 1 trial of MP0250 in patients with solid tumours prompted further investigation in multiple myeloma (MM) as both MP0250 targets are reported to be drivers of MM pathogenesis. In this open-label, single-arm phase 1b/2 study (NCT03136653) in patients with proteasome inhibitor- and/or immunomodulatory drug-relapsed or refractory MM, MP0250 was administered every 3 weeks with standard bortezomib/dexamethasone regimen.

Real-World Evidence on Prognostic Value of MRD in Multiple Myeloma Using Flow Cytometry.

Minimal residual disease (MRD) is one of the most important prognostic factors in multiple myeloma (MM) and a valid surrogate for progression-free survival (PFS) and overall survival (OS). Recently, MRD negativity was approved as an early clinical endpoint for accelerated drug approval in MM. Nevertheless, there is limited evidence of MRD utility in real-world setting.

Efficacy of ixazomib, lenalidomide, dexamethasone regimen in daratumumab-exposed relapsed/refractory multiple myeloma patients: A retrospective analysis.

We performed retrospective analysis of relapsed/refractory multiple myeloma (RRMM) patients previously exposed to daratumumab treated with ixazomib, lenalidomide, dexamethasone (IRd) regimen in real clinical practice. Our aim was to evaluate efficacy of IRd in these patients and select a subset of patients that would benefit from this treatment the most. In total, we analyzed 43 daratumumab-exposed RRMM patients treated in our center.
