Safety and tolerability of a 90-minute rapid infusion of Sandoz biosimilar rituximab in B-cell lymphoproliferative disorders in a real-world setting

Safety; B-cell lymphoproliferative disorders; Real-world settingSeguridad; Trastornos linfoproliferativos de células B; Entorno realSeguretat; Trastorns limfoproliferatius de cèl·lules B; Entorn realAlthough rituximab is generally well-tolerated, infusion-related reactions (IRRs) are common with the initial dose when administered intravenously according to standard recommendations. To prevent IRRs, premedication and low-speed infusion rates have been recommended. Consequently, intravenous (i.v.) infusion of rituximab can become a labor-intensive process. Rapid i.v. rituximab infusion over 90 min has demonstrated a favorable safety profile for the second and subsequent infusions during the course of therapy. The aim of this study was to investigate the safety and tolerability of 90-min rapid infusion of Sandoz rituximab biosimilar (SDZ-RTX) for patients with CD20+ lymphoma or chronic lymphocytic leukemia (CLL). We retrospectively reviewed all patients with CD20+ lymphoma or CLL who received SDZ-RTX infusions in 90 min from July 2019 to July 2021 at seven Spanish hospitals. The primary end point was the incidence of IRRs. We identified 124 patients and 576 rapid administrations of SDZ-RTX, with an average of five rapid infusions per patient. Most rapid infusions of SDZ-RTX were in combination with CHOP/CHOP-like therapy (48.4%), followed by SDZ-RTX alone (15.1%), in combination with bendamustine (14.5%), or with other regimens (22%). The 90-min SDZ-RTX infusion schedule was well-tolerated with no grade 3/4 IRRs. The incidence of any grade IRR during the first rapid infusion was 1% (5 grade 1 IRRs and 1 grade 2 IRR). In conclusion, rapid 90-min i.v. administration of SDZ-RTX for the second and subsequent infusions during the course of therapy is well-tolerated in patients with CD20+ lymphoma or CLL.This study was funded by Sandoz Group, a Novartis Division, as an investigator project in the GELTAMO group

Artificial intelligence and architectural design : an introduction

Descripció del recurs: 27 juliol 2022The aim of this book on artificial intelligence for architects and designers is to guide future designers, in general, and architects, in particular, to support the social and cultural wellbeing of the humanity in a digital and global environment. This objective is today essential but also extremely large, interdisciplinary and interartistic, so we have done just a brief introduction of the subject. We will start with the argument fixed by the Professor Jonas Langer in his web some years ago, that we have defined as: “The Langer’s Tree”.Primera edició

Early progression in follicular lymphoma in the absence of histological transformation or high-risk Follicular Lymphoma International Prognostic Index still has a favourable outcome

Although follicular lymphoma (FL) patients relapsing within 24 months after first-line treatment (POD24) have a poor prognosis, some cases show notable survival after first relapse (SF1R). We aimed to characterize the POD24 FL population and to identify the main prognostic factors at progression. We selected 162 POD24 patients (80F; median age at first relapse 59 years) from a cohort of 1067 grades 1-3a FL-treated patients. The remaining 905 patients treated with first-line immunochemotherapy and diagnosed during the same period were used to compare outcomes in terms of survival. After a median follow-up of 11.0 years, 96 patients died (10y-SF1R of 40%). Age over 60 years (p < 0.001), high lactate dehydrogenase (LDH) (p < 0.001), haemoglobin (Hb) less than 120 g/L (p < 0.001), advanced stage (p < 0.001), high-risk Follicular Lymphoma International Prognostic Index (FLIPI) (p < 0.001), histological transformation (HT) (p < 0.001) and reaching less than complete response (CR) after salvage therapy (p < 0.001), predicted poor SF1R at relapse. In multivariate analysis only high-risk FLIPI and HT maintained prognostic significance for SF1R. POD24 patients not transformed and with low/intermediate FLIPI at relapse behaved better than the remaining cases. POD24 patients showed an excess mortality of 38% compared to the general population. Although outcome of POD24 FL patients is poor, a considerable group of them (low/intermediate FLIPI and not transformed at first relapse) behave better

Ibrutinib in Combination With Rituximab for Indolent Clinical Forms of Mantle Cell Lymphoma (IMCL-2015): A Multicenter, Open-Label, Single-Arm, Phase II Trial

PURPOSE The need for an individualized management of indolent clinical forms in mantle cell lymphoma (MCL) is increasingly recognized. We hypothesized that a tailored treatment with ibrutinib in combination with rituximab (IR) could obtain significant responses in these patients. METHODS This is a multicenter single-arm, open-label, phase II study with a two-stage design conducted in 12 Spanish GELTAMO sites (ClinicalTrials.gov identifier: NCT02682641). Previously untreated MCL patients with indolent clinical forms defined by the following criteria were eligible: no disease-related symptoms, nonblastoid variants, Ki-67 < 30%, and largest tumor diameter <= 3 cm. Both leukemic non-nodal and nodal subtypes were recruited. Patients received ibrutinib 560 mg once daily and a total of eight doses of rituximab 375 mg/m(2). Ibrutinib could be discontinued after 2 years in the case of sustained undetectable minimal residual disease (MRD). The primary end point was the complete response (CR) rate achieved after 12 cycles according to Lugano criteria. RESULTS Fifty patients with MCL (male 66%; median age 65 years) were enrolled. After 12 cycles of treatment, 42 (84%; 95% CI, 74 to 94) patients had an overall response, including 40 (80%; 95% CI, 69 to 91) with CR. Moreover, undetectable MRD in peripheral blood was achieved in 87% (95% CI, 77 to 97) of cases. At 2 years, 24 of 35 evaluable patients (69%) could discontinue ibrutinib because of undetectable MRD. Four patients had disease progression; three were non-nodal MCL and carried high genomic complexity and TP53 mutations at enrollment. No unexpected toxicity was seen except one patient with severe aplastic anemia. CONCLUSION Frontline IR combination achieves a high rate of CRs and undetectable MRD in indolent clinical forms of MCL. Discontinuation seems appropriate in cases with undetectable MRD, except for TP53-mutated cases

Genetic and phenotypic characterisation of HIV-associated aggressive B-cell non-Hodgkin lymphomas, which do not occur specifically in this population: diagnostic and prognostic implications

The frequency of aggressive subtypes of B-cell non-Hodgkin lymphoma (B-NHL), such as high-grade B-cell lymphomas (HGBL) with MYC and BCL2 and/or BCL6 rearrangement (HGBL-DH/TH) or Burkitt-like lymphoma (BL) with 11q aberration, is not well known in the HIV setting. We aimed to characterise HIV-associated aggressive B-NHL according to the 2017 WHO criteria, and to identify genotypic and phenotypic features with prognostic impact. Seventy-five HIV-associated aggressive B-NHL were studied by immunohistochemistry (CD10, BCL2, BCL6, MUM1, MYC, and CD30), EBV-encoded RNAs (EBERs), and fluorescence in situ hybridisation (FISH) to evaluate the status of the MYC, BCL2, and BCL6 genes and chromosome 11q. The 2017 WHO classification criteria and the Hans algorithm, for the cell-of-origin classification of diffuse large B-cell lymphomas (DLBCL), were applied. In DLBCL cases, the frequencies of MYC and BCL6 rearrangements (14.9 and 27.7%, respectively) were similar to those described in HIV-negative patients, but BCL2 rearrangements were infrequent (4.3%). MYC expression was identified in 23.4% of DLBCL cases, and coexpression of MYC and BCL2 in 13.0%, which was associated with a worse prognosis. As for BL cases, the expression of MUM1 (30.4%) conferred a worse prognosis. Finally, the prevalence of HGBL-DH/TH and BL-like with 11q aberration are reported in the HIV setting. The phenotypic and genotypic characteristics of HIV-associated aggressive B-NHL are similar to those of the general population, except for the low frequency of BCL2 rearrangements in DLBCL. MYC and BCL2 coexpression in DLBCL, and MUM-1 expression in BL, have a negative prognostic impact on HIV-infected individuals.Peer reviewe
