Despite lower virulence, the omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) still poses a relevant threat for immunocompromised patients. A retrospective multicentric study was conducted to evaluate the efficacy of pre-exposure prophylaxis with tixagevimab/cilgavimab (Evusheld) with a 6-month follow-up for preventing severe COVID-19 in adult patients with hematology malignancy. Among the 606 patients in the cohort, 96 (16%) contracted COVID-19 with a median of 98.5 days after Evusheld administration. A total of 75% of patients had asymptomatic or mild severity of COVID-19, while just 25% of patients with SARS-CoV-2 positivity had to be hospitalized. Two patients (2%) died directly, and one patient (1%) in association with COVID-19. Eight patients (1.3%) of every cohort experienced adverse events related to Evusheld, mostly grade 1 and of reversible character. It was found that complete vaccination status or positive seroconversion was not associated with lower risk of COVID-19 infection. Previous treatment with an anti-CD20 monoclonal antibody was associated with higher rates of COVID-19, while previous treatment with anti-CD38 monoclonal antibody was not, as was the case for recipients of hematopoietic stem cell transplantation or CAR-T cell therapy. Presence of other comorbidities was not associated with more severe COVID-19. The results support the growing evidence for Evusheld's efficacy against severe COVID-19 in patients with hematology malignancies.

AIM: The aim of this study was to analyse the outcomes of patients with large B-cell lymphoma (LBCL) treated with chimeric antigen receptor T-cell therapy (CAR-Tx), with a focus on outcomes after CAR T-cell failure, and to define the risk factors for rapid progression and further treatment. METHODS: We analysed 107 patients with LBCL from the Czech Republic and Slovakia who were treated in ≥3rd-line with tisagenlecleucel or axicabtagene ciloleucel between 2019 and 2022. RESULTS: The overall response rate (ORR) was 60%, with a 50% complete response (CR) rate. The median progression-free survival (PFS) and overall survival (OS) were 4.3 and 26.4 months, respectively. Sixty-three patients (59%) were refractory or relapsed after CAR-Tx. Of these patients, 39 received radiotherapy or systemic therapy, with an ORR of 22% (CR 8%). The median follow-up of surviving patients in whom treatment failed was 10.6 months. Several factors predicting further treatment administration and outcomes were present even before CAR-Tx. Risk factors for not receiving further therapy after CAR-Tx failure were high lactate dehydrogenase (LDH) levels before apheresis, extranodal involvement (EN), high ferritin levels before lymphodepletion (LD) and ECOG PS >1 at R/P. The median OS-2 (from R/P after CAR-Tx) was 6.7 months (6-month 57.9%) for treated patients and 0.4 months (6-month 4.2%) for untreated patients (p < 0.001). The median PFS-2 (from R/P after CAR-Tx) was 3.2 months (6-month 28.5%) for treated patients. The risk factors for a shorter PFS-2 (n = 39) included: CRP > limit of the normal range (LNR) before LD, albumin < LNR and ECOG PS > 1 at R/P. All these factors, together with LDH > LNR before LD and EN involvement at R/P, predicted OS-2 for treated patients. CONCLUSION: Our findings allow better stratification of CAR-Tx candidates and stress the need for a proactive approach (earlier restaging, intervention after partial remission achievement).

Autoimunitní hemolytická anemie (AIHA) se vyskytuje u 5–11 % pacientů s chronickou lymfocytární leukemií (CLL). Akalabrutinib je selektivní kovalentní inhibitor Brutonovy tyrosinkinázy (BTKi), který je schválen pro léčbu CLL s mutací TP53 nebo del(17p) a v indikaci relabované/refrakterní CLL. Tato kazuistika popisuje léčbu časně relabující CLL s nutností léčby AIHA po kortikoterapii a imunochemoterapii, u které byl aplikován akalabrutinib. Na léčbě akalabrutinibem bylo dosaženo parciální remise CLL a AIHA se dostala pod kontrolu. Dávky kortikosteroidů bylo možné snížit a vysadit jeden měsíc od nasazení akalabrutinibu. V průběhu léčby akalabrutinibem nedošlo k reaktivaci AIHA. Kazuistika potvrzuje účinné a bezpečné podání akalabrutinibu u relabované aktivní CLL s AIHA, u které bylo nutné zahájit léčbu.
Autoimmune hemolytic anemia (AIHA) occurs in 5–11% of patients with chronic lymphocytic leukemia (CLL). Acalabrutinib is a selective, covalent Bruton tyrosinekinase inhibitor (BTKi) approved for the treatment of CLL with TP53 mutation or del(17p) and in relapsed/refractory CLL. This case report describes early relapsing CLL with treatment-emergent AIHA after steroids and immunochemotherapy that subsequently received acalabrutinib. The patient achieved a partial remission of CLL on acalabrutinib with controlled AIHA. Steroids were tapered off one month after the initiation of acalabrutinib as AIHA improved. No AIHA flare was documented on acalabrutinib. This case report confirms effective and safe application of acalabrutinib in a relapsed active CLL with treatment-emergent AIHA.

Ibrutinib revolutionized therapy for relapsed/refractory (R/R) mantle cell lymphoma (MCL). Real-world data on the outcome of unselected patients are still limited. We analyzed 77 R/R MCL patients receiving ibrutinib with at least one prior systemic anti-lymphoma therapy. After a median follow-up of 14.0 months, 56 patients relapsed/progressed, and 45 died. The overall response rate was 66%, with 31% of complete metabolic remissions on PET/CT. The median progression-free and overall survival (OS) rates were 10.3 and 23.1 months, respectively. The median OS from ibrutinib failure was 3.7 months. High proliferation rate by Ki67 (≥ 30%) and two or more previous therapy lines both negatively correlated with outcome (HR = 2.2, p = 0.04, and HR = 2.06, p = 0.08, respectively). Female gender borderline correlated with better outcome (HR = 0.53, p = 0.08). In multivariate analysis, Ki67 and response to ibrutinib both correlated with OS (p < 0.05). Importantly, ibrutinib appeared to better control nodal and extranodal lymphoma than bone marrow (BM) involvement. From 20 patients with detectable BM infiltration (before ibrutinib initiation) achieving complete (n = 13) or partial (n = 7) metabolic remission, none achieved remission in BM. We confirmed good efficacy of ibrutinib in unselected heavily pre-treated MCL patients. Our findings support the use of a combination of ibrutinib and rituximab in patients with BM involvement.

Výsledky klinické studie AETHERA ukázaly, že konsolidační terapie brentuximab vedotinem po vysokodávkované chemoterapii a provedení autologní transplantace kmenových hematopoetických buněk signifikantně prodlužuje přežití bez progrese u pacientů s klasickým Hodgkinovým lymfomem. V této multicentrické retrospektivní analýze sedmi hematologických center České republiky jsme analyzovali klinická data z reálné klinické praxe a výsledky léčby u 39 pacientů léčených konsolidační terapií brentuximab vedotinem od ledna 2015 do prosince 2021. Brentuximab vedotin nebyl nemocným podáván v předchozí léčbě lymfomu a pacienti měli nejméně jeden definovaný rizikový faktor pro další relaps. Medián podaných cyklů brentuximab vedotinu byl 8 (1-16), 82 % pacientů dosáhlo během léčby kompletní remise. Medián sledování byl 28 měsíců, dvouleté přežití bez progrese bylo 66,2 % (95% CI 0,52-0,85) a dvouleté celkové přežití 95 % (95% CI 0,82-1,00). Nejčastějším důvodem ukončení léčby bylo kompletní podání 16 léčebných cyklů (20,5 %), relaps/progrese lymfomu (15,4 %) a stejně tak rozvoj symptomatické periferní neuropatie, která byla v různém stupni závažnosti pozorována u 38,5 % pacientů. Naše data potvrzují deklarovanou účinnost a bezpečnost konsolidační terapie brentuximab vedotinem v reálné klinické praxi.
The results from the clinical trial AETHERA showed that consolidation therapy with brentuximab vedotin after high-dose chemotherapy followed by autologous stem cell transplantation increases progression free survival in high-risk patients with relapsed/refractory classic Hodgkin lymphoma. In this multicenter retrospective analysis from seven hematological centers in the Czech republic we have analysed real-life data of 39 patients treated between January 2015 and December 2021. Brentuximab vedotin was not administered in the previous treatment and the patients were at increased risk of subsequent lymphoma relapse with at least one defined risk factor. The median cycles of brentuximab vedotin administered was 8 (1-16), 82 % of the patients achieved complete remission during the treatment. The median follow-up was 28 months, the 2-year progression-free survival and overal survival were 66,2 % (95 % CI 0,52-0,85) and 95 % (95 % CI 0,82-1,00), respectively. The most common reason for treatment discontinuation was completion of 16 cycles administered (20,5 %) relapse/progression of the lymphoma (15,4 %) and symptomatic peripheral neuropathy as well, that was observed in various severity grades in 38,5 % patients overall. Our data have confirmed efficacy and safety of brentuximab vedotin consolidation therapy in the real-life clinical practice.

Patients with chronic lymphocytic leukemia (CLL) have a high risk of poor outcomes related to coronavirus disease 2019 (COVID-19). This multicenter cohort study evaluated the impact of COVID-19 infection on the population of CLL patients in the Czech Republic. Between March 2020 and May 2021, 341 patients (237 males) with CLL and COVID-19 disease were identified. The median age was 69 years (range 38-91). Out of the 214 (63%) patients with the history of therapy for CLL, 97 (45%) were receiving CLL-directed treatment at diagnosis of COVID-19: 29% Bruton tyrosine kinase inhibitor (BTKi), 16% chemoimmunotherapy (CIT), 11% Bcl-2 inhibitor, and 4% phosphoinositide 3-kinase inhibitor. Regarding the severity of COVID-19, 60% pts required admission to the hospital, 21% pts were admitted to the intensive care unit (ICU), and 12% received invasive mechanical ventilation. The overall case fatality rate was 28%. Major comorbidities, age over 72, male gender, CLL treatment in history, CLL-directed treatment at COVID-19 diagnosis were associated with increased risk of death. Of note, concurrent therapy with BTKi compared to CIT was not associated with better outcome of COVID-19.
