In a phase 1b study, intravenous daratumumab plus pomalidomide and dexamethasone induced a very good partial response or better rate of 42% and was well tolerated in patients with heavily pretreated multiple myeloma. We aimed to evaluate whether daratumumab plus pomalidomide and dexamethasone would improve progression-free survival versus pomalidomide and dexamethasone alone in patients with previously treated multiple myeloma. In this ongoing, open-label, randomised, phase 3 trial (APOLLO) done at 48 academic centres and hospitals across 12 European countries, eligible patients were aged 18 years or older, had relapsed or refractory multiple myeloma with measurable disease, had an Eastern Cooperative Oncology Group performance status of 0–2, had at least one previous line of therapy, including lenalidomide and a proteasome inhibitor, had a partial response or better to one or more previous lines of antimyeloma therapy, and were refractory to lenalidomide if only one previous line of therapy was received. Patients were randomly assigned (1:1) by an interactive web-response system in a random block size of two or four to receive pomalidomide and dexamethasone alone or daratumumab plus pomalidomide and dexamethasone. Randomisation was stratified by number of previous lines of therapy and International Staging System disease stage. All patients received oral pomalidomide (4 mg, once daily on days 1–21) and oral dexamethasone (40 mg once daily on days 1, 8, 15, and 22; 20 mg for those aged 75 years or older) at each 28-day cycle. The daratumumab plus pomalidomide and dexamethasone group received daratumumab (1800 mg subcutaneously or 16 mg/kg intravenously) weekly during cycles 1 and 2, every 2 weeks during cycles 3–6, and every 4 weeks thereafter until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival in the intention-to-treat population. Safety was analysed in all patients who received at least one dose of study medication. This trial is registered with ClinicalTrials.gov, NCT03180736. Between June 22, 2017, and June 13, 2019, 304 patients (median age 67 years [IQR 60–72]; 161 [53%] men and 143 [47%] women) were randomly assigned to the daratumumab plus pomalidomide and dexamethasone group (n=151) or the pomalidomide and dexamethasone group (n=153). At a median follow-up of 16·9 months (IQR 14·4–20·6), the daratumumab plus pomalidomide and dexamethasone group showed improved progression-free survival compared with the pomalidomide and dexamethasone group (median 12·4 months [95% CI 8·3–19·3] vs 6·9 months [5·5–9·3]; hazard ratio 0·63 [95% CI 0·47–0·85], two-sided p=0·0018). The most common grade 3 or 4 adverse events were neutropenia (101 [68%] of 149 patients in the daratumumab plus pomalidomide and dexamethasone group vs 76 [51%] of 150 patients in the pomalidomide and dexamethasone group), anaemia (25 [17%] vs 32 [21%]), and thrombocytopenia (26 [17%] vs 27 [18%]). Serious adverse events occurred in 75 (50%) of 149 patients in the daratumumab plus pomalidomide and dexamethasone group versus 59 (39%) of 150 patients in the pomalidomide and dexamethasone group; pneumonia (23 [15%] vs 12 [8%] patients) and lower respiratory tract infection (18 [12%] vs 14 [9%]) were most common. Treatment-emergent deaths were reported in 11 (7%) patients in the daratumumab plus pomalidomide and dexamethasone group versus 11 (7%) patients in the pomalidomide and dexamethasone group. Among patients with relapsed or refractory multiple myeloma, daratumumab plus pomalidomide and dexamethasone reduced the risk of disease progression or death versus pomalidomide and dexamethasone alone and could be considered a new treatment option in this setting.

T-cell redirecting bispecific antibodies (BsAbs) and chimeric antigen receptor T cells (CAR T cells) have revolutionised multiple myeloma therapy, but adverse events such as cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome (ICANS), cytopenias, hypogammaglobulinaemia, and infections are common. This Policy Review presents a consensus from the European Myeloma Network on the prevention and management of these adverse events. Recommended measures include premedication, frequent assessing for symptoms and severity of cytokine release syndrome, step-up dosing for several BsAbs and some CAR T-cell therapies; corticosteroids; and tocilizumab in the case of cytokine release syndrome. Other anti-IL-6 drugs, high-dose corticosteroids, and anakinra might be considered in refractory cases. ICANS often arises concomitantly with cytokine release syndrome. Glucocorticosteroids in increasing doses are recommended if needed, as well as anakinra if the response is inadequate, and anticonvulsants if convulsions occur. Preventive measures against infections include antiviral and antibacterial drugs and administration of immunoglobulins. Treatment of infections and other complications is also addressed.

Background: Limited real-world data (RWD) may provide important information regarding diagnostic and treatment patterns in patients (pts) with AL Amyloidosis. The aim was to analyze the characteristics, treatment approach and clinical outcome of patients in the real-world settings. Materials and Methods: RWD of 60 pts diagnosed with AL amyloidosis were analyzed. Advanced cardiac involvement, Mayo Clinical Stage (CS) IIIa and IIIb, and Revised-Mayo CS III and IV, has been found in 26.7%, and 16.7%, or 33.3% and 16.7%, respectively. Bortezomib (Bz)-based regimens were applied in 36 pts (60%), and alkylating-based regimens in 24 pts (40%). In 8 pts (13.3%) treated initially with CyBorD induction, high-dose therapy with Melphalan and autologous stem cell transplantation (HDT + ASCT) was applied as the first line of treatment. Results: The overall response rate (ORR, ≥partial response) was achieved in 40 pts (70%). Patients treated with Bz-based induction followed by HDT + ASCT achieved significantly better hematologic (p = 0.001), cardiac (p = 0.004) and renal response rates (p = 0.002) in comparison to CyBorD or Alk-based regimens alone. There was no difference in PFS between those groups (p = 0.733), but patients treated with CyBorD + HDT + ASCT had significantly durable OS (p = 0.039). Univariate analysis pointed out the predictive influence of cardiac involvement (Mayo CS and Revised Mayo CS), ASCT eligibility, and hematologic, cardiac, renal and composite response rates. Conclusions: Advanced cardiac involvement and cardiac and hematologic response still retain adverse prognostic impact on the clinical outcome. Bz-based combinations significantly improved the survival of patients with AL amyloidosis, regardless of HDT + ASCT treatment.

The treatment of chronic lymphocytic leukemia (CLL) consists of the continuous use of Bruton tyrosine kinase inhibitors (BTKis) such as ibrutinib, acalabrutinib, zanubrutinib and pirtobrutinib, or Bcl-2 inhibitors, such as venetoclax. Overall survival (OS) and progression-free survival (PFS) of CLL patients are significantly improved with the use of these therapies. Adverse effects (AEs) that can occur during treatment and the presence of pre-existing comorbidities in patients can influence subsequent treatment outcomes and, consequently, OS and PFS. Managing these AEs, including cardiologic toxicity and infections (including fungal infections), as well as treating cardiovascular and other comorbidities, can be challenging due to potential drug interactions with the medications used for the management of AEs and comorbidities. Therefore, this review examined the key challenges associated with the concomitant use of novel CLL therapies and medications for managing comorbidities and AEs. This review aims to enhance and facilitate the management of patients with CLL.

Immune reconstitution (IR) after allogeneic stem cell transplantation has been highlighted as pivotal in achieving favorable long-term outcomes by influencing the rates of infection, graft versus host disease (GvHD) and relapse. However, data on the impact of different lymphocyte subsets influencing outcomes is conflicting. Furthermore, the importance of immune reconstitution parameters in patients previously not experiencing major post-transplant complications is lacking. We evaluated the clinical impact of day 90 NK cell, CD4 T-cell, CD8 T-cell, B-cell, and NKT cell counts on transplant outcomes by performing a landmark analysis in event-free patients. Lymphocyte subset counts were obtained from 70 patients undergoing in vivo T-cell depleted allogeneic transplantation from 2018 to 2024. Patients eligible for the study experienced no acute GvHD, poor graft function, graft failure, or relapse in the first three months after transplantation-prior to obtaining IR data. We associated lymphocyte subset counts to overall survival (OS), non-relapse mortality (NRM), cumulative incidence of relapse (RI), and secondary graft failure/poor graft function. High NK cell counts on day 90 (>178/μL) were associated with improved OS (P=0.039) and lower rates of NRM (1-year cumulative incidence of 5.7% versus 31.4%, HR 0.16, 95% CI 0.04-0.69, P=0.014). A protective effect on RI was not found. We found no patient, disease or transplant-related variables to be significantly associated with day 90 NK cell counts. The results suggest that high NK cell counts on day 90 after T-cell depleted allogeneic transplantation independently protect from NRM and improve OS in patients without prior major post-transplant complications.

IntroductionVitamin D has a role in cellular differentiation, proliferation, apoptosis, and angiogenesis and therefore is studied as a prognostic factor in cancer. The aim of our study was to assess the prevalence and significance of 25(OH)D deficiency in patients with lymphoid malignancies.MethodologyBetween January 2014 and June 2016 at the Clinic for Hematology, Clinical Center of Serbia, Belgrade, the pretreatment serum level of 25(OH)D was determined in 133 (62 women/71 men, median age 58 (18–84) years) previously untreated patients with lymphoid malignancy using a chemiluminescent immunoassay. From their medical records, we noted the age, clinical stage, Eastern Cooperative Oncology Group Performance Scale (ECOG PS), nutritional status using the Nutritional Risk Score 2002 (NRS2002), the time of year, comorbidity index, progression, and progression-free survival (PFS) for a median of 20 (1–32) months. The optimal cutoff point for prediction of outcome was determined using the Maximally Selected Rank Statistics.ResultsThere were 37 (27.8%) patients with the severe 25(OH)D deficiency ≤ 25 nmol/l, 80 (60.2%) with 25(OH)D deficiency 25–50 nmol/l, and 16 (12%) with 25(OH)D insufficiency 50–75 nmol/l. None of the patients had the desired normal level. There were significant differences between groups in regard to ECOG PS, NRS2002, type of lymphoma, and progression. The severely 25(OH)D-deficient patients had a shorter mean time until progression (P = 0.018). Cox regression analysis showed that 25(OH)D < 19.6 nmol/l remained the only significant parameter for PFS (HR = 2.921; 95% CI 1.307–6.529).ConclusionThe prevalence of 25(OH)D deficiency in the analyzed group of patients with lymphoid malignancies is high and greater in malnourished individuals. Patients with pretreatment serum 25(OH)D < 19.6 nmol/l had a significantly shorter PFS.

The Follicular Lymphoma International Prognostic Index (FLIPI) is widely used in the identification of risk groups among follicular lymphoma (FL) patients. The aim of the present study was to evaluate the prognostic value of FLIPI combined with the Charlson comorbidity index (CCI) and histological grade of lymphoma. 224 newly diagnosed FL patients (median age 56 years) treated with immunochemotherapy were retrospectively analysed. Low FLIPI had 21.0 % of patients, intermediate 28.1 % and high 46.9 %. 50.9 % of patients had no comorbidities. Only 7.1 % of patients had a high CCI score (≥2), while 25.9 % of patients were histological grade 3. Parameters that influenced overall survival were evaluated using Cox regression analysis, in which CCI, FLIPI and histological grade ( p  < 0.05) retained prognostic significance. By combining these parameters, we have developed the FCG score, which incorporates FLIPI, CCI, and histological grade. This score defines three risk categories (low: 41.5 %; intermediate: 37.5 %; high: 13.4 %), associated with significantly different survival ( p  < 0.0001); this consequently improves discriminative power by 9.1 % compared to FLIPI. FCG score represents a possible new prognostic index, highlighting the role of the patient’s clinical state and the histological characteristics of disease, as indicated by comorbidity index and histological grade of lymphoma.

The presence of multiple myeloma (MM) in a patient with systemic sclerosis is a rare and unusual occurrence with unclear significance. We report the case of a 55-year-old woman with a 20-year history of systemic sclerosis, who subsequently presented with clinical stage IIIA IgG-λ MM. The systemic sclerosis was diagnosed and treated in 1988 with d -penicillamine and methotrexate. Twenty years later, in December 2008, she presented with symptoms of Raynaud’s phenomenon and intense facial pruritus. Immunoelectrophoresis confirmed the presence of a IgG-λ paraprotein (71.90 g/l) and Bence Jones proteinuria of the lambda light chains. Bone marrow histology revealed infiltrates of plasmocytes and lymphoplasmocytes which were on immunohistochemistry CD38+, FGF-R3+ and OPG+. An extensive X-ray skeletal survey did not show any osteolytic lesions or fractures. The patient was treated according to the CTD protocol (cyclophosphamide, thalidomide, and dexamethasone) which was effective against the myeloma as well as the systemic sclerosis and patient achieved complete remission.

Selinexor combined with dexamethasone has shown activity in patients with heavily pre-treated multiple myeloma. In a phase 1b/2 study, the combination of oral selinexor with bortezomib (a proteasome inhibitor) and dexamethasone induced high response rates with low rates of peripheral neuropathy, the main dose-limiting toxicity of bortezomib. We aimed to evaluate the clinical benefit of weekly selinexor, bortezomib, and dexamethasone versus standard bortezomib and dexamethasone in patients with previously treated multiple myeloma. This phase 3, randomised, open-label trial was done at 123 sites in 21 countries. Patients aged 18 years or older, who had multiple myeloma, and who had previously been treated with one to three lines of therapy, including proteasome inhibitors, were randomly allocated (1:1) to receive selinexor (100 mg once per week), bortezomib (1·3 mg/m2 once per week), and dexamethasone (20 mg twice per week), or bortezomib (1·3 mg/m2 twice per week for the first 24 weeks and once per week thereafter) and dexamethasone (20 mg four times per week for the first 24 weeks and twice per week thereafter). Randomisation was done using interactive response technology and stratified by previous proteasome inhibitor therapy, lines of treatment, and multiple myeloma stage. The primary endpoint was progression-free survival in the intention-to-treat population. Patients who received at least one dose of study treatment were included in the safety population. This trial is registered at ClinicalTrials.gov, NCT03110562. The trial is ongoing, with 55 patients remaining on randomised therapy as of Feb 20, 2020. Of 457 patients screened for eligibility, 402 were randomly allocated—195 (49%) to the selinexor, bortezomib, and dexamethasone group and 207 (51%) to the bortezomib and dexamethasone group—and the first dose of study medication was given between June 6, 2017, and Feb 5, 2019. Median follow-up durations were 13·2 months [IQR 6·2–19·8] for the selinexor, bortezomib, and dexamethasone group and 16·5 months [9·4–19·8] for the bortezomib and dexamethasone group. Median progression-free survival was 13·93 months (95% CI 11·73–not evaluable) with selinexor, bortezomib, and dexamethasone and 9·46 months (8·11–10·78) with bortezomib and dexamethasone (hazard ratio 0·70 [95% CI 0·53–0·93], p=0·0075). The most frequent grade 3–4 adverse events were thrombocytopenia (77 [39%] of 195 patients in the selinexor, bortezomib, and dexamethasone group vs 35 [17%] of 204 in the bortezomib and dexamethasone group), fatigue (26 [13%] vs two [1%]), anaemia (31 [16%] vs 20 [10%]), and pneumonia (22 [11%] vs 22 [11%]). Peripheral neuropathy of grade 2 or above was less frequent with selinexor, bortezomib, and dexamethasone (41 [21%] patients) than with bortezomib and dexamethasone (70 [34%] patients; odds ratio 0·50 [95% CI 0·32–0·79], p=0·0013). 47 (24%) patients in the selinexor, bortezomib, and dexamethasone group and 62 (30%) in the bortezomib and dexamethasone group died. A once-per-week regimen of selinexor, bortezomib, and dexamethasone is a novel, effective, and convenient treatment option for patients with multiple myeloma who have received one to three previous lines of therapy.
