The addition of subcutaneous daratumumab to bortezomib, lenalidomide, and dexamethasone therapy and to lenalidomide maintenance therapy had a significant benefit on progression-free survival among patients with multiple myeloma.

Among hospitalized patients with Covid-19, treatment with dexamethasone resulted in lower 28-day mortality than usual care, according to the level of respiratory support the patients were receiving, indicating a possible correlation between efficacy and the stage of infection.

Bortezomib, lenalidomide, and dexamethasone (VRd) is a preferred first-line treatment option for patients with newly diagnosed multiple myeloma. Whether the addition of the anti-CD38 monoclonal antibody isatuximab to the VRd regimen would reduce the risk of disease progression or death among patients ineligible to undergo transplantation is unclear. In an international, open-label, phase 3 trial, we randomly assigned, in a 3:2 ratio, patients 18 to 80 years of age with newly diagnosed multiple myeloma who were ineligible to undergo transplantation to receive either isatuximab plus VRd or VRd alone. The primary efficacy end point was progression-free survival. Key secondary end points included a complete response or better and minimal residual disease (MRD)-negative status in patients with a complete response. A total of 446 patients underwent randomization. At a median follow-up of 59.7 months, the estimated progression-free survival at 60 months was 63.2% in the isatuximab-VRd group, as compared with 45.2% in the VRd group (hazard ratio for disease progression or death, 0.60; 98.5% confidence interval, 0.41 to 0.88; P<0.001). The percentage of patients with a complete response or better was significantly higher in the isatuximab-VRd group than in the VRd group (74.7% vs. 64.1%, P = 0.01), as was the percentage of patients with MRD-negative status and a complete response (55.5% vs. 40.9%, P = 0.003). No new safety signals were observed with the isatuximab-VRd regimen. The incidence of serious adverse events during treatment and the incidence of adverse events leading to discontinuation were similar in the two groups. Isatuximab-VRd was more effective than VRd as initial therapy in patients 18 to 80 years of age with newly diagnosed multiple myeloma who were ineligible to undergo transplantation.

The addition of daratumumab to lenalinomide and dexamethasone in patients with previously untreated myeloma who were not eligible for high-dose chemotherapy and hematopoietic stem-cell transplantation resulted in a higher response rate, an increased depth of response, and longer progression-free survival than lenalidomide and dexamethasone alone.

Intensified systemic chemotherapy has the highest primary cure rate for advanced-stage, classical Hodgkin lymphoma but this comes with a cost of severe and potentially life long, persisting toxicities. With the new regimen of brentuximab vedotin, etoposide, cyclophosphamide, doxorubicin, dacarbazine, and dexamethasone (BrECADD), we aimed to improve the risk-to-benefit ratio of treatment of advanced-stage, classical Hodgkin lymphoma guided by PET after two cycles. This randomised, multicentre, parallel, open-label, phase 3 trial was done in 233 trial sites across nine countries. Eligible patients were adults (aged ≤60 years) with newly diagnosed, advanced-stage, classical Hodgkin lymphoma (ie, Ann Arbor stage III/IV, stage II with B symptoms, and either one or both risk factors of large mediastinal mass and extranodal lesions). Patients were randomly assigned (1:1) to four or six cycles (21-day intervals) of escalated doses of etoposide (200 mg/m2 intravenously on days 1–3), doxorubicin (35 mg/m2 intravenously on day 1), and cyclophosphamide (1250 mg/m2 intravenously on day 1), and standard doses of bleomycin (10 mg/m2 intravenously on day 8), vincristine (1·4 mg/m2 intravenously on day 8), procarbazine (100 mg/m2 orally on days 1–7), and prednisone (40 mg/m2 orally on days 1–14; eBEACOPP) or BrECADD, guided by PET after two cycles. Patients and investigators were not masked to treatment assignment. Hierarchical coprimary objectives were to show (1) improved tolerability defined by treatment-related morbidity and (2) non-inferior efficacy defined by progression-free survival with an absolute non-inferiority margin of 6 percentage points of BrECADD compared with eBEACOPP. An additional test of superiority of progression-free survival was to be done if non-inferiority had been established. Analyses were done by intention to treat; the treatment-related morbidity assessment required documentation of at least one chemotherapy cycle. This trial was registered at ClinicalTrials.gov (NCT02661503). Between July 22, 2016, and Aug 27, 2020, 1500 patients were enrolled, of whom 749 were randomly assigned to BrECADD and 751 to eBEACOPP. 1482 patients were included in the intention-to-treat analysis. The median age of patients was 31 years (IQR 24–42). 838 (56%) of 1482 patients were male and 644 (44%) were female. Most patients were White (1352 [91%] of 1482). Treatment-related morbidity was significantly lower with BrECADD (312 [42%] of 738 patients) than with eBEACOPP (430 [59%] of 732 patients; relative risk 0·72 [95% CI 0·65–0·80]; p<0·0001). At a median follow-up of 48 months, BrECADD improved progression-free survival with a hazard ratio of 0·66 (0·45–0·97; p=0·035); 4-year progression-free survival estimates were 94·3% (95% CI 92·6–96·1) for BrECADD and 90·9% (88·7–93·1) for eBEACOPP. 4-year overall survival rates were 98·6% (97·7–99·5) and 98·2% (97·2–99·3), respectively. BrECADD guided by PET after two cycles is better tolerated and more effective than eBEACOPP in first-line treatment of adult patients with advanced-stage, classical Hodgkin lymphoma.

In a large, multinational, randomized trial, continuous lenalidomide maintenance therapy after triplet therapy (lenalidomide, bortezomib, and dexamethasone) and autologous stem-cell transplantation resulted in longer progression-free survival than triplet therapy alone.

Venetoclax is a highly selective, potent, oral BCL-2 inhibitor, which induces apoptosis in multiple myeloma cells. Venetoclax plus bortezomib and dexamethasone has shown encouraging clinical efficacy with acceptable safety and tolerability in a phase 1 trial. The aim of this study was to evaluate venetoclax plus bortezomib and dexamethasone in patients with relapsed or refractory multiple myeloma. In this randomised, double-blind, multicentre, phase 3 trial, patients aged 18 years or older with relapsed or refractory multiple myeloma, an Eastern Cooperative Oncology Group performance status of 2 or less, who had received one to three previous therapies were enrolled from 90 hospitals in 16 countries. Eligible patients were randomly assigned (2:1) centrally using an interactive response technology system and a block size of three to receive venetoclax (800 mg per day orally) or placebo with bortezomib (1·3 mg/m2 subcutaneously or intravenously and dexamethasone (20 mg orally). Treatment was given in 21-day cycles for the first eight cycles and 35-day cycles from the ninth cycle until disease progression, unacceptable toxicity, or patient withdrawal. Randomisation was stratified by previous exposure to a proteasome inhibitor and the number of previous therapies. Sponsors, investigators, study site personnel, and patients were masked to the treatment allocation throughout the study. The primary endpoint was independent review committee-assessed progression-free survival in the intention-to-treat population. Safety analyses were done in patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, NCT02755597. Between July 19, 2016, and Oct 31, 2017, 291 patients were randomly assigned to receive venetoclax (n=194) or placebo (n=97). With a median follow-up of 18·7 months (IQR 16·6–21·0), median progression-free survival according to independent review committee was 22·4 months (95% CI 15·3–not estimable) with venetoclax versus 11·5 months (9·6–15·0) with placebo (hazard ratio [HR] 0·63 [95% CI 0·44–0·90]; p=0·010). The most common grade 3 or worse treatment-emergent adverse events were neutropenia (35 [18%] of 193 patients in the venetoclax group vs seven [7%] of 96 patients in the placebo group), pneumonia (30 [16%] vs nine [9%]), thrombocytopenia (28 [15%] vs 29 [30%]), anaemia (28 [15%] vs 14 [15%]), and diarrhoea (28 [15%] vs 11 [11%]). Serious treatment-emergent adverse events occurred in 93 (48%) patients in the venetoclax group and 48 (50%) patients in the placebo group, with eight (4%) treatment-emergent fatal infections reported in the venetoclax group and none reported in the placebo group. Three deaths in the venetoclax group (two from pneumonia and one from septic shock) were considered treatment-related; no deaths in the placebo group were treatment-related. The primary endpoint was met with a significant improvement in independent review committee-assessed progression-free survival with venetoclax versus placebo plus bortezomib and dexamethasone. However, increased mortality was seen in the venetoclax group, mostly because of an increased rate of infections, highlighting the importance of appropriate selection of patients for this treatment option.

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.

In this trial, 700 patients with myeloma were randomly assigned to receive RVD therapy (lenalidomide, bortezomib, and dexamethasone) with or without autologous stem-cell transplantation. Patients who underwent transplantation had significantly longer progression-free survival. For the past 20 years, high-dose chemotherapy plus autologous stem-cell transplantation has been the standard treatment for newly diagnosed multiple myeloma in adults up to 65 years of age. 1 – 3 However, this treatment requires hospitalization and can be associated with substantial toxic effects. Over the past decade, immunomodulatory drugs 4 – 14 and proteasome inhibitors 15 – 17 have been shown to have substantial activity in patients with multiple myeloma. The use of combination therapy with immunomodulatory drugs, proteasome inhibitors, and dexamethasone has yielded increased rates of complete response and improved outcomes, both among patients who are eligible for transplantation and among those who . . .

In patients with relapsed or refractory myeloma, 1-year progression-free survival was 20 percentage points higher with belantamab mafodotin, pomalidomide, and dexamethasone than with bortezomib, pomalidomide, and dexamethasone.
