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 this issue, Walter et al. report the results of two clinical trials of a new therapeutic vaccine, IMA901, for the treatment of renal cell carcinoma (RCC). IMA901 consists of ten tumor-associated peptides identified as naturally presented T cell epitopes in RCC, and the authors show longer overall survival in subjects with immune responses to multiple vaccine peptides and identify serum and cellular biomarkers that may help predict overall survival in future studies of the vaccine. IMA901 is the first therapeutic vaccine for renal cell cancer (RCC) consisting of multiple tumor-associated peptides (TUMAPs) confirmed to be naturally presented in human cancer tissue. We treated a total of 96 human leukocyte antigen A (HLA-A)*02 + subjects with advanced RCC with IMA901 in two consecutive studies. In the phase 1 study, the T cell responses of the patients to multiple TUMAPs were associated with better disease control and lower numbers of prevaccine forkhead box P3 (FOXP3) + regulatory T (T reg ) cells. The randomized phase 2 trial showed that a single dose of cyclophosphamide reduced the number of T reg cells and confirmed that immune responses to multiple TUMAPs were associated with longer overall survival. Furthermore, among six predefined populations of myeloid-derived suppressor cells, two were prognostic for overall survival, and among over 300 serum biomarkers, we identified apolipoprotein A-I (APOA1) and chemokine (C-C motif) ligand 17 (CCL17) as being predictive for both immune response to IMA901 and overall survival. A randomized phase 3 study to determine the clinical benefit of treatment with IMA901 is ongoing.

The treatment outcome for diffuse large B-cell lymphoma has not been improved in nearly 20 years. However, the replacement of vincristine in R-CHOP with polatuzumab vedotin, an anti-CD79b antibody linked to emtansine, led to a progression-free survival benefit over R-CHOP at 2 years (76.7% vs. 70.2%), with a similar safety profile.

This international prospective study showed that maintenance therapy with rituximab was more effective than interferon alfa in prolonging the duration of remission and extending survival in older patients with mantle-cell lymphoma. Patients with mantle-cell lymphoma typically present with extensive disease and involvement of multiple lymph nodes as well as the spleen, bone marrow, blood, and gastrointestinal tract. The median age at diagnosis is about 65 years. 1 , 2 Standard therapy for these patients consists of chemotherapy (e.g., the CHOP regimen, consisting of cyclophosphamide, doxorubicin, vincristine, and prednisone) combined with the anti-CD20 monoclonal antibody rituximab (e.g., R-CHOP). 2 – 4 Only a minority of patients have a complete remission, and relapse or progression usually occurs within 2 to 3 years, resulting in an overall survival of less than 5 years. To improve this grim prognosis, . . .

Preferred neoadjuvant regimens for early-stage triple-negative breast cancer (TNBC) include anthracycline-cyclophosphamide and taxane-based chemotherapy. IMpassion031 compared efficacy and safety of atezolizumab versus placebo combined with nab-paclitaxel followed by doxorubicin plus cyclophosphamide as neoadjuvant treatment for early-stage TNBC. This double-blind, randomised, phase 3 study enrolled patients in 75 academic and community sites in 13 countries. Patients aged 18 years or older with previously untreated stage II–III histologically documented TNBC were randomly assigned (1:1) to receive chemotherapy plus intravenous atezolizumab at 840 mg or placebo every 2 weeks. Chemotherapy comprised of nab-paclitaxel at 125 mg/m2 every week for 12 weeks followed by doxorubicin at 60 mg/m2 and cyclophosphamide at 600 mg/m2 every 2 weeks for 8 weeks, which was then followed by surgery. Stratification was by clinical breast cancer stage and programmed cell death ligand 1 (PD-L1) status. Co-primary endpoints were pathological complete response in all-randomised (ie, all randomly assigned patients in the intention-to-treat population) and PD-L1-positive (ie, patients with PD-L1-expressing tumour infiltrating immune cells covering ≥1% of tumour area) populations. This study is registered with ClinicalTrials.gov (NCT03197935), Eudra (CT2016-004734-22), and the Japan Pharmaceutical Information Center (JapicCTI-173630), and is ongoing. Between July 7, 2017, and Sept 24, 2019, 455 patients were recruited and assessed for eligibility. Of the 333 eligible patients, 165 were randomly assigned to receive atezolizumab plus chemotherapy and 168 to placebo plus chemotherapy. At data cutoff (April 3, 2020), median follow-up was 20·6 months (IQR 8·7–24·9) in the atezolizumab plus chemotherapy group and 19·8 months (8·1–24·5) in the placebo plus chemotherapy group. Pathological complete response was documented in 95 (58%, 95% CI 50–65) patients in the atezolizumab plus chemotherapy group and 69 (41%, 34–49) patients in the placebo plus chemotherapy group (rate difference 17%, 95% CI 6–27; one-sided p=0·0044 [significance boundary 0·0184]). In the PD-L1-positive population, pathological complete response was documented in 53 (69%, 95% CI 57–79) of 77 patients in the atezolizumab plus chemotherapy group versus 37 (49%, 38–61) of 75 patients in the placebo plus chemotherapy group (rate difference 20%, 95% CI 4–35; one-sided p=0·021 [significance boundary 0·0184]). In the neoadjuvant phase, grade 3–4 adverse events were balanced and treatment-related serious adverse events occurred in 37 (23%) and 26 (16%) patients, with one patient per group experiencing an unrelated grade 5 adverse event (traffic accident in the atezolizumab plus chemotherapy group and pneumonia in the placebo plus chemotherapy group). In patients with early-stage TNBC, neoadjuvant treatment with atezolizumab in combination with nab-paclitaxel and anthracycline-based chemotherapy significantly improved pathological complete response rates with an acceptable safety profile.

In a randomized trial of bortezomib, cyclophosphamide, and dexamethasone as compared with the same therapy plus daratumumab, patients with light-chain amyloidosis who received daratumumab had a higher frequency of hematologic complete response than those who did not (53.3% vs. 18.1%). Deaths were most commonly due to cardiac failure.

Among patients with triple-negative breast cancer, 5-year survival was 86.6% with neoadjuvant pembrolizumab with chemotherapy followed by adjuvant pembrolizumab and 81.7% with neoadjuvant chemotherapy alone.

Patients with CLL received chemoimmunotherapy, venetoclax–rituximab, venetoclax–obinutuzumab, or venetoclax–obinutuzumab–ibrutinib; the latter two groups had deeper responses and longer progression-free survival.

Patients 70 years of age or younger with previously untreated CLL were randomly assigned to receive ibrutinib plus rituximab or chemoimmunotherapy with fludarabine, cyclophosphamide, and rituximab. The ibrutinib-based regimen led to prolonged progression-free and overall survival.

Scleroderma is a life-threatening autoimmune disease in need of more effective treatment. A randomized trial of myeloablative therapy followed by autologous CD34+ hematopoietic stem-cell transplantation showed outcomes that were superior to those with monthly cyclophosphamide.
