Background: The diffuse large B-cell lymphoma (DLBCL) variant of Richter transformation (DLBCL-RT) is typically chemoresistant with poor prognosis. Aiming to explore a chemotherapy-free treatment combination that triggers anti-tumour immune responses, we conducted a phase 2 study of atezolizumab (a PD-L1 inhibitor) in combination with venetoclax and obinutuzumab in patients with DLBCL-RT., Methods: This was a prospective, open-label, multicentre, single-arm, investigator-initiated, phase 2 study in 15 hospitals in Italy and Switzerland. Eligible patients had a confirmed diagnosis of chronic lymphocytic leukaemia or small lymphocytic lymphoma as per the International Workshop on Chronic Lymphocytic Leukemia (IWCLL) 2008 criteria with biopsy-proven transformation to DLBCL; had not previously received treatment for DLBCL-RT, although they could have received chronic lymphocytic leukaemia therapies; were aged 18 years or older; and had an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2. No previous treatment with any of the drugs in the triplet combination was allowed. Patients received 35 cycles of 21 days of intravenous obinutuzumab (100 mg on day 1, 900 mg on day 2, 1000 mg on day 8 and day 15 of cycle 1; 1000 mg on day 1 of cycles 2-8) and intravenous atezolizumab (1200 mg on day 2 of cycle 1 and 1200 mg on day 1 of cycles 2-18), and continuous oral venetoclax (ramp-up from 20 mg/day on day 15 of cycle 1 according to chronic lymphocytic leukaemia schedule, then 400 mg/day from day 1 of cycle 3 to day 21 of cycle 35). The primary endpoint was overall response rate at day 21 of cycle 6 in the intention-to-treat population. We considered an overall response rate of 67% or more to be clinically active, rejecting the null hypothesis of a response of 40% or less. The study is registered with ClinicalTrials.gov, NCT04082897, and has been completed., Findings: Between Oct 9, 2019, and Oct 19, 2022, 28 patients were enrolled (12 [43%] male patients and 16 [57%] female patients). Median follow-up was 16·8 months (IQR 7·8-32·0). At cycle 6, 19 of 28 patients showed a response, yielding an overall response rate of 67·9% (95% CI 47·6-84·1). Treatment-emergent adverse events that were grade 3 or worse were reported in 17 (61%; 95% CI 40·6-78·5) of 28 patients, with neutropenia being the most frequent (11 [39%; 21·5-59·4] of 28 patients). Serious treatment-emergent adverse events were reported in eight (29%; 14·2-48·7) patients, which were most commonly infections (five [18%; 6·1-36·9] of 28 patients). There were two (7%) deaths attributable to adverse events during the study: one from sepsis and one from fungal pneumonia, which were not considered as directly treatment-related by the investigators. Six (21·4%) patients had immune-related adverse events, none of which led to discontinuation. No tumour lysis syndrome was observed., Interpretation: The atezolizumab, venetoclax, and obinutuzumab triplet combination was shown to be active and safe, suggesting that this chemotherapy-free regimen could become a new first-line treatment approach in patients with DLBCL-RT., Funding: Roche., Competing Interests: Declaration of interests AT reports payment or honoraria for lectures, presentations, speakers bureaus, manuscript writing, or educational events from Janssen, Beigene, and Abbvie; support for attending meetings or travel from Abbvie, Janssen, and Beigene; and participation on a data safety monitoring board or advisory board from Janssen, Abbvie, Beigene, Lilly, and AstraZeneca.

Objective: To understand the knowledge and awareness of palliative care in the Italian-speaking Swiss general population, describing main misconceptions or false beliefs and their relationship with attitudes towards palliative care., Methods: Cross-sectional representative population survey (N = 313)., Results: We observed a high awareness of «palliative care,» although it is mainly associated with pain management and the very last days of life. While false beliefs are relatively rare, there is low awareness of goals, targets, and services offered by palliative care. Overall the Italian-speaking Swiss population has a good predisposition towards palliative care, but negative attitudes are more common among those who lack knowledge. More than one-third of respondents are interested in receiving more information about palliative care, especially from their healthcare providers or through dedicated information points., Conclusion and Practice Implications: Health communication interventions to promote palliative care are needed because there is still significant unclarity about the goals of palliative care, which negatively affects its acceptance. This study instructs on how to intervene specifically in the Italian-speaking part of Switzerland, including what to communicate and how. Further, our findings can inspire similar studies in other Swiss regions or countries that can optimize recognition, knowledge, and understanding and contribute to filling gaps in populations' health service demand and utilization., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Diviani et al.
