We aimed to assess patient-reported outcomes in patients with HRR-deficient metastatic castration-resistant prostate cancer in TALAPRO-2.<h3>Methods</h3>TALAPRO-2 is a randomised, double-blind, placebo-controlled, phase 3 trial conducted at 223 hospitals, cancer centres, and medical centres in 26 countries worldwide. Eligible participants were male patients aged 18 years or older (≥20 years in Japan) who were receiving ongoing androgen deprivation therapy, had asymptomatic or mildly symptomatic metastatic castration-resistant prostate cancer, an Eastern Cooperative Oncology Group performance status of 0 or 1, and had not received previous life-prolonging systemic therapy for castration-resistant prostate cancer or metastatic castration-resistant prostate cancer. Patients with HRR gene alterations were randomly assigned (1:1) using a centralised interactive web response system and a permuted block size of 4 to oral talazoparib 0·5 mg once daily or placebo, plus oral enzalutamide 160 mg once daily, stratified by previous second-generation androgen receptor pathway inhibitor (abiraterone or orteronel) or docetaxel (yes vs no) in the castration-sensitive setting. The sponsor, patients, and investigators were masked to allocation of talazoparib or placebo; enzalutamide was open-label. The primary endpoint was radiographic progression-free survival by blinded independent central review and has been reported previously. Patient-reported outcomes were assessed as secondary outcomes in the patient-reported outcomes population, which comprised patients from the intention-to-treat population with a baseline patient-reported outcome assessment and at least one post-baseline patient-reported outcome assessment. Patient-reported outcomes included time to definitive deterioration in global health status/quality of life (GHS/QoL) per European Organisation for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30) and prostate cancer-specific urinary symptoms per EORTC Quality of Life Questionnaire-Prostate (QLQ-PR25), and time to deterioration in pain symptoms per Brief Pain Inventory-Short Form (BPI-SF). Mean change from baseline in GHS/QoL, overall cancer and prostate cancer-specific functioning and symptoms (per EORTC QLQ-C30 and QLQ-PR25), in pain symptoms per BPI-SF, and in general health status per EQ-5D-5L were also patient-reported secondary outcomes.

These audits are a collaboration between clinical leaders, methodological experts, professional organisations, civil society, and policy makers to develop and implement performance measures across all NHS cancer care and inform quality improvement of the care pathway. The aims of NATCAN are to provide transparent and timely feedback to hospitals about their practices and outcomes of cancer care, identify opportunities for improvement of cancer care, and support hospitals to conduct quality-improvement initiatives. The key methods used to achieve these aims were use of routinely collected data that did not necessitate bespoke collection by health-care staff specifically for the audit; public reporting of outcomes of care at hospital and regional levels; assessment of determinants of variation in cancer care to target quality improvement; and a central governance structure to ensure that unsafe care or outlying performance were managed effectively and promptly.

Patients were randomly assigned (1:1) to MIRV or investigator's choice of chemotherapy, stratified by number of previous therapy lines and the type of investigator's choice of chemotherapy.

A solely commercial development model will not deliver optimally due to insufficient return on investment for pharmaceutical companies. Access to therapies is restricted for patients who might benefit and advancing innovation in the academic research setting is difficult. Challenges relating to CAR T-cell therapies in paediatric malignancies and how they might be addressed were discussed in a meeting convened by ACCELERATE—an international multistakeholder organisation aiming to advance the timely investigation of new anticancer drugs. New academic and biopharma hybrid development models could benefit rare populations and coordination of early development can promote synergy and avoid duplicative efforts. Following promising first-in-child trials, new models are needed to support pivotal trials, decentralised manufacturing, registration, and reduced costs. The European Medicines Agency and the US Food and Drug Administration encourage academic development and early discussions. A biotech company funded via a pooled investment vehicle could provide access to safe and effective products for children and adolescents with cancer through registration and reimbursement.","PeriodicalId":22865,"journal":{"name":"The Lancet Oncology","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Enhanced precision in radiotherapy has not only reduced patient side-effects, but also enabled the delivery of high-dose stereotactic extracranial irradiation with unprecedented accuracy. Simultaneously, the number of medical therapies available for clinical care continues to grow. Despite the progress made with combined chemoradiotherapy, only a few drug–radiotherapy combinations have received clinical approval, leaving a vast landscape of untapped opportunities for basic, translational, and clinical research, particularly in early-phase drug–radiotherapy trials. New and promising pharmaceutical therapies, paired with advanced radiotherapy technologies, are now being tested in innovative clinical trial designs. Moreover, the integration of biological and imaging markers—both tumour-specific and peripheral—holds the potential to personalise drug–radiotherapy combinations, thereby enhancing the therapeutic index for specific patient populations. In this Review, we highlight the latest developments and future directions for early-phase clinical trials that combine precision drug–radiotherapy strategies in adult patients, with the aims of improving outcomes and expanding treatment options.","PeriodicalId":22865,"journal":{"name":"The Lancet Oncology","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consensus guidelines inform the management of immune effector cell-associated neurotoxicity syndrome (ICANS). However, these guidelines are based on the early clinical experience with CD19 targeting CAR T cells in B-cell malignancies. In contrast, there are so far no published best practice recommendations on the current management of other non-classical neurological complications, which frequently develop after CAR T-cell infusion and cause clinically significant neurotoxicity. These non-classical neurological complications could be more prevalent because of additional CAR T-cell targets (eg, B cell maturation antigen [BCMA]), widened access, new indications in clinical development (including solid tumours in the CNS), and long-term follow-up. In this Review, the European Society for Blood and Marrow Transplantation (EBMT) Practice Harmonisation and Guidelines Committee provides recommendations on the management of CAR T-cell associated neurological complications that occur after treatment with the licensed CD19 and BCMA CAR T cells, as well as neurological toxicities that are emerging with CAR T cells in clinical trials for solid and haematological cancers. We address movement and neurocognitive toxicity, cranial nerve palsies, tumour inflammation-associated neurotoxicity, stroke, myelopathy, peripheral neuropathy, Guillain–Barré syndrome, fludarabine-associated neurotoxicity, and provide guidance on the psychological support for patients.
