The DANTE trial protocol: a randomised phase III trial to evaluate the Duration of ANti-PD-1 monoclonal antibody Treatment in patients with metastatic mElanoma.

BACKGROUND: Immunotherapy is revolutionising the treatment of patients diagnosed with melanoma and other cancers. The first immune checkpoint inhibitor, ipilimumab (targeting cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4)), showed a survival advantage over standard chemotherapy. Subsequently the anti-programmed cell death protein 1 (PD-1) antibodies, nivolumab and pembrolizumab were shown to be more effective than ipilimumab. Ipilimumab combined with nivolumab gives an incremental gain in overall survival compared with nivolumab alone but increases the risk of severe, potentially life-threatening toxicities. In contrast to ipilimumab monotherapy, anti-PD-1 antibodies are licensed to be continued until disease progression. Follow-up of patients recruited to the first trials evaluating 2 years of pembrolizumab showed that three-quarters of responding patients continue responding after stopping treatment. Suggestive of early response, we hypothesised that continuing anti-PD-1 treatment beyond 1 year in progression-free patients may be unnecessary and so designed the DANTE trial. METHODS: DANTE is a multicentre, randomised, phase III, non-inferiority trial to evaluate the duration of anti-PD-1 therapy in patients with metastatic (unresectable stage III and stage IV) melanoma. It uses a two-stage recruitment strategy, registering patients before they complete 1 year of first-line anti-PD-1 +/- CTLA-4 therapy and randomising eligible patients who have received 12 months of treatment and are progression-free at 1 year. At randomisation, 1208 patients are assigned (1:1) to either 1) continue anti-PD-1 treatment until disease progression/ unacceptable toxicity/ for at least 2 years in the absence of disease progression/ unacceptable toxicity or 2) to stop treatment. Randomisation stratifies for baseline prognostic factors. The primary outcome is progression-free survival at 3, 6, 9 and 12 months and then, 6-monthly for up to 4-years. Secondary outcomes collected at all timepoints include overall survival, response-rate and duration and safety, with quality of life and cost-effectiveness outcomes collected 3-monthly for up to 18-months. Sub-studies include a qualitative analysis of patient acceptance of randomisation and sample collection to inform future translational studies into response/ toxicity biomarkers. DISCUSSION: DANTE is a unique prospective trial investigating the optimal duration of anti-PD-1 therapy in metastatic melanoma patients. Outcomes will inform future use of these high burden drugs.

The Prehabilitation Radiotherapy Exercise, smoking Habit cessation and Balanced diet Study (PREHABS) protocol to explore the feasibility of embedding behavioural modifications into the clinical pathway for patients undergoing radical radiotherapy for lung cancer

Patients with curable non-surgical lung cancer are often current smokers, have co-existing medical comorbidities and are treated with curative radiotherapy. To maximise the benefits of modern radiotherapy, there is an urgent need to optimise the patient’s health to improve survival and quality of life.Methods and analysis The Yorkshire Cancer Research-funded Prehabilitation Radiotherapy Exercise, smoking Habit cessation and Balanced diet Study (PREHABS) (L426) is a single-centre prospective feasibility study to assess embedding behavioural changes into the radical radiotherapy pathway of patients with lung cancer. Feasibility will be assessed by measuring acceptability, demand and implementation. The duration of the study is 24 months. PREHABS has two workstreams: the intervention study and the theory of change (ToC) study.Intervention study: PREHABS will commence at the R-IDEAL phase 2 trial (exploratory) based on existing evidence and includes support for smoking cessation, increasing activity and dietary well-being. Patients undergoing radical radiotherapy for lung cancer will be recruited from the oncology department at Leeds Teaching Hospitals NHS Trust (LTHT). ToC study: to maximise the acceptability and adherence to the PREHABS, we will use a ToC approach to qualitatively explore the key barriers and enablers of implementing a tailored programme of ‘prehabilitation’. The PREHABS ToC study participants will be recruited from patients with lung cancer undergoing radical radiotherapy and staff from the LTHT oncology department.Analysis The primary endpoint analysis will report the number of participants and adherence to the study interventions. Secondary endpoints include continued engagement with study interventions post-treatment. The analysis will focus on descriptive statistics. Thematic analysis of the qualitative data from the ToC study will identify consensus on intervention optimisation and delivery

Can service integration work for universal health coverage? Evidence from around the globe

Universal health coverage (UHC) is at the heart of the new 2030 Agenda for Sustainable Development. Health service integration is seen by World Health Organization as an essential requirement to achieve UHC. However, to date the debate on service integration has focused on perceived benefits rather than empirical impact. We conducted a global review in a systematic manner searching for empirical outcomes of service integration experiments in UHC countries and those on the path to UHC. Sixty-seven articles and reports were found. We grouped results into a unique integration typology with six categories - medical staff from different disciplines; patients and medical staff; care package for one medical condition; care package for two or more medical conditions; specialist stand-alone services with GP services; community locations. We showed that it is possible to integrate services in different human development contexts delivering positive outcomes for patients and clinicians without incurring additional costs. However, the improved outcomes shown were incremental rather than radical and suggest that integration is likely to enhance already well established systems rather than fundamentally changing the outcomes of care

The use of cognitive interviewing methodology in the design and testing of a screening tool for supportive and palliative care needs.

Goals of work The authors describe the use of cognitive interviewing methodology in the development of a new supportive and palliative care screening measure to identify the specialist supportive and palliative care needs of patients with an advanced illness. Materials and methods A draft screening measure was developed by literature reviewing and consultation with patients, carers and health and social care professionals. Using this draft, cognitive interviews were conducted with six professionals and one consumer using the ‘thinking aloud technique’ to assess the perception, usefulness and interpretation of each question on the measure. The focus of these interviews was to identify unclear words or phrases and to explore how the questions worked in eliciting a response. A content analysis of the interviews was used to identify problems with the text, phrasing and format of the questions and accompanying responses. Main results The authors found the technique to be useful in identifying jargon or confusing questions. A number of perspectives were taken into account by speaking to health and social care professionals in primary care and secondary care who would be offering the measure to future patients. Conclusions The most sensitive questions were highlighted, and this enabled the researchers to consider how these should be asked and responded to in subsequent versions of the measure. The measure was re-drafted in light of these comments

NIHR Liver/Renal Biomarker Programme Final Report: Evaluating the benefits for patients and the NHS of new and existing biological fluid biomarkers in liver and renal disease

Protein biomarkers are naturally occurring substances that can be measured, often in fluids such as blood or urine, and which provide information about a patient and their illness. Different diseases have different biomarkers. When people become ill, changes in biomarker levels may occur before any clinical symptoms or signs become apparent. Measuring biomarkers in blood or urine is simple, safe and may help the doctor diagnose which disease the patient has, determine how severe it is, help choose the best treatment and help detect if the disease is getting worse or better. Unfortunately, for many diseases there are not enough biomarkers that are of proven usefulness in patient care today. New developments in research mean that many more are now being discovered but there is no quick and reliable way to decide which of the markers are good enough to be useful clinically. While our research proposal focusses on diseases of the liver and kidney, in the future it can also serve as the "blueprint" for similar work in other diseases. It is aimed at developing a structure and methods to assess the clinical usefulness of biomarkers as quickly and efficiently as possible. The research is divided into three parallel workstreams : 1. Identification of the best research methods for monitoring disease or treatment with biomarkers - the lack of understanding this has hampered this field so far. 2. The creation of a sample "banking" system for collecting and storing patient samples and relevant clinical data from large numbers of patients. This will allow the immediate testing of potential new biomarkers now and in the future. The best biomarkers would then go on to full trials to see if patients and the NHS would benefit from their use. 3. A clinical trial at multiple hospitals in the UK of three new biomarkers for liver damage (together called the "Enhanced liver fibrosis" or "ELF", test). We will find out if ELF can give early warning of dangerous liver damage (cirrhosis) and therefore reduce the risk of major complications. This trial may radically alter the way in which patients with liver disease can be looked after clinically. This research programme will benefit patients and the NHS by ensuring that biomarkers in the future can be evaluated and introduced more rapidly, improving clinical management for each individual patient and leading to better use of NHS resources
