The Cancer Research UK Prevention Trials Unit (CPTU) was established in 2006 to provide clinical trials unit (CTU) support to the Centre for Cancer Prevention (CCP) at the Wolfson Institute of Preventive Medicine (WIPH), part of Barts and The London School of Medicine and Dentistry (SMD), one of the three faculties of Queen Mary University of London.
In 2019, the CPTU moved to King’s College London, joining the Cancer Prevention Group within the Comprehensive Cancer Centre at the School of Cancer & Pharmaceutical Sciences, Faculty of Life Sciences and Medicine.
At the end of 2023, the CPTU returned to Queen Mary University of London to establish the Centre for Cancer Screening, Prevention and Early Diagnosis at the WIPH, relaunching the CPTU at QMUL.
Director of the CRUK CPTU, Professor Sasieni CBE is internationally recognised for his transformational work on the design and execution of clinical trials in cancer early detection and prevention. Professor Sasieni was awarded a CBE for services to cancer early detection and prevention in December 2024.
• “‘INSIGHT’ Psychological and behavioural aspects of Cytosponge screening for Barrett’s oesophagus: generating evidence to inform implementation” – Led by Professor Jo Waller, QMUL. Funder: Cancer Research UK (2024)
• “CRUK Cancer Prevention Trials Unit (CPTU) Core renewing funding award - CRUK CRC Clinical Trials Unit” – Led by Prof Sasieni, QMUL. Funder: Cancer Research UK (2023)
• “BEST4: A Platform Trial to determine whether Cytosponge-biomarker technology reduces mortality” - Led by Prof Fitzgerald, University of Cambridge, and Prof Sasieni, QMUL. Funder: Cancer Research UK and National Institute for Health and Care Research (2022)
The BEST4 Screening trial opened to recruitment in November 2024. The trial aims to explore if the capsule sponge can prevent deaths from oesophageal cancer when offered as a screening test to people on long-term medication for heartburn – one of the most common Barrett's oesophagus symptoms. The trial aims to recruit 120,000 participants.
The UK National Screening Committee (UKNSC) is now consulting on offering HPV self-sampling to under-screened people in the cervical screening programme. YouScreen evaluated the feasibility of HPV self-sampling for cervical screening non-attenders within the NHS cervical screening programme in England. Evidence found that offering self-sampling to under-screened people was both feasible and increased engagement with screening.
Active follow-up for NHS-Galleri was completed in the summer of 2024. NHS-Galleri is a randomised controlled trial of the multi-cancer early detection blood test developed by GRAIL. With over 140,000 participants taking part, it represents the world’s largest research trial of a multi-cancer early detection blood test. Passive follow-up is ongoing with analysis scheduled to take place at the end of 2025.
On receiving his CBE, Professor Sasieni said: “I would like to recognise and thank the many colleagues whose contributions have enabled me and my team to make great progress in cancer detection and prevention."
