Plain English summary of protocol

Background and study aims
Cancer of Unknown Primary (CUP) is where cancer cells are found in the body but the place the cancer began is not known. It is the 6th leading cause of cancer death in the UK and the prognosis is poor with a median survival of 6-9 months. There is a higher than average incidence of CUP in the North West (NW) of England (population of 7.4 million). Precision medicine has transformed treatment strategies in known tumour types, however in CUP there remains an urgent need to better understand CUP molecular characteristics to establish potential roles for novel therapeutic strategies. Treatment options remain limited due to difficulties in determining the primary site of the tumour and the lack of access to validated biomarkers. Access to good-quality tissue for molecular profiling remains a huge challenge in CUP. The emergence of liquid biopsies (sequence DNA in a blood test) as a source of biomarkers is also gaining rapid ground and this study aims to explore the potential utility of liquid biopsies in CUP.

Who can participate?
Patients aged 16 years or over with Cancers of Unknown Primary

What does the study involve?
Participants will attend a baseline visit where their medical history and some clinical data will be collected and recorded by the study team. Adverse and serious adverse event information will be collected throughout. Additional clinical data will be recorded once participants have progressed on their treatment and to follow participants up, up to 12 months later.
At baseline, the following samples will be collected:
1. Up to 40 ml of blood
2. Archival tumour blocks from a previous biopsy will be retrieved/requested. Samples will only be sent for analysis if blood samples fail to report a result.
When participants progress from their treatment, the following samples will be collected:
1. Up to 20 ml of blood
Samples will be sent to collaboration research laboratories for DNA analysis. The results from this analysis will be reported back to the participant's research team.

What are the possible benefits and risks of participating?
Although the objectives of this study are not directly therapeutic and therefore may not have a direct benefit for all participants, it is anticipated that the results from the tests may help direct some participants to a suitable treatment option. There is also the benefit of increased knowledge about molecular changes in their cancer which some patients may also find useful.
General risks associated with data collection apply. Minor risks are associated with blood sample collection such as bruising and pain. Genetic research may result in psychological distress if results show other previously unknown conditions (e.g., hereditary conditions). All participants will receive the appropriate information about this at the time of consent and will be given the option to not have any such results disclosed.

Where is the study run from?
The Christie (lead centre) (UK)

When is the study starting and how long is it expected to run for?
December 2023 to February 2028

Ethics approval(s)Approved 28/06/2024, North West - Haydock Research Ethics Committee (2 Redman Place, Stratford, London, E20 1JQ, UK; +44 (0)207 104 8032; haydock.rec@hra.nhs.uk), ref: 24/NW/0181
Health condition(s) or problem(s) studiedCancer of unknown primary
InterventionStudy population:
Patients with a confirmed diagnosis of Cancer of Unknown Primary (CUP) will be recruited from six North-West-based NHS hospitals.

Consent:
All participants will be provided with a patient information sheet (PIS) and will be given sufficient opportunity to review and ask questions about the information before being asked to voluntarily consent to the study. Consent will be obtained by an appropriately trained and delegated member of the study team at a point that they are confident the participant fully understands the information they have received.

Data collection:
Only once fully informed consent has been obtained, participants will attend a baseline visit. During this visit their medical history and some clinical data will be collected and recorded by the study team. Adverse and serious adverse event information will be collected throughout. Additional clinical data will be recorded once participants have progressed on their treatment and to follow participants up, up to 12 months post baseline.

Sample collection:
At baseline, the following samples will be collected:
1. Up to 40 ml blood for circulating tumour DNA (ctDNA) and STRECK samples.
2. Archival tumour blocks from a prior biopsy will be retrieved/requested. Samples will only be sent for analysis if blood samples fail to report a result.

When participants progress from their treatment, the following samples will be collected:
1. Up to 20 ml blood for circulating tumour DNA (ctDNA)

Samples will be sent to collaboration research laboratories at Penzburg, Germany (or Boston, USA as a backup) for circulating tumour DNA (ctDNA) analysis. The results from this analysis will be reported back to the participant's research team and will be discussed in the molecular tumour board.

STRECK blood samples will processed and transferred to the Cancer Biomarker Centre to be used for research of a methylation assay.
Intervention typeOther
Primary outcome measureThe utility of cfDNA molecular profiling in patients diagnosed with CUP as determined by:
1. Percentage of patients with adequate cfDNA yields measured using FoundationOne®️ Liquid CDx testing of blood samples obtained at baseline or progression timepoints
2. Percentage of patients with actionable genomic alterations measured using FoundationOne®️ Liquid CDx testing of blood samples obtained at baseline or progression timepoints
3. Percentage of patients eligible for personalised treatment options or enrolment on a UK-based clinical trial because of the cfDNA results, measured using FoundationOne®️ Liquid CDx testing of blood samples obtained at baseline or progression timepoints
Secondary outcome measures1. Documentation and feedback of genomic results/GTAB outcomes to all patients and treating teams following FoundationOne®️ CDx or FoundationOne®️ Liquid CDx at baseline, and FoundationOne®️ Liquid CDx at progression
2. Routinely incorporate molecular genomics as standard of care in patients diagnosed with CUP (working with the NHS England Genomic Medicine Service) following FoundationOne®️ CDx or FoundationOne®️ Liquid CDx at baseline and FoundationOne®️ Liquid CDx at progression
3. Develop a data collection repository and readily available information on trials/treatments for patients diagnosed with CUP to be shared at monthly trial management group meetings to ensure that investigators are aware of suitable trial opportunities
