Study summary

The investigators aim to ascertain how food reward signals and eating behaviour relates to the gut-brain pathway in weight-losing patients after curative surgery for oesophageal cancer, and how this pathway responds to clinical treatment for this unintentional weight loss. The primary outcomes are the blood oxygen level dependent (BOLD) signal on functional MRI (fMRI), and the breakpoint during the progressive ratio task (PRT - a measure of eating behaviour), how these differ in response to multiple clinical treatment options, as well as how they relate to weight gain while on treatment.

Read the detailed description

The incidence of cancer of the oesophagus (food pipe) is increasing. Improvements in treatment strategies have resulted in more people who remain free from cancer recurrence in the long term following treatment.

Surgery is the cornerstone of treatment for patients with oesophageal cancer, but while surgical removal of the tumour (oesophagectomy) may offer the best chance of cure, these are major operations associated with specific long term complications. Poor appetite, weight loss and nutritional impairment are common problems among patients who attain long-term cancer remission and cure after surgery.

A new clinic has been established to treat patients who are in remission but who have lost more than 10% of their body weight secondary to the effects of the surgery and struggling to regain weight. These patients will be treated as per standard of care with medications to aid weight gain.

The investigators are interested to conduct research into how the reward value of food changes during the clinical treatment pathway. The hypothesis is that there will be an increased reward response to food after medication use, the magnitude of which will correlate with weight gain. To assess this, patients who are already part of this clinic will be approached to have fMRI that can demonstrate changes in brain reward centres as well as a Progressive Ratio Task, which is a direct measure of appetitive behaviour. Changes in brain reward centre responses and appetitive behaviour will be correlated with changes in weight after pharmacotherapy. This may further inform future clinical protocols to provide improved precision medicine.

Study population

A cohort of post-esophagectomy patients at least 1 year after curative surgery, but struggling with unintentional weight loss of at least 10% baseline body weight, and thus candidates for clinical treatment.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. History of esophagectomy with gastric conduit reconstruction
  2. Recurrence-free at least 12 months post-operatively
  3. Weight loss ≥10% from premorbid weight, or requiring ongoing caloric supplementation
  4. Due to undergo clinical treatment for weight loss with Sandostatin or Mirtazapine

Exclusion criteria

Exclusion Criteria:

  1. Pregnancy, breastfeeding
  2. Significant and persistent chemoradiotherapy and/or surgical complication
  3. Other active
  4. Exocrine pancreatic insufficiency detected using fecal elastase
  5. Uncontrolled diabetes mellitus
  6. Significant psychiatric disorder or cognitive decline or communication impairment limiting capacity to provide
  7. Severe dysphagia
  8. Other disease or medication which may impact gut hormone physiology
  9. History of significant food allergy, certain dietary restrictions
  10. Any definite to somatostatin analogue administration
  11. Claustrophobia, or any absolute contraindication to MRI scanning
  12. Metallic implants, precluding fMRI
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Groups and cohorts

  • Sandostatin

    This cohort will be the group who are undergoing routine clinical treatment with a long-acting somatostatin analogue to minimise abnormal gut hormone signalling, and thus reduce early satiety.

    Other: Clinical treatment

  • Mirtazapine

    This cohort will be the group who are undergoing routine clinical treatment with a tetracyclic antidepressant to stimulate appetite.

    Other: Clinical treatment

Interventions

  • OtherClinical treatment

    Patients undergo clinical treatment as indicated, they are studied before and after.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 27, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
