ClinConnect Summary

This clinical trial, titled "RegoNivo vs Standard of Care Chemotherapy in AGOC," is investigating whether a combination of two drugs, regorafenib and nivolumab (referred to as RegoNivo), can help patients with advanced gastro-oesophageal cancer live longer compared to current standard chemotherapy treatments. The trial is currently active but not recruiting new participants.

To be eligible for this trial, participants need to be adults (18 years or older) who have advanced gastro-oesophageal cancer that has returned after at least two previous treatments. They should also be in good overall health, able to swallow pills, and have stable blood counts and organ function. Participants will receive the study treatment and will be monitored regularly to see how well it works and how they tolerate it. It’s important to note that individuals with certain medical conditions or those who recently had specific treatments might not be able to join the study. Overall, this trial aims to find a potentially better treatment option for patients facing this challenging disease.

Eligibility criteria

• Inclusion Criteria:
• 1. Adults (18 years or over) with metastatic or locally recurrent gastro-oesophageal cancer which:
• • 1. has arisen in any primary gastro-oesophageal site (oesophago-gastric junction (GOJ) or stomach); and
• • 2. is of adenocarcinoma or undifferentiated carcinoma histology; and
• • 3. is evaluable according to Response Evaluation Criteria in Solid Tumours (RECIST Version 1.1) by computed tomography (CT) scan performed within 21 days prior to randomisation. A lesion in a previously irradiated area is eligible to be considered as measurable disease as long as there is objective evidence of progression of the lesion prior to study enrolment; and
• • 4. has failed or been intolerant to a minimum of 2 lines of prior anti-cancer therapy for recurrent/metastatic disease which must have included at least one platinum agent and one fluoropyrimidine analogue. Note: Neoadjuvant or adjuvant chemotherapy or chemoradiotherapy will be considered as first line treatment where people have relapsed or progressed within 6 months of completing treatment; Radiosensitising chemotherapy given solely for this purpose concurrent with palliative radiation will not be considered as a line of treatment. Ramucirumab monotherapy, or immunotherapy with a checkpoint inhibitor, will be considered a line of treatment.
• • 5. HER2-positive participants must have received trastuzumab
• • 2. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1 (Appendix 1).
• • 3. Ability to swallow oral medication.
• • 4. Adequate bone marrow function (Platelets ≥100x109/L; Absolute Neutrophil Count (ANC) ≥1.5x109/L and Haemoglobin ≥ 9.0g/dL).
• • 5. Adequate renal function (Creatinine clearance \>50 ml/min) based on either the Cockcroft-Gault formula (Appendix 2), 24-hour urine or Glomerular Filtration Rate (GFR) scan; and serum creatinine ≤1.5 x Upper Limit of Normal (ULN).
• • 6. Adequate liver function (Serum total bilirubin ≤1.5 x ULN, and INR ≤ 1.5 x ULN, and Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Alkaline phosphatase (ALP) ≤2.5 x ULN (≤ 5 x ULN for participants with liver metastases)).
• • Participants being treated with an anti-coagulant, such as warfarin or heparin, will be allowed to participate provided that no prior evidence of an underlying abnormality in these parameters exists.
• • 7. Willing and able to comply with all study requirements, including treatment, timing, and/or nature of required assessments and follow-up.
• • 8. Study treatment both planned and able to start within 7 days after randomisation (note: subjects randomised on a Friday should commence treatment no earlier than the following Monday)
• • 9. Signed, written informed consent
• Exclusion Criteria:
• • 1. Known allergy to the investigational product drug class or excipients in the regorafenib and/or nivolumab
• • 2. Poorly-controlled hypertension (systolic blood pressure \>140mmHg or diastolic pressure\> 90mmHg despite optimal medical management).
• • 3. Participants with known, uncontrolled malabsorption syndromes
• • 4. Any prior anti-VEGF targeted therapy using small molecule VEGF TKIs (e.g. apatinib). Prior anti-VEGF targeted monoclonal antibody therapies (e.g. bevacizumab and ramucirumab) are permitted.
• • 5. Any prior use of more than one immune checkpoint inhibitor
• • 6. Treatment with any previous drug therapy within 2 weeks prior to first dose of study treatment. This includes any investigational therapy.
• • 7. Use of biological response modifiers, such as granulocyte colony stimulating factor (G-CSF), within 3 weeks prior to randomisation.
• • 8. Concurrent treatment with strong CYP3A4 inhibitors or inducers.
• • 9. Palliative radiotherapy, unless more than 14 days have elapsed between completion of radiation and the date of registration, and adverse events resulting from radiation have resolved to \< Grade 2 according to CTCAE V5.0
• • 10. Major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to randomization
• • 11. Arterial thrombotic or ischaemic events, such as cerebrovascular accident, within 6 months prior to randomization.
• • 12. Venous thrombotic events and pulmonary embolism within 3 months prior to randomization
• • 13. Any haemorrhage or bleeding event ≥ Grade 3 according to CTCAE v5.0 within 4 weeks prior to randomization.
• • 14. Non-healing wound, ulcer, or bone fracture.
• • 15. Interstitial lung disease with ongoing signs and symptoms
• • 16. Clinical hyperthyroidism or hypothyroidism. Note: non-clinically significant abnormal TFTs (abnormal TSH and abnormal T3 and/or abnormal T4) considered to be due to sick euthyroid syndrome is allowed.
• • 17. Persistent proteinuria of ≥ Grade 3 according to CTCAE v5.0 (equivalent to \> 3.5g of protein over 24 hour measured on either a random specimen or 24 hour collection.
• • 18. Uncontrolled metastatic disease to the central nervous system. To be eligible, known CNS metastases should have been treated with surgery and/or radiotherapy and the patient should have been receiving a stable dose of steroids for at least 2 weeks prior to randomization, with no deterioration in neurological symptoms during this time.
• 19. History of another malignancy within 2 years prior to randomization. Participants with the following are eligible for this study:
• • 1. curatively treated cervical carcinoma in situ,
• • 2. non-melanomatous carcinoma of the skin,
• • 3. superficial bladder tumours (T1a \[Non-invasive tumour\], and Tis \[Carcinoma in situ\]),
• • 4. treated thyroid papillary cancer
• • 20. Any significant active infection, including chronic active hepatitis B, hepatitis C, or HIV. Testing for these is not mandatory unless clinically indicated. Participants with known Hepatitis B/C infection will be allowed to participate providing evidence of viral suppression has been documented and the patient remains on appropriate anti-viral therapy.
• • 21. Patients with acute coronary syndrome (including myocardial infarction and unstable angina), and with a history of coronary angioplasty or stent placement performed within 6 months before enrolment
• • 22. Patients with a ≥ grade 3 active infection according to CTCAE version 5.0

• • 25. Patients with a seizure disorder who require pharmacotherapy
