Trial Status

Cancer Type

Oesophageal Cancer, Stomach Cancer

Protocol Title

A Randomised Phase III Double-Blind Placebo-Controlled Study of regorafenib in Refractory Advanced Gastro-Oesophageal Cancer (AGOC)

Purpose of the Study

This study follows the success of the Phase II INTEGRATE study, which demonstrated a positive signal with regorafenib. The purpose of INTEGRATE II is to determine whether Regorafenib improves overall survival as a third line therapy in refractory AGOC. The primary objective is overall survival, while secondary objectives include progression free survival, objective response rates, safety, quality of life, and investigation in patient populations from different geographic regions.

Eligibility Criteria

Inclusion Criteria

  • Adults (18 years or over) with metastatic or locally recurrent gastro-oesophageal cancer
  • Patients who have failed or have been intolerant to 2 prior courses of chemotherapy for advanced gastro-oesophageal cancer
  • Ability to swallow oral medication
  • Adequate kidney, bone marrow, renal, liver and cardiac function

Exclusion Criteria

  • Known allergy to Regorafenib or its excipients
  • Patients with significant active infection, which include chronic active hepatitis B, C or HIV
  • Poorly controlled hypertension (blood pressure)
  • Known uncontrolled malabsorption syndromes
  • Had treatment with any drug therapies within the 28 days prior to randomisation
  • Patients who have had major surgery, open biopsy or major traumatic injury within the 28 days prior to randomisation
  • Pregnancy.

Integrate II: A randomised phase 3 double-blind placebo-controlled study of regorafenib in refractory advanced gastro-oesophageal cancer—an international study organized by the Australasian Gastrointestinal Trials Group. American Society of Oncology Annual Meeting; 2–6 Jun 2017; Chicago.

Aim

This study follows the success of the Phase II INTEGRATE study, which demonstrated a positive signal with regorafenib. The purpose of INTEGRATE II is to determine whether Regorafenib improves overall survival as a third line therapy in refractory AGOC. The primary objective is overall survival, while secondary objectives include progression free survival, objective response rates, safety, quality of life, and investigation in patient populations from different geographic regions.

Background

INTEGRATE II is a phase III international multi-centre clinical trial to determine whether Regorafenib is effective in prolonging survival in patients with Advanced Gastro-Oesophageal Carcinoma.

The purpose of this clinical trial is to confirm the activity seen in a previous clinical trial (INTEGRATE), which demonstrated the efficacy of Regorafenib in Advanced Gastro-Oesophageal cancer.

Currently, there are few treatment options for patients with advanced gastro-oesophageal carcinoma that has progressed after first and second line chemotherapy.

Regorafenib is being explored as a possible alternative treatment option. Regorafenib is a multi-targeted therapy that targets a number of signals in the cancer cell that cause it to grow and produce blood vessels. Regorafenib has been proven to have a benefit when other drugs have ceased to work in other cancers, such as colon cancer, liver cancer and gastrointestinal stromal tumours (GIST).

CLINICAL TRIAL DESIGN

INTEGRATE II is a randomised phase III, double-blind, controlled trial with 2:1 randomisation with stratification by the location of tumour, geographic region and prior VEGF inhibitors.

Participants in the trial will be randomly allocated to one of two groups: to receive either Regorafenib or a placebo tablet. The Regorafenib/placebo will be taken once per day for the first 21 days, every four weeks.

Participants will be followed up every 2-4 weeks to evaluate how they are responding to treatment. The effectiveness of the treatment will be evaluated by CT scan every 8 weeks.  Throughout the trial the participant’s medical oncologist will determine whether the participant in suitable for ongoing therapy. Treatment will continue until there is cancer progression or adverse events that prohibit the study from progressing.

There will also be follow up with the patient every 2 months to determine survival.

Participants will not know whether they are taking Regorafenib or the placebo until after the trial is completed. It is planned that the trial will be conducted over two years.

Translational studies will also be conducted to see which patients may benefit the most from this treatment. This will be done by detecting certain biomarkers and drug levels in tumour tissue and blood samples of patients who give consent to participate in these studies.
