Topic: National Cancer Research Network; Subtopic: Colorectal Cancer; Disease: Colon, Rectum


This is a single arm multi-centre phase I/II study in patients with advanced colorectal cancer. Initially this will consist of a phase 1 dose escalation study in patients with advanced colorectal cancer whose disease has already grown despite a first course of chemotherapy. This phase will establish a recommended dose combination for the phase 2 study (RP2D).

The phase 2 study will evaluate this combination as a first line treatment in patients with metastatic colorectal cancer for whom standard doublet chemotherapy would not be deemed suitable.

Clinicians/research staff at participating research centres will review potential patients and assess their suitability for the trial. The patient must have a histologically proven colorectal cancer with evidence of metastatic disease. The clinician/research team member will then discuss the trial with the patient, who, if interested will be given a patient information sheet (PIS) to read and encouraged to ask any questions.

Once patients have consented to participate in the trial they will undergo a series of assessments and blood tests which are listed below:-

1. Full blood count and clotting screen
2. Urea and electrolytes, liver function tests (including ALP, AST or ALT, bilirubin)
3. Blood tests for serum creatinine to estimate glomerular filtration rate
4. Blood test for serum CEA tumour marker
5. Urine test
6. Echocardiogram (heart ultrasound scan)
7. Electrocardiogram (ECG)
8. CT scan of the chest, abdomen and pelvis to evaluate disease burden
9. Blood pressure measurement
10. Pregnancy test (if female and child bearing age)
11. Full medical history and current medications
12. Physical examination
13. ECOG performance status

For phase II patients nurses or dedicated research members will perform a questionnaire with the patients as part of a ‘Comprehensive Health Assessment’. This will include an assessment of other medical problems, a memory test and a questionnaire designed to assess function regarding activities of daily living. In addition to this the patients will also complete written questionnaires to assess overall quality of life.

The above information will then will used by doctors to decide if the patient meets the eligibility criteria of the trial.

Patients will also be asked if they would be willing to undergo a biopsy of their cancer for research purposes. This biopsy is purely optional and a refusal will not affect any further participation in the trial.

Once the patients have entered the trial they will receive the combination treatment. All patients will receive an IV infusion of Aflibercept (day 1) and start twice daily capecitabine tablets which they will take twice a day for 2 weeks. Each cycle is 3 weeks long and involves one week without treatment. The initial starting dose of Aflibercept is 6.5mg/kg + twice daily Capecitabine at a dose of 850mg/m2.

Before each cycle the patient will be seen by a doctor/dedicated research team member and undergo the following assessments

1. Full blood count and clotting screen
2. Urea and electrolytes, liver function tests (including ALP, AST or ALT, bilirubin)
3. Blood tests for serum creatinine to estimate glomerular filtration rate
4. Blood pressure measurement
5. Urine sample
6. Physical examination and toxicity assessment
7. ECOG performance status
8. Blood tests to assess pharmacodynamic parameters (week 1 and 3 in the first cycle)

At 12 and 24 weeks they will also have a repeat electrocardiogram (ECG) and a CT scan of the chest, abdomen and pelvis to assess disease response. For phase II patients only further questionnaires will be undertaken at 12 and 24 weeks to assess the impact of treatment on quality of life and activities of daily living.

Responses will be assessed by CT using RECIST criteria and if the patient’s disease is progressing they will no longer continue on the trial. Patients can also be withdrawn for toxicity reasons or if treatment is delayed for >3weeks. Following completion of the trial patients will be followed up for 28 calendar days after the last administration of the study drug. If there are adverse events that occurred while the patient was on study which are attributed (including possibly drug-related AEs) to the study drug and are still present 28 calendar days after the last administration of study drug or occur in the 28 calendar days post study drug administration; the patient will be followed up monthly afterwards until resolution or stabilisation of these events, unless the patient starts another anti-tumour treatment. Although the Investigator will make every reasonable effort to keep each patient on study until the patient progresses or receives the maximum number of cycles, the patient may be removed from the study for other reasons.

Intervention type



Phase I/II

Drug names

Capecitabine, aflibercept

Primary outcome measure

Phase I, primary outcome measure:
To evaluate the maximum tolerated dose in a selected group of patients with good performance status with metastatic disease who have progressed on at least first line therapy.

Phase II, primary outcome measure:
To establish safety and tolerability of recommended phase II treatment dose of aflibercept and capecitabine in patients not suitable for doublet/triplet cytotoxic chemotherapy.

Secondary outcome measures

Phase I, secondary outcome measure:
Overall response rate in this group and to evaluate the overall treatment toxicity profile in this

Phase II, secondary outcome measures:
To establish the overall response rate (ORR) in this group
To assess the overall treatment utility of this combination via the use of a comprehensive
health assessment tool.
To evaluate the overall treatment toxicity profile according to the CTC v4.03.
To assess progression free survival in this group
To explore potential VEGF-targeted predictive biomarkers.
