Study information

Scientific title

Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) assessment of the vascular changes induced with bevacizumab alone and in combination with interferon-alpha in patients with advanced renal cell carcinoma: a phase II, open labelled, randomised, multicentre trial


Study hypothesis

The trial aims to answer:
1. Whether bevacizumab induced changes in DCE-MRI vascular parameters are significantly enhanced by interferon-alpha
2. To establish whether there is an interferon (IFN) dose response in potentiating bevacizumab induced changes in dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) vascular parameters
3. If the DCE-MRI vascular parameter changes correlate to the tumour response, progression free survival and changes of other biomarkers

Ethics approval

National Research Ethics Service, Charing Cross Research Ethics Committee gave approval on the 19th January 2009 (ref: 09/H0711/6)

Study design

Phase II open labelled randomised multicentre trial

Secondary study design

Randomised controlled trial

Trial setting


Trial type


Patient information sheet


Advanced or metastatic renal cell carcinoma


Patients will be randomised to one of the following:
Arm A: Bevacizumab 10 mg/kg every 2 weeks
Arm B: Bevacizumab 10 mg/kg every 2 weeks + interferon alpha 2a (IFN-a2a) 3MU three times per week (t.i.w.)
Arm C: Bevacizumab 10 mg/kg every 2 weeks + IFN-a2a 9 MU t.i.w.

All patients will continue on their randomised treatment regimen until the first tumour assessment at week 8. At this point the decision to introduce or modify the IFN dosage will be at the discretion of the investigator. Treatment with both study drugs will continue until disease progression, unacceptable toxicity, or consent is withdrawn. Patients in all arms will undergo two baseline DCE-MRI scans in the week pre-treatment and then further scans at weeks 2, and 6 weeks post-commencement of bevacizumab. Tumour response will be assessed by RECIST criteria via computed tomography (CT) scans at baseline, 8 weeks and three-monthly thereafter.

Intervention type



Phase II

Drug names

Bevacizumab, interferon alpha 2a

Primary outcome measures

DCE-MRI defined changes in Ktrans after 6 weeks of bevacizumab monotherapy or bevacizumab and low or standard dose IFN-alpha.

Secondary outcome measures

1. Vascular endpoints: intra-arm change in vascular permeability (Ktrans) and tumour hypoxia at 2 and 6 weeks post-commencement of treatment
2. Efficacy endpoints: best overall response, progression free survival, time to progression, measured during follow up analyses
3. Safety endpoints: treatment duration of bevacizumab and IFN, treatment withdrawal, dose modification, incidence of adverse events, measured during follow up analyses
4. Surrogate biomarker analysis: peripheral blood analysis of circulating endothelial cells (CEC), circulating endothelial progenitors (CEP) and proangiogenic monocytic cells; angiogenic factors (e.g. vascular endothelial growth factor [VEGF]) and hypoxia regulated markers, measured during follow up analyses
5. Correlation of DCE-MRI defined changes in Ktrans with clinical response, measured during follow up analyses
6. Correlation of DCE-MRI defined changes in Ktrans with surrogate biomarkers, measured during follow up analyses
7. Analysis of Diffusion MRI and BOLD MRI changes and comparison with other pharmacodynamic markers, measured during follow up analyses

8. Adequate haematological function:
8.1. Absolute neutrophil count (ANC) greater than or equal to 1.5 x 10^9/l, and
8.2. Platelet count greater than or equal to 100 x 10^9/l, and
8.3. Haemoglobin greater than or equal to 8 g/dl (may be transfused to maintain or exceed this level)
9. Adequate liver function:
9.1. Total bilirubin less than 1.5 x upper limit of normal (ULN), and
9.2. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) less than 2.5 x ULN in patients without liver metastases; less than 5 x ULN in patients with liver metastases
10. Adequate renal function:
10.1. Serum creatinine less than or equal to 1.5 x ULN, and
10.2. Urine dipstick for proteinuria less than 2+. Patients discovered to have greater than or equal to 2+ proteinuria on dipstick urinalysis at baseline should undergo a 24-hour urine collection and must demonstrate less than 1 g of protein in 24 hours
11. International normalised ratio (INR) less than or equal to 1.5 within 7 days prior to enrolment. Anticoagulation is allowed if target INR is less than 3 and INR is therapeutic on a stable dose of coumarin-type anticoagulation, or if subject is on a stable dose of low molecular weight (LMW) heparin for greater than 2 weeks at time of enrolment.
12. Women of childbearing age must have a negative pregnancy test and must use adequate contraception during the treatment phase of the study and for 9 months afterwards. Women who wish to breastfeed are not eligible for the study.
