1 Bevacizumab (Avastin) in combination with non-taxanes for metastatic breast cancer - first line therapy December 2007 This technology summary is based on information available at the time of research and a limited literature search. It is not intended to be a definitive statement on the safety, efficacy or effectiveness of the health technology covered and should not be used for commercial purposes.

2 Bevacizumab (Avastin) in combination with non-taxanes for metastatic breast cancer - first line therapy Target group Breast cancer - metastatic (stage IV), first line in combination with non-taxane chemotherapy Technology description Bevacizumab (Avastin) is a humanised anti-vascular endothelial growth factor (VEGF) monoclonal antibody that inhibits VEGF-induced signalling and inhibits VEGF-driven angiogenesis. This reduces vascularisation of tumours, thereby inhibiting tumour growth. Bevacizumab is administered as a 10mg/kg short intravenous infusion every 2 weeks, or as a 15mg/kg infusion every 3 weeks until disease progression (in excess of 9 months). Non-taxane chemotherapy combinations include anthracycline-based (doxorubicin or epirubicin) regimens or capecitabine (Xeloda). Bevacizumab is currently licensed for: Metastatic breast cancer: first line treatment in combination with paclitaxel. Metastatic colorectal cancer: in combination with cytotoxic chemotherapy. Non-small cell lung cancer (unresectable advanced, metastatic or recurrent): first line treatment in combination with platinum-based therapy. Advanced and/or metastatic renal cell cancer: first-line in combination with interferon alfa-2a. Innovation and/or advantages Bevacizumab may prolong disease-free progression and improve overall survival in this patient group. It would also provide another treatment option for people with metastatic breast cancer. Developer Roche Products Ltd. Place of use Home care e.g. home dialysis Secondary care e.g. general, non-specialist hospital General public e.g. over the counter Community or residential care e.g. district nurses, physio Tertiary care e.g. highly specialist services or hospital Other: Primary care e.g. used by GPs or practice nurses Emergency care e.g. paramedic services, trauma care Availability, launch or marketing dates, and licensing plans: Bevaciumab in combination with non-taxanes is in phase III clinical trials for first line therapy for metastatic breast cancer. NHS or Government priority area: This topic is relevant to the NHS Cancer Plan Relevant guidance NICE clinical guidelines in progress (due January 2009): o Advanced breast cancer diagnosis and treatment 2

3 o Early breast cancer diagnosis and treatment SIGN clinical guideline. Management of breast cancer in women, NICE cancer service guidance - Improving outcomes in breast cancer, NICE Technology Appraisals (in development) Bevacizumab for the treatment of advanced or metastatic breast cancer (with taxane-based chemotherapy). Expected publication date July Lapatinib for the treatment of advanced or metastatic breast cancer. Publication date to be announced. NICE Technology Appraisals (published) Advanced breast cancer: trastuzumab ( ), taxanes (docetaxel and paclitaxel, ), vinorelbine ( ), gemcitabine ( ) and capecitabine ( ). Early stage breast cancer: adjuvant hormonal therapies ( ), and for adjuvant treatment - trastuzumab ( ), docetaxel ( ) and paclitaxel ( ). Clinical need and burden of disease Breast cancer is the most common malignancy affecting women in the UK. There were 39,301 women newly diagnosed with breast cancer in England and Wales during and in 2005 there were 10,969 deaths, a rate of 40 deaths per 100,000 females 13. Between 16% and 20% of women (an estimated 6,288 to 7,860 women) presenting with breast cancer have advanced disease with distant metastases 3, and in 2002 NICE estimated that around 50% of those presenting with early or localised breast cancer will eventually develop metastatic breast cancer 3. Existing comparators and treatments The role of current treatments for advanced and metastatic breast cancer is to palliate symptoms, prolong survival and maintain a good quality of life. The choice of treatment is based on previous therapy, oestrogen receptor status, HER2 status and the extent of the disease. Current options include: First line systemic therapy for oestrogen receptor-negative disease is chemotherapy (usually an anthracycline based regimen a or a combination of cyclophosphamide, methotrexate and fluorouracil). Hormone manipulation therapy for oestrogen receptor positive tumours. Following disease progression on an anthracycline, other chemotherapy options include single-agent taxanes, capecitabine (in combination with docetaxel or as monotherapy), bevacizumab (in combination with paclitaxel), vinorelbine and gemcitabine in combination with paclitaxel. Trastuzumab in combination with taxanes is given to those with HER2+ metastatic disease. It may also be given on its own in women with advanced breast cancer who have already received at least two courses of chemotherapy 14. A large proportion of women who develop metastatic breast cancer may be unsuitable for anthracycline therapy due to the risk of cumulative cardiotoxicity from the use of these agents in the adjuvant setting. a Anthracycline based regimens include AC (doxorubicin and cyclophosphamide), EC (epirubicin and cyclophosphamide), CAF (cyclophosphamide, doxorubicin and fluorouracil), FEC (fluorouracil, epirubicin and cyclophosphamide) 3

Received capecitabine 1000mg/m 2 twice daily on days 1-14 (28 doses) and bevacizumab 15mg/kg on day 1. Treatment repeated every 21 days until progression. Median follow up 12.9 months (range ) Time to Progression (TTP) Overall survival (OS); overall response rate (ORR), median response rate; response duration, time to failure. Key results Average no. cycles received 6.8. Median TTP 5.7 months ( ) in 106 intent-to-treat patients. Oestrogen-receptor positive subgroup had median delay of 8.9 months. Clinical benefit observed in 81.4% - ORR = 38.5% (complete response =5.5%; partial response =33.0%); stable disease in 42.9%. 84 pts alive at study end. Median OS 16+ months (95% CI: not reached). Expected reporting Adverse effects Majority of adverse events (AEs) were mild or moderate. Most common grade 3 AEs were hand-foot syndrome (13%) and pain (10%); grade 4 pulmonary embolism occurred in 4%. Of 24 deaths, 2 were treatment-related. n=1200; previously untreated metastatic breast cancer (HER2-negative). Received bevacizumab (15mg/kg every 3 weeks) in combination with any one of 3 chemotherapy agents: taxanes, anthracyclines, or capecitabine vs. chemotherapy alone. Progression free survival (PFS) Objective response; one-year survival rate; OS. - Patient recruitment completed Q Efficacy data anticipated Q Estimated cost and cost impact For an average person of 67.5kg, the cost of a dose of bevacizumab will be approximately 1,650 at 10mg/kg, or 2,570 at 15mg/kg (assuming wastage) b. The estimated minimum 9-month treatment course would cost in the region of 33,000 c. This will be in addition to the cost of standard non-taxane chemotherapy regimens. b Costs from BNF 54. September c Based on calendar weeks 4

5 Bevacizumab will be administered during the same hospital visit as the other chemotherapy drugs in the combined regimen. Potential or intended impact speculative Patients Reduced morbidity Quicker, earlier or more accurate diagnosis or identification of disease Reduced mortality or increased survival Other: Improved quality of life for patients and/or carers Non identified Services Increased use Service reorganisation required Staff or training required Decreased use Other: Non identified Costs Increased unit cost compared to alternative Increased costs: more patients coming for treatment New costs: additional therapy Savings: Other: Increased costs: capital investment needed References 1 Management of breast cancer in women.
