Phase III trial of Avastin plus chemotherapy showed 30 percent improvement in overall survival in first-line non-squamous, non-small cell lung cancer
First phase III study to extend median survival beyond one year in advanced lung cancer
Roche and Genentech announced on Friday that data from a phase III study (E4599) of Avastin (bevacizumab) plus paclitaxel and carboplatin chemotherapies in first-line non-squamous, non-small cell lung cancer (NSCLC) showed the study met its primary efficacy endpoint of improving overall survival. Results from an interim analysis of this study showed that patients receiving Avastin plus paclitaxel and carboplatin had a 30 percent improvement in overall survival (or a hazard ratio of 0.77, which can also be referred to as a 23 percent reduction in the risk of death), compared to patients who received chemotherapy alone. This study showed that median survival of patients treated with Avastin plus chemotherapy was 12.5 months compared to 10.2 months for patients treated with chemotherapy alone.
These data were featured in a press briefing at the 41st Annual Meeting of the American Society of Clinical Oncology (ASCO). More detailed presentations of the data was made during a plenary session by Alan B. Sandler, M.D., of Vanderbilt University Medical Center in Nashville (Abstract #LBA4).
“The results of this phase III study reveal, for the first time, an improvement in survival with the addition of a targeted biologic agent to standard chemotherapy in this patient population, and the first time median survival has been extended beyond one year in advanced lung cancer,” said Dr. Sandler. “We also observed improvements in other measures of patient benefit, including progression-free survival and tumor response rate.”
This study showed a 61 percent improvement in progression-free survival (or a hazard ratio of 0.62, which can also be referred to as a 38 percent reduction in the risk of progression). Median progression-free survival was 6.4 months for patients treated with Avastin plus chemotherapy, compared to 4.5 months for patients treated with chemotherapy alone. The response rate in patients with measurable disease was 27 percent (97/357) in the group receiving Avastin plus chemotherapy, compared to 10 percent (35/350) in the group receiving chemotherapy alone.
In previous clinical experience with Avastin in combination with paclitaxel and carboplatin in NSCLC, patients with a specific type of NSCLC called squamous cell carcinoma had a higher risk of experiencing life-threatening or fatal pulmonary bleeding. These patients were excluded from this Phase III study and the rate of life-threatening or fatal pulmonary bleeding in patients treated with Avastin was substantially reduced from prior clinical studies. A preliminary assessment of adverse events by the investigators showed that Grade 3/4/5 bleeding occurred in 4.5 percent of patients in the Avastin plus chemotherapy arm, compared to 1 percent of patients in the chemotherapy alone arm. Treatment-related deaths occurred at a rate of 2 percent (8/420) in the Avastin plus chemotherapy arm, compared to less than 1 percent (2/427) in the chemotherapy alone arm. Fatal (Grade 5) haemoptysis occurred at a rate of 1 percent (5/420) in the Avastin plus chemotherapy arm.
The preliminary safety assessment showed that the most common adverse events were neutropenia, hypertension and thrombotic events. Grade 3/4 neutropenia occurred in 24 percent of patients treated with Avastin plus chemotherapy and 16 percent of patients who received chemotherapy alone. Hypertension occurred in 6 percent of patients who received Avastin plus chemotherapy and 1 percent of patients who received chemotherapy alone. Grade 3/4 venous thrombosis occurred in 4 percent of patients treated with Avastin plus chemotherapy, compared with 3 percent of patients treated with chemotherapy alone. Grade 3/4 arterial thrombosis occurred in 2 percent of patients treated with Avastin plus chemotherapy, compared with 1 percent in patients treated with chemotherapy alone.
“Data from this study show that Avastin may have the potential to become an important new treatment option for patients diagnosed with non-small cell lung cancer,” said Kapil Dhingra, M.D., Roche’s Vice President, Oncology. “We plan to share the data with the regulatory authorities in order to discuss the next steps for registering Avastin for first-line treatment of NSCLC.”
About the trial design
The trial was sponsored by the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), under a Cooperative Research and Development Agreement between NCI and Genentech, Inc., and conducted by a network of researchers led by the Eastern Cooperative Oncology Group (ECOG).
This is the first phase III study to evaluate the therapeutic antibody Avastin in combination with chemotherapy in NSCLC. This was a randomized, controlled, multicenter trial that enrolled 878 patients with previously-untreated advanced NSCLC. The patients enrolled in this trial were randomized to receive treatment with paclitaxel and carboplatin chemotherapies with or without Avastin.
About Avastin
Avastin is the first treatment that inhibits angiogenesis – the growth of a network of blood vessels that supply nutrients and oxygen to cancerous tissues. Avastin targets a naturally occurring protein called VEGF (Vascular Endothelial Growth Factor), a key mediator of angiogenesis, thus choking off the blood supply that is essential for the growth of the tumour and its spread throughout the body (metastasis).
In Europe, Avastin is approved for first-line treatment of patients with metastatic carcinoma of the colon or rectum in combination with the chemotherapy regimens of intravenous 5-fluorouracil/folinic acid or intravenous 5-fluorouracil/folinic acid/irinotecan. Avastin received fast-track approval by the US Food and Drug Administration (FDA) and was launched in the US in February 2004. In the US, Avastin is approved for use in combination with intravenous 5-fluorouracil-based chemotherapy, for first-line treatment of patients with metastatic carcinoma of the colon or rectum.
Roche and Genentech are pursuing a comprehensive clinical programme investigating the use of Avastin in advanced colorectal cancer with other chemotherapies and also expanding into the adjuvant setting (post operation). As its mechanism may be relevant in a number of malignant tumours, Roche and Genentech are also investigating the potential clinical benefit of Avastin in pancreatic cancer, ovarian cancer, renal cell carcinoma and others. Approximately 15,000 patients are expected to be enrolled into clinical trials over the next years worldwide.
About Non-Small Cell Lung Cancer
According to the World Health Organization, there are more than 1.2 million cases worldwide of lung and bronchial cancer each year, causing approximately 1.1 million deaths annually. The drug treated prevalence for non-small cell lung cancer is approximately 175,000 patients, of which an estimated 138,000 patients are stage IIIB/IV. Up to 25 percent of stage IIIb/IV non-small cell lung cancer patients may be ineligible for treatment with Avastin. According to the National Cancer Institute, lung cancer is the single largest cause of cancer deaths in the United States and is responsible for nearly 30 percent of cancer deaths in this country. NSCLC is the most common form of the disease and accounts for almost 80 percent of all lung cancers.
