Detailed Description:

Ovarian cancer is diagnosed in approximately 26,000 American women each year, and is the leading cause of death from gynecologic cancers. Difficult to detect, the disease typically presents only when advanced. Ovarian cancer is among the most sensitive of solid tumors to chemotherapy. However, the majority of patients with ovarian cancer who achieve a complete remission with first line platinum-based chemotherapy will ultimately develop recurrent disease. The combination of carboplatin and paclitaxel is the standard first line combination in the US.

In patients with advanced ovarian cancer, carboplatin plus paclitaxel results in less toxicity, is easier to administer, and is not inferior, when compared with cisplatin plus paclitaxel. The randomized trial, GOG-158 finally confirmed the adoption of this standard with an improved toxicity profile of the combination of cisplatin and paclitaxel, a doublet that had been previously demonstrated to have a substantially better progression free and overall survival advantage compared with cisplatin and cyclophosphamide in advanced-stage epithelial ovarian cancer. Although in nonrandomized trials, carboplatin and paclitaxel was a less toxic and highly active combination regimen, there remained concern regarding its efficacy in patients with good prognosis completely resected advanced disease.

In parallel European, multicentre, randomised trials, between January, 1996, and March, 2002, 802 patients with platinum-sensitive ovarian cancer relapsing after 6 months of being treatment-free were enrolled from 119 hospitals in five countries (ICON III). Patients were randomly assigned paclitaxel plus platinum chemotherapy or conventional platinum-based chemotherapy. Survival curves demonstrated a difference in favor of paclitaxel plus platinum (hazard ratio 0.82 [95% CI 0.69-0.97], p=0.02), corresponding to an absolute difference in 2-year survival of 7% between the paclitaxel and conventional treatment groups (57 vs 50% [95% CI for difference 1-12]), and median survival of 5 months (29 vs 24 months [1-11]).

Since the hypothesis of targeting angiogenesis to treat cancer was first described in 1971 by Judah Folkman, there has been intense research into the development of antiangiogenic cancer therapies. Tumors are dependent on their development of a vascular supply. Recent work has shown that, if cells are already transformed, angiogenesis can be initiated with a tumor mass comprising as few as 100-300 cells.

VEGF actions are mediated through binding to two receptor tyrosine kinases, VEGF-R-1 (Flt-1) and VEGF-R- 2 (KDR; whose murine form is known as Flk-1). Activation of these receptors by VEGF triggers the phosphorylation of a multitude of proteins that are active in signal transduction cascades. VEGF gene expression is upregulated by a wide range of stimuli including hypoxia, nitric oxide, estrogen, a variety of growth factors (e.g., FGF-4, PDGF, TNF, TGF-b, EGF, IL-6, IL-1b, #76) and common genetic events associated with the malignant phenotype (loss of tumor suppressor genes such as p53 and activation of oncogenes such as ras, v-src and HER2/neu). Beside major angiogenic properties, VEGF is a potent mitogen for vascular endothelium, inhibits endothelial apoptosis and mobilizes bone marrow-derived endothelial cell precursors. VEGF also mediates the secretion of enzymes involved in the degradation of extracellular matrix, modulates migration, increases vascular permeability, upregulates hexose transport and induces monocyte migration.

Ovarian cancers secrete large amounts of VEGF in vitro and in vivo, and VEGF appears to play a crucial role in angiogenesis and tumor induced immunosuppression in ovarian cancer patients. Indeed, VEGF has been confirmed as an independent prognostic indicator by multivariate analysis of survival.

Angiogenesis is crucial in the development of ovarian cancer. VEGF is closely linked to normal ovarian function and is required for the development of the corpus luteum and the maturation of the endometrium. Elevated VEGF expression occurs in all stages of ovarian cancer and is associated with poor prognosis. In fact, VEGF levels appear to be prognostically important. In addition to its role in ovarian-cancer-associated angiogenesis, VEGF overexpression is directly associated with the production of ascitic fluid, a feature probably related to its ability to induce endothelial hyperpermeability. In studies monitoring VEGF after tumor resection, VEGF appears to be a valid tumor marker, following a dramatic decline after surgery, the levels rise at recurrence.

The parent murine antibody of bevacizumab, A.4.6.1, demonstrated promising antitumor activity in a subcutaneous SKOV-3 human ovarian cancer xenograft model. Interestingly, in the intraperitoneal model of the same cell line, A.4.6.1 produced only partial inhibition of tumor growth, but was associated with almost complete inhibition of ascites production. These data provided the rationale for evaluation of bevacizumab in ovarian cancer. A Gynecologic Oncology Group (GOG) phase II study of bevacizumab monotherapy is ongoing, and a second trial will examine the combination of bevacizumab with daily, low-dose, oral cyclophosphamide, using metronomic dosing in the hope that 'less is more'.

Bevacizumab (rHumAb VEGF; Genentech, Inc., CA), a recombinant humanized monoclonal antibody directed to VEGF, and neutralizes the biological properties of human VEGF. Bevacizumab, derived from the murine antibody A.4.6.1, comprises 93% human IgG frameworks and 7% murine-derived antigen-binding regions, the humanization providing a longer half-life and less immunogenicity.

Based on preclinical data, a phase I/II program with bevacizumab was initiated. The initial phase I trial enrolled 25 patients in a dose-escalation fashion (0.1-10.0 mg/kg on days 0, 28, 35, and 42). No grade 3 or 4 toxicity was seen that was directly attributable to therapy. There were three episodes of tumor-related bleeding, including a hemorrhage in a previously undetected cerebral metastasis. Grade 1 and 2 toxicities, possibly or probably related to treatment, included asthenia, headache, and nausea. There were no complete or partial responses seen, although one patient with renal cell carcinoma achieved a mixed response.

The material use in this study is NOT commercially available Avastin™ (Genentech, Inc.; South San Francisco, CA), and may differ from that product.

Bevacizumab demonstrated preclinical and clinical activity in colorectal cancer and Genentech chose this as the disease for their registration studies. At ASCO 2003 Hurwitz et al reported the results of their phase III study of standard bolus irinotecan/5-FU/LV (IFL) plus bevacizumab (5 mg/kg). An impressive median survival advantage (20.3 months vs. 15.6 months [p=0.00003]) was reported in 925 patients receiving first line therapy with irinotecan, 5-fluorouracil, leucovorin treatment for metastatic colorectal cancer. Only grade 3 hypertension (11%), easily managed with oral medications, was clearly increased in this Phase III study. Gastrointestinal perforation, although rare, was possibly seen more frequently.

Importantly, this was the first phase III validation of an antiangiogenic approach for the treatment of human cancer. Several further, large phase III trials of bevacizumab in metastatic colorectal cancer are under way. These include a first-line study of standard 5-FU/LV with or without bevacizumab in patients who are not appropriate for irinotecan therapy. A further phase III study will assess the FOLFOX regimen with or without bevacizumab in the second-line setting for patients who have failed previous irinotecan plus 5-FU treatment. These results will help to define the benefit of anti-VEGF therapy.

Other studies are awaited, notably ECOG 4599 a randomized comparison of Taxol and carboplatin with and without bevacizumab, in patients with non-small cell lung cancer has completed accrual with over 600 patients.

There are three reasons to investigate protracted exposure to bevacizumab. Firstly, the agent, while inducing apoptosis, is considered a cytotoxic and protracted exposure is thought to be necessary to maintain tumor dormancy. Secondly, the studies in colorectal cancer treated patients until tumor progression. Lastly, there is an evolving paradigm in the treatment of ovarian cancer. It is now widely accepted that continual rather than intermittent palliative chemotherapy translates into a better quality of life. The Gynecologic Oncology Group have recently reported a provocative randomized controlled trial that confirmed a significant and large improvement in progression free survival (GOG 178), considered the most important end point in the patients with advanced ovarian cancer. Furthermore, in the preclinical studies of ovarian cancer, the ovarian cancer model presented a compelling argument for prolonged bevacizumab administration. Having inoculated the human ovarian carcinoma cell line SKOV-3 within the peritoneal cavity of immunodeficient mice, tumor engrafted in 7 to 10 days. The function-blocking VEGF antibody, A4.6.1 significantly inhibited subcutaneous SKOV-3 tumor growth approximately 20 fold compared with controls (P < 0.05), and similarly in the intraperitoneal model. Importantly, within 2 to 3 weeks of cessation of A4.6.1 treatment, effectively treated mice developed severe ascites, became cachectic, and had to be killed, and subsequent tumor burden in these animals varied from moderate to high. It should be clarified that the murine study utilized A4.6.1 the murine precursor of bevacizumab, but that the results can be extrapolated to the actions of bevacizumab.
