BEP Study Phase I (Bevacizumab, Everolimus, Panitumumab) (BEP)
A Phase I Study of Bevacizumab, Everolimus, and Panitumumab for Patients With Advanced Solid Tumors
Targeting molecular pathways of tumor growth has become a major focus of anti-cancer treatments. This study aims to investigate the toxicity, pharmacokinetics, and preliminary efficacy of the triplet combination of bevacizumab, RAD001, and panitumumab in patients with refractory solid tumors.
This open-labeled, non-randomized phase I trial of bevacizumab, everolimus and panitumumab is designed to assess the safety, tolerability and efficacy of this combination in adult patients with advanced solid tumors.

EGFr inhibition has been shown to have down-regulatory effects on VEGF expression and angiogenesis. The combination of anti-VEGF and anti-EGFr targeting is clinically rational, and preliminarily has shown at least additive, if not synergistic effects [12, 13]. Further, preclinical data has shown that constitutive activation of the AKT pathway is a mechanism of resistance to EGFr inhibitors [14]. Therefore, inhibition of both EGFr and AKT pathways by panitumumab and RAD001 may create a synergistic antitumor effect. There is also rationale that RAD001 and anti-VEGF therapies may be synergistic. Preliminary results from a Phase I dose escalation study of bevacizumab in combination with RAD001 has reported a recommended Phase II dose of this combination, and has described a minor response in a colorectal cancer patient previously refractory to bevacizumab-based therapy, and over 10 months of stable disease in another colorectal cancer patient previous refractory to bevacizumab-based therapy [15].
Bevicizumab (Avatstin) is a humanized monoclonal antibody to VEGF. VEGF is known to play a pivotal role in tumor angiogenesis and is a significant mitogenic stimulus for arterial, venous and lymphatic endothelial cells. The addition of bevacizumab to chemotherapy has been shown to increase overall response rate, duration of response and survival for patients with metastatic colon cancer (4) and is beneficial in first line non-small cell lung cancer and metastatic breast cancer [1, 2], and second line metastatic colorectal cancer (7). VEGF signals through phosphoatidylinositol 3-kinase (PI3K) and Akt as well as through the extracellular regulated kinase (ERK 1/2), a mitogen activated protein kinase (MAPK). VEGF's multiple biologic actions may be mediated by different pathways. Erikkson demonstrated that VEGF induced hyperpermeability was highly dependent on activation of the AKT pathway, while the angiogenic effect was largely unaffected by blocking this pathway and likely depended on ERK activation [3].
RAD001 (Everolimus), an oral derivative of rapamycin, selectively inhibits mTOR (mammalian target of rapamycin), an intracellular protein kinase implicated in the control of cellular proliferation of activated T-lymphocytes or neoplastic cells. mTOR is considered to be a downstream component of the PI3K/AKT/TSC pathway, a signalling module known to be heavily deregulated in many human cancers[4, 5]. In this context, there is an increasing body of evidence suggesting that AKT regulates mTOR activity[5-7], and that the activation status of the PI3K/AKT pathway may be indicative of responsiveness to rapamycins such as RAD001. Specifically, loss of PTEN or constitutive/hyper-activation of AKT has been suggested to sensitize tumors to the effects of inhibition of mTOR[6-8]. Indeed, RAD001 preferentially inhibits the proliferation of tumor cells displaying high AKT activity and totally reverses AKT-driven prostate intraepithelial neoplasia in a mouse transgenic model[7]. Rapamycins also inhibit downstream signaling pathways of VEGF. The rapamycin-regulated PI3K and p70s6 pathways are known to be involved in mediating VEGF's effects on endothelial cells [9]. In animal models, rapamycins modestly decrease tumor VEGF expression, and significantly blunt typical angiogenic responses to VEGF. Everolimus has been shown to inhibit tumor growth and reduce number of blood vessels in a murine melanoma model, indicating that RAD001 has direct antiangiogenic effects [10].
Panitumumab (Vectibix) is a fully humanized monoclonal antibody directed against epidermal growth factor receptor (EGFr), which is a 170-kD transmembrane glycoprotein with a cytoplasmic protein kinase domain essential for tumor growth and division. The receptor binds multiple ligands including epidermal growth factor and transforming growth factor-alpha (TGF-alpha). The tyrosine kinase intracellular domain of the receptor is activated via binding of a ligand to EGFr, which in turn initiates a cascade of intracellular signals. These downstream signaling pathways again include the phosphorylation of mitogen-activated protein kinase (MAPK) through the ras/raf pathway. Inhibition of these signaling pathways can result in cell growth arrest and apoptosis, respectively[11].
