Rationale for Anti-VEGF Therapy Vascular leakiness result in decreased flow to some areas of tumor and increased pressure in tumors – Decrease access of drugs, immune cells – Result in hypoxia, which induces tumor progression and decreases efficacy of drugs that require oxygen, and low pH Antiangiogenic therapy targeting VEGF or VEGFR may restore a more normal vasculature, generating an environment less favorable to cancer cell growth Vascular leakiness result in decreased flow to some areas of tumor and increased pressure in tumors – Decrease access of drugs, immune cells – Result in hypoxia, which induces tumor progression and decreases efficacy of drugs that require oxygen, and low pH Antiangiogenic therapy targeting VEGF or VEGFR may restore a more normal vasculature, generating an environment less favorable to cancer cell growth Weinmann M, et al. Onkologie. 2004;27:83-90 [2] ; Goel S, et al. Physiol Rev. 2011;91: [26] Decreased drug delivery (and hence resistance) and increased tumor hypoxia. Another mechanism of antiangiogenic therapy is attenuation of vascular hyperpermeability, increasing vessel pericyte coverage, and normalization of the basement membrane to reduced interstitial fluid pressure and improved blood perfusion. This normalization have consequences on drug and oxygen delivery and on the immune microenvironment
The mechanisms by which anti-VEGF therapy increases survival remain unclear – Anti-VEGF therapy led to a increase in plasma PlGF – High levels of soluble VEGFR1 before starting Bv - worse survival(biomarker of treatment resistance) – Reducing blood flow and permeability improved OS in patients with improved tumor vasculature and blood perfusion after treatment. – Excessive decreasing vascular permeability after Bv therapy negatively impact of combination therapy in NSCLC. – We have to examine the dose effect on tumor vasculature and treatment efficacy.

Summary Bevacizumab plus erlotinib regimens are effective as maintenance treatment for advanced NSCLC in EGFR mutated patients Continuation maintenance therapy with bevacizumab can further extend survival Which is the best sequence of use of this drug? Remains unclear whether bevacizumab’s efficacy is dependent on the chemotherapeutic regimen used. POINTBREAK

..if you don´t have any markers? Ramucirumab Ramucirumab is a human immunoglobulin G, subclass 1 monoclonal antibody that specifically binds to the extracellular domain of VEGF Receptor-2 with high affinity 1 This antibody blocks the binding of the VEGF ligand to VEGF Receptor-2 and inhibits VEGF-stimulated activation 1 Two completed Phase 1 studies of ramucirumab demonstrated safety and tolerability at clinically relevant doses, with preliminary evidence of clinical efficacy across various solid tumors 1,2 Over 3500 patients have been treated with ramucirumab in clinical studies 3 1.Spratlin et al.

A majority of NSCLC patients do not have targetable mutations Second-line treatment options for these patients have historically been limited Important new options for patients without driver mutations who have few effective treatment choices Nintedanib is the only TKI to show a potential OS benefit in the second-line setting Ramucirumab is the first monoclonal antibody to show a survival benefit in the second-line setting (in combination with docetaxel) and the first to benefit patients with disease characterized by squamous histology Careful manegement of side effects will be critical to ensuring that patients maximice treatment benefit Key take-aways
