Summary for Patent: 10,261,087
Title:Diagnosis of cancer by detecting auto-antibodies against vascular endothelial growth factor (VEGF)
Abstract: The present invention relates to a method for diagnosis of a cancer, comprising the steps of (i) determining the level of antibodies against vascular endothelial growth factor (VEGF) in a sample from a subject to be diagnosed, (ii) comparing the determined level in the sample to a control level derived from subjects without cancer; wherein a decreased level in the sample from the subject to be diagnosed as compared to the control level is indicative for cancer in the subject. Furthermore, the invention relates to method of predicting response and outcome of a treatment of a cancer with an angiogenesis inhibitor.

Application Number:15/115,902
Patent Claims:1. A method for predicting whether a subject to be treated for ovarian cancer with a drug will respond to said treatment, wherein the drug is a VEGF inhibitor selected from the group consisting of bevacizumab and Aflibercept, or wherein the drug is a platinum analogue, the method comprising (i) determining a level of antibodies against vascular endothelial growth factor (VEGF) (anti-VEGF antibodies) in a sample from said subject to be treated, wherein the anti-VEGF antibodies bind to VEGF-A of SEQ ID NO:1; (ii) comparing the determined level of anti-VEGF antibodies in the sample to either one or both of a first and second VEGF antibody control level, a) wherein the first VEGF antibody control level is determined from subjects not showing relapse or progression of ovarian cancer or mortality within 20 months after onset of treatment with said drug, and b) wherein the second VEGF antibody control level is determined from subjects showing relapse or progression of ovarian cancer or mortality within 20 months after onset of treatment with said drug, wherein a decreased level of anti-VEGF antibodies in the sample from the subject to be treated as compared to the first VEGF antibody control level and/or an equal level as compared to the second VEGF antibody control level is indicative for relapse or progression of ovarian cancer or mortality in the subject within 20 months after onset of treatment with said drug, and wherein an increased level of anti-VEGF antibodies in the sample from the subject to be treated as compared to the second VEGF antibody control level and/or an equal level as compared to the first VEGF antibody control level is indicative for no relapse and no progression of ovarian cancer and no mortality in the subject within 20 months after onset of treatment with said drug.

2. The method according to claim 1, wherein the natural logarithm of a level of antibodies against VEGF in the sample from the subject to be treated of less than 0.9 fold as compared to the natural logarithm of the mean of the first VEGF antibody control level is indicative for relapse or progression of ovarian cancer or mortality in the subject within 20 months after onset of treatment with said drug, and/or the natural logarithm of a level of antibodies against VEGF in the sample from the subject to be treated of more than 1.5 fold as compared to the natural logarithm of the mean of the second VEGF antibody control level is indicative for no relapse and no progression of ovarian cancer and no mortality in the subject within 20 months after onset of treatment with said drug.

3. The method according to claim 1, wherein the drug is bevacizumab, cisplatin or carboplatin.
