Expression profiling of mouse liver after treatment with Vascular Endothelial Growth Factor (VEGF) inhibitor aflibercept

Project description:Transcriptional profiling of mouse liver was compared between VEGF inhibitor aflibercept and control treatment after 9 weeks. 8-10 week-old SCID mice received VEGF Trap protein (aflibercept) subcutaneously twice per week at 25mg per kg body weight for 9 weeks. For control groups, mice were treated with humanized Fc (Regeneron). 5 biological replicates were performed for the control group and 4 biological replicates were performed for the treatment group

Folfiri-Aflibercept vs. Folfiri-Bevacizumab as Second Line Treatment of RAS Mutated Metastatic Colorectal Cancer in Real Practice.

Project description:Background: There are no clinical studies comparing the efficacy of bevacizumab vs.aflibercept in association with folfiri in RAS mutated (RAS-M) metastatic colorectal cancer patients (mCRC) pretreated with folfox and bevacizumab. Patients and Methods: Consecutive RAS-M unresectable mCRC patients progressing to first-line folfox/bevacizumab were treated with 12 cycles of folfiri/bevacizumab (arm A) or folfiri/aflibercept (arm B) at Oncologist discretion. Differences in overall survival between the two schedules were analyzed. Responses and toxicities were described with RECIST and NCI-CTC v4.0, respectively. Results: Seventy-four patients were treated from January 2014 to January 2018; 31 with arm A, 43 with arm B. Among clinical factors there was a predominance of more extended disease (>2 metastatic sites) in arm B (26/43 [60.5%] vs. 10/31 [32.2%] arm A; p = 0.0414). Fifty-nine patients were evaluable for response: arm A, 5 PR (Partial Response), 15 SD (Stable Disease), 8 PD (Progressive Disease); arm B, 5 PR, 16 SD, 10 PD. There were no grade 4 toxic events. Duration of first-line chemotherapy was significantly shorter in patients treated in arm B (12 pts <6 months, 16 pts ≥6, and <12, 15 pts ≥12) vs. arm A (1 pts <6 months, 14 pts ≥6, and <12, 16 pts ≥12) (p = 0.0210); these patients were excluded from survival analysis to avoid prognostic interferences. No maintenance treatment with aflibercept was done in arm B while in arm A bevacizumab with or without fluorouracil and folinic acid were allowed. Median OS were 8.9 months in arm A vs. 12.1 months in arm B (+3.2 months; p = 0.9331, HR: 1.02; 95% CI: 0.57-1.84). Six-months survivals were 65% in arm A and 80% in arm B. Conclusions: Folfiri/bevacizumab and folfiri/aflibercept are equally effective second-line therapies in RAS-M mCRC patients. Although not significant, folfiri/aflibercept was associated with a lower risk of death particularly during the 6-months induction phase.

Differences in Aqueous Humor Protein Profiles in Patients With Proliferative Diabetic Retinopathy Before and After Aflibercept Treatment

Project description:To investigate the changes in aqueous humor (AH) protein profiles before and after intravitreal aflibercept (IVA) treatment in patients with proliferative diabetic retinopathy (PDR) patients. 5 PDR patients provided 10 samples of AH before and after IVA treatment (pre-group vs post-group). Proteins were identified using liquid chromatography-tandem mass spectrometry. Then, bioinformatics was employed to investigate the functional significance of differentially expressed proteins (DEPs) and hub proteins.

Effects of Aflibercept administration at 25 mg per kg body weight in retinas of mice subjected to the oxygen-induced retinopathy protocol

Project description:We aimed at identifying the regulatory network of Aflibercept in the context of pathological neovascularization by using the oxygen-induced retinopathy mouse model as a surrogate of proliferative diabetic retinopathy Total RNA was collected from entire retinal cups dissected from mice subjected to the oxygen-induced retinopathy protocol and subsequently injected with Aflibercept either on postnatal day 13 (collection on day 14) or on postnatal day 13 and 15 (collection on day 17). Non-injected OIR littermates and age-matched mice housed in normoxic conditions were used as controls.

Effects of Aflibercept administration at 25 mg per kg body weight in retinas of mice subjected to the oxygen-induced retinopathy protocol [P19]

Project description:We aimed at identifying the regulatory network of Aflibercept in the context of pathological neovascularization by using the oxygen-induced retinopathy mouse model as a surrogate of proliferative diabetic retinopathy Total RNA was collected from entire retinal cups dissected from 19-days old mice subjected to the oxygen-induced retinopathy protocol and subsequently injected with Aflibercept either on postnatal days 13 and 15 (OIR+AFLx2) or on postnatal days 13, 15 and 17. Non-injected OIR littermates (OIR) and age-matched mice housed in normoxic conditions (normoxia) were used as controls.

Project description:We aimed at identifying the regulatory network of Aflibercept in the context of pathological neovascularization by using the oxygen-induced retinopathy mouse model as a surrogate of proliferative diabetic retinopathy Total RNA was collected from entire retinal cups dissected from 50-days old mice subjected to the oxygen-induced retinopathy protocol and subsequently injected with Aflibercept either on postnatal days 13 and 15 (OIR+AFLx2) or on postnatal days 13, 15 and 17. Non-injected OIR littermates (OIR) and age-matched mice housed in normoxic conditions (normoxia) were used as controls.

Study of Aflibercept as Maintenance Therapy Following Induction With Aflibercept in Combination With XELOX, as First-Line Treatment for Metastatic Colorectal Cancer Patient

Project description:Primary Objectives: Study Part 1: To determine the recommended dose for the aflibercept, oxaliplatin and capecitabine (XELOX) combination to be used in the Part 2 of the study. Study Part 2: To assess the percentage of participants without progression of the disease at 6 months after the start of maintenance therapy with aflibercept single-agent, following the first-line induction therapy with XELOX and aflibercept combination in participants with previously untreated metastatic colorectal cancer. Secondary Objective: Study Part 2: Include the evaluation of progression free survival, overall survival, response to treatment, the overall safety (during induction and maintenance therapy) and the assessment of aflibercept pharmacodynamics and biomarkers parameters.
