"Bavituximab"

Bavituximab decreases immunosuppressive myeloid-derived suppressor cells in newly diagnosed glioblastoma patients. We evaluated the efficacy of bavituximab - a monoclonal antibody with anti-angiogenic and immunomodulatory properties - in newly diagnosed glioblastoma (GBM) patients who also received radiation and temozolomide. Perfusion MRI and myeloid-related gene transcription and inflammatory infiltrates in pre-and post-treatment tumor specimens were studied to evaluate on-target effects (NCT03139916). Thirty-three adults with isocitrate-dehydrogenase-wild-type GBM received 6 weeks of concurrent chemoradiation, followed by 6 cycles of temozolomide (C1-C6). Bavituximab was given weekly, starting week 1 of chemoradiation, for at least 18 weeks. The primary endpoint was proportion of patients alive

Bavituximab for advanced non-small cell lung cancer - second line in combination with docetaxel Bavituximab for advanced non-small cell lung cancer – second line in combination with docetaxel ..

Randomized phase 3 study of docetaxel plus bavituximab in previously treated advanced non-squamous non-small-cell lung cancer. Bavituximab is a monoclonal antibody that targets phosphatidylserine in the presence of β2 glycoprotein 1 (β2GP1) to exert an antitumor immune response. This phase III trial determined the efficacy of bavituximab combined with docetaxel in patients with previously of clinically significant bleeding. Eligible patients were randomized 1 : 1 to receive up to six 21-day cycles of docetaxel plus either weekly bavituximab 3 mg/kg or placebo until progression or toxicity. The primary end point was overall survival (OS). A total of 597 patients were enrolled. Median OS was 10.5 months in the docetaxel + bavituximab arm and was 10.9 months in the docetaxel + placebo arm (HR

Docetaxel Combined With Bavituximab in Previously Treated, Advanced Nonsquamous Non-Small-Cell Lung Cancer. Bavituximab is a phosphatidylserine-targeting antibody with a selective tumor, vascular-directed immune response. In this phase II trial the efficacy and safety of bavituximab combined with docetaxel for previously treated, advanced nonsquamous non-small-cell lung cancer were evaluated . Patients were randomized 1:1:1 to receive docetaxel 75 mg/m(2) every 21 days for up to 6 cycles combined with weekly, blinded infusions of placebo, bavituximab 1 mg/kg, or bavituximab 3 mg/kg until disease progression or unacceptable toxicity. The primary end point was overall response rate (ORR), with a predefined end point of 26% in the bavituximab arms. After study unblinding, vial-coding

Profile of bavituximab and its potential in the treatment of non-small-cell lung cancer. Bavituximab is a an unconjugated, chimeric immunoglobulin G1 (IgG1) monoclonal antibody directed against the phosphatidylserine (PS) expressed on tumor endothelium, with a specific mechanism of action. PS is an anionic membrane phospholipid, physiologically restricted to the internal membrane leaflet; various pathophysiologic processes cause the exposure of PS on the external membrane leaflet. Bavituximab, once bound, starts up host effector activities, such as antibody dependent cellular cytotoxicity, causing vessel destruction and enhancing antitumor immunity. Phase I clinical trials of bavituximab administered as monotherapy or in combination with other chemotherapeutic agents in adults with pretreated solid

Study of Bavituximab, Axitinib, and Avelumab in Advanced Hepatocellular Carcinoma Across cancer types, immune checkpoint inhibitors have been shown to induce complete response, partial response, and stable disease after initial evidence of radiographic increase in tumor burden. Treatment beyond progression should be considered when the patient is stable (or improving) symptomatically and if tumor anti-tumor immunity.Given the complimentary immune augmenting mechanisms of targeting VEGF and phosphatidylserine, combination axitinib, bavituximab, and avelumab, a PD-L1 antibody, represents a novel and rational immunotherapy regimen in HCC.

An Open Label Study of Bavituximab and Pembrolizumab in Advanced Gastric and GEJ Cancer Patients This study evaluates the combination of bavituximab and pembrolizumab in the treatment of gastric and gastroesphogeal cancer. All patients will receive both bavituximab, a drug that is not yet approved by the FDA, and pembrolizumab known as Keytruda.There is no expanded access program available

1922GCCC: Pembro and Bavituximab for Squamous Cell Carcinoma of Head and Neck This phase II single arm study is being done to determine if bavituximab could potentially synergize with PD-1 inhibitor therapy to generate an effective anti-tumor immune response in patients with recurrent/metastatic squamous cell head and neck cancer (HNSCC) who progressed on a PD-1 inhibitor. The goal of this study is to assess whether treatment with bavituximab shifts the cellular balance to favor an effective T-cell mediated antitumor response resulting to an enhanced response in conjunction with pembrolizumab. Bavituximab is a chimeric (human/mouse) monoclonal antibody that targets phosphatidylserine (PS). PS facilitates the recognition and clearance of dying cells, triggering the release of immunosuppressive

-dependent flippase activity. Cancer cell lines with high surface PS have low flippase activity and high intracellular calcium content. Human Annexin-V, PS targeting antibodies (PGN635 and bavituximab and mch1N11), lysosomal protein, phospholipid Saposin C dioleoylphosphatidylserine (SapC-DOPS), peptide-peptoid hybrid PPS1, PS-binding 14-mer peptide (PSBP-6) and hexapeptide (E3) have been reported

on the inner leaflet of the plasma membrane facing the cytosol. Following viral infection, activation or pre-apoptotic changes cause PS to become externalized. We have previously shown that bavituximab, a chimeric human-mouse antibody that binds PS complexed with β2-glycoprotein I (β2GP1), protected rodents against lethal Pichinde virus and cytomegalovirus infections. Here, we determined the antiviral

of M2 macrophages, while increasing the apoptotic index of tumor endothelial cells and the frequency of M1 macrophages. Furthermore, we report the findings of a Phase I clinical study of bavituximab, a chimeric version of 2aG4, combined with sorafenib in HCC patients. The Phase I results demonstrate the appropriate dose of bavituximab to be given with sorafenib in future clinical trials. Overall , these results strongly support the combination of bavituximab with sorafenib as a promising systemic therapeutic strategy for the treatment for advanced HCC patients.

Antiphosphatidylserine Antibody Combined with Irradiation Damages Tumor Blood Vessels and Induces Tumor Immunity in a Rat Model of Glioblastoma. The vascular targeting antibody bavituximab is being combined with chemotherapy in clinical trials in cancer patients. Bavituximab targets the membrane phospholipid, phosphatidylserine, complexed with beta2-glycoprotein I. Phosphatidylserine is normally intracellular but becomes exposed on the luminal surface of vascular endothelium in tumors. Phosphatidylserine exposure on tumor vessels is increased by chemotherapy and irradiation. Here, we determined whether treatment with the murine equivalent of bavituximab, 2aG4, combined with irradiation can suppress tumor growth in a rat model of glioblastoma. F98 glioma cells were injected into the brains

'-dependent manner. These results suggest that 2aG4 enhances the antitumor effects of radiation therapy by increasing antibody-dependent cell-mediated cytotoxicity toward tumor vessels with externalized phosphatidylserine. Bavituximab, a chimeric version of 2aG4 in clinical trials, has the potential to enhance the therapeutic efficacy of radiation therapy in lung cancer patients.

the hypothesis that a chimeric monoclonal antibody that binds phosphatidylserine could be labeled with radioactive arsenic isotopes and used for molecular imaging of solid tumors in rats. Bavituximab was labeled with (74)As (beta(+), T(1/2) 17.8 days) or (77)As (beta(-), T(1/2) 1.6 days) using a novel procedure. The radionuclides of arsenic were selected because their long half-lives are consistent localization of bavituximab to the tumors. The tumor-to-liver ratio 72 h after injection was 22 for bavituximab compared with 1.5 for an isotype-matched control chimeric antibody of irrelevant specificity. Immunohistochemical studies showed that the bavituximab was labeling the tumor vascular endothelium. These results show that radioarsenic-labeled bavituximab has potential as a new tool for imaging
