Inclusion Criteria: * Participants must have histologically confirmed newly diagnosed glioblastoma or glioblastoma variant (ex. gliosarcoma), including documentation of unmutated isocitrate dehydrogenase (IDH) by immunohistochemistry (sequencing not required). * Participants must have 1-4 cm2 measurable disease (4 cm2 is the maximal size). See Section 11 for the evaluation of measurable disease. Disseminated GBM is not allowed. * No prior immunotherapy allowed or prior alkylating agents or prior radiation to the brain. * Age \>17 years since adult GBM is biologically different from pediatric GBM and there is no data for bavituximab in pediatric populations. * Karnofsky ≥60%, see Appendix A * Life expectancy of greater than 6 months. * Participants must have normal organ and marrow function as defined below: * leukocytes ≥3,000/mcL * absolute neutrophil count ≥1,500/mcL * platelets ≥100,000/mcL * total bilirubin within normal institutional limits (unless patient has Gilbert's syndrome in which total bilirubin should be ≤ 2xULN) * AST(SGOT)/ALT(SGPT) ≤2.5 × institutional upper limit of normal * creatinine within normal institutional limits OR * creatinine clearance ≥60 mL/min/1.73 m2 for participants with creatinine levels above institutional normal(using Cockcroft Gault Formula) * negative serum pregnancy test in WOCBP * INR/PT ≤1.5 x institutional ULN unless subject is receiving anticoagulant therapy as long as PT or INR is within therapeutic range of intended use of anticoagulants * aPTT ≤1.5 x institutional ULN unless subject is receiving anticoagulant therapy as long as PTT is within therapeutic range of intended use of anticoagulants * \< 4 mg dexamethasone daily (or equivalent if on another corticosteroid) at time of start of therapy. Patients on a steroid taper post-surgery and are anticipated to be on \<4 mg at time of chemoradiation initiation will be eligible to consent but to initiate treatment on trial, the participant must be on \<4 mg or equivalent of steroids otherwise participate will be deemed a screen fail and be replaced. * The effects of bavituximab on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of bavituximab administration. * Able to undergo an MRI scan and receive gadolinium-based contrast. * 1 cm3 of available tissue. * Ability to understand and the willingness to sign a written informed consent document Exclusion Criteria: * Participants who are receiving any other investigational agents. * History of allergic reactions attributed to compounds of similar chemical or biologic composition to bavituximab. * Participants receiving any medications or substances that are moderate and/or potent enzyme inducers or inhibitors which may have an effect on the metabolism of bavituximab. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product (Appendix C for partial list). * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. * Pregnant women are excluded from this study because bavituximab is an immunotherapy agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with bavituximab breastfeeding should be discontinued if the mother is treated with bavituximab. These potential risks may also apply to other agents used in this study. * HIV-positive participants on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with bavituximab. In addition, these participants are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in participants receiving combination antiretroviral therapy when indicated. * Participants with other active malignancy in the past 3 years excluding in situ tumors. * Participants must meet the following windows from procedures (there is no window required for port placement since there is no anticipated impact on wound healing with bavituximab): * Major surgery (ex. craniotomy) within 3 weeks of initiation of treatment. * Brain biopsy within 2 weeks * Participants with history of bleeding disorder/coagulopathy. * Participants with history of chronic or acute hepatitis C or B infection
