Brief summary: The purpose of this study is to test the effectiveness (how well the drug works), safety and tolerability of an investigational drug called nivolumab (also known as BMS-936558) in glioblastoma (a malignant tumor, or GBM), when added to bevacizumab.

Nivolumab is an antibody (a kind of human protein) that is being tested to see if it will allow the body's immune system to work against glioblastoma tumors. Opdivo (nivolumab ) is currently FDA approved in the United States for melanoma (a type of skin cancer), non-small cell lung cancer, renal cell cancer (a type of kidney cancer), Hodgkin's lymphoma but is not approved in glioblastoma. nivolumab may help your immune system detect and attack cancer cells.

Bevacizumab is a drug which works on the blood vessel that supply the tumor and potentially can starve the tumor by cutting off the blood supply to these tumors. Bevacizumab is commercially available and FDA approved for individuals with recurrent glioblastoma.

This study has two study groups. Arm 1 will receive the study drug nivolumab 240mg and bevacizumab 10 mg (standard dose) every 2 weeks and Arm 2 will receive the study drug nivolumab 240 mg and bevacizumab 3 mg (low dose) every 2 weeks. A process will be used to assign participants, by chance, to one of the study groups. Neither participants nor doctors can choose which group participants are in. This is done by chance because no one knows if one study group is better or worse than the other. 90 total participants are expected to participate in this study (45 participants in each arm).

Your total participation in this study from the time you have signed the informed consent to your last visit, including follow-up visits, may be more than three years (depending on what effect the treatment has on your cancer, and how well you tolerate the treatment).

Detailed description: Primary Endpoint(s)

-To evaluate the efficacy of nivolumab when administered with standard and low bevacizumab dosing among recurrent glioblastoma patients as measured by the rate of overall survival at twelve months.

Secondary Endpoint(s)

* To evaluate the safety and tolerability of nivolumab in combination with bevacizumab administered according to standard and low dosage schedules for recurrent glioblastoma patients.
* To compare progression free survival (PFS) at 6 months of nivolumab when administered with standard and low bevacizumab dosing for recurrent glioblastoma patients.
* To compare the overall survival rate of nivolumab when administered with standard and low bevacizumab dosing for recurrent glioblastoma patients.
* To compare progression free survival (PFS) of when administered with standard and low bevacizumab dosing for recurrent glioblastoma patients.
* To compare the objective response rate (ORR) of nivolumab and bevacizumab administered according to standard and low dosage schedules for recurrent glioblastoma patients

Study design and duration: This is a randomized, open-label, phase 2 safety study of nivolumab and bevacizumab administered according to standard and low dosage schedules in adult (≥ 18 years) participants with a first recurrence or second recurrence of glioblastoma (GBM). Participants must have received previous treatment with radiotherapy and one recurrence. The study will allow participants that require decadron up to 4mg/day to participate. Participants will undergo 1:1 randomization to receive treatment with either nivolumab (240 mg flat dosing IV every 2 weeks) and bevacizumab administered according to standard (10 mg/kg IV every 2 weeks; Arm A) and low (3 mg/kg IV every 2 weeks; Arm B) dosage schedules for recurrent glioblastoma participants. The study will allow participants that require decadron up to 4 mg/ day to participate in the study.

Note - In view of the Covid 19 crisis, all in person visits can be substituted for virtual visit. All nursing toxicity checks can be performed over the phone rather than in person

* Men who are sexually active with WOCBP must use contraceptive method such as male condom with spermicide. Men receiving nivolumab and who are sexually active with WOCBP will be instructed to adhere to contraception for the duration of treatment with study drug (s) plus 5 half-lives of study drug (s) plus 90 days (duration of sperm turnover) for a total of 31 weeks post-treatment completion.
* Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile as well as azoospermic men) do not require contraception.
* Azoospermic males and WOCBP who are continuously not heterosexually active are exempt from contraceptive requirements.
* Investigators shall counsel WOCBP and male subjects who are sexually active with WOCBP on the importance of pregnancy prevention and the implications of an unexpected pregnancy. Investigators shall advise WOCBP and male subjects who are sexually active with WOCBP on the use of highly effective methods of contraception. Highly effective methods of contraception have a failure rate of \< 1% per year when used consistently and correctly.
* At a minimum, subjects must agree to the use of two methods of contraception, with one method being highly effective and the other method being either highly effective or less effective as listed below:
* HIGHLY EFFECTIVE METHODS OF CONTRACEPTION

  * Hormonal methods of contraception including combined oral contraceptive pills, vaginal ring, injectables, implants, and intrauterine devices (IUDs) such as Mirena® by WOCBP subjects or male subject's WOCBP partner.
  * Nonhormonal IUDs, such as ParaGard
  * Tubal ligation
  * Vasectomy.
  * Complete Abstinence\* ---\*Complete abstinence is defined as complete avoidance of heterosexual intercourse and is an acceptable form of contraception for all study drugs. Subjects who choose complete abstinence are not required to use a second method of contraception, but female subjects must continue to have pregnancy tests. Acceptable alternate methods of highly effective contraception must be discussed in the event that the subject chooses to forego complete abstinence.
* LESS EFFECTIVE METHODS OF CONTRACEPTION

  * Diaphragm with spermicide
  * Cervical cap with spermicide
  * Vaginal sponge
  * Male Condom without spermicide\*
  * Progestin only pills by WOCBP subjects or male subject's WOCBP partner
  * Female Condom\* ---\*A male and female condom must not be used together
* Women of Child Bearing Potential (WOCBP)

  --A women of childbearing potential (WOCBP) is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) and is not postmenopausal. Menopause is defined as 12 months of amenorrhea in a woman over age 45 years in the absence of other biological or physiological causes. In addition, women under the age of 55 years must have a serum follicle stimulating hormone, (FSH) level \> 40mIU/mL to confirm menopause.\*

  ---\*Women treated with hormone replacement therapy, (HRT) are likely to have artificially suppressed FSH levels and may require a washout period in order to obtain a physiologic FSH level. The duration of the washout period is a function of the type of HRT used. The duration of the washout period below are suggested guidelines and the investigators should use their judgment in checking serum FSH levels. If the serum FSH level is \> 40 mIU/ml at any time during the washout period, the woman can be considered postmenopausal:
  * 1 week minimum for vaginal hormonal products (rings, creams, gels)
  * 4 week minimum for transdermal products
  * 8 week minimum for oral products
* Other parenteral products may require washout periods as long as 6 months Each of the criteria in the checklist that follows must be met in order for a patient to be considered eligible for this study. Use the checklist to confirm a patient's eligibility. The checklist must be completed for each patient and must be signed and dated by the treating physician.
