Brief Summary:
This is a phase II study of the combination of the GITR agonist monoclonal antibody INCAGN01876, the anti-PD1 monoclonal antibody INCMGA00012, and stereotactic radiosurgery (SRS) for recurrent Glioblastoma (GBM). The investigators hypothesize that the proposed regimen will be safe and stimulate a robust anti-tumor immune response and result in improved tumor responses.

Condition or disease Intervention/treatment Phase
Glioblastoma Drug: INCMGA00012 Drug: INCAGN01876 Drug: SRS Procedure: Brain surgery Phase 2

Detailed Description:

The study has 2 arms:

Arm A (Cohort A) is a nonsurgical arm (N=16) that will serve as the primary study cohort and evaluated for the primary study endpoint. Subjects in this arm receive a single priming dose of both INCMGA00012 and INCAGN01876 prior to stereotactic radiosurgery (SRS), then undergo SRS (8 Gy x 3 fractions). Following SRS, INCMGA00012 (IV every 4 weeks) and INCAGN01876 (IV every 2 weeks) are resumed and continued until disease progression, unacceptable toxicity, or for 2 years, whichever occurs first.

Arm B (Cohort B) is a surgical arm (N=16) that will allow for evaluation of the effects on the tumor immune microenvironment of INCMGA00012, INCAGN01876, and SRS. In order to be enrolled on this arm, subjects must have a clinical indication for surgical resection of the recurrent GBM tumor. Prior to planned surgical resection, subjects receive neoadjuvant immunotherapy (one of two possible combinations, as outlined below). Subjects then undergo surgery. Postoperatively, the immunotherapy combination of INCMGA00012 (IV every 4 weeks) and INCAGN01876 (IV every 2 weeks) is resumed and continued until disease progression, unacceptable toxicity, or for 2 years, whichever occurs first. Subjects in the surgical arm with a focus of contrast-enhancing tumor that is amenable to SRS will be assigned to surgical sub-arm #1 of Cohort B (N=8). These subjects will receive neoadjuvant INCMGA00012 + INCAGN01876 + SRS. All other subjects enrolled on Cohort B (N=8) are treated with neoadjvuant INCMGA00012 + INCAGN01876 (without SRS).

  16. Reproductive Status

    1. Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 7 days prior to the start of study drug.
    2. Women must agree to not breastfeed during the study or for 180 days after the last dose of study treatment

    4. Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception (as defined below) starting with the first dose of study drug through 180 days after the last dose of study
    5. Azoospermic males and WOCBP who are continuously not heterosexually active are exempt from contraceptive requirements. However, these WOCBP must still undergo pregnancy testing as described in this section.

    At a minimum, participants of childbearing potential who are sexually active and their partners must agree to the use of a highly effective form of contraception (as defined below) throughout their participation beginning with the time of consent, during the study treatment, and for 180 days after last dose of study treatment(s).

    HIGHLY EFFECTIVE METHODS OF CONTRACEPTION:

    • Hormonal methods of contraception including combined oral contraceptive pills, vaginal ring, injectables, implants and intrauterine devices (IUDs) by WOCBP subject or male subject's WOCBP partner. Female partners of male subjects participating in the study may use hormone-based contraceptives as one of the acceptable methods of contraception since they will not be receiving study drug
    • Nonhormonal IUDs
    • Bilateral Tubal ligation
    • Vasectomy
    • Sexual Abstinence

      • It is not necessary to use any other method of contraception when complete abstinence is elected.

      • Acceptable alternate methods of highly effective contraception must be discussed in the event that the WOCBP participants chooses to forego complete abstinence.
  17. Participant must, in the opinion of the Investigator, be able to comply with study procedures
  18. Patients must be able to understand the study procedures and agree to participate in the study by providing written informed consent (or have legally authorized representative sign on patient's behalf if patient physically unable to sign consent due to neurologic deficit)

Exclusion Criteria

Any of the following would exclude the subject from participation in the study:

  2. Diffuse leptomeningeal disease
  3. Prior bevacizumab or other vascular endothelial growth factor (VEGF/VEGFR) inhibitors (exception: prior bevacizumab is allowed if it was administered for the treatment of radiation necrosis rather than progressive tumor and was stopped at least 4 weeks prior to MRI showing demonstrating tumor progression).
  4. Patients with clinically significant mass effect or midline shift (e.g., 1-2 cm of midline shift)

    EXCEPTIONS: Subjects with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, adrenal insufficiency requiring only replacement dose corticosteroids, skin disorders (such as vitiligo, psoriasis, pemphigus, or alopecia) controlled with topical medications, or conditions not expected to recur in the absence of an external trigger are permitted to enroll. Patients with asthma that is not actively flaring are allowed. Patients with history of Grave's disease that is previously treated with thyroidectomy or radioiodine are allowed. Patients with celiac disease whose symptoms are controlled with a gluten-free diet are allowed. Patients with rheumatoid arthritis and other arthropathies such as ankylosing spondylitis, Sjogren's syndrome, Raynaud syndrome, and patients with positive serologies, such as antinuclear antibodies (ANA) or anti-thyroid antibodies, should be evaluated for the presence of target organ involvement and potential need for systemic treatment but should otherwise be eligible.
