Study Details
Study Description
Brief Summary
This research study is studying an immunotherapy as a possible treatment for Glioblastoma.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Phase 1 |
Detailed Description
PD-1 works to help tumor cells continue to grow and multiply. Pembrolizumab (MK-3475) is a humanized monoclonal antibody. Humanized monoclonal is an antibody that is designed to block the action of the receptor, PD-1.
The FDA (the U.S. Food and Drug Administration) has not approved Pembrolizumab for Glioblastoma but it has been approved for other uses.

Outcome Measures
Primary Outcome Measures
- Tumor Infiltrating T Lymphocyte (TIL) Density [2 years]
To measure changes in tumor infiltrating T lymphocyte (TIL) density. It will be assessed using pooled Group A and Group B patients and compared to appropriate historical controls.
- Incidence of Treatment-Emergent Adverse Events [2 years]
Safety will be assessed by quantifying the toxicities and grades experienced by subjects who have received Pembrolizumab, including serious adverse events (SAEs) and events of clinical interest (ECIs). The following will also be measured as part of safety: laboratory safety assessments, KPS status, vital signs and physical examinations.
Secondary Outcome Measures
- Progression Free Survival [180 Days]
To determine the efficacy of pembrolizumab in patients with surgically accessible recurrent/progressive glioblastoma (GBM) participants as measured by 6-month progression-free survival (PFS6) using RANO criteria.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Have histologically confirmed World Health Organization Grade IV malignant glioma (glioblastoma or gliosarcoma). Participants will be eligible if the original histology was low-grade glioma and a subsequent histological diagnosis of glioblastoma or variants is made.
-
Be willing and able to provide written informed consent/assent for the trial.
-
Be 18 years of age on day of signing informed consent.
-
Have a Karnofsky performance status (KPS) ≥ 70 (Appendix A).

-
From registration, the following time periods must have elapsed: 5 half-lives from any investigational agent, 4 weeks from cytotoxic therapy (except 23 days for temozolomide and 6 weeks from nitrosoureas), 6 weeks from antibodies, or 4 weeks (or 5 half-lives, whichever is shorter) from other anti-tumor therapies (including vaccines). No wash-out period required from TTF.
-

-
1 formalin-fixed paraffin-embedded (FFPE) tumor tissue block (preferred) OR
-
10 FFPE unstained slides (5 μm thick)
-
Patients must be undergoing surgery that is clinically indicated as determined by their care providers. Patients must be eligible for surgical resection with the expectation that the surgeon is able to resect at least 400mg of tumor with low risk of inducing neurological injury.
-
Female subject of childbearing potential must have a negative urine or serum pregnancy within 72 hours prior to registration. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum FSH levels > 40 mIU/mL and estradiol < 20 pg/mL or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.
-
Women of child-bearing potential (WOCBP), defined as all women physiologically capable of becoming pregnant, must agree to use highly effective contraception during study treatment and for 120 days after study discontinuation. Highly effective contraception is defined as either:
-
True Abstinence: When this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
-
Sterilization: Surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment (as described in item 3.1.16 above).
-
Male Partner Sterilization (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate). For female subjects on the study, the vasectomised male partner must be the sole partner for that participant.
-
Use of a combination of any two of the following:
-
Placement of an intrauterine device (IUD) or intrauterine system (IUS)
