Summary

The purpose of this study is to test the side effects and efficacy of using Laser Interstitial Thermotherapy (LITT) combined with Pembrolizumab. LITT is a minimally invasive surgical technique that uses a laser to heat brain tumors.

Pembrolizumab is an investigational (experimental) drug that works by helping participants' immune system work correctly to detect and fight cancer cells. Pembrolizumab is experimental because it is not approved by the Food and Drug Administration (FDA), for this use, though it is approved to treat other cancers.

Description

Primary Objectives:

  1. Phase I: To determine the optimal timing for combining LITT and pembrolizumab in patients with rGBM:

• To determine the feasibility, safety, tolerability and side effect profiles for combining LITT and pembrolizumab at various time points pre-LITT vs. post-LITT (Phase I).

2. Phase II: To estimate the response to pembrolizumab combined with LITT in patients with rGBM;

• To estimate the response rate after treatment with LITT combined with pembrolizumab in patients with rGBM (Phase II).

3. To collect and record the side effect profiles for combining LITT and pembrolizumab (Phase I and Phase II).

Secondary Objectives:

  1. To determine the effect of pembrolizumab on systemic immune microenvironment in patients with rGBM.
  2. To determine the effect of pembrolizumab on the intra-tumoral immunosuppressive microenvironment within rGBM.
  3. Secondary for Phase II, to estimate progression free survival (PFS) and overall survival (OS) after treatment with LITT combined with pembrolizumab in patients with rGBM (Phase II).
  4. Measure radiological response using both conventional RANO criterion, a modified RANO (RANOi) designed specifically for immunotherapy response assessment, as well as MRI fingerprinting (MRF), recently demonstrated by the PI and collaborators to accurately and precisely distinguish recurrent GBM from radiation injury.
  5. Correlate clinical and radiological response to known biomarkers of GBM such as Isocitrate Dehydrogenase 1 (IDH-1) mutations, Isocitrate Dehydrogenase 2 (IDH-2) mutations, Methyl-Guanine Methyl Transferase (MGMT) promoter methylation, Phosphatase and tensin homologue (PTEN) loss and KI-67.

Study Design:

The Phase I component will involve up to two of a possible 3 cohorts of 3-4 patients each for a total of 6-8 evaluable patients. Each patient will undergo a stereotactic biopsy. If GBM or Gliosarcoma is confirmed by frozen section, patients will undergo LITT then treatment with 200 mg pembrolizumab IV. Cohort I will receive pembrolizumab on post operative day 14 and every 3 weeks thereafter. In the event that one patient suffers non-hematologic toxicity of grade 3 or more, or if hematologic toxicity is grade 4 or higher, the investigators will delay the 2nd dose of pembrolizumab by 3 weeks and a 4th patient will be accrued. If there are two patients in the initial cohort with non-hematologic toxicities grade 3, or if hematological toxicity in two patients is grade 4 or higher, the second cohort will delay initiation of pembrolizumab until post operative day 35 after LITT. Conversely, if there are no non-hematologic adverse events (AEs) of grade 3 or higher, the investigators will proceed to cohort IB using the same dose of pembrolizumab given 7 days prior to surgery, then every 3 weeks. Similarly, feasibility and safety will be addressed as above in deciding whether or not to proceed to the next cohort.

The Phase II component of the study will consist of additional patients receiving pembrolizumab at the earliest tolerated time post LITT:

  • 14 days post-op
  • -7 days pre-op;
  • 35 days post-opto achieve a total of 23 evaluable patients at the earliest tolerated dose.

Acquired immune deficiency syndrome (AIDS) based upon current Center for Disease Control and Prevention (CDC) definition; note, however, that HIV testing is not required for entry into this protocol. The need to exclude patients with AIDS from this protocol is necessary because the treatments involved in this protocol may be significantly immunosuppressive and worsen the patient's HIV symptoms
Active connective tissue disorders, such as lupus or scleroderma, which in the opinion of the treating physician may put the patient at high risk for immunologic toxicity
History of (non-infectious) pneumonitis that required steroids, evidence of interstitial lung disease or active, non-infectious pneumonitis
Patients with active autoimmune disease or history of autoimmune disease that might recur, which may affect vital organ function or require immune suppressive treatment including systemic corticosteroids, should be excluded. These include but are not limited to patients with a history of immune related neurologic disease, multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain-Barre syndrome or Chronic Inflammatory Demyelinating Polyneuropathy, myasthenia gravis; systemic autoimmune disease such as Systemic Lupus Erythematosus, connective tissue diseases, scleroderma, inflammatory bowel disease (IBD), Crohn's, ulcerative colitis, hepatitis; and patients with a history of toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome, or phospholipid syndrome should be excluded because of the risk of recurrence or exacerbation of disease

Of note, patients with vitiligo, endocrine deficiencies including thyroiditis managed with replacement hormones including physiologic corticosteroids are eligible. Patients with rheumatoid arthritis and other arthropathies, Sjögren's syndrome and psoriasis controlled with topical medication and patients with positive serology, such as antinuclear antibodies (ANA), anti-thyroid antibodies should be evaluated for the presence of target organ involvement and potential need for systemic treatment but should otherwise be eligible
Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer
Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis.

This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability
Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment

Patient must have < 1.0 cm midline shift pre-operative
History of severe hypersensitivity reaction to any monoclonal antibody including pembrolizumab
Has received a live vaccine within 30 days of planned start of study therapy. --- Note: Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however Intranasal influenza vaccines (e.g., Flu-Mist®) are live attenuated vaccines, and are not allowed
Patients who cannot safely undergo MRI due to non-MRI compatible pacemaker, or other reason
Patients who have tumors for which the Gd-enhancing mass appears to be covered ≤ 90% using 2 catheters and assuming a 3.0 cm diameter based on pre-operative planning are unlikely to have adequate LITT and thus ineligible for the study
