Basic Information

• Study Start Date: 2020-07-08

Brief Summary

The purpose of this study is to evaluate any preliminary evidence of anticancer activity of pembrolizumab combined with either pemetrexed or abemaciclib when used following surgery and before standard therapy with radiation and temozolomide in patients with newly diagnosed high grade glioma.

Additional aims of the study are to:

• Find out the side effects (good and bad) of pembrolizumab combined with pemetrexed or abemaciclib;
• • Evaluate tumor characteristics by collecting brain tumor tissue samples.
• Measure the amount of pembrolizumab, pemetrexed, and/or abemaciclib that gets in the body by collecting blood and cerebrospinal fluid.
• Look at biomarkers (biochemical features that can be used to measure the progress of disease or the effects of a drug) in blood and cerebrospinal fluid if available.

Detailed Description

This is a prospective, open-label, multi-arm exploratory study of pembrolizumab in combination with pemetrexed or abemaciclib for the treatment of adult patients with newly diagnosed high grade glioma. Patients having a clinically planned surgical procedure (biopsy or cytoreduction) for a suspected diagnosis of high grade glioma will be approached for participation in this study. Tumor tissue obtained from surgery will be used for histological diagnosis and clinical molecular profiling, and excess tumor tissue may be collected for potential correlative studies. A small sample of blood and cerebrospinal fluid (CSF) for research will also be collected.

Once a diagnosis of high grade glioma is confirmed, the patient will be allocated to either Treatment Arm 1 (pembrolizumab + pemetrexed), or Treatment Arm 2 (pembrolizumab + abemaciclib). Treatment will be started approximately 7-42 days following surgery once the patient has recovered from surgery. Routine clinical evaluations will be performed prior to treatment initiation and throughout treatment as clinically indicated. Radiographic brain imaging will be performed approximately 21-42 after treatment initiation and then routinely for medical management. Tumor response will be assessed according to immunotherapy Response Assessment in Neuro-Oncology (iRANO) Working Group criteria.

Treatment may continue until the patient experiences unacceptable toxicity or clear disease progression. The determination of whether to stop treatment due to disease progression will be based on the investigator's evaluation of the patient's clinical and radiographic condition, taking into consideration the interpretation of localized inflammatory responses that can mimic radiographic features of tumor progress. Patients discontinuing treatment will be directed by their treating physician to either receive a different treatment regimen (e.g., standard radiation therapy with or without chemotherapy) or undergo a clinically-indicated cytoreductive surgery. If another treatment is started, clinical evaluations and response assessments will continue as clinically-indicated and blood and CSF will be collected after the first month, then every three months.

Eligibility Criteria

Inclusion Criteria

1. Participant or their legal representative has the ability to provide informed consent.

2. Participant has the willingness to comply with all study procedures and availability for the duration of the study.

3. Participant is being evaluated for a potential, or known, diagnosis of high grade glioma.

Note:Participant must have a diagnosis of high grade (WHO Grade III or IV) glioma following brain surgery to proceed with study treatment.

4. Participant is a candidate for brain surgery.

5. Participant is male or female, ≥ 18 years of age.

6. Participant has a Karnofsky Performance Status ≥ 60%.

7. Participant has adequate organ function:

1. ANC at least 1.5 x 10^9/L or greater.

2. Platelets at least 100 x 10^9/L or greater.

3. Hemoglobin at least 8 g/dL or greater.

4. Total bilirubin 1.5 x upper limit of normal (ULN) or lower.

5. ALT and AST 3 x ULN or lower.

6. Serum creatinine 1.5 x ULN or lower.

1. Participant has the ability to interrupt nonsteroidal anti-inflammatory (NSAIDS) 2 days before (5 days for long-acting NSAIDs), the day of, and 2 days following administration of Pemetrexed.

2. Participant has the ability to take folic acid, Vitamin B12, and dexamethasone according to protocol.

3. Creatinine clearance ≥ 45 mL/min (calculated using standard Cockcroft and Gault formula).

1. Participant is able to swallow oral medications.

Exclusion Criteria

1. Participant has received prior anti-cancer treatment for high-grade glioma.

2. Participant has a diagnosis of immunodeficiency or active autoimmune disease.

3. Participant is receiving chronic systemic steroid therapy in dosing exceeding 8 mg daily of dexamethasone equivalent or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug. This is assessed after surgery, prior to starting drug treatment.

4. Participant has received a live vaccine within 28 days prior to the first dose of study agent. Examples of live vaccines include, but are not limited to measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), typhoid vaccine, and intranasal influenza vaccines (e.g., FluMist®).

5. Participant has a severe or uncontrolled medical disorder that would, in the investigator's opinion, impair ability to receive study intervention, including, but not limited to:

1. Uncontrolled diabetes;

2. Renal disease that requires dialysis;

3. Pulmonary disorder requiring supplemental oxygen to keep saturation >95% and the situation is not expected to resolve within 2 weeks;

4. Severe dyspnea at rest or requiring oxygen therapy;

5. Interstitial lung disease;

6. History of major surgical resection involving the stomach or small bowel;

7. Preexisting Crohn's disease;

8. Ulcerative colitis;

9. Uncontrolled vasculitis and/or disease with known vasculitis;

10. Preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea;

For patients who develop or have baseline clinically significant pleural or peritoneal effusions (on the basis of symptoms or clinical examination) before or during initiation of pemetrexed therapy, consideration should be given to draining the effusion prior to dosing. However, if, in the investigator's opinion, the effusion represents progression of disease, the patient should be discontinued from study therapy.
