Melanoma Clinical Trial

Radiation Therapy With Temozolomide and Pembrolizumab in Treating Patients With Newly Diagnosed Glioblastoma

Summary

The purpose of phase I trial is to determine the safest, most effective dose of MK-3475 (pembrolizumab), when used with radiotherapy and temozolomide for treating newly diagnosed patients with glioblastoma (GBM). Temozolomide binds to the deoxyribonucleic acid (DNA), changes it, and triggers the death of tumor cells. MK-3475 is an investigational drug, it is not currently approved by the Federal Drug Administration (FDA) for use in treating GBM but it is approved for treating melanoma. MK-3475 works by targets the local tumor immune-protection in solid tumors. It is hoped the addition of MK-3475 to the usual treatment for GBM will improve the current treatment.

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of radiation therapy (RT) + temozolomide (TMZ) + MK-3475 (pembrolizumab) followed by MK-3475 + TMZ x 6 cycles (1 cycle is 9 weeks), MK-3475 can continue for an additional 12 months.

SECONDARY OBJECTIVES:

Safety of MK-3475 in GBM.

TERTIARY OBJECTIVES:

I. To determine if there is a correlation of programmed cell death 1 (PD1) or programmed cell death 1 ligand 1 (PDL1) expression and T-cell infiltrate in pathology from first and, if applicable, second surgical specimens with outcome.

II. Assess changes in peripheral T-cell activation and tryptophan metabolites. III. Correlate o-6-methylguanine-deoxyribonucleic acid (DNA) methyltransferase (MGMT) status with outcome.

OUTLINE: This is a phase I, dose-escalation study of pembrolizumab, followed by a phase II study.

RT PORTION: Patients undergo focal RT over 42 days, and receive concurrent temozolomide orally (PO) once daily (QD) on days 1-42 and pembrolizumab IV over 30 minutes on days 1, 22, and 43.

POST-RT: After completion of RT, patients receive temozolomide PO QD on days 1-5 and 29-34 of course 1 and days 1-5 and 29-33 of subsequent courses, and pembrolizumab IV over 30 minutes on days 1, 22, and 43. Treatment repeats every 9 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity. After 6 courses, patients deriving benefit may continue to receive pembrolizumab for an additional 12 months.

After completion of study treatment, patients are followed up every 2-4 months.

Eligibility Criteria

Inclusion Criteria:

Histologically confirmed newly diagnosed glioblastoma; patients with an initial diagnosis of a lower-grade glioma are eligible if a subsequent biopsy was determined to be glioblastoma and they received no prior treatment
No prior treatment with radiation or chemotherapy for their GBM
No prior treatment with carmustine wafers

Patients who have undergone recent surgery:

Must be a minimum of 14 days from surgery
Craniotomy or intracranial biopsy site must be adequately healed and free of drainage or cellulitis, and the underlying cranioplasty must appear intact at the time of registration
Magnetic resonance imaging (MRI) within 72 hours of surgery OR 4 weeks from surgery
Karnofsky performance status >= 70%
Stable or decreasing dose of corticosteroids within 5 days prior to treatment
Female subject of childbearing potential should have a negative urine or serum pregnancy within 7 days prior to receiving the first dose of study medication; if the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
Patients need not have measurable or evaluable disease
Absolute neutrophil count (ANC) > 1.5 x 10^9/L
Platelet count > 100 x 10^9/L; or
Hemoglobin (Hb) > 9.0 g/dL within 7 days prior to enrollment; note: the use of transfusion or other intervention to achieve Hb >= 9 g/dL is acceptable
Total bilirubin =< 1.5 x upper limit of normal (ULN) (except in patients diagnosed with Gilbert's disease)
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]), alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x ULN
Alkaline phosphatase (ALP) =< 2.5 x ULN
Serum creatinine < 1.5 x ULN
International normalized ratio (INR), prothrombin time (PT), or activated partial thromboplastin time (APTT) as follows: in the absence of therapeutic intent to anticoagulate the patient: INR < 1.5 or PT < 1.5 x ULN or aPTT < 1.5 x ULN; in the presence of therapeutic intent to anticoagulate the patient: INR or PT and aPTT within therapeutic limits (according to the medical standard in the institution) and the patient has been on a stable dose of anticoagulants for at least 2 weeks before registration

Females of child-bearing potential (FOCBP) and males must agree to use two adequate contraception methods (give examples, e.g. hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 120 days following completion of therapy; should a female patient become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately

NOTE: A FOCBP is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:

Has not undergone a hysterectomy or bilateral oophorectomy
Has had menses at any time in the preceding 12 consecutive months (and therefore has not been naturally postmenopausal for > 12 months)
Patients must have the ability to understand and the willingness to sign a written informed consent prior to registration on study

Exclusion Criteria:

Any prior treatment for the patients GBM
Has a known diagnosis of immunodeficiency (human immunodeficiency virus [HIV] 1/2 antibodies) or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment excluding steroids; attempts should be made to have patient on lowest possible dose of steroids

Hypertension (defined as 160/95) that is not controlled on medication
Ongoing or active infection requiring systemic treatment
Symptomatic congestive heart failure
