This phase 1b trial studies the side effects and best dose of telaglenastat in combination with radiation therapy and temozolomide in treating patients with IDH-mutated diffuse or anaplastic astrocytoma. Telaglenastat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving telaglenastat with radiation therapy and temozolomide may work better than surgery, radiation therapy, and temozolomide in treating patients with IDH-mutated diffuse astrocytoma or anaplastic astrocytoma.

PRIMARY OBJECTIVE:

I. Determine the maximum tolerated dose (MTD) and/or the recommended phase 2 dose (RP2D) of telaglenastat (CB-839) hydrochloride (HCl) when combined with radiation therapy (RT) and temozolomide (TMZ) in patients with newly diagnosed IDH-mutated diffuse astrocytoma (DA) and anaplastic astrocytoma (AA).

Telaglenastat With Radiation Therapy and Temozolomide in Treating Patients With IDH-Mutated Diffuse Astrocytoma or Anaplastic Astrocytoma

A Phase 1b Trial of Telaglenastat (CB-839) HCI in Combination With Radiation Therapy and Temozolomide in Patients With IDH-Mutated Diffuse Astrocytoma and Anaplastic Astrocytoma

MTD is defined as the dose level below the lowest dose that induces dose limiting toxicity (DLT) in at least 2 patients (out of 6). A total of 6 patients must be treated at the MTD. It is possible that the MTD will be unknown after this study (e.g., if the highest tested dose has fewer than 2 patients with DLT, out of 6). In this case, the highest dose is defined as the RP2D. A 3 + 3 cohort expansion design to determine toxicity-based dose escalation of telaglenastat (CB-839) hydrochloride (HCl) and external beam fractionated radiation therapy (RT) with concurrent temozolomide (TMZ) among patients with IDH-mutated diffuse astrocytoma (DA) or anaplastic astrocytoma (AA).

ORR is defined as the rate of either complete response (CR), partial response (PR), or minor response (MR) by RANO criteria for low-grade gliomas at 6 months after initiation of RT/TMZ/telaglenastat (CB-839) HCl therapy. The ORR will be estimated using properties of the binomial distribution. 95% exact confidence intervals will also be calculated.

CBR is defined as the rate of either CR, PR, MR, or stable disease (SD) by RANO criteria for low-grade gliomas at 6 months after initiation of RT/TMZ/telaglenastat (CB-839) HCl therapy. The CBR will be estimated using properties of the binomial distribution. 95% exact confidence intervals will also be calculated.

The safety and tolerability of RT/TMZ/telaglenastat (CB-839) HCl in patients is based on physician reported adverse event (AE) data.

PFS2 rate will be estimated using properties of the binomial distribution. 95% exact confidence intervals will also be calculated.

OS2 rate will be estimated using properties of the binomial distribution. 95% exact confidence intervals will also be calculated.

The PK of telaglenastat (CB-839) HCl will also be summarized using descriptive statistics and will be compared to historical data. Measurement of plasma concentrations of telaglenastat (CB-839) HCl and its metabolites (if authentic standards are available) will be performed using validated liquid chromatography-tandem mass spectrometry (LC/MS/MS) assays. The plasma concentration-time data will be analyzed by standard noncompartmental analysis using the program Phoenix WinNonlin 6.4 to determine apparent total clearance of the drug from plasma after oral administration (Cl/F), area under the plasma concentration-time curve from time zero to time t (AUCt), area under the plasma concentration-time curve from time zero to infinity, Cmax, time to reach maximum plasma concentration following drug administration (Tmax), t1/2, and accumulation.

MDASI-BT instrument is used to measure self-reported symptom severity and interference with daily activities. The study will use descriptive statistics to describe how patients rate symptom severity and interference with function at each time point. Compliance rates will be calculated as the number of received valid forms over the number of expected forms. Differences between groups in compliance will be tested by use of Fisher's exact test at every time point.

For each test in the battery, a standard error of measurement will be used to derive the Reliable Change Index (RCI) which will be used to represent the 90% confidence interval for the difference in raw scores from baseline to follow-up assessment will be coded as 1 (deterioration), 2 (no change), and 3 (improved) according to the RCI. Percentage of patients in each dose cohort who show meaningful losses or gains in the various tests or test domains over the course of the study will be provided by frequency tables. Dose cohort differences will be compared using chi-squared analysis. Time-to-progressions will be estimated by Kaplan-Meier method and analyzed by Cox regression model adjusting all stratification factors.

Plasma oncometabolites (asparagine, aspartate, glutamine, glutamate, and 2-HG) will be compared using changes in values after treatment with the patient's individual baseline values using either the paired t-test or the Mann-Whitney nonparametric U-test as needed. A significant change is defined as a 10% change from baseline.

Tumor oncometabolites (2-HG, glutamine, and glutamate, as measured by MRS) will be compared using changes in values after treatment with the patient's individual baseline values using either the paired t-test or the Mann-Whitney nonparametric U-test as needed. A significant change is defined as a 10% change from baseline.

Magnetic Resonance Imaging

Pharmacodynamic Study

Funda Meric-Bernstam

This phase II trial studies how well glutaminase inhibitor telaglenastat hydrochloride (CB-839 HCl) works in treating patients with specific genetic mutations and solid tumors or malignant peripheral nerve sheath tumors that have spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). Glutaminase converts an amino acid (building block of proteins) called glutamine to glutamate, which can support several cellular pathways. Telaglenastat hydrochloride works by blocking glutamine activity needed for the growth of cells. When this activity is blocked, the growth of cancer cells may stop and the cancer cells may then die. Cancer is caused by changes (mutations) to genes that control the way cells function and uncontrolled cell growth may result in tumor formation. Specific genetic mutations studied in this clinical trial are NF1 mutation for malignant peripheral nerve sheath tumors, and NF1, KEAP1/NRF2, or STK11/LKB1 mutation for other solid tumors. Telaglenastat hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PRIMARY OBJECTIVE:

I. To assess the best overall response rate (BORR) achieved by 6 months of telaglenastat (CB-839) hydrochloride (HCl) treatment in specific pathway aberrant tumors (MPNST, NF1, KEAP1/NRF2 \& STK11/ LKB1).

SECONDARY OBJECTIVES:

I. To determine the safety, progression-free survival (PFS), time to progression (TTP) and overall survival (OS).

II. To determine the overall response rate (ORR) (highest objective response achieved between start of therapy and progression), time to response (TTR) and clinical benefit rate (CBR) of telaglenastat (CB-839)HCl.

III. To assess pharmacodynamic changes and adaptive responses and correlate with response to treatment as well as disease progression (correlative objective).

EXPLORATORY OBJECTIVES:

I. Correlate fludeoxyglucose F-18 (18-F FDG) positron emission tomography (PET)/computed tomography (CT) pre-therapy and 8-weeks post-therapy response to telaglenastat (CB-839) HCl therapy.

II. Evaluate changes in level of circulating tumor deoxyribonucleic acid (DNA) at baseline, one month on-treatment and time of progression (Molecular Characterization Laboratory \[MoCHA Labs\]) to treatment response.

III. Quantify the peripheral blood concentrations of the metabolites: aspartate, glutamate, glutamine and arginine (@Mayo clinic Oncometabolomics core) and correlate with response.

IV. Evaluate the pharmacodynamic (PD) effect of telaglenastat (CB-839) HCl on systemic levels of the tricarboxylic acid (TCA) cycle metabolites in peripheral blood (baseline and one month) as part of the protocol.

V. Evaluate tumor by reverse phase protein array (@core facility at MD Anderson) and ribonucleic acid (RNA) sequencing (seq) to evaluate changes from pre-treatment, during treatment and post treatment specimens.

VI. Perform patient-derived tumor xenograft (PDX) modelling-co-clinical trials (@Dr. Funda Meric-Bernstam's lab MD Anderson) to understand response/resistance mechanisms and also evaluate combination therapies for future development.

OUTLINE:

The number and severity of all AEs (overall and by dose-level) will be tabulated and summarized in this patient population. These data will be summarized with and without regard to the relationship to the treatment (i.e., ignoring the relationship data and after sub-setting the data to only events that are at least possibly related to study drug).

The ORR will be defined as the percentage of patients that achieve at least a partial response (as their best response). Properties of the binomial distribution will be used in order to construct an exact 95% confidence interval around this proportion.
