Lung Cancer Clinical Trial

Telaglenastat Hydrochloride and Osimertinib in Treating Patients With EGFR-Mutated Stage IV Non-small Cell Lung Cancer

Summary

This phase Ib trial studies the side effects and best dose of telaglenastat hydrochloride when given together with osimertinib in treating patients with stage IV non-small cell lung cancer and a mutation in the EGFR gene. Telaglenastat hydrochloride and osimertinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PRIMARY OBJECTIVE:

I.To assess the safety and tolerability of osimertinib (AZD9291) and telaglenastat (CB-839) hydrochloride (HCl) and determine the recommended phase II dose (RP2D) in patients with metastatic, EGFR activating mutation-positive non-small cell lung cancer (NSCLC).

SECONDARY OBJECTIVES:

I. To determine toxicity profile of the combination of osimertinib (AZD9291) and telaglenastat (CB-839) HCl in patients with metastatic EGFR activating mutation positive NSCLC.

II. To assess the pharmacokinetics (PK) of telaglenastat (CB-839) HCl and osimertinib (AZD9291) in patients with metastatic EGFR activating mutation positive NSCLC.

EXPLORATORY/CORRELATIVE OBJECTIVES:

I. To determine the progression free survival (PFS) of osimertinib (AZD9291) and telaglenastat (CB-839) HCl in patients with EGFR mutation positive NSCLC who have developed progressive disease (PD) on front-line EGFR inhibitor therapy.

II. To determine the overall survival (OS) of osimertinib (AZD9291) and telaglenastat (CB-839) HCl in patients with EGFR mutation positive NSCLC who have developed PD on front-line EGFR inhibitor therapy.

III. To assess cell-free deoxyribonucleic acid (DNA) (cfDNA) and measure changes with response to treatment as well as disease progression (EGFR sensitizing mutations, T790M resistance mutation, recognized bypass mechanisms).

IV. To assess circulating levels of glutamine, glutamate, aspartate and asparagine, and measure changes with response to treatment as well as disease progression.

V. To assess 18F-fluorodeoxyglucose (18F-FDG)-positron emission tomography (PET) parameters at baseline and after treatment to evaluate changes with response to treatment as well as emergence of disease resistance or progression. (Expansion cohort, select patients only)

VI. To perform molecular profiling assays on malignant and normal tissues, including, but not limited to, whole exome sequencing (WES) and ribonucleic acid (RNA) sequencing (RNAseq), in order to:

VIa. To identify potential predictive and prognostic biomarkers beyond any genomic alteration by which treatment may be assigned.

VIb. To identify resistance mechanisms using genomic DNA- and RNA-based assessment platforms.

OUTLINE: This is a phase I, dose-escalation study of telaglenastat hydrochloride followed by a dose-expansion study.

Patients receive telaglenastat hydrochloride orally (PO) twice daily (BID) and osimertinib PO once daily (QD) (starting cycle 1 day 16 of phase I). Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days.

Creatinine within 1.5 x ULN OR
Glomerular filtration rate (GFR) >= 50 mL/min/1.73 m^2 (measured or calculated by Cockcroft and Gault equation) - confirmation of creatinine clearance is only required for patients with creatinine levels above institutional upper limit of normal

If evidence of chronic hepatitis B virus (HBV) infection, HBV viral load must be undetectable on suppressive therapy if indicated. Participants with a resolved or chronic infection HBV are eligible if they are:

Negative for hepatitis B surface antigen (HBsAg) and positive for hepatitis B core antibody (anti-HBc immunoglobulin G [IgG]), or;
Positive for HBsAg, negative for hepatitis B e-antigen (HBeAg) but for > 6 months have had transaminases levels below ULN and HBV DNA levels below 2000 IU/mL (i.e., are in an inactive carrier state)
If history of hepatitis C virus (HCV) infection, must be treated and have an undetectable HCV viral load
Patients with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS) - directed therapy shows no evidence of progression
Patients with new or progressive brain metastases (active brain metastases) or leptomeningeal disease are eligible if the treating physician determines that immediate CNS specific treatment is not required and is unlikely to be required during the first cycle of therapy. Patients on corticosteroids for the treatment of brain metastases will be permitted as long as the dose is =< 10 mg of prednisone-equivalent and has not been increased within 2 weeks of screening
Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial

EXPANSION COHORT: Patients must have had progressive disease on prior first line EGFR inhibitor therapy with osimertinib

Exclusion Criteria:

Patients who have not recovered from AEs due to prior systemic anti-cancer therapy (i.e., have residual toxicities > grade 1), with the exception of alopecia. Note: Subjects with irreversible toxicity that in the opinion of the treating physician is not reasonably expected to be exacerbated by the investigational treatment may be included (e.g., hearing loss, hormone deficiency requiring replacement therapy)
Previous enrollment in the present study
Past medical history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonitis requiring steroid treatment, or any evidence of clinically active interstitial lung disease
Patients who are receiving any other investigational agent within five half-lives of the compound or 3 months, whichever is greater. Patients who have received prior immunotherapy may be included only if time from last immunotherapy is at least 3 months (i.e. 90 days)
Spinal cord compression, symptomatic and unstable brain metastases except for those patients who have completed definitive therapy, and have had a stable neurological status for at least 2 weeks after completion of definitive therapy.

All patients must try to avoid concomitant use of any medications, herbal supplements and/or ingestion of foods with known inducer effects on CYP3A4
Pregnant women are excluded from this study because telaglenastat (CB-839) HCl is a glutaminase inhibitor with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for AEs in nursing infants secondary to treatment of the mother with telaglenastat (CB-839) HCl and osimertinib (AZD9291), breastfeeding should be discontinued if the mother is treated with telaglenastat (CB-839) HCl and osimertinib (AZD9291). Breastfeeding patients will be excluded. These potential risks may also apply to other agents used in this study
Patients with a significant history of cardiovascular disease (e.g., myocardial infarction [MI], thrombotic or thromboembolic event in the last 6 months)

Any of the following cardiac criteria:

Mean resting corrected QT interval (QTc using Fridericia's formula [QTcF]) > 470 msec (Fridericia's Criteria for Corrected QT interval [QTc] Calculation: Fridericia's formula QTcF = (QT/RR 0.33). RR is the time from the interval of 1 QRS complex to the next measured in seconds and is commonly calculated as (60/HR)
Any clinically important abnormalities in rhythm, conduction or morphology of resting electrocardiogram (ECG) (e.g., complete left bundle branch block, third degree heart block, second degree heart block)
Any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, electrolyte abnormalities (including: Serum/plasma potassium < lower limit of normal (LLN); serum/plasma magnesium < LLN; serum/plasma calcium < LLN , congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years of age in first degree relatives, or any concomitant medication known to prolong the QT interval and cause Torsades de Pointes

Patients with active malignancies other than NSCLC or patients with prior curatively treated malignancy at high risk of relapse during the study period with the exception of localized squamous or basal cell skin cancers, ductal carcinoma in-situ (DCIS), or indolent cancer currently on observation (i.e. chronic lymphocytic leukemia [CLL] or low-risk prostate cancer)
Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension and active bleeding diatheses, which in the investigator's opinion makes it undesirable for the patient to participate in the trial or which would jeopardize compliance with the protocol, or active infection with human immunodeficiency virus (HIV). Screening for chronic conditions is not required
Patients with symptomatic CNS metastases who are neurologically unstable
Patients who are at risk for impaired absorption of oral medication including, but not limited to, refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product or previous significant bowel resection that would preclude adequate absorption of telaglenastat (CB-839) HCl and osimertinib (AZD9291)
Judgment by the investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions and requirements
Involvement in the planning and/or conduct of the study (applies to both investigator staff and/or staff at the study site)
