What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine the optimal dose and understand the side effects of combining telaglenastat hydrochloride with osimertinib, a targeted therapy drug, for treating stage IV non-small cell lung cancer, particularly in patients with a specific EGFR gene mutation. These drugs block certain enzymes that fuel tumor growth. This trial may suit those with stage IV non-small cell lung cancer who have previously taken EGFR inhibitor therapy and experienced disease progression. Participants should be able to swallow pills and have a life expectancy of more than three months. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this combination therapy.

Will I have to stop taking my current medications?

The trial does not specify if you must stop taking your current medications, but you should avoid medications or supplements that strongly affect CYP3A4 enzymes. It's best to discuss your current medications with the trial team to ensure they don't interfere with the study.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that telaglenastat hydrochloride, when combined with other treatments, is generally well tolerated by patients. A previous study found no unexpected safety issues, although effectiveness varied among different groups. Osimertinib, already approved for treating advanced non-small cell lung cancer (NSCLC) with specific mutations, demonstrated a strong response in similar patients and was considered safe without any surprises.

These drugs work together to stop cancer cells from growing by blocking certain enzymes the cells need. While both treatments have been studied individually, this trial explores their combined effectiveness and aims to determine the best dose. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about telaglenastat combined with osimertinib for non-small cell lung cancer because it offers a unique approach to treatment. Unlike standard therapies that often target specific mutations, telaglenastat inhibits glutaminase, an enzyme that cancer cells rely on for growth. This combination aims to starve the cancer cells of the nutrients they need to survive. Meanwhile, osimertinib is an established treatment targeting EGFR mutations, making this combo a promising strategy to tackle cancer from multiple angles. This dual-action approach could potentially improve outcomes for patients with this type of lung cancer.

What evidence suggests that telaglenastat hydrochloride and osimertinib could be effective for non-small cell lung cancer?

Research has shown that osimertinib effectively treats non-small cell lung cancer with specific changes in the EGFR gene. It outperforms earlier treatments by extending the time patients live without cancer progression and by increasing overall survival. In this trial, researchers are studying the combination of telaglenastat hydrochloride and osimertinib to determine if it can further enhance these outcomes. This combination might work by blocking enzymes necessary for cancer cell growth, potentially preventing tumor progression. Early study results suggest this combination could be a promising treatment option for patients with this type of lung cancer. ^{6 7 8 9 10}

Are You a Good Fit for This Trial?

Adults over 18 with stage IV non-small cell lung cancer and specific EGFR gene mutations, who have had disease progression after prior EGFR inhibitor therapy. They must be able to swallow pills, have a life expectancy over 3 months, and meet certain blood count and organ function criteria. Excluded are those with significant cardiovascular history, other active malignancies at high risk of relapse, uncontrolled illnesses or infections like HIV.

Inclusion Criteria

You have enough white blood cells called neutrophils.

Your platelet count is at least 100,000 per microliter.

Your total bilirubin level needs to be within a certain range, unless you have Gilbert's disease. If you have Gilbert's disease, your bilirubin level can be slightly higher.

Exclusion Criteria

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 psychiatric illness/social situations that would limit compliance with study requirements

I have NSCLC and no other active cancers, except for certain low-risk or localized types.

Trial Overview

The trial is testing the combination of Telaglenastat Hydrochloride and Osimertinib for safety and optimal dosage in patients with advanced lung cancer harboring EGFR mutations. It aims to see if these drugs can block enzymes necessary for tumor growth.

How Is the Trial Designed?

Group I: Treatment (telaglenastat HCl, osimertinib) Experimental Treatment 7 Interventions

Patients receive telaglenastat hydrochloride PO BID and osimertinib PO QD (starting cycle 1 day 16 of phase I). Patients undergo blood sample collection and may undergo x-ray imaging, CT scan, MRI, or PET scan throughout the study. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
