Phase 2 Study of Fingolimod in Lung Cancers

A Phase II Study of Fingolimod in Patients With Non-Small Cell and Small Cell Lung Cancer

This is a single-institution, open-labeled study using fingolimod (FTY720/Gilenya) in patients with non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) who have progressed on chemo-immunotherapy. The study design will be a 6 patient safety lead-in with 2 cohorts of patients for efficacy analysis where fingolimod 0.5 mg will be taken orally once daily.

Study Overview

• Status: Recruiting
• Conditions: Non Small Cell Lung Cancer; Small-cell Lung Cancer
• Intervention / Treatment: Drug: Fingolimod 0.5 milligram (mg) [Gilenya]

Detailed Description

Lung cancer is the second most common cancer and the leading cause of cancer death in the United States. There were approximately 237,000 new cases of lung cancer that were diagnosed in 2022 . The past decade has seen a revolution of new advances in the management of both non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) with remarkable progress in screening, diagnosis, and treatment. The advances in systemic treatment have been driven primarily by the development of molecularly targeted therapeutics, immune-checkpoint inhibitors, and anti-angiogenic agents, all of which have transformed this field with significantly improved patient outcomes. Despite these advances, the prognosis for patients with advanced NSCLC and SCLC is poor, particularly after the failure of a platinum-based chemotherapy regimen and check point inhibitors with limited options available for patients. Therefore, new methods of targeting these malignancies are crucial. Fingolimod is a sphingosine analog that has demonstrated strong tumor suppressive activity in preclinical models of lung cancers and warrants further study.

This proposed study is a single institution Phase II clinical trial to investigate the safety and efficacy of fingolimod in patients with NSCLC and SCLC. Fingolimod is a small molecule derived from myriocin that acts as a sphingosine analog. It is currently FDA-approved to treat patients with relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease by binding to sphingosine-1-phosphate (S1P) receptors 1, 3, 4, and 5 causing T lymphocyte egression and retention in peripheral lymphoid organs leading to immunosuppression. However, it can act as an antagonist for the S1P receptor promoting tumor suppression in multiple cancer cell lines and mouse models inhibiting cell proliferation, and inducing cancer cell death. There are multiple studies demonstrating its activity in preclinical models of lung cancer. Fingolimod induces a type of programmed cell death called necroptosis in lung cancer cells. This is mediated by activation of the tumor suppressor protein phosphatase 2A (PP2A) through interaction with the PP2A inhibitor (I2PP2A). Specifically, work done using the adenocarcinoma cell line A549 and small cell carcinoma cell line H1341 showed that fingolimod-mediated stress induced the formation of ceramidosomes leading to plasma membrane blebbing, compromised membrane integrity, and necroptosis.

This study will evaluate the safety, tolerability, and response rate in patients with NCSLC and SCLC who have progressed on front-line therapy including chemotherapy, immune checkpoint inhibitors, and targeted agents. It will contribute to the development of new methods for targeting these malignancies and provide insights into the potential use of fingolimod as a treatment option for these patients.

Inclusion Criteria:

• Voluntary, signed, and dated, Institutional Review Board (IRB) approved consent form in accordance with regulatory and institutional guidelines.
• Stated willingness to comply with all study procedures and availability for the duration of the study.
• Male or female
• 18 years of age or older
• Measurable/evaluable as defined by RECIST 1.1 at baseline of advanced/metastatic non-small cell lung cancer progressed on 2L+ systemic therapy with any molecular subtype and PD-L1 Tumor Proportion Score (TPS).
• Measurable/evaluable as defined by RECIST 1.1 at baseline of extensive stage small cell lung cancer progressed on 2L+ systemic therapy.
• Ability to take oral medication and be willing to adhere to the fingolimod regimen.
• ECOG performance status 0-2
• Baseline lymphocyte count >1000 cells/mL
• For females of reproductive potential: use of highly effective contraception for at least 1 month before screening and agreement to use such a method during study participation and for an additional 2 months after the end of fingolimod administration.
• For males of reproductive potential: use of condoms or other methods during and for an additional 2 months after the end of fingolimod treatment to ensure effective contraception with a partner.

Exclusion Criteria:

• Patients who have had a recent (within the last 6 months) occurrence of cardiac event including myocardial infarction, unstable angina, stroke, transient ischemic attack, decompensated heart failure requiring hospitalization, or New York Heart Association Class III or IV heart failure, and congenital long QT-syndrome
• Patients who are receiving any medication(s) identified as having a Category D or higher interaction with the identified study agent who cannot be switched to another agent or discontinued before treatment if clinically appropriate. This medication review will be conducted by an oncology-trained Doctor of Pharmacy and discussed with the investigators before starting the treatment phase of this study. Careful evaluation for the following class of medications should be warranted due to their potential for severe side effects:
• Concurrent therapy with QT-prolonging medications with a known risk of torsade de pointes
• Concurrent therapy with drugs that slow heart rate or atrioventricular conduction
