Pembrolizumab and Magnetic Resonance Imaging With Ferumoxytol in Treating Patients With Non-small Cell Lung Cancer and Brain Metastases

• Status: Terminated
• Trial end date: 2021-03-01
• Target enrollment: 0
• Participant gender: All

Summary

This pilot phase II trial study evaluates the usefulness of the ferumoxytol steady state magnetic resonance imaging (MRI) technique for response assessment after pembrolizumab and radiation therapy in non-small cell lung cancer that has spread to the brain (brain metastases). The interactions of monoclonal antibodies such as pembrolizumab, and the body's immune system may result in an anti-tumor effect. However, it may also increase inflammation around the tumor which cannot be differentiated from true tumor growth on standard MRI. This study evaluates ferumoxytol as an MRI contrast agent to differentiate this treatment related inflammation from true tumor growth.

• Albumin >= 2.5 mg/dL

• International normalized ratio (INR) or prothrombin rime (PT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants

• Activated partial thromboplastin time (aPTT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants

• Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours 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

• Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication; subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year; male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy

Exclusion Criteria:

• Has evidence of leptomeningeal disease on MRI or in cerebrospinal fluid (CSF)

• If tumor demonstrates EGFR or ALK genomic tumor aberrations, subject should have documented disease progression on FDA-approved therapy for these aberrations

• Has a diagnosis of immunodeficiency and is not on continuous daily immunosuppressive therapy within 7 days prior to the first dose of trial treatment; (subjects may receive steroids before or after SRS to prevent or manage cerebral edema; inhalational steroids are permitted)

• Has previously progressed on a PD-1 or PD-L1 checkpoint inhibitor for systemic disease

• Has a known history of active TB (Bacillus tuberculosis)

• Has hypersensitivity to pembrolizumab, gadolinium, or ferumoxytol or any of their excipients

• Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier

• Note: The use of denosumab is an exception to this criterion

• Subject who has not recovered (i.e., =< grade 1 or at baseline) from adverse events due to a previously administered agent

• Note: Subjects with =< grade 2 neuropathy are an exception to this criterion and may qualify for the study

• Note: Subjects with =< grade 2 hematologic toxicities are an exception to this criterion and may qualify for the study

• Note: Subjects with =< grade 2 fatigue are an exception to this criterion and may qualify for the study

• Has a known additional malignancy that is progressing or requires active treatment; exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer

• Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs); replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment

• Has known history of, or any evidence of active, non-infectious pneumonitis
