Pemetrexed Disodium in the Cerebrospinal Fluid of Patients With Leptomeningeal Metastases

September 3, 2021 updated by: Northwestern University

A Pharmacokinetic Study of Pemetrexed in the Cerebrospinal Fluid of Patients With Leptomeningeal Metastases

RATIONALE: Pemetrexed disodium may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Studying samples of cerebrospinal fluid and blood from patients with cancer in the laboratory may help doctors learn how pemetrexed disodium works in the body and identify biomarkers related to cancer.

PURPOSE: This clinical trial is studying the side effects and how well pemetrexed disodium works in treating patients with leptomeningeal metastases.

Detailed Description

OBJECTIVES:

  • Determine the cerebrospinal fluid (CSF):plasma ratio of pemetrexed disodium at different IV dose levels in patients with leptomeningeal metastases.
  • Determine the safety of this drug in these patients.
  • Determine the antitumor activity of this drug in these patients.
  • Assess the role of CSF vascular endothelial growth factor and YKL 40 as markers of response and/or prognosis in these patients.

OUTLINE: Patients receive pemetrexed disodium IV over 10 minutes on day 1. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity.

Patients undergo lumbar puncture and blood collection prior to therapy and 30-60 minutes after the first dose of pemetrexed disodium for pharmacological studies. Patients with Ommaya reservoirs undergo cerebrospinal fluid (CSF) collection at baseline and 0.25, 0.50, 1, 2, 4, 6 and 8.0 hours after pemetrexed disodium administration. CSF is then obtained once during each subsequent course of study treatment. CSF and blood are also evaluated for YKL 40 and vascular endothelial growth factor.

After completion of study therapy, patients are followed every 2-3 months.

PROJECTED ACCRUAL: A total of 15 patients will be accrued for this study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
