Active clinical trials for "Meningeal Neoplasms"

The purpose of this study is to find out how well an experimental drug called DepoCyt works for neoplastic meningitis (cancer that has spread to the tissues around the brain and spinal cord). DepoCyt is a new slow-release form of the cancer drug called ara-C (cytarabine). Cytarabine has been used for many years to treat cancer.

This research study is an investigational treatment with the experimental drug Mafosfamide. This treatment is only for children with cancer that has spread to the meninges (tissues that cover the spinal column and brain) and has continued to grow despite treatment with standard therapy. Mafosfamide is a drug reported to have antitumor effects in animals and that has been given safely into the cerebrospinal fluid (the fluid within and surrounding the brain) in a small number of children and adults. Since there is limited experience in adults and children in giving mafosfamide in this way, the main purpose of this study is to determine the appropriate safe dose of mafosfamide when given intrathecally, that is directly into the cerebrospinal fluid. The purposes for this study are to (a) determine what dose of mafosfamide can be safely given into the cerebrospinal fluid through an Ommaya reservoir (surgically implanted catheters used to sample cerebrospinal fluid and to instill medication into the cerebrospinal fluid) and lumbar puncture (spinal tap) or lumbar reservoir; (b) look for side effects of drug treatment; (c) to study the pharmacology (how the human body handles the drug) when given directly into the spinal fluid; and (d) see if this drug is beneficial to the patient.

The purpose of this study is to determine efficacy of intrathecal mafosfamide, a preactivated derivative of cyclophosphamide against meningeal malignancies refractory to conventional therapy (radiation therapy and chemotherapy). The maximally tolerated dose for intrathecal mafosfamide will be established in a limited dosage escalation schedule. The CSF pharmacokinetics of intrathecal mafosfamide will also be studied. Mafosfamide will be administered intrathecally on a bi-weekly basis for four weeks, followed by twice monthly administration for four months and then monthly IT administration. A minimum of 9 patients will be studied in each disease category (leukemias, lymphomas, and other malignancies refractory to conventional therapy).

The purpose of this study is to determine the qualitative and quantitative toxicity of intrathecal topotecan, a topoisomerase I inhibitor, in patients with meningeal malignancies refractory to conventional therapy (radiation therapy and chemotherapy).

The FORESEE Study is a multi-center, prospective clinical trial enrolling patients with Breast or Non-Small Cell Lung Cancer (NSCLC) who have suspicious or confirmed Leptomeningeal Metastases (LM). Standard of Care methods to diagnose, or assess the treatment response of LM (Clinical Evaluation, MRI and Cytology) have limited sensitivity and specificity. This creates challenges for physicians to manage LM or determine the best course of treatment. CNSide, is a Laboratory Developed Test (LDT ) that is used commercially at the Physician's discretion in Biocept's CLIA certified, CAP accredited laboratory. CNSide can detect and quantify tumor cells in the CSF from patients with Breast Cancer or NSCLC having a suspicious or confirmed LM. The goal of the FORESEE Study is to evaluate the performance of CNSide in monitoring the LM's response to treatment and to assess the impact of CNSide on treatment decisions made by Physicians.

The researchers are doing this study to provide access to treatment with 131I-omburtamab for children and young adults who have CNS/leptomeningeal neoplasms. 131I-omburtamab is an investigational drug; the FDA has not approved it to treat this cancer or any other disease. However, the agency has granted the drug Breakthrough Therapy Designation for the treatment of neuroblastoma with CNS metastases.
