Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Neoplastic meningitis refers to the deposition of malignant cells in the lining (leptomeninges) of the brain and spine. Neoplastic meningitis from solid tumors most often occurs in patients with advanced systemic disease who have failed prior chemotherapy; it is also frequent in patients with CNS parenchymal metastasis. Patient survival remains low, and better treatments are needed to penetrate the blood brain barrier and treat the entire neuraxis.

RTA 744 is a close chemical analogue of the well characterized anti-cancer agent doxorubicin. Unlike doxorubicin, RTA 744 has shown ability to cross the blood brain barrier and to achieve high concentration in CNS tumor tissue in animal models. Dose escalation will continue as pre-determined until first occurrence of a dose-limiting toxicity. Maximum tolerated dose will be determined as defined in protocol.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Determine the tolerability of RTA 744 Injection in patients with leptomeningeal disease (LMD) secondary to any type of primary tumor.
Time Frame: evaluation at end of cycle 1 for each cohort
evaluation at end of cycle 1 for each cohort
Characterize the multiple-dose pharmacokinetics of RTA 744 in plasma and CSF in a selected group of 6-10 patients who will receive RTA 744 at or near the maximum tolerated dose (MTD).
Time Frame: end of study
end of study

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Document any potential antitumor activity.
Time Frame: after every even numbered treatment cycle
after every even numbered treatment cycle
Correlate pharmacokinetic information with clinical (efficacy and safety) responses.
