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

The study creates autologous gene-modified T cells against prostate specific membrane antigen (PSMA, unrelated to PSA) (designer T cells) by ex vivo modification of patient T cells. T cells are collected by leukopheresis, transported to the RWMC cGMP Cell Manipulation Core and transduced with retrovirus containing a chimeric antigen receptor (CAR) that is expressed on the modified cells. This CAR links specificity of an antibody against PSMA with signaling domains of the T cell and redirects the recognition of the T cells to engage and kill prostate cancer cells anywhere in the body. These are administered at a dose of 10^10 with randomization to either low or moderate Interleukin 2 given by CI (continuous infusion) for one month following the T cell infusion. Subsequent subjects will receive 10^11 cells with Interleukin 2 at either low or moderate dose, in a non randomized manner, depending upon the outcome of the prior cohort. Prior to T cell infusion, all subjects will receive non-myeloablative (NMA) conditioning. This conditioning creates a "space" in the blood and marrow for engraftment of the infused cells to maintain of high level of anti-tumor effector T cells in the body. Each patient is treated with a single dose of T cells, without repeat dosing. Patients are followed for toxicity and response and pharmacokinetics-pharmacodynamics of the infused T cells. Patients are on-study for one-month after their T cell dose.

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.

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

Time Frame: 1 Month
1 Month

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.
