Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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 purpose of this study is to monitor all patients exposed to an AUTO CAR T cell therapy, for up to 15 years following their first AUTO CAR T cell therapy infusion to assess the risk of delayed treatment-related SAEs, adverse events of special interest (AESIs), monitor for emergence of replication competent retrovirus (RCR) or replication competent lentivirus (RCL), monitor for the emergence of a new malignancy associated with insertional mutagenesis (insertion site analysis), assess CAR transgene persistence and assess long-term efficacy. Monitoring of such long-term effects of AUTO CAR T cell therapy will help to further define the risk-benefit profile of these new CAR T cell therapies.

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

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.

Time Frame: For up to 15 years

Monitoring of all SAEs / AESIs, including any new malignancy or new diagnosis of neurologic disorders, or other hematologic disorder, related to AUTO CAR T cell therapy.

Monitoring of all adverse events of special interest related to AUTO CAR T cell therapy infusion.
For up to 15 years

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.
