This protocol is designed as a long-term follow-up study of participants who will receive CAR-T cells as part of a clinical trial at the Medical College of Wisconsin/ Froedtert Hospital. The clinical trials include the following:

Phase 1 Study of CAR-20/19-T Cells in Patients with Relapsed Refractory B Cell Malignancies (NCT03019055); Phase I Trial of BCMA-TGF-BETA CAR-T Cells in Relapsed, Refractory Myeloma (NCT05976555); CAR20.19.22 T-cells in Relapsed, Refractory B-cell Malignancies (NCT05094206); LV20.19 CAR T-Cells in Combination With Pirtobrutinib for Relapsed, Refractory B-cell Malignancies (NCT05990465); CAR-20/19-T Cells in Patients With Relapsed Refractory B Cell Malignancies (NCT04186520)

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

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 objective is to follow participants receiving CAR-T cells from years 2 to 15 post-treatment for persistence of CAR-T cells, development of secondary malignancies, or other medical complications.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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 to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

All participants who enrolled in a CAR-T study at Froedtert Hospital & the Medical College of Wisconsin.

Description

Inclusion Criteria:

  • All participants who enrolled in a CAR-T study at Froedtert Hospital & the Medical College of Wisconsin.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Participants who received CAR-T cells.
Participants who received CAR-T cells at Froedtert Hospital & the Medical College of Wisconsin in clinical trials (e.g., NCT05976555, NCT05094206, NCT05990465, NCT03019055 or NCT04186520).
Other: Long-Term Follow-Up of Participants who Received CAR-T cells

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
Measure Description
Time Frame
Change from baseline in the incidence of a new malignancy at 5 years.
Time Frame: Baseline to five years.
The number of subjects with new malignancy.
Baseline to five years.
Change from baseline in the incidence of a new malignancy at 10 years.
Time Frame: Baseline to 10 years.
The number of subjects with new malignancy.
Baseline to 10 years.
Change from baseline in the incidence of a new malignancy at 15 years.
Time Frame: Baseline to 15 years.
The number of subjects with new malignancy.
Baseline 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.
Outcome Measure
Measure Description
Time Frame
Change from baseline in the number of participants who are disease free two years post-infusion.
Time Frame: Two years post-infusion.
The number of subjects who relapse or progress among subjects who are disease free two years post-transplant.
Two years post-infusion.
Change from baseline in overall survival rate.
Time Frame: Every 6 months from years 2-5 post-infusion then yearly from year 6-15.
The number of subjects who are alive.
Every 6 months from years 2-5 post-infusion then yearly from year 6-15.
Change from baseline in the absolute B- and T-lymphocyte counts.
Time Frame: Every 6 months from years 2-5 post-infusion then yearly from year 6-15.
The number of cells measured by 10^3 cells/µL.
Every 6 months from years 2-5 post-infusion then yearly from year 6-15.
Change from baseline in the proportion of participants with persistent CAR-20/19-T cells.
Time Frame: Every 6 months from years 2-5 post-infusion then yearly from year 6-15.
The number of participants with persistent cells measured by by integrated vector DNA by quantitative polymerase chain reaction.
Every 6 months from years 2-5 post-infusion then yearly from year 6-15.
Change from baseline in the recovery of immunoglobulin production as measured by quantitative immunoglobulin levels.
Time Frame: Every 6 months from years 2-5 post-infusion then yearly from year 6-15.
This measure will be the serum concentration of Immunoglobin A (IgA), immunoglobin G (IgG) and immunoglobin M (IgM).
Every 6 months from years 2-5 post-infusion then yearly from year 6-15.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
