Prospective Evaluation Of Delayed Effects Of Pediatric Car T Cell Therapy

Not yet recruiting

• Conditions: B-ALL; Hematologic Malignancy; Solid Tumor

• Registration Number: NCT06579469
• Lead Sponsor: St. Jude Children's Research Hospital

Brief Summary

This study is being done to learn more about the short-term and long-term side effects of CAR-T cell therapy. Specifically, researchers want to know how often patients get infections, have delays in recovering blood cell counts and/or have damage to the nervous system.

Detailed Description

Primary Objectives

* Bone Marrow Function: To report on the incidence, timing, severity of, and risk factors for bone marrow dysfunction in participants in remission or without bone marrow involvement of disease at 3- and 6-months following CAR T cell therapy. (B-ALL cohort)

Primary Outcome Measures

Name	Time	Method
Presence of bone marrow dysfunction (BMD)	Within 6 months post CAR T-cell therapy	Among patients in remission or without bone marrow involvement of disease in the B-ALL cohort, we will summarize the rates of prevalent BMD at 3- and 6-months post-infusion and estimate the cumulative incidence of new BMD and BMD recovery for patients with prevalent BMD at 3- and 6-months.
Occurrence of clinically significant infections	Within 6 months post CAR T-cell therapy	The infection density of clinically significant infections in 3-6 months will be summarized in the B-ALL cohort.
Presence of persistent ICANS	Within 6 months post CAR T-cell therapy	We will summarize the rates of persistent ICANS at 3- and 6-months post-infusion and estimate the cumulative incidence and timing of new ICANS and ICANS recovery for patients with persistent ICANS at 3- and 6-months in the B-ALL cohort.

Secondary Outcome Measures

Name	Time	Method
Severity of clinically significant infections	Within 24 months post CAR T-cell therapy	The highest severity among all clinically significant infections for each patient will be summarized. The severity of clinically significant infections in the B-ALL cohort will be described. Analyses will be replicated in the other hematologic malignancies and solid tumor cohorts.
Presence of bone marrow dysfunction (BMD)	Within 24 months post CAR T-cell therapy	Among patients in remission or without bone marrow involvement of disease in the B-ALL cohort, we will summarize the rates of prevalent BMD at 12- and 24-months post-infusion and estimate the cumulative incidence of new BMD and BMD recovery for patients with prevalent BMD at 12- and 24-months. Analyses will be replicated in the other hematologic malignancies...
Severity of BMD	Within 24 months post CAR T-cell therapy	The highest severity BMD for each patient will be recorded. The severity of BMD in the B-ALL cohort will be described using descriptive statistics. Analyses will be replicated in the other hematologic malignancies and solid tumor cohorts.
Occurrence of clinically significant infections	Within 24 months post CAR T-cell therapy	The infection density of clinically significant infections within 24 months will be summarized in the B-ALL cohort. Analyses will be replicated in the other hematologic malignancies and solid tumor cohorts.
Time to the earliest clinically significant infection	Within 24 months post CAR T-cell therapy	The time from 3 months post-infusion to the first clinically significant post-infusion within 24 months post-infusion will be summarized in the B-ALL cohort. The cumulative incidence of the first clinically significant infection post-infusion within 24 months will be estimated in B-ALL cohort. Analyses will be replicated in the other hematologic malignancies...
Presence of persistent ICANS	Within 24 months post CAR T-cell therapy	We will summarize the rates of persistent ICANS at 12- and 24-months post-infusion and estimate the cumulative incidence and timing of new ICANS and ICANS recovery for patients with persistent ICANS at 12- and 24-months in B-ALL cohort. Analyses will be replicated in the other hematologic malignancies and solid tumor cohorts.
Severity of persistent ICANS	Within 24 months post CAR T-cell therapy	The highest severity of ICANS for each patient will be recorded. The severity of ICANS in the B-ALL cohort will be described using descriptive statistics. Analyses will be replicated in the other hematologic malignancies and solid tumor cohorts.
