A Study of IMPT-514 in Active Refractory Systemic Lupus Erythematosus (SLE)

Study Purpose

This is a Phase 1/2, multi-center, open-label study evaluating the safety and efficacy of IMPT-514, a bispecific chimeric antigen receptor (CAR) targeting cluster of differentiation (CD)19 and CD20 in participants with active, refractory lupus nephritis and systemic lupus erythematosus. IMPT-514 treatment consists of a single infusion of CAR-transduced autologous T cells administered intravenously after a lymphodepleting therapy regimen consisting of fludarabine and cyclophosphamide. Individual participants will remain in the active post-treatment period for approximately 1 year. Participants will continue in long-term follow-up for 15 years from treatment.

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT06153095
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
