About this study

Official title: A Phase I Study of Autologous Activated T-cells Targeting the CD19 Antigen and Containing the Inducible Caspase 9 Safety Switch in Subjects With Relapsed/Refractory B-cell Lymphoma

This research study combines 2 different ways of fighting disease: antibodies and T cells. Both antibodies and T cells have been used to treat patients with cancers, and both have shown promise, but neither alone has been sufficient to cure most patients. This study combines both T cells and antibodies to create a more effective treatment. The treatment being researched is called autologous T lymphocyte chimeric antigen receptor cells targeted against the CD19 antigen (ATLCAR.CD19) administration.

Prior studies have shown that a new gene can be put into T cells and will increase their ability to recognize and kill cancer cells. The new gene that is put in the T cells in this study makes a piece of an antibody called anti-CD19. This antibody sticks to leukemia cells because they have a substance on the outside of the cells called CD19. For this study, the anti-CD19 antibody has been changed so that instead of floating free in the blood part of it is now joined to the T cells. When an antibody is joined to a T cell in this way it is called a chimeric receptor. These CD19 chimeric (combination) receptor-activated T cells seem to kill some of the tumor, but they do not last very long in the body and so their chances of fighting the cancer are unknown.

Preliminary results have shown that subjects receiving this treatment have experienced unwanted side effects including cytokine release syndrome and neurotoxicity. In this study, to help reduce cytokine release syndrome and/or neurotoxicity symptoms, the ATLCAR.CD19 cells have a safety switch that, when active, can cause the cells to become dormant. These modified ATLCAR.CD19 cells with the safety switch are referred to as iC9-CAR19 cells. If the subject experiences moderate to severe cytokine release syndrome and or neurotoxicity as a result of being given iC9-CAR19 cells, the subject can be given a dose of a second study drug, AP1903, if standard interventions fail to alleviate the symptoms of cytokine release syndrome and/or neurotoxicity. AP1903 activates the iC9-CAR19 safety switch, reducing the number of the iC9-CAR19 cells in the blood. The ultimate goal is to determine what dose of AP1903 can be given that reduces the severity of the cytokine release syndrome and/or neurotoxicity, but still allows the remaining iC9-CAR19 cells to effectively fight the lymphoma.

The primary purpose of this study is to determine whether receiving iC9-CAR19 cells is safe and tolerable in patients with relapsed/refractory B-cell lymphoma, primary central nervous system lymphoma and chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL).

Read the detailed description

This study is a phase I dose finding trial to determine if chimeric antigen receptor T (CAR-T) cells targeting the CD19 antigen and containing the inducible caspase 9 safety switch can be safely administered to adult subjects with relapsed or refractory B-cell Lymphoma, primary central nervous system lymphoma and chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). The safety of iC9-CAR19 cells will be investigated using the 3+3 design. The starting dose of 1 x 106 transduced cells/kg (dose level 1) will enroll at least 3 subjects in the initial cohort. If there are no dose limiting toxicities (DLTs) within 4 weeks of the cell infusion in these 3 subjects, then the next cohort will evaluate 2 x 106 transduced cells/kg. If there is toxicity in 1/3 subjects in the initial cohort, the cohort will be expanded to enroll up to 6 subjects. During iC9-CAR19 T cell dose exploration, rimiducid (0.4 mg/kg), a dimerizing agent that is designed to engage and activate the caspase 9 safety switch to trigger iC9-CAR19 T cell death by apoptosis will be given to subjects who develop grade 4 cytokine release syndrome (CRS) or grade ≥3 CRS that is unresponsive to standard of care interventions, and to subjects who develop grade ≥3 Immune effector cell-associated neurotoxicity syndrome ( ICANS) that does not improve to grade ≤1 within 72 hours with standard of care interventions, and subjects with grade 4 ICANS of any duration that have evidence of cerebral edema and/or generalized convulsive status epilepticus. After the tolerable cell dose (TCD) of iC9-CAR19 T cells has been determined, up to 18 additional adult subjects may be enrolled in an expansion cohort at the TCD. Rimiducid will be given to subjects in the expansion cohort who develop grade ≥3 immune effector cell-associated neurotoxicity syndrome (ICANS) that does not improve to grade ≤1 within 72 hours with standard of care interventions, and subjects with grade 4 ICANS of any duration that have evidence of cerebral edema and/or generalized convulsive status epilepticus. Subjects in the expansion cohort who experience ≥grade 2 CRS or ICANS that remains ≥grade 2 twenty-four hours after initial standard of care treatment (tocilizumab for CRS or steroids for ICANS) may be part of the rimiducid sub-study. These subjects will receive one of two assigned dose levels of rimiducid with their second standard of care treatment. The percent reduction in CAR T cells will be measured in these subjects. If the subjects' CRS or ICANS is unresponsive to standard treatment and the assigned dose level of rimiducid, subjects with ≥grade3 CRS or ICANS will then be given a full dose (0.4 mg/kg) of rimiducid. If the subject's CRS or ICANS is at grade 2 48 hours after the first dose of rimiducid, they will receive another dose of rimiducid at the assigned dose level.

Cell Procurement Peripheral blood, up to 300 mL (in up to 3 collections) will be obtained from subjects for cell procurement. In subjects with inadequate lymphocyte count in the peripheral blood, a leukapheresis may be performed to isolate sufficient T cells. The parameters for apheresis will be up to 2 blood volumes.

Lymphodepleting Regimen Subjects will receive a "pre-conditioning" cytoreductive regimen of bendamustine 70 mg/m2/day administered IV followed by an IV dose of fludarabine 30 mg/m2/day administered over 3 consecutive days. These agents will be administered per institutional guidelines. Prophylaxis (e.g., hydration, antiemetics, etc.) needed prior to fludarabine and bendamustine chemotherapy will be provided per institutional guidelines. At the discretion of the clinical investigator, subjects with a known history of intolerance to bendamustine may be considered for lymphodepletion with cyclophosphamide 500 mg/m2/day administered by IV followed by an IV dose of fludarabine 30 mg/m2/day administered over 3 consecutive days. These agents will be administered per institutional guidelines.

Administration of iC9-CAR19 T cells Post lymphodepletion, subjects who meet eligibility criteria for cellular therapy will receive iC9-CAR19 T cells within 2 - 14 days after completing the lymphodepleting chemotherapy regimen. Post lymphodepletion iC9-CAR19 will be administered at dose levels specified in the protocol. A recently published trial in refractory DLBCL established that a dose of 2 x 10 6 CAR19+ T cells/kg was safe and associated with significant in vivo expansion and we anticipate similar results with iC9-CAR19+ T cells.

Duration of Therapy Therapy in this study involves 1 infusion of iC9-CAR19 cells.

Duration of Follow-up Subjects who receive a cell infusion will be followed for up to 15 years for replication-competent retrovirus evaluation or until death, whichever occurs first. Subjects who are removed from study and do not receive the cellular therapy product due to unacceptable adverse events will be followed until resolution or stabilization of the adverse event.

  7. Change in Patient-reported Symptoms

    Patient reported symptoms will be measured using selected symptoms from the NCI Patient Reported Outcomes-Common Terminology Criteria for Adverse Events (PRO-CTCAE). The PRO-CTCAE is a patient-reported outcome measurement system developed to characterize the frequency, severity and interference of symptomatic treatment toxicities. Each of the symptom terms included in the PRO-CTCAE is assessed relative to one or more distinct attributes, including presence/absence, frequency, severity, and/or interference with usual or daily activities. Responses are provided on a 5-point Likert scale: Frequency item: How OFTEN did you have? (Never / Rarely / Occasionally / Frequently / Almost constantly); Severity item: What was the SEVERITY of your at its WORST? (None / Mild / Moderate / Severe / Very severe);Interference item: How much did INTERFERE with your usual or daily activities? (Not at all / A little bit / Somewhat / Quite a bit / Very much)

    Measured: 1 year

  8. Change in Physical Function

    The Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function Short Form 20a v1.0. assesses one's ability to carry out activities that require physical actions, ranging from self-care (activities of daily living) to more complex activities that require a combination of skills, often within a social context. "Physical Function" is inclusive of the term "disability" and includes the full spectrum of physical functioning from severe impairment to exceptional physical abilities. Each question has five response options ranging in value from one to five, resulting in a total score (T-score) from 0 to 100. A higher PROMIS T-score represents more of the concept being measured. For positively-worded concepts like Physical Function, a T-score of 60 is one SD better than average. By comparison, a Physical Function T-score of 40 is one SD worse than average.

    Measured: 1 year

  9. Change in Health Related Quality of Life

    The Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health measures assess an individual's physical, mental, and social health. The measures are generic, rather than disease-specific, and often use an "In General" item context as it is intended to globally reflect individuals' assessment of their health. Each question has five response options ranging in value from one to five, which are summed into T-score values for physical and mental health. A higher PROMIS T-score represents more of the concept being measured. Thus, a person who has T- scores of 60 for the Global Physical Health or Global Mental Health scales is one standard deviation better (more healthy) than the general population.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing iC9-CAR19 T cells, Bendamustine and Fludarabine in people with Lymphoma and Lymphoma, B-Cell, run by UNC Lineberger Comprehensive Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 37 inclusion and 40 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 31 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 31 Jul 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment-emergent Grade ≥ 3 Adverse Events Per National Cancer Institute's Common Terminology Criteria (time frame: Up to 4 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03696784.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jul 2026.
