- Brief Summary
This is a global, open-label, multi-arm, parallel multi-cohort, multi-center, Phase 1/2 study to determine the safety, tolerability, PK, efficacy and patient-reported quality of life of JCAR017 in combination with various agents. This protocol is intended to evaluate various drug combinations with JCAR017, as separate arms, over the life of the protocol, using the same objectives. Each combination will be evaluated separately (ie, the intention is not to compare between combinations) for the purposes of the objectives, trial design, and statistical analysis. The following combinations will be tested:
Arm A: JCAR017 in combination with durvalumab Arm B: JCAR017 in combination with CC-122 (avadomide) Arm C: JCAR017 in combination with CC-220 (iberdomide) Arm D: JCAR017 in combination with ibrutinib Arm E: JCAR017 in combination with relatlimab and/or nivolumab Arm F: JCAR017 in combination with CC-99282 Additional arms will be added by way of amendment once combination agents have been selected.
The study will consist of 2 parts: dose finding (Phase 1) and dose expansion (Phase 2). Dose expansion may occur in one or more arms.
- Detailed Description
During Phase 1, different arms may be opened to test JCAR017 in combination with combination agent(s) in adult subjects with R/R aggressive B-cell NHL. Within each arm, different doses and schedules of JCAR017 and the combination agent(s) may be tested in several cohorts and subcohorts per arm. During Phase 2 of the study, the expansion of any dose level and schedule for any arm that has been shown to be safe may occur.
Arm A will test JCAR017 in combination with Durvalumab Arm B will test JCAR017 in combination with CC-122 Arm C will test JCAR017 in combination with CC-220 (iberdomide ) Arm D will test JCAR017 in combination with ibrutinib. Arm E will test JCAR017 in combination with relatlimab and/or nivolumab Arm F will test JCAR017 in combination with CC-99282 All subjects from Phase 1 and Phase 2 will be followed for 24 months following JCAR017 infusion. Post-study follow-up for survival, relapse, long-term toxicity (including new malignancies), and viral vector safety will continue under a separate long-term follow-up (LTFU) protocol for up to 15 years after the JCAR017 dose as per health authority regulatory guidelines.

Maximum Concentration (Cmax) of JCAR017 by qPCR Up to 24 months post- JCAR017 infusion Cmax is the maximum or peak concentration of drug reached in the plasma following a dose of the drug.
qPCR was used to determine Cmax by detecting the JCAR017 transgene.Time to Maximum Concentration (Tmax) of JCAR017 by qPCR Up to 24 months post- JCAR017 infusion Time to maximum concentration (Tmax) is the time it takes for a drug to reach the maximum concentration (Cmax) after administration.
qPCR was used to determine Tmax by detecting the JCAR017 transgene.European Organisation for Research and Treatment of Cancer - Quality of Life C30 Questionnaire (EORTC QLQ-C30) Scores - Phase 2 At baseline and 29 days and 57 days post JCAR017 dose The EORTC QLQ-C30 is composed of five functional scales (physical, role, emotional, cognitive and social), three symptom scales (fatigue, nausea/vomiting, and pain), a global health status/health-related quality of life (HRQoL) scale, and six single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). The questionnaire is scored on a 4-point Likert response scale: 1 = not at all, 2 = a little, 3 = quite a bit, and 4 = very much.
The raw score is calculated as the average of the items that contribute to the scale. The final scores are calculated via linear transformation of raw scores and range from 0 to 100.
For functional scales (physical, role, emotional, social, cognitive and global health) higher scores indicate better QoL.
For symptom scales (fatigue, nausea and vomiting and pain) and single items (dyspnea, insomnia, appetite loss, constipation, diarrhea and financial difficulties) lower scores indicate fewer symptoms, i.e. better QoL.EuroQol- 5 Dimensions of Health Visual Analogue Scale (EQ-5D VAS) Scores - Phase 2 At baseline and 1, 29, 57, 85, 180, 270, 365, 545, and 730 days post JCAR017 dose The EuroQol- 5 Dimensions of Health Visual Analogue Scale (EQ-5D VAS) records the participant's self-rated health on a vertical visual analogue scale, where the endpoints are scored from 0 to 100 i.e., 'The worst health you can imagine' (score of 0) to 'The best health you can imagine' (score of 100). Higher scores indicate better health outcomes.
Number of Participants With Adverse Events (AEs) Up to 3 months after the dose of JCAR017 or after the last dose of the combination agent, whichever occurred last (an average of 6.5 months up until a max of 9.5 months) An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a participant during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the participant's health, including laboratory test values, regardless of etiology. Any worsening (i.e., any clinically significant adverse change in the frequency or intensity of a preexisting condition) is also considered an AE. All participants were monitored for AEs during the study. Assessments included monitoring of any or all of the following parameters: the participant's clinical symptoms, laboratory, pathological, radiological or surgical findings, physical examination findings, or findings from other tests and/or procedures.
Number of Participants With Severe Adverse Events (SAEs) Up to 3 months after the dose of JCAR017 or after the last dose of the combination agent, whichever occurred last (an average of 6.5 months up until a max of 9.5 months) An SAE is any AE occurring at any dose that:
* Results in death;
* Is life-threatening (i.e., in the opinion of the Investigator, the participant is at immediate risk of death from the AE);
* Requires inpatient hospitalization or prolongation of existing hospitalization (hospitalization is defined as an inpatient admission, regardless of length of stay);
* Results in persistent or significant disability/incapacity (a substantial disruption of the participant's ability to conduct normal life functions);
* Is a congenital anomaly/birth defect;
* Constitutes an important medical event.Change From Baseline in White Blood Cell and Platelet Numbers 85 days after the dose of JCAR017 for Arms A, B, D, E, and F; 57 days after the dose of JCAR017 for Arm C White blood cell, and platelet counts.

A differential blood test is a blood test that measures the percentage and number of each type of white blood cell (WBC) - neutrophils, lymphocytes, monocytes, eosinophils and basophils - as well as abnormal cell types if they are present. These results are reported as percentages and absolute values, and compared against reference ranges to determine whether the values are normal, low, or high. Baseline is defined as the last measurement on or prior to any study treatment.
Change From Baseline Erythrocyte Numbers 85 days after the dose of JCAR017 for Arms A, B, D, E, and F; 57 days after the dose of JCAR017 for Arm C Change from baseline in erythrocyte (also known as red blood cell) numbers was measured using a test called a red blood cell count. Baseline is defined as the last measurement on or prior to any study treatment.
Change From Baseline Hematocrit Ratio 85 days after the dose of JCAR017 for Arms A, B, D, E, and F; 57 days after the dose of JCAR017 for Arm C The change in the proportion of red blood cells in the blood was measured using a hematocrit test. A hematocrit test measures the volume of packed red blood cells relative to whole blood. This is represented as a ratio. Baseline is defined as the last measurement on or prior to any study treatment.
Change From Baseline in Hemoglobin Levels 85 days after the dose of JCAR017 for Arms A, B, D, E, and F; 57 days after the dose of JCAR017 for Arm C The change from baseline in hemoglobin levels was measured using a hemoglobin test. A hemoglobin test measures the levels of hemoglobin in the blood. Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the rest of the body. Baseline is defined as the last measurement on or prior to any study treatment.
Change From Baseline in Specific Liver Serum Enzyme Levels 85 days after the dose of JCAR017 for Arms A, B, D, E, and F; 57 days after the dose of JCAR017 for Arm C Change from baseline in alanine aminotransferase (ALT) alkaline phosphatase (ALP), and aspartate aminotransferase (AST). Baseline is defined as the last measurement on or prior to any study treatment.
Change From Baseline in Specific Serum Protein Levels 85 days after the dose of JCAR017 for Arms A, B, D, E, and F; 57 days after the dose of JCAR017 for Arm C Change from baseline in serum albumin and protein levels. Serum protein level tests are blood tests that measure the number of proteins in the blood. Baseline is defined as the last measurement on or prior to any study treatment.
Change From Baseline in Serum Beta-2-Microglobulin Levels 85 days after the dose of JCAR017 for Arms A, B, D, E, and F; 57 days after the dose of JCAR017 for Arm C Change from baseline in serum Beta-2-Microglobulin levels was measured using a beta-2 microglobulin (B2M) tumor marker test. Baseline is defined as the last measurement on or prior to any study treatment.
Change From Baseline in Serum Bicarbonate Levels 85 days after the dose of JCAR017 for Arms A, B, D, E, and F; 57 days after the dose of JCAR017 for Arm C Change from baseline in serum bicarbonate levels was measured using a serum bicarbonate test. Baseline is defined as the last measurement on or prior to any study treatment.
Change From Baseline in Coagulation Times 57 days after the dose of JCAR017 Change from baseline in activated partial thromboplastin and prothrombin times. Activated partial thromboplastin time and prothrombin time are blood tests that measure how long it takes for blood to form a clot. Baseline is defined as the last measurement on or prior to any study treatment.
Change From Baseline in D-Dimer Levels 57 days after the dose of JCAR017 D-dimer is a substance that is produced in the body when blood clots are broken down. The D-dimer laboratory test measures the level of D-dimer in the blood and is often used to help diagnose or rule out conditions related to blood clotting, such as deep vein thrombosis (DVT) or pulmonary embolism (PE). Elevated levels of D-dimer may indicate the presence of a blood clot, but other factors can also cause an increase in D-dimer levels. Therefore, the D-dimer test is typically used in combination with other diagnostic tests to help make an accurate diagnosis. Baseline is defined as the last measurement on or prior to any study treatment.
Total Exposure to JCAR017 as Measured by the Area Under the Curve (AUC) by qPCR Up to 24 months post- JCAR017 infusion Area Under the Curve" (AUC) represents the total exposure of participants to study drug. qPCR was used to determine AUC by detecting the JCAR017 transgene.
