Comparison of Point-of-care Produced CAR T-cell With Commercial CAR T-cells in Patients With R/R LBCL (HOVON161)

A Phase II Non-inferiority Study Comparing Point-of-care Produced CAR T-cell to Commercial CAR T-cells in Patients With Relapsed/Refractory Non-Hodgkin Lymphoma

A phase II, multi-center study to compare the feasibility, and clinical efficacy of local manufacturing of CD19-directed CAR T-cells (ARI-0001 CAR T-cells) with commercial produced CAR T-cells (for example axicabtagene ciloleucel, a CD19 targeting commercially available CAR T-cell) in patients with relapsed or refractory (R/R) DLBCL.

Study Overview

• Status: Recruiting
• Conditions: NHL; DLBCL - Diffuse Large B Cell Lymphoma
• Intervention / Treatment: Drug: ARI-0001; Drug: Axi-cel

Detailed Description

Chimeric antigen receptor (CAR) T-cell therapy is an innovative form of adoptive cell therapy that has proven its efficacy in the treatment of various hematological malignancies, including B-cell non-Hodgkin lymphoma (NHL) and B-cell acute lymphoblastic leukemia (ALL). CD19 has been the most studied target antigen for CAR T-cell immunotherapy. Anti-CD19 CAR T-cell therapy has shown durable responses in patients with different B-NHLs, including Diffuse Large B-cell Lymphoma (DLBCL).

Unfortunately, up to 50-60% of the patients do not respond to CD19-directed CAR T-cell therapy or relapse. There are several shortcomings of current CD19-directed CAR T-cell therapy, that are likely responsible for therapy failure, namely: i) Due to centralized production at commercial sites, the production is time consuming (about 4 weeks), meaning that patients with rapidly progressive lymphoma may not reach the moment of the infusion of the anti-CD19 CAR T-cells. ii) Furthermore, for the current production processes, the autologous T-cells need to be cryopreserved for shipment from the hospital to the production sites and vice versa. This (double) cryopreservation process can decrease the quality of the CAR T-cells. This trial aims to address these shortcomings and will study the feasibility, and clinical efficacy of local manufacturing of CD19-directed CAR T-cells (ARI-0001 CAR T-cells), in a completely closed system using the CliniMACS Prodigy device. This study will compare the clinical efficacy of locally produced CAR T-cells to commercial produced CAR T-cells (for example axicabtagene ciloleucel, a CD19 targeting commercially available CAR T-cell) in patients with relapsed or refractory (R/R) DLBCL.

This in-house (point-of-care) production process of ARI-0001 will take approximately 12 days and thus will generate CAR T-cells "faster" which will be infused in the patient without cryopreservation ("fresh"). Furthermore, the point-of-care production process can be replicated in academic institutions with the appropriate cellular manufacturing facilities. If successful, this study will show feasibility of local production of CAR T-cell therapy, improving their rapid accessibility and quality.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-free survival (PFS) from date of IMP infusion (if applicable)	PFS from date of IMP infusion is defined as the time from IMP infusion, until progression, relapse or death from any cause, whichever comes first. PFS reflects tumor growth and, therefore, occurs prior to the endpoint of OS. Progression is defined as the first date of documentation of a new lesion or enlargement of a previous lesion, or the date of the scheduled clinic visit immediately after radiologic assessment has been completed. If there is missing information, censoring of the data may be defined as the last date at which progression status was adequately assessed.	Approximately up to 60 months following first patient IMP infusion

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-free survival (PFS) from date of randomization	PFS from date of randomization is defined as the time from enrollment, until progression, relapse or death from any cause, whichever comes first. PFS reflects tumor growth and, therefore, occurs prior to the endpoint of OS. Progression is defined as the first date of documentation of a new lesion or enlargement of a previous lesion, or the date of the scheduled clinic visit immediately after radiologic assessment has been completed. If there is missing information, censoring of the data may be defined as the last date at which progression status was adequately assessed.	Approximately up to 60 months following first patient enrollment
Safety and toxicity assessment per AE reporting	Safety and toxicity assessment of ARI-0001 CAR T-cells and Axi-cel per AE reporting classified according to CTCAE Version 5 and CRS and ICANS classified according to the ASTCT criteria. The number and proportion of patients in the specific safety population with CTCAE grade 2, 3 or 4 (incl. grade 5) will be tabulated by randomization arm. Per site, the maximum observed grade per cycle within a patient will be used.	Approximately up to 60 months following first patient IMP infusion
Overall Response Rate (ORR)	ORR is the sum of complete response (CR) and partial response (PR), as well as CR, PR, SD and PD/relapse at 4 weeks, 12 weeks, 6, 12 and 24 months after infusion of CAR T-cells.	At 4 weeks, 12 weeks, 6, 12 and 24 months after infusion of CAR T-cells
Expansion of CAR T-cells	Expansion of CAR T-cells will be assessed in both treatment arms. The central lab will collect these data, but the vast majority will not be entered in the ALEA database, and will only be analyzed by the central lab. Further details and analyses will be described in a separate SAP, which will be written by those involved in that specific analysis.	Approximately up to 60 months following first patient IMP infusion
Phenotype of CAR T-cells	Phenotype of CAR T-cells will be assessed in both treatment arms. The central lab will collect these data, but the vast majority will not be entered in the ALEA database, and will only be analyzed by the central lab. Further details and analyses will be described in a separate SAP, which will be written by those involved in that specific analysis.	Approximately up to 60 months following first patient IMP infusion
Persistence of CAR T-cells	Persistence of CAR T-cells will be assessed in both treatment arms. The central lab will collect these data, but the vast majority will not be entered in the ALEA database, and will only be analyzed by the central lab. Further details and analyses will be described in a separate SAP, which will be written by those involved in that specific analysis.	Approximately up to 60 months following first patient IMP infusion
Best Overall Response (BOR)	BOR is the best response recorded from randomization until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started) or start treatment in follow up, whichever occurs first. The patient's best response assignment will depend on the achievement of both measurement and confirmation criteria. It will be analyzed at 4 weeks, 12 weeks, 6, 12 and 24 months after infusion of CAR T-cells.	4 weeks, 12 weeks, 6, 12 and 24 months after infusion of CAR T-cells
Duration Of Response (DOR)	DOR is measured from the time measurement criteria are met for CR or PR (whichever is first recorded) until time of the last assessment of response before the first date that recurrent or progressive disease is objectively documented (taking as reference for PD the smallest measurements recorded since the treatment started). New treatment in follow up or death without previous recurrent or progressive disease will be considered as competing risks.	Approximately up to 60 months following first patient IMP infusion
Overall Survival (OS)	OS is defined as the time from date of enrollment or from IMP infusion to the date of death from any cause (2 separate endpoints). Patients still alive will be censored at the date of last contact.	Approximately up to 60 months following first patient IMP infusion
