Dose Escalation Study of UCART19 in Adult Patients With Relapsed / Refractory B-cell Acute Lymphoblastic Leukaemia (CALM)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The study is in two parts: a dose escalation then a safety dose expansion. The purpose of the dose escalation part is to evaluate the safety and tolerability of ascending doses of UCART19 (dose-escalation part) given as a single infusion in patients with relapsed / refractory (R/R) B-cell acute lymphoblastic leukaemia (B-ALL), to determine the maximum tolerated dose (MTD), the recommended dose and the lymphodepletion regimen. The purpose of the safety dose expansion is to assess the safety and tolerability of the RD for UCART19.
Phase I, Open Label, Dose-escalation Study Followed by a Safety Expansion Part to Evaluate the Safety, Expansion and Persistence of a Single Dose of UCART19 (Allogeneic Engineered T-cells Expressing Anti-CD19 Chimeric Antigen Receptor), Administered Intravenously in Patients With Relapsed or Refractory CD19 Positive B-cell Acute Lymphoblastic Leukaemia (B-ALL)

Dose escalation part: Dose Limiting Toxicities (DLTs) occurence. Dose expansion part: AE throughout the study. [ Time Frame: Dose Escalation: Up to day 28 post first UCART19 infusion. Dose Expansion: From inclusion to Month 12 ]
Secondary Outcome Measures :
Incidence and Severity of Adverse Events as a Measure of Safety and Tolerability [ Time Frame: From inclusion to Month 12 ]
Adverse events assessed according to NCI-CTCAE v5.0 criteria
Objective Remission Rate [ Time Frame: At Day 28, Day 84, Month 4, Month 6, Month 9 and Month12 ]
Proportion of patients in whom a response among molecular complete remission (mCR), morphologic complete remission (CR) and complete remission with incomplete blood count recovery (CRi)
Duration of remission [ Time Frame: From the time that response criteria are first met until the date of progression or death (whatever the reason of death), whichever occurs first, assessed up to Month 12 ]
Time to remission [ Time Frame: From the date of UCART19 administration until the date that response criteria are met, assessed up to Month 12 ]
Progression Free Survival (PFS) [ Time Frame: From the date of UCART19 administration until the date of progression or the date of death (whatever the reason of death), whichever occur first, assessed up to Month 12 ]
Overall Survival (OS) [ Time Frame: From the date of UCART19 administration to the date of death from any cause, assessed up to Month 12 ]

Individual Participant Data (IPD) Sharing Statement:
Plan to Share IPD:
Qualified scientific and medical researchers can request access to anonymized patient-level and study-level clinical trial data.
Access can be requested for all interventional clinical studies:
used for Marketing Authorization (MA) of medicines and new indications approved after 1 January 2014 in the European Economic Area (EEA) or the United States (US).
where Servier is the Marketing Authorization Holder (MAH). The date of the first MA of the new medicine (or the new indication) in one of the EEA Member States will be considered for this scope.
In addition, access can be requested for all interventional clinical studies in patients:
sponsored by Servier
with a first patient enrolled as of 1 January 2004 onwards
for New Chemical Entity or New Biological Entity (new pharmaceutical form excluded) for which development has been terminated before any Marketing authorization (MA) approval.
Statistical Analysis Plan (SAP)
Informed Consent Form (ICF)
Clinical Study Report (CSR)
After Marketing Authorisation in EEA or US if the study is used for the approval.
Researchers should register on Servier Data Portal and fill in the research proposal form. This form in four parts should be fully documented. The Research Proposal Form will not be reviewed until all mandatory fields are completed.
