Tisagenlecleucel (Kymriah)
The chimeric antigen receptor (CAR) T-cell therapy tisagenlecleucel (Kymriah, formerly CTL019) is getting fast-tracked in the United States (US) and European Union (EU).
The US Food and Drug Administration (FDA) has accepted for priority review the supplemental biologics license application (sBLA) for tisagenlecleucel for the treatment of adults with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) who are ineligible for, or relapse after, autologous hematopoietic stem cell transplant (auto-HSCT).
Meanwhile, the European Medicines Agency (EMA) has granted accelerated assessment to the marketing authorization application (MAA) for tisagenlecleucel for the treatment of children and young adults with R/R B-cell acute lymphoblastic leukemia (ALL) and for adults with R/R DLBCL who are ineligible for auto-HSCT.
If the sBLA and MAA are approved, tisagenlecleucel will be the first CAR T-cell therapy available for 2 distinct indications in non-Hodgkin lymphoma and B-cell ALL.
Tisagenlecleucel became the first CAR T-cell therapy to receive regulatory approval when it was approved by the FDA in August 2017 for use in patients up to 25 years of age who have B-cell precursor ALL that is refractory or in second or later relapse.
Supporting data
The regulatory applications for tisagenlecleucel in the US and EU are supported by data from the Novartis-sponsored global clinical trial program in children and young adults with R/R B-cell ALL and adults with R/R DLBCL.
Results from the phase 2 JULIET trial served as the basis of the sBLA and MAA for tisagenlecleucel in adults with R/R DLCBL. Data from this trial were presented at the 2017 ASH Annual Meeting in December.
Results from the phase 2 ELIANA study were submitted as part of the MAA for tisagenlecleucel in children and young adults with R/R B-cell ALL. Data from this trial were presented at the 2017 EHA Congress last June.
About priority review, accelerated assessment
The FDA grants priority review to applications for products that may provide significant improvements in the treatment, diagnosis, or prevention of serious conditions.
The FDA’s goal is to take action on a priority review application within 6 months of receiving it, rather than the standard 10 months.
The EMA grants accelerated assessment when a product is expected to be of major public health interest, particularly from the point of view of therapeutic innovation.
Accelerated assessment shortens the review period from 210 days to 150 days.
