- Designation prioritizes investigational CTL019 (tisagenlecleucel) as a potential treatment for adult patients with relapsed/refractory (r/r) diffuse large B-cell lymphoma (DLBCL)
- R/r DLBCL, an aggressive cancer with limited options, is the second indication for CTL019 to receive Breakthrough Therapy designation
- Advances in CTL019 result from collaboration with the University of Pennsylvania; regulatory submissions for r/r DLBCL are expected to be filed by the end of the year
BASEL, Switzerland I April 18, 2017 I Novartis announced today that the US Food and Drug Administration (FDA) has granted Breakthrough Therapy designation to CTL019, an investigational chimeric antigen receptor T cell (CAR-T) therapy, for the treatment of adult patients with relapsed and refractory (r/r) diffuse large B-cell lymphoma (DLBCL), who have failed two or more prior therapies. This is the second indication for which CTL019 has received this designation; the first being for the treatment of r/r B-cell acute lymphoblastic leukemia (ALL) in pediatric and young adult patients.
"At Novartis, we are eager to unlock the full potential of CTL019, including the potential to help patients with r/r DLBCL," said Vas Narasimhan, Global Head of Drug Development and Chief Medical Officer, Novartis. "We look forward to working closely with the FDA to help bring this potential new treatment option to patients as soon as possible."
CAR-T cell therapy is different from typical small molecule or biologic therapies currently on the market because it is manufactured for each individual patient. During the treatment process, T cells are drawn from a patient's blood and reprogrammed in the laboratory to create T cells that are genetically coded to hunt the patient's cancer cells and other B-cells expressing a particular antigen.
CTL019 was first developed by the University of Pennsylvania (Penn). In 2012, Novartis and Penn entered into a global collaboration to further research, develop and then commercialize CAR-T cell therapies, including CTL019, for the investigational treatment of cancers. Through the collaboration, Novartis holds the worldwide rights to CARs developed with Penn for all cancer indications. In March 2017, Novartis announced that the FDA accepted the company's Biologics License Application filing and granted priority review for CTL019 in the treatment of r/r pediatric and young adult patients with B-cell ALL.
The Breakthrough Therapy designation is based on data from the multi-center Phase II JULIET study (NCT02445248), which is evaluating the efficacy and safety of CTL019 in adult patients with r/r DLBCL. JULIET is the second global CAR-T trial, following the Novartis ELIANA study (NCT02435849) investigating CTL019 in r/r B-cell ALL. Findings from JULIET are expected to be presented at an upcoming medical congress.
"We are encouraged by the FDA's recognition in the potential of CTL019 for this indication, which follows our promising studies of this therapy for ALL and the FDA filing by Novartis in pediatric and young adult ALL that received priority review," said the Penn team's leader, Carl June, MD, director of the Center for Cellular Immunotherapies in the Perelman School of Medicine at the University of Pennsylvania. "Work with our collaborators at trial sites across the world is paving a path to bring personalized cell therapies to more patients with these devastating blood cancers."
According to FDA guidelines, treatments that receive Breakthrough Therapy designation are those that treat a serious or life threatening disease or condition and demonstrate a substantial improvement over existing therapies on one or more clinically significant endpoints based on preliminary clinical evidence. The designation also indicates that the agency will expedite the development and review of CTL019 in adults with r/r DLBCL. This marks the 14th Breakthrough Therapy designation for Novartis since the FDA initiated the program in 2013, underscoring an emphasis to develop innovative treatments in disease areas with significant unmet need.
DLBCL is the most common form of lymphoma and accounts for approximately 30 percent of all non-Hodgkin lymphoma cases. Ten to 15 percent of DLBCL patients fail to respond to initial therapy or relapse within three months of treatment, and an additional 20 to 25 percent relapse after initial response to therapy.
Because CTL019 is an investigational therapy, the safety and efficacy profile has not yet been established. Access to investigational therapies is available only through carefully controlled and monitored clinical trials. These trials are designed to better understand the potential benefits and risks of the therapy. Because of the uncertainty of clinical trials, there is no guarantee that CTL019 will ever be commercially available anywhere in the world.
