EAST HANOVER, N.J., Dec. 6, 2015 /PRNewswire/ -- Findings from an ongoing Phase IIa study to evaluate the safety and efficacy of investigational chimeric antigen receptor T cell (CART) therapy CTL019 in certain types of relapsed or refractory (r/r) non-Hodgkin lymphoma will be presented in an oral session at the 57th American Society of Hematology (ASH) annual meeting. The study, conducted by the University of Pennsylvania's Perelman School of Medicine (Penn), found an overall response rate (ORR) at three months of 47% (7/15) in adult patients with r/r diffuse large B-cell lymphoma (DLBCL) and an ORR of 73% (8/11) in adult patients with follicular lymphoma (FL)1. Results will be presented in an oral session at ASH on Sunday, December 6 (Abstract #183, 8 a.m.)1.
"These data add to the growing body of clinical evidence on CTL019 and illustrate its potential benefit in the treatment of relapsed and refractory non-Hodgkin lymphoma, a disease with few effective options," said lead investigator Stephen Schuster, M.D., Associate Professor, Division of Hematology/Oncology at the University of Pennsylvania, Abramson Cancer Center. "We look forward to continuing this study to further understand longer-term patient response."
The study findings include 26 adult patients (15 with DLBCL and 11 with FL) who were evaluable for response. The study found that three patients with DLBCL who achieved a partial response (PR) to treatment at three months converted to complete response (CR) by six months. In addition, three patients with FL who achieved a PR to treatment at three months converted to CR by six months. One DLBCL patient with a PR to treatment at three months experienced disease progression at six months after treatment. One FL patient with a PR to treatment at three months who remained in PR at nine months experienced disease progression at approximately 12 months after treatment. Median progression-free survival (PFS) was 11.9 months for patients with FL and 3.0 months for patients with DLBCL.
In the study, four patients developed cytokine release syndrome (CRS) of grade 3 or higher. CRS has been observed after CTL019 infusion when the engineered cells become activated and multiply in the patient's body. During CRS, patients typically experience varying degrees of flu-like symptoms with high fevers, nausea, muscle pain, and in some cases, low blood pressure and breathing difficulties. Neurologic toxicity occurred in two patients, including one grade three episode of delirium and one possibly related grade five encephalopathy1.
In contrast to typical small molecule or biologic therapies, CTL019 is specifically manufactured for each individual patient. A patient's T cells are collected through a specialized blood draw called leukapheresis and then transferred to the Novartis manufacturing facility in Morris Plains, New Jersey. There the cells are reprogrammed to hunt cancer and other B-cells expressing CD19. The patient's own modified cells are then transferred back to the treatment center where they are administered to the patient.
A poster presentation on December 6, 6-8 p.m., will report on how the successful transfer of cell processing technology from Penn to the Novartis cell manufacturing center in Morris Plains has enabled the scale-up of CTL019 production (Abstract #3100)2. The Morris Plains facility is the first FDA-approved Good Manufacturing Practices quality site for a cell therapy production in the US and is now processing cells to support ongoing Phase II multi-center global studies of CTL019 in specific leukemias and lymphomas.
"The company's investment in our state-of-the-art manufacturing facility has given us the capacity and scalability needed to support our growing global clinical trial program," said Usman Azam, MD, Global Head, Cell & Gene Therapies Unit, Novartis Pharmaceuticals. "Novartis is proud to be the first healthcare company to initiate Phase II CART therapy trials in the US, Europe, Canada and Australia. This is a significant step forward in our mission to help address unmet medical needs of patients." A list of participating trial centers is available at https://clinicaltrials.gov.
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 uncertainty of clinical trials, there is no guarantee that CTL019 will ever be commercially available anywhere in the world.
The foregoing release contains forward-looking statements that can be identified by words such as "ongoing," "investigational," "will," "potential," "growing," "look forward," "continuing," "step forward," "mission," "yet," or similar terms, or by express or implied discussions regarding potential marketing approvals for CTL019, or regarding potential future revenues from CTL019. You should not place undue reliance on these statements. Such forward-looking statements are based on the current beliefs and expectations of management regarding future events, and are subject to significant known and unknown risks and uncertainties. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those set forth in the forward-looking statements. There can be no guarantee that CTL019 will be submitted or approved for sale in any market, or at any particular time. Nor can there be any guarantee that CTL019 will be commercially successful in the future. In particular, management's expectations regarding CTL019 could be affected by, among other things, the uncertainties inherent in research and development, including unexpected clinical trial results and additional analysis of existing clinical data; unexpected regulatory actions or delays or government regulation generally; the company's ability to obtain or maintain proprietary intellectual property protection; general economic and industry conditions; global trends toward health care cost containment, including ongoing pricing pressures; unexpected safety issues; unexpected manufacturing or quality issues, and other risks and factors referred to in Novartis AG's current Form 20-F on file with the US Securities and Exchange Commission. Novartis is providing the information in this press release as of this date and does not undertake any obligation to update any forward-looking statements contained in this press release as a result of new information, future events or otherwise.
