BioNTech Announces Publication of Preclinical Data for First-in-Kind CAR-T Cell Therapy Approach Targeting Solid Tumors in Science
- Publication of preclinical proof-of-concept data for BNT211 reports Claudin 6 (CLDN6) as a novel target for CAR-T cell therapy of solid tumors and introduces CARVac, a first-in-kind RNA vaccine approach promoting the amplification and persistence of CAR-T cells in vivo
- Combination of CAR-T cell therapy with CARVac highlights the value of cross-platform synergies to address key development challenges in the treatment of cancer
- Applicability of CARVac to various CAR-T cell therapeutic targets offers broad potential to improve therapeutic efficacy of CAR-T cell therapies across a range of solid and liquid tumors
- First-in-human Phase 1/2 clinical trial for BNT211 in multiple solid tumors including ovarian, testicular, uterine and lung cancer intended to start in 2020
MAINZ, Germany, Jan. 02, 2020 (GLOBE NEWSWIRE) -- BioNTech SE (NASDAQ: BNTX, “BioNTech” or “the Company”), announced today a publication in Science on the company’s novel CAR-T therapeutic approach for solid tumors which utilizes a CAR-T Cell Amplifying RNA Vaccine, or CARVac. The report entitled “An RNA vaccine drives expansion and efficacy of claudin-CAR-T cells against solid tumors” provides preclinical proof-of-concept data for BioNTech’s first CAR-T product candidate BNT211, an autologous CAR-T cell therapy targeting the oncofetal antigen Claudin 6 (CLDN6), and outlines CARVac as a broadly applicable RNA vaccine approach to improve therapeutic efficacy of CAR-T cell therapies.
Although CAR-T cell therapy has shown significant clinical efficacy in blood cancers, it still faces major challenges in solid tumors, including a limited number of identified cancer-specific solid tumor targets, inefficient infiltration of CAR-T cells into solid tumors and insufficient CAR-T cell persistence. BioNTech aims to overcome these hurdles by targeting CLDN6, a novel tumor specific antigen expressed in multiple solid tumors, in combination with an RNA vaccine promoting the amplification, persistence and efficacy of CAR-T cells in vivo.
In the published study, a second generation CLDN6-CAR-T therapy with a 4-1BB costimulatory domain (BNT211) was evaluated both in vitro in tumor cell lines and in vivo in mice with human ovarian cancer transplants. In mice, CLDN6-CAR-T cell therapy demonstrated complete tumor regression of transplanted large human tumors within two weeks after treatment initiation. Furthermore, the combination with CARVac achieved an improved engraftment, proliferation and expansion of CAR-T cells in vivo resulting in tumor regression even at sub-therapeutic CAR-T doses. CARVac was also successfully applied for CAR-T cells targeting the pan-cancer antigen CLDN18.2 and CD19, the target of approved CAR-T cell therapies. The combination of CAR-T cell therapy with CARVac underlines the value of cross-platform synergies to address key development challenges in the treatment of cancer.
BioNTech intends to initiate a first-in-human Phase 1/2 clinical trial for BNT211 this year in solid tumors, including ovarian, testicular, uterine and lung cancer. Manufacturing to support clinical trials of BNT211 will be conducted in-house at BioNTech’s state-of-the-art GMP certified cell therapy manufacturing facility in Idar-Oberstein, Germany, which has been in operation since 1999. BioNTech initiated a multi-year capacity expansion at the facility in 2018 which it expects to complete in 2020.
BioNTech was founded in 2008 on the understanding that every cancer patient’s tumor is unique and therefore each patient’s treatment should be individualized. Its cutting-edge pipeline includes individualized mRNA-based product candidates, innovative chimeric antigen receptor T cells, novel checkpoint immunomodulators, targeted cancer antibodies and small molecules. BioNTech has established relationships with seven pharmaceutical collaborators, including Eli Lilly and Company, Genmab, Sanofi, Bayer Animal Health, Genentech, a member of the Roche Group, Genevant and Pfizer, and has published over 150 peer-reviewed publications on its scientific approach.
