- The WAREHOUSE concept is based on RNA drug products shelved in a warehouse and targeting shared tumour-associated antigens (TAAs). The BioNTech Group (henceforward the "company") has identified a set of target antigens commonly expressed in TNBC. The selected breast cancer-associated antigens have been shown by immunogenicity testing to constitute suitable targets for immunotherapy and form the basis for the development of a novel RNA-based immunotherapy approach.
- The IVAC® MUTANOME concept is based on the identification of tumour-specific mutations by next-generation sequencing (NGS) and on-demand RNA manufacturing for use in single patients to target multiple neo-antigens derived from mutated epitopes. The novel therapeutic concept is supported by a series of research projects and high level publications that have led to a broad acceptance that mutation-specific T cells bear enormous potential to confer anti-tumoural activity in cancer patients.
- The TNBC-MERIT study will introduce the novel therapeutic concept for the individualized treatment of breast cancer that is based on (i) treatment with a patient-specific liposome complexed RNA tailored to the antigen-expression profile of any given patient's tumour (WAREHOUSE immunotherapy - IVAC_W_bre1_uID) and (ii) on treatment with de novo synthesized RNAs targeting up to 20 individual tumour mutations (IVAC® MUTANOME immunotherapy - IVAC_M_uID) following optional treatment with WAREHOUSE. The scientific rationale for the combination of the two IVAC® approaches is based on the assumption that immunotherapies that (1) acknowledge tumour heterogeneity on a single-patient level and (2) target the whole range of antigens selectively expressed on tumours ("cancer antigenome"), including immunogenic shared and unique antigens, bear the highest potential to constitute an effective treatment of tumours.

Experimental: ARM1 IVAC_W_bre1_uID
Patients enrolled in ARM1 will receive a treatment with four RNAs. This includes two to three variant RNAs selected from the WAREHOUSE plus p53 RNA. The selection process of RNAs from the warehouse is based on RT-PCR-based profiling of RNA extracted from patient tumour sample specimens, pre-defined cut-offs and algorithms to select the three relevant RNAs for a given patient.
Experimental: ARM2 IVAC_W_bre1_uID/IVAC_M_uID
Patients enrolled in ARM2 will optionally receive the WAREHOUSE treatment as described above followed by the personalized IVAC® MUTANOME immunotherapy. The mutation selection process constitutes a multi-step process including identification of somatic mutations by NGS, mutation confirmation and prioritization, selection, and on demand manufacturing.
Experimental: ARM3 IVAC_W_bre1_uID + RBLTet.1
Patients enrolled in ARM3 will receive a treatment with four RNAs. This includes two to three variant RNAs selected from the WAREHOUSE plus p53 RNA. The selection process of RNAs from the warehouse is based on RT-PCR-based profiling of RNA extracted from patient tumour sample specimens, pre-defined cut-offs and algorithms to select the three relevant RNAs for a given patient. RBLTet.1 RNA will be added to each RNA applied.
