DNA is the language of biology, and the starting material for a huge range of bioproducts. Creation of long DNA molecules is complex. Assembly PCR builds complete molecules from carefully designed fragments. However, failure is common and costly. Our AI optimization algorithms improve the success rate of this process by 36 absolute percentage points over the industry standard. Our innovation has been embedded into a software platform that unlocks BioNTech’s capacity for large scale experiments, reducing failure rates by ~5x and increasing successful design throughput by 68 percentage points over the same hardware.

Leveraging Next-Generation ADCs and IO agents for Transformative Combinations 50 Coleman N.et al. npj Precis. Onc. 2023 Next-Gen ADCs: Targeted cytotoxic agents with untapped potential 1. ADC binds to antigen 2. Internalization of the ADC complex by endocytosis 3. Payload released after linker cleavage Target antigen ADC 4. Cytotoxic effect by payload in the nucleus Bystander cell Targeted Cytotoxicity Bystander killing effect A. Release of drug payload after antigen binding before internalization B. Release of drug payload into the intercellular space due to high drug membrane permeability ADC Next-gen ADCs and IO combos represent a paradigm shift from current chemotherapy and checkpoint inhibitor treatment regimen, which could contribute to curative approaches Next-Gen IO agents: Converging multiple proven MoAs into one molecule BNT311 PM8002 MoA = Mechanism of Action; ADC = antibody-drug conjugate; IO = immuno-oncology; irAE = immune-related adverse event; CTLA-4 = cytotoxic T-lymphocyte-associated Protein 4; PD-L1 = programmed cell death ligand 1 BNT316

Our Pipeline Holds Potential for Synergistic Drug Combinations IO = immuno-oncology; ADC = antibody-drug conjugates; MoA = Mechanism of Action. ADCs quickly debulk tumors while cancer vaccines meaningfully boost the immune system to eradicate multi-clonal micrometastases hence lifting the long-term survival curve 52 Immunomodulators activate the immune system supporting vaccine-induced tumor- specific T cell responses Complementary and/or potentially synergistic MoA of immunomodulators enhance T cell priming and sustain activation +IO ADC +IO IO +ADC Cancer vaccine +IO Cancer vaccine ADCs deliver cytotoxic drugs directly to cancer cells while immunomodulators activate the immune system to recognize and destroy cancer cells Converging checkpoint inhibition and improved immune cell trafficking and ADC penetration

Most frequent TEAEs were laboratory findings (43.2%) including decreased blood cell counts, elevated liver function tests as well as levels of bilirubin and ferritin. Accordingly, cytopenia (25%) together with immune system (7%) and hepatobi liary disorders (5%) were reported frequently. 6 Most frequent non- related TESAEs were infections. 7 DLTs include 2 cases of pancytopenia, 1 case of hemophagocytic lymphohistiocytosis and 1 case of liver toxicity together with sepsis. 8 CRS was limited to G1-2 for 21/23 patients with 1 G3 and 1 G4 event. 9 Neurotoxicity was mild and self-limiting in 2 patients. 10 Most patient deaths (11/12) were related to disease progression and 1 patient died from sepsis.
