Forward Looking Statement Company Overview

Lead Program: CTIM-76, a Claudin 6 x CD3 Bispecific Antibody Opportunity • Claudin 6 (CLDN6) is a tumor-specific protein that is present at high surface density across many adult cancers1 • CLDN6 is expressed at very low levels or absent in normal adult tissue Challenge • CLDN6 antigen is conformationally dependent, which limits access to antibody-antigen binding and antibody development • The CLDN6 antigen binding region is highly conserved with CLDN3, CLDN4, and CLDN9, which increases the risk of off-target binding and potential side effects associated with CLDN3 (pancreas), CLDN4 (kidney, pancreas), and CLDN9 (ear, gut) Target Validation • TORL’s TORL-1-23 ADC and BioNTech’s BNT211 CAR-T cell therapy establishes Proof of Concept2,3: ‒ Efficacy: TORL-1-23 demonstrated 75% ORR (3/4 pts) at 2.4 mg/kg; BNT211 demonstrated 75% ORR (6/8 pts) at DL2 ‒ Safety: TORL-1-23 exhibited MMAE-related toxicities; BNT211 exhibited CRS that was adequately managed with anti-IL6 Company Overview Context Therapeutics Inc. - August 20233 DL2 = dose level 2; CRS = cytokine release syndrome 1 Faber MS, et al.
