Over half of SMARCA4 mutations are Class I loss of function / deleterious mutations (>5% of NSCLC) SMARCA4 mutations are associated with aggressive disease and poor prognosis across a range of cancers Patients with SMARCA4 mutations are not typically eligible for other targeted therapies  Currently treated with standard of care chemotherapy or chemo-immunotherapy SMARCA4 Mutations Occur in ~10% of All NSCLC and to Varying Degrees Across Other Cancers Pancreatic: 3% NSCLC: 10% Esophageal: 8% Gastric: 8% Endometrial: 13% SCLC: 8% Urinary: 9% Colorectal: 6% 1,Dagogo-Jack et al. Journal of Thoracic Oncology. 2020 Foundation Medicine dataset 2 Fernando et al. Nature Communications 2020 SMARCA4 mutations are mostly non-overlapping with other “druggable” mutations

Outcomes for Patients with SMARCA4-mutated NSCLC are Poor with Current Standard of Care Alessi JV, et al. Clinicopathologic and genomic factors impacting efficacy of first-line chemoimmunotherapy in advanced non-small cell lung cancer (NSCLC). J Thorac Oncol. 2023 Feb 10:S1556-0864(23)00121-1. doi: 10.1016/j.jtho.2023.01.091. PMID: 36775193 (attached). Response rates are less than 25% and expected median PFS is less than 3 months in first line setting Even greater unmet need in 2nd line where fewer effective treatment options are available Patients treated with first-line chemoimmunotherapy

Selective Targeting of SMARCA2 is an Attractive Approach to Treat SMARCA4 Mutated Cancers Mutations in the chromatin remodeling complex drive cancer growth and resistance Cancer cells with SMARCA4 mutations become highly dependent on SMARCA2 for survival Selectively degrading SMARCA2 induces "synthetic lethality" in SMARCA4-deficient cancers High selectivity for SMARCA2 has been challenging because of its high similarity to SMARCA4 SMARCA: SWI/SNF-related, Matrix-associated, Actin-dependent Regulator of Chromatin, subfamily A. SMARCA2 is also known as “BRM” // SMARCA4 is also known as “BRG1”
