PAGE | Competitive Difference 7 Allogeneic Gamma Delta Based T-Cell Therapies Superior specificity for multiple solid tumors Superior Efficacy from γδT cells Vertical Integration Lower Costs/ Greater Access2 Potential broad treatment for solid malignancies that express Kiromic developed biomarkers such as Iso-mesothelin. Solid tumors represent approx. 90% of new cancer diagnoses but finding specific targets to treat them has been challenging. Kiromic tackles the issue by identifying new cancer specific targets. Strong efficacy in pre-Clinical animal models. In solid tumors, the benefit of infiltrating conventional T cells may vary. In contrast, GDT cells are the infiltrating immune cells most likely to be associated with positive outcomes, as shown in an analysis of 18,000 tumors from 39 indications1 In-house cGMP manufacturing In-house QC/EM lab In-house product and process development (R&D and MSAT) 1.Outpatient treatment means reduced hospitalization and other treatment related costs. 2. Lower projected cost increases patient and health care professional access to these therapies, and potentially provides important quality-of-life benefits for patients as well. 1.
