PAGE | 10 Major Barriers Currently Restrict Mass Adoption of Traditional CAR-T Therapy for Cancer Treatment 1. Efficacy Cancer cells can begin to mutate resulting in ”antigen escape” which reduces the efficacy of CAR-T. The lack of available predictive biomarkers is also an issue which limits the development of new and effective cancer immunotherapeutics.1 3. Safety & Toxicity Current FDA approved CAR-T cell therapy products carry a high risk of side effects including the Cytokine Release Syndrome (CRS) and Immune Cell Associated Neurotoxicity Syndrome (ICANS).3 5. Manufacturing Challenges Traditional CAR-T cell manufacturing can range from 2-5 weeks. This can be an issue for late-stage cancer patients when timing is especially critical. Harvesting viable patient derived T-cells can also be a challenge for very sick patients. As traditional autologous CAR-T cell therapies are also specific to the patient, “mass” production is also not possible as each infusion is only for the patient themselves. 4. Development Lead Time Traditional development lead time for new immunotherapies usually take years, significant expert resources, and can cost over $1B in development expenditures.4 2. Cost Effectiveness Hospitals must charge $2-2.5M per treatment to avoid losing money with current autologous CAR-T cell treatments due to treatment related toxicities (the cost for Kymriah/Novartis alone is $475K per treatment with the additional costs secondary to inpatient treated toxicities).2 1Research and Markets; Immune Checkpoint Inhibitors Market.

Review of Indications of FDA Approved checkpoint inhibitors per NCCN guidelines with the level of evidence. Cancers; Mar 2020;12(3):738. PD-L1 receptor on patient’s tumor cell Kiromic’s engineered Gamma Delta T cell (chPD1) With Kiromic’s engineered Ch-Pd1 cell, after binding to tumor cell, the T-Cell natural cancer killing ability is activated, improving the ability of the T-cell to kill cancer cells 1. Kiromic ALEXISTM-PRO-1 (Procel TM) - Targeting PDL-1 Expression In Tumor Tissues ▪ Human T-cells are very effective natural cancer killers. Many cancer cells however can evade T-cell detection by developing PD-L1 receptors that “put the brakes” on the T-cell’s cancer killing abilities. That is why traditional T-Cell based therapies can be ineffective. ▪ Kiromic’s engineered Gamma Delta T-Cell (chPD1) approach seeks to introduce 2 key elements that have the potential to significantly enhance immune response. A. Blocks the ability of checkpoints like PD-L1 from inactivating a T-cell (similar to checkpoint inhibitors) B. Engineered gamma delta T-cells are now able to kill cancer cells with enhanced potency upon binding with the PD-L1 receptor. ▪ Since many solid tumors have a wide expression of PD-L11, this means that most solid cancers such as lung, melanoma, gastric, esophagus, colorectal, breast, prostate, liver, urothelial, renal, cervical, and head and neck can potentially now be effectively treated.

Tumor volumes and mice weight were measured daily for an additional 30 days. The dotted vertical line indicates the day when the gdT cells were administered.
