TriKE® Technology and Pipeline - GT Biopharma's TriKE® platform utilizes camelid nanobodies to target NK cells to tumor cells, activating them via CD16A and IL-15 [5, 13] - The company has 6+ pipeline assets in preclinical development, targeting both solid tumors and hematological malignancies [5] - GTB-3650, a 2nd generation TriKE® targeting CD33, has an IND accepted in June 2024, with the first patient dosed on January 21, 2025 [5, 7] - GTB-7550 TriKE® is in development for the treatment of lupus and other autoimmune disorders [5, 37] - GTB-3550, the first generation TriKE® targeting CD33, showed proof of concept in Phase 1 in AML patients, reducing CD33+ bone marrow blast levels by 333%-636% in some patients [5, 26] Financial Status - As of March 31, 2025, GT Biopharma had $25 million in cash and short-term investments, with a debt-free balance sheet [5] - An additional $54 million in cash was raised on May 12, 2025 [5]

Akari Therapeutics Overview - Akari Therapeutics focuses on innovating antibody-drug conjugates (ADCs) as immuno-oncology therapies [3] - The company's lead payload, PH1, is a spliceosome inhibitor that causes cell death and activates the immune system [10] - Akari is developing novel target ADCs with the PH1 payload applicable to colon, lung, breast, and prostate cancers [12] PH1 Payload Mechanism and Advantages - PH1's mechanism of action generates mis-spliced transcripts leading to immunogenic neoantigens, 9 times greater than DM4 [23, 25] - PH1 overcomes resistance mechanisms and has reduced off-target toxicity due to its linker being engineered for intracellular release [17] - Preclinical data shows synergy between PH1 payload ADCs and checkpoint inhibitors [16] ADC Pipeline and Development - Akari's proprietary PH1 payload can build an entire ADC pipeline, with the ability to design several uniquely targeted ADCs in parallel [33] - AKTX-101 (Trop2 target) is ready for GMP manufacturing/GLP tox studies [36] - AKTX-102 is being developed against a novel target with potential in lung, colon, and breast cancers [36] Market Opportunity and Deal Flow - There is a strong need for ADCs with new payload mechanisms beyond current ADC therapies, especially in lung cancer [13] - Early-stage ADC deal flow shows continued momentum, with deals ranging from $20 million to $400 million upfront and total deal highlights reaching up to $1.34 billion [8] - One licensing deal for EO-1022 (HER3) reached $368 million in upfront and clinical, regulatory, and commercial milestone payments [8]
