GT Biopharma, Inc. Provides Update on Pipeline Discovery Activities from Newly Implemented AI-Based Technological Initiatives GT Biopharma, Inc. provided an update on its newly implemented AI-based technological initiatives and improved pipeline discovery efficiencies, which are expected to lead to additional development candidates advancing into pre-IND development in 2027. Increased integration of artificial intelligence–based tools across the discovery and engineering of tumor-targeting engagers and multi-domain proteins to accelerate development while reducing developmental costs. Reduces reliance on trial-and-error experimentation, shortens development timelines, and increases likelihood that pipeline candidates demonstrate robust binding and functional activity suitable for translational advancement. GT Biopharma anticipates multiple new development candidates moving into pre-IND development in 2027, with potential targets and indications expanding beyond oncology. Implementation of AI-based technology for GT Biopharma’s Discovery Pipeline: AI-guided sequence and structural analyses are used to identify de novo candidate tumor-targeting engagers and multi-domain proteins with favorable binding, stability, and developability profiles, enabling early prioritization of molecules most likely to demonstrate translation success beyond discovery. These tools further inform rational engineering by optimizing domain orientation, linker design, and spatial architecture to enhance binding, support productive immune synapse formation, and minimize structural liabilities that can impair potency, manufacturability, or consistency. In downstream applications, AI-based structural modeling is applied to predict surface exposure, steric compatibility, and assay performance, guiding construct refinement prior to resource-intensive in vitro and in vivo studies. GTB-3650 and GTB-5550 are advancing through Phase 1 this year. Announcement • May 23

Gt Biopharma Inc Announces First Patient Dosed in Phase 1 Trial of Gtb-5550, A B7-H3-Targeted Natural Killer (Nk) Cell Engager for Solid Tumors GT Biopharma, Inc. announced that the first patient was dosed in a Phase 1 dose escalation basket trial evaluating GTB-5550, its B7-H3-targeted natural killer (NK) cell engager for solid tumors expressing B7-H3. GTB-5550 is now the 3rd TriKE to enter the clinic and an expansion into a broader solid tumor opportunity, with the Phase 1 trial likely to focus on prostate cancer patients during the dose escalation phase. The company anticipates providing updates in the second half of 2026 as enrollment progresses through dose escalation cohorts. The Phase 1 trial with GTB-5550 will be the first nanobody TriKE tested with more patient-friendly subcutaneous dosing. The Phase 1a dose escalation portion of the trial will focus primarily on enrolling prostate cancer patients and evaluate up to 6 dose levels to identify the maximum tolerated dose. After the dose escalation phase, the Phase 1b expansion component will enroll patients with up to 7 different tumor types (castration-resistant prostate cancer, ovarian cancer, breast cancer, head and neck cancer, non-small cell lung cancer, pancreatic cancer, and bladder cancer) and further evaluate its safety, tolerability and preliminary anti-tumor activity. GTB-5550 will be administered by subcutaneous injection in the abdominal area for 5 consecutive days during Week 1 and Week 2 followed by 2 weeks of no treatment. One treatment cycle is 4 weeks in duration. Subsequent cycles receive treatment three times weekly for 2 weeks followed by 2 weeks of no treatment. A minimum of 2 cycles is planned, and patient-appropriate disease reassessment is performed after 2 cycles and every 8-12 weeks thereafter. Treatment may continue until disease progression, unacceptable toxicity, patient refusal, or treatment is no longer in the best interest of the patient. Patients are followed for 12 months to determine progression free survival and overall survival. More details can be found on clinicaltrials.gov with the identifier: NCT07541573. New Risk • May 14
New major risk - Share price stability The company's share price has been highly volatile over the past 3 months. It is more volatile than 90% of American stocks, typically moving 17% a week. This is considered a major risk. Share price volatility increases the risk of potential losses in the short-term as the stock tends to have larger drops in price more frequently than other stocks. It may also indicate the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$13m free cash flow). Share price has been highly volatile over the past 3 months (17% average weekly change). Shareholders have been substantially diluted in the past year (over 11x increase in shares outstanding). Revenue is less than US$1m. Market cap is less than US$10m (US$9.87m market cap). Minor Risk Currently unprofitable and not forecast to become profitable over next 3 years (US$11m net loss in 3 years). New Risk • Apr 26
New major risk - Market cap size The company's market capitalization is less than US$10m. Market cap: US$9.86m This is considered a major risk. Companies with a small market capitalization are most likely businesses that have not yet released a product to market or are simply a very small company without a wide reach. Either way, risk is elevated with these companies because there is a chance the product may not come to fruition or the company's addressable market or demand may not be as large as expected. In addition, if the company's size is the main factor, it is less likely to have many investors and analysts following it and scrutinizing its performance and outlook. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$13m free cash flow). Shareholders have been substantially diluted in the past year (over 11x increase in shares outstanding). Revenue is less than US$1m. Market cap is less than US$10m (US$9.86m market cap).

Announces FDA Clearance of Investigational New Drug for GTB-5550 TriKE, B7-H3-Targeted Natural Killer Cell Engager for Solid Tumors Expressing B7-H3 GT Biopharma, Inc. announced FDA clearance of its IND application for GTB-5550, allowing the company to proceed with a Phase 1 clinical trial, which is anticipated to initiate in mid-2026. The company expects to commence enrollment of the Phase 1 basket trial in mid-2026. While the phase I trial is open to patients with common solid tumors that express B7-H3, in the dose-escalation component will prioritize enrollment for advanced prostate, ovarian, and pancreatic cancer patients who have failed standard therapies. Based on the encouraging trends we have seen from ongoing Phase 1 trial with GTB-5550 in AML patients, the company are even more enthusiastic about the potential benefits of GTB-5550 treatment in patients with solid tumors known to express B7-H3. The Phase 1 trial with GT B-5550 will be the first dual nanobody TriKE®? tested with more patient-friendly subcutaneous dosing. The Phase 1a dose escalation portion of the trial will test up to 6 dose levels to identify the maximum tolerated dose (MTD). After the dose escalation phase, the Phase 1b expansion component of the trial will then confirm the MTD identified in the Phase 1a trial in up to 7 different possible metastatic disease cohorts (castration-resistant prostate cancer, ovarian cancer, breast cancer, head and neck cancer, non-small cell lung cancer, pancreatic cancer, and bladder cancer) and further evaluate its safety, tolerability and preliminary anti-tumor activity. GTB-5550 will be administered by subcutaneous (SQ) injection in the abdominal area for 5 consecutive days during Week 1 and Week 2 followed by 2 weeks of no treatment. Treatment may continue until disease progression, unacceptable toxicity, patient refusal, or treatment is no longer in the best interest of the patient.

GT Biopharma, Inc. Reports Continued Progress with Its Phase 1 Clinical Trial of GTB-3650 GT Biopharma, Inc. recently reported continued progress with its Phase 1 clinical trial of GTB-3650, which has now advanced into Cohort 4 at a dose level of 10µg/kg/day. The company is developing innovative immunotherapy treatments designed to combat some of the world's most challenging cancer types using its proprietary natural killer cell engager TriKE platform technology. The Phase 1 dose escalation study is evaluating GTB-3650 in patients battling relapsed or refractory blood cancers that express the CD33 protein, specifically acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS). These represent some of the most difficult cancer cases to treat, involving patients whose disease either came back after initial therapy or never responded to conventional treatment options.GTB-3650 works by stimulating the patient's natural killer cells, a type of immune cell that naturally hunts down and destroys abnormal cells, to specifically target cancer cells. Patients receive the therapy through continuous infusions following a structured schedule: two weeks of treatment followed by two weeks of rest, repeating this cycle for up to four months based on how they respond. The six patients enrolled across Cohorts 1 through 3 have all been successfully treated with GTB-3650, demonstrating the therapy's tolerability at progressively higher dose levels. According to the company, the Cohort 4 dose level of 10µg/kg/day is more reflective of the potential clinical efficacy threshold based on positive trends observed across multiple immunological biomarkers and the complete absence of dose-limiting toxicities throughout all three completed cohorts. The Phase 1 first in human trial design calls for testing GTB-3650 in approximately 14 patients across seven cohorts, with two patients per cohort receiving progressively higher doses from 1.25µg/kg/day in Cohort 1 up to 100µg/kg/day in Cohort 7 if necessary. Beyond Cohort 4, three additional higher-dose cohorts remain available: Cohort 5 at 25µg/kg/day, Cohort 6 at 50µg/kg/day, and Cohort 7 at the maximum planned dose of 100µg/kg/day. The company plans to provide the next trial update in the first quarter of 2026.Beyond blood cancers, GT Biopharma is developing GTB-5550, which targets B7H3, a protein commonly found across various solid tumor types including breast, lung, ovarian, pancreatic, bladder, and prostate cancers. The company expects to submit its regulatory application to begin human trials of GTB-5550 in late December 2025 or January 2026.Both candidates utilize GT Biopharma's proprietary TriKE platform technology, which employs specialized antibody fragments originally found in camels and llamas. These molecules offer advantages over conventional antibodies due to their smaller size and greater stability. The company holds an exclusive worldwide license from the University of Minnesota for this technology. Announcement • Oct 23
GT Biopharma, Inc. Provides Enrollment Update on GTB-3650 Phase 1 Trial in Patients with Relapsed or Refractory (r/r) CD33 Expressing Hematologic Malignancies GT Biopharma, Inc. announced successful completion of the Cohort 3 formal safety review with no safety or tolerability issues observed and advancement into Cohort 4 of its Phase 1 dose escalation trial evaluating GTB-3650 for the treatment of relapsed or refractory (r/r) CD33 Expressing hematologic malignancies. The six patients in Cohorts 1 through 3 have been successfully treated with GTB-3650 and the formal safety review of Cohort 3 showed no safety or tolerability issue observed. This has allowed progression to actively screening patients for Cohort 4. With a dose of 10 ug/kg/day, Cohort 4 is more reflective of the potential efficacy threshold. The Phase 1 trial protocol allows for three additional cohorts with much higher dose levels ranging from 25 ug/kg/day with Cohort 5, 50 ug/kg/day With Cohort 6 and 100 ug/kg/day for Cohort 7, if necessary. The company anticipates providing its next update on the trial in First Quarter 2026. The Phase 1 trial will evaluate of GTB-3650 in up to approximately 14 patients (two patients in each of seven cohorts), with doses ranging from 1.25 ug/kg/day in Cohort 1 to 100 ug/kg/day in Cohort 7. GTB-3650 is dosed in two-week blocks, two weeks on and two weeks off (defining a treatment cycle), for up to four months based on clinical benefit. The trial will assess safety, pharmacokinetics, pharmacodynamics, in vivo expansion of endogenous patient NK cells and clinical activity. Announcement • Oct 10
GT Biopharma Provides Enrollment Update on GTB-3650 Phase 1 Trial in Patients with Relapsed or Refractory (r/r) CD33 Expressing Hematologic Malignancies GT Biopharma, Inc. announced that enrollment in the dose escalation cohorts of the Phase 1 trial, evaluating GTB-3650 for the treatment of relapsed or refractory (r/r) CD33 expressing hematologic malignancies, is well on track. Enrollment in Cohorts 1 and 2 were successfully completed; both patients in Cohort 3 have now initiated treatment with no evidence of dose-limiting toxicities or safety concerns to date. The level of immune activation observed from multiple biomarkers in the first patient of Cohort 3 is consistent with the evidence of heightened immune activity in the first four patients from Cohorts 1 and 2. Assuming Cohort 3 is completed with no new safety findings, the trial will continue to dose-escalate into the higher ranges of GTB-3650 anticipated to be necessary to translate heightened immune activation into clinically meaningful evidence of therapeutic activity. Initiation of dosing in Cohort 4 is planned by year-end 2025 and additional data updates are anticipated in first quarter 2026. The Phase 1 protocol allows evaluation of GTB-3650 in up to approximately 14 patients (two patients in each of seven cohorts), with doses ranging from 1.25ug/kg/day in Cohort 1 to 100ug/kg/day in cohort 7. GTB-3650 will be dosed in two-week blocks, two weeks on and two weeks off (defining a treatment cycle), for up to four months based on clinical benefit. The trial will assess safety, pharmacokinetics, pharmacodynamics, in vivo expansion of endogenous patient NK cells and clinical activity. New Risk • Oct 08
New major risk - Share price stability The company's share price has been highly volatile over the past 3 months. It is more volatile than 90% of American stocks, typically moving 19% a week. This is considered a major risk. Share price volatility increases the risk of potential losses in the short-term as the stock tends to have larger drops in price more frequently than other stocks. It may also indicate the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$10m free cash flow). Share price has been highly volatile over the past 3 months (19% average weekly change). Shareholders have been substantially diluted in the past year (59% increase in shares outstanding).

GT Biopharma Advances into Cohort 3 of GTB-3650 Phase 1 Trial Following Safety Review of Cohort 2 GT Biopharma, Inc. announced initiation of dosing in Cohort 3 of its Phase 1 dose escalation trial evaluating GTB-3650 for the treatment of relapsed or refractory (r/r) CD33 expressing hematologic malignancies. The Phase 1 dose escalation trial is evaluating GTB-3650, GT Biopharma's second-generation TriKE, for the treatment of relapsed and refractory (r/®? CD33 expressing hematologic Malignancies. Cohorts 1 and 2 have now both been successfully completed and following the formal safety reviews, no safety or tolerability issues have been observed. This has allowed initiation of dosing in cohort 3, with the first patient now having completed the first week of cycle 1. Patients from Cohort 1 and Cohort 2 have shown encouraging early results indicative of GTB-3650's ability to activate endogenous NK cells and induce NK cell expansion. Data from multiple blood biomarker assays from the first four patients show heightened immune activity. GT Biopharma plans on releasing initial Phase 1 results later in 2025 following completion of additional dose cohorts. The trial plans to evaluate GTB-3650 in up to approximately 14 patients (seven cohorts) and GTB-3650 will be dosed in two-week blocks, two weeks on and two weeks off (defining a treatment cycle), for up to four months based on clinical benefit.

New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 46% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Negative equity (-US$980k). Shareholders have been substantially diluted in the past year (46% increase in shares outstanding). Revenue is less than US$1m. Market cap is less than US$10m (US$8.94m market cap).

New major risk - Revenue and earnings growth Earnings are forecast to decline by an average of 2.8% per year for the foreseeable future. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If profits are expected to decline, then in most cases the share price will decline over time as well. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$12m free cash flow). Earnings are forecast to decline by an average of 2.8% per year for the foreseeable future. Shareholders have been substantially diluted in the past year (62% increase in shares outstanding). Revenue is less than US$1m. Market cap is less than US$10m (US$6.26m market cap). Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$14m net loss in 3 years). Share price has been volatile over the past 3 months (11% average weekly change). Announcement • Nov 28

GT Biopharma, Inc. Announces FDA Clearance of Investigational New Drug (IND) Application for GTB-3650, an NK Cell Engager for Treatment of CD33+ Leukemia GT Biopharma, Inc. announced FDA clearance of its IND application for GTB-3650, allowing the company to proceed with a Phase 1 clinical trial, which is anticipated to start in second half of 2024. The Phase 1 dose escalation study will evaluate GTB-3650 in up to six cohorts of adult patients with relapsed or refractory (r/r) CD33 expressing hematologic malignancies, including acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS). GTB-3650 will be dosed in two-week blocks, two weeks on and two weeks off for up to four months based on clinical benefit. The trial will assess safety, pharmacokinetics, pharmacodynamics, in vivo expansion of endogenous patient NK cells and clinical activity. Camelid antibodies are single domain antibodies (sdAbs) from the Camelidae family of mammals that include llamas, camels, and alpacas. These animals produce two main types of antibodies. One type of antibody camelids produce is the conventional antibody that is made up of two heavy chains and two light chains. They also produce another type of antibody that is made up of only two heavy chains and no light chain. This is known as heavy chain IgG (hcIgG). While these antibodies do not contain the CH1 region, they retain an antigen binding domain called the VHH region. VHH antibodies, also known as single domain antibodies, contain only the VHH region from the camelid antibody. Camelid antibodies have key characteristics, which include high affinity and specificity (equivalent to conventional antibodies), high thermostability, good solubility and strictly monomeric behavior, small size, relatively low production cost, ease of genetic engineering, format flexibility or modularity, low immunogenicity, and a higher penetration rate into tissues.

New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 73% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Share price has been highly volatile over the past 3 months (46% average weekly change). Shareholders have been substantially diluted in the past year (73% increase in shares outstanding). Revenue is less than US$1m. Market cap is less than US$10m (US$7.94m market cap).

New minor risk - Share price stability The company's share price has been volatile over the past 3 months. It is more volatile than 75% of American stocks, typically moving 10% a week. This is considered a minor risk. Share price volatility indicates the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. It also increases the risk of potential losses in the short term as the stock tends to have larger drops in price more frequently than other stocks. Currently, the following risks have been identified for the company: Major Risks Earnings are forecast to decline by an average of 56% per year for the foreseeable future. Revenue is less than US$1m. Market cap is less than US$10m (US$5.21m market cap). Minor Risks Currently unprofitable and not forecast to become profitable next year (US$15m net loss next year).

GT Biopharma, Inc. Presents Positive Preclinical Data for GTB-5550, a Novel TriKE(R) Molecule for Targeted Prostate Cancer Treatment During the Society for Immunotherapy of Cancer (SITC) 2023 Annual Meeting GT Biopharma, Inc. announced positive preclinical data in highlighting GTB-5550's potential in prostate cancer. Martin Felices, PhD, Associate Professor of Medicine at the University of Minnesota, presented these data on Saturday, November 4th at the Society for Immunotherapy of Cancer (SITC) Annual Meeting 2023, which is being held in San Diego, California November. Natural killer (NK) cells are being increasingly explored in clinical trials due to their safety profile and ability to mediate tumor killing without prior priming. However, lack of antigen-specific targeting, decreased numbers, and suppressive signals from the tumor microenvironment (TME) of Prostate Cancer (PCa), can negatively impact NK cell efficacy. GTB-5550 was specifically designed as a novel tri-specific killer engager (TriKE(R)) molecule with three components: an arm that engages with CD16, an activating receptor of NK cells, an arm that binds to tumor antigens expressed in prostate cancer (PSMA or B7H3), and an interleukin (IL)-15 moiety that is essential for NK cell survival, proliferation, priming and motility. ey findings demonstrated that normal donor and prostate cancer patient NK cells displayed better, specific, degranulation against prostate cancer cell lines in the presence of PSMA or B7H3 TriKEs. NK cell cytotoxicity was also improved, even in the presence of enzalutamide resistant lines, hypoxia, or MDSCs. The TriKE molecules displayed improved tumor control, compared to IL-15 control or no treatment, in xenogeneic models of prostate cancer. Announcement • Aug 23

GT Biopharma Demonstrates Novel B7-H3 Targeting Dual Camelid Nanobody BiKE and GTB-5550 Induce NK Cell Activation Against Broad Spectrum of Tumors at ESMO IO Congress 2021 GT Biopharma, Inc. announced that the Company's mini-poster presentation abstract is now broadly available on the European Society for Medical Oncology ("ESMO") Immuno-Oncology ("IO") Congress 2021 abstracts webpage. The congress is being held from December 8-11, 2021, in Geneva Switzerland. The study was conducted by Dr. Jeff Miller's lab, University of Minnesota where functional assays were conducted with various ovarian, prostate, and hematologic malignancy cell lines with varying levels of B7H3 expression from none to very high levels. Dr. Miller's lab previously showed that dual camelid nanobody tri-specific killer engager (TriKE) (GTB-5550) specifically bound B7-H3 on PC3/C4-2 prostate cancer (PCa) cells and activated peripheral blood (PB) NK cells. The company has since developed a dual camelid bispecific killer engager (BiKE) targeting B7-H3 and show that both GTB-5550, which harbors wild-type IL-15, and BiKE display broad activity against B7-H3-expressing tumors. Compared to monomeric IL-15, GTB-5550 shows CD16-dependent metabolic activation of NK cells. Presentation highlights from the mini-poster titled, "Novel B7-H3 Targeting Dual-Nanobody NK Cell Engagers Display Robust Activity" include: Study Background: BiKE and GTB-5550 were manufactured in a mammalian expression system and purified from supernatants. Models were used to evaluate how the BiKE and GTB-5550 induce NK cell degranulation (CD107a) and interferon gamma production through a variety of cell lines including PCa cells harboring enzalutamide resistance with divergent mechanisms including 22RV1 (androgen ligand-independent AR-V7 splice variant) as well as a spontaneously resistant LNCaP model (AR hyper activation), as well as a CREB5 overexpressing (epithelial to mesenchymal transition) LNCaP model. Metabolic stimulation was measured in NK-92 cell lines. PB NK cells were robustly activated, compared to controls, when treated with GTB-5550 or BiKE and cultured with enzalutamide resistant PCa, osteosarcoma (U2OS, SaOS2), rhabdomyosarcoma (RH30), ovarian carcinoma (MA148, OVCAR8), AML (MV4;11, THP-1) and multiple myeloma (MM1S) cell lines. GTB-5550 was approximately 2 times more potent than NCI IL-15 in terms of metabolic stimulation of CD16+ NK-92 cells, but not CD16- NK-92 cells. Spheroid killing assays and deeper metabolic analyses are in progress. Results of the Study: The data demonstrated that the novel dual camelid nanobody BiKE and GTB-5550 induce NK cell activation against a broad spectrum of tumors expressing B7-H3. Furthermore, B7-H3 is expressed at high levels on prostate cancer cell lines demonstrating enzalutamide resistance, thus inducing efficient targeting of these therapy PCa refractory lines. This B7-H3 targeting NK platform demonstrates broad translational potential. GMP production of GTB-5550 has been initiated. ESMO IO 2021 presentation details: -Poster Display Title (#126P): Novel B7-H3 targeting dual nanobody NK cell engagers display robust activity against a broad spectrum of solid and hematologic malignancies GTB-5550 TriKE® product candidate is being developed for the treatment of B7H3+ solid tumor cancers. GTB-5550 is a single-chain, tri-specific scFv recombinant fusion protein conjugate composed of the variable regions of the heavy and light chains of anti-CD16 and anti-B7H3 antibodies and human IL-15. GTB-3650 is the Company's lead second-generation Tri-Specific Killer Engager TriKE® program currently in preclinical development for the treatment of relapsed/refractory acute myelogenous leukemia (AML) and high-risk myelodysplastic syndrome (MDS).

GT Biopharma Announces Updated Positive Safety Data from Phase 1 GTB-3550 Monotherapy Trike Trial an Investigational Immunotherapy for Refractory Cancers to Be Presented At ESMO Congress 2021 GT Biopharma, Inc. a clinical stage immuno-oncology company focused on developing innovative therapeutics based on the Company's proprietary natural killer cell engager, TriKE protein biologic technology platform, announced that Jeffrey Miller, MD, University of Minnesota Medical School, Professor of Medicine, Division of Hematology, Oncology and Transportation will present a mini-oral presentation at the European Society for Medical Oncology Congress 2021 to be held virtually September 16-21. The mini-oral presentation will present updated positive Phase 1 safety data, progress, and preclinical data going beyond hematologic malignancies to solid tumors of a Phase 1 GTB-3550 TriKE trial. The Tri-Specific Killer Engager TriKE program is currently in pre-clinical and clinical development for the treatment of relapsed/refractory acute myelogenous leukemia and high-risk myelodysplastic syndrome with solid tumor TriKE commercial manufacturing and IND enabling studies in progress. Therapeutic and commercial advantages of GTB-3650 compared to GTB-3550 include: Based on second generation camelid single-domain antibody technology that holds several advantages over traditional IgG monoclonal antibodies; Improved potency and enhanced binding affinity; Similar preclinical safety profile; Commercial manufacturing capabilities through arrangement with Cytovance; Proprietary patented molecule, which unlike GTB-3550, is wholly owned by GT Biopharma; Camelid antibodies are single domain antibodies from the Camelidae family of mammals that include llamas, camels, and alpacas. These animals produce 2 main types of antibodies. One type of antibody camelids produce is the conventional antibody that is made up of 2 heavy chains and 2 light chains. They also produce another type of antibody that is made up of only 2 heavy chains and no light chain. This is known as heavy chain IgG. While these antibodies do not contain the CH1 region, they retain an antigen binding domain called the VHH region. VHH antibodies, also known as single domain antibodies, contain only the VHH region from the camelid antibody. Camelid antibodies have key characteristics, which include high affinity and specificity, high thermostability, good solubility and strictly monomeric behavior, small size, relatively low production cost, ease of genetic engineering, format flexibility or modularity, low immunogenicity, and a higher penetration rate into tissues. GTB-3650 is the Company's lead second-generation Tri-Specific Killer Engager TriKE program currently in preclinical development for the treatment of relapsed/refractory acute myelogenous leukemia and high-risk myelodysplastic syndrome.

GT Biopharma, Inc. Announces Update on the Commencement of the GTB-3550 Trike Monotherapy Phase 2 Clinical Trial and Solid Tumor Trike Product Candidates GT Biopharma, Inc. provided an update concerning the commencement of the GTB-3550 TriKE monotherapy Phase 2 clinical trial, and certain of its solid tumor targeting TriKE product candidates. Highlights to date from patients treated with GTB-3550 TriKE in the dose escalation Phase 1 clinical trial for the treatment of high-risk myelodysplastic syndromes (MDS) and refractory/relapsed acute myeloid leukemia (AML): Up to 63.7% Reduction in Bone Marrow Blast Levels seen in some patients. Restoration of Patient's Endogenous NK Cell Function, Proliferation and Immune Surveillance. No Progenitor-derived or Autologous/Allogenic Cell Therapy Required. No Cytokine Release Syndrome Observed. While the design of the Phase 1 part of the GTB-3550 clinical trial was focused on evaluating safety, indications of anti-tumor activity during Phase 1 have resulted in a refocusing of the Phase 2 design of the clinical trial towards enhancing efficacy, durability of the clinical response, and overall survival with the goal to seek accelerated approval from FDA. The company intends to enroll patients with CD33 expression =50% in two independent cohorts (higher-risk myelodysplastic syndrome and acute myeloid leukemia); treat patients with two cycles of GTB-3550 therapy with a rest period between cycles as opposed to the single-cycle used during Phase 1; enroll patients with fewer prior treatment lines; and, evaluate the potential use of minimal residual disease (MRD) based endpoints that may allow for accelerated approval. Solid tumor cancers present a significantly larger market opportunity than hematologic cancer indications, and represent the majority of new cancer diagnoses annually. The Company is presently advancing three TriKE product candidates in GMP manufacturing and early clinical development. These solid tumor TriKE product candidates will target cancers expressing HER2 (GTB-6550), PD-L1 (GTB-4550) and B7H3 (GTB-5550), and will be evaluated for the treatment of multiple cancers such as breast, lung, gastric, colorectal and ovarian.

GT Biopharma, Inc. Updates Interim GTB-3550 Trike™ Clinical Trial Results GT Biopharma, Inc. announced updated interim Phase I/II clinical trial results for the Company's lead therapeutic candidate, GTB-3550, being evaluated for the treatment of high-risk myelodysplastic syndromes (MDS) and refractory/relapsed acute myeloid leukemia (AML). To date, 9 patients have been enrolled in the Phase I/II Expansion clinical trial. Patients enrolled early in the Study (patients 1-4) were treated with doses of GTB-3550 below the anticipated therapeutic dose (RP2D) and maximum tolerated dose (MTD) to address possible safety concerns. All patients treated at the lower doses exhibited no signs of toxicity, and did not experience any Grade of Cytokine Release Syndrome (CRS). Patients 5-9 were treated with increasing doses of GTB-3550 (25mcg/kg/day, 50mcg/kg/day and 100mcg/kg/day, respectively). Three of the five patients (60%) experienced reduction in bone marrow blasts with two patients (one patient treated at the 50mcg/kg/day dose level and one patient treated at the 100mcg/kg/day dose level) experiencing significant reductions in bone marrow blast levels. As previously reported, Patient 7 treated at the 50mcg/kg/day dose level achieved a 61.7% reduction in bone marrow blast levels from 12% before therapy to 4.6% after GTB-3550 therapy. Patient 9 treated at the 100mcg/kg/day dose level achieved a 63.7% reduction in bone marrow blast levels from 22% before therapy to 8% after therapy. All patients treated at these higher doses of GTB-3550 did not experience any Grade of Cytokine Release Syndrome (CRS). All patients treated to date with GTB-3550 TriKE displayed no signs of any Grade of cytokine release syndrome (CRS). Of particular note, GTB-3550 is currently being administered to patients at doses significantly higher than the reported MTD (Maximum Tolerated Dose) for continuous infusion of recombinant human IL-15 (Interleukin-15) (Waldmann, TA et al, Clin Cancer Res. (2019) 25:4945–54). GTB-3550 is a single-chain, tri-specific scFv recombinant fusion protein conjugate composed of the variable regions of the heavy and light chains of anti-CD16 and anti-CD33 antibodies, and a modified form of IL-15. Correlative studies have shown reproducible endogenous ("native") NK cell activity in all patients. NK cell activation increases early during treatment. This finding correlated with an increase proportion and absolute number of NK cells during treatment. Targeted delivery of IL-15 to NK cells via GTB-3550 TriKE showed preferential proliferation of NK cells and significantly less effect on CD8+ and CD4+ T-cells. company also observed no CD16 shedding by patients' NK cells, and saw enhanced HL-60 AML target cell killing. This data indicates GTB-3550 TriKE™ rescues the patient's exhausted/inhibited endogenous NK cells resulting in their activation, proliferation and persistence. Announcement • Mar 09
GT Biopharma, Inc. Announces Preclinical Results For Its ROR1 TriKE™ As A Treatment For Prostate Cancer GT Biopharma, Inc. announced preclinical results for its ROR1 TriKE™ product candidate as a prospective therapy for the treatment of prostate cancer. Tyrosine kinase transmembrane receptor ROR1 has recently been shown to be overexpressed on certain cancer cells, and appears to play a functional role in promoting migration/invasion and influencing the metastatic potential of various solid tumor cancers. Targeting ROR1 on cancer cells with TriKE™ and redirecting NK cells to attack and kill cancer cells expressing ROR1, could result in a therapeutic treatment that limits the metastatic potential and invasiveness of certain solid tumor cancers. The ROR1 TriKE™ was evaluated in several preclinical models of prostate cancer, and was found to be effective at promoting NK cell killing of multiple prostate cancer cells including LnCAP, C4-2, PC-3, DU-145, VCaP and 22RV1. Significant NK cell activation and interferon gamma (IFN?) production was also observed as a result of TriKE™ engagement and activation of the NK cell. Announcement • Mar 05

GT Biopharma Announces Eighth Patient Begins Treatment of GTB-3550 GT Biopharma, Inc. announced the continuation of enrollment with patient 8 in its GTB-3550 clinical trial following the conclusion of a 30-day Covid-19 related pause in enrolling patients in all clinical trials currently being conducted at the University of Minnesota'sMasonic Cancer Center. Patients with CD33+ malignancies (primary induction failure or relapsed AML with failure of one reinduction attempt or high-risk MDS progressed on two lines of therapy) age 18 and older are eligible to participate in the GTB-3550 TriKE™ clinical trial (NCT03214666). The primary endpoint of the Study is to identify the maximum tolerated dose (MTD) of GTB-3550 TriKE. Correlative objectives include the number, phenotype, activation status and function of NK cells and T cells. The GTB-3550 TriKE clinical trial commenced patient enrollment in February 2020 for the treatment of relapsed/refractory acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (HR-MDS). To date, seven patients have been enrolled in the clinical trial; two patients treated at 5 mcg/kg/day, two patients treated at 10 mcg/kg/day, two patients at 25 mcg/kg/day, and one patient treated at 50 mcg/kg/day. All seven patients have completed therapy. The results to date have been positive and the company continues to expand the enrollment. High-risk myelodysplastic syndromes (HR-MDS) patient had failed hypomethylating agent and Luspatercept therapies prior to being treated with GTB-3550 at 50mcg/kg/day (three consecutive 96-hour continuous infusions). The patient achieved bone marrow blast level reduction from 12% before GTB-3550 therapy to 4.6% post GTB-3550 therapy determined by morphological assessment (61.7% reduction in cancer cells), and had stable hematologic parameters including normal platelet counts throughout therapy. Following this single course of GTB-3550 therapy and the significant reduction in bone marrow blast levels, the patient demonstrated clinical benefit from GTB-3550 therapy, and qualified for and has received a hematopoietic stem cell transplant (HSCT). The only treatment with curative intent for a majority of elderly HR-MDS or relapsed/refractory AML patients is allogeneic hematopoietic stem cell transplant (HSCT). GTB-3550 TriKE therapy represents a novel, low intensity therapeutic option which has the potential to increase HSCT eligibility for elderly HR-MDS and relapsed/refractory AML patients. Two patients with relapsed/refractory acute myeloid leukemia who has previously failed prior therapies prior to being treated with GTB-3550; one patient treated at 5mcg/kg/day achieved stable disease and another patient treated at 25mcg/kg/day experienced a 33% reduction in bone marrow blast levels. No signs of clinical immune activation, and no dose limiting toxicity such as cytokine release syndrome (CRS) or serious adverse events (SAEs) or fevers, tachycardia or constitutional symptoms have been observed in any patient treated to date with GTB-3550 TriKE. Correlative studies also showed no shedding of CD16 from patient's NK cells, and potent NK cell activation, proliferation and target cell killing without the need for supplemental autologous NK cell therapy. Targeted delivery of IL-15 to NK cells via GTB-3550 TriKE therapy showed preferential proliferation of NK cells, significantly less effect on CD8+ T-cells, and no observed toxicity at 25x the previous reported MTD for continuous infusion of recombinant human IL-15. GTB-3550 TriKE is a single-chain, tri-specific scFv.recombinant fusion protein conjugate composed of the variable regions of the heavy and light chains of anti-CD16 and anti-CD33 antibodies.
