BEVERLY HILLS, Calif., April 19, 2021 /PRNewswire/ — GT Biopharma, Inc. (NASDAQ: GTBP), a clinical stage immuno-oncology company focused on developing innovative therapeutics based on the Company’s proprietary natural killer (NK) cell engager (TriKE) protein biologic technology platform, reported financial results for the fourth quarter and year ended December 31, 2020.
“2020 was a year of robust clinical progress and milestone achievements for GT Biopharma, which allowed us to accomplish a major corporate milestone in listing GT Biopharma on NASDAQ at the beginning of 2021. The emerging data from our GTB-3550 TriKE program in hematological malignancies, MDS and AML, are encouraging in both safety and efficacy profiles. The ongoing data profile has demonstrated significant differences from all other NK cell therapies and NK engager companies, making TriKE a monotherapy, off-the-shelf platform therapeutic. TriKE exerts its therapeutic effect without the need for outside assistance in the form of combination therapies or the addition of supplemental progenitor-derived or autologous/allogenic NK cells. As a result, TriKE therapy cost to patients will be far superior, significantly more economic than progenitor-derived or autologous/allogenic NK cell therapy companies’ offerings. Additionally, the results generated from the GTB-3550 TriKE clinical trial reinforces its versatility, providing a clear rationale to proceed with additional programs in solid tumor and hematologic cancers. As a result, in 2020 we formed a strong GMP manufacturing partnership with Cytovance Biologics to bring our TriKE product candidates forward for evaluation in the clinic,” said Anthony J. Cataldo, GT Biopharma’s Chairman and Chief Executive Officer. “In the first quarter of 2021, we have achieved numerous clinical and operational milestones, which included garnering the attention of institutional investors and analyst research coverage as a result of our successful NASDAQ listing and public offering. We transferred all TriKE GMP manufacturing to Cytovance, as we progress our solid tumor TriKE product candidates. Additionally, the interim results from our ongoing Phase I/II clinical trial of GTB-3550 TriKE showed a 63.7% reduction in bone marrow blast (cancer cell killing) levels in patient 9; up from 61% in patient 7 at a lower dose for patients with MDS and AML. We also added the University of Wisconsin-Madison as a second clinical trial site. There will be more trials sites added, as we will soon proceed to the Phase II portion of our ongoing GTB-3550 TriKE clinical trial. We look forward to building on this momentum throughout the year, particularly as we continue to dose escalate our GTB-3550 TriKETM in these incredibly difficult-to-treat relapsed/refractory AML and high-risk MDS patient populations. We thank the patients and their families for their contribution, as we progress this novel, off-the-shelf monotherapy cancer therapeutic that uniquely works without outside supplemental engineered NK cells or the need for any combination drugs.”
- Strengthened Leadership Team with Key Appointments to Executive Management, Board of Directors, and Scientific and Medical Advisory Board: In November 2020, GT Biopharma announced the appointment of Michael Handelman, CPA as Chief Financial Officer. Mr. Handelman was the former CFO of Iovance Biotherapeutics. Throughout 2020, GT Biopharma announced multiple appointments to its two boards. Bruce J. Wendel was named Vice Chairman and Independent Director of the Board of Directors, and Greg Berk, M.D., Michael Breen and Rajesh Shrotriya, M.D. were appointed as independent directors.

About GTB-3550 TriKE
GTB-3550 is the Company’s first TriKE product candidate being initially developed for the treatment AML. 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. The natural killer (NK) cell stimulating cytokine human IL-15 portion of the molecule provides a self-sustaining signal that activates NK cells and enhances their ability to kill. We intend to study GTB-3550 in CD33 positive leukemias such as acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and other CD33+ hematopoietic malignancies.
