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 TriKE
