$32.0 million in cash, cash equivalents and short-term investments as of December 31, 2021, is expected to provide ample runway to fund operations into 2023, including Phase 1 clinical development of its lead products GTB-3650 and GTB-5550.
BRISBANE, Calif., March 28, 2022 /PRNewswire/ -- GT Biopharma, Inc. (the "Company") (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® platform, today announced fourth quarter and full-year 2021 results for the period ended December 31, 2021.
"We're excited for GTB-3650's prospects in the new year as we advance the Company's second-generation Tri-specific NK cell engager (TriKE®) technology into an IND-enabling study. The development of GTB-3650, our lead-asset second generation nanobody TriKE® has been significantly de-risked, propelled by GTB-3550 predecessor data published in 2021 including: positive first-in-human Phase 1 data; and in-vivo animal model data, conducted in combination with a bispecific killer cell engager asset," said Michael Breen, Executive Chairman and Interim Chief Executive Officer. "Our optimism continues to rise as these proof-of-concept data demonstrate a well-tolerated safety profile and strong NK cell activation against a broad range of tumors. In total, the Company's TriKE® nanobody platform, a rich platform technology, has demonstrated broad utility. We are confident in our ability to develop these assets as a monotherapy, as a combination therapy with conventional chemotherapy, or in combination with other potential joint commercialization technologies."
The Company presented pre-clinical TriKE® data in an oral poster-presentation both virtually and in-person at ESMO Targeted Anticancer Therapies (TAT) Congress, March 7–8, 2022.
Dr. Jeffrey Miller, GT Biopharma consultant Chief Scientific Officer, also participated in an oral poster-presentation session at the European Society for Medical Oncology Immuno-Oncology (ESMO IO) Congress, December 8–11, 2021.

Fourth Quarter and Year End 2021 Financial Summary
Cash Position: The Company had total cash, cash equivalents and short-term investments of $32.0 million as of December 31, 2021, compared to $5.3 million as of December 30, 2020. This is expected to provide ample runway to fund operations into 2023 including Phase 1 clinical development of its lead products GTB-3650 and GTB-5550.
Research and Development (R&D) Expenses: R&D expenses for the fourth quarter of 2021 were $6.3 million compared to $233,000 in the same quarter a year ago. R&D expenses for the year-ending December 31, 2021, were $9.6 million compared to $485,000 in the year ended December 31, 2020. Research and development expenses increased primarily due to the admittance of additional patients into the Phase 1 GTB-3550 clinical trial and the continued development and production of our most advanced TriKE® product candidates GTB-3650 and GTB-5550.
General and Administrative (G&A) Expenses: G&A expenses for the fourth quarter of 2021 were $11.8 million compared to $2.0 million in the same quarter a year-ago. G&A expenses for the year ending December 31, 2021, were $47.9 million compared to $6.3 million for the year ending December 31, 2020. The increase in general and administrative expenses was primarily attributable to the increase in stock-based compensation and expenses incurred in support of our planned growth and new public company compliance initiatives. For the year ended December 31, 2021, we incurred $33.9 million of stock-based compensation expense as compared to $269,000 in stock-based compensation expense for the year ended December 31, 2020.

About Camelid Antibodies
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.
