GT Biopharma's Advancements in Phase 1 Trial Enrollment

GT Biopharma, Inc. (NASDAQ: GTBP), a forward-thinking immuno-oncology company, has made significant strides in the enrollment process for its Phase 1 trial featuring GTB-3650. The company focuses on creating innovative therapies leveraging its unique TriKE™ NK cell engager platform. This platform is designed to amplify the natural killer (NK) cell responses within a patient’s immune system for combatting cancer.

Current Status of Patient Enrollment

As the trial progresses smoothly, both participants in Cohort 3 have commenced treatment. Encouragingly, they have exhibited no signs of dose-limiting toxicities or concerns regarding tolerability thus far. The initial participant in this cohort has demonstrated promising indicators of immune activation, reflecting a level of activity akin to that seen in patients from the previous two cohorts.

Looking Ahead: Upcoming Cohorts and Expectations

Upon the successful assessment of safety in Cohort 3, the trial is set to escalate its dosing into Cohort 4 by the end of 2025. Notably, there is flexibility for further cohorts, with the potential to explore up to seven if needed. This flexibility augurs well for maximizing therapeutic benefits, with additional insights expected in the first quarter of 2026.

Dosing Protocol and Patient Monitoring

The design of the Phase 1 trial accommodates the evaluation of about 14 patients, with two patients allocated to each cohort. Doses are being methodically increased, starting from 1.25ug/kg/day in Cohort 1 up to 100ug/kg/day in Cohort 7. Patients will undergo treatment in two-week intervals, allowing for continuous assessment of clinical benefits over a period of up to four months. The trial aims to meticulously evaluate safety, pharmacokinetics, pharmacodynamics, in vivo expansion of endogenous NK cells, alongside clinical efficacy.

Understanding the TriKE™ Technology

GT Biopharma's TriKE™ platform represents a significant leap in cancer treatment methodologies. By enhancing how NK cells operate against tumor cells, this technology has the potential to revolutionize therapeutic approaches for hematologic malignancies. The company’s exclusive licensing agreement with the University of Minnesota empowers its research and development efforts, focused on creating therapies that could fundamentally reshape patient outcomes in oncology.

Research and Development Commitment

GT Biopharma continues to demonstrate its devotion to innovative research. The ongoing trials are complemented by an extensive evaluation of results, which aim to inform future therapeutic strategies. With the Phase 1 trial’s positive trajectory, there is heightened anticipation within the scientific community regarding potential breakthroughs in cancer immunotherapy.
