NEW YORK,June 30, 2026/PRNewswire/ -- Drug discovery has long been a slow, expensive process of trial and error, and for a small clinical-stage company, every wasted experiment is capital it can scarcely afford. That is the backdrop for a recent update fromGT Biopharma, Inc.(NASDAQ:GTBP), a clinical-stage immuno-oncology company built around its proprietary natural killer (NK) cell engager platform. On June 1, 2026, the company said it has implemented artificial-intelligence-based tools across its discovery and protein-engineering work, and that the resulting efficiency gains are expected to push multiple new development candidates into pre-IND development in 2027.

• GT Biopharma (NASDAQ:GTBP)reported increased integration ofAI-based toolsacross the discovery and engineering of its tumor-targeting NK cell engagers and multi-domain proteins, aiming to accelerate development while reducing cost.

• The company says the approachreduces reliance on trial-and-error experimentation, shortens timelines, and increases the likelihood that candidates show robust binding and functional activity before advancing.

• GT Biopharma anticipatesmultiple new development candidates entering pre-IND development in 2027, with potential targets and indications expanding beyond oncology.

• The update arrives as its clinical programs advance:GTB-3650(Phase 1, CD33-expressing blood cancers) andGTB-5550(Phase 1, B7-H3-expressing solid tumors), with the first GTB-5550 patient dosed in May 2026.

• Other publicly traded names across NK-cell, immune-engager, and AI-discovery approaches include Nkarta (NASDAQ:NKTX), Fate Therapeutics (NASDAQ:FATE), Compass Therapeutics (NASDAQ:CMPX), and Recursion (NASDAQ:RXRX), each distinct, and none a proxy for GT Biopharma.

The core of the announcement is that GT Biopharma is using AI not as a marketing veneer but at the bench, in the actual design of its molecules. According to the company, AI-guided sequence and structural analyses are used to identify new candidate tumor-targeting engagers and multi-domain proteins with favorable binding, stability, and developability profiles, allowing the team to prioritize early on the molecules most likely to succeed beyond the discovery stage. In a field where the overwhelming majority of early candidates fail, screening computationally before committing lab resources is where time and money are saved.

The company describes the tools doing more than just screening. They are also used to inform rational engineering, optimizing the orientation of protein domains, the design of the linkers that connect them, and the overall spatial architecture of a molecule, with the goals of enhancing binding, supporting productive immune-synapse formation, and minimizing structural liabilities that can hurt potency, manufacturability, or consistency. In downstream work, AI-based structural modeling is applied to predict surface exposure, steric compatibility, and assay performance, helping refine constructs before resource-intensive laboratory and animal studies. The throughline is the same: do more of the hard thinking in silico, so that the expensive, slow physical experiments are reserved for the most promising designs.

To understand why this matters for GT Biopharma specifically, it helps to know what the company makes. GT Biopharma is a clinical-stage biopharmaceutical company focused on the development and commercialization of immuno-oncology therapeutic products based on its proprietary TriKE® NK cell engager platform. As the company describes it, the TriKE® platform is designed to harness and enhance the cancer-killing abilities of a patient's immune system's natural killer cells. GT Biopharma has an exclusive worldwide license agreement with the University of Minnesota to further develop and commercialize therapies using TriKE® technology.

Designing these multi-domain proteins is exactly the kind of complex, multi-variable engineering problem where computational tools can have an outsized effect. Each TriKE has to bind the right targets with the right strength, fold and remain stable, manufacture consistently, and form a functional connection between immune cell and tumor. Optimizing all of those properties at once, by hand and by trial and error, is painstaking. That is the work GT Biopharma now says it is accelerating with AI.

The discovery update does not exist in isolation. It comes as GT Biopharma advances two TriKE candidates through Phase 1 clinical trials. GTB-3650 is being evaluated in patients with relapsed or refractory CD33-expressing hematologic malignancies, including refractory acute myeloid leukemia and high-risk myelodysplastic syndrome. GTB-5550, which targets the protein B7-H3 on solid tumors, received FDA clearance of its investigational new drug application earlier in 2026, and the company announced that its first patient was dosed in the Phase 1 dose-escalation basket trial in May 2026. Executive Chairman and CEO Michael Breen tied the two threads together, stating that as the company continues "to demonstrate clinical execution acumen with GTB-3650 and GTB-5550 advancing through Phase 1 this year, we are now looking forward to our next-generation assets with potential for shorter development timeliness, increased probability of clinical success, and lower development costs in the coming years."

Breen also characterized the shift in plain terms, saying the company has "seen a marked acceleration in our discovery productivity following recent initiatives implementing AI-based technologies, which have been adapted to improve our drug engineering capabilities." In other words, the message to investors is that the same company executing in the clinic today is simultaneously trying to build a deeper, cheaper, faster-moving pipeline behind those lead programs.

None of this removes the substantial risks that come with a micro-cap, clinical-stage biotech, and GT Biopharma is candid about them in its own disclosures. Pre-IND candidates targeted for 2027 are early, and AI-assisted design does not guarantee a molecule will prove safe or effective in humans. The company's forward-looking statements explicitly flag its ability to continue as a going concern, its need for additional capital, the possibility of clinical-trial delays, the risk that products fail to meet safety or efficacy endpoints, and the risk that its common stock could be delisted if it cannot maintain listing requirements. As of its first-quarter 2026 report, the company described a cash position in the single-digit millions, sufficient by its own account to fund operations into the latter part of the year. That financing reality is the central caveat for any investor, and it is characteristic of the high-risk, binary nature of early-stage drug development, where most candidates that enter trials never reach approval.

GT Biopharma sits within a broader field of companies pursuing NK-cell, immune-engager, and AI-driven approaches to drug development. These names are referenced for context only; each pursues a different strategy, sits at a different stage, several are far larger and better capitalized, and none is a proxy for GT Biopharma or implies any partnership or comparable outcome.Nkarta (NASDAQ:NKTX)is a dedicated NK-cell therapy developer that has increasingly oriented its engineered NK candidates toward autoimmune disease as well as cancer, underscoring the same "beyond oncology" potential GT Biopharma references.Fate Therapeutics (NASDAQ:FATE)is among the more established NK and induced-pluripotent-stem-cell platform companies, representing the better-resourced end of the cell-therapy spectrum.

Compass Therapeutics (NASDAQ:CMPX)offers a window into the broader bispecific and immune-engager landscape, developing antibody-based therapeutics that direct immune activity against tumors; while its modalities differ from TriKE, it belongs to the same conceptual family of engager formats and recently reported a stronger balance sheet and late-stage data progress.Recursion (NASDAQ:RXRX)approaches the theme from the AI angle that GT Biopharma's update highlights, pairing large proprietary datasets and machine learning with drug discovery and major pharmaceutical partnerships, while remaining clinical-stage and pre-profit. Together these names illustrate two powerful currents, NK-directed immunotherapy and AI-enabled drug design, converging on the same goal of better, faster, cheaper medicines, even as each company's fate rests on its own science and execution.

GT Biopharma's AI update is not a clinical result, and it should not be mistaken for one. What it represents is a strategic bet that the company can use modern computational tools to build its next wave of candidates faster and at lower cost, behind two clinical programs already moving through Phase 1. For a capital-constrained micro-cap, efficiency in discovery is not a luxury but a survival strategy, and the promise of pre-IND candidates in 2027 gives investors a concrete future marker to track. Whether the AI-driven approach translates into better molecules and, ultimately, successful therapies remains to be proven in the lab and the clinic. For now, the markers worth watching are the continued progress of GTB-3650 and GTB-5550 through Phase 1, the company's financing path, and the first evidence that its AI-designed candidates can advance as promised. More detail is available in the company'sJune 1, 2026 announcement.
