VANCOUVER, BC, Oct. 15, 2025 /PRNewswire/ -- USA News Group News Commentary – Biomarker-driven drug development is accelerating across oncology as companies advance novel mechanisms targeting previously difficult-to-treat patient populations. The cancer immunotherapy market reached $226 billion in 2024 and continues expanding rapidly, driven by precision approaches that pair targeted agents with immunotherapy, identify genetic vulnerabilities, and deploy radioligand therapies for metastatic disease[1]. Recent clinical data demonstrating high response rates in biomarker-selected populations underscore the shift toward molecularly defined patient subgroups, while FDA priority reviews and breakthrough designations are compressing development timelines for innovative platforms. This convergence of scientific innovation and regulatory momentum positions companies advancing differentiated mechanisms across multiple tumor types for significant value creation, including GT Biopharma, Inc. (NASDAQ:GTBP), IDEAYA Biosciences, Inc. (NASDAQ:IDYA), Zymeworks Inc. (NASDAQ:ZYME), Novartis AG (NYSE:NVS), and Regeneron Pharmaceuticals, Inc. (NASDAQ:REGN).
The industry's focus on combination strategies and novel targets is yielding promising clinical results, with antibody-drug conjugates, metabolic inhibitors, and immune-activating platforms demonstrating enhanced efficacy when paired with complementary mechanisms[2]. Major pharmaceutical companies are investing heavily in radioligand therapy and precision medicine infrastructure, while emerging biotech firms leverage genetic screening to identify patient populations most likely to benefit from targeted interventions. These dynamics create compelling opportunities for companies with diversified pipelines addressing both common and rare cancers through validated biological mechanisms, particularly those approaching key clinical readouts and regulatory milestones in high-value indications.
GT Biopharma, Inc. (NASDAQ:GTBP) is a clinical-stage immunotherapy company making significant progress in its fight against difficult-to-treat cancers. The San Francisco-based biotech has been advancing its lead drug candidate, GTB-3650, through a Phase 1 clinical trial targeting blood cancers that have stopped responding to other treatments. In August, the company successfully moved into Cohort 3 after formal safety reviews of the first two patient groups showed no safety or tolerability problems. The trial had treated five patients by mid-August, with encouraging early signals of immune system activation.
"We are pleased with the enrollment momentum in our Phase 1 clinical trial evaluating GTB-3650 in cancer patients, which continues to advance on schedule," said Michael Breen, Executive Chairman and Chief Executive Officer of GT Biopharma. "Moving into the third dose cohort after a successful safety review and encouraging early evidence of immunological activity, mark important steps forward in the development of GTB-3650. We look forward to sharing more data later this year to reinforce the ability of our TriKE constructs to activate endogenous NK cells, and the potential for broader utility with other targets to treat solid tumors (GTB-5550) and autoimmune indications (GTB-7550)."
The Phase 1 trial is testing GTB-3650 in patients with relapsed or refractory CD33-expressing blood cancers, including acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS). These are patients whose cancers have come back or never responded to standard therapies. The drug works by activating the body's own natural killer cells to attack cancer cells. Patients receive the treatment through continuous infusions in two-week cycles, alternating two weeks on and two weeks off, for up to four months based on how well they're responding.
What makes the early data particularly interesting is the biomarker evidence. Multiple blood tests from the first four patients showed measurable increases in natural killer cell activity and expansion. This suggests the drug is doing exactly what it was designed to do—wake up the immune system and direct it against cancer. GT Biopharma expects to release more detailed Phase 1 results later this year after completing additional dose cohorts.
Beyond blood cancers, GT Biopharma has a second drug candidate moving toward the clinic. GTB-5550 targets a protein called B7H3 that appears in many different types of solid tumors, including breast, lung, ovarian, head and neck, pancreatic, bladder, and prostate cancers. The company expects to submit its application to start human testing of GTB-5550 during the fourth quarter of this year. Unlike many cancer immunotherapies that require lengthy hospital infusions, GTB-5550 is being developed as a simple injection that patients could potentially give themselves at home, similar to insulin shots.
Both drug candidates are built on GT Biopharma's proprietary TriKE platform, which uses specialized antibody fragments originally discovered in camels and llamas. These molecules are smaller and more stable than traditional antibodies, allowing them to work more effectively. GT Biopharma holds an exclusive worldwide license from the University of Minnesota to develop and commercialize therapies using this technology.
As of June 30, 2025, GT Biopharma reported cash and cash equivalents of approximately $5.3 million, which management expected would fund operations into the first quarter of 2026.

IDEAYA Biosciences, Inc. (NASDAQ:IDYA) has reported positive Phase 1/2 data for its combination of IDE397, a potential first-in-class MAT2A inhibitor, with Gilead's Trodelvy® in MTAP-deletion urothelial cancer, achieving an overall response rate of 57% at the higher dose level. The trial enrolled patients with late-line MTAP-deletion urothelial cancer, where MTAP-deletion is estimated to occur in approximately 25-30% of urothelial cancer patients, with 68% of participants having progressed after two or more prior therapies.
"We are pleased with the progress we are making with the Trodelvy and IDE397 combination and are encouraged by the early response rate data we are seeing in previously treated MTAP-deleted urothelial cancer," said Darrin Beaupre, Chief Medical Officer of IDEAYA Biosciences. "These results set the stage for further testing of the combination in non-small cell lung cancer, where we have just dosed the first patient in our clinical trial."
The combination demonstrated a manageable safety profile consistent with known adverse events of both drugs as single agents, with no treatment-related serious adverse events observed at the recommended expansion dose. IDEAYA is targeting selection of the recommended Phase 2 dose by end of 2025, with the next update planned for a medical conference in the first half of 2026.
