"Advancing [Ac-225]-RTX-2358 into the clinic represents a major milestone for our company and reflects years of dedicated and innovative work by our team," said John Babich, Ph.D., President and Chief Scientific Officer of Ratio. "The preclinical and early human experience point to a strong therapeutic profile for our drug in sarcoma, with encouraging signs of activity in additional FAP-expressing cancers. Initiation of this trial marks the entry of our first therapeutic into the clinic and underscores our commitment to developing innovative radiotherapies that can bring new treatment options to cancer patients."

"This study represents an important step in exploring a novel therapeutic approach for patients with relapsed or refractory sarcoma, a population with limited treatment options," said Dr. Sandra D’Angelo, MD, a Medical Oncologist specializing in the care of patients with sarcoma at Memorial Sloan Kettering Cancer Center. "Radiopharmaceuticals are transforming cancer treatment by delivering radiation directly to tumors with far greater precision and decreased side effects. Ratio’s technology is designed to further enhance these benefits, and we look forward to exploring the potential of [Ac-225]-RTX-2358 to provide a meaningful impact for patients suffering from this challenging disease."

About the ATLAS Trial

The ATLAS trial is a Phase 1/2 open-label clinical trial (clinicaltrials.gov identifier, NCT07156565) designed to assess the safety, tolerability, dosimetry, biodistribution, pharmacokinetics, and preliminary anti-tumor activity of [Ac-225]-RTX-2358, a highly selective, FAP targeted radiotherapeutic labeled with Actinium 225, in patients with relapsed or refractory soft tissue sarcomas that express FAP.

The study consists of two phases: an ascending administered activity phase (Phase 1) and an expansion phase (Phase 2). For patients to be eligible to receive treatment, FAP expression will be assessed using a [Cu-64]-LNTH-1363S PET scan. In the Phase 1 portion, patients with FAP positive sarcomas will receive intravenous injections of [Ac-225]-RTX-2358 once every eight weeks, for up to six treatment cycles over a 12-month period. Using a standard 3+3 dose escalation design, participants will be assigned to one of three groups, each receiving an increasing dose level to determine the maximum tolerated dose and establish a recommended dose for the expansion phase. Cohort expansion will be allowed to a max of 10 patients per cohort, enabling up to 26 patients to be treated and evaluated during the Phase 1 portion of the trial. This will allow better characterization of safety and tolerability as well as the assessment of preliminary efficacy. Safety data from each group will be reviewed by an independent Safety Review Committee before dose escalation proceeds. The Phase 2 portion of the study will evaluate the efficacy and safety of [Ac-225]-RTX-2358 in up to 50 patients. [Ac-225]-RTX-2358 is being manufactured by Pharmalogic. [Cu-64]-LNTH-1363S is being provided by Lantheus and manufactured by PharmaLogic.

Dr. D’Angelo provides consulting and advisory services to Ratio Therapeutics.

INBRX-106

Inhibrx has recruited 46 of the 60 patients in the randomized Phase 2 portion of the Phase 2/3 clinical trial evaluating INBRX-106 in combination with Keytruda versus Keytruda as a first-line treatment for patients with unresectable or metastatic HNSCC. Inhibrx expects to complete enrollment in the Phase 2 portion of the trial during the first quarter of 2026. This trial is recruiting patients who have not received prior systemic therapy for unresectable or metastatic HNSCC and have tumor PD-L1 CPS expression equal to or greater than 20. Patients are randomized one to one to either INBRX-106 in combination with Keytruda or Keytruda. The primary endpoint of the Phase 2 portion of this trial is overall response rate, supported by secondary endpoints of duration of response, progression free survival and safety.

In November 2025, Inhibrx completed enrollment of the Phase 1/2 trial evaluating 34 patients in checkpoint inhibitor refractory or relapsed NSCLC in combination with Keytruda. Primary endpoints for this cohort are objective response rate, disease control rate, duration of response and safety.

The current datasets for both HNSCC and NSCLC lack sufficient maturity to support an interpretation and conclusion on the viability of this program. Inhibrx expects that in the second half of 2026, the data should be mature enough to inform whether INBRX-106, in combination with Keytruda, demonstrates superior efficacy and sustained clinical benefit relative to the current standard of care.

KEYTRUDA is a registered trademark of Merck Sharp & Dohme Corp.

Ozekibart (INBRX-109)

In late October 2025, Inhibrx completed enrollment of 44 patients in the expansion cohort of the Phase 1/2 trial evaluating ozekibart in combination with FOLFIRI in heavily pretreated (third and fourth line) advanced or metastatic, unresectable colorectal cancer. As previously reported, ozekibart in combination with FOLFIRI was well tolerated, with durable responses and a high rate of disease control. The progression free survival data should be mature in the second quarter of 2026, and we plan to provide an update at that time.

Inhibrx expects to complete enrollment in the Phase 1/2 trial of ozekibart in combination with irinotecan and temozolomide (IRI/TMZ) for advanced or metastatic, unresectable, relapsed, or refractory Ewing sarcoma in the second quarter of 2026. If the current response and duration trends observed continue, Inhibrx plans to meet with the FDA in the second half of 2026 to discuss an accelerated approval pathway for this indication.

About INBRX-106

INBRX-106 is a precisely engineered hexavalent sdAb-based therapeutic candidate targeting OX40, designed to be an optimized agonist of this co-stimulatory receptor. It is currently being investigated in combination with Keytruda in patients with locally advanced or metastatic solid tumors, specifically HNSCC and NSCLC.

About ozekibart (INBRX-109)

Ozekibart is a precision-engineered, tetravalent death receptor 5 (DR5) agonist antibody designed to exploit the tumor-biased cell death induced by DR5 activation. Inhibrx read out a successful single agent registration study in chondrosarcoma and a BLA filing is expected in early Q2 of 2026. Additionally, Inhibrx is evaluating ozekibart in patients diagnosed with colorectal cancer and Ewing sarcoma.

In addition, Bicycle announced a collaboration with United Kingdom National Nuclear Laboratory (UKNNL), pursuant to which it plans to extract 228Th from the RepU obtained from NDA. The extracted 228Th will then be further processed into 224Ra and loaded into a bespoke 212Pb generator being developed exclusively for Bicycle by SpectronRx. 212Pb is a radioisotope and one of the more potent therapeutic payloads against cancer cells known as Targeted Alpha Therapy (TAT).

Collectively, this bespoke set of arrangements is designed to support the potential discovery, development, and commercial supply of a portfolio of Bicycle Radioconjugates (BRC) containing 212Pb.

"Cancer is a disease that affects millions worldwide, and tears too many families apart. Breakthroughs in medical science are giving more cancer patients and their loved ones hope, and this unique partnership could help take that work even further. Turning nuclear material into cutting-edge cancer treatments sounds like science fiction – but thanks to the brilliance of scientists, researchers and doctors, it could be a life-saving reality. Work like this shows exactly why we’re determined to support our life sciences innovators to make groundbreaking new treatments possible," said Liz Kendall, Secretary of State.

"These new collaborations are testaments to the potential of Bicycle to advance a differentiated and exciting isotope agnostic radiopharmaceuticals portfolio. We believe we now have the resources and infrastructure we need to create the world’s first end-to-end 212Pb radiopharmaceutical ecosystem from discovery through development to commercial supply. We believe the potential of BRCs and our ability to incorporate the appropriate isotopes for specific patient needs is unique and creates significant value-creating capabilities," said Mike Hannay, D.Sc., FRPharmS, chief product and supply chain officer of Bicycle Therapeutics. "We are incredibly grateful to the UK government for their recognition of Bicycle’s potential to develop BRCs with a 15-year access agreement for reprocessed uranium, and to our partners SpectronRx with whom we are developing a bespoke 212Pb generator. We look forward to advancing these dynamic collaborations and developing our pipeline of radiopharmaceuticals with the potential of improving lives for cancer patients around the globe."

"I am delighted with the progress we are making in establishing ourselves as a potential leader in radiopharmaceutical R&D. Today’s announcement builds on our previous announcements concerning our agreement with Eckert & Ziegler to supply a range of radioisotopes for the manufacture of BRC products as well as the formation of our Research and Innovation Advisory Board (RAB) comprising some of the worlds most esteemed experts in radiopharmaceuticals," said Bicycle Therapeutics CEO Kevin Lee, Ph.D. "As we continue to advance our emerging BRC pipeline, currently with novel targets EphA2 and MT1-MMP, we look forward to presenting initial EphA2 human imaging data in the first half of 2026 and initiating our own Bicycle study in 2026."
