Research Findings
Conducted under the direction of Shay Bracha, DVM, MS, DACVIM (Oncology) at Ohio State’s College of Veterinary Medicine, the study examined Telomir-Zn across three osteosarcoma cell line models: HOS (human), D17 (canine), and Abrams (canine). Researchers evaluated the dose-dependent anti-tumor activity of the compound across all three models.

All three osteosarcoma cell lines demonstrated growth inhibition at similar low drug concentrations. "Osteosarcoma in large-breed dogs remains devastating, with limited treatment options and poor outcomes," noted Bracha, an associate professor at The Ohio State University College of Veterinary Medicine. "These findings suggest Telomir-Zn may offer a meaningful therapeutic opportunity for veterinary patients. The consistency of anti-tumor activity across both canine and human cell lines is particularly compelling because it positions us to explore efficacy in naturally occurring canine osteosarcoma—a model that could accelerate development for both animals and humans."

These results validate the therapeutic potential of Telomir-Zn in osteosarcoma and support further translational investigation.

Osteosarcoma: An Unmet Clinical Need
Osteosarcoma is the most common primary bone malignancy in children and young adults. Despite decades of chemotherapy-based treatment, survival rates for metastatic disease remain below 30%, with minimal improvement over three decades. In veterinary medicine, osteosarcoma is similarly devastating in large-breed dogs, accounting for the majority of primary bone tumors.

The biological similarities between canine and human osteosarcoma, including genetics, tumor biology, and therapeutic response patterns, make the canine model one of the most clinically predictive disease models available for translational research.

Strategic Development Pathway
Based on these findings, Telomir is assessing osteosarcoma development in canine models as a potential therapeutic pathway, which could support both veterinary indication development and translational advancement toward human osteosarcoma:

Track 1: TNBC in Humans — The company’s TNBC program is advancing toward site initiation and Phase 1/2 patient enrollment under an active IND cleared by the FDA, targeting advanced or metastatic triple-negative breast cancer.
Track 2: Osteosarcoma in Dogs — Based on these preclinical findings, Telomir is in conversations with The Ohio State University College of Veterinary Medicine and assessing next steps for a potential in vivo efficacy study in canine osteosarcoma. Such research could accelerate clinical development in canine and human osteosarcoma.
While the company’s immediate focus remains advancing TNBC toward site initiation and Phase 1/2 patient enrollment, these preclinical findings position potential osteosarcoma development in canine models as a strategic opportunity. If pursued, such a dual-pathway approach could expand the therapeutic indication profile while advancing our platform.

The Iron-Modulation Platform
Telomir-Zn targets intracellular iron and copper homeostasis to modulate epigenetic pathways. The mechanism involves disruption of intracellular labile iron pools and inhibition of iron-dependent histone demethylases (KDMs), which reverses cancer-associated epigenetic silencing.

The company’s strategic focus is triple-negative breast cancer, where the TNBC program is advancing toward site initiation and Phase 1/2 patient enrollment. The osteosarcoma preclinical findings provide an additional translational opportunity to validate the mechanism in a naturally occurring disease model (canine) while simultaneously advancing the lead TNBC indication.

PDS Biotech Announces Initial Closing of up to $22.3 Million PIPE Financing and the Appointment of Dr. Patrick Soon-Shiong to Its Board of Directors

On September 14, 2026 PDS Biotechnology Corporation (Nasdaq: PDSB) ("PDS Biotech" or the "Company"), a clinical-stage biotechnology company focused on developing targeted immunotherapies for cancer, reported the initial closing (the "Initial Closing") of the Company’s Private Investment in Public Equity ("PIPE") transaction. The round was led by Nant Capital, LLC ("Nant") with additional participation by current investors. The PIPE also consists of a contingent milestone closing (the "Milestone Closing") as described below.

At the Initial Closing, the Company sold (i) shares of the Company’s common stock (the "Private Placement Shares") or, at the election of an investor, pre-funded warrants in lieu of such shares ("Pre-Funded Warrants"), and (ii) accompanying common stock purchase warrants ("Common Warrants"). Each unit consisting of one Private Placement Share and a Common Warrant to purchase one-half of one Private Placement Share ("Common Warrants") was issued for $0.2825 (the "Share Unit Purchase Price"), and each unit consisting of one Pre-Funded Warrant to purchase one share of Common Stock and a Common Warrant to purchase one-half of one share of Common Stock was issued for $0.28217 (the "Pre-Funded Unit Purchase Price"). The aggregate gross proceeds and the aggregate number of Private Placement Shares, Pre-Funded Warrants and Common Warrants issued as part of the Initial Closing were approximately $11.3 million, and 16,502,870, 23,498,156 and 20,000,514, respectively.

The Company intends to use the net proceeds from the private placement to repay outstanding indebtedness and for working capital and general corporate purposes, including the continued development of its clinical programs, research and development, and general and administrative expenses. The Company also expects that the PIPE will advance PDS0301 (also referred to as PDS01ADC or NHS-IL12) into late-stage clinical development, based on recent promising interim Phase 2 clinical trial data in microsatellite stable (MSS) and mismatch repair-proficient (pMMR) metastatic colorectal cancer (mCRC), types of colorectal cancer that have not responded well to treatment with immunotherapy. Patients with MSS and pMMR mCRC with liver metastases historically have dire treatment outcomes, with median overall survival of less than 12 months.* In a National Cancer Institute (NCI) led Phase 2 trial, the addition of PDS0301 to standard of care therapy in 22 patients was well tolerated, and demonstrated deep and long-lasting tumor shrinkage and survival, with 80% of patients surviving for at least 24 months.

At the Milestone Closing, which will be triggered by the Company’s submission of a registrational Phase 3 clinical trial protocol for PDS0301 designed in collaboration with Nant to the FDA, Nant and AB Group Ltd. will be obligated to purchase and the Company will be obligated to issue to each of Nant and AB Group Ltd., shares of common stock or Pre-Funded Warrants in lieu thereof for an aggregate purchase price of $10,000,000 and $1,000,000, respectively, subject to the satisfaction or waiver of the applicable closing conditions. The number of securities purchased by any investor will be subject to a 19.9% beneficial ownership limitation.

In addition to the PIPE transaction, and for additional consideration, the Company granted NantWorks, LLC, an affiliate of Nant, a one-year exclusive right to negotiate an exclusive license to PDS0101, the Company’s novel investigational human papilloma virus targeted immunotherapy that stimulates a potent targeted T cell attack against HPV-positive cancers.

Ataraxis AI Publishes Landmark Studies Showing Causal AI Predicts Chemotherapy Benefit in Multiple Solid Tumors

On September 14, 2026 Ataraxis AI, a company building clinical AI tools to personalize cancer care, reported scientific breakthroughs and validation results of Ataraxis’s AI models.

Ataraxis developed breakthrough causal AI methods that learn from large-scale, longitudinal data to predict patient outcomes in counterfactual treatment scenarios. These methods were encompassed in an AI world model called Ataraxis Tau.
Ataraxis Tau was applied to breast cancer, developing a model simulating patient outcomes with and without adjuvant chemotherapy.
In three clinical validation studies encompassing 18,426 patients, including analyses of Phase 3 randomized controlled trials TAILORx and UNIRAD, Ataraxis’s models were successfully confirmed to be prognostic and predictive of chemotherapy benefit.
Ataraxis Tau generalizes its prognostic and predictive capabilities zero-shot to multiple other solid tumors beyond breast cancer in an analysis of 6,692 patients across 16 other cancer types.
Instead of relying on population-level patient characteristics and biomarkers, Ataraxis developed causal AI methods that simulate individual patient outcomes in counterfactual treatment scenarios. These methods learn to recover treatment effects from routine, longitudinal clinical data as well as from randomized trials. These methods have been incorporated into Ataraxis’s broader AI world model, dubbed Ataraxis Tau.

The first version of Ataraxis Tau was trained primarily with breast cancer data to predict outcomes in patients with hormone receptor-positive, HER2-negative early-stage breast cancer. Specifically, Tau was originally trained to predict outcomes in patients treated with and without chemotherapy. This design allows Ataraxis, for the first time ever, to identify patients who–despite having high baseline risk of recurrence–might not benefit from adjuvant chemotherapy and who might be considered for other adjuvant therapy options.

Ataraxis’s capabilities in breast cancer were confirmed in three clinical validation studies released today: analyses of TAILORx and UNIRAD Phase 3 trials and a real-world multi-institutional study encompassing over 10,000 patients from 17 cohorts in 10 countries.

In the analysis of the TAILORx trial, Ataraxis was found to be predictive of adjuvant chemotherapy benefit (interaction p = 0.016) within the intermediate-risk-score group. Today, these patients are de-escalated to endocrine therapy alone. In Ataraxis’s analysis, the AI model identified patients who benefit from adjuvant chemotherapy with improved 5-year disease-free survival (95.2% vs. 89.6%), while patients predicted to not benefit from chemotherapy had no significant difference in outcomes.
In the analysis of the UNIRAD trial, Ataraxis identified patients within clinically high-risk, node-positive patients who have good long-term outcomes with standard of care therapy. Today, these patients are considered for escalation with drugs such as adjuvant CDK4/6 inhibitors, with no validated biomarkers to help in choices between adjuvant therapy options. Additionally, Ataraxis’s AI model was found to be predictive (p=0.01) of everolimus (mTOR inhibitor) benefit in an identified subgroup.
In a study describing the development and validation of a causal AI model for chemotherapy benefit, Ataraxis included data encompassing 11,135 breast cancer patients from 17 cohorts in 10 countries. The AI model had near-perfect calibration across the full range of predicted risk and was predictive of chemotherapy benefit (p<0.001). Additionally, within a subgroup of 983 patients tested with Oncotype DX, a legacy molecular assay, Ataraxis’s AI model had more robust predictive performance (p=9.7 × 10⁻⁴ versus p=0.025).
Finally, prognostic and predictive capabilities of the Ataraxis Tau world model generalized to cancers it was never trained on. In the real-world study, Ataraxis Tau was applied zero-shot to 6,692 patients spanning 16 cancer types. Ataraxis Tau was prognostic in 11 tumor types, including gastrointestinal cancers, lung cancers, skin cancers, and others. Chemotherapy benefit prediction also transferred zero-shot to five of the seven cancers treated with platinum- or taxane-based regimens, which are shared with breast chemotherapy, showing that Tau learned a treatment-specific predictive signal.

"Today’s results mark a major milestone for Ataraxis. We have previously shown that our AI models can accurately predict outcomes and treatment response in breast cancer. Now, we have gold-standard evidence supporting those findings and the broader clinical use of our tools. These results also bring us closer to a new era of personalized treatment. Our AI world model, Ataraxis Tau, can predict recurrence and treatment benefit across cancer types. As we scale Tau, it will serve as the foundation for future tools designed to help personalize treatment for every cancer patient," said co-founder and CEO of Ataraxis AI, Jan Witowski, MD, PhD.

This distinguishes the result from prior pan-cancer analyses of AI pathology models, which have reported performance only after fitting or fine-tuning a separate model for each cancer type. A causal model trained on breast cancer alone identified risk and chemosensitivity across most other cancers, suggesting it has learned determinants of treatment response that are shared across malignancies rather than specific to one disease.

Ataraxis is building on that foundation, extending individualized benefit prediction to additional therapies and tumor types and working toward a causal model of treatment response that spans oncology, so that any patient facing a treatment decision can be told not just how aggressive their cancer is, but what a given therapy is likely to do for them.

Biomunex Announces the Upcoming Start of Clinical Development of IPN60330, the First MAIT Engager, a New Therapeutic Class in Oncology, Following the Completion of the FDA Review Period

On September 14, 2026 Biomunex Pharmaceuticals, a biopharmaceutical company specialized in the discovery and development of innovative therapeutic approaches, reported that the U.S. Food and Drug Administration (FDA) has completed its Investigational New Drug (IND) review period for Ipsen’s IPN60330 (formerly BMX-502), the first MAIT cell engager (also referred to as a "MAIT engager") based on Biomunex’s proprietary BiXAb technology platforms, and for which Biomunex and Ipsen announced an exclusive global licensing agreement for development, manufacture and commercialization rights in 2024.

This key step is the result of an intensive preclinical development effort, encompassing full drug bioproduction for the Phase 1 trial, regulatory studies and animal toxicology studies, conducted by the Biomunex team in partnership with Ipsen. It marks the upcoming initiation of Ipsen’s Phase I clinical trial in the USA, a significant step forward in the development of this novel therapeutic class in immuno-oncology.

IPN60330 is a bispecific antibody designed to selectively engage and activate MAIT cells (Mucosal-Associated Invariant T cells), a subset of T cells present throughout the body, which are particularly enriched in mucosal and barrier tissues, and targets the GPC3 tumor antigen to kill cancer cells. GPC3 is a clinically validated target, highly expressed across several cancer types.

The completion of the FDA review period is a further demonstration of the quality of Biomunex’s proprietary BiXAb technologies. This first MAIT engager should overcome some of the limitations of classical pan-T cell engagers, which activate all T cells, including regulatory T cells, and can induce cytokine release syndrome, a potentially serious dose-limiting toxicity that represents a true problem for physicians and their cancer patients. MAIT engagers have the potential to provide a broader therapeutic window compared to classical pan-T cell engagers for treating specific tumor types. Moreover, an improved therapeutic window with MAIT engagers should permit a stronger response from the adaptive immune system leading to improved and durable responses.

This new milestone has triggered a milestone payment linked to the completion of the FDA IND review period ahead of the upcoming entry into clinical development, under the exclusive global licensing agreement entered into between Ipsen and Biomunex in November 2024. In the context of this agreement, Biomunex is eligible to receive up to $610 million in total, including an upfront already received, contingent upon successful development, regulatory and commercial milestones, in addition to tiered global royalties on sales.

"The upcoming start of the clinical development program in the United States for IPN60330 is a recognition of the quality of our collaboration with Ipsen. Moreover, that’s a major milestone in our development, demonstrating the strength of our BiXAb technology platforms, as well as the expertise of our teams in generating breakthrough innovation," said Dr Simon Plyte, CSO of Biomunex. "It finally underscores our ability to develop innovative programs in partnership with a world-renowned pharmaceutical partner, with the potential to open new avenues in cancer immunotherapy," added Dr Pierre-Emmanuel Gerard, founder, President and CEO of Biomunex.
