RenovoRx Highlights Peer-Reviewed Publication of Pharmacokinetic and Pharmacodynamic (PK/PD) Data Supporting TAMP™ Platform’s Targeted Drug-Delivery in Locally Advanced Pancreatic Cancer

PK/PD Data is from a Sub-Study in the Phase III TIGeR-PaC Clinical Trial 

The Study Shows Approximately 51% Tumor-Site Drug Extraction, Decreased Systemic Exposure, and Significant Correlation Between Drug Metabolite Levels and Tumor Marker Reduction

MOUNTAIN VIEW, Calif., Aug. 25, 2026 (GLOBE NEWSWIRE) -- RenovoRx, Inc. (“RenovoRx” or “the Company”) (Nasdaq: RNXT), a life sciences company developing innovative targeted oncology therapies and commercializing RenovoCath^®, a patented, FDA-cleared drug-delivery device, today announced the publication of pharmacokinetic and pharmacodynamic (PK/PD) data from a sub-study of its ongoing Phase III TIGeR-PaC clinical trial (NCT03257033) in the journal Cancer Chemotherapy and Pharmacology.

The data shows that TAMP (Trans-Arterial Micro-Perfusion)-mediated delivery concentrated chemotherapy at the tumor site, extracting roughly 51% of the drug locally before it entered the bloodstream, meaningfully lowering systemic exposure in a way that could reduce systemic side effects. In addition, a statistically significant correlation between the drug's local metabolism and a drop in the CA 19-9 tumor marker provided an early indication of improved drug penetration into the tumor area and potential tumor response with intra-arterial delivery.

RenovoRx also recently announced the closing of enrollment of the TIGeR-PaC trial, with trial completion expected in the first half of 2027 and expected initial top line data availability in the second half of 2027.

“The findings from this PK/PD study provide additional meaningful mechanistic support for our TAMP platform’s targeted drug-delivery approach,” said Ramtin Agah, M.D., Executive Chairman, Chief Medical Officer, and Founder of RenovoRx. “The results provide direct pharmacokinetic evidence supporting TAMP’s potential to deliver chemotherapy more selectively to the tumor while limiting systemic exposure. These findings strengthen TAMP, enabled by our RenovoCath device, as a differentiated approach to improving the therapeutic index of chemotherapy in patients with LAPC.”

The PK/PD study, titled “Pharmacokinetic and Pharmacodynamic Sub-study of Trans-arterial vs Intravenous Gemcitabine in the TIGeR-PaC Phase 3 Clinical Trial,” compared the systemic drug levels of intra-arterial gemcitabine (IAG) delivered via TAMP using RenovoCath against standard intravenous gemcitabine (IVG) delivered systemically in 16 patients with LAPC across six clinical sites (11 patients received IAG; 5 received IVG). Funding for this study was provided by RenovoRx.

Key Findings:

• Reduced systemic exposure: IAG resulted in significantly lower total systemic gemcitabine exposure compared to IVG, despite being administered at a 50% higher infusion concentration rate, supporting the potential of TAMP to concentrate therapy at the intended treatment site while limiting systemic exposure.
• Substantial local drug extraction: A targeted extraction ratio of 0.511 was observed (derived from a bioavailability estimate of 0.489), indicating approximately 51% of the intra-arterially delivered gemcitabine was extracted at the site of intra-arterial delivery before entering systemic circulation. This finding provides direct pharmacokinetic evidence supporting the targeted drug-delivery mechanism underlying the TAMP platform.
• Tumor marker response: A statistically significant correlation was observed between higher systemic levels of dFdU and greater reductions in CA 19-9 tumor marker levels following IAG treatment (Pearson’s r = -0.75; P = 0.034; based on eight evaluable patients, with three excluded for normal baseline CA 19-9). dFdU is gemcitabine’s inactive metabolite, and higher dFdU levels are consistent with rapid local uptake and metabolism of gemcitabine at the treatment site, providing an initial pharmacodynamic signal linking drug exposure with a biomarker of tumor response.
• Consistent delivery across arterial sites: No statistically significant differences in gemcitabine or dFdU pharmacokinetic parameters were observed based on IAG delivery site, whether administered via the superior mesenteric artery or the celiac artery.
  

The Company believes this data provides evidence that IAG delivery via the TAMP therapy platform achieves meaningful local drug extraction while reducing systemic gemcitabine exposure, supporting RenovoRx’s differentiated approach to targeted intra-arterial chemotherapy in patients with LAPC.

About RenovoCath
Based on its FDA clearance, RenovoCath^® is intended for the isolation of blood flow and delivery of fluids, including diagnostic and/or therapeutic agents, to selected sites in the peripheral vascular system. RenovoCath is also indicated for temporary vessel occlusion in applications including arteriography, preoperative occlusion, and chemotherapeutic drug infusion. For further information regarding our RenovoCath Instructions for Use (“IFU”), please see: https://renovorx.com/wp-content/uploads/2026/06/IFU-10004-Rev.-H-Universal-IFU.pdf.

About the TIGeR-PaC Clinical Trial
TIGeR-PaC is an ongoing Phase III randomized multi-center trial evaluating the proprietary TAMP™ (Trans-Arterial Micro-Perfusion) therapy platform for the treatment of locally advanced pancreatic cancer (LAPC). RenovoRx’s first investigational drug-device combination product candidate, using the TAMP therapy platform enabled with the Company’s FDA-cleared RenovoCath^® device, is designed for the intra-arterial administration of chemotherapy, gemcitabine (IAG).

About RenovoRx, Inc.
RenovoRx, Inc. (Nasdaq: RNXT) is a life sciences company developing innovative targeted oncology therapies and commercializing RenovoCath^®, a patented, U.S. Food and Drug Administration (FDA)-cleared local drug-delivery device, targeting high unmet medical needs. RenovoRx’s patented Trans-Arterial Micro-Perfusion (TAMP™) therapy platform is designed for targeted therapeutic delivery across the arterial wall near the tumor site to bathe the target tumor, while potentially minimizing a therapy’s toxicities versus systemic intravenous therapy. RenovoRx’s novel approach to targeted treatment offers the potential for increased safety, tolerance, and improved efficacy, and its mission is to transform the lives of cancer patients by providing innovative solutions to enable targeted delivery of diagnostic and therapeutic agents.

RenovoRx is actively commercializing its TAMP technology and FDA-cleared RenovoCath as a standalone device. For its first full year of commercial efforts in 2025, RenovoRx generated approximately $1.1 million in RenovoCath sales, followed by record quarterly revenue of $909,000 in the second quarter of 2026. RenovoRx is actively working to expand the number of medical institutions initiating new RenovoCath orders, including esteemed, high-volume National Cancer Institute-designated centers.

RenovoRx is also evaluating its novel drug-device combination oncology product candidate intra-arterial gemcitabine delivered via RenovoCath (known as IAG) in the ongoing Phase III TIGeR-PaC trial. IAG is being evaluated by the Center for Drug Evaluation and Research (the drug division of the FDA) under a U.S. investigational new drug application that is regulated by the FDA’s 21 CFR 312 pathway. IAG utilizes RenovoCath, which is FDA-cleared for temporary vessel occlusion in applications including arteriography, preoperative occlusion, and chemotherapeutic drug infusion. RenovoRx achieved full enrollment in the TIGeR-PaC trial in August 2026, with completion of the trial expected in the first half of 2027 and topline data readout expected in the second half of 2027.

The IAG combination product candidate, enabled by the RenovoCath device, is currently under investigation and has not been approved for commercial sale. RenovoCath with gemcitabine received Orphan Drug Designation (ODD) for pancreatic cancer and bile duct cancer, and oxaliplatin has received ODD for pancreatic cancer, each of which provides seven years of market exclusivity upon new drug application approval by the FDA.
