The PREDICTT trial is an investigator-led single-arm, prospective, interventional study designed to evaluate how PEDD impacts tumor targeting and radiation dose distribution. Investigators at The University of Texas MD Anderson Cancer Center will assess the use of the TriNav Infusion System in conjunction with Y90 radioembolization therapy. Specifically, the trial will measure changes in CT-based tumor-to-normal liver ratios and assess how these changes correlate with tumor dose and treatment outcomes.

Advancing Precision Delivery in Liver-Directed Therapy

Y90 radioembolization is a widely used treatment for unresectable liver tumors. However, optimizing delivery to maximize tumor dose while minimizing exposure to healthy liver tissue remains a critical challenge. The PREDICTT study aims to address this by evaluating the TriNav Infusion System, a Pressure-Enabled Drug Delivery device designed to improve microsphere distribution within tumors.

Study Design and Objectives

The PREDICTT (Prospective Evaluation of Pressure-Enabled Delivery and Alterations in CT-Based Tumor-to-Normal Liver Ratio and Tumor Dose) trial is an investigator-led study evaluating the impact of pressure-enabled delivery using the TriNav Infusion System in patients undergoing Y90 radioembolization for liver tumors. The PREDICTT trial will enroll approximately 20 adult patients with unresectable primary or metastatic liver tumors who are eligible for Y90 radioembolization. The trial is led by principal investigator Peiman Habibollahi, M.D., associate professor of Interventional Radiology at UT MD Anderson.

Key objectives include:

Evaluate changes in CT-based tumor-to-normal liver enhancement ratios using the TriNav Infusion System
Correlate imaging-based measurements with tumor dose and microsphere distribution
Evaluate relationships between imaging metrics and post-treatment SPECT/CT findings
Assess safety of the TriNav Infusion System [with Y90] in liver directed therapy
Strengthening Clinical Collaboration

The launch of PREDICTT underscores the continued collaboration between TriSalus Life Sciences and UT MD Anderson.

"This study represents an important step toward optimizing locoregional therapies through advanced delivery technologies," said Richard Marshall, MD at Chief Medical Officer, TriSalus Life Sciences. "We are proud to collaborate with UT MD Anderson to generate clinical evidence that could redefine how Y90 therapies are delivered."

About BTX-9341

BTX-9341 is a first-in-class, oral degrader of CDK4/6, important targets for a range of cancers and clinically validated in HR+/HER2- breast cancer. In preclinical breast cancer models, BTX-9341 demonstrated superiority to CDK4/6 inhibitors through potent and highly selective catalytic degradation of CDK4 and CDK6, robust inhibition of CDK2 and Cyclin E transcription, cell cycle arrest, and ultimately superior in vivo efficacy in breast cancer xenografts. Beyond this increased efficacy potential, BTX-9341 is differentiated from CDK4/6 inhibitor approaches through the ability to overcome key resistance mechanisms that limit the impact of inhibitors in second line HR+/HER2- metastatic breast cancer.

PEP08 received clinical clearance in June 2025 and is currently in Phase I evaluation for solid tumors in Australia and the Taiwan region. The enrollment milestone underscores XtalPi’s ability to deliver differentiated molecules with strong drug-like properties, while demonstrating the program’s steady clinical advancement.

Leveraging XtalPi’s integrated quantum physics-, AI-, and robotics-powered platform, PEP08 was designed to overcome the dose-limiting hematological toxicities seen with first-generation PRMT5 inhibitors. The molecule exploits an innovative MTA-cooperative binding mode to specifically target MTAP-deleted tumors—a genomic alteration found in 10-15% of all human cancers, with higher frequencies observed in NSCLC, pancreatic cancer, glioblastoma, and more. Preclinical data presented at 2025 AACR (Free AACR Whitepaper) show PEP08 achieving superior efficacy compared to other clinical-stage MTA-cooperative PRMT5 inhibitors across multiple MTAP-deleted tumor models, supporting a potential best-in-class profile.

Driven by the success of PEP08 at the drug discovery stage, the partnership expanded into a second project. By combining PharmaEngine’s deep oncology expertise with XtalPi’s AI and robotics molecular design engine, the duo aims to capture additional market share in the synthetic lethality space.

Synthetic lethality is widely recognized as challenging yet highly promising frontier in oncology. According to Globocan and industry data, the global market is expected to grow from $4.2 billion to $17.6 billion by 2033, at a 17.3% CAGR. In recent years, several early-stage licensing deals in this space have exceeded $1 billion USD, further underscoring the immense clinical value and commercial appetite for this category.

The clinical advancement of PEP08 and the ongoing collaboration of the second project serve as a dual validation of XtalPi’s AI+robotics discovery engine. By repeatedly meeting rigorous benchmarks in complex target spaces, XtalPi has built a reproducible innovation model that turns deep know-how into high-value clinical assets. Underpinned by a milestone-sharing structure, this model tightly aligns the platform’s evolution with clinical success, quickly translating biological insights into tangible impact for partners and patients around the world.

Dr. Shuhao Wen, Chairman of XtalPi commented, "The clinical progress of PEP08 and the ongoing collaboration of the second project are testaments to the synergy between our teams, and highlights the reliability of XtalPi’s R&D platform in tackling complex targets. We look forward to further applying this model to deliver high-quality pipeline assets for our partners and generate sustained value for our shareholders."

"PharmaEngine has been advancing its R&D capabilities, and our collaboration with XtalPi exemplifies our ability to harness innovative technologies to propel next-generation discoveries in precision oncology," said Dr. Hong-Ren Wang, CEO and President of PharmaEngine. "XtalPi’s R&D platform played a key role in the early-stage discovery of PEP08, providing a robust foundation for its clinical entry. Our collaboration of PEP08 and the second project demonstrates our ongoing efforts to advance cancer treatment development worldwide.

Vlad Coric, M.D., Chairman and Chief Executive Officer of Biohaven, commented, "We are planning for a transformative year ahead at Biohaven, with multiple potential value-driving milestones on the horizon. In the coming several weeks, we expect the initiation of our pivotal clinical trials to advance our novel MoDE and TRAP extracellular protein degradation platform into two pivotal studies, BHV-1300 for Graves’ disease and BHV-1400 for IgA nephropathy. These pivotal trials represent a key milestone for the degrader platform and further extends the clinical validation of our strategy to selectively degrade disease-causing proteins with our precision immunology technology. In the second half of 2026, we expect to report pivotal data from our epilepsy program and topline results from our obesity program."

Dr. Coric continued, "Additionally, our first-in-class FGFR3-directed ADC, BHV-1530, continues dose escalation with no dose-limiting toxicities observed to date, and we have begun an expansion cohort in advanced endometrial cancer with our next-generation TROP-2 directed ADC BHV-1510 in combination with Libtayo. We are also excited about progress with our TYK2/JAK1 inhibitor for early Parkinson’s disease and continue to advance enrollment in this trial. Finally, our thought leadership in neurology was on display last month at AAN, where we notably delivered a total of 5 oral presentations and posters highlighting our differentiated neuroscience and immunoscience portfolio. Though our approach has been marked by a disciplined and careful management of resources, we are pleased with progress achieved in recent months and look forward to sharing more detailed and robust updates across our portfolio at our annual R&D Day at the Yale Innovation Summit on May 27, 2026 in New Haven, Connecticut."

First Quarter 2025 Financial Highlights:

Research and Development (R&D) Expenses: R&D expenses, including non-cash share-based compensation costs, were $103.8 million for the three months ended March 31, 2026, compared to $187.6 million for the three months ended March 31, 2025. The decrease of $83.8 million was primarily due to decreases in direct program and preclinical spend, and non-cash share-based compensation expense in 2026 as compared to the same period in the prior year. The decrease in direct program spend was largely due to our strategic reprioritization of programs which was implemented in the fourth quarter of 2025. The decrease in R&D expense included a $17.0 million decrease in preclinical research programs, which was primarily due to an upfront share payment valued at $4.9 million and an accrual for an upfront cash payment of $5.0 million related to agreements entered into during the three months ended March 31, 2025.

General and Administrative (G&A) Expenses: G&A expenses, including non-cash share-based compensation costs, were $26.6 million for the three months ended March 31, 2026, compared to $34.0 million for the three months ended March 31, 2025. The decrease of $7.4 million was primarily due to decreased non-cash share-based compensation expense. Non-cash share-based compensation expense was $9.8 million for the three months ended March 31, 2026, a decrease of $8.0 million as compared to the same period in 2025. Non-cash share-based compensation expense was lower in 2026 primarily due to our annual equity incentive awards granted in the first quarter of 2026, which had a lower grant date fair value per share than the annual awards granted in the first quarter of 2025.

Other (Expense) Income, Net: Other (expense) income, net was other expense, net of $0.2 million for the three months ended March 31, 2026, compared to other income, net of $0.5 million for the three months ended March 31, 2025. The decrease of $0.3 million was primarily due to non-cash losses related to changes in fair value of our notes payable liability under the Note Purchase Agreement with Beetlejuice SA LLC, an affiliate of Oberland Capital Management LLC, entered into during the second quarter of 2025 (the NPA), and decreased investment income during the three months ended March 31, 2026, which was partially offset by losses recorded for the non-cash changes in the fair value of our forward contracts and derivative liabilities in connection with the amendment to our Membership Interest Purchase Agreement with Knopp Biosciences LLC in May 2024 (the Knopp Amendment) during the three months ended March 31, 2025.

Net Loss: Biohaven reported a net loss for the three months ended March 31, 2026 of $130.5 million, or $0.88 per share, compared to $221.7 million, or $2.17 per share, for the same period in 2025. Non-GAAP adjusted net loss for the three months ended March 31, 2026 was $102.2 million, or $0.69 per share, compared to $166.8 million, or $1.64 per share, for the same period in 2025. These non-GAAP adjusted net loss and non-GAAP adjusted net loss per share measures, more fully described below under "Non-GAAP Financial Measures," exclude non-cash share-based compensation charges and losses from the change in fair value of derivatives. A reconciliation of the GAAP financial results to non-GAAP financial results is included in the tables below.
