About PSTV
Plus Therapeutics, Inc. is a clinical-stage pharmaceutical company. The Company is engaged in developing targeted radiotherapeutics for difficult-to-treat cancers of the central nervous system. Combining image-guided local beta radiation and targeted drug delivery approaches, it is advancing a pipeline of product candidates with lead programs in leptomeningeal metastases (LM) and recurrent glioblastoma (GBM). Its lead radiotherapeutic candidate, REYOBIQ (rhenium (186Re) obisbemeda), is designed specifically for CNS cancers including GBM, LM, and pediatric brain cancers (PBC) by direct localized delivery utilizing approved standard-of-care tissue access such as with convection-enhanced delivery (CED) and intraventricular brain (Ommaya reservoir) catheters. Its radiotherapeutic candidate, Rhenium-188 NanoLiposome Biodegradable Alginate Microsphere (188RNL-BAM), is designed to treat many solid organ cancers including primary and secondary liver cancers via intra-arterial injections.

Plus Therapeutics Presents REYOBIQ Clinical Data at AANS Annual Meeting
- Clinical Data Highlights: At the 2026 AANS Annual Meeting, Plus Therapeutics presented data from the Phase 1 ReSPECT-LM trial of REYOBIQ, showing a median overall survival of approximately 9 months at the recommended Phase 2 dose, significantly better than the historical range of 2-6 months, indicating the therapy's potential for patients with leptomeningeal metastases lacking FDA-approved treatments.
- Anti-Tumor Activity: The study demonstrated robust anti-tumor activity, including significant reductions in circulating tumor cells (CTC) and clinical benefits, supporting the advancement of REYOBIQ into later-stage clinical development and potentially offering new treatment options for patients.
- Safety and Tolerability: REYOBIQ exhibited a favorable safety and tolerability profile, which supports its progression into later-stage clinical trials, with a target-to-off-target absorbed dose ratio exceeding 100:1, minimizing exposure to healthy tissue.
- Immune Remodeling Potential: Translational analyses indicated that REYOBIQ may induce immune remodeling within the tumor microenvironment, including activation of CD8+ T cells and enhancement of anti-tumor immune responses, supporting potential future combination strategies with immunotherapies.

Plus Therapeutics Secures Medicare Enrollment for CNSide Diagnostics
- Successful Medicare Enrollment: Plus Therapeutics' wholly owned subsidiary, CNSide Diagnostics, has successfully enrolled in Medicare and received a Provider Transaction Access Number (PTAN), marking a critical step in its commercialization strategy for the CNSide® Cerebrospinal Fluid assay platform, which is expected to significantly enhance the company's revenue potential in the U.S. market.
- Expanded Coverage: The Medicare enrollment allows CNSide Diagnostics to serve approximately half of the U.S. Medicare population, which not only improves patient access to testing but also paves the way for future entry into Medicare Advantage plans, thereby strengthening the company's competitive position in the market.
- Accelerated Pricing and Coverage Efforts: With enrollment secured, CNSide Diagnostics will actively engage with local Medicare Administrative Contractors (MACs) to pursue local coverage determinations (LCDs) and support pricing decisions under the Clinical Laboratory Fee Schedule (CLFS), optimizing revenue capture.
- Commercial Expansion Plans: The company aims to further broaden its coverage through national and regional payer contracts, targeting over 150 million covered lives by 2026, which will lay a solid foundation for future growth.

CNSide Diagnostics Secures Coverage Agreement with Blue Shield of California
- Expanded Coverage: CNSide Diagnostics' new payer coverage agreement with Blue Shield of California increases the total covered lives for its CNSide® CSF Tumor Cell Enumeration assay from 75 million to 81 million, making significant progress towards the company's goal of 150 million covered lives by 2026, thereby enhancing patient access across the U.S.
- Accelerated Adoption: The agreement is expected to further accelerate the adoption of CNSide across oncology centers by reducing reimbursement barriers, enabling physicians to better diagnose and treat difficult-to-diagnose CNS cancers, which will ultimately improve patient outcomes.
- Enhanced Clinical Utility: The CNSide® assay platform has demonstrated superior clinical utility over conventional CSF cytology in nine peer-reviewed publications and the FORESEE clinical trial, enabling earlier and more accurate detection and monitoring of leptomeningeal metastases, which has been shown to reduce related healthcare costs by approximately 40%.
- Market Impact: Since its commercial launch in 2020, over 11,000 CNSide tests have been performed at more than 120 U.S. cancer institutions, achieving a sensitivity of 92% and specificity of 95%, influencing treatment decisions in 90% of cases, thereby solidifying its market position.
