About PLUS THERAPEUTICS, INC.

http://www.plustherapeutics.com/

Plus Therapeutics is a clinical-stage pharmaceutical company focused on developing targeted radiotherapeutics for difficult-to-treat cancers in adults and children. The company's technology platform is designed to deliver high-dose, localized radiation directly to tumors. Its core approach involves encapsulating Rhenium radioisotopes (186Re and 188Re) within nanoliposomes. The lead investigational drug, REYOBIQ™ (rhenium Re186 obisbemeda), is a nanoliposome therapy targeting brain and central nervous system (CNS) cancers, including recurrent glioblastoma and leptomeningeal metastases. A second pipeline program, Rhenium-188 NanoLiposome Biodegradable Alginate Microsphere (188RNL-BAM), is a radioembolization therapy being developed for solid organ cancers, such as liver cancer. The use of Rhenium allows for both therapeutic beta radiation and gamma imaging during treatment.

Filing Released Lang Actions
8-K
Capital/Financing Update Classification · 90% confidence The document is a Form 8-K Current Report disclosing the entry into an Equity Distribution Agreement to sell up to $17.35 million of common stock. This constitutes a financing activity—a planned at-the-market equity offering—and therefore falls under Capital/Financing Update (CAP).
2026-06-05 English
S-3/A
Regulatory Filings Classification · 85% confidence The document is a pre-effective amendment (No. 1) to a Form S-3 registration statement filed with the SEC, consisting primarily of exhibits, certifications, and legal disclosures under the Securities Act. It is not a financial report (e.g., 10-K, 10-Q), nor an earnings release, management discussion, proxy, or dividend notice. It is a compliance/regulatory submission to register securities rather than an announcement of specific capital issuance details or meeting results. Therefore it falls under general regulatory filings (RNS).
2026-06-05 English
S-3
Capital/Financing Update Classification · 90% confidence The document is an SEC registration statement on Form S-3 for a shelf offering of up to $100 million of various securities (common stock, preferred stock, warrants, debt securities, subscription rights, and units). This is not an Annual or Interim Report, nor a proxy, nor a management or audit report. Instead, it is a financing document related to the company’s planned capital raise and issuance of new securities. Under the classification definitions, this falls under “Capital/Financing Update” (CAP) which covers updates on company fundraising, financing activities, or capital structure changes.
2026-06-01 English
8-K
Declaration of Voting Results & Voting Rights Announcements Classification · 90% confidence The document is a Form 8-K filed under Section 5.07 (“Submission of Matters to a Vote of Security Holders”) reporting detailed vote results at the company’s 2026 Annual Meeting. It provides official voting tallies for director election, ratification of auditors, advisory compensation vote, and amendment to the stock incentive plan. This matches the definition for “Declaration of Voting Results & Voting Rights Announcements,” not a full report or proxy statement itself.

10-Q
Interim / Quarterly Report Q1 2026
2026-05-15 English
8-K
Regulatory Filings Classification · 86% confidence The document is a Form 8-K “Current Report” filed with the SEC (notice of Item 2.02 Results of Operations and Financial Condition), without the actual earnings content but referencing the press release as Exhibit 99.1. This is a regulatory filing and does not itself contain the full earnings release or financial statements, so it falls under the general Regulatory Filings category (fallback).
