Plus Therapeutics Reports First Quarter 2021 Financial Results and Business HighlightsManagement to host conference call today at 5:00 pm ET

AUSTIN, Texas, April 22, 2021 (GLOBE NEWSWIRE) -- Plus Therapeutics, Inc. (Nasdaq: PSTV) (the “Company”), a clinical-stage pharmaceutical company developing novel, targeted therapies for rare and difficult to treat cancers, today announced financial results for the first quarter ended March 31, 2021, and provided an overview of recent business highlights.

The Company’s lead investigational drug is Rhenium NanoLiposome (RNL™), a radiotherapy in development for several rare cancer targets, including recurrent glioblastoma (GBM). RNL™, currently being evaluated in the U.S. multi-center ReSPECT™ Phase 1 dose-finding clinical trial, is designed to safely, effectively, and conveniently deliver a very high dose of radiation directly to brain tumors.

“In the first quarter of 2021, we made meaningful progress in critical areas including advancing our drug development and manufacturing activities, refining our clinical understanding of RNL™ behavior in the glioblastoma patients and in seeking FDA feedback on potential new clinical indications for RNL™,” said Marc H. Hedrick M.D., President and Chief Executive Officer of Plus Therapeutics.

First Quarter 2021 Clinical Highlights

Company highlights during the first quarter of 2021 included:

  • Entering into a master services agreement (MSA) with Piramal Pharma Solutions for the development, manufacture, and supply of RNL™ intermediate drug product.
  • Completing the 6th dose escalation cohort, with 18 patients treated in ReSPECT™, with concomitant increases in both RNL™ drug volume and radiation dose.
  • Beginning treatment in an expansion cohort at the 6th dose with higher drug flow rates and faster drug infusion times.
  • Submitting 2 RNL™ pre-IND meeting briefing packages to the U.S. Food and Drug Administration (FDA) for treatment of leptomeningeal metastases and pediatric brain cancers, specifically ependymoma, high-grade glioma, and diffuse intrinsic pontine glioma.

Expected Upcoming Clinical Milestones and Events for 2021

In upcoming quarters in 2021, the Company intends to focus on a number of additional business objectives and potential milestones:

  • Complete enrollment of the ReSPECT™ Phase 1 trial for RNL™ in recurrent glioblastoma.
  • Complete pivotal trial planning in conjunction with FDA feedback for RNL™ in recurrent glioblastoma.
  • Complete a pre-IND meeting with the FDA, execute IND-enabling studies, if needed, and move into clinical trials for new RNL™ indications.
  • Continue development and evaluation of additional external and internal drug development candidates to expand the drug development pipeline.
  • Continue to explore partnership opportunities for three clinical-stage investigational drugs: RNL™, DocePLUS™ and generic DoxoPLUS™.

First Quarter 2021 Financial Results

  • As of March 31, 2021, the Company’s cash balance was $14.4 million, compared to $8.3 million as of December 31, 2020.
  • Total operating expenses for the first quarter of 2021 was $2.5 million, compared to total operating expenses of $2.56 million for the same quarter in 2020.
  • Net loss for the first quarter of 2021 was $2.7 million, or $(0.33) per share, compared to a net loss of $1.1 million, or $(0.28) per share, for the same quarter in 2020. The net loss was consistent year on year when excluding the book gains on the warrants reported in Q1 2020. Remeasurement of warrant liabilities was no longer required for Series U warrants that were amended in Q2 and Q3 2020 and reclassified to equity.
