HOUSTON, Dec. 09, 2025 (GLOBE NEWSWIRE) -- Plus Therapeutics, Inc. (Nasdaq: PSTV ) (“Plus” or the “Company”), a clinical-stage pharmaceutical company developing targeted radiotherapeutics with advanced platform technologies for central nervous system (CNS) cancers, today announced two new hires to its team for CNSide Diagnostics, LLC, its wholly-owned subsidiary.

“We are strategically building the team to bolster our capabilities as we scale up our laboratory operations to address the largely untapped $6billion+ U.S. addressable market for CNSide cerebrospinal fluid assay for metastatic CNS cancers, all the while maintaining the highest quality standards,” said Russ Bradley, CNSide Diagnostics, LLC President and General Manager. “We continue our steady progress toward national launch and test coverage expansion, with plans for additional payor agreements to the previously announced agreements with UnitedHealthcare and Humana .”

Two team members joining the CNSide Diagnostics team are:

  • Mr. Prem Gurnani joins as Senior Director of Lab Operations and Systems Implementation, with over sixteen years of experience in diagnostics, clinical operations, regulatory compliance, and technology driven process improvement across high growth healthcare organizations and laboratory environments, with a strong record supporting operational scale up
  • Ms. Elaine Luckey joins as Director of Quality and Regulatory affairs, with over twenty years of experience in quality and regulatory affairs in CLIA/CAP laboratory environments, with track record in start-ups, quality system implementation and regulatory compliance.

In connection with these two new hires, on December 4, 2025, the Company granted stock options and restricted stock units (“RSUs”) to Mr. Gurnani and Ms. Luckey under its 2015 New Employee Incentive Plan, which is intended to meet the requirements of a plan providing for inducement grants under Nasdaq Listing Rule 5635(c)(4). The awards were approved by the Company’s Compensation Committee and made as a material inducement to each employee's entry into employment with the Company.

The approved option awards for each of Mr. Gurnani and Ms. Luckey consist of options to purchase up to 33,750 shares of the common stock of the Company. The exercise price of the options is equal to the closing price of the Company’s common stock on December 4, 2025, the grant date. The approved option awards to Mr. Gurnani and Ms. Luckey are scheduled to vest over four years, with one-fourth of the options vesting on the first anniversary of the grant date with the remaining options vesting thereafter in 36 equal monthly installments. The vesting of the options is also subject to certain requirements, including each employee’s continued service as an employee of the Company through the applicable vesting dates.

In addition, the Company issued Mr. Gurnani and Ms. Luckey 11,250 RSUs each. The RSUs are scheduled to vest over three years, with one-third of the RSUs vesting on January 1, 2027 (approximately one-year from the first anniversary of the grant date) with the remaining RSUs vesting quarterly thereafter in eight (8) equal installments. The vesting of the RSUs is also subject to certain requirements, including continued service as an employee of the Company through the applicable vesting dates.

The Company believes that these equity grants create a strong alignment of interests between Mr. Gurnani, Ms. Luckey, and the Company’s shareholders. The equity awards were granted outside of the Company’s 2020 Incentive Plan but generally have terms and conditions consistent with those set forth in that plan. The Company has filed a Form S-8 covering these equity awards.
