Radiopharm banks $5.9M R&D tax refund to fuel oncology pipeline

Radiopharm Theranostics (ASX: RAD, Nasdaq: RADX) has received its research and development (R&D) tax refund for the 2025 financial year, totalling A$5,885,131. The clinical-stage biopharmaceutical company will direct the funds towards continued development of its portfolio of radiopharmaceutical products for diagnostic and therapeutic applications.

The refund, which included A$104,475 in interest, was received under the Australian Government’s R&D Tax Incentive. That scheme provides eligible companies with a refundable tax offset of up to 43.5% on qualifying research activity.

What the refund means for Radiopharm’s funding position

The funds are earmarked for continued development of the product portfolio across both diagnostic and therapeutic applications. No cash balance, runway figure, or burn rate was disclosed in the announcement.

Board Authorisation

The announcement was authorised on behalf of the Radiopharm Theranostics Board of Directors by Executive Chairman Paul Hopper.

How the R&D Tax Incentive works (and why it matters to biotech investors)

The Australian Government’s R&D Tax Incentive allows eligible companies conducting qualifying research to claim a refundable tax offset of up to 43.5%. In practice, a portion of what a company spends on R&D can be returned as a cash refund.

Inside Radiopharm’s clinical pipeline

The refund ultimately supports Radiopharm’s radiopharmaceutical platform. The company develops radiopharmaceutical products for diagnostic and therapeutic use in cancers of high unmet medical need.

Its pipeline spans distinct and highly differentiated platform technologies, including peptides, small molecules, and monoclonal antibodies. The clinical program comprises one Phase 2 and five Phase 1 trials across a range of solid tumour cancers.

The RAD101 Phase 2b program is among the most advanced assets the refund supports, with interim data showing 90% concordance with MRI in brain metastases patients and a Siemens Healthineers supply agreement already in place for the planned Phase 3 registrational trial.
