The Company’s cash and cash equivalents totalled $30.7 million at the end of the quarter, with 80% of spending ($2.46m) directed toward research and development (R&D) and drug manufacturing activities. A strong cash balance places Racura in an excellent position to fund all committed activities into mid-CY2028. During the quarter, Racura continued to make significant progress across its clinical programs. In July, Racura expanded the HARNESS -1 lung cancer trial through additional ethics approvals, enabling the activation of new Australian clinical trial sites, and reported positive initial safety data from the first patient treated with RC220 in combination with osimertinib. The Company also received international recognition for its Cardioprotection and Anticancer Synergy (CPACS) program through acceptance for presentation at the Global Cardio -Oncology Summit. In September, Racura expanded the global footprint of the CPACS trial through the activation of clinical trial sites in South Korea, while new preclinical data further validating the ability of RC220 to inhibit MYC gene transcription were accepted for presentation at the Frontiers in Cancer Science Conference in Singapore. Management commentary Chief Executive Officer and Managing Director Dr Daniel Tillett commented: “We have made solid progress with our clinical programs with both the Phase 1 HARNESS -1 and CPACS trials clearing their first dose cohorts without any dose-limiting toxicities. With the expansion of CPACS into South Korea and $30.7 million in cash, Racura is well funded to continue advancing RC220 into mid-CY2028.”

On 9 July 2026, Racura announced that its CPACS Phase 1 trial had been selected for presentation at the 2026 Global Cardio-Oncology Summit in the United States. The presentation will provide an update on the ongoing evaluation of RC220 in combination with doxorubicin in patients with advanced solid tumours and highlight growing international interest in the program ’s potential cardioprotective and anticancer benefits. On 29 July 2026, Racura announced that the first patient treated with RC220 and osimertinib in the HARNESS-1 trial had completed safety review with no dose -limiting toxicities or treatment - related safety concerns identified during the safety observation pe riod.

On 8 September 2026, Racura announced that new preclinical data supporting the G4 -binding mechanism of action of (E,E)-bisantrene and inhibition of MYC gene transcription had been accepted for presentation at the 2026 Frontiers in Cancer Science Conference in Singapore.

The Company’s lead asset, (E,E)-bisantrene, is a small-molecule anticancer agent that binds G4-DNA and RNA structures and potently inhibits MYC gene expression, a key cancer target dysregulated in up to 70% of cancers. Bisantrene has a long history of demonstrated therapeutic activity in cancer patients with a well-characterised safety profile. Recent discoveries have supported composition-of-matter and other patent filings that, if granted, could provide up to 20 years of protection for (E,E)-bisantrene. Racura is advancing a proprietary formulation of (E,E) -bisantrene (RC220) to address the high unmet needs of patients across multiple oncology indications, with a Phase 2b/3 pivotal clinical program in acute myeloid leukaemia (AML), a Phase 1a/b program in mutant epidermal growth factor receptor non -small cell lung cancer (EGFRm NSCLC), and a Phase 1a/b program in combination with the anthracycline doxorubicin, where we aim to deliver both cardioprotection and enhanced anticancer activity for patients with solid tumours. Racura has collaborated with Astex, Emory University, Purdue University, MD Anderson, Sheba City of Health, UNC School of Medicine, University of Wollongong, and University of Newcastle. Racura is actively exploring partnerships, licence agreements, or a commercial merger and acquisition to accelerate access to RC220 for patients with cancer across the world.
