Rakovina Therapeutics Inc. (RKV:TSX.V) increased the share of its budget focused on AI-powered drug discovery to 72% in the second quarter of 2026, up from 57% in the same period of 2025, as the company continued advancing three AI-supported cancer drug programs.
The shift came as general and administrative expenses declined approximately 63% year over year to CA$450,695 from CA$1.21 million. Research and development expenses totaled CA$1.13 million during the quarter, while R&D spending for the first six months of 2026 reached CA$2.16 million, compared with CA$1.61 million in the same period of 2025. The company attributed the change to lower contract research and consulting costs, partially offset by increased chemistry and AI research activity.
"In Q2 2026, we reduced G&A by more than 60% year-over-year for a second consecutive quarter, such that 72% of our budget was focused on AI-powered drug discovery compared to 57% in Q2 2025," Chief Executive Officer Kim Oishi said in the company's news release. "Our focus for the balance of 2026 is advancing our three AI-powered drug discovery programs, enhancing relationships with our AI collaborators, and securing non-dilutive financing from industry and government sources."
Rakovina also reduced its quarterly net loss by approximately 41%, reporting a loss of CA$1.73 million for the three months ended June 30, compared with CA$2.92 million in the second quarter of 2025.
Following the end of the quarter, the company completed an upsized non-brokered private placement for aggregate gross proceeds of CA$1.99 million, subject to final acceptance by the TSX Venture Exchange. The first tranche closed August 12 for CA$1.39 million, after Rakovina increased the maximum offering from CA$1.5 million to CA$2 million.
As of June 30, Rakovina had CA$200,115 in cash and cash equivalents and a working capital deficit of CA$2.13 million, compared with CA$298,758 and a CA$2.15 million working capital deficit, respectively, at December 31, 2025.
The company also highlighted preclinical research presented at the American Association for Cancer Research Annual Meeting on April 22. Data from its kt-5000 series, a dual ATR-mTOR inhibitor program, demonstrated anti-tumor activity, selectivity, measurable central nervous system penetration, and tumor growth inhibition with improved tolerability relative to reference ATR inhibitors. Rakovina also presented initial formulation data for kt-3283, its dual PARP/HDAC inhibitor, demonstrating successful development of a lipid nanoparticle formulation.
At its August 19 annual general meeting, shareholders elected five directors and re-appointed Davidson & Company LLP as auditor. Dr. Petra Hamerlik joined the board, while Jeffrey Bacha retired as a director and continued in an advisory capacity.
AI Drug Programs Move Toward Lead Selection and Preclinical Studies
Rakovina Therapeutics' Q2 investor presentation laid out a series of 2026 and first-half 2027 milestones for its three AI-supported cancer drug programs. The presentation identified Rakovina as developing DNA Damage Response cancer therapies using AI platforms alongside laboratory validation at UBC and the Vancouver Prostate Centre.
Rakovina's kt-5000AI program is described as a dual ATR/mTOR inhibitor designed for CNS penetration and aimed at solid tumors, PTEN-deficient cancers, and CNS metastases. The presentation states that 138 molecules had been predicted and 43 synthesized, with leads confirmed as potent and selective. CNS penetration and tolerability had also been confirmed in vivo. Its stated 2026 milestones include in vivo model data at peer-reviewed meetings, lead-optimization results from an expanded AI collaboration, lead selection, and ongoing partner discussions.
The broader development schedule calls for kt-5000AI in vivo ADME and efficacy work and progress toward lead candidate selection during the third quarter of 2026. Lead selection is scheduled for the fourth quarter, followed by GLP toxicology and IND-enabling studies in the first half of 2027.
Rakovina's kt-3000 program targets PARP-resistant adult and childhood cancers, including Ewing sarcoma. The presentation states that the program's kt-3283 compound demonstrated superior cytotoxicity compared with FDA-approved olaparib and vorinostat, and was published in Clinical Cancer Research. Rakovina is working with NanoPalm on a proposed joint venture that would combine Rakovina's AI drug discovery capabilities with NanoPalm's self-targeting patterned lipid nanoparticle delivery system, with intellectual property arising from the collaboration to be jointly owned, while background IP and technology improvements remain with their respective inventors. The presentation lists 2026 milestones of securing joint venture funding, an ADC partnership, and nano-lipid formulation data at peer-reviewed meetings.
The development schedule calls for continued in vivo studies for the PARP/HDAC program during the third quarter of 2026 and GLP toxicology and IND-enabling studies during the first half of 2027. The presentation also describes further development of pLNP-kt-3283 through in vitro and in vivo characterization to confirm activity against PARP and HDAC enzymes, determine ADME properties, and determine efficacy against in vivo tumor models.
The third program, kt-2000AI, is a brain-penetrant PARP inhibitor targeting breast, ovarian, and prostate cancers. Rakovina said billions of compounds were screened through its Deep Docking platform, with 389 compounds assessed against PARP and leads confirmed with PARP selectivity and drug-like properties.
For kt-2000AI, the schedule calls for another round of AI output and advancing lead candidate selection in the fourth quarter of 2026, followed by PARP program lead selection in the first half of 2027. Corporate milestones in the presentation include finalizing a Saudi joint venture in the third quarter, seeking institutional funding, and attending the SNO, AACR-NCI-EORTC, and BIO Middle East conferences in the fourth quarter, followed by development of strategic pharmaceutical partnerships in the first half of 2027.
The broader biotechnology sector entered 2026 with a cautiously positive outlook despite continued financing and economic pressures. A June report from EY said biotech had recorded a third consecutive year of growth, with industry revenue increasing more than 12%, while financing reached US$68.5 billion in 2025, up 11% from the previous year. EY Americas Life Sciences Leader Arda Ural described the outlook as "rather positive," while the report identified AI-driven R&D as one of the areas positioned to contribute to continued innovation.
DNA Damage Response Research Expands Beyond First-Generation Inhibitors
A February 24 review published in Oncol Res described DNA damage response, or DDR, as a central factor in tumor survival, genomic stability, and therapy resistance. The authors wrote that "PARP inhibitors have established the DDR as a therapeutic target," while noting that some tumors had evaded first-generation drugs through adaptive repair pathways and constraints within the tumor microenvironment.
The review examined next-generation approaches involving PARP, ATR, ATM, CHK1, WEE1, and DNA-PK pathways, including inhibitors designed to increase selectivity and address resistance. It also examined nanocarrier-based delivery approaches intended to improve pharmacokinetics, target resistant tumor niches, and expand combinations with immunotherapy and radiotherapy. The authors concluded that the findings provided "a guide to the implementation of next-generation DDR inhibitors and nanomedicines to deliver a more accurate, durable, and context-specific cancer therapy."
According to a research topic published by Frontiers on August 16, DDR had served as "a critical cellular network that safeguards genomic stability by detecting and repairing DNA lesions." The publication described DDR's role in cancer as a "double-edged sword," because disruption of the system could contribute to genomic instability while adaptation of DDR mechanisms in cancer cells could contribute to resistance to DNA-damaging therapies.
Frontiers also identified therapeutic vulnerabilities created by defects in particular DDR pathways. It said targeted approaches, including PARP inhibitors, had "successfully exploited this weakness," while inhibitors targeting DDR-related proteins, including ATM, ATR, CHK1, CHK2, and WEE1, had emerged as areas of continued research. The research topic focused on DDR mechanisms in tumorigenesis, resistance to DDR-targeted therapies, development and optimization of small-molecule inhibitors, and DDR-associated biomarkers for cancer detection and personalized treatment.
