Clarity Reports $95M Cash, Prioritizes Prostate Cancer Asset Amid Clinical Progress

Financial Strength and Strategic Refocus

Clarity Pharmaceuticals closed the March 2025 quarter with a strong cash balance of $95.1 million, further bolstered by an $11.1 million receipt in April from the FY24 research and development tax incentive. This combined funding of approximately $106 million is expected to sustain operations through the second half of 2026, providing a solid runway amid ongoing market volatility.

In response to external financial market pressures and a strategic portfolio review, Clarity has streamlined its clinical programs to focus on high-priority assets. The company has elected to concentrate resources on its lead product, Cu-SAR-bisPSMA, targeting both diagnostic and therapeutic applications in prostate cancer. This decision involved the closure of two theranostic trials, CL04 and COMBAT, without safety concerns but reflecting a prudent allocation of capital towards programs with higher commercial potential and earlier market entry.

Clinical Progress and Regulatory Milestones

Cu-SAR-bisPSMA continues to demonstrate compelling clinical promise. The SECuRE Phase I/IIa theranostic trial recently completed its Dose Escalation Phase, with the Safety Review Committee endorsing progression to the Cohort Expansion Phase at an 8 GBq dose level and increasing treatment cycles from four to six. Early data highlight significant prostate-specific antigen (PSA) reductions, particularly in pre-chemotherapy metastatic castration-resistant prostate cancer (mCRPC) patients, with 92% showing PSA drops greater than 35% and nearly half achieving reductions of 80% or more.

Complementing therapeutic development, Clarity is advancing two Phase III diagnostic trials, CLARIFY and AMPLIFY, evaluating Cu-SAR-bisPSMA PET imaging in high-risk and biochemical recurrence prostate cancer populations, respectively. Additionally, the investigator-initiated Co-PSMA trial is underway, comparing Cu-SAR-bisPSMA to the current standard of care Ga-PSMA-11 imaging.

Regulatory momentum is underscored by three FDA Fast Track Designations (FTDs) granted for SAR-bisPSMA: one therapeutic and two diagnostic indications. These designations facilitate expedited development and review, positioning Clarity to potentially disrupt a prostate cancer market valued well over US$10 billion.

Pipeline Expansion and Supply Chain Enhancements

Beyond prostate cancer, Clarity is expanding its pipeline with SAR-trastuzumab, a novel theranostic targeting HER2-positive breast cancer, supported by promising preclinical data. The company plans a Phase I/IIa clinical study to address this aggressive cancer subtype with significant unmet needs.

Recognizing the critical importance of isotope supply for commercialisation, Clarity has secured two key supply agreements for copper-64. In the US, a commercial-scale partnership with Nusano, Inc. will enable mass production from a state-of-the-art Utah facility, capable of delivering over 18,000 patient doses daily with a 48-hour shelf life. In Australia, an agreement with the University of Queensland’s Centre for Advanced Imaging will support ongoing clinical trials and preclinical programs, reinforcing Clarity’s commitment to domestic manufacturing and scientific collaboration.

Operational Efficiency and Outlook

Operating cash outflows for the quarter were $15.3 million, a reduction from the prior quarter, reflecting timing of clinical trial payments. The company reports no material variances against its previously disclosed use of funds, maintaining disciplined financial management as it advances toward commercial milestones.

Clarity’s Executive Chairperson, Dr Alan Taylor, emphasized the company’s focus on leveraging strong clinical data and regulatory designations to accelerate the path to market, while navigating external market challenges with strategic program adjustments and robust supply chain initiatives.
