Clarity Pharmaceuticals: Revolutionizing Prostate Cancer Diagnostics

Key Highlights

• 64Cu-SAR-bisPSMA received its second Fast Track Designation (FTD) from the U.S. FDA, recognizing its potential to address unmet medical needs in prostate cancer diagnostics.
• The designation facilitates expedited regulatory review and development, allowing for quicker access to patients.
• Demonstrated ability to detect lesions as small as 2 mm, compared to 5 mm with current standard care (SOC) agents.
• Next-day imaging with 64Cu-SAR-bisPSMA identified nearly double the lesions detected in same-day scans.
• The bivalent structure of bisPSMA and copper-64’s longer half-life (12.7 hours) improve uptake, retention, and scheduling flexibility.
• The Phase I/II COBRA study highlighted the safety and diagnostic accuracy of 64Cu-SAR-bisPSMA in patients with biochemical recurrence (BCR).

Clarity Pharmaceuticals (ASX: CU6) has achieved a pivotal milestone in its mission to advance cancer care. The U.S. Food and Drug Administration (FDA) has granted Fast Track Designation (FTD) for 64Cu-SAR-bisPSMA, Clarity Pharmaceuticals (ASX: CU6) cutting-edge diagnostic agent for PET imaging of prostate-specific membrane antigen (PSMA)-positive prostate cancer lesions in patients with biochemical recurrence (BCR).

This designation underscores the FDA’s recognition of 64Cu-SAR-bisPSMA as a breakthrough innovation addressing a significant unmet medical need. It also highlights Clarity Pharmaceuticals (ASX: CU6) commitment to improving diagnostic precision and treatment planning for prostate cancer patients.

Second FDA Fast Track Designation

Building on the earlier FTD for patients with suspected metastasis of prostate cancer, this milestone accelerates Clarity Pharmaceuticals (ASX: CU6) comprehensive diagnostic program. The dual FTDs allow Clarity Pharmaceuticals (ASX: CU6) to expedite development and regulatory review, enabling faster access to market for 64Cu-SAR-bisPSMA.

Enhanced Diagnostic Performance

The bivalent structure of bisPSMA and the extended half-life of copper-64 (12.7 hours vs. less than 2 hours for alternatives like 18F and 68Ga) give 64Cu-SAR-bisPSMA a significant edge. These features allow for:

• Improved lesion detection: Able to detect lesions as small as 2 mm.
• Flexible imaging schedules: Next-day imaging capability unmatched by current PSMA agents.
• Broader distribution: Thanks to copper-64's longer shelf life, central manufacturing and widespread access become feasible.

COBRA Trial Success

The Phase I/II COBRA study provided compelling evidence of 64Cu-SAR-bisPSMA’s diagnostic superiority, detecting twice as many lesions as standard care agents. Notably, next-day imaging almost doubled lesion detection compared to same-day scans, cementing its potential as a best-in-class diagnostic tool.

Impact on Prostate Cancer Care

Prostate cancer remains one of the most common cancers in men globally, with an urgent need for innovative diagnostic solutions. The FTD highlights the FDA’s confidence in 64Cu-SAR-bisPSMA to redefine diagnostic standards. By offering improved accuracy and accessibility, Clarity Pharmaceuticals (ASX: CU6) technology addresses critical gaps in current-generation PSMA agents, paving the way for earlier and more effective interventions.

Next Steps for Clarity

Clarity Pharmaceuticals (ASX: CU6) pivotal AMPLIFY trial is set to begin recruitment in the coming months, involving approximately 220 participants. This Phase III diagnostic clinical trial aims to provide conclusive evidence to support FDA approval for 64Cu-SAR-bisPSMA. Simultaneously, the investigator-led Co-PSMA trial will further validate its diagnostic performance against current standard care agents.

Dr. Alan Taylor, Clarity Pharmaceuticals (ASX: CU6) Executive Chairperson, stated, “This Fast Track Designation brings us closer to introducing a game-changing diagnostic tool for prostate cancer. With a growing U.S. market expected to reach $3 billion by 2029, 64Cu-SAR-bisPSMA holds enormous potential to set a new standard in prostate cancer care.”

A Look Ahead

Clarity Pharmaceuticals (ASX: CU6) continues to lead the way in radiopharmaceutical innovation, with 64Cu-SAR-bisPSMA poised to deliver transformative benefits to patients and healthcare providers.

By addressing the limitations of current diagnostic agents and enhancing accessibility through central manufacturing, Clarity Pharmaceuticals (ASX: CU6) is positioned to make a significant impact in the fight against prostate cancer.
