FDA Approves Phase III Trial, Offering New Hope for Advanced Prostate Cancer Patients
Key Takeaways
- The FDA has approved Laekna's Phase III trial protocol for a new combination therapy for advanced prostate cancer.
- The Phase II trial showed significant improvement in progression-free survival for mCRPC patients.
- The combination therapy is generally well-tolerated with manageable side effects.

Introduction to Prostate Cancer and mCRPC
Prostate cancer is a significant health concern, particularly in aging men. When the disease progresses to metastatic castration-resistant prostate cancer (mCRPC), it becomes more challenging to treat, often resisting standard therapies.
Laekna, Inc., a clinical-stage biotechnology company, has recently announced a significant milestone that could offer new hope for patients with mCRPC.
FDA Approval for Phase III Trial
The U.S. Food and Drug Administration (FDA) has approved the protocol for Laekna's Phase III clinical trial combining two novel drugs, LAE002 (afuresertib) and LAE001, to treat patients with mCRPC who have not responded adequately to standard care.
This approval follows promising results from a Phase II trial, demonstrating the efficacy and safety of this drug combination.
Details of the Phase II Study
The Phase II study began in the United States in June 2021 and expanded to South Korea in September 2022. This open-label study tested different doses to find the most effective and safest combination for patients. Promising results showed a significant improvement in patients' progression-free survival compared to traditional treatments.
Specifically, patients who had experienced progression on one to three lines of standard treatments, including therapies like abiraterone, saw a median progression-free survival (rPFS) of 8.1 months with the new treatment, a notable increase over the historical 2 to 4 months under standard care.
Safety and Tolerability
One of the key findings from the Phase II trial was the tolerability of the combination therapy. Most adverse effects were manageable and resolved with standard treatments, making this an appealing option for patients who have limited alternatives.
The Role of Afuresertib (LAE002)
Afuresertib is an AKT inhibitor that has shown considerable promise in treating various cancers. Its ability to inhibit multiple AKT isoforms makes it potentially more effective and safer than other inhibitors.
This drug has not only shown benefits in prostate cancer but also in other cancers such as breast and ovarian, which speaks to its broad potential.
The Role of LAE001
LAE001 is a dual inhibitor targeting CYP17A1 and CYP11B2, enzymes involved in androgen and aldosterone synthesis. This characteristic allows LAE001 to work without the need for prednisone, which can cause several adverse effects over time.
By effectively blocking these pathways, LAE001 offers a new approach to controlling hormone-driven prostate cancers.
Significance of the FDA Approval
Receiving FDA approval for the Phase III trial marks a pivotal moment for Laekna. This approval is a testament to the hard work and promising results demonstrated in earlier trials and sets the stage for potentially bringing a groundbreaking treatment to patients in need.
Dr. Yong Yue, Chief Medical Officer of Laekna, highlighted the global unmet need for effective mCRPC treatments and expressed optimism about the new therapy's potential to improve patient outcomes.
Future Directions and Ongoing Research
Laekna is committed to advancing its clinical trials across multiple regions and cancer types. The company's pipeline includes ongoing studies for breast, ovarian, and other solid tumors resistant to current therapies.
These efforts illustrate Laekna's dedication to addressing critical gaps in cancer treatment and improving the overall quality of life for patients worldwide.
Conclusion
With the FDA's recent approval, LAE002 and LAE001 are moving closer to potentially being available as a new treatment option for patients battling advanced prostate cancer. This development underscores the importance of continuous innovation and rigorous clinical testing in finding effective solutions for difficult-to-treat cancers.
Patients and healthcare providers alike are looking forward to the results of the Phase III trial and the positive impact it may have on future cancer treatments.
