The data generated from this study will provide evidence for the treatment of AAA617 in early-stage prostate cancer patients to control recurrent tumor from progressing to fatal metastatic disease while preserving quality of life by delaying treatment with androgen deprivation therapy (ADT).
NCT06499870 ↗	Relugolix and Enzalutamide in Combination With Radiation Therapy for the Treatment of Very High Risk Prostate Cancer, OPTIMAL Trial	RECRUITING	National Cancer Institute (NCI)	PHASE2	2024-09-06	This phase II trial tests how well relugolix and enzalutamide, in combination with radiation therapy, works in treating patients with very high risk prostate cancer. Relugolix is a form of androgen deprivation therapy. It prevents the release of testosterone, a hormone required to sustain prostate growth. Reducing testosterone levels may inhibit the proliferation of prostate tumor cells that need testosterone to grow. Enzalutamide is an androgen receptor signaling inhibitor. It inhibits the activity of prostate tumor cell receptors, which may reduce proliferation of prostate tumor cells. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Adding relugolix and enzalutamide to radiation therapy may be more effective at treating patients with very high risk prostate cancer than giving any of these treatments alone.

Clinical Trials Update, Market Analysis, and Projection for Piflufolastat F-18

Last updated: October 30, 2025

Introduction

Piflufolastat F-18 (also known by its research development name, PyL) is a novel PET imaging agent specifically designed for prostate cancer detection and management. As a radiotracer that binds to prostate-specific membrane antigen (PSMA), it offers high sensitivity and specificity for detecting prostate cancer metastases, particularly in cases of biochemical recurrence. The recent landscape of clinical trials, regulatory progress, market dynamics, and future projections for Piflufolastat F-18 form a compelling narrative regarding its potential to revolutionize prostate cancer imaging.

Clinical Trials Landscape

Key Clinical Trials and Outcomes

Piflufolastat F-18’s clinical development has been marked by pivotal trials demonstrating its efficacy and safety. The most notable study, ACRIN 6684, was a multicenter phase II trial published in 2020, which revealed high detection rates of prostate cancer lesions in patients with biochemical recurrence, with a sensitivity surpassing other conventional imaging methods [1].

Furthermore, the Ongoing Phase III trials aim to compare Piflufolastat F-18 PET imaging directly against established standards such as conventional CT, MRI, or other PSMA-based agents. The study NCT04186855, sponsored by Lantheus Medical Imaging, assessed its diagnostic performance in men with prostate cancer across multiple institutions, indicating promising results to support regulatory review.

Regulatory Progress

In December 2021, the U.S. Food and Drug Administration (FDA) approved Piflufolastat F-18 under the New Drug Application (NDA) process, minimizing barriers for commercial deployment. Additionally, Piflufolastat F-18 has received Orphan Drug Designation in some regions, further encouraging development and facilitating faster reviews.

Clinical Challenges

Despite promising data, ongoing trials are scrutinizing the agent’s performance in various clinical contexts:

• Differentiation between benign and malignant PSMA expression.
• Utility in initial staging versus recurrent settings.
• Long-term safety, especially related to radioactivity exposure.

Results from these trials will determine its broad clinical adoption scope and label expansion possibilities.

Market Analysis

Market Size and Growth Drivers

Prostate cancer remains the second most common cancer worldwide, with an estimated 1.4 million new cases in 2020 alone. The global prostate cancer imaging market is projected to grow at a CAGR exceeding 8% through 2027 [2]. Key drivers include:

• Increasing incidence and aging populations.
• Demand for precise, minimally invasive diagnostic modalities.
• Limitations of current imaging techniques like CT, MRI, and bone scans.

The introduction of advanced PSMA-targeted imaging agents such as Piflufolastat F-18 is poised to capture significant market share, owing to its superior diagnostic accuracy.

Competitive Landscape

Unlike its predecessor, Gallium-68 PSMA-11 (Ga-68 PSMA), Piflufolastat F-18 benefits from the broader distribution network inherent to F-18 radiotracers, due to the longer half-life (~110 minutes) and established production and logistics infrastructure. Its main competitors include:

• Ga-68 PSMA-11 (approved in some regions).
• Fluorine-18-based agents like F-18 DCFPyL (Lantheus), which is already marketed in the U.S.

Piflufolastat F-18 is differentiated by higher image resolution, logistical advantages, and better scalability.

Market Penetration and Adoption Factors

Factors accelerating market entry include:

• Positive clinical trial outcomes.
• Regulatory approvals.
• Expansion of production capacity.
