CMS granting TPT status for Gozellix significantly improves reimbursement pathway and patient access, boosting Telix’s commercial prospects.
The Centers for Medicare & Medicaid Services (CMS) granting Transitional Pass-Through (TPT) payment status for Telix’s Gozellix® represents a significant regulatory and commercial milestone. This designation enables separate reimbursement under the Hospital Outpatient Prospective Payment System effective October 1, 2025, which addresses one of the most critical barriers to adoption of advanced diagnostic agents.
The TPT status provides three key financial benefits: 1) separate payment outside of bundled hospital reimbursement, 2) elimination of the 20% patient coinsurance, and 3) assignment of a permanent HCPCS Level II code (A9616) for recognition by CMS and commercial insurers. This trifecta of reimbursement advantages creates a clear payment pathway that will likely accelerate provider adoption.
For context, radiopharmaceutical reimbursement has historically been a major hurdle in nuclear medicine, with many advanced agents struggling to gain market traction despite FDA approval due to inadequate payment structures. The TPT status effectively removes this barrier for Gozellix®, positioning it for broader utilization across the US healthcare system.
From a market perspective, having a reimbursed product with a 6-hour shelf life compared to competing agents with more restrictive logistics requirements gives Telix a significant competitive advantage. The flexibility in production methods (both generator and cyclotron-based) further enhances the product’s market potential by making it accessible to various types of imaging facilities with different infrastructure capabilities.
The technical specifications of Gozellix® represent meaningful advancements in PSMA-PET imaging accessibility. The extended shelf life of up to six hours addresses one of the primary logistical challenges in nuclear medicine – the limited useful life of radiopharmaceuticals after preparation. This extension allows imaging centers to schedule patients more efficiently throughout the day and serve larger geographic regions.
The dual production pathway flexibility is particularly valuable from a clinical operations perspective. Gallium-68 has traditionally been produced via generators with limited daily capacity, creating bottlenecks in high-volume centers. The cyclotron production option using both the GE FASTlab™ system and ARTMS QUANTM Irradiation System® enables significantly higher-volume production, potentially allowing centers to scan 5-10× more patients daily compared to generator-only methods.
From a clinical application standpoint, Gozellix® maintains the same diagnostic indications as first-generation PSMA agents – for initial staging of men with suspected metastatic disease and for biochemical recurrence evaluation. The safety profile appears consistent with existing PSMA-PET agents, with minimal adverse reactions reported (
As the second FDA-approved PSMA imaging agent from Telix, this represents portfolio expansion rather than an entirely novel capability. However, the operational improvements and reimbursement status combine to potentially expand the addressable market for PSMA-PET imaging, which remains underutilized relative to clinical guidelines recommendations.
09/23/2025 – 10:15 AM
MELBOURNE, Australia and INDIANAPOLIS, Sept. 24, 2025 (GLOBE NEWSWIRE) — Telix Pharmaceuticals Limited (ASX: TLX, NASDAQ: TLX, “Telix”) today announces that the United States (U.S.) Centers for Medicare & Medicaid Services (CMS) has granted Transitional Pass-Through (TPT) payment status for Gozellix® (kit for the preparation of gallium-68 (68Ga) gozetotide injection), Telix’s next-generation PSMA-PET1 imaging agent for prostate cancer.
This designation enables separate reimbursement for Gozellix® under the Hospital Outpatient Prospective Payment System (HOPPS), effective 1 October 2025, and marks a significant milestone in Telix’s U.S. commercial strategy. Gozellix® has already been assigned a permanent Healthcare Common Procedure Coding System (HCPCS) Level II code A9616 to be recognized by CMS and commercial health insurers, effective 1 October 20252. Additionally, patients are not subject to the 20% patient coinsurance under TPT.
After radiolabelling with 68Ga, Gozellix® is indicated for PET scanning of PSMA positive lesions in men with prostate cancer who have suspected metastasis and are candidates for initial definitive therapy, and those with suspected biochemical recurrence (BCR) based on elevated serum prostate-specific antigen (PSA) level3.
Gozellix® is a novel imaging agent offering a longer shelf life of up to six hours and an extended distribution radius compared to existing gallium-based products, helping to overcome many of the logistical barriers that have historically limited access to PSMA-PET imaging4. Its innovative formulation enables scalable production, with preparation possible via gallium generators (50mCi and 100mCi) or cyclotron-based methods. This flexibility has the potential to significantly improve efficiency, scheduling flexibility, and throughput for scanning clinics5. Cyclotron production of Gozellix® is supported by the GE FASTlab™6 solid and liquid target production system and Telix’s ARTMS QUANTM Irradiation System® (QIS®), the market-leading cyclotron solid target technology, enabling large-scale production across both commercial networks and academic centers.
The Centers for Medicare & Medicaid Services (CMS) decision to grant Transitional Pass-Through (TPT) payment status to Telix Pharmaceuticals’ Gozellix marks a pivotal moment in prostate cancer diagnostics, potentially reshaping the reimbursement landscape and expanding access to this advanced imaging agent. Starting October 1, 2025, hospitals will receive separate payments for Gozellix under the Hospital Outpatient Prospective Payment System (HOPPS), a move that not only streamlines billing but also alleviates the financial burden on patients by eliminating the 20% coinsurance typically associated with such procedures.
This development underscores the growing importance of precision medicine in oncology and highlights the economic incentives needed to drive the adoption of innovative technologies. Gozellix’s TPT status is expected to encourage wider utilization, offering improved diagnostic accuracy for men with suspected metastatic prostate cancer or biochemical recurrence. The longer shelf life and broader distribution radius compared to existing agents will further enhance its practicality in clinical settings.
Industry analysts predict that this regulatory tailwind could significantly bolster Telix’s market position, positioning Gozellix as a preferred choice for PSMA-PET imaging. Moreover, the dual production pathways—via gallium generators and cyclotron-based methods—provide added flexibility for imaging centers, allowing them to adapt to varying patient volumes without compromising efficiency. Telix’s strategic investment in cyclotron technology through its ARTMS QUANTM Irradiation System® appears particularly prescient, enabling large-scale production to meet anticipated demand. All those factors potentially translate to higher revenue for Telix in the US market.
Illuccix®, Telix’s already approved imaging agent, and now Gozellix® with its extended shelf life, and more importantly its TPT reimbursement status will enable more patients and providers across the U.S. to have access to PSMA-PET/CT imaging.
Granting TPT status for Gozellix is a strong endorsement of the clinical value of our next-generation imaging agent. Gozellix is already available nationally, and this reimbursement milestone will reduce the out-of-pocket burden for patients, enhance patient access to advanced prostate cancer imaging and simplify payment for providers. As the only provider with two FDA-approved and reimbursed products in this class, we are pleased to make PSMA-PET/CT imaging accessible to more patients and providers across the U.S.”
Risk for Misinterpretation
Image interpretation errors can occur with GOZELLIX PET. A negative image does not rule out the presence of prostate cancer, and a positive image does not confirm the presence of prostate cancer. Gallium Ga-68 gozetotide uptake is not specific for prostate cancer and may occur with other types of cancer as well as non-malignant processes such as Paget’s disease, fibrous dysplasia, and osteophytosis. Clinical correlation, which may include histopathological evaluation of the suspected prostate cancer site, is recommended.
The performance of GOZELLIX for imaging of biochemically recurrent prostate cancer seems to be affected by serum PSA levels and by site of disease. The performance of GOZELLIX for imaging of metastatic pelvic lymph nodes prior to initial definitive therapy seems to be affected by Gleason score.
Radiation Risks
Gallium Ga-68 gozetotide contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk for cancer. Ensure safe handling to minimize radiation exposure to the patient and healthcare providers. Advise patients to hydrate before and after administration and to void frequently after administration.
Hypersensitivity Reactions to Sulfites
Ascorbic Acid Stabilizer contains sodium metabisulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in non-asthmatic people.
The safety of gallium Ga-68 gozetotide was evaluated in 960 patients in the PSMA-PreRP and PSMABCR studies, each receiving one dose of gallium Ga-68 gozetotide. The average injected activity was 188.7 ± 40.7 MBq (5.1 ± 1.1 mCi). The most commonly reported adverse reactions were nausea, diarrhea, and dizziness, occurring at a rate of 1%.
Androgen deprivation therapy and other therapies targeting the androgen pathway Androgen deprivation therapy (ADT) and other therapies targeting the androgen pathway, such as androgen receptor antagonists, can result in changes in uptake of gallium Ga-68 gozetotide in prostate cancer. The effect of these therapies on performance of gallium Ga-68 gozetotide PET has not been established.
