MELBOURNE, Australia and INDIANAPOLIS, Sept. 02, 2026 (GLOBE NEWSWIRE) -- Telix Pharmaceuticals Limited (ASX: TLX, NASDAQ: TLX, “Telix”) today announced completion of patient enrollment in the Phase 3 BiPASS™ study of its commercial PSMA-PET¹ imaging agents, Illuccix® (kit for the preparation of gallium Ga68 gozetotide injection) and Gozellix® (kit for the preparation of gallium Ga68 gozetotide injection) for prostate cancer imaging in the pre-biopsy setting. Telix has also aligned with the United States (U.S.) Food and Drug Administration (FDA) on a New Drug Application (NDA) pathway for BiPASS that, if approved, would support reimbursement as a new product and broaden patient access.

BiPASS (Biopsy of the Prostate Avoidance Stratification Study²) is the first registrational study of ⁶⁸Ga-PSMA-PET imaging in the pre-biopsy setting. The study aims to evaluate whether the combination of MRI³ and PSMA-PET/CT⁴ with Telix’s proprietary ⁶⁸Ga-PSMA-PET agents can further improve diagnostic accuracy, reduce unnecessary biopsies, or improve targeting of biopsy compared with current standard practice. A total of 350 patients were enrolled in the U.S. and Australia in this prospective, open-label Phase 3 trial.

Globally, more than three million prostate biopsies are performed each year⁵, yet up to 75% are found to be negative⁶. Patient compliance remains a significant clinical challenge with approximately one in four patients declining a physician recommendation to undergo biopsy⁷. Biopsy is often stressful and painful, may lead to complications, and delivers no real diagnostic benefit for many patients⁸.

BiPASS builds on the clinical foundation established by the landmark PRIMARY⁹ and PRIMARY2¹⁰ studies, which demonstrated that combining ⁶⁸Ga-PSMA-PET imaging with MRI can significantly improve the detection of clinically significant prostate cancer while reducing unnecessary biopsies by almost 50 percent. If BiPASS meets its primary objectives, the data, alongside evidence from PRIMARY and PRIMARY2, have the potential to shift ⁶⁸Ga-PSMA-PET beyond its current use in initial staging and secondary re-staging at disease recurrence and establish precision imaging as a critical step in initial diagnosis. Earlier and more accurate identification of clinically significant disease could improve patient selection and treatment decisions, reduce unnecessary biopsies, and potentially decrease the long-term patient burden and healthcare cost of prostate cancer recurrence. Successful implementation of BiPASS could broaden access to ⁶⁸Ga-PSMA-PET imaging across a substantially larger patient population.

Professor Louise Emmett, Director of Theranostics and Nuclear Medicine, St Vincent’s Hospital and BiPASS Investigator, said, “Completing patient enrollment in BiPASS is an important milestone for men with suspected prostate cancer, particularly those with equivocal MRI findings. The PRIMARY and PRIMARY2 studies demonstrated that ⁶⁸Ga-PSMA-PET, when used alongside MRI, can safely halve the number of biopsies required without missing clinically significant prostate cancer. BiPASS now has the potential to fundamentally change the current standard of care, streamlining the diagnostic pathway, accelerating treatment decision-making and helping to ensure that men receive the most appropriate therapy earlier in their treatment journey.”

Dr. Brian Mazzarella, Vice President of Research for Urology America and BiPASS Investigator added, “PSMA-PET imaging with tracers such as Illuccix and Gozellix has already changed how we stage and manage prostate cancer. By combining the functional information from PSMA-PET with the detailed anatomic information provided by MRI, we have an unprecedented opportunity to improve the detection of clinically significant prostate cancer and guide more informed diagnostic decisions. For patients, this approach has the potential to reduce unnecessary procedures, lower procedural risk, ease anxiety, and ultimately enable more precise, individualized treatment decision-making.”

Dr. David N. Cade, Telix Group Chief Medical Officer, commented, “Recruitment of BiPASS was completed rapidly, reflecting strong enthusiasm from clinicians and patients for a more accurate, non-invasive approach to diagnosis. We believe BiPASS may represent a transformative event in the management of prostate cancer, alongside the compelling data from the PRIMARY studies. Instead of asking how best to stage prostate cancer, clinicians may increasingly use advanced imaging to determine which men need to undergo biopsy in the first place. Telix is uniquely positioned to define and lead this patient-first approach that, if approved, would represent a new clinical application with a reimbursement pathway that facilitates much broader patient access to gallium-based PSMA-PET.”

About Illuccix® (kit for the preparation of gallium Ga 68 gozetotide injection)

Illuccix, after radiolabeling with ⁶⁸Ga, 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, those with suspected recurrence based on elevated serum prostate-specific antigen (PSA) level, and for selection of patients who are indicated for PSMA-directed therapy as described in the prescribing information of the therapeutic products.

IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS

Risk for Misinterpretation
Image interpretation errors can occur with Illuccix 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.

Imaging Prior to Initial Definitive or Suspected Recurrence Therapy
The performance of Illuccix for imaging of biochemically recurrent prostate cancer seems to be affected by serum PSA levels and by site of disease. The performance of Illuccix 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.

ADVERSE REACTIONS
The safety of gallium Ga 68 gozetotide was evaluated in 960 patients in the PSMA-PreRP and PSMA-BCR 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%.

In the VISION study, 1003 patients received one dose of gallium Ga 68 gozetotide intravenously with the amount of radioactivity 167.1 ± 23.1 MBq (4.52 ± 0.62 mCi). Adverse reactions occurring at ≥0.5% in patients with metastatic prostate cancer who received gallium Ga 68 gozetotide injection in the clinical study were fatigue (1.2%), nausea (0.8%), constipation (0.5%), and vomiting (0.5%).
Adverse reactions occurring at a rate of < 0.5% in the VISION study were diarrhea, dry mouth, injection site reactions, including injection site hematoma and injection site warmth and chills.

Injection site pain has been identified during post-approval use of ILLUCCIX.

DRUG INTERACTIONS
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.
