Telix Pharmaceuticals Initiates Phase 1 Trial of TLX300-CDx for Advanced Soft Tissue Sarcoma
Melbourne, Australia, April 02, 2025 – Telix Pharmaceuticals Limited (ASX: TLX, NASDAQ: TLX), a leading pharmaceutical company specializing in the development of diagnostic and therapeutic radiopharmaceuticals, announced today that the first patient has been dosed in the Phase 1 ZOLAR1 trial of TLX300-CDx (89Zr-olaratumab) at the Melbourne Theranostic Innovation Centre (MTIC) in Melbourne, Australia.
About Telix Pharmaceuticals and TLX300-CDx
Telix Pharmaceuticals is a profit-focused, intense, and professionally educated biotech company with a mission to develop and commercialize innovative diagnostic and therapeutic radiopharmaceuticals. Their latest offering, TLX300-CDx (89Zr-olaratumab), is a diagnostic radiopharmaceutical designed to target ZOLA R1 positive tumors, including advanced, metastatic soft tissue sarcoma (STS).
The Phase 1 ZOLAR1 Trial
The Phase 1 ZOLAR1 trial is a multi-center, open-label, single-arm study designed to evaluate the safety, tolerability, pharmacokinetics, and dosimetry of TLX300-CDx in patients with advanced, metastatic STS. The trial will enroll approximately 30 patients and will be conducted at multiple sites across the United States and Europe. The primary objectives of the study are to assess the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of TLX300-CDx. Secondary objectives include evaluating the imaging characteristics and potential therapeutic benefit of the radiopharmaceutical.
Impact on Patients
For patients with advanced, metastatic STS, the initiation of the Phase 1 ZOLAR1 trial represents an important step forward in the development of a potential new treatment option. Soft tissue sarcomas are rare, aggressive, and difficult-to-treat cancers that often require multiple lines of therapy. Current treatment options include surgery, chemotherapy, and radiation therapy, but these approaches have limitations in terms of their efficacy and side effects. TLX300-CDx, if successful, could provide a more targeted and personalized approach to treating STS, potentially improving patient outcomes and quality of life.
Impact on the World
The initiation of the Phase 1 ZOLAR1 trial is not only significant for patients with advanced, metastatic STS but also for the broader medical community. Soft tissue sarcomas affect approximately 13,000 people in the United States each year, and the global incidence is estimated to be around 40,000 new cases annually. A successful outcome from the Phase 1 trial could lead to the development of a new and effective treatment option for these patients, potentially saving countless lives and reducing the burden of this disease on individuals, families, and healthcare systems around the world.
Conclusion
The initiation of the Phase 1 ZOLAR1 trial of TLX300-CDx at the Melbourne Theranostic Innovation Centre marks an important milestone in the development of a potential new treatment option for patients with advanced, metastatic soft tissue sarcoma. This trial has the potential to significantly impact the lives of patients with this rare and aggressive cancer, as well as the broader medical community. Telix Pharmaceuticals’ commitment to developing innovative diagnostic and therapeutic radiopharmaceuticals continues to drive progress in the field and offers hope for those affected by this debilitating disease.
