MELBOURNE, Australia, Sept. 27, 2022 /PRNewswire/ -- Telix Pharmaceuticals Limited (ASX: TLX, Telix, the Company) and GenesisCare, the largest provider of integrated cancer care in Australia, today announce that a first patient has been enrolled in the Phase II ProstACT TARGET study of Telix's prostate cancer antibody therapy candidate TLX591 (177Lu-DOTA-rosopatamab), in patients experiencing a first recurrence of prostate-specific antigen (PSA) after initial therapy for prostate cancer.
Telix's ProstACT therapeutic program is evaluating the efficacy of the Company's prostate-specific membrane antigen- (PSMA-) targeting lutetium-177 (177Lu)-labelled therapeutic antibody, TLX591, in various stages of prostate cancer, from first recurrence to advanced metastatic disease. The primary focus of the ProstACT series of studies is to complete the pivotal Phase III ProstACT GLOBAL study in a second-line setting in patients with metastatic castration-resistant prostate cancer (mCRPC) progressing on first-line novel androgen agents.
The TARGET study, a collaboration between Telix and research partner, GenesisCare, is exploring the potential of TLX591 in combination with external radiation in patients at an earlier stage in their prostate cancer, providing direction for future indication expansion. The study, which targets enrolment of 50 patients across multiple Australian sites, enrolled the first patient at GenesisCare's integrated cancer centre at the St John of God Hospital Murdoch campus in Western Australia. The clinical trial is being run through GenesisCare's global Contract Research Organisation and its Australian network of dedicated theranostics centres.
The third concurrent study in the ProstACT program, ProstACT SELECT, is a theranostic (imaging and therapy) Phase I radiogenomics study to demonstrate the utility of Telix's imaging agent Illuccix® (kit for the preparation of gallium-68 (68Ga) Glu-urea-Lys(ahx)-hbed-CC, also known as 68Ga-PSMA-11 injection) to select patients for TLX591 therapy given as two doses 14 days apart.
Principal Investigator for the ProstACT TARGET study and GenesisCare Group Medical Director (Theranostics), Professor Nat Lenzo said, "I'm excited to commence this important study that builds on the momentum of ProstACT SELECT. With previous studies having confirmed the preliminary efficacy and safety profile of TLX591, GenesisCare is pleased to partner with Telix to further their therapeutic antibody-based program, which has potential to improve health outcomes for thousands of men living with prostate cancer in Australia and worldwide."
Telix Chief Medical Officer Dr. Colin Hayward added, "Enrolling a first patient in the ProstACT TARGET study is a significant milestone in Telix's overall clinical mission to support men with prostate cancer at every step in their journey with a PSMA antibody approach to targeted radiation therapy. Alongside ProstACT SELECT, this program will add value and clinical insight to Telix's antibody therapy candidate TLX591, as we progress global regulatory submissions for the ProstACT GLOBAL Phase III study. We wish to express our gratitude to Professor Nat Lenzo and his clinical team, as well as the patients who will contribute to the study."
