- Phase III VISION study with 177Lu-PSMA-617 met both primary endpoints, significantly improving overall survival (OS) and radiographic progression-free survival (rPFS) in patients with PSMA-positive metastatic castration-resistant prostate cancer1
- VISION trial findings to be presented at upcoming medical meeting, with regulatory submissions in the US and EU anticipated in 2021
- Novartis is committed to reimagining prostate cancer through targeted radioligand therapy with 177Lu-PSMA-617
- More than 15 dedicated early to late development and research programs underway to identify the next wave of radioligand therapies for cancer
Basel, March, 23, 2021 — Novartis today reported the first interpretable results of the Phase III VISION study evaluating the efficacy and safety of 177Lu-PSMA-617, a targeted radioligand therapy in patients with progressive PSMA-positive metastatic castration-resistant prostate cancer (mCRPC) compared to best standard of care alone. The trial met both primary endpoints of overall survival and radiographic progression-free survival1, helping to move closer the ambition of becoming the targeted treatment for >80% of patients with advanced prostate cancer. The safety profile was consistent with data reported in previous clinical studies1. Results from the VISION trial will be presented at an upcoming medical meeting and included in US and EU regulatory submissions.
“Patients with metastatic castration-resistant prostate cancer have a less than 1 in 6 chance of surviving 5 years2 and need new treatment options. These groundbreaking data confirm our belief in the potential of 177Lu-PSMA-617 to reimagine outcomes for these patients through phenotypic precision medicine. We intend to submit these data to regulatory authorities as soon as possible,” said John Tsai, Head of Global Drug Development and Chief Medical Officer for Novartis. “We would like to thank the patients who volunteered to participate in this study as well as the clinical teams at each of the trial sites. We would not be able to realize our commitment to reimagining medicine without the partnership of patients and their families.”
Radioligand therapy combines a targeting compound that binds to markers expressed by tumors and a radioactive isotope, causing DNA damage that inhibits tumor growth and replication. This therapeutic approach enables targeted delivery of radiation to the tumor, while limiting damage to the surrounding normal tissue. Novartis has established global expertise and specialized supply chain and manufacturing capabilities across its network of four radioligand therapy production sites, and is further increasing capacity to ensure delivery of radioligand therapies like 177Lu-PSMA-617 to patients in need.
Novartis is the only pharmaceutical company which is pursuing four different cancer treatment platforms. These include radioligand therapy, cell and gene therapy, and targeted therapy and immunotherapy, with an opportunity to combine these platforms for the best outcomes for each cancer patient.
About Advanced Prostate Cancer
Prostate cancer is a form of cancer that develops in the prostate gland, a small walnut shaped gland in the pelvis of men. In castration resistant prostate cancer (CRPC), the tumor shows signs of growth, such as rising Prostate Specific Antigen (PSA) levels, despite the use of hormone treatments that lower testosterone3. In metastatic CRPC (mCRPC), the tumor spreads to other parts of the body, such as neighboring organs or bones and remains unresponsive to hormone treatment4. The five-year survival rate for patients with mCRPC is approximately 15%2.
About Phenotypic Precision Medicine in Advanced Prostate Cancer
Despite advances in prostate cancer care, there is a high unmet need for new targeted treatment options to improve outcomes for patients with metastatic castration resistant prostate cancer. More than 80% of prostate cancer tumors highly express a phenotypic biomarker5 called Prostate Specific Membrane Antigen (PSMA)4,6-9, making it a promising diagnostic (through positron emission tomography (PET) scan imaging) and therapeutic target for radioligand therapy6.
177Lu-PSMA-617 is an investigational PSMA-targeted radioligand therapy for metastatic castration-resistant prostate cancer. It is a type of precision cancer treatment combining a targeting compound (ligand) with a therapeutic radioisotope (a radioactive particle)10-12. After administration into the bloodstream, 177Lu-PSMA-617 binds to prostate cancer cells that express PSMA13, a transmembrane protein, with high tumor-to-normal tissue uptake10,14,15. Once bound, emissions from the radioisotope damage tumor cells, disrupting their ability to replicate and/or triggering cell death. The radiation from the radioisotope works over very short distances to limit damage to surrounding cells14,16.
VISION is an international, prospective, randomized, open-label, multicenter, phase III study to assess the efficacy and safety of 177Lu-PSMA-617 (7.4 GBq administered by i.v. infusion every 6 weeks for a maximum of 6 cycles) plus investigator-chosen best standard of care in the investigational arm, versus best standard of care in the control arm17. Patients with PSMA PET-scan positive mCRPC, and progression after prior taxane and androgen receptor-directed therapy (ARDT), were randomized in a 2:1 ratio in favor of the investigational arm. The alternate primary endpoints were rPFS and OS. The study enrolled 831 patients1.
