The United States Food and Drug Administration (FDA) has expanded the approval for lutetium Lu 177 vipivotide tetraxetan (Pluvicto, Novartis) to include adults with prostate-specific membrane antigen (PSMA)–positive metastatic castration-resistant prostate cancer (mCRPC), who have received androgen receptor pathway inhibitor (ARPI) therapy and are considered appropriate to delay taxane-based chemotherapy.
The radioligand therapeutic agent was previously approved for the treatment of PSMA-positive mCRPC in patients who have already received ARPI therapy and taxane-based chemotherapy. Approval for the expanded indication was based on efficacy demonstrated in the randomized, open-label, phase 3 PSMAfore trial.
Treatment in 468 patients who progressed on one ARPI and who were deemed appropriate for delay of taxane-based chemotherapy was associated with improved radiographic progression-free survival (rPFS) and overall survival (OS) vs a different ARPI.
Patients were randomized 1:1 to receive lutetium Lu 177 vipivotide tetraxetan (7.4 GBq [200 mCi] every 6 weeks for six doses) or to receive a different ARPI, according to a statement from the FDA. Those who progressed on the new ARPI were allowed to cross over to the experimental therapy arm after progression, and 60% did so.
Median rPFS was 9.3 vs 5.6 months in the experimental and control arms, respectively (hazard ratio [HR], 0.41). Median OS durations were 24.5 and 23.1 months, respectively (HR, 0.91), but the difference in OS did not reach statistical significance.
Adverse reactions were consistent with the known safety profile of lutetium Lu 177 vipivotide tetraxetan, which includes possible radiation exposure, myelosuppression, and renal toxicity.
The recommended dose, according to prescribing information, is 7.4 GBq (200 mCi) administered intravenously every 6 weeks for six doses or until disease progression or unacceptable toxicity.
“The earlier indication for Pluvicto could really change our treatment paradigms for patients with mCRPC. It offers a targeted therapy that better delays disease progression compared to a second ARPI,” Michael Morris, MD, of Memorial Sloan Kettering Cancer Center, New York, and the principal investigator of the study in the United States stated in a Novartis press release. “This approval is a significant step forward and should open the doorway to a therapy that has clear clinical advantages for the patient with mCRPC who has progressed on one ARPI and has not received chemotherapy.”
