FDA Expands Pluvicto Approval for Earlier Metastatic Prostate Cancer
- The FDA has expanded Pluvicto’s approval, allowing it to be used earlier for adults with PSMA-positive metastatic prostate cancer that has not yet become resistant to androgen-pathway treatment.
- For this newly approved use, Pluvicto is given with an ARPI and continued testosterone-lowering treatment. It does not replace hormone therapy.
- In the analysis supporting the approval, adding Pluvicto reduced the rate over time of radiographic progression or death by 28%. Whether the combination helps patients live longer has not yet been established.
The FDA has approved Pluvicto (lutetium Lu 177 vipivotide tetraxetan) in combination with an androgen receptor pathway inhibitor (ARPI) for adults with PSMA-positive metastatic androgen pathway modulation-naïve or -sensitive prostate cancer, the FDA’s updated terminology for metastatic hormone-sensitive prostate cancer (mHSPC).

The decision is supported by results from the Phase III PSMAddition clinical trial.

How Pluvicto Works
Pluvicto (lutetium Lu 177 vipivotide tetraxetan) offers a targeted treatment option for men with metastatic castration-resistant prostate cancer that is PSMA-positive.
WATCH: Radioligand Therapy: Who Is Eligible & How Does It Work?
Castration-resistant means that the cancer has continued to grow despite a reduction in testosterone levels. PSMA-positive means their tumors express the PSMA protein, which can be detected through imaging.
Pluvicto uses the PSMA molecule as a target because the protein is often found on the surface of prostate cells. While normal prostate cells have some PSMA, prostate cancer cells — especially those in advanced or aggressive stages — have a significantly higher concentration of it.
The ligand component of Pluvicto binds tightly to PSMA. Once attached, the radiolabeled component, lutetium-177, emits beta radiation over a short distance — typically a few millimeters. This radiation damages the DNA of the nearby cancer cells, causing them to die. The proximity effect of this therapy is crucial; it ensures that healthy tissues, which either don’t express PSMA or express very little of it, are exposed to far less radiation than the cancer cells.
Before receiving Pluvicto, prostate cancer patients undergo a PSMA scan to confirm that their tumor expresses the target protein.
Dr. William Kevin Kelly, Chair of Medical Oncology at Thomas Jefferson University’s Sidney Kimmel Cancer Center in Philadelphia, tells SurvivorNet, “We have to understand if your tumor takes up that protein,” Dr. Kelly notes. “If not, this drug can cause more problems than good.”
Additional eligibility criteria include appropriate bone marrow function (which produces blood cells) and healthy kidney function, as the treatment can pose risks if these conditions aren’t met.
It can be an option for these patients when they have already been treated with either hormone therapy or a combination of hormone therapy and chemotherapy.

What This Means for Eligible Prostate Cancer Patients
This approval significantly expands Pluvicto’s use beyond its earlier indication in metastatic castration‑resistant prostate cancer (mCRPC).
Previously, the drug was reserved for patients who had already undergone chemotherapy. In March 2025, the FDA broadened its authorization, allowing Pluvicto to be used earlier in treatment for adults with PSMA‑positive mCRPC who had received an ARPI and were candidates to delay taxane‑based chemotherapy.
WATCH: The Promise Of Radioligand Therapy
With Pluvicto now approved across all stages of PSMA‑positive metastatic prostate cancer, the number of eligible patients has nearly doubled.
“Metastatic hormone‑sensitive prostate cancer is incurable, and about half of men progress within 20 months, highlighting the need for differentiated, precision approaches earlier in the disease journey,” Novartis said in a press release.
Novartis President Victor Bultó added, “Pluvicto is now approved across PSMA‑positive metastatic prostate cancer, nearly doubling the number of patients who may benefit from this targeted approach.”

The Phase III PSMAddition Trial Behind the Approval
In the PSMAddition study, Pluvicto, combined with standard-of-care androgen receptor pathway inhibitor (blocks the testosterone from getting in the prostate cancer cells) plus androgen deprivation therapy (lowers or blocks testosterone, which fuels the growth of most prostate cancer cells), reduced the risk of disease progression or death by 28% (HR 0.72; 95% CI: 0.58–0.90) compared with standard therapy alone.
An additional analysis showed a 33% reduction in the risk of progression or death (HR 0.67; 95% CI: 0.55–0.82), along with a positive trend toward improved overall survival (HR 0.80; 95% CI: 0.63–1.01). Overall survival data are still maturing ahead of the final analysis.
Pluvicto Side Effects
Dr. Aihua Edward Yen, a medical oncologist at Baylor College of Medicine, explains that Pluvicto’s side effects depend on how the radiation behaves in the body.
“Radiation potentially can cause your blood counts to come down, so we’ll usually have to watch that very carefully. It can also go to other areas of your body where PSMA is expressed, and these would be considered off‑target effects,” he says.
Common side effects include:
- Dry mouth (xerostomia)
- Fatigue
- Stomach discomfort
- Nausea
- Vomitting
- Constipation or mild diarrhea
- Reduced appetite & Changes in taste
- Low red or white blood cell counts (anemia or leukopenia)
- Joint pain (arthralgia) or back pain
Patients require monitoring of blood counts and kidney function throughout treatment.
Questions Patients Might Ask About Pluvicto and PSMA-Targeted Therapy
- How do I know if my prostate cancer is PSMA-positive and whether Pluvicto could help me?
- How much can Pluvicto slow my cancer compared to standard treatment alone?
- Is the benefit worth the side effects and extra visits for treatment?
- Should Pluvicto be used early, when my cancer still responds to hormone therapy, or later?
- How will my doctor decide the best time to start it?
- Can the number of treatments be adjusted based on how I respond?
- Will Pluvicto be given alongside hormone therapy, chemotherapy, or other medications?
- Could Pluvicto help me live longer, or just slow the cancer’s growth?
- How much will it cost, and is it covered by insurance?
- What benefits have been proven?
- What questions are still being researched before Pluvicto becomes a standard treatment for all patients?
