Summary
Most dosing, administration route, and indication framing match the provided label excerpts (notably 7.4 GBq/200 mCi IV every 6 weeks for 6 doses or until progression/unacceptable toxicity). However, the response includes an explicit statement that the “label does not include dosing reductions/individualized dosing by baseline lab values,” which is not supported because the label excerpt states dosage modifications exist and refers to adverse-reaction severity and monitoring (including labs such as CBC and kidney function).

Accurate Statements
Pluvicto is administered as an IV infusion.
Section 2.5 states the recommended dosage may be administered intravenously as an injection using the syringe method, as an infusion using the gravity method, or as an infusion using the peristaltic pump method.
The standard Pluvicto regimen is 7.4 GBq (200 mCi) every 6 weeks for up to 6 doses.
Section 2.3: “7.4 GBq (200 mCi) intravenously every 6 weeks for 6 doses, or until disease progression, or unacceptable toxicity.”
Each Pluvicto cycle is separated by about 6 weeks.
Section 2.3: “every 6 weeks”.
Pluvicto treatment continues on this schedule until 6 total doses are reached or treatment is stopped earlier due to toxicity or disease progression.
Section 2.3: “for 6 doses, or until disease progression, or unacceptable toxicity.”
Pluvicto treatment is continued every 6 weeks and may be stopped before completing 6 doses depending on tolerability and clinical decision-making.
Section 2.3 (stopping criteria: progression or unacceptable toxicity) and Section 2.4 (dose modifications/withhold/reduce/discontinue for adverse reactions).
The described Pluvicto dosing is the standard schedule tied to its labeled use in metastatic castration-resistant prostate cancer after prior therapies.
Section 1 indicates use in adult PSMA-positive mCRPC after ARPI therapy (and appropriate to delay taxane chemotherapy or after taxane chemotherapy), and Section 2.3 provides the recommended dosing schedule for PLUVICTO.
Pluvicto dosing described above (7.4 GBq/200 mCi every 6 weeks) is the activity of the radiopharmaceutical delivered each time.
Section 2.3 specifies “recommended PLUVICTO dosage is 7.4 GBq (200 mCi) intravenously every 6 weeks…” and Section 3/16 describe the vial contains 7.4 GBq (200 mCi) as a single-dose.
Unsupported Statements
The provided labeling information does not include dosing reductions or individualized dosing by baseline lab values.
The provided label excerpt includes dosage modifications for adverse reactions (Section 2.4) and instructs performing complete blood counts and kidney function testing before and during treatment with withholding/reductions/discontinuation based on severity of myelosuppression and renal toxicity (Sections 5.2 and 5.3). This contradicts the claim that the label does not include dosing reductions or individualized dosing by baseline lab values.

Important Omissions
Patient selection details based on PSMA PET expression (LOCAMETZ or another approved PSMA PET product) were not mentioned in the dosing-focused statements.
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
Low
Most schedule and stopping criteria are consistent with the label excerpt. The main issue is an inaccurate statement denying individualized dosing/label-based dose modifications tied to adverse-reaction severity supported by lab monitoring (CBC/kidney function), which could mislead about label-consistent dose modification practice.

Recommendation

Primary Issue
Incorrect claim that the label does not include dosing reductions or individualized dosing by baseline lab values, despite label-provided dosage modifications and lab-based monitoring guidance.
Suggested Improvement
Remove or revise the statement denying dosing reductions/individualized dosing by lab values; instead, reflect that the label provides dosage modifications for adverse reactions with lab monitoring (CBC and kidney function) guiding withholding/reduction/discontinuation.
