Lutetium Lu 177: Prostate Cancer Uses, Warnings, Side Effects, Dosage

Generic Name: lutetium Lu 177 vipivotide tetraxetan

Brand Name: Pluvicto

Drug Class: Radiopharmaceuticals

What is Lutetium Lu 177 vipivotide tetraxetan, and what is it used for?

Lutetium Lu 177 vipivotide tetraxetan is a radioligand therapy used for a specific type of advanced prostate cancer. Radioligand therapy is a targeted radiation treatment in which a radioactive chemical (radionuclide) is administered as an intravenous (IV) injection. Radioligand therapy is used to specifically target the cancer cells and kill them, and limit the harm to normal cells that can result from traditional radiation therapies.

Lutetium Lu 177 vipivotide tetraxetan is used to treat prostate-specific membrane antigen (PSMA)-positive, metastatic castration-resistant prostate cancer (mCRPC). These advanced metastatic prostate cancers do not respond to chemotherapy or treatments that lower testosterone. PSMA is a prostate-specific protein which is present in great amounts in the membranes of the cancer cells.

Lutetium Lu 177 vipivotide tetraxetan is a radioconjugate drug that contains vipivotide tetraxetan, a substance (ligand) that identifies and binds to PSMA on the cancer cells. The radionuclide lutetium Lu 177 then delivers radiation to the PSMA-expressing cells and the surrounding cells and destroys them.

Warnings

  • Lutetium Lu 177 vipivotide tetraxetan can cause fetal harm
  • May cause temporary or permanent infertility in males
  • Lutetium Lu 177 vipivotide tetraxetan contributes to the patient’s overall long-term cumulative radiation exposure, which increases the risk for cancer
  • Minimize radiation exposure to patients, medical personnel, and household contacts during and after treatment
  • Before patient is released, explain necessary radioprotection precautions to follow to minimize radiation exposure to others:
    • Patient must avoid close contact (less than 3 feet) for 2 days with others at home and for 7 days with children and pregnant women 
    • Patient must refrain from sexual activity for 7 days
    • Patient must sleep in a separate bedroom from other adults for 3 days, from children for 7 days, and from pregnant women for 15 days
  • Lutetium Lu 177 vipivotide may cause severe and life-threatening bone marrow suppression (myelosuppression) that can result in anemia, thrombocytopenia, leukopenia, and neutropenia
  • Perform complete blood cell counts before and during treatment and titrate the dose accordingly or discontinue therapy 
  • Advise patients to contact their healthcare provider in case of myelosuppression symptoms of (e.g., tiredness, weakness, pale skin, shortness of breath, bleeding or bruising more easily than normal, or difficulty in stopping bleeding) or frequent infections with signs such as fever, chills, sore throat, or mouth ulcers
  • Can be severely toxic to the kidney; ensure that patients increase oral fluid intake and advise patients to urinate as often as possible to reduce bladder radiation
  • Perform kidney function tests before and during treatment and adjust dosage accordingly or discontinue therapy based on severity of renal toxicity

What are the dosages of lutetium Lu 177 vipivotide tetraxetan?

Injection, solution for IV use

  • 1,000 MBq/mL (27 mCi/mL) single-dose vial

Castration-Resistant Prostate Cancer

  • Indicated for the treatment of men with prostate-specific membrane antigen (PSMA)-positive, metastatic castration-resistant prostate cancer (mCRPC) who have been treated with androgen receptor (AR) pathway inhibition and taxane-based chemotherapy
  • 7.4 GBq (200 mCi) IV every 6 weeks for up to 6 doses, or until disease progression, or unacceptable toxicity

Dosage Modifications

General recommendations

  • Management of adverse reactions may require temporary dose interruption (extending the dosing interval from every 6 weeks up to every 10 weeks), dose reduction, or permanent discontinuation
  • If treatment delay persists for longer than 4 weeks, treatment must be discontinued
  • Dose may be reduced by 20% to 5.9 GBq (160 mCi) once; do not re-escalate dose
  • If further adverse reactions occur that would require an additional dose reduction, treatment must be discontinued

Myelosuppression

  • Anemia, thrombocytopenia, leukopenia, or neutropenia
  • Grade 2: Withhold until improvement to Grade 1 or baseline
  • Grade 3 or higher: Withhold until improvement to Grade 1 or baseline, reduce dose by 20% to 5.9 GBq (160 mCi)
  • Recurrent Grade >3 myelosuppression after 1 dose reduction: Permanently discontinue

Renal toxicity

  • Withhold until improvement
    • Confirmed serum creatinine increase (Grade 2 or higher)
    • Confirmed creatinine clearance (CrCl) higher than 30mL/minute; calculate using Cockcroft-Gault equation with actual body weight
  • Withhold until improvement/baseline and reduce dose by 20%
    • CrCl confirmed increase 40% or higher from baseline AND
    • CrCl confirmed higher than 40% decrease from baseline; calculate using Cockcroft-Gault equation with actual body weight
