Pilot of 18F-DCFPyL-PSMA PET in mCRPC Patients Receiving 117Lu-Vipivotide Tetraxetan

Официальное название

A Pilot Study of 18F-DCFPyL-PSMA PET in Patients Receiving 177Lu-Vipivotide Tetraxetan Therapy for Metastatic Castrate-resistant Prostate Cancer

Обзор

The purpose of this research study is to see how well an imaging test, called 18FDCFPyL prostate specific membrane antigen (PSMA) positron emission tomography (PET), can show the extent of prostate cancer when comparing to 68Ga-PSMA-11 PET/CT (another type of diagnostic scan for prostate cancer).

Подробное описание

This is a one-arm single-stage prospective pilot study to determine how 18F-DCFPyL PSMA-PET/CT can be used as a diagnostic test before treatment with 177Lu-vipivotide tetraxetan, which is an approved therapy for advanced prostate cancer.

The U.S. Food and Drug Administration (FDA) has approved 18F-DCFPyL as a diagnostic agent (radiotracer) option for prostate cancer, though it is not specifically approved for participants who are due to receive 177Lu-vipivotide tetraxetan therapy.

This research study involves a single PET scan using the imaging agent 18F-DCFPyL and the collection of information from medical records.

Participation in this research study is expected to last about 12 months.

It is expected that about 30 people will take part in this research study. Progenics Pharmaceuticals, Inc. is funding this research study by providing funding and the imaging agent, 18F-DCFPyL.

Вмешательства

• Препарат 18F-DCFPyl
  Fluorine-labeled small molecule, via intravenous infusion per protocol.

Первичные конечные точки

• Proportion of Participants with PSMA-Positive Lesion [Срок оценки: 1 Day]

Критерии участия

Критерии включения

• Participants must have histologically or cytologically confirmed prostate cancer.
• Age ≥18 years.
• Participants must be planned for standard-of-care 177Lu-Vipivotide Tetraxetan therapy after the 18F-DCFPyL PSMA-PET.

-≥1 PSMA-avid lesion on 68Ga-PSMA-11 PSMA-PET performed within 120 days of study entry (to meet eligibility for 177Lu-Vipivotide Tetraxetan therapy).

• Ability and willingness to comply with the study procedures.
• Participants with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational agent are eligible for this trial.
• The effects of 18F-DCFPyL on the developing human fetus are unknown. For this reason and because radiopharmaceutical agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for 24 hours after the 18F-DCFPyL PSMA-PET scan.
• Ability to understand and the willingness to sign a written informed consent document.

Критерии исключения

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia.
• Contraindications to PET/CT, including severe claustrophobia.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to 18F-DCFPyL
• Any past or current condition that, in the opinion of the study investigators, would confound the results of the study or would pose additional risk or burden to the patient by their participation in the study.
