Real-world Use of Lutetium (177Lu) Vipivotide Tetraxetan in China(PSMAreal CN) (PSMAreal)

Real-world Use of Lutetium (177Lu) Vipivotide Tetraxetan Injection in Metastatic Prostate Cancer: an Observational, Multicenter, Prospective Cohort Study in China (PSMAreal CN)

This non-interventional, observational, multicenter, prospective cohort study is designed to investigate the treatment patterns of mPC patients treated with lutetium (177Lu) vipivotide tetraxetan, as well as their clinical outcomes, real-world characteristics, and quality of life during the treatment period and up to one year after treatment completion.

Study Overview

• Status: Recruiting
• Conditions: Metastatic Prostate Cancer

Detailed Description

The study population will be divided into two cohorts, enrolling patients with mCRPC and mHSPC, respectively. Patients planned to receive lutetium (177Lu) vipivotide tetraxetan treatment according to treating physician's assessment will be enrolled in the study upon signing an informed consent form. Patients must meet all inclusion criteria defined in the protocol and not meet any exclusion criteria. The patients' medical history, prostate cancer disease characteristics, demographics, and baseline data will be collected through medical records and examination reports. Treatment patterns, treatment outcomes, and HRQoL data will be collected during study follow-up visits through patient records, examination reports, and self-reported data. This study does not have a control group; instead, a self-control method will be used, with the patients' baseline data before the start of treatment serving as the control for efficacy, safety, and HRQoL assessments. The index date for this study is defined as the date of the first administration of lutetium (177Lu) vipivotide tetraxetan

Prostate cancer disease characteristics: Number of patients with carcinoembryonic Antigen (CEA)		From 1 month before the index date to the index date
Adverse events		From the index date to 1 year after the EOT visit
FACT-P score	The FACT-P was developed to measure the health-related quality of life (HRQOL) in patients diagnosed with prostate cancer. It extends the general FACT-G scale, which assesses cancer patients' overall quality of life, by adding specific items related to prostate cancer therapy. The FACT-P consists of two main sections: FACT-G: A general section that covers four domains: Physical Well-Being (PWB)，Social/Family Well-Being (SWB)，Emotional Well-Being (EWB)，Functional Well-Being (FWB); Prostate Cancer Specific Section: Focuses on issues unique to prostate cancer patients, such as urinary symptoms, sexual health, and the side effects of treatment. The scoring system for the FACT-P uses a 5-point Likert scale (from 0 to 4，from good to bad). Scores are calculated across different domains and subscales, and the total score is calculated by summing the scores across all domains, providing a range of 0 to 156. A high FACT-P score indicates a worse outcome.	From 1 month before the index date to 1 year after the EOT visit
BPI-SF score	Brief Pain Inventory-Short Form (BPI-SF). The Brief Pain Inventory (BPI) rapidly assesses the severity of pain and its impact on functioning. BPI assessment areas including severity of pain, impact of pain on daily function, location of pain, pain medications and amount of pain relief in the past 24 hours or the past week. No scoring algorithm, but "worst pain" or the arithmetic mean of the four severity items can be used as measures of pain severity; the arithmetic mean of the seven interference items can be used as a measure of pain interference.	From 1 month before the index date to 1 year after the EOT visit
EQ-5D-5L questionnaire score	EuroQol 5-Dimension 5-Level (EQ-5D-5L). The 5-level EQ-5D version (EQ-5D-5L) descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.	From 1 month before the index date to 1 year after the EOT visit
FACT-RNT score	Functional Assessment of Cancer Therapy - Radionuclide Therapy (FACT-RNT). The FACT-RNT was designed for use and future adaptation with a broad variety of RNT agents with different molecular targeting mechanisms and radioisotopes. The FACT-RNT, a 15-item measure of symptoms/toxicities with higher total scores(range:0-60) indicating less symptom burden.	From 1 month before the index date to 1 year after the EOT visit
