Brief Summary

The purpose of this study is to describe routine clinical practice with lutetium (177Lu) vipivotide tetraxetan on Health related quality of life (HRQoL) at baseline, on treatment, and post progression.

Detailed Description

This non-interventional observational, prospective cohort study is using primary data collection to describe the routine clinical practice and HRQoL of patients with Metastatic castration-resistant prostate cancer (mCRPC) initiating lutetium (177Lu) vipivotide tetraxetan using patient questionnaires.

Data will be collected at the following time points: pre-index (if patient is eligible), index date (first application of lutetium (177Lu) vipivotide tetraxetan), during treatment, at EoT, and during follow-up.

The duration of a treatment cycle is 6 weeks (± 1 week). Patients will be treated for up to 6 cycles (as per local label).

EoT visit / assessments will be performed after the last lutetium (177Lu) vipivotide tetraxetan application.

Follow-up period: patient data will be collected if available up to 1 year after EoT.

Primary Outcome Measures

Name	Time	Method
Functional Assessment of Cancer Therapy - Prostate (FACT-P)	Baseline, up to 1 year after end of treatment	FACT-P assesses symptoms/problems related to prostate carcinoma and its treatment. It is a combination of the FACT- General + the Prostate Cancer Subscale (PCS). The FACTGeneral (FACT-G) is a 27 item Quality of Life (QoL) measure that provides a total score as well as subscale scores: Physical (0-28), Functional (0-28), Social (0-28), and Emotional Well-being (0-24). The total score range is between 1-108, higher scores indicates better for total score and subscale scores. PCS is a 12-item prostate cancer subscale that asks about symptoms and problems specific to prostate cancer (Range 0-48, higher scores better). The FACT-P total score is the sum of all 5 subscale scores of the FACT-P questionnaire and ranges from 0-156. Higher scores indicate higher degree of functioning and better quality of life.
Time to initiation of pain medication	Up to 1 year after end of treatment	Time to initiation of pain medication is defined as time from index date to the first use of any pain medication or progression.
Time to prostate-specific antigen (PSA) progression	Up to 1 year after end of treatment	Time to PSA progression is defined as time from randomization to first PSA progression.; PSA progression is defined as the date that a ≥ 25% increase in PSA and an absolute increase of 2 ng/mL or more from the nadir or baseline is documented and confirmed by a second consecutive value obtained 3 or more weeks later. Rises in PSA within the first 12 weeks will be ignored in the absence of other evidence of disease progression (adapted from Prostate Cancer Working Group (PCWG3) Guidance).
Overall Survival (OS)	Up to 1 year after end of treatment	OS defined as the time from initial treatment until death from any cause.
Change from baseline in FACT-RNT	Baseline, up to 1 year after end of treatment	The FACT-RNT (Functional Assessment of Cancer Therapy - Radionuclide Therapy) is a Patient Reported Outcomes (PRO) new measure developed using FACIT specific questions (items), selected from FACIT item bank, to assess treatment-related symptoms of special interest associated with radioligand therapies.; The FACT-RNT contains items assessing dry mouth, dry eyes, vomiting, diarrhea, constipation, loss of appetite, fatigue, impact of fatigue, bone pain, and isolation due to illness or treatment. FACT-RNT score range 0 to 60, with higher score indicating better quality of life.
Change from baseline in BPI-SF	Baseline, up to 1 year after end of treatment	The BPI-SF is a publicly available instrument to assess the pain and includes severity and interference scores. BPI-SF is an 11-item selfreport questionnaire that is designed to assess the severity and impact of pain on daily functions of a participant. Pain severity score is a mean value for BPI-SF questions 3, 4, 5 and 6 (questions inquiring about the extent of pain, where the extent is ranked from 0 \[no pain\] to 10 \[pain as bad as you can imagine\]). Pain severity progression is defined as an increase in score of 30% or greater from baseline without decrease in analgesic use
Radiographic progression	Up to 1 year after end of treatment	Radiographic progression is measured with radiographic imaging (e.g. CT with contrast/MRI, bone scan, PET/CT, SPECT/CT) according to RECIST/PCWG3
Progression-free survival 2 (PFS2)	Up to 1 year after end of treatment	PFS2, defined as time from initial treatment to the first documented disease progression or death under the treatment after lutetium (177Lu) vipivotide tetraxetan.
Change from baseline in FACT-P	Baseline, up to 1 year after end of treatment	FACT-P assesses symptoms/problems related to prostate carcinoma and its treatment. It is a combination of the FACT- General + the Prostate Cancer Subscale (PCS). The FACTGeneral (FACT-G) is a 27 item Quality of Life (QoL) measure that provides a total score as well as subscale scores: Physical (0-28), Functional (0-28), Social (0-28), and Emotional Well-being (0-24). The total score range is between 1-108, higher scores indicates better for total score and subscale scores. PCS is a 12-item prostate cancer subscale that asks about symptoms and problems specific to prostate cancer (Range 0-48, higher scores better). The FACT-P total score is the sum of all 5 subscale scores of the FACT-P questionnaire and ranges from 0-156. Higher scores indicate higher degree of functioning and better quality of life.
Clinical progression	Up to 1 year after end of treatment	Unequivocal clinical progression (UCP) is considered a worsening of clinical status with or without radiographic progression (RAD): escalation in cancer related-pain, immediate need for initiation of new anticancer treatment, surgical, or radiological intervention, deterioration in ECOG to grade 3 or higher, in the opinion of investigator
Progression-free survival (PFS)	Up to 1 year after end of treatment	PFS, defined as the time from initial treatment to the first documented disease progression or death due to any cause, whichever occurs first.
Functional Assessment of Cancer Therapy-Radionuclid Therapy (FACT-RNT)	Baseline, up to 1 year after end of treatment	The FACT-RNT (Functional Assessment of Cancer Therapy - Radionuclide Therapy) is a Patient Reported Outcomes (PRO) new measure developed using FACIT specific questions (items), selected from FACIT item bank, to assess treatment-related symptoms of special interest associated with radioligand therapies.; The FACT-RNT contains items assessing dry mouth, dry eyes, vomiting, diarrhea, constipation, loss of appetite, fatigue, impact of fatigue, bone pain, and isolation due to illness or treatment. FACT-RNT score range 0 to 60, with higher score indicating better quality of life.
Brief Pain Inventory-Short Form (BPI-SF)	Baseline, up to 1 year after end of treatment	The BPI-SF is a publicly available instrument to assess the pain and includes severity and interference scores. BPI-SF is an 11-item selfreport questionnaire that is designed to assess the severity and impact of pain on daily functions of a participant. Pain severity score is a mean value for BPI-SF questions 3, 4, 5 and 6 (questions inquiring about the extent of pain, where the extent is ranked from 0 \[no pain\] to 10 \[pain as bad as you can imagine\]). Pain severity progression is defined as an increase in score of 30% or greater from baseline without decrease in analgesic use
Prostate-specific antigen (PSA) 30/50/90	Up to 1 year after end of treatment	Response rates are defined as the proportion of patients who have a ≥30%/50%/90% decrease in PSA from baseline that is confirmed by a second PSA measurement.
