An External Control Arm Study Comparing Survival Among Metastatic Castration-Resistant Prostate Cancer (mCRPC) Patients Treated With 177Lu-PSMA-617 vs Androgen Receptor Pathway Inhibitor (ARPI) Switch in Routine Care
Comparing the Lutetium (177Lu) Vipivotide Tetraxetan Arm of the PSMAfore Clinical Trial to a Switch in Androgen Receptor Pathway Inhibitor (ARPI) as External Control Arm (ECA) Using a Real-world Data Source for Patients With Metastatic Castration-Resistant Prostate Cancer (mCRPC) After Progression on Prior ARPI
The aim of this study is to assess the effectiveness of 177Lu-PSMA-617 (lutetium (177Lu) vipivotide tetraxetan) on survival in patients randomized to receive treatment following progression on one ARPI from the PSMAfore trial compared to the effectiveness of a change in ARPI treatment on survival in a real-world setting in patients with mCRPC who are taxane-naive but have progressed after a switch in ARPI.

Studiebefolkning
PSMAfore trial patients with mCRPC who progressed once after treatment with an ARPI and were taxane-naive, and real-world data (RWD) mCRPC patients from the United States (US)-based health research database who were taxane-naive and had evidence of treatment with a change in ARPI immediately following progression.
Beskrivelse
Inclusion criteria:
- Had an International Classification of Diseases, 9th or 10th Revision, Clinical Modification (ICD-9-CM or ICD-10-CM) diagnosis of prostate cancer (PC) (ICD-9-CM 185x or ICD-10-CM C61x).
- Had at least two documented clinical visits, on different days, occurring on or after 01 Jan 2013.
- Included in probabilistic sample of patients queued for review via abstraction.
- Had diagnosis of metastatic disease on or after 01 Jan 2013.
- Histology was confirmed as adenocarcinoma of the prostate.
- Had confirmed mCRPC diagnosis.
- Treated with an ARPI-containing line of therapy (LOT; i.e., index therapy) in the mCRPC setting immediately after progression on one previous ARPI-containing line (in any setting, Hormone Sensitive PC or castration-resistant PC), as defined per the health research database's LOT rules and confirmed via abstraction.
- 18 years of age or older at the start of index therapy.
- Had an Eastern Cooperative Oncology Group Performance Score (ECOG PS) of 0-1 within 30 days before or up to 7 days after index date, or unknown ECOG PS.
Exclusion criteria:
- Female sex.
- Had evidence of untreated brain metastases.
- Had history of cardiac comorbidities, infection with hepatitis B or C, or spinal cord compression that would indicate significant risk to PSMAfore trial participation.
- Diagnosis of an active additional malignancy (i.e., other than prostate cancer).
- Evidence of biomarker status that would indicate eligibility for treatment other than ARPI, or better prognosis.
- Evidence of prior treatment with therapies that potentially affect study outcomes (e.g., radiopharmaceuticals, taxane, immunotherapy or biological therapy, clinical study drug (CSD), or 177Lu-PSMA-617).
- Had evidence of inadequate organ function.
- Had evidence of low levels of albumin (< 2.5 g/dL).
- Had evidence of a negative PSMA-PET scan.
Other protocol-defined inclusion/exclusion criteria may apply.
