Capivasertib + Abiraterone for Prostate Cancer (CAPItello-281 Trial)

Phase 3
Waitlist Available
Research Sponsored by AstraZeneca
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Provide a FFPE tissue block (preferred) or slides. Tissue from bone metastases is not acceptable
Able and willing to swallow and retain oral medication
Must not have
Inadequate bone marrow reserve or organ function as demonstrated by any of the following laboratory values: i. Absolute neutrophil count < 1.5x 109/L ii. Platelet count < 100x 109/L iii. Haemoglobin < 9 g/dL (< 5.59 mmol/L) iv. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) > 2.5x upper limit of normal (ULN) if no demonstrable liver metastases or > 5x ULN in the presence of liver metastases. Elevated alkaline phosphatase (ALP) is not exclusionary if due to the presence of bone metastases and liver function is otherwise considered adequate in the investigator's judgement v. Total bilirubin > 1.5x ULN (participants with confirmed Gilbert's syndrome may be included in the study with a higher value) vi. Creatinine clearance < 50 mL/min (measured or calculated by Cockcroft and Gault equation)
Refractory nausea and vomiting, malabsorption syndrome, chronic gastrointestinal diseases, inability to swallow the formulated product or previous significant bowel resection, or other condition that would preclude adequate absorption of capivasertib
Timeline
Screening 3 weeks

Summary

This trial will compare the efficacy of capivasertib+abiraterone+androgen deprivation therapy to placebo+abiraterone+androgen deprivation therapy in men with metastatic hormone-sensitive prostate cancer (mHSPC) whose tumours are PTEN-deficient. The primary endpoint is radiographic progression-free survival.

Who is the study for?
Men with metastatic hormone-sensitive prostate cancer and PTEN deficiency, who can take abiraterone and steroids, are eligible. They must have a recent diagnosis (within 180 days), provide specific tissue samples, show evidence of metastasis, be on ADT treatment for up to 93 days before the trial starts, have an ECOG performance status of 0-1, and agree to contraception. Exclusions include brain metastases or spinal cord compression not stable without steroids for at least four weeks.
What is being tested?
The study is testing if adding Capivasertib to Abiraterone (+prednisone/prednisolone) along with ADT provides better outcomes than placebo plus Abiraterone (+prednisone/prednisolone) with ADT in men whose tumors lack PTEN protein. The main goal is improving time without disease progression using imaging criteria or until death from any cause.
What are the potential side effects?
Possible side effects may include nausea, vomiting issues due to medication absorption problems; lung conditions like interstitial lung disease; heart-related issues such as QT interval prolongation or heart failure; uncontrolled high blood pressure; significant abnormalities in glucose metabolism requiring insulin treatment.
