Capivasertib plus abiraterone in PTEN-deficient metastatic hormone-sensitive prostate cancer: CAPItello-281 phase III study
Open accessAbstract
BACKGROUND: In metastatic hormone-sensitive prostate cancer (mHSPC), phosphatase and tensin homolog (PTEN) deficiency results in phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) pathway activation, providing an independent proliferative drive, which cannot be suppressed by androgen receptor pathway inhibitors (ARPIs), resulting in worse outcomes. Dual inhibition of PI3K/AKT and AR pathways with capivasertib and abiraterone may delay progression and improve disease outcomes. PATIENTS AND METHODS: In CAPItello-281 (NCT04493853), patients with PTEN-deficient mHSPC (diagnostic cut-off: ≥90% viable malignant cells with no specific cytoplasmic PTEN immunohistochemistry staining) received capivasertib or placebo (1 : 1) plus abiraterone, prednisone/prednisolone, and androgen deprivation therapy (ADT). The primary endpoint was investigator-assessed radiographic progression-free survival (rPFS); overall survival (OS) was a key secondary endpoint. Post hoc exploratory subgroups at increasing PTEN cut-off thresholds were also assessed. RESULTS: 25.3% (1519/6003) of patients with valid tumor test results had PTEN-deficient tumors. In the randomized PTEN-deficient population, a statistically significant improvement in rPFS was observed with capivasertib plus abiraterone (n = 507, median 33.2 months) versus placebo plus abiraterone [n = 505, 25.7 months; hazard ratio (HR) 0.81, 95% confidence interval (CI) 0.66-0.98, P = 0.034]. Post hoc rPFS analyses for loss of PTEN cut-offs of ≥95%, ≥99%, and 100% showed that the capivasertib plus abiraterone arm performed consistently across cut-offs, but the placebo plus abiraterone arm performed progressively worse as the cut-off for the degree of PTEN loss was increased, resulting in a numerically improved treatment effect. In the overall population studied, the HR for OS (26.4% maturity) was 0.90, 95% CI 0.71-1.15, P = 0.401. The most common adverse events (AEs) for capivasertib plus abiraterone were diarrhea (51.9%; 8.0% placebo plus abiraterone), hyperglycemia (38.0%; 12.9%), and rash (35.4%; 7.0%). Deaths associated with an AE were reported in 36 (7.2%) and 26 (5.2%) patients in the capivasertib plus abiraterone and placebo plus abiraterone arms, respectively. CONCLUSIONS: Capivasertib plus abiraterone improves rPFS versus placebo plus abiraterone in PTEN-deficient mHSPC, on a background of ADT, with a 7.5-month improvement in median rPFS. AE profile was consistent with that of the individual agents. Patients with PTEN-deficient mHSPC benefit from dual blockade of the PI3K/AKT and AR pathways with capivasertib plus abiraterone.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
