Abstract

Background/objectives: Based on the SPARTAN and TITAN studies, apalutamide is approved for patients with nonmetastatic castration-resistant and metastatic castration-sensitive prostate cancer. Skin rash was a common adverse reaction across indications. We hypothesized that earlier identification and intervention could improve rash outcomes.

Subjects/methods: A prespecified rash management guide outlining recommended skin care practices was provided to all patients enrolled in Apa-RP (NCT04523207). Rash-related safety data from Apa-RP were compared descriptively with data from SPARTAN and TITAN.

Results: Patients in Apa-RP experienced improved rash-related outcomes vs those in SPARTAN and TITAN.

Conclusions: Increased vigilance and proactive management may reduce the incidence, severity, and duration of rash during apalutamide treatment.
