Early Identification and Management of Patients with Rash on Apalutamide.

ABSTRACT

Apalutamide is a selective androgen receptor signalling inhibitor that is used in the treatment of prostate cancer. Skin rash is one of the most common adverse events with apalutamide. Although the majority of rash events are grade 1 and 2, the appearance of skin rash during treatment can lead to dose reduction, a pause in treatment or even treatment discontinuation, especially if patients present late when the rash has become severe. This in turn can result in a significant delay or even a permanent discontinuation in the patient's treatment of prostate cancer. As apalutamide is a generally well tolerated and an effective treatment for many men with advanced prostate cancer, it is extremely important to make attempts to prevent skin problems or to manage them at the earliest stage possible. We therefore have developed practical guidance for the management of apalutamide-related rash, including an infographic with recommendations for rash management by grade. Central to this approach is patient education and awareness. Encouraging patients to proactively care for their skin from the start of treatment and informing them of the risk of rash with apalutamide therapy are essential. If the patient observes any skin changes, they should be advised to report it straight away to their cancer care team. Adopting this simple, proactive approach of patient education and increased vigilance from the care team is expected to lead to early identification of rash and subsequent intervention to allow for quicker resolution and enable patients to continue their cancer treatment with a drug that can delay disease progression and increase survival in patients with prostate cancer.
