Monitoring

  • CBC w diff, CMP (baseline and every 3 months thereafter).
  • PSA every 3 months or as clinically indicated.
  • Monitor thyroid function (e.g., thyroid-stimulating hormone [TSH]) as clinically necessary (TSH was monitored at baseline and every 4 months in studies).
  • Monitor for signs/symptoms of cardiovascular events, seizure, and dermatologic toxicity and assess for fall and fracture risk.

Mechanism of Action

Apalutamide is a nonsteroidal androgen receptor inhibitor; apalutamide binds directly to the androgen receptor ligand-binding domain to prevent androgen-receptor translocation, DNA binding, and receptor-mediated transcription.

In layman’s terms: This medication is an anti-androgen (anti-testosterone). When testosterone binds to an androgen receptor, it causes the tumor cells to grow. You are taking this medication to block the effects of testosterone by slowing down the growth and spread of prostate cancer. As a result, the prostate tumor may stop growing, and the cancer cells die.
