Patient case: 81-year-old male with Prostate cancer. Genetic variant: PTEN Inactivating. Other conditions: Hypertension, Depression.

Clinical trial: Efficacy Study of Methylphenidate Hydrochloride to Reduce Fatigue in Prostate Cancer Patients Receiving Hormone Therapy

Summary: The purpose of this study is to determine if methylphenidate improves fatigue in men undergoing hormonal therapy for prostate cancer with an LHRH-agonist.

Detailed description: This study will determine if methylphenidate improves fatigue in men undergoing hormonal therapy for prostate cancer. Fatigue is a common problem experienced by cancer patients. Those patients who are receiving chemotherapy or radiation are especially vulnerable to fatigue, as are men with prostate cancer who are receiving hormonal therapy with an LHRH-agonist (androgen deprivation therapy). Eligible men will be randomized to a daily dose of 10 mg methylphenidate or placebo for a total treatment period of 12 weeks. Subjects will be monitored for changes in fatigue and mood during this period. While the exact cause of fatigue in this setting is unknown, this study will hopefully lead to a better understanding of the process and provide patients with a much-needed remedy for fatigue

Eligibility: Inclusion:
  -  Age > 18 and ≤ 85 years

  -  Deemed eligible to commence LHRH-agonist therapy, with confirmation of fatigue at Screening Visit 2
  -  Have a serum PSA which is stable or decreasing based on the PSA trend over the last 2 values taken at least 2 months apart, with the more recent value taken at least 2 months after initiation of LHRH-agonist therapy.
