A Study to Test a Measure of Symptoms of Older Men With Low Testosterone On and Off Testosterone Replacement Treatment (P05815)

• Status: Terminated
• Trial end date: 2007-01-01
• Target enrollment: 0
• Participant gender: Male

Summary

Hypogonadal males, particularly those whose condition manifested later in life, may experience common symptoms associated with their hypogonadism. Questionnaires developed to assess these symptoms need to be tested. The primary purpose of this study is to test or validate the Patient-Reported Symptom Measure, Androgen Deficiency Quality of Life Questionnaire and the Patient Global Impression Scale.

• Phase: Phase 2
• Accepts Healthy Volunteers?: Accepts Healthy Volunteers

Details

• Lead Sponsor: Merck Sharp & Dohme Corp.
• Treatments: Methyltestosterone; Testosterone; Testosterone 17 beta-cypionate; Testosterone enanthate; Testosterone undecanoate

Criteria

Inclusion Criteria:

Men with late-onset hypogonadism who are either on testosterone treatment or naïve of treatment:

• have symptoms of androgen deficiency at screening (after wash-out if applicable) i.e. with a positive score on the Androgen Deficiency in the Aging Male (ADAM) Questionnaire (a "yes" answer to questions 1 or 7 or any three other questions).

• morning total T levels of <=3 ng/mL (<=300 ng/dL; <=10.4 nmol/l) on two separate days prior to randomization (after appropriate wash-out, if applicable).

• calculated free T <=0.074 ng/mL.

• at least 50 and at most 75 years of age.

• BMI of at least 18 kg/m^2 or at most 32 kg/m^2

Inclusion Criteria for Normogonadal Men:

• morning total T levels <=3 ng/mL (<=300 ng/dL; <=10.4 nmol/L).

• calculated free T <=0.074 ng/mL.

• at least 50 and at most 75 years of age.

• BMI of at least 18 kg/m^2 or at most 32 kg/m^2

Exclusion Criteria:

• History or current diagnosis of prostate cancer or any clinically significant finding on prostate examination

• Severe obstructive symptoms of benign prostate hypertrophy

• Prostate specific antigen (PSA) levels greater than 4 ng/mL at screening

• History or current diagnosis of carcinoma of the breast

• Known chronic polycythemia and/or hematocrit greater than 50% at screening

• Treatment-naïve subjects with hyperprolactinemia at screening (serum prolactin level >=50 ng/mL)

• Hematological or biochemical values at screening outside the reference ranges considered as clinically significant in the opinion of the investigator

• clinically significant abnormal physical finding prior to randomization

• sensitive to trial medication or its components

• History or presence of hepatic or renal disorder considered as clinically relevant in the opinion of the investigator.

Exclusion Criteria for Normogonadal Men:

• Presence or previous diagnosis of androgen deficiency.

• Previous or present use of testosterone preparations

• Use of medication within the 12 weeks prior to the visit that may interfere with the objectives of the trial: hypothalamic/pituitary hormones and analogues (e.g., gonadotropins, ACTH, STH, Gn-RH agonists and antagonists, etc.); sex steroid

• Any other disease that in the opinion of the investigator might compromise or confound the subject's symptomatology (e.g., presence of clinically significant depression or other psychiatric disorders, unstable endocrine disorder, sleep apnea, cardiovascular and cerebrovascular diseases, etc.)
