Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Androgen deprivation therapy is the mainstay of treatment for advanced prostate cancer. There is an increasing tendency towards earlier treatment with hormone manipulation. However, luteinizing hormone-releasing agonists decrease serum testosterone to castrate levels within two weeks of commencement.They are associated with loss of libido, loss of muscle bulk and accelerated bone loss. Osteoporotic patients are at high risk of fragility fractures. An alternative is the nonsteroidal antiandrogen bicalutamide which blocks testosterone at the receptor level, allowing androgen deprivation in the prostate without reducing circulating levels of testosterone. This should preserve the desired effects on other androgen-sensitive tissue, resulting in an advantageous side effect profile. The aim of our study is to closely monitor osteoporotic patients commencing bicalutamide for a period of 12 months. Patients will be reviewed in a dedicated prostate cancer clinic every 3 months. Patients will be questioned regarding adverse events. Renal and liver function tests, prostate specific antigen, testosterone, estradiol and bone turnover markers will be measured 3 monthly. Measurement of height , weight, body mass index, quadriceps strength using dynamometry, and skeletal mass using arm anthropometry (mid-arm circumference and triceps skinfold thickness), will be carried out 3 monthly. Quality of life issues will be assessed 3 monthly using the Rand 36-Item Health Survey (SF36) and University of California-Los Angeles Prostate Cancer Index (UCLAPCI). Patients will undergo bone densitometry of the forearm at baseline and 12 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Quality of life (using Rand 36-Item Health Survey SF-36)
Time Frame: 3 monthly for 1 year
3 monthly for 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Renal & liver function tests, PSA, testosterone, estradiol
Time Frame: 3 monthly for 1 year
3 monthly for 1 year
