Unknown

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

Patients who are diagnosed with acromegaly with a GH-secreting pituitary adenoma receiving TSA at the Asan Medical Center (Seoul, Korea) from Aug 2013 to Aug 2015 will be recruited.

The eligible patient population will consist of 30 adult, male and female patient with Age 18 or older.

  • Number of patients by treatment group: Surgical treatment only = 15, Surgery with medical treatment = 15
  • Number of Centers: 1 (single center)

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Group 2: Surgery + Medical treatment

MRI : residual tumor 6 months post-op : IGF-1 >600 ng/ml

medical treatment : Sandostatin (Octreotide Acetate)
Drug: Sandostatin (Octreotide Acetate)

For the patients outlined above (refer to 2), subjects who are not able to be treated by surgery alone:

  • Dose: Sandostatin LAR® 20mg per 4 weeks for 3 months -> If serum IFG-1 levels fails to normalize, the dose of LAR will be increased to 30 mg.
  • Frequency: every 4 weeks.
  • Route of administration: IM injection.
Other Names:
  • Sandostatin LAR
No Intervention: Group 3 : Rescue group
If IGF-1 levels fails to normalize till post-op 18 months post-op, medical treatment will be added.)
No Intervention: Gruop1 : Surgery only group

MRI : without residual tumor 6months post-operation

and IGF-1 <600ng/ml

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
Number of patients who achieved normalization of fasting serum IGF-1 (age and sex matched)
Time Frame: Change from within 3days post-operative in fasting serum IGF-1at 36 months post-operative
Change from within 3days post-operative in fasting serum IGF-1at 36 months post-operative
The time taken to IGF-1 normalization in each group.
Time Frame: Change from within 3days post-operative in IGF-1 normalization at 36 months post-operative months post-operative
Change from within 3days post-operative in IGF-1 normalization at 36 months post-operative months post-operative

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.
