About this study
Official title: SPECIAL INVESTIGATION OF SOMAVERT -LONG TERM USE-
The objective of this surveillance is to collect information about 1) adverse drug reaction not expected from the LPD (unknown adverse drug reaction), 2) the incidence of adverse drug reactions in this surveillance, and 3)factors considered to affect the safety and/or efficacy of this drug.
Read the detailed description
All the patients whom an investigator prescribes the first Somavert (Pegvisomant) should be registered consecutively until the number of subjects reaches target number in order to extract patients enrolled into the investigation at random.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Treatment-Related Adverse Events
A treatment-related adverse event was any untoward medical occurrence attributed to Somavert in a participant who received Somavert. A treatment-related serious adverse event was a treatment-related adverse event resulting in any of the following outcomes or deemed significant for any other reason: death; life-threatening experience (immediate risk of dying); initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly. Relatedness to Somavert was assessed by the physician.
Measured: 5 years
Number of Participants With Treatment-Related Adverse Events Unexpected From Japanese Package Insert
A treatment-related adverse event was any untoward medical occurrence attributed to Somavert in a participant who received Somavert. Expectedness of the adverse event was determined according to the Japanese package insert. Relatedness to Somavert was assessed by the physician.
Measured: 5 years
Number of Participants With Treatment-Related Adverse Events by Gender
A treatment-related adverse event was any untoward medical occurrence attributed to Somavert in a participant who received Somavert. Relatedness to Somavert was assessed by the physician. Participants with treatment-related adverse events were counted by gender to assess whether it was a risk factor for the occurrence of treatment-related adverse events.
Measured: 5 years
Number of Participants With Treatment-Related Adverse Events by Age
A treatment-related adverse event was any untoward medical occurrence attributed to Somavert in a participant who received Somavert. Relatedness to Somavert was assessed by the physician. Participants with treatment-related adverse events were counted by age to assess whether it was a risk factor for the occurrence of treatment-related adverse events.
Measured: 5 years
Number of Participants With Treatment-Related Adverse Events for Participants With Hepatic Function Disorder
A treatment-related adverse event was any untoward medical occurrence attributed to Somavert in a participant who received Somavert. Relatedness to Somavert was assessed by the physician. Participants with treatment-related adverse events were counted by hepatic function disorder to assess whether it was a risk factor for the occurrence of treatment-related adverse events.
Measured: 5 years
Number of Participants With Treatment-Related Adverse Events for Participants With Renal Impairment
A treatment-related adverse event was any untoward medical occurrence attributed to Somavert in a participant who received Somavert. Relatedness to Somavert was assessed by the physician. Participants with treatment-related adverse events were counted by renal impairment to assess whether it was a risk factor for the occurrence of treatment-related adverse events.
Measured: 5 years
Number of Participants With Treatment-Related Adverse Events for Participants With Diabetes Mellitus (Concurrent Disease)
A treatment-related adverse event was any untoward medical occurrence attributed to Somavert in a participant who received Somavert. Relatedness to Somavert was assessed by the physician. Participants with treatment-related adverse events were counted by diabetes mellitus (concurrent disease) to assess whether it was a risk factor for the occurrence of treatment-related adverse events.
Measured: 5 years
Clinical Effectiveness Rate
Clinical effectiveness rate, which was defined as the percentage of participants who achieved clinical effectiveness over the total number of assessable effectiveness analysis population, was presented. Clinical effectiveness of Somavert was assessed as "effective," "ineffective" or "unassessable" by the physician. Overall effectiveness of Somavert was determined by the physician based on clinical symptoms, laboratory values, and other examinations such as ring size.
Measured: 5 years
Clinical Effectiveness Rate by Gender
Clinical effectiveness rate, which was defined as the percentage of participants who achieved clinical effectiveness over the total number of assessable effectiveness analysis population, was presented. Clinical effectiveness of Somavert was assessed as "effective," "ineffective" or "unassessable" by the physician. Overall effectiveness of Somavert was determined by the physician based on clinical symptoms, laboratory values, and other examinations such as ring size. Participants achieved clinical effectiveness by gender were counted to assess whether it contributes to the clinical effectiveness.
Measured: 5 years
Clinical Effectiveness Rate by Age
Clinical effectiveness rate, which was defined as the percentage of participants who achieved clinical effectiveness over the total number of assessable effectiveness analysis population, was presented. Clinical effectiveness of Somavert was assessed as "effective," "ineffective" or "unassessable" by the physician.

The record says: finished, as of the sponsor's last update on 25 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 22 Jan 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Treatment-Related Adverse Events (time frame: 5 years). The study lists 12 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2023.
