Conditions

Small for Gestational Age

Brief summary

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.

Detailed description

All the patients whom an investigator prescribes the first Genotropin® should be registered consecutively until the number of subjects reaches target number in order to extract patients enrolled into the investigation at random.

Interventions

DRUGSomatropin

Genotropin® 5.3mg, Genotropin®inj.12mg, Genotropin®MiniQuick s.c. inj.0.6mg・1.0mg・1.4mg, depending on the Investigator prescription. Frequency and duration are according to Package Insert as follows. Normally, the dosage is 0.021 mg/kg/week as somatropin (genetical recombination) in 6-7 divided doses by s.c. route. If efficacy is insufficient, the dose may be increased up to 0.47 mg/kg/week in 6-7 divided doses in a week by s.c. route.

Number of Participants With Treatment Related Adverse Events.Up to 3 yearsAdverse events mean all unfavorable events that occur in participants after administration of somatropin, irrespective of causal relationship to somatropin (including clinically problematic abnormal changes in laboratory test values). Treatment related adverse events were evaluated in company with the causal relationship to somatropin.
Number of Unlisted Treatment Related Adverse Events According to Japanese Package Insert.Up to 3 yearsAdverse events mean all unfavorable events that occur in participants after administration of somatropin, irrespective of causal relationship to somatropin (including clinically problematic abnormal changes in laboratory test values).

Change in the Growth Rate Standard Deviation (SD) Score for Calendar Age.Up to 3 yearsGrowth rate SD score = (Growth rate - Average growth rate for calendar age of gender) / SD score for growth rate for each calendar age of gender). An SD score indicates how far a participant's score deviates from the mean of the reference population; an SD score higher than the mean gives a positive SD score whereas an SD score lower than the mean gives a negative SD score. In addition, when the bone age was described, it was to be read as the calendar age for men who were 11 years or older and women who were 9 years or older, as necessary.
Change in Height SD Score for Calendar Age.Up to 3 yearsThe change in height standard SD for calendar age = (Height SD score for each calendar age - Height SD score for calendar age of the previous year) / (the date on which the height was measured - the date of the previous year on which the height was measured) × 365.25.

Outcome results

Primary

Change in Height SD Score for Calendar Age.

The change in height standard SD for calendar age = (Height SD score for each calendar age - Height SD score for calendar age of the previous year) / (the date on which the height was measured - the date of the previous year on which the height was measured) × 365.25.

Time frame: Up to 3 years

Population: The efficacy analysis population basically consists of the evaluable participants in whom the changes in the growth rate SD score for calendar age and in the height SD score for calendar age were assessed.
