Time to Onset of Symptom Relief (TOSR) for Composite Investigator-Assessed Symptom Scores for Icatibant Exposure Number 1 | |||||||||||||||
End point description |
TOSR was defined as the duration of time in hours from study drug administration to the earliest time post-treatment at which there was at least a 20 percent(%) improvement in the average post-treatment symptom score with no worsening of any single component score for the initial icatibant exposure. The investigator used a symptom score to assess the severities of symptoms of acute cutaneous, abdominal, and laryngeal attacks of HAE using the following 5-point scale: 0=none, 1=mild, 2=moderate, 3=severe and 4=very severe. TOSR for subjects received initial icatibant administration was reported. In the below table, number of subjects analyzed indicates the subjects evaluable for this endpoint.

Rescue medication was any medication used after the administration of icatibant which, in the opinion of the investigator, was immediately necessary to alleviate acute symptoms which are judged by the investigator as resultant from the current HAE attack. Time to first use of rescue medication prior to the onset of symptom relief was calculated from the time of study drug administration to the first use of rescue medication prior to the onset of symptom relief. This analysis was not performed since as per protocol, "This analysis will only be performed if there are at least 5 subjects for a given attack who used rescue medication prior to attaining symptom relief". In the below table, the number of subjects analyzed signifies subjects who were evaluable for this measure.

05 Aug 2011 |
- Safety assessments were amended to include ECG evaluations.
- An investigator assessment utilizing a comportmental pain scale (FLACC) was added for the evaluation of abdominal symptoms of acute HAE in children below 4 years of age. |
||
06 Mar 2012 |
- Determination of Tanner stage was eliminated in favor of simply stratifying subjects by pubertal status.
- Clarifications were made to inclusion criterion pertaining to the definition of C1-INH deficiency.
- Clarification to exclusion criterion was made to ensure that the text clearly prohibits subjects from participating in another concurrent interventional clinical study and to exclude subjects with a physical condition that interfered with pubertal status determination. |
||
19 Jun 2013 |
- The number of adolescent subjects participating in the study remained at 20; however, 10 subjects were to be treated with icatibant during an HAE attack while the other 10 subjects were to be treated without an attack.
- The number of prepubertal subjects was reduced from 16 to 10.
- Adolescent subjects, including both those treated during an attack or not, could be offered further open-label treatment with icatibant for any subsequent HAE attacks that occurred at least 7 days after prior treatment. |
||
18 Mar 2016 |
- A parent/legal guardian/caregiver was allowed to administer or the subject (under the supervision of a parent/legal guardian/caregiver) was allowed to self-administer the investigational product after having received appropriate training. |
