研究概览
详细说明
这是一项针对多达 24 名 HAE 参与者的 Donidalorsen 的开放标签扩展研究。
参与研究的时间约为 68 周,其中包括长达 4 周的资格鉴定期、52 周的治疗期和 12 周的治疗后期。
在第 53 周的治疗期访问之后,参与者将可以选择在长达 104 周的延长治疗期内接受 Donidalorsen。

实验性的:HAE-1/HAE-2
Participants with hereditary angioedema Type I/Type II (HAE-1/HAE-2) who received placebo or donidalorsen, 80 milligrams (mg), SC once every 4 weeks, in the previous study ISIS 721744-CS2 (NCT04030598), received donidalorsen, 80 mg, SC once every 4 weeks, from Week 1 to Week 13 (Fixed Dosing Period).
Starting From Week 17 (Flexible Dosing Period), participants had 3 different dosing options as: 80 mg every 4 weeks, 80 mg every 8 weeks for participants who were attack-free for ≥12 weeks, 100 mg every 4 weeks for participants who were not attack-free for ≥12 weeks up to Week 53 based on the investigator and sponsor medical monitor recommendation.
Participants continued flexible dosing from Week 53 for up to approximately 209 weeks.

实验性的:HAE-nC1-INH
Participants with hereditary angioedema with normal C1-inhibitor (HAE-nC1-INH) who received donidalorsen, 80 mg, SC, once every 4 weeks, in the previous study ISIS 721744-CS2 (NCT04030598), continued to receive donidalorsen, 80 mg, SC once every 4 weeks, from Week 1 to Week 13 (Fixed Dosing Period).
Starting From Week 17 (Flexible Dosing Period), participants had 2 different dosing options as: 80 mg every 4 weeks, and 100 mg every 4 weeks for participants who were not attack-free for ≥12 weeks up to Week 53 based on the investigator and sponsor medical monitor recommendation.
Participants continued flexible dosing from Week 53 for up to approximately 209 weeks.

Percentage of Participants With Treatment-emergent Adverse Events (TEAEs)
大体时间:Up to Week 221
|
An adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not the AE is considered related to the medicinal (investigational) product.
TEAEs were defined as those AEs that either started or worsened in severity on or after the date/time of first administration of study drug in this OLE Study.
TEAEs included both serious and non-serious TEAEs.
|
Up to Week 221

|
Percentage of Participants With Clinically Meaningful Changes in Clinical Laboratory Assessments
大体时间:Up to Week 221
|
Clinical laboratory tests including clinical chemistry, hematology, coagulation, complement, inflammatory, urinalysis were performed.

|
|
Percentage of Participants With Clinically Meaningful Changes in Vital Signs

Percent Change From Baseline in Time-normalized HAE Attack (Per 4 Weeks) Rate
大体时间:Up to Week 221
|
HAE attack rate was calculated for each participant as the number of HAE attacks occurring during the respective period divided by the number of days the participant contributed to this period multiplied by 28 days.
An HAE attack was defined as an event with signs or symptoms consistent with an attack in at least 1 of the locations: peripheral angioedema (cutaneous swelling involving an extremity, the face, neck, torso, and/or genitourinary region), abdominal angioedema (abdominal pain, with or without abdominal distention, nausea, vomiting, or diarrhea), laryngeal angioedema (stridor, dyspnea, difficulty speaking, difficulty swallowing, throat tightening, or swelling of the tongue, palate, uvula, or larynx).
A negative change from baseline in HAE attacks indicates an improvement in HAE attacks.

Up to Week 221

|
Percentage of Participants Who Used On-demand Medications
大体时间:Up to Week 221
|
The most commonly used on-demand medications during the On-Treatment Period were C1 esterase inhibitors (human) and icatibant, which were allowed per-protocol for treatment of acute attacks.
