Current Primary Outcome Measures ICMJE |
Time-normalized Number of HAE Attacks (Per Month) From Week 1 to Week 17 [ Time Frame: Week 1 to Week 17 ] The Week 1 to end of on-treatment period HAE attack rate was calculated for each participant as number of HAE attacks occurring from Week 1 to 28 days after the last dose date divided by the number of days the participant contributed to the 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).

Official Title ICMJE | A Randomized, Double-Blind, Placebo-Controlled, Phase 2a Study to Assess the Clinical Efficacy of ISIS 721744, a Second-Generation Ligand-Conjugated Antisense Inhibitor of Prekallikrein, in Patients With Hereditary Angioedema | ||||||
Brief Summary | The purpose of this study was to evaluate the clinical efficacy, safety, and tolerability of donidalorsen in participants with hereditary angioedema (HAE) type 1 (HAE-1), HAE type 2 (HAE-2), or HAE with normal C1-inhibitor (C1-INH) and to evaluate the effect of donidalorsen on plasma prekallikrein (PKK) and other relevant biomarkers. | ||||||
Detailed Description | This was a randomized, double-blind, placebo-controlled study in 23 participants conducted concurrently in 2 parts (Part A and Part B); participants were allocated into Part A or Part B according to type of HAE (i.e., either HAE-1/HAE-2 in Part A or HAE-nC1-INH in Part B). Part A was randomized, double-blind, and placebo-controlled; and Part B was open-label. The length of participation in the study was approximately 8 months, which included an up to 8-week screening period, a 12-week treatment period, and a 13-week post-treatment period. | ||||||
