Brief Summary:
The goal of this clinical trial is to test the drug STAR-0215 in participants with hereditary angioedema (HAE). One group of participants will get 1 dose of STAR-0215, and two other groups will get 2 doses of STAR-0215. Researchers will study the effects of STAR-0215 in participants with HAE as this is the first time that the drug has been given to participants with HAE.

Condition or disease Intervention/treatment Phase
Hereditary Angioedema Drug: STAR-0215 Phase 1 Phase 2

Detailed Description:
This is a Phase 1b/2 single and multiple dose trial evaluating the safety, tolerability, clinical activity, pharmacokinetics, pharmacodynamics, and immunogenicity of subcutaneous administration of STAR-0215 in participants with type I or type II HAE in 3 dose cohorts. The first cohort will receive 1 dose of STAR-0215; the second and third cohorts will receive 2 sequential doses. This is the first trial of STAR-0215 in participants with HAE and the first evaluation of a multiple-dose regimen.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Participants Experiencing Treatment-emergent Adverse Events [ Time Frame: Day 1 through Day 168 (Cohort 1), Day 251 (Cohort 2), and Day 195 (Cohort 3) ]

Secondary Outcome Measures :
  1. Change From Baseline in Monthly HAE Attack Rate [ Time Frame: Baseline through Day 168 (Cohort 1), Day 251 (Cohort 2), and Day 195 (Cohort 3) ]
  2. Severity of HAE Attacks Experienced by Participants [ Time Frame: Cohort 1: Day 1 through Day 168; Cohort 2: Day 1 through Day 251; Cohort 3: Day 1 through Day 195 ]
    All HAE attacks will be classified according to severity (mild, moderate, and severe).

  3. Duration of HAE Attacks [ Time Frame: Cohort 1: Day 1 through Day 168; Cohort 2: Day 1 through Day 251; Cohort 3: Day 1 through Day 195 ]
    Duration will be reported as shorter than 12 hours, 12 to 24 hours, 24 to 48 hours, and longer than 48 hours.

  4. Number of Participants Experiencing HAE Attacks Requiring On-demand Therapy [ Time Frame: Cohort 1: Day 1 through Day 168; Cohort 2: Day 1 through Day 251; Cohort 3: Day 1 through Day 195 ]
  5. Time to First HAE Attack After First and Last Dosing [ Time Frame: Cohort 1: Day 1 through Day 168; Cohort 2: Day 1 through Day 251; Cohort 3: Day 1 through Day 195 ]
  6. Serum Concentration of STAR-0215 [ Time Frame: Cohort 1: Day 1 (pre-dose, 4 hours post dose) up to Day 168; Cohort 2: Days 1 and 84 (pre-dose, 4 hours post dose) up to Day 251; Cohort 3: Days 1 and 28 (pre-dose, 4 hours post dose) up to Day 195 ]
    Blood samples will be collected to measure the serum concentration of STAR-0215 before and after study drug administration.

  7. Plasma Levels of Cleaved High-molecular-weight Kininogen [ Time Frame: Cohort 1: Day 1 (pre-dose, 4 hours post dose) up to Day 168; Cohort 2: Days 1 and 84 (pre-dose, 4 hours post dose) up to Day 251; Cohort 3: Days 1 and 28 (pre-dose, 4 hours post dose) up to Day 195 ]
    Blood samples will be collected to measure the plasma levels of cleaved high-molecular-weight kininogen (a measure of plasma kallikrein activity).

  8. Number of Participants with Anti-drug Antibodies To STAR-0215 [ Time Frame: Cohort 1: Day 1 (pre-dose); Days 14, 28, 56, 84, 112, 140, and 168; Cohort 2: Days 1 and 84 (pre-dose); Days 14, 28, 56, 111, 167, and 251; Cohort 3: Days 1 and 28 (pre-dose); Days 14, 55, 111, and 195 ]
    Blood samples will be collected to assess the formation of STAR-0215 anti-drug antibodies in serum before and after study drug administration.
