A study to a) evaluate the tolerability and blood levels of KVD900 when given as a single dose to patients and b) to assess whether KVD900 is effective in treating attacks of swelling in patients with the genetic disease, Hereditary Angioedema.

A randomized, double-blind, placebo-controlled, phase II, cross-over clinical trial evaluating the efficacy and safety of KVD900, an oral plasma kallikrein inhibitor, in the on-demand treatment of angioedema attacks in adult subjects with hereditary angioedema type I or II

Inclusion criteria

Inclusion criteria: 1. Male or female adult subjects 18 years of age and older. 2. Confirmed diagnosis of HAE type I or II at anytime in the medical history 3. At least 3 documented HAE attacks in the past 93 days, as supported by medical history. 4. Access to and ability to use conventional attack treatment for attacks of HAE. 5. Adequate organ functions as defined below: a. Hemoglobin within normal range; b. International normalized ratio (INR)=65 years) yes F.1.3.1 Number of subjects for this age range 5

Exclusion criteria

Exclusion criteria: 1. Any concomitant diagnosis of another form of chronic angioedema. 2. Current use of C1INH, androgens, or tranexamic acid for HAE prophylaxis. 3. Use of angiotensin-converting enzyme (ACE) inhibitors or any estrogen-containing medications with systemic absorption within 90 days prior to initial study treatment. 4. Use of androgens or antifibrinolytics within 90 days prior to initial study treatment. 5. Use of strong CYP3A4/CYP2C9 inhibitors and inducers during participation in the trial. 6. Clinically significant abnormal electrocardiogram (ECG) at Visit 1 and pre-dose at Visit 2. 7. Any clinically significant history of angina, myocardial infarction, syncope, clinically significant cardiac arrhythmias, left ventricular hypertrophy, cardiomyopathy, or any other cardiovascular abnormality. 8. Any other systemic dysfunction (e.g., gastrointestinal, renal, respiratory, cardiovascular) or significant disease or disorder which, in the opinion of the Investigator, would jeopardize the safety of the subject by taking part in the trial. 9. History of substance abuse or dependence that would interfere with the completion of the study, as determined by the Investigator. 10. Known lactose allergy or intolerance. 11. Known hypersensitivity to KVD900 or placebo or to any of the excipients. 12.

Any pregnant or breast-feeding subject

Design outcomes

Primary

MeasureTime frame
Main Objective: To investigate the efficacy of KVD900 compared to placebo in halting the progression of attacks of HAE. ;Secondary Objective: To investigate the safety and tolerability of KVD900 To investigate the pharmacokinetic (PK) profile of KVD900 To investigate the pharmacodynamic (PD) profile of KVD900;Primary end point(s): Primary Efficacy Endpoints: • Time to use of conventional attack treatment. ;Timepoint(s) of evaluation of this end point: 12 hours

Secondary

MeasureTime frame
Secondary end point(s): Secondary Efficacy Endpoints: • Proportion of HAE attacks that progress by one level or more on the 5LS or that require conventional attack treatment within 12h of study drug. • Time between treatment and (1) progression of global attack severity on the 5LS by one level or more, or (2) use of conventional attack treatment, whichever comes first within 12h;Timepoint(s) of evaluation of this end point: 12 hours
