Study of BCX7353 as a Treatment for Attacks of Hereditary Angioedema

Hereditary Angioedema (HAE)

This 3-part study will evaluate the efficacy and safety of an oral kallikrein inhibitor, BCX7353, in the treatment angioedema attacks in subjects with Type I or II hereditary angioedema (HAE). In each study part, subjects will treat 3 attacks with BCX7353 (2 attacks) or placebo (1 attack), in a randomly allocated order. In Part 1, the dose of 750mg will be assessed relative to placebo in up to 36 patients. If this is shown to be effective, then a further 12 patients will be enrolled at a 500mg dose (Part 1), followed by a further 12 (if efficacy still shown) at a dose of 250mg (Part 3) to determine the minimum effective dose of BCX7353 compared to placebo for treating HAE attacks. Efficacy will be determined by subject diary entries completed at pre-defined times post-dose.

First-in-Human Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics...

Hereditary Angioedema

This is a 3-part Phase 1 dose-ranging study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single (Part 1) and multiple (Part 2) ascending doses of BCX7353 in healthy subjects, and single and multiple doses of BCX7353 in healthy Japanese subjects. Pharmacokinetics is an analysis of how the body handles the study drug BCX7353 and pharmacodynamics is an analysis of the activity the study drug BCX7353 may have in the body.

Pharmacogenetics of Ace Inhibitor-Associated Angioedema

HypertensionDiabetes Type 2

The investigators would like to find out if sitagliptin (dipeptidyl peptidase-4 or DPP4 inhibition), a drug to treat diabetes, affects blood vessel relaxation in healthy people receiving enalapril (angiotensin converting enzyme or ACE inhibition), a blood pressure medicine. Understanding how these drugs interact in healthy people will help us learn their potential effects in people who have diabetes.

A Randomized, Double-Blind, Placebo-Controlled Study of Omalizumab for Idiopathic Anaphylaxis

AnaphylaxisHypotension2 more

Background: Omalizumab is an approved drug for the treatment of asthma by the Food and Drug Administration. Researchers are now studying this drug in a double-blind placebo-controlled manner to assess efficacy in patients with idiopathic anaphylaxis (recurrent hypersensitive allergic episodes for which a cause is not identified). The study will improve understanding of the mechanisms involved in anaphylactic reactions as a response to the downregulation (a decrease in the number of receptors on the surface of cells) in mast cell (a resident cell with several types of tissues) activation, and lead to the development of strategies to better prevent or treat anaphylaxis. Objectives: To determine whether treatment with omalizumab will reduce or prevent episodes of unprovoked anaphylaxis (an acute allergic reaction) in subjects with a history of idiopathic anaphylaxis. To assess pharmacodynamics (physiological effects of a drug) and identify patients with undiagnosed mastocytosis (rare disorders caused by too many mast cells). To investigate cellular and molecular mechanisms of signaling and the effect of omalizumab on mast cells or basophils (a cell in the leukocyte family that releases histamine, which affects allergic response) and explore other regulatory pathways that may be involved with modulation of mast cell degranulation. Eligibility: Patients between 18 and 70 years of age who have been diagnosed with idiopathic anaphylaxis, a diagnosis that is made only after other causes of anaphylaxis have been considered. Patients with documented anaphylaxis episodes (mild to severe) at least six times within the past 1 year period, at least once within the last 4 months, and with at least one of the following: Elevated serum tryptase above baseline within 2 hours of the event. Emergency room visit with documented anaphylaxis without a known cause established by the acute onset of an illness (minutes to several hours) with involvement of the skin, mucosal tissue, or both (generalized hives, itching or flushing, swollen lips-tongue-throat) and at least one of the following: (1) respiratory compromise or gastrointestinal involvement (shortness of breath, wheeze-bronchospasm, throat tightness, low oxygen levels, nausea, vomiting, or abdominal pain); or (2) reduced blood pressure or associated symptoms of end-organ dysfunction (collapse, loss of consciousness, or loss of bladder or bowel control). Hospitalization for anaphylaxis. Patients must provide a letter of referral, with copies of pertinent medical history and laboratory tests, from the prospective participant s local physician, and have the ability to give informed consent. Women with childbearing potential must have a negative pregnancy test, and must agree to practice abstinence or effective birth control from the start of the protocol and for 3 months following the last injection of the study drug. Design: Participants will undergo a clinical evaluation, blood tests, and a bone marrow biopsy and aspirate. Participants will be randomized to either drug or placebo and will receive two doses of omalizumab or a matched placebo while hospitalized, followed by continued outpatient therapy, every 2 to 4 weeks, for up to 6 months. Participants will remain on the assigned regimen for 6 months or until they have experienced new onset of severe adverse event on one occasion within 24 hours of study medication that are related to the study drug, whichever comes first. At that time, the participant will be discontinued from drug administration.

Safety and Efficacy Study of Repeated Doses of DX-88 (Ecallantide) to Treat Attacks of Hereditary...

Hereditary Angioedema (HAE)

The purpose of this study is to evaluate the efficacy and safety of repeated doses of ecallantide in the treatment of acute attacks of hereditary angioedema and to allow HAE patients continued access to ecallantide. In addition, patients enrolled in DX-88/20 (EDEMA4) trial will be followed up and treated for subsequent attacks in this trial.
