Assessing Contributors to Anxiety: The Unpredictability of HAE

Join us for an engaging discussion on potential contributors to patient anxiety related to hereditary angioedema (HAE). Our expert moderator, John Anderson, MD, clinical assistant professor at The University of Alabama at Birmingham and partner at AllerVie Health/AllerVie Clinical Research, welcomes Kimberly Poarch, PA-C, from Allergy & Asthma Specialists of Dallas. She will share emerging reports on factors impacting anxiety among patients with HAE and explore strategies to engage with patients in managing their disease. Additionally, clinical information about RUCONEST® (C1 esterase inhibitor [recombinant]), an approved on-demand HAE treatment option, will be highlighted.
WHAT IS RUCONEST?
RUCONEST® (C1 esterase inhibitor[recombinant]) is indicated for the treatment of acute attacks in adult and adolescent patients with hereditary angioedema (HAE). Effectiveness in clinical studies was not established in HAE patients with laryngeal attacks.
IMPORTANT SAFETY INFORMATION
RUCONEST is contraindicated in patients with a history of allergy to rabbits or rabbit-derived products and for patients with a history of life-threatening immediate hypersensitivity reactions, including anaphylaxis, to C1 esterase inhibitor (C1-INH) preparations.
Monitor patients for early signs of allergic or hypersensitivity reactions (including hives, generalized urticaria, tightness of the chest, wheezing, hypotension, and/or anaphylaxis). If symptoms occur, discontinue RUCONEST and administer appropriate treatment.
Serious arterial and venous thromboembolic (TE) events have been reported with plasma-derived C1-INH products. Risk factors may include the presence of an indwelling venous catheter/access device, prior history of thrombosis, underlying atherosclerosis, use of oral contraceptives or certain androgens, morbid obesity, and immobility. Monitor patients with known risk factors for TE events during and after RUCONEST administration.
Appropriately trained patients may self-administer RUCONEST upon recognition of an HAE attack. Advise patients to seek medical attention if progress of any attack makes them unable to properly prepare or administer a dose of RUCONEST. No more than 2 doses should be administered within a 24-hour period.
The serious adverse reaction reported in clinical trials was anaphylaxis. The most common adverse reactions (incidence ≥2%) were headache, nausea, and diarrhea.
Before prescribing RUCONEST, please read the full Prescribing Information including the Patient Product Information.

Bridging the Conversation: Redosing in HAE

In our final episode, hereditary angioedema (HAE) treatment redosing takes center stage during a discussion with Dr. John Anderson, clinical assistant professor at The University of Alabama at Birmingham and partner at AllerVie Health, and Dr. Raffi Tachdjian, associate clinical professor at the David Geffen School of Medicine at the University of California, Los Angeles (UCLA). Drs. Anderson and Tachdjian will define redosing and explore misconceptions about redosing with acute HAE treatments. They will also discuss approaches to engage patients to help identify occurrences of redosing and management considerations for patients who consistently redose during HAE attacks. Finally, Drs. Anderson and Tachdjian will share clinical data related to redosing rates for RUCONEST® (C1 esterase inhibitor [recombinant]).

Instilling IV Confidence: Self-Administration in HAE

We’re back with John Anderson, MD, clinical assistant professor at The University of Alabama at Birmingham and partner at AllerVie Health, and Shahnaz Fatteh, MD, physician at the Asthma, Allergy Care Center of Florida, as they address clinician questions around intravenous (IV) self-administration within the context of RUCONEST® (C1 esterase inhibitor [recombinant]). RUCONEST can be administered via IV self-administration and is indicated to treat acute attacks in adult and adolescent patients with hereditary angioedema (HAE). We are delighted to welcome Kelly, a patient with HAE, who will share their experience learning to confidently self-administer an IV. Practical approaches for discussing IV self-administration with patients will be explored. In addition, an overview of RUCONEST training resources for IV self-administration will be highlighted.

Painting the Picture: HAE Types and Management Approaches

Today on “Swell Conversations: A Promotional HAE Series,” John Anderson, MD, clinical assistant professor at The University of Alabama at Birmingham and partner at AllerVie Health, welcomes Douglas H. Jones, MD, practicing physician at the Tanner Clinic in Layton, Utah. In this episode, they break down the three types of hereditary angioedema (HAE) and share their personal approaches to disease management. Special attention is given to exploring HAE when C1 inhibitor (C1-INH) levels and function are deemed normal (ie, HAE-nl-C1INH). Drs Anderson and Jones also discuss the possible role that RUCONEST® (C1 esterase inhibitor [recombinant]) may play in HAE treatment regimens.

Simplifying the Science: The Root Cause of HAE

Join esteemed experts John Anderson, MD, clinical assistant professor at The University of Alabama at Birmingham and Partner at AllerVie Health, and Dareen D. Siri, MD, chief executive officer and physician at Midwest Allergy Sinus Asthma, SC in Illinois, as they explore how and why hereditary angioedema (HAE) occurs, including the multifaceted role of C1 inhibitor. They will also provide their clinical perspectives on connecting with patients and engaging ways to communicate the HAE disease mechanism. At the end of the discussion, Drs Anderson and Siri will discuss the mechanism of action for RUCONEST® (C1 esterase inhibitor [recombinant]).
