In an interview with Pharmacy Times®, Allan L. Klein, MD, FRCP (C), FACC, FAHA, FASE, FESC, director at Pericardial Disease Center and professor of medicine, and Sean Krohn, PharmD, CSP, MSCS, lead clinical pharmacist, specialty pharmacy, discussed a complex case of severe pericarditis in an elderly patient who could not tolerate traditional treatments like NSAIDs or colchicine. The medical team, in collaboration with pharmacists, opted to use rilonacept and worked to expedite its delivery to the patient upon hospital discharge. Krohn highlighted the pharmacy team’s role in prioritizing urgent medication needs, conducting comprehensive drug interaction checks, and monitoring potential side effects like immunosuppression and injection-related reactions. Klein emphasized the importance of careful follow-up, medication tapering, and ongoing monitoring to ensure the patient’s successful treatment and management of pericarditis.

Pharmacy Times: Could you describe a specific instance where collaboration with a pharmacist proved particularly beneficial in managing a patient with pericarditis treated with rilonacept? What specific contributions did the pharmacist make?

Allan L. Klein, MD, FRCP (C), FACC, FAHA, FASE, FESC: I will give you a scenario. Just recently, I saw a gentleman in the outpatient clinic that had pretty severe, recurrent pericarditis. He couldn’t be on NSAIDs because of renal insufficiency, and he wasn’t tolerating the colchicine, and he had severe inflammation and CRPD, and he had many ER visits in the last month. There’s 2 ways to go into a gentleman like this. I can just give him steroids and say, “Start 40 milligrams of prednisone.” But that’s not such a wise thing, and I believe he was 85 years old, so we decided to admit him. That’s where the pharmacist played a major role, and also the industry that makes the rilonacept. What we did was we admitted him to the hospital. We gave instructions to maybe try to restart colchicine in a smaller dose, no NSAIDs, and instead of prednisone, we gave him anakinra. But anakinra, it’s a certain approval process, but we didn’t want him on anakinra long term. We wanted him on rilonacept. My team, the nurse practitioner coordinator, contacted the pharmacy. Basically, we did the paperwork for rilonacept, which would take some time, and maybe Sean can go over that process. But we phoned the company that makes it. We asked for a fast-track approach so when the patient leaves the hospital on anakinra, he would stop the anakinra, and the rilonacept would be delivered to his door. This happened on a mission on a Thursday, and he had been discharged on a Monday or Tuesday, and he had rilonacept at his door. Maybe Sean could elaborate further on that whole process of getting things fast-tracked or just getting things initiated.

Sean Krohn, PharmD, CSP, MSCS: I think in this particular scenario, it’s very important to know how to prioritize the more urgent situations, such as this one, to get patients out of the hospital as quickly yet safely as possible, knowing the extenuating circumstances for this patient. I think we did a special weekend delivery for his patient. A lot of times, the patient’s discharge may be dependent on the patient receiving medication. Our pharmacy team here is trained to know how to prioritize those particular situations.

Pharmacy Times: What role do you see the pharmacist playing in monitoring patients on rilonacept for potential adverse effects or drug interactions? Are there specific laboratory parameters or clinical signs that you would want the pharmacist to be particularly vigilant about?

Krohn: We typically look at immunosuppression and injection-related reactions when we monitor our rilonacept patients. We also look, for example, at the potential for hyperlipidemia. We want to see that baseline lipid panel, in addition to the typical baseline comprehensive metabolic panel, complete blood count, TB tests, and hepatitis B, to rule out any active or latent infections, as well as any undiagnosed hyperlipidemia, for which we would weigh the risk versus the benefit of starting a patient on rilonacept. In terms of drug interactions, our clinical pharmacists perform a comprehensive drug-drug interaction check prior to arranging the initial rilonacept delivery. Any interactions, for example, with another immunosuppressive biologic, can be addressed proactively. We advise patients to monitor on their end and report any increased incidence of infections. Whether it be increased incidence of upper respiratory infections or generalized infections with this medication.

Klein: In terms of our follow-up in the outpatient, we have a pericardial center, and that’s manned by several cardiologists who see these patients. We have a pericardial coordinator that sees these patients as well and follows up. If I were to visit on day 1, 3 months later, the nurse practitioner would follow up with the patient and monitor for any side effects. One thing you should know is that once you start the rilonacept, you’re trying to wean off quickly within the 12 weeks. Often, they’re on ibuprofen, steroids, and colchicine. It’s important to make sure they’re tapering those other medicines appropriately and that their chest pain has disappeared. Rarely do we see some side effects, and then we work with the pharmacist to make sure that the dosing is correct as well. We do monitor very, very carefully. The major side effect would be the upper respiratory tract infection; they have more colds, and sometimes where they inject it may get red. There is a lot of collaboration with the pharmacy on this. Once again, it is benign medicine but can have some side effects as well.

The Vital Role of Pharmacists in Rilonacept Treatment

Rilonacept, a recombinant fusion protein, is a crucial medication for treating conditions like Cryopyrin-Associated Periodic Syndromes (CAPS), including Familial Cold Autoinflammatory Syndrome (FCAS) and Muckle-Wells Syndrome (MWS). Understanding how pharmacists contribute to the safe and effective use of Rilonacept is essential for both patients and healthcare providers.

Understanding Rilonacept and Its Uses

Rilonacept works by blocking interleukin-1 beta (IL-1β), a protein that plays a key role in inflammation. By neutralizing IL-1β, Rilonacept helps to reduce the symptoms associated with CAPS. While highly effective, its use requires careful management and monitoring, where pharmacists play a crucial role.

Conditions Treated with Rilonacept

Familial Cold Autoinflammatory Syndrome (FCAS): A rare genetic disorder causing recurrent episodes of fever,rash,and joint pain triggered by cold exposure.
Muckle-Wells Syndrome (MWS): A more severe CAPS variant characterized by urticaria-like rash, fever, joint pain, hearing loss, and potential amyloidosis.
CAPS (Cryopyrin-Associated Periodic Syndromes): A group of autoinflammatory diseases caused by mutations in the NLRP3 gene.

Pharmacists ensure that patients understand the specific condition Rilonacept is treating and how the medication is intended to help manage their symptoms.

The Pharmacist’s Role in Dispensing Rilonacept

Dispensing Rilonacept is more than just handing over a prescription. It involves a thorough process to ensure patient safety and adherence.

Prescription Verification and Accuracy

Pharmacists meticulously review prescriptions to verify:

Dosage accuracy: Ensuring the prescribed dose aligns with the patient’s condition and weight (in pediatric cases).
Frequency and route of management: Confirmation that the instructions are clear and appropriate for subcutaneous self-injection.
Potential drug interactions: Screening for interactions with other medications the patient is taking.
Allergies and contraindications: Checking the patient’s medical history to avoid adverse reactions.

Proper Storage and handling Education

Rilonacept requires specific storage conditions to maintain its effectiveness. Pharmacists educate patients on:

Refrigeration requirements: Storing Rilonacept vials in the refrigerator (2°C to 8°C or 36°F to 46°F) and protecting it from light.
Expiration dates: Understanding and adhering to the expiration date printed on the vial.
Avoiding freezing: Ensuring the medication is never frozen, as this can damage the protein structure and reduce its efficacy.

Improper storage can render Rilonacept ineffective. This knowledge is vital for patients managing their medication at home.

Compounding and Readiness (if applicable)

While Rilonacept is usually available as a pre-filled syringe or vial, in rare instances, a pharmacist might need to prepare a specific dose. In such cases, pharmacists adhere to strict sterile compounding procedures. This ensures the medication’s safety and prevents contamination.

Patient Counseling and education

Patient education is a cornerstone of pharmaceutical care when it comes to Rilonacept therapy. Pharmacists provide detailed counseling on various aspects of treatment.

Administration Techniques

Rilonacept is administered via subcutaneous injection. Pharmacists provide comprehensive training on:

Selecting an appropriate injection site: recommending sites on the abdomen, thigh, or upper arm, rotating sites to avoid lipodystrophy.
proper injection technique: Demonstrating the correct technique, emphasizing the importance of using a clean needle and maintaining sterility.
Disposal of used syringes: Educating patients on safe disposal methods using a sharps container.

Managing potential Side Effects

While Rilonacept is generally well-tolerated, it can cause side effects.Pharmacists counsel patients on:

Common side effects: Discussing potential side effects like injection site reactions, upper respiratory infections, and headaches.
recognizing severe side effects: Educating patients on signs and symptoms of serious adverse events,such as severe infections or allergic reactions.
Strategies for managing side effects: Providing tips on how to alleviate common side effects, such as using ice packs for injection site reactions.

Pharmacists also emphasize the importance of reporting any unusual or concerning symptoms to their healthcare provider promptly.

Adherence and Reminders

Adherence to rilonacept therapy is critical for achieving optimal outcomes. Pharmacists can help patients stay on track by:

Setting up reminders: Recommending reminder systems, such as using smartphone apps or pillboxes, to ensure consistent dosing.
Addressing concerns and barriers: Identifying and addressing any challenges patients face in adhering to their medication regimen, such as difficulties with self-injection.

Monitoring and Follow-Up

Pharmacists play a vital role in monitoring Rilonacept therapy to assess its effectiveness and detect potential problems early.

Assessing Treatment Response

Pharmacists can work with patients and other healthcare providers to monitor the effectiveness of Rilonacept. This can include:

Tracking symptom enhancement: Monitoring changes in symptoms like fever, rash, and joint pain.
Reviewing lab results: Assessing relevant lab values, such as inflammatory markers (e.g.,CRP,ESR),to gauge treatment response.

Identifying and Managing Drug Interactions

Pharmacists are experts in drug interactions. They carefully screen for potential interactions between Rilonacept and other medications, including:

Immunosuppressants: monitoring for increased risk of infection when Rilonacept is used with other immunosuppressants.
Live vaccines: Advising patients to avoid live vaccines while on Rilonacept therapy due to the increased risk of infection.
Other biologics: Cautioning against concurrent use of other biologics without careful consideration.

Reporting Adverse Events

Pharmacists are mandated reporters of adverse drug events. They promptly report any suspected adverse reactions to Rilonacept to the appropriate regulatory agencies, contributing to drug safety surveillance.

Collaboration with the Healthcare Team

Effective Rilonacept therapy involves a collaborative approach, with pharmacists working closely with physicians, nurses, and other healthcare professionals.

Communication with Physicians

Pharmacists communicate with physicians to:

Clarify prescriptions: Seek clarification on any ambiguities or discrepancies in the prescription.
Report concerns: Alert physicians to any potential drug interactions, allergies, or other concerns.
Provide recommendations: Offer evidence-based recommendations to optimize Rilonacept therapy.

Patient Advocacy

Pharmacists act as advocates for their patients, ensuring they receive the best possible care.This includes:

Navigating insurance coverage: Assisting patients in navigating insurance coverage and accessing financial assistance programs for Rilonacept.
Addressing patient concerns: Providing a safe and confidential space for patients to discuss their concerns and anxieties about rilonacept therapy.

Special Considerations

Certain patient populations require special consideration when using Rilonacept.

Pediatric Patients

In children, dosage adjustments based on weight are crucial. Pharmacists verify the accuracy of these calculations and provide appropriate dosing tools.They also counsel parents or guardians on the safe and effective administration of Rilonacept to their children.

Pregnant and Breastfeeding Women

The safety of Rilonacept during pregnancy and breastfeeding is not fully established.Pharmacists counsel women of childbearing potential on the potential risks and benefits of Rilonacept therapy and discuss appropriate contraception measures.

Benefits and Practical Tips

Understanding the benefits and incorporating practical tips can greatly improve the Rilonacept treatment journey.

Benefits

Reduced Inflammation: Rilonacept effectively lowers inflammation markers, providing relief from CAPS symptoms.
Improved Quality of Life: Effective symptom management leads to increased daily functioning and improved overall well-being.

Practical Tips
