Pharmacokinetics Of Emulsified Avacopan Applied By NG Tube

Pharmacokinetics Of Emulsified Avacopan In ANCA-associated Vasculitis With Severe Diffuse Alveolar Hemorrhage

Pharmacokinetics Of Emulsified Avacopan Applied By NG Tube (NCT07556484) is a Phase 1 interventional studying Diffuse Alveolar Hemorrhage and Antineutrophil Cytoplasmic Antibody Positive Vasculitis, sponsored by Mayo Clinic. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

The purpose of this study is to determine the 72-hour pharmacokinetics of emulsified avacopan at a dose of 30 mg twice daily given to up to 6 patients with active severe GPA or MPA with diffuse alveolar hemorrhage (DAH) requiring mechanical ventilation for respiratory support.

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Diffuse Alveolar Hemorrhage, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 6 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Inclusion Criteria - Fulfillment of the definitions of the Second Chapel Hill Consensus Conference for ANCA-associated vasculitis (either granulomatosis with polyangiitis (GPA) or microscopic polyangiitis MPA). - Positivity for ANCA, directed against PR3 or MPO. - Diffuse alveolar hemorrhage. - Respiratory failure requiring mechanical ventilation. - Severe newly diagnosed disease or severe relapsing disease. Severe new or relapsing disease is defined as at least one major BVAS/WG item or a score ≥ 3 and the investigator deems standard treatment for severe disease is necessary. - Minimum BVAS-WG of 3. - Requirement of standard-of-care remission induction therapy for active severe ANCA-associated vasculitis (GPA or MPA). Exclusion Criteria - Diagnosis with eosinophilic granulomatosis with polyangiitis (EGPA, formally Churg-Strauss syndrome) as defined by the Chapel Hill consensus conference. - Allergies: History of severe allergic reaction to avacopan - History of documented anti-glomerular basement membrane disease (anti-GBM disease) - Previous administration of avacopan within the last 5 days. - Concomitant use of a strong CYP3A4 inhibitor. - Aspartate aminotransferase \[AST\], alanine amino transferase \[ALT\], alkaline phosphatase, or total bilirubin elevation \>2.5 times the upper limit of normal (unless attributed to vasculitis) on routine liver function testing obtained within 3 days prior to anticipated treatment with avacopan. - Evidence of prior active or current Hepatitis B virus (HBV), hepatitis C virus (HCV), or human weakened immune system (HIV) infection. - Active serious infection, including localized infection. - Pregnancy and breastfeeding Always talk to your doctor about whether this trial is right for you.

How to Talk to Your Doctor About This Trial

Bring the printable summary of this trial — including the NCT ID (NCT07556484), the sponsor (Mayo Clinic), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?

Frequently Asked Questions

What is the NCT07556484 clinical trial studying?

The purpose of this study is to determine the 72-hour pharmacokinetics of emulsified avacopan at a dose of 30 mg twice daily given to up to 6 patients with active severe GPA or MPA with diffuse alveolar hemorrhage (DAH) requiring mechanical ventilation for respiratory support. The full protocol is registered on ClinicalTrials.gov and includes the primary outcome measures, eligibility criteria, and study endpoints.

Who can participate in NCT07556484?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT07556484?

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
