Research Roundup, September 2025

In this month’s roundup, we highlight recent studies and announcements related to eosinophil-associated diseases:

HES Burden

A new JACI Global study highlights the significant daily burden faced by patients with hypereosinophilic syndromes (HES), including impacts on health and quality of life. APFED is proud to have participated in this project, and we thank the patients and families who shared their experiences.

EGPA: NS-229 Fast Track

The FDA has granted Fast Track designation to NS-229, an investigational JAK1 inhibitor for eosinophilic granulomatosis with polyangiitis (EGPA). This designation is intended to speed development of treatments for serious medical conditions that fulfill an unmet need.

Mepolizumab and Mood

A study of patients enrolled in the Australian Mepolizumab Registry finds that patients with severe eosinophilic asthma taking mepolizumab, alongside reduced oral steroid use, also experienced improvements in depression and anxiety symptoms. The study concludes that “this further highlights the role of biologics in oral steroid stewardship initiatives.”

Environmental Risk and EoE

A new study in Frontiers in Allergy looked at whether exposure to particulate matter (PM2.5 and PM10) is linked to eosinophilic esophagitis (EoE). While environmental exposures remain an area of interest in EoE research, these findings suggest that particulate matter may not be a major risk factor.

Barzolvolimab Phase 2 in EoE

Celldex reported Phase 2 results of barzolvolimab, a mast-cell depleting antibody, in eosinophilic esophagitis (EoE). While the drug met biomarker goals, it did not improve clinical outcomes, suggesting mast cells may not be a key driver in EoE.

College Life with an Eosinophil Associated Disease

September marks a season of new beginnings as students adjust to college life; for those living with eosinophil-associated diseases, this transition can be daunting. However, as LSU student Abigail Watson shares, it’s also full of possibility with the right support and accommodations. Check out her story of thriving with eosinophilic esophagitis on campus from APFED’s newsletter archives:

My name is Abigail Watson, and I attend Louisiana State University (LSU). As a student living with eosinophilic esophagitis (EoE), college can be scary. However, it has the potential to be so awesome!

Some preparations are needed for success. I have worked with LSU’s allergy chefs to ensure that an on-campus dining plan works for me. (How awesome is it that they have allergy chefs?!)  This helps ensure that I will not get sick while eating on campus.

LSU has fantastic accommodations for people living with eosinophilic conditions. I have accommodations like frequent breaks during class and consideration for absences that help when I do get a flareup (usually from eating off campus with friends or stress). I also have a private dorm room, which allows me to feel confident and comfortable while taking my weekly Dupixent® shots. Due to these preparations, I have thrived during freshmen year!

Having an eosinophilic condition in Louisiana is very hard. Not many people, including doctors, are familiar with them. I have had to switch to various doctors in the past. It took almost two years to get to the doctors that I have now. I truly believe more people need to be educated on rare diseases like eosinophilic diseases. Some of my past doctors accused me of “doing this to myself” and “using my parents,” which was untrue. There were a few doctors that had the best intentions of helping me, but they just could not figure out what was wrong with me.

However, there was one doctor who has always been by my side: Dr. Gabe. He is a local urgent care doctor with a big heart. He was unable to help me himself with my condition, but he did not stop until I had my disease manageable. Today, along with my doctors in Boston, Massachusetts, I have my disease managed and I am flourishing in college. I am even on LSU’s rowing team!

My biggest piece of advice for any college student living with eosinophilic esophagitis is to work closely with your school. I know many colleges other than LSU that are accommodating. I have explained my situation thoroughly to LSU’s staff, and I am living my best life because of it. I am able to study confidently, and I have been able to make many true friends. It may be scary to make friends when living with a health condition, but there are many people in college that are understanding. I have come across people who have treated me differently because of my disease, but trust me, there are many good people out there wanting to make friends regardless of the obstacles you face.

Adam’s Legacy: A Commitment to Eosinophilic Disease Research

We are deeply grateful to Mike and Robin Rantz for sharing Adam’s story, and for honoring his memory by raising funds to advance research and awareness for eosinophilic diseases.

At the age of 32, our son, Adam, died unexpectedly from a massive heart attack.

Just eight years prior, he was diagnosed with a disease we had never heard of – eosinophilic fasciitis (EF). It took months to find the right doctor and to get the tests to get a definitive diagnosis. During this time, Adam was in extreme pain. His upper and lower extremities were so inflamed that it was difficult for him to use them. The delay in his care was beyond frustrating.

For the last nine years, we have been searching for answers as to why, at such a young age, our son’s heart failed.

Was it related to the EF? Was it related to the medications used to treat EF?  Was it a heart condition no one had picked up on? So many questions!  It took a long time, but we realized that no one had the answer.

In looking for an answer we found a way to honor Adam’s memory and help bring awareness to this rare disease. Fundraising for APFED has helped us connect with folks like us. Folks looking for answers. Folks looking for better treatment options.

Adam’s older brother, Ethan, took to the internet shortly after Adam’s death, in search of answers and found APFED.  With help from Julie at APFED, they organized the first AMR memorial golf outing. No one had ever heard of EF but by the end of the day of the event, our friends and family were able to pronounce eosinophilic fasciitis.   It was a start.  Ethan and Julie organized three memorial golf outings until COVID shut everything down. Over those 3 years we raised awareness and $50,000 to support eosinophilic disease research.  We are so proud of his efforts.

This year, my husband has spearheaded a fundraising event for APFED once again. Thanks to his efforts, APFED has been named the beneficiary of our community classic car show, Cars for a Cause. It’s a yearly car show that benefits a different charity every year. This year it’s being held on Sunday, September 14, in Quakertown, PA. You can learn more about this event.

Fundraising has given us a way to stay connected with Adam. To honor his memory. It’s not very easy reliving all the pain and hard times Adam went through but it’s a way of grieving as we continue to heal.

To support this event in Adam’s memory, please consider donating here.

Our hope is to bring more awareness to eosinophilic disease and raise funds so the research can continue and one day provide better treatments and maybe even ways to prevent this auto immune disease.

Protecting Your Respiratory Health During Wildfire Season

As wildfire season intensifies across many regions, those living with asthma—including eosinophilic asthma—face heightened health risks that extend far beyond the immediate fire zones. Wildfire smoke can travel hundreds of miles, creating hazardous air quality conditions that may persist for days or weeks.

For people with eosinophilic asthma and other respiratory conditions, smoke exposure presents specific challenges. The fine particulate matter in wildfire smoke can penetrate deep into the lungs, potentially triggering inflammation, worsening existing symptoms, and increasing the risk of severe asthma attacks.

The impact goes beyond physical symptoms. Wildfire seasons can disrupt daily routines, limit outdoor activities, and create anxiety about when the next air quality alert might come. Understanding how to prepare for and respond to these conditions is essential for maintaining respiratory health and quality of life.

APFED has compiled the following resources to help you navigate wildfire season more safely. While this list isn’t exhaustive, these tools and guidelines can help you monitor conditions, protect your health, and know when to seek medical care.
