How to get ahead of spring allergy season
DAYTON, Ohio (WDTN) — Allergy season is ramping up in the Buckeye state with tree pollen in full swing, and grass pollen season right around the corner this summer.
With temperatures getting warmer, allergy season gets worse, leaving people battling with symptoms for longer. But taking an everyday allergy medication before the season starts can help you with the battle.
'Those medications work very well to prevent the allergies from flaring up,' said Dr. Joseph Allen, Premier Health regional medical director. 'And once they flare up, they're not as effective. So if you're able to take it early and before things start, it works out really well.'
If daily medications don't alleviate allergy symptoms, a trip to the doctor's office may be in order, where they can prescribe stronger drugs to help with inflammation. 'There are things we can use to treat, we up the ante a little bit and use a little stronger, typically a steroid and many, many folks are familiar with those,' said Allen. 'We use those quite a bit whether it is Prednisone or Medrol or some other steroid that we may use, and that may be a pill or a shot or something else.'
Allen says if these solutions don't work for you, don't be afraid to go back and try something else.
'Don't be miserable for too long,' he said. The Miami Valley is not a stranger to storms over the past month. While those storms will give you short term relief by knocking pollen to the ground, when the ground dries out, that pollen is thrown into the air.'As the wind blows through, it stirs up all that dust and pollen, and all the other things that cause allergies,' said Allen. 'So on those rainy, windy days, the rain knocks it down a little bit, but that wind picks it all back up as soon as it stops raining, and it can be pretty miserable for folks.'If you want to know what you are specifically allergic to, you can contact your doctor, and get a skin prick test done.

Dupixent® (dupilumab) Demonstrated Superiority Over Xolair® (Omalizumab) in Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) in Patients with Coexisting Asthma in First-ever Presented Phase 4 Head-to-Head Respiratory Trial
By GlobeNewswire Published on June 15, 2025, 20:21 IST New late-breaking data at EAACI showed Dupixent outperformed Xolair across all primary and secondary efficacy endpoints of CRSwNP and in all asthma-related endpoints Dupixent also outperformed Xolair in improving such key signs and symptoms as nasal polyp size and sense of smell in CRSwNP, and lung function and disease control in asthma, with rapid improvements seen as early as 4 weeks Results reinforce the efficacy of Dupixent in treating both upper and lower respiratory diseases by targeting IL-4 and IL-13, two key drivers of type 2 inflammation TARRYTOWN, N.Y. and PARIS, June 15, 2025 (GLOBE NEWSWIRE) — Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi today presented positive results from the EVEREST Phase 4 trial in adults with severe chronic rhinosinusitis with nasal polyps (CRSwNP) and coexisting asthma. In the trial, Dupixent® (dupilumab) outperformed Xolair® (omalizumab) on all primary and secondary efficacy endpoints of CRSwNP, and in all asthma-related endpoints. The data are from the first-ever presented head-to-head respiratory trial with biologic medicines and were shared in a late-breaking oral presentation at the 2025 European Academy of Allergy and Clinical Immunology (EAACI) Annual Congress. 'Patients suffering from chronic rhinosinusitis with nasal polyps often live with the constant obstruction of their nasal passages that can lead to burdensome nasal congestion and loss of smell. What's more, a majority of these individuals also have asthma that can substantially impact their quality of life,' said Eugenio De Corso, M.D., Ph.D., ENT Specialist, Otolaryngology, Head and Neck Surgery, Rhinology, A. Gemelli University Hospital Foundation, IRCSS, Rome, Italy, and lead investigator of the study. 'EVEREST is the first-ever trial to demonstrate the superiority of Dupixent over Xolair on CRSwNP endpoints in patients with coexisting asthma, along with generally similar safety profiles. Together, these Dupixent outcomes provide important insights that will help guide patients and physicians through the treatment decision-making process.' In the EVEREST trial, 360 adults with severe, uncontrolled CRSwNP and coexisting asthma were randomized to receive Dupixent 300 mg (n=181) every two weeks or a weight- and immunoglobulin E (IgE) level-based dosing regimen of Xolair (n=179) every two or four weeks. Both Dupixent and Xolair were added to background mometasone furoate nasal spray (MFNS). Primary and secondary endpoint results in CRSwNP for patients treated with Dupixent compared to Xolair at 24 weeks were as follows, with differences seen as early as 4 weeks: 1.60-point superior reduction in nasal polyp size , a primary endpoint (p<0.0001 a ) , a primary endpoint (p<0.0001 ) 8.0-point superior improvement in ability to identify different smells , a primary endpoint (p<0.0001 a ). More patients on Dupixent improved above the anosmia threshold compared to Xolair. , a primary endpoint (p<0.0001 ). More patients on Dupixent improved above the anosmia threshold compared to Xolair. 0.58-point superior reduction in nasal congestion/obstruction , a key secondary endpoint (p<0.0001 a ) , a key secondary endpoint (p<0.0001 ) 0.81-point superior improvement in loss of smell , a key secondary endpoint (p<0.0001 a ) , a key secondary endpoint (p<0.0001 ) 1.74-point superior reduction in symptom severity (p<0.0001 a ) (p<0.0001 ) 12.7-point difference in health-related quality of life (p<0.0001 b ) (p<0.0001 ) 31.27-point difference in peak nasal inspiratory flow (p<0.0001 b ) (p<0.0001 ) 1.87-point difference in overall severity of rhinosinusitis (p<0.0001b) Asthma endpoint results for patients treated with Dupixent compared to Xolair at 24 weeks were as follows, with differences seen as early as 4 weeks: 150 mL difference in lung function (pre-bronchodilator FEV 1 ; p=0.003 b ) (pre-bronchodilator FEV ; p=0.003 ) 0.48-point difference in asthma control (p<0.0001b) a Statistically significant b Nominally significant as the endpoint was not included in the multiplicity adjustment hierarchy The safety results in the EVEREST trial were generally consistent with the known safety profile of Dupixent in its approved respiratory indications, with similar overall rates of adverse events (AEs) observed between Dupixent (64%) and Xolair (67%). Serious AEs were reported in 2% and 4% of patients treated with Dupixent and Xolair, respectively. Additionally, AEs leading to trial discontinuation were reported in 3% of Dupixent patients and 1% of Xolair patients. About the Dupixent Phase 4 Trial EVEREST is a randomized, double-blind Phase 4 trial comparing the efficacy and safety of Dupixent to Xolair in adults with severe, uncontrolled CRSwNP and coexisting mild, moderate or severe asthma. During the 24-week trial, patients received Dupixent 300 mg every two weeks or Xolair 75 to 600 mg every two or four weeks, which was added to background MFNS. Xolair dosing was determined based on body weight and serum total IgE levels as per the approved label. All endpoints were assessed at 24 weeks. The primary endpoints assessed change from baseline in nasal polyp score (NPS; scale: 0-8) and the University of Pennsylvania Smell Identification Test (UPSIT; scale: 0-40). Secondary endpoints included change from baseline in nasal congestion (NC; scale: 0-3), loss of smell (LoS; scale: 0-3), total symptom score (TSS; scale: 0-9), Sino-Nasal Outcome Test-22 (SNOT-22; scale: 0-110), peak nasal inspiratory flow, and rhinosinusitis disease severity (visual analogue scale: 0-10 cm). Other endpoints assessed pre-bronchodilator forced expiratory volume over one second (pre-BD FEV 1 ) and the 7-item Asthma Control Questionnaire (ACQ-7; scale: 0-6). About Dupixent Dupixent, which was invented using Regeneron's proprietary VelocImmune ® technology, is a fully human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) pathways and is not an immunosuppressant. The Dupixent development program has shown significant clinical benefit and a decrease in type 2 inflammation in Phase 3 trials, establishing that IL-4 and IL-13 are two of the key and central drivers of the type 2 inflammation that plays a major role in multiple related and often co-morbid diseases. Dupixent has received regulatory approvals in more than 60 countries in one or more indications including certain patients with atopic dermatitis, asthma, CRSwNP, eosinophilic esophagitis (EoE), prurigo nodularis, chronic spontaneous urticaria (CSU) and chronic obstructive pulmonary disease (COPD) in different age populations. More than 1,000,000 patients are being treated with Dupixent globally.1 About Regeneron's VelocImmune Technology Regeneron's VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron's co-Founder, President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite ® technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create a substantial proportion of all original, FDA-approved fully human monoclonal antibodies. This includes Dupixent® (dupilumab), Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb), Inmazeb® (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz® (pozelimab-bbfg). In addition, REGEN-COV® (casirivimab and imdevimab) had been authorized by the FDA during the COVID-19 pandemic until 2024. Dupilumab Development Program Dupilumab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement. To date, dupilumab has been studied across more than 60 clinical trials involving more than 10,000 patients with various chronic diseases driven in part by type 2 inflammation. In addition to the currently approved indications, Regeneron and Sanofi are studying dupilumab in a broad range of diseases driven by type 2 inflammation or other allergic processes in Phase 3 trials, including chronic pruritus of unknown origin, bullous pemphigoid and lichen simplex chronicus. These potential uses of dupilumab are currently under clinical investigation, and the safety and efficacy in these conditions have not been fully evaluated by any regulatory authority.

Intellia Therapeutics Announces Positive Three-Year Data from Phase 1 Trial of Lonvoguran Ziclumeran (lonvo-z) in Patients with Hereditary Angioedema (HAE) at the European Academy of Allergy and Clinical Immunology Congress
With up to three years of follow-up, a single dose of lonvo-z led to a 98% mean reduction in monthly HAE attack rate in all 10 patients All 10 patients were attack-free and treatment-free for a median of 23 months through the latest follow-up, demonstrating the potential of lonvo-z to become the first one-time therapy for most HAE patients Lonvo-z was well tolerated and continues to demonstrate a favorable safety profile The global Phase 3 HAELO trial of lonvo-z has concluded screening ahead of schedule with more than half screened from U.S. sites; Intellia to provide an update on enrollment in the future CAMBRIDGE, Mass., June 15, 2025 (GLOBE NEWSWIRE) — Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading clinical-stage gene editing company focused on revolutionizing medicine with CRISPR-based therapies, today announced three-year follow-up data from the Phase 1 portion of the ongoing Phase 1/2 study in patients with HAE after receiving a single dose of lonvoguran ziclumeran (lonvo-z, also known as NTLA-2002). Results were shared in an oral presentation at the European Academy of Allergy and Clinical Immunology (EAACI) Congress 2025, held June 13-16 in Glasgow, United Kingdom. 'Today's results underscore the promising potential of Intellia's approach to gene editing therapy – a one-time treatment that was well tolerated and offered a highly differentiated, durable effect for patients suffering from a serious disease,' said Intellia President and Chief Executive Officer John Leonard, M.D. 'Seeing all 10 patients in the Phase 1 portion of this study free from both HAE attacks and chronic therapy at nearly two years of median follow-up is incredibly encouraging. These data fuel our optimism for the outcomes of our ongoing Phase 3 HAELO study, which we expect to report in the first half of 2026, and highlight the strong value we believe it will offer patients, physicians and payers.' 'People living with HAE often report a reduced quality of life because they worry about the likelihood of their next attack, either because they still experience attacks or are reminded of it by their use of chronic therapy,' said Dr. Joshua Jacobs, Medical Director, Allergy and Asthma Clinical Research, Inc. 'Based on the data, it is reasonable to expect lonvo-z could offer patients the potential to be free from both physical HAE attacks and the burden of managing chronic HAE treatment.' In the Phase 1 portion of the study, a one-time dose of 25 mg (N=3), 50 mg (N=4) or 75 mg (N=3) of lonvo-z was administered via intravenous infusion and plasma kallikrein protein levels were measured along with HAE attacks. At the time of the February 12 data cutoff, patients were attack-free and treatment-free for a median of nearly two years. With up to three years of follow-up, a single dose of lonvo-z led to a mean reduction in monthly HAE attack rate of 98% over the study period, compared to pre-treatment baseline. For all 10 patients, deep, dose-dependent and durable reductions in plasma kallikrein protein continued to be observed through the latest assessment. Safety Across all three dose levels, lonvo-z has been well tolerated and continues to demonstrate a favorable safety profile consistent with earlier data presented at EAACI in 2024. The most frequent adverse events during the study period were infusion-related reactions (IRRs). IRRs were mostly Grade 1 and resolved with all patients receiving the full dose. With up to 3 years of follow-up, no treatment-emergent serious adverse events were observed, and no treatment-related adverse events were observed during the period following 28 days after dosing. Clinical Development Plans Intellia's global Phase 3, randomized, double-blind, placebo-controlled HAELO trial is ongoing to assess the safety and efficacy of lonvo-z at the 50 mg dosage. The Company announced today the HAELO trial has successfully completed screening ahead of schedule, with over half of the patients being screened in the United States. The study is no longer recruiting and Intellia will provide an update on enrollment in the future. New and longer-term data from the Phase 2 portion of the ongoing Phase 1/2 study is planned to be presented in the second half of 2025. Intellia expects to submit a biologics license application (BLA) in 2026 to support the Company's plans for a U.S. launch in 2027.

Celldex Presents Data Demonstrating Profound Long Term Improvement in Angioedema in Barzolvolimab Phase 2 Study in Chronic Spontaneous Urticaria at EAACI 2025
77% of patients (150 mg Q4W) treated with barzolvolimab who had angioedema at baseline were angioedema free at Week 52 (150 mg Q4W) Data further support barzolvolimab clinical benefit to patients with CSU HAMPTON, N.J., June 14, 2025 (GLOBE NEWSWIRE) — Celldex Therapeutics, Inc. (NASDAQ:CLDX) today announced data demonstrating that barzolvolimab profoundly improves angioedema at 52 weeks in the Company's Phase 2 clinical trial in chronic spontaneous urticaria (CSU). Angioedema, characterized by swelling of the deeper dermal layers of the skin and mucous membranes, is a painful, debilitating symptom of CSU that has significant impact on quality of life. It commonly affects the face (lips and eyelids), hands, feet, and genitalia but can also involve the tongue, uvula, soft palate, and pharynx1. The data were presented today by Dr. Martin Metz, Professor, Department of Dermatology and Allergy, Head of Translational Research and Deputy Head of Clinical Trials at Charité – Universitätsmedizin in Berlin, in an oral presentation at the European Academy of Allergy and Clinical Immunology (EAACI) Congress 2025. Celldex previously announced that the Phase 2 study in CSU met its primary and secondary endpoints at 12 weeks with clinically meaningful and statistically significant decreases in UAS7 (weekly urticaria activity score) compared to placebo across multiple dose groups, including improvements in quality of life and angioedema measurements, and demonstrated a favorable safety profile. The data presented today further support these results by demonstrating improvements in AAS7 (weekly angioedema activity score) and additional measures of angioedema control over the 52 week treatment period. AAS7 measures the frequency and intensity of angioedema episodes, where higher scores indicate increased angioedema activity. 'The majority of patients with severe CSU suffer with angioedema, which is often extremely painful and causes disfigurement, dramatically impacting quality of life,' said Diane C. Young, MD, Senior Vice President and Chief Medical Officer of Celldex Therapeutics. 'Consistent with previously reported clinical outcomes, we observed rapid, profound angioedema relief with barzolvolimab treatment and this benefit continued to improve over 52 weeks of therapy for patients. These data add to the unprecedented 76 week efficacy and safety data we presented yesterday at EAACI and continue to support barzolvolimab's potential to redefine the treatment landscape and meet the goals of CSU therapy—rapid, profound, durable complete response and improved quality of life across a broad patient population.' Summary of Key Findings: Patients on study had severe CSU. Over 70% of patients had a weekly urticaria activity score (UAS7) greater than 28 at baseline and reported very high rates of angioedema at baseline. Barzolvolimab demonstrated rapid, robust and durable improvements in angioedema symptoms over the treatment period. At Week 52, an 86% mean reduction from baseline was reported for 150 mg Q4W arm and an 82% reduction was reported for the 300 mg Q8W. Up to 77% of patients treated with barzolvolimab who had angioedema at baseline were angioedema free (AAS7=0) at Week 52. Patients treated with barzolvolimab were angioedema free up to 72% of the time over the 52 week treatment period. Up to 87% of patients reported clinically meaningful improvement ( > 8 point) in AAS7 at Week 52. 1 DermNet . About Barzolvolimab Barzolvolimab is a humanized monoclonal antibody that binds the receptor tyrosine kinase KIT with high specificity and potently inhibits its activity. KIT is expressed in a variety of cells, including mast cells, which mediate inflammatory responses such as hypersensitivity and allergic reactions. KIT signaling controls the differentiation, tissue recruitment, survival and activity of mast cells. In certain inflammatory diseases, such as chronic urticaria, mast cell activation plays a central role in the onset and progression of the disease. Barzolvolimab is currently being studied in chronic spontaneous urticaria (CSU), chronic inducible urticaria (CIndU), prurigo nodularis (PN), eosinophilic esophagitis (EOE) and atopic dermatitis (AD), with additional indications planned for the future. About the Phase 2 CSU Study The randomized, double-blind, placebo-controlled, parallel group Phase 2 study evaluated the efficacy and safety profile of multiple dose regimens of barzolvolimab in patients with CSU who remain symptomatic despite antihistamine therapy, to determine the optimal dosing strategy. 208 patients were randomly assigned on a 1:1:1:1 ratio to receive subcutaneous injections of barzolvolimab at 75 mg every 4 weeks, 150 mg every 4 weeks, 300 mg every 8 weeks or placebo during a 16-week placebo-controlled treatment period. After 16 weeks, patients then entered a 36-week active treatment period, in which patients receiving placebo or the 75 mg dose were randomized to receive barzolvolimab 150 mg every 4 weeks or 300 mg every 8 weeks; patients already randomized to the 150 mg and 300 mg treatment arms remained on the same regimen as during the placebo-controlled treatment period. After 52 weeks, patients entered a follow-up period for an additional 24 weeks. Barzolvolimab achieved the primary efficacy endpoint of the study—a statistically significant mean change from baseline to Week 12 in UAS7 (weekly urticaria activity score) compared to placebo at all dose levels. For additional information on this trial (NCT05368285), please visit About the Phase 3 Program Celldex is currently conducting a global Phase 3 Program for barzolvolimab in CSU, consisting of two Phase 3 trials (EMBARQ-CSU1; NCT06445023 and EMBARQ-CSU2; NCT06455202) designed to establish the efficacy and safety of barzolvolimab in adult patients with CSU who remain symptomatic despite H1 antihistamine treatment. The studies also include patients who remain symptomatic after treatment with biologics. Enrollment is underway. About Chronic Spontaneous Urticaria (CSU) CSU is characterized by the occurrence of hives or wheals for 6 weeks or longer without identifiable specific triggers or causes. The activation of the mast cells in the skin (release of histamines, leukotrienes, chemokines) results in episodes of itchy hives, swelling and inflammation of the skin that can go on for years or even decades. Current therapies provide symptomatic relief only in some patients. About Celldex Celldex is pioneering new horizons in immunology to deliver life-changing therapies. We are relentless in our pursuit of novel antibody-based treatments that engage the human immune system and directly affect critical pathways to improve the lives of patients with allergic, inflammatory and autoimmune disorders.
