Air quality alert issued for Monday for western and central Minnesota

NEXT Weather: 5:30 p.m. forecast from May 11, 2025
An air quality alert was issued due to ozone for western and central Minnesota, by the Minnesota Pollution Control Agency (MPCA).
The agency says air quality is expected to reach the orange Air Quality Index (AQI) category, which is unhealthy for sensitive groups.
The alert takes effect at noon Monday and runs until 9 p.m.
According to the MPCA, the affected area includes the Twin Cities metro, Brainerd, Alexandria, Albert Lea, Marshall, Worthington, St. Cloud, Ortonville, Mankato, Bemidji, East Grand Forks, Moorhead, Roseau, and the tribal nations of Upper Sioux, Mille Lacs, Prairie Island, Leech Lake, and Red Lake.
The MPCA says ground-level ozone is expected to be highest during the afternoon and early evening hours.
It says the mostly sunny skies, warm temperatures and low humidity will create an environment favorable to volatile organic compounds and nitrogen oxides. They are two types of pollutants and produce ground-level ozone when they react in the air.
Ozone is expected to be low in the morning, late evening and overnight.
Unhealthy ozone levels can aggravate lung diseases like asthma, emphysema, and Chronic Obstructive Pulmonary Disease (COPD). The MPCA says people who are more likely to be affected are:
People who have asthma or other breathing conditions
Children and teenagers
People doing extended or heavy physical activity like play sports
Everyone is being urged to take precautions. The MPCA recommends people to:
Limit, change, or postpone your physical activity.
If possible, stay away from local sources of air pollution like busy roads and wood fires.
If you have asthma, or other breathing conditions like COPD, make sure you have your relief/rescue inhaler with you.

Genentech Provides Update on Astegolimab in Chronic Obstructive Pulmonary Disease
– The pivotal Phase IIb ALIENTO study met the primary endpoint of a statistically significant reduction in the annualized exacerbation rate (AER) at 52 weeks when astegolimab was given every two weeks – – The Phase III ARNASA study did not meet the primary endpoint of a statistically significant reduction in the AER at 52 weeks – – The safety profile of astegolimab was consistent with previously reported data, with no new safety signals identified – – Analysis of the ALIENTO and ARNASA data will be discussed with regulatory authorities and shared at an upcoming medical meeting – SOUTH SAN FRANCISCO, Calif., July 21, 2025--(BUSINESS WIRE)--Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today topline results from the pivotal Phase IIb ALIENTO (n=1,301) and the Phase III ARNASA (n=1,375) trials investigating astegolimab compared to placebo, on top of standard of care maintenance therapy in people with moderate to very severe chronic obstructive pulmonary disease (COPD). The studies included a broad population: both former and current smokers, regardless of blood eosinophil count, who have a history of frequent exacerbations. The pivotal Phase IIb ALIENTO study met its primary endpoint and showed that astegolimab reduced the annualized exacerbation rate (AER) by a statistically significant 15.4% at 52 weeks, when given every two weeks. However, the Phase III ARNASA study did not meet its primary endpoint of a statistically significant reduction in the AER, demonstrating a numerical 14.5% reduction at 52 weeks when astegolimab was given every two weeks. The results were generally consistent across secondary endpoints in both studies. The total number of exacerbations was lower than prospectively anticipated in both trials. The safety profile of astegolimab was consistent with previously reported data, with no new safety signals identified. "While COPD remains the third leading cause of death worldwide, patients and families have limited treatment options for managing this debilitating and complex disease," said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. "This was the first set of studies in an 'all-comers' COPD population, and we will discuss these data with regulatory authorities to evaluate next steps for astegolimab." Detailed results from ALIENTO and ARNASA will be shared at an upcoming medical meeting. About the ALIENTO and ARNASA studies Astegolimab is an investigational, fully human anti-ST2 monoclonal antibody designed to bind with high affinity to the ST2 receptor, thereby blocking the signaling of IL-33. The astegolimab COPD pivotal program consists of two registrational studies, the Phase IIb ALIENTO (NCT05037929) and Phase III ARNASA (NCT05595642) studies. Both ALIENTO and ARNASA are double-blinded, placebo-controlled, multi-center studies that evaluate the efficacy and safety of astegolimab administered every two or every four weeks in patients with COPD on top of standard of care maintenance therapy. Patients in the studies included former and current smokers, regardless of blood eosinophil count, who have a history of frequent exacerbations. The primary analysis is based on the initial phase of the study, which consisted of 1,301 patients for ALIENTO and 1,375 patients for ARNASA. The primary endpoint is the reduction in the annualized rate of moderate and severe COPD exacerbations (AER) over the 52-week treatment period. AER is the total number of exacerbations (a sudden worsening in airway function and respiratory symptoms) occurring over the relevant treatment period, divided by the total number of patient years. Standard of care maintenance therapy for both studies was one of the following combinations - inhaled corticosteroid (ICS) plus long-acting beta-agonist (LABA); long-acting muscarinic antagonist (LAMA) plus LABA; ICS plus LAMA plus LABA.

As hundreds of wildfires burn in Canada, expert calls for climate action
Hundreds of wildfires continue to burn across Canada amid air quality concerns in several provinces. Estimates suggest 2025 is set to be one of Canada's worst wildfire seasons on record.
