FDA approves GSK's Nucala to treat COPD
The decision is supported by positive data from the Phase III MATINEE and METREX trials, which demonstrated a significant minimisation in the annualised rate of moderate/severe exacerbation rates among patients.
Nucala targets interleukin-5 (IL-5), a cytokine involved in type 2 inflammation.
Exacerbations in COPD are critical events that can lead to irreversible damage to the lungs, worsening of symptoms and increased likelihood of death.
The goal of COPD management is to prevent such exacerbations. During the trials, the incidence of adverse events was comparable between the antibody and placebo groups.
Mepolizumab is the only approved biologic that has been assessed in individuals with an eosinophilic phenotype marked by a blood eosinophil count (BEC) threshold as low as ≥150 cells/µL (microlitre).
BEC measures eosinophil levels captured through a blood test, which helps in indicating a patient's exacerbation risk.
GSK respiratory, immunology and inflammation research and development (R&D) global head and senior vice-president Kaivan Khavandi stated: 'The approval of Nucala in the US provides an important option for COPD patients.
'Long-term follow-up studies have demonstrated that exacerbations are the single most important predictor of future risk, with particularly poor outcomes in those requiring hospital visits or admissions.'
The antibody has not yet gained approval for COPD treatment in any other country, but regulatory submissions are being reviewed in Europe and China.
It has been developed to treat a range of IL-5-mediated conditions associated with type 2 inflammation, and is approved in Europe for four such conditions and in the US for five.
In April 2025, ABL Bio and GSK entered a global licensing agreement to develop treatments for neurodegenerative conditions.

FDA Warns Public Not to Eat Potentially Radioactive Shrimp
The Food and Drug Administration has warned the public not to consume certain frozen shrimp products sold at Walmart due to possible contamination with Cesium-137, a radioactive isotope. It said the warning affects the Great Value brand of raw frozen shrimp sold at the superstore, adding that anyone who purchased the product should dispose of it. A statement from the agency said the FDA was 'actively investigating reports of Cesium-137 (Cs-137) contamination in shipping containers and frozen shrimp products' in a shipment from Indonesia. It said that the U.S. Customs & Border Protection (CBP) had detected Cs-137 in shipping containers at four U.S. ports: Los Angeles, Houston, Savannah, and Miami. The FDA added that although it had not confirmed the presence of contamination in any commercial product in the United States, the shrimp products appear 'to have been prepared, packed, or held under insanitary conditions whereby it may have become contaminated with Cs-137 and may pose a safety concern.' 'If you have recently purchased raw frozen shrimp from Walmart that matches this description, throw it away. Do not eat or serve this product,' the FDA statement added. The FDA said limited exposure to Cs-137 can cause 'an elevated risk of cancer, resulting from damage to DNA within living cells of the body.' The FDA has recommended that Walmart recall this product. TIME has contacted Walmart for a response. This is a developing story.

FDA Suggest Walmart Recalls Frozen Shrimp After Radiation Detected At Port
The Food and Drug Administration is warning that some Great Value brand frozen shrimp sold at Walmart could be contaminated with radioactive isotope Cesium-137 after Customs and Border Protection detected the substance in shipping containers at four major American ports and at least one sample of shrimp. Cesium-137 was detected in some frozen shrimp coming from Indonesia—but none that have been sold in stores yet. getty The FDA is investigating the potential contamination and has not 'confirmed the presence of contamination in any product in commerce,' they are still warning consumers to avoid eating shrimp that come from the same Indonesian producer BMS Foods. The FDA is recommending Walmart recall frozen shrimp coming from BMS Foods, and the retailer has not returned a request for comment from Forbes. This is a breaking story and will be updated.

Walmart's Great Value shrimp has risk of radioactive contamination, FDA says
Some frozen shrimp sold at Walmart under the Great Value label are at risk of radioactive contamination and shouldn't be consumed, according to a warning from the U.S. Food and Drug Administration. The frozen shrimp were imported from Indonesian company PT. Bahari Makmur Sejati and sold at Walmart stores as Great Value brand frozen raw shrimp, the FDA said on Tuesday. The agency noted it has recommended that Walmart recall the product. Walmart didn't immediately respond to a request for comment. The shrimp could be contaminated with a radioactive isotope called Cesium-137, although the FDA said that no products as of yet have tested positive for it. The agency said it issued the warning about Walmart's Great Value shrimp after it had detected Cesium-137 in a single shipment of frozen shrimp from PT. Bahari Makmur Sejati. That shipment "did not enter U.S. commerce," the FDA said. Here's what to know about the warning. The FDA said that consumers "should not eat or serve certain lots of Great Value raw frozen shrimp from Walmart." The lots are: Consumers who bought the shrimp cited in the FDA's notice should throw it away, the agency said. "Distributors and retailers should dispose of this product and should not sell or serve this product," the FDA added. Cesium-137, or Cs-137, is the radioactive form of the element cesium, according to the U.S. Environmental Protection Agency. Produced by nuclear fission, it's used in medical devices and is also a byproduct of nuclear fission in nuclear reactors and weapons testing, the EPA notes. The Cesium-137 detected in the imported shrimp was about 68 Bq/kg, which the FDA said sits below its threshold of 1200 Bq/kg for "levels of concern" for imported foods. "At this level, the product would not pose an acute hazard to consumers," the FDA said in its warning notice. However, the FDA noted that repeated low-dose exposure to Cesium-137 carries an "elevated risk of cancer, resulting from damage to DNA within living cells of the body." It added, "Avoiding products like the shipment FDA tested with similar levels of Cs-137 is a measure intended to reduce exposure to low-level radiation that could have health impacts with continued exposure over a long period of time."
