Cardiff Oncology shares plunge after Q2 earnings miss
Today, GSK plc (LSE/NYSE: GSK), a prominent pharmaceutical company with a market capitalization of $76.46 billion and impressive gross profit margins of 71.81%, shared promising results from two pivotal phase III trials, ANCHOR-1 and ANCHOR-2, highlighting the efficacy and safety of depemokimab in treating chronic rhinosinusitis with nasal polyps (CRSwNP). According to InvestingPro analysis, GSK maintains a GREAT financial health score, positioning it well for continued R&D investments. The trials met their primary endpoints, demonstrating significant improvements in nasal polyp size and obstruction with twice-yearly dosing of depemokimab compared to placebo.
The findings, presented at the 2025 American Academy of Allergy, Asthma and Immunology/World Allergy Organization Joint Congress and published in The Lancet, indicated that the benefits of depemokimab were observed early and sustained over a 52-week period. The treatment, an investigational ultra-long-acting monoclonal antibody targeting interleukin-5 (IL-5), a key cytokine in type 2 inflammation, showed a treatment difference in nasal polyp score and mean nasal obstruction scores.
Patients in the studies, which included a broad demographic reflective of real-world clinical practice, experienced reductions in disease severity by the first assessment, which continued through week 52. Secondary endpoints also showed nominal improvements in symptoms and quality of life measures.
Kaivan Khavandi, SVP and Global Head of Respiratory, Immunology/Inflammation R&D at GSK, highlighted the medical need for sustained symptom improvement in CRSwNP, noting the potential of depemokimab as an ultra-long-acting treatment option.
Adverse events (AEs) reported in the trials were consistent with previous studies and were similar between the depemokimab and placebo groups. Serious adverse events were not considered related to the study treatment.
CRSwNP affects up to 4% of the general population, often leading to surgeries and long-term systemic corticosteroid use, which comes with risks of serious adverse events. Depemokimab’s twice-yearly dosing regimen could offer a new approach to managing this chronic condition. With annual revenues of $39.28 billion and a steady dividend yield of 4.18%, GSK demonstrates strong commercial capabilities to potentially maximize this opportunity.
The data from ANCHOR-1 and ANCHOR-2, along with results from other trials, will support regulatory filings for depemokimab in various countries. However, depemokimab is not yet approved for CRSwNP or asthma with type 2 inflammation in any country.
