Welcome to our dedicated page for AstraZeneca SEC filings (Ticker: AZNCF), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
The AZNCF SEC filings page on Stock Titan provides access to AstraZeneca PLC regulatory disclosures as furnished to the U.S. Securities and Exchange Commission. AstraZeneca uses Form 6-K reports to share information on clinical trial results, regulatory milestones and portfolio updates for its prescription medicines in Oncology, Rare Diseases and BioPharmaceuticals, including Cardiovascular, Renal & Metabolism, and Respiratory & Immunology.
Recent 6-K filings show the depth of information available to investors and researchers. One report details the KOMET Phase III trial of Koselugo (selumetinib) in adults with neurofibromatosis type 1 and symptomatic, inoperable plexiform neurofibromas, supporting a positive opinion from the European Medicines Agency’s CHMP. Another filing summarises the WAYPOINT Phase III trial of Tezspire (tezepelumab) in chronic rhinosinusitis with nasal polyps, including co-primary endpoints on nasal polyp score and nasal congestion.
Additional 6-Ks provide high-level data from the TULIP-SC Phase III trial of Saphnelo (anifrolumab) in systemic lupus erythematosus and an update on the RESOLUTE Phase III trial of Fasenra (benralizumab) in chronic obstructive pulmonary disease. These documents also restate AstraZeneca’s standard company description, outlining its global footprint, therapeutic focus and Respiratory & Immunology franchise.
On Stock Titan, users can review these filings as they are made available from EDGAR and use AI-powered summaries to understand the key points of each document, such as trial design, primary and secondary endpoints, safety profiles and regulatory implications, without reading every technical detail.
AstraZeneca reported positive interim Phase III results from the global I CAN trial of Ultomiris (ravulizumab) in adults with immunoglobulin A nephropathy (IgAN) at risk of disease progression. Ultomiris met the primary interim endpoint, showing a statistically significant and clinically meaningful reduction in proteinuria at week 34, with rapid effects seen as early as week 10.
The trial will continue to week 106 to assess change in estimated glomerular filtration rate (eGFR) and longer-term kidney outcomes. The safety profile was consistent with the known profile of Ultomiris, and AstraZeneca plans to seek accelerated approval in key markets and present full data at a medical meeting.

AstraZeneca reported that its IL-33-targeting biologic tozorakimab met the primary endpoint in the Phase III MIRANDA trial in chronic obstructive pulmonary disease (COPD). The drug produced a statistically significant and clinically meaningful reduction in the annualised rate of moderate-to-severe COPD exacerbations in former smokers and in the overall trial population.
This is the third positive pivotal Phase III trial for tozorakimab in COPD, following the OBERON and TITANIA studies, reinforcing evidence of benefit on top of standard inhaled therapies. Tozorakimab 300mg every two or four weeks was generally well tolerated with a favourable safety profile consistent with earlier trials, and the data will be submitted to regulatory authorities and shared at an upcoming medical meeting.

AstraZeneca reported positive Phase III results from the EMERALD-3 trial in earlier-stage, unresectable hepatocellular carcinoma eligible for embolisation. The regimen combining Imfinzi (durvalumab), Imjudo (tremelimumab), lenvatinib and transarterial chemoembolisation (TACE) achieved a statistically significant and clinically meaningful improvement in progression-free survival versus TACE alone.
At an interim analysis, the combination also showed a trend toward improved overall survival, and a STRIDE regimen plus TACE arm showed strong trends for both progression-free and overall survival, although not yet formally tested. Safety was consistent with known profiles, and the trial will continue to follow overall survival and other secondary endpoints while data are shared with global regulators.

AstraZeneca, through its Alexion rare disease unit, reported positive global Phase III results for efzimfotase alfa (ALXN1850), an investigational enzyme replacement therapy for hypophosphatasia (HPP).
In children who had never received Strensiq, the MULBERRY trial met its primary endpoint, showing statistically significant and clinically meaningful bone health improvements on the Radiographic Global Impression of Change score at week 25, with supportive gains in rickets severity and physical function measures. The CHESTNUT switch study in paediatric patients previously treated with Strensiq showed efzimfotase alfa was well-tolerated and maintained bone benefits while offering less frequent dosing.
In adolescents and adults, the HICKORY trial did not achieve statistical significance on the primary Six-Minute Walk Test endpoint versus placebo, largely due to better-than-expected placebo performance in adult-onset HPP, but showed nominally significant benefits in fatigue and in prespecified subgroups with paediatric-onset HPP across mobility, function and pain. Across all three studies, efzimfotase alfa demonstrated an acceptable safety profile, and AstraZeneca plans to present the data at a medical meeting and share them with global regulators.

AstraZeneca reported that its investigational biologic tozorakimab met the primary endpoint in both Phase III OBERON and TITANIA trials in patients with COPD. The drug significantly reduced the annualised rate of moderate-to-severe COPD exacerbations versus placebo in former smokers and in the overall population, on top of inhaled standard of care.
Tozorakimab is a potential first-in-class monoclonal antibody targeting IL‑33, uniquely blocking both reduced and oxidised forms to address inflammation and mucus dysfunction. It was generally well tolerated with a favourable safety profile. Additional Phase III COPD trials, PROSPERO and MIRANDA, are ongoing with results expected in H1 2026.
