The primary endpoint will be assessed in the primary population (former smokers with symptomatic COPD and a history of exacerbations, on optimised treatment with maintenance inhaled therapy \[triple therapy, or dual therapy if triple is not considered appropriate\]).
The primary efficacy endpoint is the rate of severe COPD exacerbations.
To evaluate the effect of tozorakimab versus placebo as an add on to Standard of Care (SoC) in participants with viral lung infection requiring supplemental oxygen on the prevention of death or progression to IMV/ECMO.

The rate ratio of severe asthma exacerbations will be assessed in the participants with uncontrolled moderate-to-severe asthma and ≥ 1 severe exacerbation within 12 months prior to screening.

Tozorakimab is an investigational antibody being studied for respiratory conditions including asthma, chronic obstructive pulmonary disease (COPD), viral lung infection and acute respiratory failure. It is also used in healthy participant trials to evaluate bioavailability and pharmacokinetics of different dosage forms.
Tozorakimab is being developed by AstraZeneca PLC, a biopharmaceutical company traded under the ticker AZN. The drug is currently in clinical development across multiple studies sponsored by the company.
Tozorakimab is in Phase 2 clinical development for COPD, with additional trials in Phase 1 for healthy participants and a Phase 3 trial for viral lung infection. It remains investigational and is not yet approved by regulatory authorities.
Tozorakimab has been studied in several trials including NCT05624450, a Phase 3 study in patients hospitalised for viral lung infection requiring supplemental oxygen, and NCT06897748, a Phase 2 study in COPD patients with elevated eosinophils. Other trials include NCT06304961 and NCT06908577 in healthy volunteers.
Yes, Tozorakimab is also known as Tozorakimab Dose Regimen 1. This alternative name appears in clinical trial documentation to distinguish specific dosing schedules being evaluated in studies.
Tozorakimab is a monoclonal antibody, indicated by its -mab suffix, designed to target specific pathways involved in respiratory inflammation. As an antibody therapeutic, it is administered via subcutaneous injection and is being evaluated for its ability to modulate immune responses in conditions like COPD and viral infections.
