Study Endpoints

Primary Endpoints

Time to first CompEx Asthma event
12 weeks

The CompEx Asthma is a composite endpoint for exacerbations that captures asthma-worsening episodes based on combination of diary events (worsening in daily PEF, asthma symptoms and rescue medication use) plus severe asthma exacerbation events. Diary events are defined by threshold and slope criteria using the following morning/evening diary variables: * PEF * Asthma symptom score (0 to 3) * Use of rescue medication

Frequently asked questions about AZD8630

What is AZD8630 used for in asthma?

AZD8630 is an investigational small molecule being developed for the treatment of asthma. It is administered via inhalation and is being studied in adults and adolescents with asthma, including those with uncontrolled asthma at risk of exacerbations.

Who is developing AZD8630?

AZD8630 is being developed by AstraZeneca PLC, a biopharmaceutical company listed on the stock exchange under the ticker symbol AZN. The company is conducting clinical trials to evaluate the safety, tolerability, and efficacy of this investigational drug in patients with asthma.

What phase is AZD8630 in?

AZD8630 is currently in Phase 2 clinical development for asthma. A Phase 2 dose range-finding study has been completed, and the drug remains investigational, meaning it has not yet been approved by regulatory authorities. Earlier Phase 1 studies have also been completed.

What clinical trials is AZD8630 in?

AZD8630 has been studied in four completed clinical trials. These include NCT05110976, a Phase 1 study in healthy subjects and asthma patients; NCT06529419, a Phase 2 dose range-finding study in adults with uncontrolled asthma; NCT06795906, a Phase 1 safety and pharmacokinetic study; and NCT07065331, a Phase 1 study in adolescents with asthma.

Is AZD8630 the same as any other drug?

AZD8630 is the sole name provided for this investigational drug. No alternative names have been reported in the clinical trial information. It is a distinct small molecule being developed by AstraZeneca for asthma.
