Study Endpoints

Primary Endpoints

Within-individual % Change in Plasma Desmosine/Isodesmosine
baseline, week 12

To evaluate the effect of alvelestat (MPH966) administered twice daily (bid) for 12 weeks on blood markers of within-individual % change in plasma desmosine/isodesmosine will be measured.

Frequently asked questions about Alvelestat

What is Alvelestat used for?

Alvelestat is an investigational oral small molecule being studied for alpha 1-antitrypsin deficiency, a rare genetic condition that can lead to emphysema and COPD. It has also been studied in COVID-19. It is not yet approved and remains in clinical development.

What does Alvelestat target?

Alvelestat targets ELANE, the gene encoding neutrophil elastase. It is an inhibitor of this enzyme. In alpha 1-antitrypsin deficiency, loss of elastase inhibition is central to lung tissue destruction, so blocking neutrophil elastase is the intended mechanism of the drug.

Who is developing Alvelestat?

Alvelestat is being developed by Mereo BioPharma Group plc, which trades under the ticker MREO. The company holds the development program for the drug across its rare disease and COVID-19 indications.

What phase is Alvelestat in?

Alvelestat is in Phase 2 clinical development. It is investigational and has not been approved by the FDA. The program has received FDA Orphan Drug and Fast Track designations, which are intended to support and expedite development of therapies for serious conditions.

What clinical trials is Alvelestat in?

Alvelestat has been studied in completed trials including NCT03679598, a Phase 2 study in alpha 1-antitrypsin deficiency, NCT03636347, a 12-week Phase 2 study in alpha 1-antitrypsin-related COPD, and NCT04539795, a Phase 1 COVID-19 safety and tolerability study. These trials enrolled 63, 99, and 15 participants respectively.

Is Alvelestat the same as MPH966?

Yes. Alvelestat is also known as MPH966, and the two names refer to the same compound. It has additionally been catalogued as Alvelestat oral tablet dose 1 and Alvelestat dose 1. Searches for any of these names point to the same investigational drug developed by Mereo BioPharma.
