Knopp Biosciences presenteert nieuwe fase 2-gegevens op AAAAI 2022 die aantonen dat orale dexpramipexol de luchtstroomobstructie verbetert, zoals gemeten door geforceerd expiratievolume (FEV1), grotendeels door het effect op de geforceerde vitale capaciteit (FVC)

Poster concludeert dat verandering in FEV1 gecorreleerd was met verandering in het absolute aantal eosinofielen in het bloed (AEC), wat het verband aantoont tussen eosinofielendepletie en klinisch voordeel

PITTSBURGH–(BUSINESS WIRE)– Knopp Biosciences LLC rapporteerde vandaag verdere klinische gegevens van de Fase 2 Exhale-studie die aantoont dat oraal dexpramipexol de luchtwegobstructie bij astma verbetert, zoals gemeten door FEV1, grotendeels door het effect op FVC. Verandering in FVC was de belangrijkste oorzaak van verhogingen van FEV1, wat suggereert dat dexpramipexol, door het verlagen van eosinofielen in het luchtweglumen, kan werken om slijmophoping en luchtinsluiting in kleine luchtwegen te verminderen. Zoals eerder gemeld, veroorzaakte dexpramipexol klinisch betekenisvolle verhogingen van FEV1 over de onderzoeksarmen en tijdstippen heen.

The data were presented over the weekend as a poster during the American Academy of Allergy Asthma & Immunology (AAAAI) meeting in Phoenix, AZ.

Knopp Biosciences Presents New Phase 2 Data at AAAAI 2022 Demonstrating That Oral Dexpramipexole Improves Airflow Obstruction as Measured by Forced Expiry Volume (FEV1), Largely Through Its Effect on Forced Vital Capacity (FVC)

Poster concludes that change in FEV1 was correlated with change in blood absolute eosinophil count (AEC), demonstrating the link between eosinophil depletion and clinical benefit

PITTSBURGH–(BUSINESS WIRE)– Knopp Biosciences LLC today reported further clinical data from its Phase 2 Exhale trial demonstrating oral dexpramipexole improves airflow obstruction in asthma as measured by FEV1, largely through its effect on FVC. Change in FVC was the dominant contributor to increases in FEV1, which suggests that by lowering eosinophils in the airway lumen, dexpramipexole may act to decrease mucus plugging and air trapping in small airways. As previously reported, dexpramipexole produced clinically meaningful increases in FEV1 across study arms and time points.

The data were presented over the weekend as a poster during the American Academy of Allergy Asthma & Immunology (AAAAI) meeting in Phoenix, AZ.

Eosinophils, a type of white blood cell, are a validated therapeutic target in asthma, as evidenced by the regulatory approval of multiple eosinophil-lowering biologics. Treatments approved to date for eosinophilic asthma are monoclonal antibodies requiring injection or infusion; dexpramipexole is administered orally.

“These results provide new insight into the effects of eosinophils on pulmonary physiology, and further strengthen the hypothesis that reductions in blood and tissue eosinophils by dexpramipexole are associated with improved lung health,” said Calman Prussin, M.D., Chief Medical Officer of Knopp.

As previously reported, dexpramipexole was well tolerated in the EXHALE trial, with 97% of dexpramipexole-treated patients completing the primary assessment phase. There were no serious adverse events and no adverse events leading to discontinuation.

“We are excited to be rapidly moving into Phase 3 clinical development, with the goal of securing regulatory approvals from health authorities around the world, and provide a first-in-class oral therapeutic option for millions of eosinophilic patients,” said Michael Bozik, M.D., CEO of Knopp.

ABOUT DEXPRAMIPEXOLE

Dexpramipexole, a selective inhibitor of eosinophil maturation, is an oral small molecule drug in development by Knopp for asthma and other eosinophil-associated diseases. In hypereosinophilic syndrome, dexpramipexole has previously been shown in a Phase 2 trial to significantly reduce requirements for oral corticosteroids and in a subset of patients to produce durable disease remission. In its earlier development in amyotrophic lateral sclerosis, dexpramipexole was shown to be well tolerated in Phase 1, Phase 2, and Phase 3 trials comprising approximately 1,200 patients.
