Første-i-mennesker-forsøg til vurdering af REGN20423 hos raske voksne deltagere og voksne deltagere med atopisk dermatitis (AURA-AD)
Et to-delt fase 1, randomiseret, dobbeltblindt, placebo-kontrolleret første-på-mennesker-studie til vurdering af sikkerhed, tolerabilitet, farmakokinetik og immunogenicitet af REGN20423 hos raske voksne deltagere og voksne deltagere med atopisk dermatitis
This study will test an experimental study medicine called REGN20423 to see how effective it is in healthy participants (in Part A) and participants with atopic dermatitis (eczema) (in Part B). REGN20423 is a study medicine that is only used in clinical studies. REGN20423 has not previously been studied in humans.
The study is looking at:
- What side effects REGN20423 might cause
- How much REGN20423 is in the blood at different times
- How well REGN20423 works in adults with atopic dermatitis
- Whether the body makes antibodies against REGN20423
- How the body changes after having REGN20423, which can help researchers understand why REGN20423 works better in some people than others
- What the best dose of REGN20423 is

Planlægger du at dele individuelle deltagerdata (IPD)?
IPD-planbeskrivelse
All Individual Patient Data (IPD) that underlie publicly available results will be considered for sharing
IPD-delingstidsramme
When Regeneron has:
- received marketing authorization from major health authorities (e.g., FDA, European Medicines Agency (EMA), Pharmaceuticals and Medical Devices Agency (PMDA), etc.) for the product and indication or has globally discontinued development of the product for all indications on or after April 2020 and has no plans for future development
- made the study results publicly available (e.g., scientific publication, scientific conference, clinical trial registry)
- the legal authority to share the data, and
- ensured the ability to protect participant privacy
IPD-delingsadgangskriterier
Qualified researchers can submit a proposal for access to individual patient or aggregate level data from a Regeneron-sponsored clinical trial through Vivli. Regeneron's Independent Research Request Evaluation Criteria can be found at: https://www.regeneron.com/sites/default/files/Regeneron-External-Data-Sharing-Policy-and-Independent-Research-Request-Evaluation-Criteria.pdf
