Langsigtet vurdering af sikkerhed og effekt af subkutan amlitelimab hos voksne deltagere med moderat til svær astma, som afsluttede behandlingsperioden for tidligere amlitelimab astma klinisk undersøgelse (RIVER-ASTHMA)
En langsigtet forlængelsesundersøgelse til evaluering af den langsigtede sikkerhed, tolerabilitet og effektivitet af subkutan amlitelimab hos voksne deltagere med moderat til svær astma, der fuldførte behandlingsperiode for tidligere amlitelimab astma klinisk undersøgelse
This is a study of amlitelimab for the treatment of participants with moderate-to-severe asthma. The study will have a double-blind treatment period until Week 24 for each participant and an open-label treatment period where each participant will receive open-label amlitelimab from Week 24 onwards. The purpose of this study is to evaluate long-term safety, tolerability, and efficacy of amlitelimab for the treatment of adult participants with moderate-to-severe asthma who have previously been enrolled and completed the treatment period of the parent study. The study duration will be up to 156 weeks. The treatment duration will be up to 144 weeks. The number of visits will be 18.

Change from parent study baseline in Asthma Control Questionnaire (ACQ)-5, ACQ-6, and ACQ-7 scores
Tidsramme: From parent study baseline up to Week 144 (EOT of LTS17510)
|
The ACQ is a validated questionnaire that measures the adequacy of asthma control and any changes in asthma control that may occur spontaneously or as a result of treatment. Each item of the ACQ is measured on a 7-point response scale (0=no impairment, 6=maximum impairment). The ACQ score is the mean of the item responses and ranges from 0 (totally controlled) and 6 (severely uncontrolled). |

Tidsramme: From baseline up to Weeks 144 (EOT of LTS17510)
|
The AQLQ(S) was designed as a self-administered participant reported outcome to measure the functional impairments that are most troublesome to adolescents and adults ≥12 years of age as a result of their asthma over the past two weeks. The instrument is comprised of 32 items, each rated on a 7-point Likert scales from 1 to 7. |
