Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Pharmacodynamic, Therapy, Pharmacokinetic, Efficacy, Pharmacoeconomic, Safety

To evaluate the efficacy of lunsekimig as measured by the annualized rate of moderate to severe chronic obstructive pulmonary disease (COPD) exacerbations

Secondary objectives 7

1. • To evaluate the efficacy of lunsekimig on lung function
2. • To evaluate the efficacy of lunsekimig on health related quality-of-life
3. • To evaluate the efficacy of lunsekimig on symptoms and disease burden
4. • To evaluate the efficacy of lunsekimig on moderate or severe COPD exacerbations
5. To evaluate the safety of lunsekimig
6. • To evaluate the pharmacokinetics of lunsekimig
7. • To evaluate the immunogenicity of lunsekimig

Conditions and MedDRA coding

Plan to share IPD

Yes

IPD plan description

Qualified researchers may request access to patient level data and related study documents including the clinical study report, study protocol with any amendments, blank case report form, statistical analysis plan, and dataset specifications. Patient level data will be anonymized and study documents will be redacted to protect the privacy of trial participants.
