What is this study?

This is a parallel, Phase 2b/Phase 3, 3-arm study to investigate the efficacy, safety, and tolerability of subcutaneous (SC) treatment with lunsekimig compared with placebo in adult participants (aged 40 to 80 years, inclusive) with inadequately controlled Chronic obstructive pulmonary disease (COPD) characterized by an eosinophilic phenotype. Participation to the study consists of 3 periods: * Screening period of up to 4 weeks * Randomized intervention period of approximately 48 weeks * Follow-up period: Approximately 8 weeks The study duration will be up to 60 weeks.

It is , overseen by an independent and licensed medical staff.

🚫 You may not be able to join if…

  • Asthma, including asthma-COPD overlap (ACOS)
  • A significant lung disease other than COPD
  • Need long-term oxygen above 4.0 L/min, or need more than 2.0 L/min to keep oxygen saturation above 88% at rest

  • !Some conditions may not be a fit: Asthma

What to expect, step by step

  1. 1

    Usually a few weeks

    The study team checks whether the study is a good fit for you, with a visit and sometimes lab tests. You can ask any questions before deciding.

  2. 2

    Treatment

    If you join and choose to continue, you receive the study treatment and are watched closely by medical staff.

  3. 3

    Follow-up

    After treatment, the team checks on your health and confirms the visit schedule with you. You can leave the study at any point.

Has this treatment been tested before?

Yes. This treatment has already been through earlier human studies for safety before reaching this stage.

What you need to know before you apply

What is this study testing?+

This is a parallel, Phase 2b/Phase 3, 3-arm study to investigate the efficacy, safety, and tolerability of subcutaneous (SC) treatment with lunsekimig compared with placebo in adult participants (aged 40 to 80 years, inclusive) with inadequately controlled Chronic obstructive pulmonary disease (COPD) characterized by an eosinophilic phenotype. Participation to the study consists of 3 periods: * Screening period of up to 4 weeks * Randomized intervention period of approximately 48 weeks * Follow-up period: Approximately 8 weeks The study duration will be up to 60 weeks.

Is it safe? Who makes sure of that?+

This is a late-stage study (Phase 3), testing how well the treatment works in more people. Every study is reviewed and monitored by an independent ethics board (called an IRB) whose job is to protect participants, and care is overseen by licensed medical staff. You'll be told the known risks before you agree to anything, and you can stop at any time.

Will I get a placebo instead of the real treatment?+

Some studies compare a treatment against a placebo (an inactive version), and some don't. If this one does, the study team will explain your chances of receiving the active treatment before you decide. Nothing is hidden from you.

Do I have to stop taking my current medications?+

It depends on the study. Some let you stay on your current medications and some ask you to adjust them. Never stop a medication on your own — the study team will review everything with you first.

Does it cost anything? Will I be paid?+

The study treatment and study-related visits are provided at no cost to you. Some studies also pay for your time; the coordinator can tell you if this one does. You should never be asked to pay to take part.

Do I need insurance? Will anyone ask about my immigration status?+

No. You do not need health insurance to take part in a research study, and you will not be asked about your immigration status to join. Taking part is about whether you're a medical fit for the study.

What if English isn't my first language?+

You have the right to understand everything before you agree. Study sites can often provide materials or an interpreter in your language — you can ask the coordinator for one.

Is my information private?+

Yes. Your health information is only shared with the study sites you choose to be contacted by, and only to help match and enroll you. It is never sold, and you can ask us to delete it at any time.
