During the study, participants will be assigned to receive either depemokimab or a placebo through a subcutaneous injection, which is a shot given just under the skin. The study is designed so that neither the participants nor the researchers know which treatment is being administered. This approach helps ensure that the results are as accurate as possible.

Participants will take the study drug by mouth every day for several months, with regular visits to check for any side effects and to answer simple questionnaires. Researchers will monitor for any new health problems, serious problems, and specific symptoms related to the study drugs. They will also use a few rating tools to watch for movement‑related side effects and to assess thoughts of self‑harm, using the C-SSRS questionnaire and movement scales called the SAS, BARS, and AIMS. The study ends after the treatment period and a short follow‑up to confirm the safety findings.

The purpose of the study is to see if the new combination can keep the cancer from getting worse for a longer time than the standard treatments. Participants are randomly assigned to receive either the new three‑drug regimen or the standard therapy, and they take the medicines in repeated cycles while visiting the clinic for regular check‑ups and imaging scans. The main result being measured is progression‑free survival (PFS), which means the time until the cancer grows or the patient dies, and it is evaluated using standard imaging rules called RECIST and analyzed with the Kaplan‑Meier statistical method. Safety and side‑effects are recorded and graded according to the CTCAE system.

Participants will receive one of the two treatments for a 12‑week period and then switch to the other treatment for another 12‑week period. The design is double‑blind, meaning neither the participants nor the study staff know which inhaler is active, and a double‑dummy approach ensures each person uses two inhalers (one containing the active drug and one containing a placebo) so the experience is the same. During the study, lung function is measured with a test called FEV1, which assesses how much air can be exhaled in one second, and participants complete a short questionnaire about asthma control called ACQ‑5 and another questionnaire about quality of life called PAQLQ. Safety is monitored by recording any side effects and by checking basic blood tests and other routine examinations.

The main goal of the trial is to learn how safe the medicine is and how well patients can tolerate increasing doses. Participants will receive the drug in a series of treatment cycles that last about four weeks each, with the amount of medicine gradually increased in early groups to find the highest dose that can be given without unacceptable side effects.

During the study, patients will have regular check‑ups, blood tests, and scans to watch for any side effects and to see how the cancer responds. Any problems that arise will be recorded and managed by the medical team, and the study will continue until the predetermined number of treatment cycles is completed or if a participant chooses to stop early.

The purpose of the trial is to find out whether adding orelabrutinib to the usual regimen can keep the disease from getting worse for a longer period of time. After a screening visit, participants are randomly assigned to one of the two groups, and neither the participants nor the doctors know which group they are in. Treatment is given in repeated cycles over several months, with regular check‑ups that include blood tests, heart checks, and questionnaires about quality of life. The study follows participants for several years to see how long they stay free of disease progression and to monitor safety.
