Cisplatin (CIS) Administered As Dry Powder for Inhalation (DPI) in Patients with Stage IV Non-Small Cell Lung Cancer

ClinConnect Summary

This clinical trial is studying a new way to deliver a chemotherapy drug called cisplatin to patients with advanced lung cancer, specifically Stage IV Non-Small Cell Lung Cancer (NSCLC). Traditionally, cisplatin is given through an injection, which can cause serious side effects. In this trial, researchers are testing a method where cisplatin is delivered as a dry powder that patients inhale. The goal is to see if this inhaled delivery can effectively treat the cancer while reducing harmful side effects that often limit the use of higher doses.

To participate in this trial, you must be at least 18 years old and have been diagnosed with Stage IV NSCLC that hasn't been previously treated. Other key requirements include having measurable disease, a good performance status, and adequate organ function. If you join the study, you can expect to use a special inhaler to take the medication and attend regular check-ups to monitor your health and the effectiveness of the treatment. This trial is still recruiting participants, so if you or someone you know is interested, it could be an opportunity to explore a potentially new treatment option.

• • Patients who underwent major surgery within 4 weeks before the planned day for the first study treatment administration (D1).
• • Patients with EGFR activating mutation or ALK translocation, or any other activable molecular alterations that in the opinion of the investigator could be more effectively treated with targeted therapies (Note: This exclusion criterion must be checked before the first SoC administration).
• • Non-smoking patients without results of Epidermal growth factor receptor (EGFR) mutation and anaplastic large-cell lymphoma kinase (ALK) translocation before the planned day for the first study treatment administration (D1).
