ClinConnect Summary

This clinical trial is testing a new vaccine called BMD006, which is designed to help treat advanced lung cancer and lung metastasis (cancer that has spread to the lungs from other parts of the body). The vaccine is inhaled as a dry powder and contains genetic material (mRNA) that helps the body recognize and fight cancer. This trial is open to adults aged 18 to 75 who have advanced lung cancer or solid tumors that have spread to the lungs, and who have not responded to standard treatments or have no other treatment options available. Participants will need to provide tumor samples and be able to participate fully in the study, including understanding and signing consent forms.

If you join this study, you will receive the BMD006 vaccine along with a possible combination with another treatment called PD-1 therapy. The trial aims to see how safe the vaccine is, how well it works, and how the body processes it. Participants will be closely monitored for any side effects and overall health during the trial. It's important to note that there are specific health criteria to be eligible, such as having no other serious health issues and not having received certain recent treatments. If you meet these criteria, this trial may offer a new option in the fight against lung cancer.

• • Expected life expectancy ≥12 weeks.
• • Female patients of childbearing potential and male patients (and their female partners) must use highly effective contraception from the screening period until at least 6 months after the last dose of the study drug. Patients must not plan to conceive, donate sperm, or donate eggs during this period
• Exclusion Criteria:
• • Patients with lung cancer who have concurrent other types of malignant tumors or are diagnosed with multiple primary malignancies, except for the following: completely resected basal cell carcinoma and squamous cell carcinoma of the skin, completely resected any type of carcinoma in situ.
• • Symptomatic central nervous system metastasis; for patients with asymptomatic brain metastasis or those whose symptoms have been stable for ≥2 weeks after treatment of brain metastasis, they may participate in this study if they meet all the following criteria: measurable lesions in the lungs; cessation of steroid treatment 14 days prior to the first trial product dose.
• • Patients with chronic obstructive pulmonary disease (COPD), asthma, or allergies to pollen or dust.
• • Patients suspected of having active or latent tuberculosis infection, based on interferon-γ release assay results, clinical symptoms, and/or chest imaging findings (patients with evidence of adequately treated prior active tuberculosis infection may be enrolled after assessment by the investigator; for latent tuberculosis, patients must have completed at least 4 weeks of anti-tuberculosis treatment, with no liver function impairment \[ALT ≤3×ULN, AST ≤3×ULN\], and after the investigator assesses that the risk is manageable, they may be considered for continued screening or enrollment).
• • History of interstitial lung disease (e.g., idiopathic pulmonary fibrosis or organizing pneumonia), or active, non-infectious pneumonia requiring immunosuppressive treatment such as corticosteroids.
• • Patients with active autoimmune diseases requiring therapeutic intervention.
• • History of serious bleeding disorders; or those with coagulation dysfunction (as indicated by laboratory tests or medical history) who are deemed by the investigator to be unsuitable for the trial treatment.
• • History or current diagnosis of cardiovascular disease, including any of the following: a) Recent myocardial infarction or coronary artery bypass grafting (CABG) within the past 6 months; b) Uncontrolled congestive heart failure; c) Unstable angina (within the past 6 months); d) Clinically significant (symptomatic) arrhythmias (e.g., sustained ventricular tachycardia, clinically significant second- or third-degree atrioventricular block without a pacemaker).
• • Clinically uncontrolled third-space fluid accumulation (e.g., pleural effusion/pericardial effusion; patients with effusions that do not require drainage or those whose effusions have not increased significantly after stopping drainage for 3 days may be included).
• • Severe infection requiring intravenous antibiotic treatment or hospitalization at screening, or any uncontrolled active infection within 4 weeks prior to the first dose of the trial product.
• • History of severe allergic reactions, or known allergy to any active or inactive component of BMD006 or PD-1 inhibitors.
