Intrapleural TolueneSulfonamide in malignant pleural effusion: early safety and activity
Official title: First-in-Human Expanded Cohort Study of Intrapleural Administration of TolueneSulfonamide in Patients With Malignant Pleural Effusion
Run by China-Japan Friendship Hospital · NCT07332858 · Data updated 2026-11-12
This study tests intrapleural injections of TolueneSulfonamide in adults with malignant pleural effusion to see if it is safe and could help reduce the effusion.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–75 with NSCLC-related malignant pleural effusion, ECOG 0–2, symptomatic dyspnea, and no recent intrathoracic drug treatment.
✕Probably not a fit
Patients with rapidly advancing disease, poor performance status, or non-responsiveness to intrapleural therapy may not benefit.

What this trial studies
This is a first-in-human expansion study with two parts. Part 1 assesses safety and explores dose options for intrapleural TolueneSulfonamide in patients with malignant pleural effusion due to non-small cell lung cancer. Part 2 evaluates clinical activity and efficacy in a multicenter, randomized design comparing TolueneSulfonamide plus catheter drainage to catheter drainage with saline. The trial progresses from a single-arm safety phase to a double-blind, controlled phase after establishing safety. Patients will be followed for safety and preliminary signs of benefit related to pleural effusion control.
Why it matters
Potential benefit: If successful, the treatment could lessen pleural buildup and improve breathing and quality of life for patients with malignant pleural effusion.
How similar studies have gone: Early-stage intrapleural therapies have shown variable safety and signals of activity in pleural malignancies, but this is a first-in-human evaluation of TolueneSulfonamide in this setting.

Show full inclusion / exclusion criteria
Inclusion Criteria: 1. Age between 18 and 75 years (inclusive) at the time of signing the informed consent form. 2. Histologically or cytologically confirmed malignant pleural effusion, with the primary tumor diagnosed as non-small cell lung cancer (NSCLC). 3. Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, with an expected survival of at least 3 months. 4. Presence of dyspnea symptoms. 5. No prior local thoracic treatment within 1 month before enrollment, including intrapleural drug administration or thoracic radiotherapy (diagnostic thoracentesis is permitted). 6. Except for the subject's current stable systemic anti-tumor therapy, any other ongoing tumor-related treatments must be suspended or discontinued after evaluation by the investigator to ensure they do not interfere with the assessment of PTS treatment. 7. Fully understands the study objectives and procedures, agrees to participate in the study, and provides written informed consent. Exclusion Criteria: 1. History of allergy or hypersensitivity to PTS or any of its excipients. 2. Presence of uncontrolled intrapleural infection or severe loculated pleural effusion that is difficult to manage. 3. Participation in another interventional clinical study within 3 months prior to enrollment (diagnostic studies are excluded). 4. Severe organ dysfunction, including but not limited to coagulation disorders, congestive heart failure, malignant arrhythmias, coronary artery disease requiring long-term medication, valvular heart disease, myocardial infarction, or refractory hypertension; severe cardiac, hepatic, or renal insufficiency, or active bleeding or thrombotic risk. 5. Presence of uncontrolled infectious wounds. 6. Pregnant or breastfeeding women. 7. Any other condition that, in the investigator's judgment, makes the subject unsuitable for participation in this study. 8. Criteria for withdrawal from the study.
