• Health condition(s) or Problem(s) studied: progressive fibrosing interstitial lung disease
• Date of first enrollment: 20/02/2023
• Target sample size: 10
• Study type: Interventional
• Intervention(s): Take 0.2 g of disulfiram once a day from the start of administration to the end of administration.

Outcome(s)

• Primary Outcome: Frequency of Grade 2 or higher adverse events

Secondary Outcome

1. Percent change in FVC decrease (ml/year)
2. Percent Change in DLco Predicted Decline (%/year)
3. Changes in various symptoms using patient questionnaires
4. Changes in serum transaminases and serum creatinine
5. Frequency of Grade 2 or higher side effects
6. Evaluation of interstitial lung disease status by the physician.

Key inclusion & exclusion criteria

- A relative decline in the %FVC of 5% to less than 10% of the predicted value and worsening of respiratory symptoms.
- A relative decline in the %FVC of 5% to less than 10% of the predicted value and an increased extent of fibrosis on chest imaging.
- Worsening of respiratory symptoms and increased fibrotic changes on chest imaging.
2. Age: Those who are between 18 and less than 80 years old at the time of obtaining consent.
3. Gender: Any gender.
4. Those with respiratory function test results (FVC, DLco) performed at least 3 months prior to obtaining consent.
