Brief Summary
Primary Objectives: To evaluate the safety and tolerability of single and multiple ascending doses of OsrhCT administered intrathoracically in patients with pleurisy, and to explore the DLT, MTD, and recommended effective dose of OsrhCT. Secondary Objectives: To evaluate the preliminary efficacy of single and multiple intrathoracic doses of OsrhCT. Population: Patients diagnosed with pleurisy requiring chest tube drainage. Investigational Products: Investigational Drug: Recombinant Human Chymotrypsin (OsrhCT), provided by Wuhan Healthgen Biotechnology Corporation, 4,000U/vial, freeze-dried powder, stored at 2-8°C. Placebo: Placebo for Recombinant Human Chymotrypsin (OsrhCT), provided by Wuhan Healthgen Biotechnology Corporation, freeze-dried powder, stored at 2-8°C. Study Design: The study comprises two parts: Single Ascending Dose (SAD) and Multiple Ascending Dose (MAD), both employing a multicenter, randomized, double-blind, and placebo-controlled design. Sample Size: A total of 72 subjects (both male and female) are expected to be enrolled in this trial, including 48 subjects for single-dose administration and 24 subjects for multiple-dose administration.

Recombinant Human Chymotrypsin(OsrhCT)
EXPERIMENTALRecombinant Human Chymotrypsin (OsrhCT), freeze-dried powder, 4,000U/vial Single Ascending Dose (SAD) Study: 20ml of the prepared drug will be injected into the thoracic cavity through a chest tube.There are six dose groups (2000U, 4000U, 8000U, 12000U, 16000U, 20000U),each subject can only receive administration in one dose group, and repeated administration is not allowed. Multiple Ascending Dose (MAD) Study: 20ml of the prepared drug will be injected into the thoracic cavity through a chest tube.three dose groups (low, medium, and high) will be selected for multiple dosing. Each subject will receive only one dose group and no repeat dosing.
