Pain, Postoperative
Conditions
Brief summary
This study focused on ND-340 extended release injection suspension for patients undergoing total knee arthroplasty with a one-time nerve blockade to assess drug side effects, pharmacokinetics and the effect of pain relief after surgery.
Interventions
DRUGND-340
ND-340: Subjects will receive a single administration of ND-340 at the specified dose in each arm after TKA.
DRUGIV-PCA
IV-PCA: Intravenous patient-controlled analgesia (IV-PCA), morphine, will be administered in subjects of control group after TKA for postoperative pain management as standard practice.

Current or historical evidence of any clinically significant disease or condition, especially terminal stage cancer, poorly controlled diabetic mellitus (i.e., HbA1c \> 8%), or neurological disease that, in the opinion of the investigator, may increase the risk of study treatment and TKA, or complicate the subject's post-operative course or interfere with the determination of pain intensity related solely to the TKA 20. Subject with severe heart diseases (NYHA class-III and IV), with ischemic heart diseases (angina pectoris and myocardial infarction) and subject who underwent percutaneous transluminal coronary angioplasty (PTCA) or had treatments for coronary artery bypass graft within 6 months prior to screening 21. With pre-existed psychiatric or neurological deficits, which may compromise the neurological toxicity evaluations in this study by the investigator's judgment 22. With stroke within 1 year prior to screening 23. With bone cancer within 5 years prior to screening 24. Inability to understand or operate the PCA machine 25. Female subject who is breast-feeding, pregnant, or planning to become pregnant
