Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Compare the change from baseline in Average Daily Pain Score(ADPS) between HSK16149 and placebo at week 5.	The mean change in average daily pain score (ADPS) was measured using a 11-point numeric rating scale (NRS; 0 [no pain] to 10 [worst possible pain]. The rating averaged over a 7-day period and was based on entries in patients' daily pain diaries.	Baseline and week 5
Primary	Compare the change from baseline in Average Daily Pain Score (ADPS) between HSK16149 and placebo at week 13.	The mean change in average daily pain score (ADPS) was measured using a 11-point numeric rating scale (NRS; 0 [no pain] to 10 [worst possible pain]. The rating averaged over a 7-day period and was based on entries in patients' daily pain diaries.	Baseline and week 13
Secondary	Compare the response rate between HSK16149 and placebo at week 5 (Proportion of subjects whose ADPS decreased by =30% and =50% from baseline ).	Ratio of Participants Responding to Treatment, as Measured by Average Daily Pain Score (ADPS) Reduction from Baseline. The ADPS is used to determine categorical response rates.	Baseline and week 5
Secondary	AE, laboratory tests, physical and neurological examination, vital signs and 12-lead ECG to evaluate the safety of HSK16149 in 5 weeks post treatment.	Number and severity of AEs, clinical laboratory abnormalities, physical examinations, 12-lead electrocardiograms (ECGs), and vital signs.	From week 1 to week 5
Secondary	Compare the response rate between HSK16149 and placebo at week 13 (Proportion of subjects whose ADPS decreased by =30% and =50% from baseline ).	Ratio of Participants Responding to Treatment, as Measured by Average Daily Pain Score (ADPS) Reduction from Baseline. The ADPS is used to determine categorical response rates.	Baseline and week 13
Secondary	Compare the change from baseline in ADPS between HSK16149 and placebo at week 1 to 13.	The mean change in average daily pain score (ADPS) was measured using a 11-point numeric rating scale (NRS; 0 [no pain] to 10 [worst possible pain]. The rating averaged over a 7-day period and was based on entries in patients' daily pain diaries.	From week 1 to week 13
Secondary	Compare the change from baseline in Visual Analog Scale (VAS) between HSK16149 and placebo at week 13.	VAS, in which the participant rates pain on a 100 mm-long horizontal line, where 0 mm = no pain and 100 mm = worst possible pain.	Baseline and week 13
Secondary	Compare the change from baseline in Short-Form McGill Pain Questionnaire (SF-MPQ) between HSK16149 and placebo at week 13.	Participants rate their pain in three parts of the questionnaire, which are combined into a single pain intensity score: Part 1 - fifteen descriptors of pain intensity, on a scale of 0 (none) to 3 (severe); Part 2 - a visual analog scale (VAS), in which the participant rates pain on a 100 mm-long horizontal line, where 0 mm = no pain and 100 mm = worst possible pain; Part 3 - a Present Pain Intensity index in which the participant rates present pain intensity on a scale of 0 (no pain) to 5 (most intense pain)	Baseline and week 13
Secondary	Compare the Patient Global Impression of Change(PGIC) between HSK16149 and placebo at week 13.	Patient global impression of change (PGIC) on a 7-point categorical scale, where 1 = very much improved and 7 = very much worse.	Week 13
Secondary	Compare the change from baseline in Average Daily Sleep Interference score (ADSIS) between HSK16149 and placebo at week 13.	The sleep interference scores on a scale of 0-10, where 0 = pain did not interfere with sleep to 10 = pain completely interfered with sleep. The weekly ADSIS is based on participants daily sleep interference scores.	Baseline and week 13
Secondary	Compare the change from baseline in EuroQol-5-Domain-5-Level health questionnaire (EQ-5D-5L) between HSK16149 and placebo at week 13.	The change from baseline in total EuroQol-5-Domain-5-Level health questionnaire.	Baseline and week 13
Secondary	AE, laboratory tests, physical and neurological examination, vital signs and 12-lead ECG to evaluate the safety of HSK16149 during the trial.	Number and severity of AEs, clinical laboratory abnormalities, physical examinations, 12-lead electrocardiograms (ECGs), and vital signs.	From week 1 to week 14
Secondary	Pharmacokinetic (PK) characteristics of HSK16149 capsules in Chinese patients with diabetic peripheral neuropathic pain.	Pharmacokinetics will be determined by measuring serum concentration of HSK16149.	Week 1,week 5,week 11,week 13
