Outcome Measures
Primary Outcome Measures
- Compare the change from baseline in Average Daily Pain Score（ADPS） between HSK16149 and placebo at week 5. [Baseline and 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.
- Compare the change from baseline in Average Daily Pain Score （ADPS） between HSK16149 and placebo at week 13. [Baseline and 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.
Secondary Outcome Measures
- Compare the response rate between HSK16149 and placebo at week 5 (Proportion of subjects whose ADPS decreased by ≥30% and ≥50% from baseline ). [Baseline and week 5]
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.
- AE, laboratory tests, physical and neurological examination, vital signs and 12-lead ECG to evaluate the safety of HSK16149 in 5 weeks post treatment. [From week 1 to week 5]
Number and severity of AEs, clinical laboratory abnormalities, physical examinations, 12-lead electrocardiograms (ECGs), and vital signs.
- Compare the response rate between HSK16149 and placebo at week 13 (Proportion of subjects whose ADPS decreased by ≥30% and ≥50% from baseline ). [Baseline and week 13]
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.
- Compare the change from baseline in ADPS between HSK16149 and placebo at week 1 to 13. [From week 1 to 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.
- Compare the change from baseline in Visual Analog Scale （VAS） between HSK16149 and placebo at week 13. [Baseline and 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.
- Compare the change from baseline in Short-Form McGill Pain Questionnaire (SF-MPQ) between HSK16149 and placebo at week 13. [Baseline and 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)
- Compare the Patient Global Impression of Change（PGIC） between HSK16149 and placebo at week 13. [Week 13]
Patient global impression of change (PGIC) on a 7-point categorical scale, where 1 = very much improved and 7 = very much worse.
- Compare the change from baseline in Average Daily Sleep Interference score (ADSIS) between HSK16149 and placebo at week 13. [Baseline and 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.
- Compare the change from baseline in EuroQol-5-Domain-5-Level health questionnaire (EQ-5D-5L) between HSK16149 and placebo at week 13. [Baseline and week 13]
The change from baseline in total EuroQol-5-Domain-5-Level health questionnaire.
- AE, laboratory tests, physical and neurological examination, vital signs and 12-lead ECG to evaluate the safety of HSK16149 during the trial. [From week 1 to week 14]
Number and severity of AEs, clinical laboratory abnormalities, physical examinations, 12-lead electrocardiograms (ECGs), and vital signs.
- Pharmacokinetic (PK) characteristics of HSK16149 capsules in Chinese patients with diabetic peripheral neuropathic pain. [Week 1,week 5,week 11,week 13]
Pharmacokinetics will be determined by measuring serum concentration of HSK16149.
