Compare the change from baseline in Average Daily Pain Score (ADPS) between HRS-2129 and placebo at Week 4.
Timeframe: Baseline and Week 4.
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 response rate between HRS-2129 and placebo at Week 4 (Proportion of subjects whose ADPS decreased by ≥ 30% and ≥ 50% from baseline).
Timeframe: Baseline and Week 4.
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 HRS-2129 and placebo at Week 1 to 4.
Timeframe: From Week 1 to Week 4.
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 HRS-2129 and placebo at Week 4.
Timeframe: Baseline and Week 4.
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 HRS-2129 and placebo at Week 4.
Timeframe: Baseline and Week 4.
Participants rate their pain in three parts of the questionnaire, which are combined into a single pain intensity score: Part 1 - 11 descriptors of pain intensity, and 4 descriptors of emotions, 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 HRS-2129 and placebo at Week 4.
Timeframe: At Week 4.
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 HRS-2129 and placebo at Week 4.
Timeframe: Baseline and Week 4.
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.
Number and severity of serious adverse events (SAEs).
Timeframe: From Week 1 to Week 6.
To evaluate the safety of HRS-2129 during the trial.
Number and severity of adverse events (AEs).
Timeframe: From Week 1 to Week 6.
To evaluate the safety of HRS-2129 during the trial.
Population Pharmacokinetics (PopPK) characteristics of HRS-2129 in Chinese patients with diabetic peripheral neuropathic pain - Serum concentration of HRS-2129.
Timeframe: From Day 0 to Day 30.
Population Pharmacokinetics (PopPK) will be determined by measuring serum concentration of HRS-2129.
