• 1 other identifier: PY-HL-1186-II-01
• Study Type: interventional
• Target: 180
• Locations: 0 countries
• Sites: N/A

Brief Summary

This is a multi-center, randomized, double-blind, placebo-controlled study design evaluating the safety, efficacy, and PK parameter of HL-1186 tablet for diabetic peripheral neuropathic pain.

Conditions

Diabetic Peripheral Neuropathic Pain

Outcome Measures

Primary Outcomes (1)

• Change in average daily pain score (ADPS) from baseline after 12 weeks of administration

  Change from baseline in the weekly mean of the daily Numeric Pain Rating Scale (NPRS) score assessing the worst pain intensity in the last 24 hours. Pain intensity was recorded on 11-point NPRS, score range: 0 to 10, where 0= no pain and 10= worst imaginable pain.

  From baseline to the end of treatment at 12 weeks

Secondary Outcomes (1)

• Number of participants with treatment-related adverse events as assessed by CTCAE v5.0

  From first day of administration to the end of the last follow-up at Week 16

Eligibility Criteria

• Age: 18 Years - 75 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Aged between 18 and 75 years old (inclusive), regardless of gender.
• With Type 1 or Type 2 diabetes mellitus, with a diagnosis of DPNP for at least 6 months.
• Screening period: ADPS ranging from 4 to 9 points, and Visual Analog Scale (VAS) scores of 40mm - 90mm in two different days.
• The hypoglycemic regimen has been stable for at least 4 weeks before enrollment, and the glycated hemoglobin (HbA1c) during the screening period is ≤ 9%.
• Participants fully understand the purpose, characteristics, methods of the trial and possible adverse events, voluntarily participate in the trial and sign the informed consent form.

You may not qualify if:

• Participants with any pain other than DPNP, or with other diseases that the investigator deems may affect the evaluation of DPNP.
• Participants who are allergic to the active ingredients or excipients of HL-1186, HL-1186 placebo, or paracetamol tablets, or who have an allergic constitution, or have a history of allergies to ≥ 3 substances.
• Participants who have used drugs that may damage nerves (such as tumor chemotherapy drugs) after being diagnosed with DPNP.
• Participants who used any prohibited drugs within 2 weeks before screening (or within 5 half-lives after the last use of such prohibited drugs at the time of screening, whichever is longer).
• Participants who had acute diabetic complications within 6 months before screening, such as diabetic ketoacidosis, hyperglycemic hyperosmolar state, lactic acidosis, acute severe hypoglycemia, etc., or had lower limb amputation (except toe amputation) at the time of screening.
• Participants with neuropsychiatric system diseases that the investigator deems may affect the participant's evaluation of DPNP or scale evaluation, such as depression, anxiety, epilepsy, recurrent dizziness, memory and cognitive impairment, a history of suicide attempts or suicidal tendencies, etc.
• Participants with a history of malignant tumors within 2 years before screening (except for participants with basal cell carcinoma, squamous cell carcinoma, and stage 0 cervical carcinoma in situ that have been confirmed cured by the investigator).
• Participants with clinically significant and unstable diseases of the nervous system, mental system, ophthalmology, hepatobiliary system, respiratory system, hematological system, or cardiovascular system within 1 year before screening, and the investigator assesses that such diseases may endanger the participant's safety during the trial, restrict the participant from completing the study procedures, or affect the research purpose.
• Participants with positive human immunodeficiency virus antibody, positive syphilis serological test, positive hepatitis B virus surface antigen with hepatitis B virus DNA \> ULN, or positive hepatitis C virus antibody with hepatitis C virus RNA \> ULN.
• Participants with a history of alcoholism or drug abuse within 2 years before screening.
• Female participants who are pregnant, breastfeeding (within 1 year after delivery), or with a positive pregnancy test.
• Participants of childbearing potential who have plans to conceive, freeze or donate sperm/eggs from the time of signing the informed consent form until 6 months after the last dose, or who refuse to adopt effective contraceptive measures (complete abstinence, barrier methods, contraceptives, intrauterine devices, or having undergone sterilization surgery).
• Participants who have participated in other drug or medical device trials within 3 months before screening or are currently participating in other clinical trials.
• Participants deemed by the investigator to be unsuitable for participating in this study for any reason.
