crisugabalin (HSK16149) / Haisco - LARVOL DELTA

Crisugabalin, a ligand for the α2δ subunit of voltage-gated calcium channels, exhibits no obvious abuse potential in rodents. (PubMed, Pharmacol Biochem Behav) - "Secondly, a rat drug discrimination study was employed to determine the pharmacological similarity between crisugabalin and the training drug midazolam. In the rat spontaneous withdrawal study, crisugabalin demonstrated a very low level of physical dependence. These findings suggest that crisugabalin has minimal to no potential for abuse, thereby establishing itself as a safer option relative to pregabalin and mirogabalin."

Efficacy and Safety of Crisugabalin (HSK16149) in Adults with Postherpetic Neuralgia: A Phase 3 Randomized Clinical Trial. (PubMed, JAMA Dermatol) - P3 | "Participants included adults with postherpetic neuralgia with an average daily pain score (ADPS) of at least 4 on the 11-point Numeric Pain Rating Scale over the preceding week, with the exclusion of patients with pain not controlled by prior therapy with pregabalin (≥300 mg/d) or gabapentin (≥1200 mg/d). Crisugabalin, 40 mg/d, or crisugabalin, 80 mg/d, was well tolerated and demonstrated a statistically significant improvement in ADPS over placebo. ClinicalTrials.gov Identifier: NCT05140863."
