Luye Pharma has completed patient enrolment in a Phase II clinical trial of its LY03014 drug to treat acute postoperative pain and breakthrough cancer pain in China.

The placebo and positive parallel-controlled, multicentre, double-blind, randomised study is intended to assess the preliminary safety and efficacy of the investigational drug as an analgesic.

Patients with moderate-to-severe pain after abdominal surgery are enrolled in the study.

Improvements in pain threshold and tolerance were observed in subjects administered with a single intravenous infusion of LY03014 in a Phase I study. It also showed a good overall safety profile.

LY03014 is a small-molecule G protein-biased mu-opioid receptor (MOR) agonist.

It completely separates the β-arrestin-2, G protein pathways and reduces the risk of opioid-induced respiratory depression (OIRD), a common risk factor in patients leading to death.
