简要总结
To evaluate the pharmacokinetic interaction of KL0011034 injection in combination with alfentanil hydrochloride injection.To evaluate the safety and tolerability of KL0011034 injection in combination with alfentanil hydrochloride injection.To evaluate the effect of alfentanil hydrochloride injection on the pharmacodynamics of KL0011034 injection.
详细描述
This study will be conducted among the participants with moderate-to-severe non-cancerous chronic pain, aiming to evaluate the drug-drug interactions between KL0011034 injection and alfentanil hydrochloride injection. The study consists of two parts:
Part 1 trial:
A single-center, randomized, open, parallel design is adopted to evaluate the safety, tolerability and pharmacodynamic characteristics of the combined use of KL0011034 injection and alfentanil hydrochloride injection.
It is planned to enroll 9 patients with moderate-to-severe non-cancerous chronic pain. All participants will be randomly assigned to one of the three dose groups in a 1:1:1 ratio, with 3 participants in each group. They will complete a single combined administration and undergo pharmacodynamic and safety evaluations.
Based on the results of Part 1 trial, KL0011034 injection will select the maximum dose with acceptable safety among the three doses for the second part of the study.
