Clinical Trial Summary

Lattice laser is a new medical cosmetic technology, which is a kind of noninvasive and invasive technology. Compared with traditional laser therapy, lattice laser has a wider range of clinical use, and can be used to treat skin problems such as acne marks, fine wrinkles, skin aging, chloasma, coffee spots, large pores and dullness. Dot-array laser has been widely used in the treatment of skin diseases and skin cosmetics because of its advantages of small trauma, rapid recovery, safety and effectiveness, and fewer complications. The facial skin is rich in nerve fibers and pain receptors are distributed punctuately. Most patients have pain and discomfort to varying degrees during laser treatment. The pain and discomfort associated with laser treatment of the face make anaesthesia an important assistant technique in laser skin cosmetology. At present, the commonly used anesthesia methods to relieve pain include: local cooling anesthesia, topical anesthesia, general anesthesia, gas inhalation anesthesia, intravenous anesthesia, iontophoresis anesthesia, etc. General anesthesia is usually associated with a risk of complications, residual areas of regional nerve block are often sensitive to pain, and acupuncture and drug injection can increase patient discomfort. Therefore, because of its simplicity and convenience of drug administration, topical anesthesia has a positive significance in facial lattice laser cosmetic treatment. The reference product lidocaine tetracaine cream (brand name: Pliaglis ®) has been marketed in the United States and the European Union for many years, and its therapeutic efficacy has been clinically recognized and has a good safety profile.Lidocaine tetracaine cream (R & D code: CU-30101) is manufactured by Cutia Therapeutics (Wuxi) Co., Ltd . A randomized, double-blind, multi-center clinical study is currently proposed to evaluate the efficacy and safety of CU-30101 in facial spot-array laser cosmetology in Chinese subjects with Pliaglis ® as a control.

Description:

On the one hand, MTZ can self-repair, stimulate collagen regeneration and improve skin texture; on the other hand, due to the small area of MTZ injury, the surrounding normal skin tissue can be rapidly repaired, reduce the risk of treatment and shorten the recovery time.

In accordance with the Chemical Drug Registration Category and Application Dossier Requirements (NMPA 2020 No. 44), lidocaine tetracaine cream (R & D code: CU-30101) manufactured by Corde Biopharmaceuticals (Wuxi) Co., Ltd. is registered as a chemical class 3. A randomized, double-blind, multi-center clinical study is currently proposed to evaluate the efficacy and safety of CU-30101 in facial spot-array laser cosmetology in Chinese subjects with Pliaglis ® as a control.
