Summary

The primary objective of this study is to evaluate the pathological response rate of neoadjuvant therapy with paclitaxel polymersomes for injection combined with carboplatin and adebrelimab in patients with resectable mucosal melanoma.Subjects will receive the combination therapy of paclitaxel polymersomes for injection, carboplatin and adebrelimab prior to surgery, with a treatment cycle of 3 weeks and a total of 3 cycles.After completing 3 cycles of treatment, subjects will undergo curative surgery. Pathologists will evaluate the surgically resected specimens to determine the status of pathological response, and immunohistochemical assays will be performed to assess the intensity of immune activation within the tumor microenvironment.

Conditions

• Resectable Mucosal Melanoma

Interventions

Type	Name	Description
DRUG	Paclitaxel Polymersomes Combined with Carboplatin and Adebelimab	Chemotherapeutic agents are administered on Day 1 of each cycle: paclitaxel polymersomes for injection is given first, followed by carboplatin.Adebelimab injection is administered on Day 2 of each cycle.Patients will receive a maximum of 3 cycles of neoadjuvant chemotherapy combined with immunotherapy before surgery.Patients who are evaluated as resectable 3 weeks after the last cycle of chemotherapy will undergo radical surgery.
PROCEDURE	Radical Surgery	Chemotherapeutic agents are administered on Day 1 of each cycle: paclitaxel polymersomes for injection is given first, followed by carboplatin.Adebelimab injection is administered on Day 2 of each cycle.Patients will receive a maximum of 3 cycles of neoadjuvant chemotherapy combined with immunotherapy before surgery.Patients who are evaluated as resectable 3 weeks after the last cycle of chemotherapy will undergo radical surgery.
