Подробное описание

This study is a prospective, multicenter, single arm, open label study aimed at evaluating the efficacy and safety of the combination of Carilizumab, Apatinib Mesylate, and first-line radiotherapy for advanced mucosal melanoma. The study will use the 6-month progression free survival rate (PFS6) as the primary efficacy indicator and plan to enroll approximately 30 non-surgical first-line treatment subjects with mucosal melanoma. After being fully informed and signing informed consent forms, the subjects will be screened and qualified to receive the following treatments: Induction phase (2 cycles): 200mg of Carilizumab, intravenous infusion, administered once every 2 weeks, with a 4-week cycle; Apatinib mesylate 500mg, oral, once daily, adjusted according to patient tolerance, with a 4-week cycle; Completed 2 cycles in total. ·Synchronous radiotherapy stage: 200mg of Carilizumab is administered intravenously once every 2 weeks, with a 4-week cycle; Apatinib mesylate 500mg, oral, once daily, adjusted according to patient tolerance, with a 4-week cycle; The radiation therapy plan evaluated by the researchers: the radiation dose and radiation field are determined by the researchers, with an overall principle of 18-25Gy/3-6f, or equivalent BED. Three dimensional conformal radiotherapy (3D-CRT) or intensity-modulated conformal radiotherapy (IMRT) techniques are used for radiotherapy. Radiotherapy should be scheduled before the use of PD-1 antibody Carilizumab, and intravenous infusion of Carilizumab should be administered within 48 hours after the end of radiotherapy. If there are multiple lesions that can be treated with radiotherapy, after evaluation by the research team, sequential radiotherapy for multiple lesions is allowed based on the lesion location and the tolerance of surrounding normal organs. ·Maintenance phase: Carilizumab 200mg, intravenous infusion, administered once every 2 weeks, with a 4-week cycle; Apatinib mesylate 500mg, oral, once daily, adjusted according to patient tolerance, with a 4-week cycle; Until tumor progression, intolerance, initiation of other anti-tumor treatments, loss to follow-up, or death. The cumulative maximum shall not exceed 2 years. After the completion of treatment, subjects will continue to undergo post-treatment safety and survival follow-up. For subjects who have completed treatment due to non disease progression/death reasons, tumor progression follow-up will also be conducted after the completion of treatment. Safety visit: After the subjects are enrolled in the study, safety visits will be conducted at each treatment cycle D1 and at the end of treatment visit. Imaging assessment: All lesions were recorded and evaluated according to RECIST 1.1. The window period allowed for imaging examinations is ± 7 days unless otherwise specified. During the research period, unplanned imaging examinations may be performed when tumor progression is suspected. The assessment of tumor baseline within 4 weeks before enrollment, CT/MRI scan results obtained before signing informed consent can be used for screening tumor assessment as long as they meet the requirements; Suspected brain metastases require enhanced MRI/CT of the brain to rule out brain metastases. When there is a clear or clinical suspicion of bone metastasis, bone scan examination should be performed to exclude bone metastasis. Within 12 months after the first administration, imaging examinations should be conducted every 2 cycles (± 7 days). After 12 months, imaging examinations should be conducted every 3 cycles (± 7 days). If there is suspicion of metastasis to other areas, additional imaging examinations for that area should be performed. After terminating the study treatment, subjects who did not show imaging progression continued to undergo imaging evaluation at the frequency of the treatment period until imaging progression, acceptance of other anti-tumor treatments, withdrawal of informed consent, loss to follow-up, or death occurred. Survival follow-up: After the completion or withdrawal of the study, survival and post study information will be collected through telephone follow-up every 3 months until death, loss to follow-up, withdrawal of informed consent, observation for 1 year, or termination of the study by the researcher.
