Nab-PCE vs PC for MM After Failure of Anti-PD-1

This is a randomized controlled clinical trial of nab-paclitaxel + carboplatin

* Endostatin for advanced melanoma after failure of PD-1 therapy. The aim was to evaluate the efficacy and safety of nab-paclitaxel+carboplatin
* endostatin versus combination of paclitaxel and carboplatin in patients with advanced melanoma after failure of PD-1 therapy.

The enrollment time is expected to be 1.5 year and the observation time is 2 years. The regimen were performed on a 28-day/21-day cycle respectively. Subjects who met the entry criteria were treated in a 2:1 group according to a randomized list: the treatment group was treated with nab-paclitaxel + carboplatin + endostatin regimen, and the control group was treated with paclitaxel + carboplatin. In this trial, the efficacy is evaluated every 8 weeks until disease progression or unacceptable toxicity,or until the investigator deemed that the patient's condition was unacceptable for further treatment. The follow-up period was 24 months after the end of treatment (follow-up patient survival information and new anti-tumor treatment). The planning enrolled sample size for nab-paclitaxel + carboplatin + endostatin group and paclitaxel-carboplatin group were 90 patients and 45 patients, respectively.
