Phase II Study for Combination of Camrelizumab and Apatinib in the Second-line Treatment of Recurrent or Metastatic Adrenocortical Carcinoma

Adrenocortical carcinoma (ACC) is a rare aggressive malignant tumor. According to the literature, the 5-year survival rate of ACC is 12%-47%. For patients with advanced ACC, mitotane alone or combined with traditional chemotherapy was the first-line standard treatment, but its progression-free survival was only about 1 year. However, for patients who fail the first-line treatment, there is a lack of effective treatment. For ACC patients who had failed first-line chemotherapy, a phase II clinical trial found that the objective response rate and the disease control rate of PD-1 inhibitor Keytruda were 14% and 64% respectively, and no grade 3 or 4 adverse events were observed. Anti-tumor angiogenic drugs combined with PD-1 inhibitors have shown impressive clinical data in many solid tumors. This study is aimed to evaluate the efficacy and safety of PD-1 inhibitor camrelizumab combined with apatinib in patients with recurrent or metastatic ACC after standard treatment failure, and to seek new treatment for this population.
