What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 28 participants in total. It began in 2025-03-15 with a primary completion date of 2026-12-31.

Brief Summary

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. The efficacy of mitotane monotherapy is approximately 10% to 30%. FIRM-ACT trial reported an objective response rate (ORR) of 23.2% for etoposide, doxorubicin, cisplatin, and mitotane (EDP-M) chemotherapy regimen. Our phase II study found that PD-1 inhibitor camrelizumab and apatinib showed impressive clinical data in the second-line treatment of relapsed and metastatic ACC patients. The aim of this study is to evaluate the efficacy and safety of PD-1 inhibitor camrelizumab combined with apatinib and mitotane in advanced ACC, and to explore a new treatment strategy for patients with advanced ACC.
