About

This is a single arm，open-label, multicentric, phase II study to evaluate the efficacy and safety of KC1036 in patients with advanced recurrent or metastatic thymoma or thymic carcinoma.

Full description

Thymus tumor is a relatively rare type of thoracic tumor. Patients with thymus tumor who have failed to receive first-line chemotherapy lack of effective therapeutic drugs and clinical need is urgent. Previous phase I study showed that KC1036 has a good therapeutic effect in patients with advanced thymic tumors, and KC1036 is safe and well tolerated in patients with advanced tumors. This study further explored the efficacy and safety of KC1036 in patients with advanced thymic tumors.

Patients will receive continuous treatment with oral KC1036 60 mg once daily. Each cycle will be considered as 21 days of treatment; safety was assessed every 21 days. Tumor assessement will be done every two cycles. Treatment should be administered until documented disease progression, unacceptable toxicity, or patient refusal.
