Patients who have ever received telatinib treatment 17. Patients who have received any investigational agent within ≤ 4 weeks immediately prior to C1D1 or plan to receive other investigational agent during the course of this study 18. Patients who have known or suspected allergies to telatinib mesylate tablet, its recipients, and drugs of the similar class 19. Women who are breast-feeding, or have positive results of serum pregnancy test within ≤ 7 days immediately prior to C1D1, or sexually active males and pre/perimenopausal women who do not agree to use an accepted and effective method of contraception or to abstain from sexual intercourse for the duration of their participation in the study and for 3 months after discontinuation of therapy 20.
