Hengrui Medicine

Status and phase: Completed; Phase 1

Conditions: Advanced Solid Tumor

NCT04989829

SHR6390-I-113

Details and patient eligibility

About

This is a one-arm, fixed-sequence study to compare the pharmacokinetic profiles of SHR6390 in absence and presence of prior administration of proton pump inhibitor Omeprazole. The increased gastric pH achieved by the treatment with multiple doses of Omeprazole might affect the absorption process of SHR6390.

Enrollment: 20 patients

Sex: All

Ages: 18 to 45 years old

Volunteers: Accepts Healthy Volunteers
