Más betegség

• Absorption disorder syndrome or other diseases affecting oral drug absorption.
• Pulmonary systolic pressure (PSP) of echocardiography is more than 50 mmHg, or there is clinical symptom related to pulmonary hypertension.

• History of another primary malignancies.
• Active symptomatic infection.
• Known to be allergic to study drug ingredients or their analogues.
• Suffer from any condition or illness that, in the opinion of the Investigator or the medical monitor, would compromise patient safety or interfere with the evaluation of the safety of the research drug.

Laborértékek

• Have any history of heart or vascular disease, such as hypertension (systolic blood pressure (HBP) > 140mmHg and/or diastolic blood pressure > 90mmHg), or take medications that are known to cause QT interval prolongation. The patients with well controlled HBP can be included.
