• Unsuitability for oral administration of the investigational drug, as judged by the investigator, including:
• Clinically significant or uncontrolled congenital or acquired gastrointestinal diseases;
• Diseases that may affect drug administration, gastric entry, or absorption (e.g., intestinal obstruction, Crohn's disease, ulcerative colitis).
