Exclusion Criteria:

• Subjects who meet any of the following conditions cannot participate in this study:

  1. Subjects with a history of severe drug hypersensitivity or the hypersensitivity to IP and its ingredients or similar drugs
  2. Subjects with dysphagia
  3. Subjects confirmed with the following medical or surgical/procedural history:
• Primary malignant tumor other than ovarian cancer diagnosed or treated within 24 months prior to baseline (individuals with successfully treated cutaneous basal/squamous cell carcinoma are eligible for enrollment)
• Major surgery requiring general anesthesia or respiratory support within 4 weeks prior to baseline (2 weeks for video-assisted thoracoscopic surgery [VATS] or open-and-closed [ONC] surgery)
• Severe cardiovascular disease (e.g., myocardial infarction and unstable angina) that occurred within 24 weeks prior to baseline
• New York Heart Association Class 3 or 4 heart failure within 24 weeks prior to baseline
• Severe cerebrovascular disease observed within 24 weeks prior to baseline
• Pulmonary thrombosis or deep vein thrombosis within 24 weeks prior to baseline, or bronchial asthma, obstructive pulmonary disease, or other serious, life-threatening lung disease (e.g., acute respiratory distress syndrome and lung failure) considered ineligible for study participation
• Infections requiring treatment, such as systemic antibiotics and antivirals, within 2 weeks prior to baseline, or other uncontrolled ≥Grade 3 active infectious diseases
• Symptomatic interstitial lung disease
• Subjects who showed poor recovery from hematologic toxicity in the past chemotherapy (e.g., ≥grade 3 toxicity for ≥4 weeks)
• Bone marrow or stem cell transplantation with high-dose chemotherapy
• Total gastrectomy or total duodenectomy
• Individuals with a history of myelodysplastic syndrome (MDS) or pretreatment cytogenetic test results indicating a risk of MDS/acute myeloid leukemia (AML) 4) Subjects with the following concurrent conditions:
• Subjects with clinically significant symptoms or uncontrolled central nervous system or brain metastases (except when systemic corticosteroid administration was stopped at least 4 weeks prior to baseline and was stable for ≥4 weeks)
• Subjects who have confirmed clinically significant conditions in the electrocardiogram (ECG) according to the investigator's judgment
• Uncontrolled hypertension (systolic blood pressure >150 mmHg or diastolic blood pressure >90 mmHg)

• Subjects with neurological and psychiatric disorders severe enough to affect the study results according to the investigator's judgment 5) Subjects who have the following drug treatment history:
• Subjects who have received chemotherapy†, immunotherapy (including biologics), hormone therapy, or therapeutic/palliative radiotherapy‡ within 4 weeks prior to baseline
• Subjects who require continuous (≥4 weeks) treatment of systemic corticosteroids equivalent to prednisone >10 mg/day
• Subjects who were treated with antithrombotic drugs, including antiplatelet agents and anticoagulants, within 2 weeks from baseline or are expected to be treated with them during the study period (however, low molecular weight heparin [LMWH]) treatment is allowed)
• Subjects who require continuous administration of non-steroidal anti-inflammatory drugs (NSAIDs), which have high risk of bleeding 6) Pregnant or lactating women, or women of childbearing potential who do not intend to abstain or use appropriate contraceptive methods* during the study period and up to 3 months after IP administration *Appropriate contraception: 7) Subjects who have taken or undergone another IP or investigation device within 4 weeks prior to baseline 8) subjects who are judged by the investigator as ineligible for study participation
