• Any prior treatment-related (i.e., chemotherapy, immunotherapy, radiotherapy) clinically significant toxicities that have not resolved to Grade ≤ 1 or prior treatment-related toxicities that are clinically unstable and clinically significant at Study Entry, Day -2 to Cycle 1 Day 1.
• Major surgery within 30 days before the first dose of study drug treatment in Cycle 1 on Day 1 (port placement for venous access is not considered major surgery).
• Venous thrombosis or pulmonary embolism within the last 3 months prior to the screening.
• Ongoing or active infection requiring intravenous treatment with anti-infective therapy or systemic therapy and/or any identified active COVID-19 infection.

Más betegség

• Significant cardiovascular impairment.
• Known active and clinically significant bacterial, fungal, or viral infection.
• Uncontrolled hypertension defined as systolic blood pressure ≥ 160mmHg and/or diastolic blood pressure ≥ 100mmHg, despite optimal medical management.
• Any other major illness that, in the Investigator's judgment, will substantially increase the risk associated with the subject's participation in this study.
