- −Monoclonal antibodies, antibody-drug conjugates, radioimmunoconjugates, or similar investigational therapies within 6 weeks prior to the initiation of study drug or participants who have not recovered (i.e., ≤ Grade 1 or to baselineBaselineYour starting measurements, taken before treatment begins.Read more →) from AEs due to agents administered more than 4 weeks earlier. Note: Participants with ≤ Grade 2 neuropathy or ≤ Grade 2 alopecia are an exception to this criterion and may qualify for the study.
- −Clinically significant cardiovascular/vascular disease, gastrointestinal disorders, inflammatory processes, pulmonary compromises
- −Active viral, bacterial, or systemic fungal infection requiring parenteral treatment within 7 days prior to the initiation of study drug.

- −Pregnant, likely to become pregnant, or lactating women (where pregnancy is defined as the state of a female after conception and until the termination of gestation).
- −Major surgery or traumatic injury within 8 weeks before first dose of study drug.
- −Unhealed wounds from surgery or injury.
