9. Recovery from all the other reversible AEs from prior antineoplastic therapy prior to the first administration of the trail drug (i.e. ≤ grade 1, according to CTCAE v5.0), excluding alopecia (any grade) and ≤ grade 2 peripheral sensory neuropathy or lymphocytopenia. Subjects who develop other abnormalities without clinically significant or investigator-judged risk-free toxicity will be enrolled only after discussion and approval by the sponsor and investigator.

Exclusion Criteria
