Trial outcomes
Primary outcomes
Phase I: Dose-limiting toxicity (DLT) observation

Secondary outcomes
Phase II: Overall response rate (PR + CR)(at least 1 cycle)
Overall response rate (PR + CR) after at least 1 cycle of combination use in BLEX 404 + Docetaxel monotherapy.
Phase II: Incidence of grade 3/4 hematological toxicity
Rate of grade 3/4 hematological toxicity of each cycle.
