Summary
Brief summary (as posted)
This study is an investigator-initiated clinical study to evaluate the safety and tolerability of melphalan hydrochloride for injection in patients with relapsed or relapsed refractory multiple myeloma. Using the "3 + 3" dose escalation principle, 3-6 subjects per dose were enrolled, depending on the dose limiting toxicity (DLT) observed in the first cycle of chemotherapy for each subject. After completing the 21-day assessment of the first cycle of chemotherapy, if there was no DLT, the study started for the next dose group.
