Philadelphia chromosome-negative (Ph–) acute lymphoblastic leukemia (ALL) in second or greater relapse or has progressed following ≥2 anti-leukemia therapies.

For IV use only; fatal if given by other routes. Discontinue and treat if extravasation is suspected. Preexisting neuromuscular disorders. Monitor for symptoms of neuropathy before and during therapy; if occurs or worsens, delay, reduce or discontinue dose. Monitor CBCs prior to each dose; if Grade 3 or 4 myelosuppression develops, consider dose delay or reduction. Monitor for tumor lysis syndrome; manage if occurs.
