Inclusion Criteria:

• Age ≥18 years.
• Had Ph- ALL or lymphoblastic lymphoma and was in second relapse, or had failed 2 treatment lines of anti-leukemia chemotherapy.
• Had histologically or cytologically proven ALL and ≥ 10% bone marrow blasts. If < 10% bone marrow blasts, subject must have had histologically or cytologically proven ALL and evaluable extramedullary disease. Sponsor approval was obtained prior to enrolling subjects who had < 10% bone marrow blasts with evaluable extramedullary disease.
• Had achieved a CR to at least 1 prior anti-leukemia therapy as defined by a leukemia-free interval of ≥ 90 days.
• For subjects with a prior history of stem cell transplantation, had ≤ Grade 1 active skin graft-versus-host disease (GVHD). No active gastrointestinal or liver graft-versus-host disease.
• Had an Eastern Cooperative Oncology Group (ECOG) performance status 0 to 3.
• Had normal renal and liver function as defined below within 14 days, inclusive, prior to first dose of VSLI, unless the abnormality was considered attributable to leukemia:
• Total bilirubin ≤ 2.0 × institutional upper limit of normal, unless the subject had a known diagnosis of Gilbert's disease. If a subject had Gilbert's disease, he/she could have participated in this study, however must have been monitored closely during the study.
• Aspartate transaminase (AST) or alanine transaminase (ALT) ≤ 3 × institutional upper limit of normal.
• Serum creatinine ≤ 2.0 g/dL or calculated estimated creatinine clearance ≥ 50 mL/minute/1.73 m2 based on Cockcroft and Gault formula, unless renal dysfunction was considered due to hematologic malignancy.
• Had never received prior VSLI treatment.
• For women of childbearing potential, had a negative serum or urine pregnancy test within 14 days prior to enrollment.
• If female, the subject was postmenopausal, surgically sterilized, or willing to use acceptable methods of birth control (e.g., hormonal contraceptive, intra-uterine device, diaphragm with spermicide, and condom with spermicide or abstinence) from the Screening visit through 30 days after the last dose of VSLI.
• If male, the subject agreed to use an acceptable barrier method for contraception from the Screening visit through 30 days after the last dose of VSLI.
• Before enrollment, the subject was capable of understanding and complying with parameters as outlined in the protocol and able to sign a written informed consent according to ICH/GCP and national/local regulations.

Exclusion Criteria:

• Had Burkitt's lymphoma or Burkitt's leukemia.
• Had a history of Philadelphia chromosome-positive (Ph+) ALL and/or BCR/ABL rearrangements documented by fluorescent in situ hybridization or polymerase chain reaction.
• Had a history of Philadelphia chromosome-positive (Ph+) ALL and/or BCR/ABL rearrangements documented by fluorescent in situ hybridization or polymerase chain reaction.
• Had active CNS disease. History of treated CNS disease was allowable. The CNS disease must have resolved in order for the subject to be eligible.
• Was eligible for stem cell transplantation. This implied that a suitable donor was readily available, the subject was willing to undergo stem cell transplantation, and the Investigator believed this was a better treatment option than VSLI. This was at the Investigator's discretion.
• Was treated with any investigational agents or chemotherapy agents in the last 21 days before the first dose of VSLI, unless full recovery from side effects had occurred or the subject had rapidly progressing disease judged to be life threatening by the Investigator.
• Was receiving any other standard or investigational treatment for the subject's leukemia.
• Intrathecal chemotherapy for CNS prophylaxis was allowable.
• The use of hydroxyurea (Hydrea®) to control leukocytosis was allowable but must have been tapered off by Day 14 of Course 1. From Day 15 of Course 1 on through the end of study participation, hydroxyurea (Hydrea®) was not allowed.
• Systemic corticosteroids must have been tapered off, preferably before the start of study treatment, but no later than by Day 5 of Course 1. From Day 6 of Course 1 on through the end of study participation, systemic corticosteroids were not allowed.
• Had persistent chronic clinically significant toxicities from prior chemotherapy ≥ Grade 2 (National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE] version 3.0).
• Had persistent ≥ Grade 2 active neuropathy (NCI CTCAE v3.0).
• Had a history of persistent ≥ Grade 2 active neurologic disorders unrelated to chemotherapy (including demyelinating form of Charcot-Marie-Tooth syndrome, acquired demyelinating disorders, or other demyelinating condition).
• Had a history of allergic reactions or sensitivity attributed to compounds of similar chemical or biologic composition to vincristine or components of study drug.
• Was female who was pregnant or breast-feeding.
• Had active serious infection not controlled by oral or intravenous antibiotics or antifungals.
• Had human immunodeficiency virus positive status.
• Had any medical condition which in the opinion of the investigator placed the subject at an unacceptably high risk for toxicities.
• Had any condition or circumstance which in the opinion of the investigator would significantly interfere with the subject's protocol compliance and put the subject at increased risk.
