Brief Summary

The main purpose of this investigational research study is to determine how safe and tolerable the study drug volasertib is in combination with liposomal vincristine (Marqibo; an FDA-approved drug) in patients with relapsed/refractory acute lymphoblastic leukemia. While VSLI demonstrated an overall response rate of 35% in Acute Lymphoblastic Leukemia (ALL) patients that had failed to respond to or relapsed after chemotherapy, combining it with other agents may increase clinical benefit.

Volasertib inhibits proteins involved in the cell cycle that are increased in ALL. When volasertib inhibits these proteins ALL cells die. In the laboratory, volasertib has been shown to increase activity of vincristine against ALL cells. Therefore, we think the combination of volasertib and VSLI will be more effective against your leukemia than either drug used alone. This study will try to find out what effects, good and/or bad, this drug combination has on the patient and their cancer, and to find a dose that may be used in future studies.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of the combination of volasertib and vincristine sulfate liposomal injection (VSLI) in relapsed/refractory (RR) acute lymphoblastic leukemia (ALL).

SECONDARY OBJECTIVES:

I. To determine the toxicity profile of volasertib and VSLI, rate of complete remission (with or without complete hematologic recovery; complete response \[CR\]/CR with incomplete hematologic recovery \[CRi\]), duration of remission (DOR), rate of minimal residual disease (MRD)-negativity, progression free survival (PFS), overall survival (OS), 30-day mortality rate.

TERTIARY OBJECTIVES:

I. To determine if volasertib and polo-like kinase (plk)-inhibition down-regulates the mammalian target of rapamycin (mTOR) pathway.

II. Whether plk and mTOR inhibition correlates with clinical response to treatment. III. to determine if volasertib acts synergistically to potentiate the bioavailability and distribution of VSLI.

OUTLINE: This is a dose-escalation study of volasertib.

Patients receive volasertib intravenously (IV) over 1 hour on day 1 and vincristine sulfate liposome IV over 1 hour on days 1, 8, 15, and 22. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression, development of an inter-current illness that prevents further administration of treatment, unacceptable toxicity, patient decides to withdraw or treating investigator determines that the patient should be taken off treatment for any reason.

After completion of study, patients are followed up every 28 days for up to 1 year.

    • Has not undergone a hysterectomy or bilateral oophorectomy
    • Has had menses at any time in the preceding 12 consecutive months (and therefore has not been naturally postmenopausal for > 12 months)

• Patients must have the ability to understand and the willingness to sign a written informed consent prior to registration on study

Exclusion Criteria

• Patients who have had chemotherapy, immunotherapy, or radiotherapy within 2 weeks prior to entering the study or those who have not recovered from adverse events (=< grade 1 or patient's baseline) due to agents administered more than 2 weeks earlier are not eligible

• Patients may not be receiving any other investigational agents within 7 days of registration

• Patients may not be receiving any medications that are known to prolong QT interval unless reviewed and approved by the principal investigator (PI)

• Subject may not have had hematopoietic stem cell transplant (HSCT) meeting any of the following:

  • Is within 2 months of transplant from cycle 1 day 1 (C1D1)
  • Has clinically significant graft-versus-host disease requiring treatment
  • Has >= grade 2 persistent non-hematological toxicity related to the transplant

• Patients who have an uncontrolled intercurrent illness including, but not limited to any of the following, are not eligible:

  • Ongoing or active infection requiring systemic treatment

  • Symptomatic congestive heart failure (>= class 3)

  • Unstable angina pectoris
