Volasertib and Vincristine Sulfate Liposome in Treating Patients With Relapsed or Refractory Acute Lymphoblastic Leukemia

Recurrent Adult Acute Lymphoblastic Leukemia Clinical Trial

Official title: A Phase I Clinical Trial Evaluating the Combination of Volasertib (BI-6727) With Vincristine Sulfate Liposomal Injections (VSLI) in Adult Patients With Relapsed/Refractory Acute Lymphoblastic Leukemia

Status Withdrawn

Clinical Trial 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.

Clinical Trial 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. ;
