Enrolling ahead of pace

Detailed Summary

Researchers are looking for new ways to treat people with a type of blood cancer called precursor B-cell Acute Lymphoblastic Leukemia (B-ALL) that is relapsed- the cancer has come back after treatment, or refractory - the current treatment has stopped working to slow or stop cancer growth. This study will have two parts. In the first part (dose escalation phase) the goal is to learn about the safety of a study treatment, MK-1045, and to find the best dose level of MK-1045 that is tolerated and may work to treat B-ALL. In the second part (Phase II) researchers want to learn how well MK-1045 works to treat B-ALL.

Arms & Interventions

MK-1045: Dose Escalation Phase- Adult Cohortexperimental

Adults in the dose escalation phase will receive a target dose level of MK-1045 from 600 μg to 120,000 μg, administered by intravenous (IV) infusion. MK-1045 will be administered once per week, in treatment cycles defined as 4 weeks of MK-1045 treatment.

Drug: MK-1045
MK-1045 : Dose Escalation Phase- Pediatric Cohortexperimental

Pediatric participants will receive a target dose level of MK-1045 from 320 μg to 60000 μg, with dosing further based upon weight. MK-1045 will be administered by IV infusion once per week, in treatment cycles defined as 4 weeks of MK-1045 treatment.

Drug: MK-1045

Interventions

MK-1045drug

MK-1045 is administered by IV infusion once a week (QW), 4 weeks per treatment cycle, starting with 2 cycles of induction treatment. After a 2-week treatment-free interval, responders to induction treatment receive 3 cycles of consolidation therapy, and up to 7 cycles of maintenance treatment or until intolerable toxicity, disease progression, withdrawal of informed consent, loss to follow-up, receipt of other antitumor therapy, or death, whichever occurs first. Each 4 week treatment cycle is followed by a 2-week treatment-free interval.
