A Pilot Study of Dociparstat Sodium (ODSH) in Acute Myeloid Leukemia — PGX-AML  

Acute Myeloid Leukemia Clinical Trial

Official title: A Pilot Study to Evaluate the Safety and Preliminary Evidence of an Effect of ODSH (2 O, 3-O Desulfated Heparin) in Accelerating Platelet Recovery in Patients Receiving Induction or Consolidation Therapy for Acute Myeloid Leukemia

Status Completed

Clinical Trial Summary

This was an open-label pilot study that evaluated the safety and preliminary evidence of a therapeutic effect of dociparstat in conjunction with standard induction and consolidation therapy for acute myeloid leukemia (AML).

Clinical Trial Description

The primary objectives of this study were the following:

1. To evaluate the safety and tolerability of dociparstat in patients with acute myeloid leukemia (AML) receiving cytarabine and idarubicin induction or cytarabine consolidation chemotherapy.

2. To determine whether there is preliminary evidence of an effect of dociparstat on time to transfusion-independent platelet recovery in AML patients receiving cytarabine and idarubicin induction or cytarabine consolidation chemotherapy.

The secondary objectives of this study were the following:

1. To determine whether there is preliminary evidence of an effect of dociparstat on remission rate following cytarabine and idarubicin induction in AML patients.

2. To determine whether there is preliminary evidence of an effect of dociparstat on improving platelet nadir counts in AML patients receiving cytarabine and idarubicin induction or cytarabine consolidation chemotherapy.

3. To determine whether there is preliminary evidence of an effect of dociparstat on decreasing the number of platelet transfusions in AML patients receiving cytarabine and idarubicin induction or cytarabine consolidation chemotherapy.

4. To determine whether there is preliminary evidence of an effect of dociparstat on reducing overall side effects of chemotherapy in AML patients receiving cytarabine and idarubicin induction or cytarabine consolidation chemotherapy.

This study enrolled patients with newly diagnosed, previously untreated AML; subjects with acute promyelocytic leukemia and acute megakaryoblastic leukemia subtypes were excluded.

All patients were to receive standard induction chemotherapy with cytarabine 100 mg/m2/day by continuous intravenous (IV) infusion over 24 hours daily for 7 days (Days 1-7) plus idarubicin 12 mg/m2/day by IV injection daily for 3 days (Days 1-3). For consolidation, patients younger than 60 were to receive cytarabine at a dose of 3 grams/m2 over 3 hours, every 12 hours on days 1, 3, and 5.

Induction cycle: dociparstat 4 mg/kg IV bolus Day 1, 30 minutes after completion of administration of the first dose of idarubicin, then dociparstat 0.25 mg/kg/hour for 24 hours daily by continuous IV infusion Days 1-7.

Consolidation cycle: dociparstat mg/kg IV bolus Day 1 administered 30 minutes after completion of infusion of the first dose of cytarabine then dociparstat 0.25 mg/kg/hour for 24 hours daily by continuous IV infusion Days 1-5

In total, there were 7 days in the induction cycle and 5 days in the consolidation cycles. ;
