Morphologic complete remission (CR) was evaluated by International Working Group (IWG) criteria and defined as absolute neutrophil count (ANC) \>1000/microliter; platelet count \>100,000, \<5% blasts in bone marrow aspirate, no blasts with Auer rods, and no evidence of extramedullary disease.
A primary endpoint of this study was evidence of an effect of dociparstat on transfusion independent platelet recovery time. The time (days) to transfusion-independent platelet recovery will be defined as the number of days from the first day of chemotherapy until the first of 5 consecutive days with platelet counts values ≥ 20,000/μL and ≥ 50,000/μL without a platelet transfusion.

Dociparstat is being studied for the treatment of acute myeloid leukemia, a cancer of the blood and bone marrow. It has been evaluated in clinical trials in combination with standard induction therapy for newly diagnosed acute myeloid leukemia, and separately in a pilot study in patients with the disease.
Dociparstat is a small molecule that belongs to the -stat enzyme class. It is designed to act on enzyme activity, which is the mechanism described for this agent. It is being investigated in acute myeloid leukemia, though its specific role in the treatment regimen continues to be studied in clinical trials.
Dociparstat is being developed by Jazz Pharmaceuticals plc, which trades under the ticker JAZZ. The company holds the development program for this small molecule agent in acute myeloid leukemia.
Dociparstat is in Phase 2 development. It is an investigational agent and has not been approved by the FDA. Two clinical trials have been completed, including a Phase 2 study and a Phase 1 pilot study, and no trials are currently active.
Dociparstat has been studied in two completed trials. NCT02873338 was a Phase 2 trial of dociparstat sodium combined with standard induction therapy in newly diagnosed acute myeloid leukemia, enrolling 75 patients. NCT02056782 was a Phase 1 pilot study in acute myeloid leukemia, enrolling 12 patients.
Yes, Dociparstat sodium is another name for Dociparstat. The two names refer to the same investigational small molecule, which has also appeared in trial records under the codes CX-01 and ODSH. All of these names refer to the same agent being studied in acute myeloid leukemia.
