Description:
This study is being done to evaluate the safety, tolerability and antitumor activity of oral
CG-806 for the treatment of patients with Acute Myeloid Leukemia (except APML), secondary
AML, or therapy-related AML whose disease has relapsed, is refractory or who are ineligible
for or intolerant of intensive chemotherapy or transplantation.

Purpose
This study is being done to evaluate the safety, tolerability and antitumor activity of oral
CG-806 for the treatment of patients with Acute Myeloid Leukemia (except APML), secondary
AML, or therapy-related AML whose disease has relapsed, is refractory or who are ineligible
for or intolerant of intensive chemotherapy or transplantation.
Detailed Description
This is a multicenter, open-label, Phase 1 a/b dose escalation study of safety,
pharmacodynamics, and pharmacokinetics of CG-806 in ascending cohorts (3+3 design) to
determine the MTD or recommended dose in patients with relapsed or refractory Acute Myeloid
Leukemia (except APML), secondary AML, or therapy-related AML whose disease has relapsed, is
refractory or who are ineligible for or intolerant of intensive chemotherapy or
transplantation. This is to be followed by a cohort expansion phase.
Trial Arms
Name | Type | Description | Interventions |
---|
Dose Escalation and Expansion | Experimental | Dose Escalation and Expansion; CG-806 will be given orally in ascending doses in patients with relapsed or refractory AML (escalation cohort), until the maximum tolerated dose or candidate recommended Phase 2 dose is reached. Followed up by up to 50 patients enrolled in the expansion cohort at the recommended dose. | |

- Adequate renal, liver and cardiac functions
Key Exclusion Criteria:
- Patients with GVHD requiring systemic immunosuppressive therapy

treatment administration
Maximum Eligible Age: | N/A |
Minimum Eligible Age: | 18 Years |
Eligible Gender: | All |
Healthy Volunteers: | No |
Primary Outcome Measures
Measure: | Incidence of treatment-emergent adverse events of CG-806 |
Time Frame: | At the end of Cycle 1 (each cycle is 28 days) |
Safety Issue: | |
Description: | Patients will be assessed for adverse events during all cycles of treatment and for dose limiting toxicities in Cycle 1 (28-days). Dose escalation to a higher dose level will be considered if none of the first three patients who complete Cycle 1 (28-days) at a given dose level experience a dose limiting toxicity or if only 1 of 6 patients at a given dose level experience a dose-limiting toxicity. |
Secondary Outcome Measures
Measure: | Pharmacokinetics variables including maximum plasma concentration (Cmax) |
Time Frame: | At the end of Cycle 1 (each cycle is 28 days) |
Safety Issue: | |
Description: | Pharmacokinetics variables including maximum plasma concentration (Cmax) |
Measure: | Pharmacokinetics variables including minimum plasma concentration (Cmin) |
Time Frame: | At the end of Cycle 1 (each cycle is 28 days) |
Safety Issue: | |
Description: | Pharmacokinetics variables including minimum plasma concentration (Cmin) |
Measure: | Pharmacokinetics variables including area under the curve (AUC) |
Time Frame: | At the end of Cycle 1 (each cycle is 28 days) |
Safety Issue: | |
Description: | Pharmacokinetics variables including area under the curve (AUC) |
Measure: | Pharmacokinetics variables including volume of distribution |
Time Frame: | At the end of Cycle 1 (each cycle is 28 days) |
Safety Issue: | |
Description: | Pharmacokinetics variables including volume of distribution |
Measure: | Pharmacokinetics variables including clearance |
Time Frame: | At the end of Cycle 1 (each cycle is 28 days) |
Safety Issue: | |
Description: | Pharmacokinetics variables including clearance |
Measure: | Pharmacokinetics variables including serum half-life |
Time Frame: | At the end of Cycle 1 (each cycle is 28 days) |
Safety Issue: | |
Description: | Pharmacokinetics variables including serum half-life |
Measure: | To assess patients for evidence of anti-tumor activity of CG-806 based on hematologic, bone marrow, physical examination, and FDG PET-CT imaging evaluations |

Safety Issue: | |
Description: | To assess patients for evidence of anti-tumor activity of CG-806 based on hematologic, bone marrow, physical examination, and FDG PET-CT imaging evaluations. |
Measure: | To determine the ability of CG-806 to modulate the expression or activity of pharmacodynamic biomarkers of drug effect. |
