Clinical Trial Summary

Phase 1/1b, open label, multi-center dose escalation and dose expansion study designed to evaluate safety, tolerability, PK (pharmacokinetics), PD (pharmacodynamics) and anti-tumor effects of ALRN-6924 alone or in combination with cytarabine in patients with relapsed/refractory acute myeloid leukemia or advanced myelodysplastic syndrome with wild-type (WT) TP53


Description:

Phase I, open label, multi-center dose escalation (DEP) and dose expansion (EXP) study designed to evaluate safety, tolerability, PK (pharmacokinetics), PD (pharmacodynamics) and anti-tumor effects of ALRN-6924 in patients with acute myeloid leukemia or advanced myelodysplastic syndrome with wild-type (WT) TP53. ALRN-6924 is a stabilized cell-permeating peptide designed to disrupt interaction between the p53 tumor suppression protein and its endogenous inhibitors murine double minute 2 (MDM2) and murine double minute X (MDMX)

Men and women 18 years of age and older with relapsed or refractory acute myeloid leukemia or advanced myelodysplastic syndrome and for which standard treatment(s) are not available or are no longer effective can be enrolled. Treatment of patients in the DEP and EXP phases will continue in the study until documentation of disease progression, unacceptable toxicity, or patient or physician decision to discontinue study participation is made.

Study Design


Intervention

Drug:
ALRN-6924
Fixed dose of ALRN-6924 per cohort, administered IV, Days 1, 8, and 15 every 28 days.
ALRN-6924 in combination with cytarabine
Cytarabine (100 or 200 mg/m2) will be administered as an IV infusion followed by ALRN-6924 on Days 1, 8, and 15 every 28 days.

Outcome

Type Measure Description Time frame Safety issue
Primary Evaluate the safety and tolerability of ALRN-6924 alone and in combination with cytarabine Number of participants with treatment-related adverse events as assessed by CTCAE v.4.0 From Day 1 of treatment until 30 days after the last cycle of treatment (each cycle is 28 days)
Primary Determine maximum tolerated dose (MTD) Determine the dose limiting toxicities (DLT) and the maximum tolerated dose (MTD) or the optimal biological dose (OBD) of ALRN-6924 in adult patients with AML or MDS From the first dose until the end of Cycle 2 (each cycle is 28 days)
Secondary Determine PK parameters of ALRN-6924 when administered to patients with acute myeloid leukemia (AML) or advanced myelodysplastic syndrome (MDS) Peak Plasma Concentration (Cmax) First 2 cycles (each cycle is 28 days)
Secondary Determine PK parameters of ALRN-6924 when administered to patients with acute myeloid leukemia (AML) or advanced myelodysplastic syndrome (MDS) Area under the plasma concentration versus time curve [AUC] First 2 cycles (each cycle is 28 days)
Secondary Determine immunogenicity of ALRN-6924 Incidence of anti-ALRN-6924 antibodies Approximately 16 weeks
Secondary Determine best overall response, duration of response, morphologic leukemia-free state, leukemia free survival, percentage of MDA patients who have achieved hematologic improvement, changes in transfusion rate and early death rate International Working Group (IWG) Criteria (Cheson et al, 2006) Approximately 16 weeks
Secondary Determine best overall response, duration of response, morphologic leukemia-free state, leukemia free survival, percentage of MDA patients who have achieved hematologic improvement, changes in transfusion rate and early death rate AML response criteria (Dohner et al, 2010) Approximately 16 weeks
Secondary Determine best overall response, duration of response, morphologic leukemia-free state, leukemia free survival, percentage of MDA patients who have achieved hematologic improvement, changes in transfusion rate and early death rate International Working Group (IWG) Criteria for hematological improvement in MDS (Cheson et al, 2000) Approximately 16 weeks
