About this trial
Acute myeloid leukemia is a malignant disorder characterized by the rapid, uncontrolled proliferation of malignant clonal hematopoietic stem cells that accumulate as immature, undifferentiated cells (blasts) in the bone marrow and circulation.
APG-115 is a potent and orally active small-molecule MDM2 inhibitor, it binds to MDM2 protein and shows potent cell growth inhibitory activity in vitro with low nanomolar potencies in a subset of human cancer cell lines. APG-115 has demonstrated its strong antitumor activities with either daily or less frequent dosing-schedules in the acute leukemia xenograft models.
This is a phase 1b, open-label, three-stages study that will initially evaluate the safety and PK/PD profile of APG-115 as a single agent, followed by a combination of APG-115 + azacytidine or cytarabine in R/R AML or MDS subjects.
Patients will continue treatment for maximally 6 cycles or until progression of disease or unacceptable toxicity is observed or administrative discontinuation whichever occurs first. Patients who continue to be benefit after 6 cycles' treatment will receive additional cycles of treatment until progression of disease, unacceptable toxicity is observed or administrative discontinuation. (As long as it is proven safe).
Eligibility criteria
Qualifiers
Patients with a diagnosis of histologically confirmed relapsed or refractory (R/R) acute myeloid leukemia by WHO classification or relapsed/progressed high/very high risk MDS (score≥4.5) according to IPSS-R risk stratification
Age >/= 18 years.
Adequate organ function
Subject must have a projected life expectancy of at least 12 weeks.
Disqualifiers
Subject has acute promyelocytic leukemia.
Patients must not have had leukemia biotherapy 4 weeks prior to starting investigational drug, or less than 5 half-lives small molecular targeted drug therapy, or 28 days any anti-cancer therapy (whichever is longer)
Uncontrolled intercurrent illness including, but not limited to active uncontrolled infection, symptomatic congestive heart failure (NYHA Class III or IV), unstable angina pectoris, clinically significant cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
Active infection requiring systemic antibiotic/antifungal medication, known clinically active hepatitis B or C, or HIV infection.
