To evaluate the efficacy and safety of venetoclax, chidamide, and chiglitazar sodium (VCC) in patients with relapsed or refractory acute myeloid leukemia (R/R AML).
This is a multicenter, prospective, single-arm clinical study evaluating the efficacy and safety of venetoclax, chidamide, and chiglitazar sodium (VCC) in patients with relapsed or refractory acute myeloid leukemia (R/R AML). Participants will receive VCC combination therapy according to the study protocol. The primary objective is to evaluate the antileukemic efficacy of the VCC regimen, while safety and tolerability will also be assessed throughout the study.
3,667 studies on the registry are indexed under Leukemia, Myeloid, Acute; 816 are open to participants now.
This study's planned enrollment of 30 is below the median of 40 across 3,005 interventional studies indexed under Leukemia, Myeloid, Acute.

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
After a transplant from a donor, the donor’s immune cells attack the recipient’s body, often the skin, gut or liver.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Chidamide, venetoclax, chiglitazar sodium.
Drug: venetoclax, chidamide, and chiglitazar sodium (VCC)
Participants will receive oral chidamide 30 mg twice weekly for 2 weeks, venetoclax 200 mg once daily for 2 weeks, and chiglitazar sodium 48 mg once daily on Days 1-28 of each 28-day cycle. At least two cycles will be administered. Dose modifications are permitted according to clinical condition, laboratory findings, adverse events, and venetoclax plasma concentrations.
Composite Complete Remission Rate (CR + CRi)
The proportion of participants who achieve complete remission (CR) or complete remission with incomplete hematologic recovery (CRi) following VCC treatment. Treatment response will be assessed according to the response criteria specified in the study protocol.
Time frame: Up to 12 months
1-Year Progression-Free Survival (PFS)
The proportion of participants who are alive without disease progression at 1 year after initiation of VCC treatment. Progression-free survival is defined as the time from initiation of study treatment to disease progression or death from any cause, whichever occurs first.
Time frame: Up to 12 months

Time frame: Up to 12 months
Change in Health-Related Quality of Life Assessed by EQ-5D-5L
Health-related quality of life will be assessed using the EuroQol 5-Dimension 5-Level (EQ-5D-5L) questionnaire. Changes in patient-reported health status during treatment will be evaluated relative to baseline.
Time frame: Up to 24 months
Incidence of Adverse Events
The incidence and severity of adverse events occurring during study treatment will be assessed based on clinical symptoms, physical examinations, vital signs, laboratory findings, and other clinically relevant safety parameters. Adverse events will be graded according to the toxicity grading criteria specified in the study protocol.
Time frame: Up to 12 months
Start is estimated for Nov 2026; primary completion for Mar 2028, 16 months later.
Of 385 non-industry phase 2 interventional studies under Leukemia, Myeloid, Acute, half reached primary completion within 67 months of starting (the median), counting those still running; a quarter within 40 and three quarters within 108. This study's planned 16 months is below that.
Counting every sponsor, half of 442 studies reached it within 60 months; a quarter within 38 and three quarters within 104.
