A Study of HS-10382 in Patients With Chronic Myeloid Leukemia.

Summary

HS-10382 is a small molecular, oral potent, allosteric inhibitor. By binding a myristoyl site of the BCR-ABL1 protein, HS-10382 locks BCR-ABL1 into an inactive conformation. The purpose of this study is to investigate the safety/tolerability and the pharmacokinetic(PK) profile of HS-10382 in patients with chronic myeloid leukemia (CML). Anti-CML activity will also be investigated in this study.

Eligibility

Inclusion Criteria:

1. Signed informed consent form.
2. Men or women aged more than or equal to (≥) 18 years, and less than (\<) 75 years.
3. CML-CP/AP patients with the Ph chromosome or BCR-ABL1 fusion genes.
4. Patient with CML-CP/AP who are resistant to or intolerant to previous TKIs therapy.
5. ECOG performance status of 0-2.
6. Life expectancy ≥ 12 weeks.
7. Men or women should be using adequate contraceptive measures throughout the study; Females should not be breastfeeding at the time of screening, during the study and until 6 months after completion of the study.
8. Females must have evidence of non-childbearing potential.

Exclusion Criteria:

1. CML-CP patients who have acquired CCyR and have not lost it.
2. Patients with CML-CP who have progressed to AP or blast phase(BP.)
3. Patients with CML-AP who have obtained CHR or no evidence of CML in peripheral blood.
4. Patients with CML-AP who have progressed to BP.
5. Previous treatment with a BCR-ABL1 TKI allosteric inhibitor .
6. Impaired cardiac function including any one of the following:

   1. Resting corrected QT interval (QTc) \> 470 ms obtained from electrocardiogram (ECG), using the screening clinic's ECG machine and Fridericia's formula for QT interval correction (QTcF).
   2. Any clinically important abnormalities in rhythm, conduction, or morphology of the resting ECG.
   3. Any factors that increase the risk of QTc prolongation or risk of arrhythmic events,
   4. Left ventricular ejection fraction (LVEF) ≤ 50%.
   5. During screening period, ECG examination showed average heart rate \<50 beats per minute.
   6. Myocardial infarction occurred within 6 months of the first scheduled dose of HS-10382.;
   7. Congestive heart failure occurred within 6 months of the first scheduled dose of HS-10382.;
   8. Uncontrollable angina.
7. History of acute pancreatitis within 1 year of study entry or past medical history of chronic pancreatitis
8. Any severe or uncontrolled systemic diseases (i.e. uncontrolled hypertension or diabetes).
9. Clinically severe gastrointestinal dysfunction that may affect drug intake, transport or absorption.
10. Severe infection within 4 weeks prior to the first scheduled dose of HS-10382.
11. History of significant congenital or acquired bleeding disorders unrelated to CML.
12. Inadequate other organ function.
13. History of other malignancies.
14. History of hypersensitivity to any active or inactive ingredient of HS-10382.
15. History of neuropathy or mental disorders, including epilepsy and dementia.
16. Judgment by the investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions, and requirements.
