Clinical Trial Summary

This is an open-label phase 1 study with an escalation part and an expansion part.

Description:

The escalation part will evaluate the safety, tolerability, PK and recommended dose of expansion (RDE) of oral ABSK-011 in patients with advanced solid tumors. The expansion part of oral ABSK-011 at RDE will be followed for further evaluating safety and tolerability in patients with FGF19 overexpression advanced HCC. Preliminary antitumor activity will also be assessed.

Inability to take oral medication or other factors significant preclude adequate absorption of oral medication, such as previously received total gastrectomy, residual gastric dysfunction after subtotal gastrectomy, short bowel syndrome after small bowel resection, active diarrhea required drug treatment, etc.

7. Severe irritable bowel syndrome requires drug therapy.

8. Prior organ transplantation requires anti-rejection drug therapy.

9. Previous anti-cancer therapy prior to initiation of study treatment: major surgery (except palliative therapy), radiotherapy (bone-marrow exposure >30%), routine chemotherapy <4 weeks (chemotherapy with nitrosourea or mitomycin <6 weeks); oral chemotherapy, endocrine therapy, molecular targeted therapy or immunotherapy within = 5 half-life or = 4 weeks (whichever is shorter).

10. Prior toxicities from chemotherapy, radiotherapy, and other anti-cancer therapies, including immunotherapy that have not regressed to Grade =1 severity (CTCAE v5.0) with the exception of which inclusion criteria allowed, alopecia, vitiligo and neurotoxicity Grade =2 that investigator believe don't affect safety assessment.

11. Concomitant use of strong inhibitors or inducers of CYP3A4 (include grapefruit juice, grapefruit hybrids, pomegranates, starfruit, pomelos, Seville oranges or juice or products) within at least 14 day prior to the first dose of the study drug.

12. Impaired cardiac function or clinically significant cardiac disease, including any one of the following:

1. New York Heart Association class III or IV congestive heart failure, unstable angina, or myocardial infarction within 6 months before administration of the study drug;

2. Clinically significant cardiac arrhythmia requiring active therapy;

3. Uncontrolled hypertension;

4. Left ventricle ejection fraction<50%

5. Prolongation of QTcF (average of three times of examine, male > 450 ms, female > 470 ms) (Note: QTc interval corrected by Frederica's formula) at screening, and other ECG abnormalities with clinical significant by the judge of the investigator.

13. Active infection or unexplained fever > 38.5?.

14. Active or record of gastrointestinal bleeding within 6 months (e.g. esophageal varices or ulcer bleeding).

15. Patients with active HCV infection (HCV-RNA>103 copies/mL or following local clinical practice) and require concomitant anti-HCV therapy during the study; or HBV HCV co-infection.

16. History of immunodeficiency, including HIV serum test positive, or other acquired/congenital immunodeficiency disease, or active tuberculosis.

17. Any other clinically significant comorbidities, such as respiratory, metabolic, congenital, endocrine or central nervous system disease, or any other medical conditions, mental disturbances or social determinants, which in the judgment of the Investigator, could compromise compliance with the protocol, interfere with the interpretation of study results, or predispose the patient to safety risks
