Basket Study of AB-106 for the Treatment of Patients With Solid Tumors With NTRK Fusion Gene

• Status: Recruiting
• Trial end date: 2026-12-31
• Target enrollment: 0
• Participant gender: All

Summary

AB-106 will be administered once a day. Each treatment cycle is defined as 21 days of continuous medication. Dosing will continue until any of the following conditions are met: disease progression, intolerable drug-related adverse events, researchers recommend discontinuation of treatment, withdrawal of informed consent, pregnancy during the study, use of other anti-tumor therapy, loss of follow-up, death and other causes, whichever occurs first.

The study includes a screening period, treatment period, safety follow-up and long-term follow-up.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

5. Pneumonia caused by interstitial lung disease, interstitial fibrosis, or tyrosine kinase inhibitors;

6. Active and uncontrollable systemic bacterial, viral or fungal infectionsx;

7. Clinically active viral disease with positivity of serum HIV, HBV, HCV testing;

8. Historical immunodeficiency, including acquired, congenital immunodeficiency diseases, or a historical organ transplant;

9. The systematically use of strong CYP3A inhibitors, including ( but not limited to) atazanavir, clarithromycin, indinavir, itraconazole, ketoconazole, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, troleandomycin, voriconazole, grapefruit or grapefruit juice;

10. The systematically use of strong CYP3A inducers, including ( but not limited to) carbamazepine, phenobarbital, phenytoin, rifampicin, rifampicin and St. John's grass;

11. Any other anti-tumor drug use within 14 days before first dose or during the study;

12. Historical, neurological or mental disorders, such as epilepsy or dementia;

13. Historical drug abuse;

14. Spinal cord compression caused by tumor (unless the subject's pain is completely controlled and neurological function is stable or restored),cancerous meningitis or leptomeningeal disease; have risk of cerebral hernia determined by investigator;

15. Active gastrointestinal or other malabsorption disease, such as gastrectomy or enterectomy;

16. With 3 months before first dose, have unstable cardiovascular disease like as, myocardial infarction, severe / unstable angina pectoris, coronary artery / peripheral artery bypass grafting, congestive heart failure (NCICTCAEv5.0 ≥ 3), arrhythmia (NCICTCAEv5.0 ≥ 2), uncontrollable atrial fibrillation (arbitrary grade) or female QTcF > 470ms or male QTcF > 450ms;

17. Cerebrovascular accidents (exclude transient ischemic attacks) occurred within 3 months before first dose;

18. Other malignant tumors, exclude cured non-melanoma skin cancer, cervical cancer in situ and prostatic intraepithelial neoplasia;

19. Other protocol specified criteria accessed by investigator.
