Purpose:

This is a first-in-human, phase I clinical research study with TT-00420, an investigational, oral, multi-target, dual mechanism kinase inhibitor targeting both mitosis and tumor micro-environment, for the treatment of triple negative breast cancer (TNBC) and other advanced solid tumors. The study consists of a dose escalation part followed by a MTD expansion part.


Study summary:

Dose Escalation Cohorts: Eligible adult patients with advanced solid tumors will be enrolled into Dose Escalation cohorts. Starting dose of TT-00420 mono-therapy will be 1 mg p.o., q.d. TT-00420 capsule will be administered once daily on a continuous schedule. A treatment cycle consists of 28 days. An ABLRM guided by the EWOC principle will evaluate the risk of under-dose or over-dose for the dose tested in each cohort and provide the recommendation dose for next cohort. Dose limiting toxicity (DLT) will be evaluated per the pre-defined DLT criteria and managed by the pre-defined rules detailed in the protocol. Maximum Tolerated Dose (MTD) and/or Dose Recommend for Dose Expansion (DRDE) will be determined in Dose Escalation cohorts. Dose Expansion Cohorts: TNBC Cohort: TNBC Dose-Expansion cohort will be opened to enroll the patients with advanced TNBC and evaluate the safety, PK and preliminary efficacy of TT-00420 to identify the optimal biological dose (OBD), when feasible, in patients with advanced TNBC. SAT Cohort: A parallel basket SAT Dose Expansion Cohort will be open to enroll patients with selected advanced tumors (SAT) to evaluate the safety, PK and preliminary efficacy of TT-00420 to identify the optimal biological dose (OBD), when feasible, in patients with SATs. Recruitment in dose expansion cohorts may be put on hold if any significant safety finding(s) that was not observed in dose escalation cohorts is identified. Bayesian modeling will be updated with the new findings to evaluate if the previously determined MTD or DRDE still suitable for further enrollment.

Patients with 1. a history of primary central nervous system tumors or 2. carcinomatous meningitis Note: Patients with treated brain metastases that are off corticosteroid and have been clinically stable 28 days are eligible for enrollment 5. Patients with the following mood disorders as judged by the Investigator or a psychiatrist, or as result of patient's mood assessment questionnaire: - Medically documented history of or active major depressive episode, bipolar disorder (I or II), obsessive-compulsive disorder, schizophrenia; a history of suicidal attempt or ideation, or homicidal ideation (immediate risk of doing harm to others) - ≥ CTCAE grade 3 anxiety - The psychiatric judgment, if available, overrules the mood assessment questionnaire result/investigator judgment 6. Impaired cardiac function or clinically significant cardiac diseases, including but not limited to any of the following: 1. LVEF < 45% as determined by MUGA scan or ECHO 2. Congenital long QT syndrome 3. QTc ≥ 450 msec on screening ECG 4. Unstable angina pectoris ≤ 3 months prior to starting study drug 5. Acute myocardial infarction ≤ 3 months prior to starting study drug 7. Patients with 1. unresolved diarrhea ≥ CTCAE grade 2, or 2. impairment of gastrointestinal (GI) function, or 3. GI disease that may significantly alter the absorption of TT-00420 (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection). 8. Other concurrent severe and/or uncontrolled concomitant medical conditions (e.g., uncontrolled hypertriglyceridemia [triglycerides > 500 mg/dL], active or uncontrolled infection) that could cause unacceptable safety risks or compromise compliance with the protocol 9. Patients who have received chemotherapy, targeted therapy or immunotherapy ≤ 4 weeks (6 weeks for nitrosourea or mitomycin-C) prior to starting study drug or who have not recovered from side effects of such therapy 10. Patients who have received wide field radiotherapy ≤ 4 weeks or limited field radiation for palliation ≤ 2 weeks prior to starting study drug or who have not recovered from side effects of such therapy 11.
