Summary

This is a first-in-human (FIH), multicenter, open-label Phase I dose escalation study to evaluate the safety and preliminary efficacy of the TT-01488 tablet, a non-covalent reversible BTK inhibitor, for the treatment of adult patients with B-cell malignancies.

Description

The study will consist of two parts, dose escalation and dose expansion. A modified 3+3 design will be used to guide the dose escalation and the determination of the dose recommended for dose expansion (DRDE). A sentinel cohort comprising of one subject will be enrolled at a starting dose of 50 mg q.d. Subsequently, patients will be enrolled according to the standard 3+3 dose escalation design to determine the DRDE. Once the DRDE has been selected, TT-01488 of DRDE will be further tested in the dose expansion cohort to verify the safety and preliminary efficacy as observed in the dose escalation cohorts. A recommended Phase II dose (RP2D) may be determined based on the totality of safety, pharmacokinetics, and efficacy data from the dose escalation cohorts and dose expansion cohort.

Exclusion Criteria

Women who are pregnant or lactating
Prior malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or other cancer from which the subject has been disease-free for at least 2 years or which will not limit survival to < 2 years (Note: these cases must be discussed with the Medical Monitor and/or Investigator)
A life-threatening illness, medical condition, or organ system dysfunction which, in the investigator's opinion, could compromise the subject's safety, interfere with the absorption or metabolism of TT-01488, or put the study outcomes at undue risk
Significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias, congestive heart failure, or myocardial infarction within 6 months of screening, or significant screening ECG abnormalities including left bundle branch block, 2nd degree AV block type II, 3rd degree block, bradycardia, and corrected QT interval using Fridericia's Formula (QTcF) > 470 msec, or any Class 3 or 4 cardiac disease as defined by the New York Heart Association Functional Classification
Malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel or ulcerative colitis, symptomatic inflammatory bowel disease, or partial or complete bowel obstruction
Any immunotherapy, , radiotherapy (limited-field radiation for palliation within 7 days), or experimental therapy within 4 weeks, or 5-half lives for chemotherapy and small molecule agents (whichever is shorter), before first dose of study drug (corticosteroids for disease-related symptoms allowed but require 1-week washout before study drug administration)

following

Proton pump inhibitors, histamine-2 blockers (H2 blockers), and locally acting antacids (Note: For patients who are dependent upon this class of medications, patients may be considered after consulting with the study investigator and Sponsor. See Section 6.4.2 for more details)
Central nervous system involvement by lymphoma
Grade ≥ 2 toxicity (other than alopecia) continuing from prior anticancer therapy, including radiation
Known history of Human Immunodeficiency Virus (HIV) or active infection with Cytomegalovirus (CMV), Hepatitis C Virus (HCV) or Hepatitis B Virus (HBV), or any uncontrolled active systemic infection
