Overview
Brief Summary
This is a multicenter, open label, nonrandomized, sequential dose escalation, multiple dose study designed to evaluate the safety, toxicity, and pharmacokinetics (PK) as well as preliminary efficacy of BTX-1188 orally administered in subjects with advanced malignancies.
Detailed Description
Study BTX-1188-001 is a multicenter, open label, nonrandomized, sequential dose escalation study to evaluate the safety, toxicity, PK, and preliminary efficacy of BTX-1188. Dose escalation will be conducted in subjects with acute myeloid leukemia (AML) and advanced lymphoid and solid tumors. Based on the results of the dose escalation, a recommended Phase 2 dose will be determined.

Eligibility Criteria
Inclusion Criteria
- •Demonstration of understanding and voluntarily signing of an informed consent form
- •Age ≥ 18 years
- •Part A - Relapsed or refractory AML, according to the World Health Organization (WHO) classification (Arber, Orazi, et al., 2016). Subjects must be ineligible for or have exhausted standard therapeutic options that would otherwise be likely to provide clinical benefit. Part B - B cell NHL that is refractory to or intolerant of all standard therapy or for which no standard therapy is available or histologically or cytologically documented, incurable or metastatic solid tumor that has failed all available standard therapies with known benefit.
- •Subjects with solid tumors must have measurable disease per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1). NHL subjects must have bi-dimensionally measurable disease on cross sectional imaging by computed tomography (CT) or magnetic resonance imaging (MRI) as defined by Lugano criteria (Cheson, Fisher, et al., 2014).
- •Adequate organ function
- •Females must avoid pregnancy for at least 4 weeks before beginning BTX-1188 therapy, during therapy, during dose interruptions, and for at least 4 weeks after completing therapy and agree to either abstain from sexual intercourse or use two highly effective methods of contraception (for up to 4 weeks after last dose of study drug)
- •Males sexually active with a woman of childbearing age must agree to use barrier method of birth control during and after the study and not donate sperm (for up to 4 weeks after last dose of study drug).
Exclusion Criteria
- •Life expectancy \<3 months, as determined by the Investigator.
- •Treatment with any local or systemic antineoplastic therapy (including chemotherapy, hormonal therapy, or radiation) within 3 weeks prior to first dose of BTX-1188
- •Immediate life-threatening severe complications of leukemia such as uncontrolled bleeding, pneumonia with hypoxia or shock, and/or disseminated intravascular coagulation
- •Major trauma or major surgery within 4 weeks prior to first dose of BTX-
- •Adverse events from prior anti-cancer therapy that have not resolved to Grade ≤1 except for alopecia or Grade ≤2 immunotherapy-related thyroid toxicity.
- •History of, or known, central nervous system (CNS) disease involvement, or prior history of NCI CTCAE Grade ≥3 drug-related CNS toxicity.
- •Clinically significant cardiac disease
- •Active uncontrolled systemic fungal, bacterial, mycobacterial, or viral infection
- •Known positive test result for human immunodeficiency virus (HIV) or acquired immune deficiency syndrome (AIDS)
- •Active hepatitis C virus (HCV) or hepatitis B virus (HBV)

Outcomes
Primary Outcomes
To determine the recommended Phase 2 dose (RP2D) of BTX-1188 in subjects with advanced malignancies
Time Frame: At the end of Cycle 1 (each cycle is 28 days)
To assess number of patients experiencing dose-limiting toxicities (DLTs)
To evaluate the Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] with BTX-1188 in subjects with advanced malignancies
Time Frame: From first dose of BTX-1188 through 30 days after the last BTX-1188 treatment
To examine the incidence of clinical and laboratory adverse events after multiple doses of BTX-1188
Secondary Outcomes
- Half-life of BTX-1188(PK samples are collected at pre-dose and post-dose at 1, 2, 3, 5, and 8 hours on Days 1 and 5 of Cycle 1 (each cycle is 28 days).)
- Disease Control Rate (DCR)(For subjects with AML, response will be evaluated at the end of each cycle (each cycle is 28 days) and after the last dose of BTX-1188 (approximate 36 months). For subjects with NHL or solid tumors, response will be evaluated every 8-weeks.)
- Duration of response (DoR)(Up to 2 years after the last treatment or upon death.)
- Progression free survival (PFS)(Up to 2 years after the last treatment or upon death.)
- Maximum Plasma Concentration of BTX-1188(PK samples are collected at pre-dose and post-dose at 1, 2, 3, 5, and 8 hours on Days 1 and 5 of Cycle 1 (each cycle is 28 days).)
- Peak Plasma Concentration of BTX-1188(PK samples are collected at pre-dose and post-dose at 1, 2, 3, 5, and 8 hours on Days 1 and 5 of Cycle 1 (each cycle is 28 days).)
- Area under the plasma concentration of BTX-1188(PK samples are collected at pre-dose and post-dose at 1, 2, 3, 5, and 8 hours on Days 1 and 5 of Cycle 1 (each cycle is 28 days).)
- Objective response rate (ORR)(Up to 2 years after the last treatment or upon death.)
- Overall survival (OS)(Up to 2 years after the last treatment or upon death.)
- Best response(For subjects with AML, response will be evaluated at the end of each cycle (each cycle is 28 days) and after the last dose of BTX-1188 (approximately 36 months). For subjects with NHL or solid tumors, response will be evaluated every 8-weeks.)
