Study Description

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.

Condition or Disease Intervention/Treatment Phase
Phase 1

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.

Outcome Measures

Primary Outcome Measures

  1. To evaluate the Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] with BTX-1188 in subjects with advanced malignancies [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

  2. To determine the recommended Phase 2 dose (RP2D) of BTX-1188 in subjects with advanced malignancies [At the end of Cycle 1 (each cycle is 28 days)]

    To assess number of patients experiencing dose-limiting toxicities (DLTs)

Secondary Outcome Measures

  1. 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).]

    To evaluate the maximum observed concentration (Cmax) after single and repeated oral, once daily doses of BTX-1188

  2. 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).]

    To evaluate the observed time of peak concentration (Tmax) after single and repeated oral, once daily doses of BTX-1188

  3. 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).]

    To evaluate the area under the curve (AUC) plasma-concentration after single and repeated oral, once daily doses of BTX-1188.

  4. 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).]

    To evaluate the half-life of BTX-1188 after single and repeated oral, once daily doses of BTX-1188.

  5. Objective response rate (ORR) [Up to 2 years after the last treatment or upon death.]

    To evaluate the objective response rate (ORR) as determined by the specific disease response criteria.

  6. 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.]

    To evaluate the complete remission/response [CR], CR with incomplete blood count recovery [CRi], morphologic leukemia free state [MLFS], partial remission/response [PR], stable disease or progression as determined by the specific disease response criteria.

  7. 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.]
