-
A history of additional risk factors for Torsades de Pointes(TdP) (e.g., heart failure, hypokalemia, family history of Long QT Syndrome).
-
The use of concomitant medications that prolong the QT/QTc interval.
-
Concomitant use or recent use (at least 2 weeks before the start of ZX-4081 treatment) of drugs that are known to be strong CYP3A4/5 inhibitors and CYP3A4/5 inducers (See 5.4.2 for a list of study medications not allowed during this study).
-
Concomitant use of drugs that are sensitive substrates with narrow therapeutic index for one of the following: CYP2C9, CYP2C19, CYP2C8, CYP2D6 and CYP3A4 (See 5.4.2 for a list of study medications not allowed during this study).
-
Concomitant use of drugs that are sensitive substrates with narrow therapeutic index for one of the following transporters: P-glycoprotein (P-gp) and Breast Cancer resistance Protein (BCRP).
-
Recent use a proton pump inhibitor (within 4 days prior to the start ZX-4081 treatment) or a histamine H2 blocker (within 2 days prior to the start of ZX-4081 treatment).
-
Uncontrolled concurrent illness.
-
Patient has concurrent active malignancy other than nonmelanoma skin cancer, carcinoma in situ of the cervix, or superficial bladder cancer who has undergone potentially curative therapy with no evidence of disease. Patients with other previous malignancies are eligible if disease-free for >2 years.
-
Participation in another clinical trial of an investigational agent within 30 days of screening.
-
Patient has known psychiatric, substance abuse or other disorders that would interfere with cooperation with the requirements of the trial, in the opinion of the investigator.
-
Patients who are pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 30 days after the last dose of trial treatment.

Group Intervention Description ZX-4081 Dose Level 1 ZX-4081 Starting dose (SD) of ZX-4081 administered orally twice daily (BID) in a 28-day cycle ZX-4081 Dose Level 2 ZX-4081 2-times the SD of ZX-4081 administered orally BID in a 28-day cycle ZX-4081 Expansion Dose Level ZX-4081 Recommended Phase 2 Dose (RP2D) (to be determined) of ZX-4081 administered orally BID in a 28-day cycle ZX-4081 Dose Level 3 ZX-4081 4-times the SD of ZX-4081 administered orally BID in a 28-day cycle ZX-4081 Dose Level 4 ZX-4081 6-times the SD of ZX-4081 administered orally BID in a 28-day cycle ZX-4081 Dose Level 5 ZX-4081 8-times the SD of ZX-4081 administered orally BID in a 28-day cycle ZX-4081 Dose Level 6 ZX-4081 10-times the SD of ZX-4081 administered orally BID in a 28-day cycle
- Primary Outcome Measures
Name Time Method Determine the recommended Phase 2 dose (RP2D) of ZX-4081 At the end of Cycle 1 (each cycle is 28 days) To assess number of patients experiencing dose-limiting toxicities (DLTs) in the dose escalation phase
Safety and tolerability of ZX-4081 From first dose of ZX-4081 through 28 days after the last ZX-4081 treatment (up to 2 years); each cycle is 28 days To examine the incidence of clinical and laboratory adverse events after multiple doses of ZX-4081 in the dose escalation and dose expansion phases
- Secondary Outcome Measures
Name Time Method Half-life of ZX-4081 Days 1, 8, and 15 of Cycle 1 (each cycle is 28 days) To evaluate the half-life of ZX-4081 after single and repeated oral, BID doses of ZX-4081
Peak Plasma Concentration of ZX-4081 Days 1, 8, and 15 of Cycle 1 (each cycle is 28 days) To evaluate the maximum observed concentration (Cmax) after single and repeated oral, twice daily (BID) doses of ZX-4081
Area under the plasma concentration of ZX-4081 Days 1, 8, and 15 of Cycle 1 (each cycle is 28 days) To evaluate the area under the curve (AUC) plasma-concentration after single and repeated oral, BID doses of ZX-4081
Peripheral myeloid-derived suppressor cell (MDSC) proportion in the blood Cycle 1 Day1 , Cycle 2 Day 1, and Cycle 3 Day 1 (each cycle is 28 days) To assess the changes of peripheral MDSC proportion in the blood after single and repeated oral, BID doses of ZX-4081
Objective response rate (ORR) Up to 2 years To evaluate the objective response rate (ORR) as determined by the specific disease response criteria
Duration of Response (DOR) Up to 2 years To examine the duration of response (DoR), defined as time from the date of first documentation of response to the date of the first documentation of progressive disease (PD), or death due to any cause
Overall Survival (OS) Up to 2 years To examine the overall survival (OS), defined as time from the date of first dose of study treatment to death due to any cause
T cell composition and activation status Cycle 1 Day1 , Cycle 2 Day 1, and Cycle 3 Day 1 (each cycle is 28 days) To assess the impact on T cell profiles after repeated oral, BID doses of ZX-4081
