Clinical Trial Summary

T-1101 (Tosylate) is a new small molecule chemical entity being developed as a potential anti-cancer therapeutic by Taivex Therapeutics Corp. T-1101 (Tosylate) is a potent anti-cancer agent in numerous human cancer cell lines. In addition, oral administration of T-1101 (Tosylate) showed tumor growth inhibition in different mouse xenograft models of human cancers. In this study, safety, tolerability and pharmacokinetic (PK) of T-1101 (Tosylate) capsules will be evaluated and also the recommended dose and regimen(s) to initiate Phase 2 will be determined.

8. Adequate organ function as defined by the following criteria:

1. Serum aspartate transaminase (AST) and serum alanine transaminase (ALT) = 3 x upper limit of normal (ULN), or AST and ALT = 5 x ULN if liver function abnormalities are due to underlying malignancy

2. Total serum bilirubin = 1.5 x ULN

3. Absolute neutrophil count (ANC) = 1500/µL

4. Platelets = 100,000/µL

5. Hemoglobin = 9.0 g/dL

6. Creatinine clearance (CrCl) = 50 mL/min CrCl = [(140 - age (year)) x weight (kg)] / (serum creatinine x 72) (x 0.85 for females)

9. Willingness and ability to comply with the study scheduled visits, treatment plans, laboratory tests and other procedures.

Exclusion Criteria:

1. Major surgery within 4 weeks prior to starting T-1101 (Tosylate).

2. Subjects received any of the following anti-cancer therapies:

1. Anti-cancer radiation therapy within 2 weeks prior to starting T-1101 (Tosylate).

2. Palliative radiation (= 10 fractions) within 48 hours prior to the screening

3. Any systemic cytotoxic chemotherapy within 2 weeks or 5 half-lives (whichever is greater) prior to starting T-1101 (Tosylate)

4. Any target therapy within 2 weeks prior to starting T-1101 (Tosylate)

3. Any interventional treatments in another clinical trial within 2 weeks or 5-half-lives (whichever is greater) prior to starting T-1101 (Tosylate)

4. Documented or suspected brain metastases, spinal cord compression, carcinomatous meningitis, or leptomeningeal disease

5. Any of the following within 6 months of starting study treatment: myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass graft, congestive heart failure, or cerebrovascular accident including transient ischemic attack

6. Ongoing cardiac dysrhythmias of = NCI CTCAE v5.0 grade 2, or atrial fibrillation of any grade

7. Hypertension that cannot be controlled by medications (> 160/100 mm-Hg despite optimal medical therapy).

8. Known human immunodeficiency virus (HIV) infection

9. A positive test for hepatitis B (HBsAg) or hepatitis C (anti-HCV (hepatitis C virus) antibody), unless the HBV (hepatitis B virus) DNA level and/or HCV RNA level is below the limit of detection.

10. Men and women of childbearing potential who are unwilling to use highly effective contraceptive methods during the study period. Highly effective contraceptive methods include implants, injectables, combined oral contraceptives, intra-uterine devices (IUDs), sexual abstinence, surgical sterilization or a partner who is sterile.

11. If females, patient is pregnant or breastfeeding

12. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that would impart, in the judgement of the investigator and/or sponsor, excess risk associated with study participation or study drug administration

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum Tolerated Dose (MTD) of T-1101 (Tosylate) in Participants with Advanced Cancers Refractory to Standard Therapy	MTD is highest dose level of 30% target toxicity rate and the MTD will be determined based on the occurrence of the dose-limiting toxicity (DLT) assessed using toxicity data during Cycle 1 (the first 28 days).; When following toxicity events occur within the first 28-day cycle, these toxicity will be defined as DLT.; Hematological toxicities : prolonged grade 4 neutropenia for >7 days, grade 3 febrile neutropenia (an ANC < 1000/mm3 with a single temperature of > 38.3°C or a sustained temperature of > 38°C for more than 1 hour), grade 4 febrile neutropenia (febrile neutropenia with life-threatening consequences; urgent intervention indicated), Grade 3 or 4 neutropenia with IV treatment for infection and grade 3 thrombocytopenia with bleeding or grade 4 lasting 7 days.; Non-hematological toxicities: grade 3 or 4 toxicities, Nausea and vomiting or diarrhea must persist at grade 3 or 4 despite maximal medical therapy.	The first 28-day cycle
Secondary	Pharmacokinetics: Area under the plasma concentration versus time curve (AUC) to the time of the last measurable concentration and to infinity of T-1101 (Tosylate)	Area under the plasma concentration versus time curve to the time of the last measurable concentration (AUC0-last) of T-1101 (Tosylate) will be estimated using non-compartmental analysis. If data permit, area under the plasma concentration versus time curve to infinity (AUC0-8) will be also estimated.	Selected time points during first 28-day cycle
Secondary	Pharmacokinetics: Time to maximum plasma concentration (Tmax) and terminal half-life (T½) of T-1101 (Tosylate)	Time to maximum plasma concentration (Tmax) of T-1101 (Tosylate) will be estimated using non-compartmental analysis. If data permit, terminal elimination half-life (T½ ) will be also estimated.	Selected time points during first 28-day cycle
Secondary	Pharmacokinetics: Oral plasma clearance (CL/F) of T-1101 (Tosylate)	Oral plasma clearance (CL/F) of T-1101 (Tosylate) will be estimated using non-compartmental analysis.	Selected time points during first 28-day cycle
Secondary	Pharmacokinetics: Apparent volume of distribution (Vd/F) of T-1101 (Tosylate)	Apparent volume of distribution (Vd/F) of T-1101 (Tosylate) will be estimated using non-compartmental analysis.	Selected time points during first 28-day cycle
Secondary	Clinical Tumor Response of T-1101 (Tosylate) in Participants with Advanced Cancers	Categorization of response based on RECIST 1.1.	Up to 2 years
