Safety and Tolerability Study for T-1101 (Tosylate) Capsules to Treat Advanced Refractory Solid Tumors

Inclusion Criteria:

1. Having signed and dated informed consent form indicating that the subject has been informed of all pertinent aspects of the study
2. Histologically and cytologically confirmed advanced malignancies that are refractory to standard treatments
3. Solid tumors that are measurable or evaluable as per Response Evaluation Criteria in Solid Tumors (RECIST v1.1). Target lesions that have been previously irradiated will not be considered measurable (lesion) unless increase in size is observed following completion of radiation therapy
4. Have a life expectancy of ≥3 months in the investigator's opinion
5. Females or males ≥ 20 years old
6. ECOG (Eastern Cooperative Oncology Group) performance status of 0 or 1
7. Recovered from prior treatment-related toxicity to at least grade 1 with exception of alopecia
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
