Clinical Trial Summary

T-1301 is a novel small-molecule inhibitor of multiple kinases being developed as an oral drug for the treatment of advanced solid tumors. The nonclinical study results demonstrate the nonclinical efficacy and safety of T-1301 and support the design of this Phase 1, first-in-human (FIH) clinical trial in subjects with advanced cancer. This study is an open-label, multi-center, Phase I dose-escalation study to evaluate the safety, tolerability, and pharmacokinetics of T-1301 capsules in subjects with advanced solid tumors (including lymphoma), and to identify the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D). Approximately 30 patients will be enrolled for the dose-escalation phase. Actual number of patients will be determined by the number of dose cohorts until the MTD is reached. T-1301 will be administered orally QD or BID in a 28-day cycle (21 days on treatment followed by 7 days off treatment) in sequential cohorts. Subjects can continue with the treatment until one of the discontinuation criteria is met or until the planned stop of the study (12 months after the last subject receives the first dose of study drug), whichever comes first. The planned dose levels are: 10, 20, 40, 60, 80, 100, 120, 140 and 160 mg/day. The dosing schedule will be once daily (QD) at the first dose level (10 mg/day) and be changed to twice daily (BID) starting with the second dose level. Other dose levels or dosing frequency may be explored based on safety and related drug exposure data following the decision of Safety Review Committee. The dose escalation will follow accelerated titration and the Bayesian optimal interval (BOIN) design. During the initial accelerated titration phase, one (1) subject is enrolled per dose level. In the subsequent phase when the BOIN design is used, subjects will be enrolled in cohorts of size 3-6.

Exclusion Criteria:

1. Major surgery within 4 weeks prior to the first dose of study drug.

2. Subjects receiving any of the following anti-cancer therapy:

1. Anti-cancer definitive radiation therapy (4,000-6,000 cGy) within 4 weeks prior to the first dose of study drug.

2. Palliative radiation (= 10 fractions with total dose < 3,000 cGy) within 2 weeks prior to the first dose of study drug.

3. Any systemic cytotoxic chemotherapy within 4 weeks prior to the first dose of study drug.

4. Any targeted therapy within 2 weeks or 5 half-lives, whichever is longer, prior to the first dose of study drug.

5. Any immunotherapy within 4 weeks prior to the first dose of study drug.

3. Any interventional treatments in another clinical trial following Exclusion Criteria 2c, 2d and 2e.

4. Subjects received blood transfusion or biological response modifiers (e.g., G-CSF) within 2 weeks prior to the first dose of study drug.

5. Subject who received autologous bone marrow transplant or stem cells rescue within 6 months prior to the first dose of study drug.

6. Subjects received strong inhibitors and/or inducers of CYP3A4 within 14 days prior to the first dose of study drug. A list of CYP3A4 modulators is provided in Appendix 3.

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

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

9. Ongoing cardiac dysrhythmias of = NCI CTCAE version 5.0 grade 2, or atrial fibrillation of any grade. Corrected QT interval by Fridericia (QTcF) = 470 msec.

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

11. AIDS-defining opportunistic infections within the past 12 months.

12. Positive test for hepatitis B (HBsAg) or hepatitis C (anti-HCV (anti-hepatitis C virus) antibody), unless the HCV RNA level is below the limit of detection (for subjects with positive anti-HCV Ab).

13. 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.

14. If females, patient is pregnant or breast feeding.

15. 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)	The MTD will be selected based on isotonic regression as specified in Liu and Yuan (2015). Specifically, the dose for which the isotonic estimate of the toxicity rate is closest to the target toxicity rate is selected as the MTD. If there are ties, the higher dose level is selected when the isotonic estimate is lower than the target toxicity rate and the lower dose level is selected when the isotonic estimate is greater than or equal to the target toxicity rate. The target toxicity rate for the MTD is 30% 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).	First treatment cycle (i.e., the first 28 days post the first dose)
Primary	Recommended phase 2 dose (RP2D)	The recommended Phase 2 Dose (RP2D) will not exceed the MTD and will be determined by the Safety Review Committee.	First treatment cycle (i.e., the first 28 days post the first dose)
Primary	Frequency, types, severity and relationship to study drug of adverse events (AEs)	Safety and tolerability	At least 84 days (i.e., 56 days for two treatment cycles and 28 days for safety follow-up)
Secondary	Pharmacokinetic parameters: Cmax	The maximum plasma concentration of T-1301 derived from the plasma concentration-time profiles	Selected time points during the first 28-day treatment cycle
Secondary	Pharmacokinetic parameters: Ctrough	The plasma concentration of T-1301 at trough level derived from the plasma concentration-time profiles	Selected time points during the first 28-day treatment cycle
Secondary	Pharmacokinetic parameters: Tmax	The time to reach maximum concentration of T-1301 derived from the plasma concentration-time profiles	Selected time points during the first 28-day treatment cycle
Secondary	Pharmacokinetic parameters: AUC	The area under the concentration versus time curve of T-1301 derived from the plasma concentration-time profiles	Selected time points during the first 28-day treatment cycle
Secondary	Pharmacokinetic parameters:T1/2	The terminal half-life of T-1301 derived from the plasma concentration-time profiles.	Selected time points during the first 28-day treatment cycle
Secondary	Objective response rate (ORR)	To assess preliminary anti-tumor activity with ORR according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1	At least 56 days
