A Dose Escalation and Dose Expansion Clinical Study of STI-7349 in Subjects With Advanced Solid Tumors
Study Details
Study Description
Brief Summary
This is a first-in-human, Phase Ⅰ, open-label, 2-period dose escalation and expansion study of STI-7349 administered intravenously to subjects with advanced solid tumors:
-
Period I is divided into two parts: Dose escalation for STI-7349 alone (1A) and dose expansion for STI-7349 alone (1B). In Part 1A, a rapid titration approach and traditional 3 + 3 trial design will be used to assess the safety, dose-limiting toxicities (DLTs), maximum tolerated dose (MTD), PK/biomarker profile, and to determine the recommended Phase 2 dose (RP2D) of STI-7349 alone; in Part 1B, an expansion study of STI-7349 alone will be conducted in target tumor types that may potentially benefit to assess the safety and preliminary efficacy of STI-7349 alone.
-
Period Ⅱ is divided into two parts: Dose escalation for STI-7349 in combination with Pembrolizumab (2A) and dose expansion for STI-7349 in combination with Pembrolizumab (2B). In Part 2A, a dose escalation study of STI-7349 in combination with Pembrolizumab is planned to be conducted using ½ RP2D of STI-7349 alone as the starting dose, which will use a traditional 3 + 3 trial design to assess the safety, DLTs, MTD, PK/biomarker profile of STI-7349 in combination with Pembrolizumab, and to determine the RP2D of STI-7349 in combination with Pembrolizumab; in Part 2B, an expansion study of STI-7349 in combination with Pembrolizumab will be conducted in target tumor types that may potentially benefit to assess the safety and preliminary efficacy of the combination.

Detailed Description
Period I: Dose escalation of STI-7349 alone (1A) According to preclinical test data, 1 mg is the preliminary dose and an accelerated titration test design is used. The subsequent starting dose is designed to be 3 mg, with 100%, 100%, 50%, and 33.3% dose escalation in reference to the modified Fibonacci method, and the six dose groups initially set for STI-7349 dose escalation are 1 mg, 3 mg, 6 mg, 12 mg, 18 mg, and 24 mg, respectively, if no adverse events specified in the accelerated titration method below occurred. Subjects who pass screening will be sequentially enrolled into 6 dose groups from low to high dose in order.
Subjects in all dose groups will receive 21 days per dosing cycle and Day 1 of each cycle will be the dosing day.
Part 1A of this trial will use rapid titration and a traditional 3 + 3 trial design.
Period I: Dose expansion of STI-7349 alone (1B) Based on data from the 1A escalation period, target tumor types with potential benefit are selected, and subjects are expanded to 20 to 30 at the RP2D of STI-7349 alone to conduct an expansion study of STI-7349 alone to further assess the safety and preliminary efficacy of the RP2D of STI-7349 alone. STI-7349 will be administered at the same frequency as that in Part 1A and continued until the maximum 2-year dosing period, disease progression/relapse, death, intolerable toxicity, inability of the subject to benefit from study treatment as judged by the investigator, withdrawal from clinical study treatment by the subject or his/her legal representative, loss to follow-up, or completion of the entire study, whichever comes first.
Period II: Dose escalation for STI-7349 in combination with Pembrolizumab (2A) A dose escalation study of STI-7349 in combination with Pembrolizumab is conducted in subjects with advanced solid tumors according to the RP2D of STI-7349 alone determined in Period I. ½ RP2D of STI-7349 alone is used as the starting dose for the dose escalation study of the combination, and since the expected RP2D dose is 24 mg, the starting dose for the combination is 12 mg. The approved standard therapeutic dose of Pembrolizumab is 200 mg IV. According to the results of Period I of the study, the three dose groups for the preliminary dose-escalation study of STI-7349 in combination with Pembrolizumab are 12 mg, 18 mg, and 24 mg. Subjects who pass screening will be sequentially enrolled into 3 dose groups from low to high dose in order.
Period II: Dose expansion for STI-7349 in combination with Pembrolizumab (2B) According to the data from the 2A escalation period, target tumor types with potential benefit are selected, and subjects are expanded to 20 to 30 at the RP2D of the combination to conduct a dose expansion study of STI-7349 in combination with Pembrolizumab to further assess the safety and preliminary efficacy of the RP2D of the combination. STI-7349 will be administered at the same frequency as that in Part 2A and continued until the maximum 2-year dosing period, disease progression/relapse, death, intolerable toxicity, inability of the subject to benefit from study treatment as judged by the investigator, withdrawal from clinical study treatment by the subject or his/her legal representative, loss to follow-up, or completion of the entire study, whichever comes first.
