    Dose escalation cohorts are monitored and assessed using the NCI Common Toxicity Criteria for Adverse Events, version 5.0.

    Up to 21 days from the first dose

Secondary Outcomes (11)

  • Objective Response Rate (ORR)

    Through study completion, an average of 9 months

  • Disease Control Rate (DCR)

    Through study completion, an average of 9 months

  • Duration of Objective Response (DOR)

    Through study completion, an average of 9 months

  • Progression Free Survival (PFS)

    From first study drug administration until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months

  • Overall Survival (OS)

    From first study drug administration until the date of death from any cause, assessed up to 24 months

Study Arms (3)

Arm A: TT-00420 Tablet Monotherapy

EXPERIMENTAL

TT-00420 tablets will be administered once daily in 21-day cycles. Dose escalation will be guided by a 3+3 design in Phase Ib to determine the recommended phase 2 dose (RP2D).

Drug: TT-00420

Arm B: TT-00420 tablet in combination with Atezolizumab Injection (Tecentriq ®)

EXPERIMENTAL

TT-00420 tablets will be administered once daily in 21-day cycles. Atezolizumab(1200 mg/20 mL) will be administered intravenously on Day 1 of each 21-day cycle. Dose escalation will be guided by a 3+3 design in Phase Ib to determine the recommended phase 2 dose (RP2D).

Drug: TT-00420Drug: Combination Product: Atezolizumab

Arm C: TT-00420 tablet in combination with nab-paclitaxel (Abraxane®)

EXPERIMENTAL

TT-00420 tablets will be administered once daily in 21-day cycles. Nab-paclitaxel 125 mg/m\^2 will be administered intravenously on Day 1 and 8 of each 21-day cycle. Dose escalation will be guided by a 3+3 design in Phase Ib to determine the recommended phase 2 dose (RP2D).

Drug: TT-00420Drug: Combination Product: Nab-Paclitaxel

Interventions

TT-00420 tablet will be administered orally once daily per protocol defined schedule.

Arm A: TT-00420 Tablet MonotherapyArm B: TT-00420 tablet in combination with Atezolizumab Injection (Tecentriq ®)Arm C: TT-00420 tablet in combination with nab-paclitaxel (Abraxane®)

Atezolizumab would be administered via infusion on Day 1 of 21-day cycle

Arm B: TT-00420 tablet in combination with Atezolizumab Injection (Tecentriq ®)

Nab-Paclitaxel would be administered via infusion on Day 1 and 8 of 21-day cycle

Arm C: TT-00420 tablet in combination with nab-paclitaxel (Abraxane®)
