Outcome Measures

Primary Outcomes (1)

  • Dose Limiting Toxicity (DLT)

    Dose-limiting toxicity (DLT) is defined as any treatment-related Grade 3 or higher adverse event, or other clinically significant toxicity occurring during the first cycle (4 weeks), that meets the protocol-defined criteria for dose limitation, based on the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version \[5.0\].

    4 weeks

Secondary Outcomes (11)

  • Pharmacokinetics (PK): Cmax

    Cycle 1, Days 1-2 (cycle is 28 days)

  • Pharmacokinetics (PK): Tmax

    Cycle 1, Days 1-2 (cycle is 28 days)

  • Pharmacokinetics (PK): AUC

Study Arms (1)

AST-201

EXPERIMENTAL

Participants receive AST-201 administered intravenously according to the study dosing schedule.

Drug: AST-201

Interventions

AST-201 is administered intravenously on Days 1, 8, and 15 of each 28-day cycle, followed by a one-week rest period. Dosing is repeated until DLT or disease progression is occurred.
