This a first-in-human phase I/II study designed to assess the safety, tolerability and
preliminary efficacy of VLS-1488 monotherapy and consists of two parts: Dose Escalation
and Dose Expansion.
Dose Escalation will examine the safety and tolerability of VLS-1488 in different solid
tumor types at various dose levels through a series of Dose Escalation and Backfill
Cohorts to identify the Maximum Tolerated Dose (MTD) and to select dose levels for Dose
Expansion. The criteria for dose (de-)escalation will be based on a Bayesian Optimal
Interval (BOIN) design.
Dose Expansion will examine the safety, tolerability, Drug Drug Interaction (DDI) risk,
Food Effect (FE) and preliminary efficacy of VLS-1488 in different tumor types and/or
dose levels of interest through various expansion cohorts.
VLS-1488 will be given orally in 28-day cycles. Dosing will be continued until disease
progression, unacceptable toxicity, withdrawal of consent, or other stopping criteria are
met.
