Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a first-in-human phase I/II study to examine the safety, tolerability and preliminary efficacy of VLS-1488 in subjects with advanced cancers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Dose Escalation: Dose Escalation Cohorts

Subjects will be enrolled at various doses and/or schedules of VLS-1488. These Dose Escalation Cohorts will be utilized to identify the MTD and to select dose levels for Dose Expansion.

Group Type EXPERIMENTAL

VLS-1488

Intervention Type DRUG

VLS-1488 tablets will be given orally.

Dose Escalation: Backfill Cohorts

Additional subjects may be enrolled at any dose level that does not meet de-escalation or elimination rules per the BOIN design. These Backfill Cohorts will be utilized to build additional data to support selection of doses and/or tumor types for further study in Dose Expansion.

Group Type EXPERIMENTAL

VLS-1488

Intervention Type DRUG

VLS-1488 tablets will be given orally.

Dose Expansion: Exploration Cohorts

Subjects with a selected single tumor type will be randomized 1:1 into Exploration Cohorts at two or more dose levels of interest. A subset of subjects will have additional assessments to examine the potential for VLS-1488 to interact with other drugs and the effect of food on VLS-1488 absorption.

Group Type EXPERIMENTAL

VLS-1488

Intervention Type DRUG

VLS-1488 tablets will be given orally.

Dose Expansion: Development Cohorts

Subjects with other tumor types will be enrolled at a single dose level of interest. These Development Cohorts will be utilized to examine the preliminary efficacy of VLS-1488 in various tumor types.

Group Type EXPERIMENTAL

VLS-1488

Intervention Type DRUG

VLS-1488 tablets will be given orally.
