Brief Summary

This is a first-in-human, phase 1a/1b, multicenter, open-label, dose escalation study of STK-012 as monotherapy and in combination therapy in patients with selected advanced solid tumors.

Detailed Description

The phase 1a portion of the study is a dose escalation design to evaluate STK-012 as monotherapy and in combination therapy in patients with selected solid tumors. The phase 1b portion of the study includes dose expansions to evaluate STK-012 as monotherapy and in combination therapy at the candidate recommended phase 2 dose (RP2D) in selected solid tumor types.

Primary Outcome Measures
NameTimeMethod
Dose limiting toxicities (DLTs)1 cycle (21 days)

Incidence of adverse events (AEs) meeting protocol defined DLT criteria and determination of the maximum tolerated dose (MTD) and/or the RP2D of STK-012 as a single agent and in combination therapy

Adverse eventsFrom 1st dose of STK-012 through 90 days after last dose of STK-012

Assess the safety and tolerability of STK-012 as monotherapy and in combination therapy by review of AEs including treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), adverse events leading to treatment discontinuation, and adverse events resulting in death.

Secondary Outcome Measures
NameTimeMethod
Objective response rate (ORR)Up to 24 months

The ORR is defined as the proportion of patients with confirmed CR or confirmed PR, based on RECIST Version 1.1 after STK-012 administration as monotherapy and in combination therapy

Progression-free survival (PFS)Up to 24 months

PFS is defined as the time from the start of treatment with STK-012 until the first documentation of disease progression or death due to any cause, whichever occurs first after STK-012 administration as monotherapy and in combination therapy

Overall Survival (OS)Up to 24 months

Overall survival is defined as the time from the start of treatment with STK-012 until death due to any cause after STK-012 administration as monotherapy and in combination therapy

Area under the curve (AUC) of STK-012From 1st dose of STK-012 through 30 days after last dose of STK-012

The AUC of STK-012 will be measured at different timepoints after STK-012 administration as monotherapy and in combination therapy

Maximum concentration (Cmax) of STK-012From 1st dose of STK-012 through 30 days after last dose of STK-012

The Cmax of STK-012 will be measured at different timepoints after STK-012 administration as monotherapy and in combination therapy

Time of maximum concentration (Tmax) of STK-012From 1st dose of STK-012 through 30 days after last dose of STK-012

The Tmax of STK-012 will be measured at different timepoints after STK-012 administration as monotherapy and in combination therapy

Half-life (T1/2) of STK-012From 1st dose of STK-012 through 30 days after last dose of STK-012

The T1/2 of STK-012 will be measured at different timepoints after STK-012 administration as monotherapy and in combination therapy

ImmunogenicityFrom 1st dose of STK-012 through 30 days after last dose of STK-012

The immunogenicity of STK-012 will be assessed by summarizing the number of patients who develop detectable anti-drug antibodies (ADAs) at different timepoints after STK-012 administration as monotherapy and in combination therapy
