NCT05098132

Brief Summary

This is a phase 1/2, multicenter, open-label study. The phase 1 portion is a dose escalation and expansion study of STK-012 as monotherapy and in combination therapy in patients with selected advanced solid tumors. The phase 2 portion is a randomized study of STK-012 in combination with standard of care (SoC) pembrolizumab, pemetrexed, and carboplatin versus SoC, in patients with first line, PD-L1 negative, non-squamous, non-small cell lung cancer.

Outcome Measures

Primary Outcomes (8)

  • Phase 1a: Treatment emergent adverse events (TEAEs)

    Incidence of TEAEs in participants with select advanced solid tumors

    From 1st dose of study treatment through 90 days after last dose

  • Phase 1a: Serious adverse events (SAEs)

    Incidence of SAEs in participants with select advanced solid tumors

    From 1st dose of study treatment through 90 days after last dose

  • Phase 1a: Dose limiting toxicities (DLTs)

    Incidence of DLTs in participants with select advanced solid tumors

    Cycle 1, Days 1 through 21

  • Phase 1a: Deaths

    Incidence of death in participants with select advanced solid tumors

    From 1st dose of study treatment until death, up to 4 years

  • Phase 1b: TEAEs at the RP2D

    Incidence of TEAEs at the recommended phase 2 dose (RP2D) in participants with select advanced solid tumors

    From 1st dose of study treatment through 90 days after last dose

  • Phase 1b: SAEs at the RP2D

    Incidence of SAEs at the RP2D in participants with select advanced solid tumors

    From 1st dose of study treatment through 90 days after last dose

  • Phase 1b: Deaths at the RP2D

    Incidence of death at the RP2D in participants with select advanced solid tumors

    From 1st dose of study treatment until death, up to 4 years

  • Phase 2: Overall response rate (ORR) in Arm A versus Arm C

    To compare the ORR in 1L PD-L1 negative NSQ NSCLC subjects treated with STK-012 2.25 mg + SoC vs. SoC (Arms A vs. C). ORR is the proportion of subjects with confirmed complete response (CR) or confirmed partial response (PR) per BICR.

    From randomization until disease progression or death, or the last evaluable assessment in the absence of progression, up to 4 years

Secondary Outcomes (16)

  • Phase 1: ORR

    From enrollment until disease progression or death, or the last evaluable assessment in the absence of progression, up to 4 years

  • Phase 1: Progression free survival (PFS)

    From enrollment until first documentation of disease progression per investigator assessment or death due to any cause, whichever occurs first, up to 4 years

  • Phase 1: Overall survival (OS)

    From enrollment until death due to any cause, up to 4 years

  • Phase 1/2: STK-012 ADAs

    From screening through 30 days after last dose of STK-012

  • Phase 1/2: AUC of STK-012

    From screening through 30 days after last dose of STK-012

  • +11 more secondary outcomes
