NCT05879250

Brief Summary

This phase II trial tests how well the combination of WP1066 and radiation therapy works in treating newly diagnosed glioblastoma. Glioblastoma is difficult to treat effectively because the cells within the tumor vary widely and are controlled by factors within and around the tumor, requiring multiple approaches to treat the tumor. The study drug WP1066 targets a specific pathway, known as STAT3, which is responsible for promoting tumor growth and causing the body's immune system to avoid attacking the tumor. Radiation therapy prevents glioblastoma from growing. Giving WP1066 with radiation therapy may prevent glioblastoma from growing and prolong survival.

Outcome Measures

Primary Outcomes (2)

  • Progression-Free Survival (PFS) (Cohort 1)

    For PFS analysis, disease progression is defined as progressive disease (PD) per Response Assessment in Neuro-Oncology (RANO) criteria Will be summarized using the Kaplan-Meier method.

    From subject registration to the earlier of the day of first documented disease progression or death from any cause, assessed up to 36 months post-registration

  • Tumor microenvironment activation and cluster interactions (Cohort 2)

    Up to 36 months post-registration

Secondary Outcomes (5)

  • Overall Survival (OS)

    From the date of initial diagnosis until death from any cause, assessed up to 36 months

  • Overall Response Rate (ORR)

    Up to 36 months post-registration

  • Duration of response (DOR)

    Up to 36 months post-registration

  • Frequency of adverse events

    Up to 36 months post-registration

  • Time to response/progression

    Up to 36 months post-registration

Study Arms (2)

Cohort I (WP1066, radiation)

EXPERIMENTAL

Patients whose tumor was completely removed at the time of initial surgery receive WP1066 PO for 6 weeks during routine radiation therapy, and then for twelve 28-day cycles on study. Patients also undergo MRI and collection of blood samples throughout the trial.

Procedure: Biospecimen CollectionProcedure: Magnetic Resonance ImagingRadiation: Radiation TherapyDrug: STAT3 Inhibitor WP1066

Cohort II (WP1066, radiation, surgery)

EXPERIMENTAL

Patients whose tumor was not fully removed at the time of initial surgery receive WP1066 PO for 6 weeks during routine radiation therapy on study. Patients may then undergo possible surgery or open biopsy if eligible, followed by twelve 28-day cycles of WP1066 PO on study. Patients also undergo MRI and collection of blood samples throughout the trial.
