WSD0922-FU for the Treatment of Glioblastoma, Anaplastic Astrocytoma, or Non-small Cell Lung Cancer With Central Nervous System Metastases

March 26, 2026 updated by: Mayo Clinic

Phase I Study to Evaluate Safety, Tolerability, Pharmacokinetics and Anti-Tumor Activity of WSD0922-FU

This phase I trial studies the side effects and best dose of WSD0922-FU for the treatment of glioblastoma, anaplastic astrocytoma, or non-small cell lung cancer that has spread to the central nervous system (central nervous system metastases). WSD0922-FU is a targeted treatment which blocks the EGFR protein - a strategy that has led to a lot of benefit in patients with many different cancers. WSD0922-FU may also be able to get into cancers in the brain and spinal cord and help patients with brain and spinal cord cancers.

Detailed Description

PRIMARY OBJECTIVE:

I. To determine the maximum tolerated dose (MTD) and/or the recommended phase 2 dose (RP2D) of EGFR/EGFRvIII inhibitor WSD0922-FU (WSD0922-FU) in subjects with recurrent glioblastoma, IDH wildtype (GBM), anaplastic astrocytoma, IDH wildtype (AA) and central nervous system (CNS) metastases of non-small cell lung cancer (NSCLC).

SECONDARY OBJECTIVES:

I. To evaluate the incidence of treatment-emergent adverse events (TEAEs) related to WSD0922-FU.

II. To assess anti-tumor activity: intracranial and extracranial overall response rate (ORR), and change in tumor size compared with baseline according to Response Assessment in Neuro-Oncology (RANO) criteria for GBM/AA and Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 for NSCLC.

III. To assess anti-tumor activity: intracranial and extracranial disease control rate (DCR) and change in tumor size compared with baseline according to RANO criteria for GBM/AA and RECIST 1.1 for NSCLC.

IV. To assess anti-tumor activity: intracranial and extracranial duration of response (DOR) and change in tumor size compared with baseline according to RANO criteria for GBM/AA and RECIST 1.1 for NSCLC.

V. To assess anti-tumor activity: intracranial and extracranial progression-free survival (PFS) and change in tumor size compared with baseline according to RANO criteria for GBM/AA and RECIST 1.1 for NSCLC.

EXPLORATORY/CORRELATIVE RESEARCH OBJECTIVES:

I. To investigate the presence and/or identity of the drug metabolites of WSD0922-FU, and the concentrations of these in the plasma, cerebrospinal fluid (CSF), and tumor.

II. To assess plasma concentration of WSD0922-FU and metabolite SN16110801P1 and pharmacokinetics (PK) parameters after single and multiple doses of WSD0922-FU.

III. To assess the brain tumor pharmacokinetics of WSD0922-FU and SN16110801P1 after a single dose of WSD0922-FU (Dose Expansion - Brain tumor penetration [BTP] cohort only).

IV. To assess cerebrospinal fluid (CSF) concentration of WSD0922-FU and SN16110801P1 after multiple doses of WSD0922-FU (Dose Expansion - NSCLC cohort only).

V. To explore the impact of tumor markers (e.g. MGMT promoter methylation, EGFR mutation [including EGFR vIII], PTEN deletion, TP53 mutation, etc.) on clinical parameters associated with WSD0922-FU treatment.

VI. To evaluate and measure pharmacodynamic biomarkers of inhibition of EGFR and downstream signals in tumor samples after a single dose of WSD0922-FU (Dose Expansion Cohort - BTP cohort only).

VII. To evaluate the effect of food on the pharmacokinetics of single dose of WSD0922-FU in plasma (Dose Expansion - GBM/AA cohort only).

OUTLINE: This is a dose-escalation study.

DOSE ESCALATION: Patients receive WSD0922-FU orally (PO) once daily (QD) or twice daily (BID) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT), magnetic resonance imaging (MRI), and collection of blood samples on study. Patients with NSCLC with leptomeningeal metastases (LM) also undergo collection of CSF samples on study.

DOSE EXPANSION: Patients are assigned to 1 of 3 cohorts.

COHORT I: Patients with GBM/AA receive WSD0922-FU PO on days 1 and 4 of cycle 0. Patients then receive WSD0922-FU PO BID on days 1-28 of subsequent cycles. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI during screening and on study, as well as blood sample collection on study. Patients may undergo additional optional blood sample collection on study.

COHORT II: Patients with BTP receive a single dose of WSD0922-FU prior to surgery. Patients then undergo surgical resection of brain tumor. After surgery, patients receive WSD0922-FU PO BID on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI during screening and on study, as well as blood sample collection on study.

COHORT III: Patients with NSCLC receive WSD0922-FU PO BID on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI and CT during screening and on study, as well as blood sample collection on study. Patients with LM also undergo collection of CSF samples on study. Patients may also undergo optional blood sample collection on study.

After completion of study treatment, patients are followed up at 4-6 weeks, then every 2 months until progressive disease, at progressive disease, and then every 3 months after progressive disease for up to 5 years.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Recommended phase 2 dose

Up to 28 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Duration of response (DOR)
Time Frame: From the first occurrence of a PR (or better) and progression, assessed up to 5 years
Duration of response is defined as the number of days between a patient's first occurrence of a PR (or better) and progression. If a patient goes off study prior to progression (for another reason) then they will be censored at that time. A time to event analysis will be performed utilizing the Kaplan-Meier method which will yield a median DOR.
From the first occurrence of a PR (or better) and progression, assessed up to 5 years
Progression Free Survival (PFS)
Time Frame: From study entry to disease progression, assessed up to 5 years
A patient's progression free survival time is the number of days between study entry and disease progression. These data will be analyzed utilizing the Kaplan-Meier method which will yield a median PFS time.
From study entry to disease progression, assessed up to 5 years
Overall response rate
Time Frame: Up to 5 years
The overall response rate will be defined as the number of patients with a partial response (PR) or complete response (CR) that is confirmed in consecutive evaluations (at least 8 weeks apart) divided by the total number of evaluable patients. A 95% confidence interval will also be constructed using the properties of the binomial distribution.
Up to 5 years
Incidence of adverse events
Time Frame: Up to 4-6 weeks after study completion
Assessed using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0
Up to 4-6 weeks after study completion
