About this study

Official title: Non-Randomized Phase 2 Trial of Three Schedules of CUE-101 Administered Before Surgery or Definitive Chemoradiation Therapy in HLA-A*0201 Positive Patients With Locally Advanced, HPV16-Positive Oropharyngeal Squamous-Cell Carcinoma

This is a phase 2 trial to assess the safety and tolerability of three schedules of CUE-101 administered in the neoadjuvant phase before standard of care (SOC) therapy to treatment naïve, HLA-A*0201 positive patients with newly diagnosed, locally advanced HPV16+ oropharyngeal squamous-cell carcinoma (OPSCC). This is an exploratory trial of a limited sample size to confirm safety and to assess for pharmacodynamic signals of efficacy in each of three schedules of CUE-101. Safety assessments will be performed at baseline and after CUE-101 administration. To assess for efficacy, peripheral blood and tumor samples will be collected at baseline and after CUE-101 administration. Following CUE-101, patients will proceed with SOC therapy, as prescribed by the treating physician.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of treatment-related adverse events

    Measured: From start of treatment through 12 months after the completion of standard of care treatment (estimated to be 15 months)

  3. Treatment-related delays in start of standard of care therapy

    -Defined as >7 days of treatment-related delay from the planned date of surgery or initiation of definitive-chemoradiation therapy.

    Measured: From start of treatment through start of standard of care therapy (estimated to be 2 weeks)

Secondary outcomes (9)
  1. Pathological tumor response

    • Defined as rates of major and complete pathological response
    • A major pathologic response (mPR) will be defined as ≤ 10% residual viable tumor within the tumor sample collected after administration of CUE-101. A complete pathologic response (cPR) will be defined as no invasive cancer in the tumor sample collected. For surgical patients, the tumor sample will include the primary tumor specimen and all sampled regional lymph nodes at the time of resection. For def-chemoradiation therapy patients, the tumor sample will comprise the biopsy(s) submitted. Pathologic tumor response will be stratified based on if the patients underwent surgery or post-CUE-101 biopsy only.

    Measured: At the time of surgery or biopsy (Day 1 - approximately 7-14 days after start of CUE-101 treatment)

  2. Objective response rate (ORR)

    • Proportion of patients with a complete response + partial response
    • Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Disappearance of all non-target lesions and normalization of tumor marker level.
    • Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.

    Measured: Prior to surgery/definitive chemoradiation treatment (Day 1 - approximately 7-14 after start of CUE-101 treatment)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CUE-101 in people with Oropharyngeal Squamous Cell Carcinoma, run by Washington University School of Medicine at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 18 inclusion and 30 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 20 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jesse Zaretsky, M.D. (314-747-8244, jzaretsky@wustl.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of treatment-related adverse events (time frame: From start of treatment through 12 months after the completion of standard of care treatment (estimated to be 15 months)). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jul 2026.
