About this study

Official title: A Multicenter, Single-Arm, Phase II Trial of Neoadjuvant Docetaxel and Cisplatin Combined With Dual Immunotherapy for Locally Advanced Sinonasal Carcinoma (PANDA Study)

The main objective of this prospective study is to evaluate the effectiveness and safety of a novel neoadjuvant therapy for patients with locally advanced sinonasal carcinoma (SNC). The treatment consists of the standard TP chemotherapy regimen (docetaxel and cisplatin) combined with dual immunotherapy (sintilimab and ipilimumab N01) administered before surgery. Researchers aim to determine the major pathological response (MPR) rate and long-term survival outcomes, while also exploring if this combination treatment approach can help better preserve critical facial and organ functions for SNC patients.

Read the detailed description

Currently, there is a lack of prospective phase II/III clinical evidence to guide the optimal treatment of locally advanced sinonasal carcinoma (SNC). Based on current clinical guidelines for head and neck squamous cell carcinoma (HNSCC), the investigators hypothesize that the combination of TP chemotherapy with dual immune checkpoint inhibitors (targeting PD-1 and CTLA-4) could significantly improve the major pathological response (MPR) and achieve superior organ function preservation in patients with locally advanced SNC.

By evaluating the TP regimen combined with sintilimab and ipilimumab N01, this trial seeks to validate the feasibility of organ function preservation under this therapeutic modality. If successful, this treatment strategy will establish a novel precision treatment paradigm that effectively balances tumor control with organ function preservation, laying a solid foundation for subsequent phase III randomized controlled trials.

What is being measured

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

  1. Major Pathological Response Rate(MPR)

    Defined as the percentage of participants whose resected tumor specimens show ≤10% viable tumor cells upon microscopic examination following neoadjuvant therapy.

    Measured: From enrollment to the end of treatment at 9 weeks

Secondary outcomes (10)
  1. Objective Response Rate (ORR)

    Defined as the proportion of patients who achieve a Complete Response (CR) or Partial Response (PR) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.

    Measured: Up to 2 years

  2. 2-Year Overall Survival (OS) Rate

    Defined as the percentage of participants who are alive 2 years after the initiation of treatment.

    Measured: 2 years from the start of treatment

  3. Median Overall Survival (mOS)

    Defined as the time from the start of treatment to death from any cause in 50% of the evaluated patients.

    Measured: Up to 2 years

  4. 2-Year Progression-Free Survival (PFS) Rate

    Defined as the percentage of participants who remain alive and free of disease recurrence, new metastasis, or disease progression 2 years after the completion of the last treatment.

    Measured: 2 years from the end of the last treatment

  5. Median Progression-Free Survival (mPFS)

    Defined as the time from the start of treatment until disease progression or death in 50% of the evaluable patients.

    Measured: Up to 2 years

  6. Duration of Response (DoR)

    Evaluated per RECIST v1.1.

    Measured: From the first documented CR or PR until the first documented tumor progression or death from any cause, assessed up to 2 years

  7. Disease Control Rate (DCR)

    Defined as the percentage of patients who achieve a Complete Response (CR), Partial Response (PR), or Stable Disease (SD) following treatment.

    Measured: Up to 2 years

  8. R0 Resection Rate

    Defined as the percentage of patients achieving a complete tumor resection with microscopically negative margins.

    Measured: At the time of surgery (assessed up to 4 weeks after completion of neoadjuvant therapy)

  9. Organ Functional Preservation Rate (OFPR)

    Defined as the percentage of living patients at 2 years post-treatment who do not require salvage radical surgery and successfully preserve major physiological functions. Patients must meet all 4 conditions:

    Maxilla \& Oral: No total maxillectomy (limited/scaffold-preserving excision allowed); no permanent tube feeding; intelligible speech; no severe trismus (mouth opening >2.5cm).

    Orbit \& Vision: No enucleation/orbital exenteration; ipsilateral vision better than light perception (≥0.05); no intractable diplopia, severely restricted eye movement, or eyelid dysfunction causing exposure keratitis.

    Skull Base \& Neurological: No massive cranial/dural defect from extensive resection; no persistent CSF leak; no severe treatment-induced CNS complications.

    Appearance: No obvious facial collapse or disfigurement; adequate subjective satisfaction (FACE-Q scale); no external facial prosthesis required.

    Measured: At 2 years post-treatment

  10. Change in Quality of Life Scores (QOL)

    The psychological state and overall quality of life of the patients will be evaluated using the QOL-V30 questionnaire. Higher scores generally represent a higher quality of life or level of functioning.

    Measured: Baseline and up to 2 years

A Phase 2 study testing Neoadjuvant Chemo-Immunotherapy in people with Locally Advanced Sinonasal Carcinoma, run by Sun Yat-sen University.

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 10 inclusion and 20 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: opening soon, as of the sponsor's last update on 25 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

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 Kaiyue Mao (86-020-87342926, maokaiyue@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Major Pathological Response Rate(MPR) (time frame: From enrollment to the end of treatment at 9 weeks). 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 25 Jun 2026; AzTrials last refreshed its copy on 7 Nov 2026.
