About this study

Official title: A Single-Arm, Prospective Clinical Study of Sintilimab Combined With Disitamab Vedotin as Neoadjuvant Therapy for Locally Advanced Eyelid Sebaceous Gland Carcinoma

The goal of this clinical trial is to evaluate the efficacy and safety of neoadjuvant therapy with Sintilimab combined with Disitamab Vedotin in patients with locally advanced, resectable or potentially resectable sebaceous gland carcinoma. The main questions it aims to answer are: What is the major pathological response (MPR) rate after the neoadjuvant therapy? What are the pathological complete response (pCR) rate, clinical objective response rate (ORR), disease control rate (DCR), safety profiles, and 1-year disease-free survival (DFS) of this regimen? Participants will:Receive neoadjuvant therapy consisting of Sintilimab (200 mg, IV, Day 1) and Disitamab Vedotin (2.5 mg/kg, IV, Day 1) every 3 weeks for a total of 2 cycles. Undergo radical surgery after the completion of the neoadjuvant treatment phase. Receive postoperative adjuvant therapy after surgery, which includes uniform Sintilimab monotherapy maintenance (200 mg, IV, Q3W) for up to 1 year, and may receive risk-stratified local interventions (such as local radiotherapy or repeat wide excision) depending on the pathological risk factors.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SintilimabDrug

    Sintilimab is administered at 200 mg intravenously on Day 1 of each 3-week cycle. In the neoadjuvant phase, it is given concurrently with Disitamab Vedotin for 2 cycles before radical surgery. In the adjuvant phase, post-surgery, it is administered as monotherapy maintenance for up to 1 year, or until intolerable toxicity or distant disease progression occurs.

  • disitamab vedotinDrug

    Disitamab Vedotin is administered at 2.5 mg/kg intravenously on Day 1 of each 3-week cycle. It is given exclusively during the neoadjuvant phase for a total of 2 cycles concurrently with Sintilimab prior to radical surgery.

Study groupRoleWhat they receive
Sintilimab Combined with Disitamab VedotinExperimentalParticipants will receive neoadjuvant therapy consisting of intravenous sintilimab (200 mg) and disitamab vedotin (2.5 mg/kg, rounded to the nearest whole vial) on Day 1 of each 3-week cycle, for a total of 2 cycles. Following the neoadjuvant phase, patients will undergo radical surgical resection. Post-surgery, patients will receive adjuvant therapy comprising single-agent sintilimab (200 mg, intravenous, Q3W), continuing for 1 year or until unacceptable toxicity or disease progression occurs.
Receives: Drug: Sintilimab; Drug: disitamab vedotin

What is being measured

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

  1. Major Pathologic Response (MPR) Rate

    Among participants who undergo surgery, major pathologic response (MPR) is defined according to immune-related pathologic response criteria (irPRC) as ≤10% residual viable tumor cells in the tumor bed (%RVT ≤10%), regardless of whether residual viable tumor cells are present in lymph nodes.

    Measured: At the time of surgery, after completion of neoadjuvant treatment

Secondary outcomes (7)
  1. Pathologic Complete Response (pCR) Rate

    Among participants who undergo surgery, pathologic complete response (pCR) is defined according to immune-related pathologic response criteria (irPR) as no residual viable tumor cells in the tumor bed or resected lymph nodes (%RVT = 0).

    Measured: At the time of surgery, after completion of neoadjuvant treatment

  2. Objective Response Rate (ORR)

    Objective response rate (ORR) is defined as the proportion of participants with a complete response (CR) or partial response (PR), as assessed according to RECIST version 1.1

    Measured: From baseline to pre-operative tumor assessment following 2 cycles of neoadjuvant therapy (up to 9 weeks)

  3. Disease Control Rate (DCR)

    Disease control rate (DCR) is defined as the proportion of participants with a complete response (CR), partial response (PR), or stable disease (SD), as assessed according to RECIST version 1.1

    Measured: From baseline to pre-operative tumor assessment following 2 cycles of neoadjuvant therapy (up to 9 weeks).

  4. Adverse Events (AEs)

    Adverse events (AEs) will be assessed according to CTCAE version 5.0, and all treatment-related adverse events will be reported to evaluate the safety of treatment.

    Measured: From first dose through 30 days after the last dose of neoadjuvant treatment

  5. Surgery Delay Rate

    Surgery delay rate is defined as the proportion of participants whose interval between the completion of the 2nd cycle of neoadjuvant therapy and radical surgery exceeds 4 weeks (interval > 4 weeks) due to neoadjuvant therapy-related toxicities.

    Measured: From completion of Cycle 2 of neoadjuvant therapy (each cycle is 21 days) to the date of radical surgery.

  6. 1-Year Disease-Free Survival (DFS) Rate

    1-Year disease-free survival (DFS) rate is defined as the proportion of participants who remain alive and free of any tumor recurrence (local or regional) or distant metastasis at 1 year following radical surgery

    Measured: From the date of radical surgery up to 1 year.

  7. R0 Resection Rate

    The proportion of participants who achieve R0 resection among those undergoing definitive surgery.

    Measured: At the time of surgery, after completion of neoadjuvant treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Sintilimab and disitamab vedotin in people with Sebaceous Gland Carcinoma, run by West China Hospital at 1 site in China.

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 1 inclusion and 1 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 3 Aug 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 China. 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 Huaju yang PhD (+8613340239461, yhjyanghuaju@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Major Pathologic Response (MPR) Rate (time frame: At the time of surgery, after completion of neoadjuvant treatment). 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 3 Aug 2026.
