About this study

Official title: A Single -Centers, Randomized, Open-label, Controlled Phase Ⅱ Clinical Trial of Short-course Radiotherapy Followed by Tislelizumab + CapeOX in the Treatment for Locally Advanced Rectal Cancer

This study is a single-center, prospective, open-label, randomized controlled clinical study, and the purpose of this study was to compare the pathological complete response rate (PCR) of patients with locally advanced rectal cancer treated with short-course radiotherapy sequential Tislelizumab combined with CapeOX (group A) versus short-course radiotherapy sequential CapeOX (group B). A total of 100 patients with locally advanced rectal cancer will be enrolled in the study. These patients were randomly assigned to the experimental group (group A) and the control group (group B) in a ratio of 1:1.

Read the detailed description

Baseline examnation: All enrolled patients in this study, in addition to routine laboratory and imaging examinations such as blood routine, blood biochemistry, serum tumor markers (Incl. CEA, CA-199, CA-724 β2-microglobulin, Ferroprotein), chest CT, abdominal and pelvic MRI, etc., were required to undergo KRAS, NRAS, BREF, PD-L1, MMR/MSS testings before SCRT, and blood lymphocyte subgroups were analyzed before SCRT, systemic therapy, and surgery.

Subjects in group A will be treated according to the following treatment plan:

Standard SCRT: A total radiation dose of 25 Gy was delivered in 5 fractions (from day 1 to 5)

Sequential treatment period: After resting for 3-7 days following completion of SCRT, patients were treated with 4 cycles of CapeOX (Oxaliplatin 130 mg/m2 intravenously, day 1; Capecitabine 1000 mg/m2, Bid,days 1-14) and an additional intravenous infusion of 200mg Tislelizumab on the first day of each cycle of CapeOX.

Surgery: After 3 weeks of the completion of neoadjuvant therapy, the TME surgery was performed.

Postoperative adjuvant chemotherapy:Whether postoperative chemotherapy was implemented mainly depended on the patient's wishes, and 2 cycles of CapeOX with or without Tislelizumab will be undergone to these willing cases.

Subjects in group B will be treated according to the following treatment plan:

Standard SCRT: A total radiation dose of 25 Gy was delivered in 5 fractions (from day 1 to 5)

Sequential treatment period: After resting for 3-7 days following completion of SCRT, patients were treated with 4 cycles of CapeOX (Oxaliplatin 130 mg/m2 intravenously, day 1; Capecitabine 1000 mg/m2, Bid,days 1-14).

Surgery: After 3 weeks of the completion of neoadjuvant therapy, the TME surgery was performed.

Postoperative adjuvant chemotherapy:Whether postoperative chemotherapy was implemented mainly depended on the patient's wishes, and 2 cycles of CapeOX will be undergone to these willing cases.

Endpoint: The primary endpoint was pCR rate. Secondary endpoints included MPR (TRG0+TRG1), 3-year PFS, 3-year OS, and treatment safety.

Follow-up records during treatment: For the duration of operation, the time required to complete the TME surgery and the amount of blood loss were recorded, and the impact of neoadjuvant therapy on the operation was observed. During the SCRT process, and the period of resting after SCRT, of the entire preoperative systemic treatment, of the resting after TME surgery, of the postoperative chemotherapy (these willing cases), the occurrence of adverse events (AE) of participants were closely monitored and actively responded.

What is being measured

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

  1. Pathological complete response rate

    Pathological complete response rate was defined as the absence of viable tumour cells in the resected primary tumour specimen and all sampled regional lymph nodes (ypT0N0)

    Measured: 1 week after surgery

Secondary outcomes (4)
  1. major pathologic response (TRG0+TRG1)

    TRG 0 indicates no remaining viable cancer cells (complete response); TRG 1 indicates a single cell or small groups of cancer cells (moderate response)

    Measured: 1 week after surgery

  2. 3-year PFS

    PFS refers to the time from randomization to tumor progresses or death from any cause

    Measured: 3 years from randomization

  3. 3-year OS

    OS refers to the time from randomization to death from any cause

    Measured: 3 years from randomization

  4. Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]

    Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] during treatment, including chemoradiotherapy, immunology, sugery

    Measured: through study completion, an average of 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tislelizumab, Short-course radiotherapy and Capecitabine+Oxaliplatin in people with Locally Advanced Rectal Cancer, run by Hebei Medical University Fourth 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 20 inclusion and 8 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: finished, as of the sponsor's last update on 22 Aug 2024. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathological complete response rate (time frame: 1 week after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05086627, which also lists 1 linked publication.

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 22 Aug 2024.
