About this study
This study is a prospective, single-arm clinical trial with a dose-reduction design, which is expected to enrol 18 patients with locally advanced rectal cancer with pMMR status. The aim is to investigate the safety and efficacy of neoadjuvant chemoradiotherapy combined with sintilimab and suvecitib.
Patients will receive long-course chemoradiotherapy (concurrent capecitabine, 1000 mg/m², twice daily, days 1-14, Q3W, 2 cycles; sintilimab, 200 mg, d1, IV drip, Q3W, 2 cycles), followed by 6 cycles of the Capeox regimen in combination with sintilimab and suvecitib, namely oxaliplatin 130 mg/m², d1, IV infusion, every 3 weeks; and capecitabine 1,000 mg/m², twice daily, days 1-14, every 3 weeks; sintilimab, 200 mg, Day 1, IV drip, every 3 weeks; suvectitumab (anti-angiogenic agent), 2.0/1.5/1.0 mg/kg, Day 1, IV drip, every 3 weeks. A total of 8 cycles of sintilimab and 6 cycles of suvectitumab were administered during the neoadjuvant treatment period.
If, following completion of neoadjuvant therapy, the subject has not achieved cCR/near-cCR status, TME surgery or other therapeutic surgery shall be performed; the interval between the final dose of suvectitumab and surgery should be ≥6 weeks. If cCR/near-cCR status is achieved, watchful waiting or other treatment options shall be discussed with the patient. The adjuvant treatment regimen following surgery shall be determined by the investigator based on the patient's pathological results.

This study is a prospective, single-arm clinical trial with a dose-reduction design, which is expected to enrol 18 patients with locally advanced rectal cancer with pMMR status. The aim is to investigate the safety and efficacy of neoadjuvant chemoradiotherapy combined with sintilimab and suvecitib.
Patients will receive long-course chemoradiotherapy (concurrent capecitabine, 1000 mg/m², twice daily, days 1-14, Q3W, 2 cycles; sintilimab, 200 mg, d1, IV drip, Q3W, 2 cycles), followed by 6 cycles of the Capeox regimen in combination with sintilimab and suvecitib, namely oxaliplatin 130 mg/m², d1, IV infusion, every 3 weeks; and capecitabine 1,000 mg/m², twice daily, days 1-14, every 3 weeks; sintilimab, 200 mg, Day 1, IV drip, every 3 weeks; suvectitumab (anti-angiogenic agent), 2.0/1.5/1.0 mg/kg, Day 1, IV drip, every 3 weeks. A total of 8 cycles of sintilimab and 6 cycles of suvectitumab were administered during the neoadjuvant treatment period.
According to data from previous studies, the recommended dose of suvecitib in combination with a PD-L1 inhibitor and FOLFIRI chemotherapy for second-line treatment of advanced MSS colorectal cancer is 2 mg/kg every 2 weeks. However, given that the neoadjuvant treatment regimen in this clinical trial involves multiple modalities-including chemotherapy, radiotherapy, targeted therapy and immunotherapy-and the intensity is high with unknown toxicity profiles, a dose-escalation design was adopted in the early phase of this clinical study.
Specifically, six patients will initially be enrolled to receive suvicitabant at 2 mg/kg to assess safety. Following completion of neoadjuvant therapy in the third patient, if two or more patients develop Grade 4 acute radiation-induced rectal injury, the dose of suvicitabant will be reduced to 1.5 mg/kg for re-evaluation. If two or more patients still develop Grade 4 acute radiation-induced rectal injury, the dose will be further reduced to 1 mg/kg for re-evaluation.
If 1 or fewer patients develop Grade 4 acute radiation-induced rectal injury, the sample size for this cohort will be expanded to 18 patients. Following completion of neoadjuvant therapy, if a subject has not achieved cCR/near-cCR status, they will undergo TME or other therapeutic surgery; the interval between the final dose of suvecitib and surgery must be ≥6 weeks. If cCR/near-cCR status is achieved, watchful waiting or other treatment options will be discussed with the patient. Postoperatively, the investigator shall determine the adjuvant treatment regimen based on the patient's pathological results.

Scores will be linearly transformed to a 0-100 scale. For the global health status/quality-of-life scale, a higher score represents a better level of global health status and quality of life. Changes from baseline will be evaluated during follow-up.
Measured: From date of randomization , assessed up to 60 months.
Incidence of Surgical Complications
Measured: the surgical complications were assessed up to 1 year from the surgery.
Distant Metastasis Rate
Measured: within 3 years of randomization

Measured: within 3 years of randomization
5-Year Overall Survival Rate
Measured: The time from randomization to death from any cause,assessed up to 60 months.
3-Year Event-Free Survival Rate
Measured: 3 years after randomization

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Drug：sintilimab, Drug：Capecitabine and Drug：Suvemcitug in people with Rectal Cancer, run by Sun Yat-sen University 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 13 inclusion and 18 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 19 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 Xiao weiwei (8613710390520, xiaoww@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Serious Adverse Effects of Neoadjuvant Therapy (time frame: During neoadjuvant therapy). 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 19 Aug 2026; AzTrials last refreshed its copy on 8 Nov 2026.
