Patient-reported and clinical outcomes after Chidamide plus sintilimab (± bevacizumab) for MSS advanced colorectal cancer

Patient-reported Outcomes (PRO) and Treatment Outcomes of Chinese Patients With MSS-type Advanced Colorectal Cancer Who Received the Zidovudine Combination Regimen in the Real World: A Prospective, Multicenter, Observational Study Protocol

Observational West China Hospital · NCT07105631

This project will see how well Chidamide combined with sintilimab, with or without bevacizumab, is tolerated and reported by Chinese adults with MSS advanced colorectal cancer receiving it in routine care.

What this trial studies

This is a prospective real-world observational cohort enrolling adults with histologically confirmed MSS/pMMR advanced colorectal cancer treated with an HDAC inhibitor plus an immune checkpoint inhibitor regimen. Participants report symptoms and quality-of-life measures electronically while clinicians record safety events and treatment outcomes. The primary endpoint is safety events related to the combination regimen; secondary data include patient-reported outcomes and clinical effectiveness in routine practice. Enrollment and follow-up occur at West China Hospital, and no specific investigational treatment is assigned by the protocol.

Who should consider this trial

Good fit: Adults (age ≥18) with histologically confirmed advanced MSS/pMMR colorectal cancer whom their treating physician plans to treat with an HDAC inhibitor plus immune checkpoint inhibitor regimen and who can use a smartphone for electronic reporting.

Not a fit: Patients with serious uncontrolled comorbidities, those judged unsuitable by investigators, those who cannot use an internet-capable mobile device, or those with non‑MSS tumor types are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the project will clarify real-world safety and patient-experienced side effects to help clinicians and patients make informed treatment decisions about this combination regimen.

How similar studies have performed: Small trials such as the phase II CAPability-01 and guideline inclusion have suggested promise for similar combinations, but large prospective real-world data remain limited.
