Immunotherapy cocktail shows promise against tough rectal cancers
NCT ID NCT06884670
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether giving a mix of immunotherapy drugs (tislelizumab and IL-2) plus chemotherapy before surgery could shrink tumors more effectively in people with locally advanced rectal cancer. The trial involved 130 adults whose cancers had not spread but were hard to treat. The goal was to see if more patients could achieve a complete response, meaning no cancer remains at the time of surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tislelizumab (PD-1 inhibitor), Interleukin-2, Capecitabine, Oxaliplatin
- What this could lead to
- If successful, this combination could become a new standard neoadjuvant treatment, increasing the chance of complete tumor disappearance before surgery for rectal cancer patients.
- What could go wrong
- This is a phase 2 trial with only 130 participants, so results may not apply to all patients. The combination may cause more side effects than standard therapy, and the long-term benefits are not yet proven.

Inclusion Criteria: 1. Males and females aged between 18 and 75 years; 2. An Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1; 3. Histologically confirmed rectal adenocarcinoma; 4. Clinical stage T3-T4 or any T with node-positive (N+) disease: locally advanced; 5. Microsatellite stable (MSS) status; 6. Adequate hematological, hepatic, and renal functions. Exclusion Criteria: 1. Patients with metastatic disease (Stage IV); recurrent colorectal cancer with active bleeding, perforation, or complex conditions requiring urgent surgery; or concurrent non-colorectal cancer malignancies. 2.
