ClinConnect Summary
The NIPIRESCUE clinical trial is studying the effectiveness of two medications, nivolumab and ipilimumab, for patients with advanced colorectal cancer that has not responded to previous treatments. This trial specifically targets those with a certain type of cancer called MSI/dMMR, which means the cancer cells have specific genetic features. To qualify for this study, patients must be at least 18 years old, have confirmed metastatic colorectal cancer that cannot be completely removed by surgery, and have experienced disease progression after receiving anti-PD1 monotherapy along with other standard treatments.
Participants in this study can expect to receive the combination of nivolumab and ipilimumab, which are both types of immunotherapy designed to help the immune system fight cancer. Throughout the trial, patients will undergo regular check-ups and imaging tests to monitor their condition. It’s important for potential participants to know that they will need to provide fresh tumor samples and meet specific health criteria before joining. This research aims to find better treatment options for patients whose cancer has not improved with existing therapies.

- • 3. Eastern Cooperative Oncology Group performance status (ECOG PS) of 0, 1, and 2,
- • 4. Histologically confirmed colorectal adenocarcinoma,
- • 5. Documented metastatic disease not suitable for complete surgical resection,
- • 6. Disease progression per iRECIST criteria (i.e., iCPD: immune confirmed PD) during monotherapy with anti-PD1 monoclonal antibody or less than 6 months after the discontinuation of anti-PD1 monoclonal antibody
- • 7. Disease progression during, after, or patients who are intolerant or have contraindications to approved standard therapies for the metastatic disease, which must include at least: • Fluoropyrimidine, oxaliplatin, and irinotecan, • Anti-EGFR therapy if wild-type RAS, • Anti-VEGF therapy,
- • 8. At least one measurable lesion as assessed by CT-scan or magnetic resonance imaging (MRI) according to RECIST 1.1 and feasibility of repeated radiological assessments,
- • 9. dMMR and/or MSI tumor status defined by: - Loss of MMR protein expression using immunohistochemistry with four (anti-MLH1, anti-MSH2, anti-MSH6, and anti-PMS2) antibodies, - and/or ≥ two unstable markers by pentaplex polymerase chain reaction (BAT-25, BAT-26, NR-21, NR-24, and NR-27), NB: In case of loss of expression of only one MMR protein immunohistochemistry, it is necessary to confirm the tumor is MSI using pentaplex PCR.
- • NB: In cases with two unstable markers, comparison with matching normal tissue is required.
- • NB: Agreement of the Sponsor (GERCOR) is mandatory to include the patient (the patient's file will be verified to confirm MSI/dMMR status before inclusion \[an anonymized fax\] and confirmation of a patient's allocation will be sent by mail to the Investigator within 24h).
- • 10. For all patients, a new biopsy must be performed to obtain fresh anti-PD1 resistant tumor tissue prior to study treatment initiation,
- • 11. For all patients, archival formalin-fixed paraffin-embedded tissue (FFPE) blocks and/or FFPE unstained slides (minimum of 30 positively charged slides representative of tumor tissue and non-tumor adjacent prior to anti-PD1 therapy (i.e., primary or metastatic site naïve of immunotherapy) must be submitted to the central laboratory,
- • 12. Adequate hematologic and end-organ function, defined by the following laboratory test results, obtained within 7 days prior inclusion: - Adequate hematological status (White blood cell \> 2000/μL; o Neutrophils \> 1500/μL; Platelets \> 100.000/μL; Hemoglobin \> 10.0 g/dL; - Adequate renal function: Serum creatinine level \< 120 μM; Clearance \> 50 ml/min (Modification of the Diet in Renal Disease \[MDRD\] or Cockcroft and Gault, - Adequate liver function: Serum bilirubin ≤ 1.5 x upper normal limit (ULN); Alkaline phosphatase (ALP) ≤ 3.0 x ULN; Alanine aminotransferase (ALT) ≤ 3.0 x ULN; Aspartate aminotransferase (AST) ≤ 3.0 x ULN; Hemostasis: Prothrombin time (PT)/International normalized ratio (INR) and activated partial PT (aPTT) ≤ 1.5 x ULN unless participants are receiving anticoagulant therapy and their INR is stable and within the recommended range for the desired level of anticoagulation,
- • 13. Females of childbearing potential must have negative serum pregnancy test within 7 days before starting study treatment,
- • 14. Women of childbearing potential should use effective contraception during treatment and at least 5 months thereafter.
- • 15. Registration in a national health care system (Protection Universelle Maladie \[PUMa\] included)
- Exclusion Criteria:
- • 1. Known brain metastases or leptomeningeal metastases,
- • 2. Persistence of toxicities related to prior treatments (chemotherapies or anti-P1 therapies) grade \> 1 (NCI CTCAE v 5.0; except dysthyroidism, adrenal gland deficiency, alopecia, fatigue or oxaliplatin-induced peripheral sensory neuropathy which can be ≥ grade 2),
- • 3. Discontinuation of anti-PD1 treatment due to treatment-related adverse event (AE) grade \> 2 (NCI CTCAE v 5.0),
- • 4. Prior treatment with an anti-LAG-3, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways, including prior therapy with anti-tumor vaccines or other immuno-stimulatory antitumor agents, except anti-PD1 antibodies,
- • 5. Concomitant unplanned antitumor therapy (e.g. chemotherapy, molecular targeted therapy, radiotherapy, immunotherapy),
- • 6. Major surgical procedure within 4 weeks prior to initiation of study treatment,
- • 7. Patients receiving any investigational drug, biological, immunological therapy within the previous 21 days before study treatment,
- • 8. Patients with an active, known, or suspected autoimmune disease. Patients with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to be enrolled,
- • 9. History of interstitial lung disease or pneumonitis,
