Assessing a Regorafenib-irinotecan Combination Versus Regorafenib Alone in Metastatic Colorectal Cancer Patients

• Status: Recruiting
• Trial end date: 2023-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Patients with metastatic colorectal cancer (mCRC) who have received all approved standard treatments (except Regorafenib and TAS 102) no longer have treatment options available while maintaining a good performance status which would allow them to receive a new treatment

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Institut du Cancer de Montpellier - Val d'Aurelle
• Treatments: Camptothecin; Irinotecan

Criteria

Inclusion Criteria:

• Signed informed consent obtained before any study specific procedures

• Male or female ≥ 18 years of age

• Histological documentation of adenocarcinoma of the colon or rectum

• Patients with metastatic colorectal cancer

• Progression during or within 3 months following the last administration of approved standard therapies, which must include a fluoropyrimidine (or raltitrexed), oxaliplatin, irinotecan, anti VEGF therapy and an anti EGFR therapy (for RAS wild-type tumors)

• ECOG performance status ≤1

• Life expectancy of at least 3 months

• Patients with A/A CCND1 genotype of rs603965 CCND1

• Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements conducted within 7 days of starting study treatment: Amylase and lipase ≤1.5 x ULN,Total bilirubin ≤ 1.5 x ULN,Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3.0 x ULN (≤ 5 x ULN for patients with liver involvement of their cancer), Alkaline phosphatase (ALP) ≤ 2.5 x ULN (≤ 5.0 x ULN for patients with liver involvement for their cancer and/or have bone metastases), Platelet count ≥ 100,000/mm3; Hemoglobin (Hb) ≥ 9 g/dL; Absolute neutrophil count (ANC) ≥ 1,500/ mm3. Transfusion to meet the inclusion criterion, Serum creatinine ≤ 1.5 x ULN

• International normalized ratio (INR) ≤ 1.5 x ULN and partialthromboplastin time (PTT) or activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN unless receiving treatment with therapeutic anticoagulation. Patients being treated with anticoagulant, e.g., heparin, will be allowed to participate provided no prior evidence of an underlying abnormality in these parameters exists. Close monitoring of at least weekly evaluations will be performed until INR and PTT are stable based on a pre-dose measurement as defined by the local standard of care

• Women of childbearing potential must have a blood or urine pregnancy test performed a maximum of 7 days before start of study treatment, and a negative result must be documented before start of study treatment

• Women of childbearing potential and men must agree to use adequate contraception before entering the study until at least 8 weeks after the last study drug administration of Regorafenib and 12 weeks after the last study drug administration of Irinotecan. The investigator or a designated associate is requested to advise the patient on how to achieve an adequate birth control. Adequate contraception is defined in the study as any medically recommended method (or combination of methods) as per standard of care.
