An Open-label, Randomized, Multi-Center Study to Evaluate the Efficacy and Safety of Induction Treatment With Melphalan/HDS Followed by Consolidation Treatment With Trifluridine-Tipiracil Plus Bevacizumab Versus Trifluridine-Tipiracil Plus Bevacizumab Alone in Patients With Refractory Metastatic Colorectal Cancer With Liver Dominant Disease
The goal of this clinical trial is to learn if using a liver-directed therapy with high dose chemotherapy followed by approved cancer treatment to treat patients with colorectal cancer that has spread to the liver is safe and tolerable. The clinical trial will also learn if the liver-directed therapy with high dose chemotherapy works on the disease in the liver. Investigators will compare the use of the liver-directed therapy with high dose chemotherapy followed by approved cancer treatment or approved cancer treatment alone. Participants will: * Undergo up to two liver-directed therapy with high dose chemotherapy procedures followed by approved cancer treatment or take approved cancer treatment alone * Visit clinic at least every two weeks for checkups and tests * Complete scans approximately every two months
• Histologically confirmed diagnosis of metastatic colorectal cancer and histologically or cytologically proven CRC metastases that occupy 50% or less of the liver parenchyma.
• Patient has liver-dominant metastatic disease. Liver-dominant is defined as the majority of total tumor burden is located in the liver, and the liver lesions are not resectable or treatable with ablation or are associated with extrahepatic disease that makes surgical intervention non-curative.
• Disease in the liver must be measurable (per RECIST v.1.1 guidelines) by computed tomography (CT) and/or magnetic resonance imaging (MRI).
• If there is evidence of extrahepatic metastatic disease, it is limited, and the life-threatening component of disease is in the liver. Limited extrahepatic disease is defined in this protocol as follows: up to 5 tumor lesions in the lung with longest diameter not greater than 2 cm and/or up to 5 lymph nodes that measure 2 cm or less per lesion; solitary lesions definitively treated with no sign of progression in the last 6 months.
• Scans used to determine eligibility (CT scan of the chest/abdomen/pelvis and MRI of the liver) must be performed within 28 days prior to randomization.
• Previous treatment and progressed on or following, or intolerant to, fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapy, an anti-VEGF biological therapy, and/or an anti-EGFR therapy if RAS wild-type.
• ECOG PS of 0-1 within 14 days prior to randomization.
