Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The primary objective is to determine safety, feasibility and the recommended phase II dose (RP2D) of a combination treatment consisting of TAS-102 and Regorafenib in subjects with mCRC who have progressed after standard therapy.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NON_RANDOMIZED

Intervention Model

SEQUENTIAL

According to the standard 3+3 dose finding strategy, a safety assessment will be performed after the test of each dose level (patient cohorts of n=3) and the frequency of DLTs determined. Based on the results the dose for the consecutive patient cohort will either be escalated (0/3 DLTs), repeated (1/3 DLTs) or deescalated (\>1/3 DLTs).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Written informed consent and any locally-required authorization (EU Data Privacy Directive in the EU) obtained from the subject prior to performing any protocol-related procedures, including screening evaluations
2. Age ≥ 18 years at time of study entry
3. Histological or cytological documentation of adenocarcinoma of the colorectal region (CRC)
4. Metastatic disease not amenable to surgical resection with curative intent
5. Study treatment must constitute 3rd-line treatment for metastatic disease. Prior treatment lines must encompass at least one fluoropyrimidine-based chemotherapy, an anti-VEGF and, in case of RAS wildtype tumors, an anti-EGFR treatment.
6. Patients treated with oxaliplatin in an adjuvant setting need to have progressed during or within 6 months of completion of adjuvant therapy to be counted as prior treatment line. Note: Neoadjuvant, perioperative or adjuvant regimens with progression more than 6 months after completion are not considered as prior treatment line for metastatic disease.
7. Measurable disease, defined as at least one unidimensional measurable lesion on a CT scan as defined by RECIST 1.1
8. Eastern Cooperative Oncology Group (ECOG) performance status \<2 and life expectancy of at least 3 months
9. Adequate bone marrow, renal, and hepatic function, as evidenced by the following within 7 days prior to study treatment initiation:

* Absolute neutrophil count (ANC) ≥1,500/mm3
* Platelets ≥100,000/mm3
* Hemoglobin ≥9.0 g/dL
* Serum creatinine ≤1.5 x upper limit of normal (ULN)
* Glomerular filtration rate (GFR) ≥30 mL/min/1.73m2
* AST and ALT ≤2.5 x ULN (≤5.0 × ULN for patients with liver involvement of their cancer)
* Bilirubin ≤1.5 X ULN
* Alkaline phosphatase ≤2.5 x ULN (≤5 x ULN with liver involvement of their cancer)
* Amylase and lipase ≤1.5 x ULN
* Spot urine must not show 1+ or more protein in urine or the patient will require a repeat urine analysis. If repeated urinalysis shows 1+ protein or more, a 24-hour urine collection will be required and must show total protein excretion \<1000 mg/24 hours
* INR/PTT ≤1.5 x ULN (Patients who are therapeutically treated with an agent such as warfarin or heparin will be allowed to participate provided that no prior evidence of underlying abnormality in coagulation parameters exists. Close monitoring of at least weekly evaluations will be performed until INR/PTT is stable based on a measurement that is pre-dose as defined by the local standard of care.)
10. Women of childbearing potential and male subjects must agree to use adequate contraception for the duration of study participation and up to 6 months following completion of therapy. Females of childbearing potential who are sexually active with a non-sterilized male partner must use 2 methods of effective contraception from screening, and must agree to continue using such precautions for 6 months after the final dose of investigational product.
11. Female subjects must either be of non-reproductive potential (ie, post-menopausal by history: ≥60 years old and no menses for ≥1 year without an alternative medical cause; OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of bilateral oophorectomy) or must have a pregnancy test performed at a maximum of 7 days before start of treatment, and a negative result must be documented before start of treatment.
12. In the assessment of the investigator, patient is able to comply with study requirements.
13. Subject is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.
