D,L-MEthadone and mFOLFOX6 in Treatment of Advanced Colorectal Cancer (MEFOX)
A Phase I/II Trial of D,L-MEthadone and mFOLFOX6 in Treatment of Advanced Colorectal Cancer - The AIO-MEFOX Trial (AIO-KRK-0119)
This is a phase I/II-trial with D,L-methadone and mFOLFOX6 in the treatment of patients with histologically confirmed chemo-refractory colorectal carcinoma.
The aim of the phase-I trial is to evaluate the toxicity-profile and the dose-limiting toxicity of D,L-methadone combined with mFOLFOX6. Furthermore, to estimate the maximum tolerated dose and the recommended dose for phase-II-trial in the treatment of patients with histologically confirmed colorectal carcinoma not amenable to or progressing while having received all standard therapies.
The primary endpoint of the randomized phase-II study is to determine the disease control rate 12 weeks after randomization of patients with histologically confirmed advanced colorectal carcinoma upon treatment with D,L methadone plus mFOLFOX6 versus mFOLFOX6 alone. Overall response rate according to RECIST1.1, progression free survival (PFS), overall survival (OS), quality of life (QoL) according to the EORTC QLQc30 questionnaire, patient-reported outcomes and safety will be evaluated as secondary objectives.

- Severe non-healing wounds, ulcers or bone fractions
- Evidence of bleeding diathesis or coagulopathy
- Patients not receiving therapeutic anticoagulation must have an INR ≤ 1.4 or PTT ≤ 40 sec within 28 days prior to randomization. The use of full dose anticoagulants is allowed as long as the INR or PTT is within therapeutic limits (according to the medical standard in the institution)
- Major surgical procedures or significant traumatic injury within 28 days prior to randomization, or anticipation of the need for major surgical procedure during the course of the study.
- Pregnancy or breastfeeding women.
- Use of cannabinoids because of overlapping and /or potentiating of potential side effects
- Concomitant daily use of opioids in the last 3 months including methadone prior start of study medication
- Subjects with known allergies to the study drugs or to any of its excipients.
- Treatment with another investigational drug or participation in another interventional trial (within the 14 days prior randomization or 5 plasma half-lifes of the used investigational drug, whatever is longer)
- Congenital QT-syndrome.
- Alcohol abuse.
- Bronchial asthma.
- Liver cirrhosis > Child-Pugh classification A.
- Any psychological, familial, sociological or geographical condition potentially compromising compliance with the study protocol and the follow-up schedule; those conditions should be discussed with the patient prior to registration in the trial

The EORTC QLQ-C30 is composed of a global health status/QoL-score, five function scales, three symptom scales and five single items (dyspnea, insomnia, appetite loss, constipation, diarrhea). Each item has four response alternatives: (1) "not at all", (2) "a little", (3) "quite a bit", and (4) "very much" - except the two items of the global health-status/quality of life scale which have response options ranging from (1) "very poor" to (7) "excellent". |
