A Study of the Combination of Cetuximab and Methotrexate in Recurrent or Metastatic Cancer of the Head and Neck
- Conditions
- Squamous Cell Carcinoma of the Head and Neck
- Interventions
- Registration Number
- NCT02054442
- Lead Sponsor
- Radboud University Medical Center
- Brief Summary
The investigators will perform a randomized phase II study to investigate if the addition of cetuximab to MTX is beneficial for the patient. Because no data on this combination are available the investigators will start with a phase Ib study to investigate the feasibility of the schedule.
- Detailed Description
The addition of cetuximab to cisplatin and 5-FU in recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN) showed an improvement of overall survival (OS), progression free survival (PFS) and response rate (RR). However, cisplatin and 5-FU are toxic cytostatics for the vulnerable recurrent or metastatic SCCHN patient. As one of the primary goals in these patients is palliation, in some patients treatment with cisplatin, 5-FU and cetuximab is not feasible owing to a low performance score (PS of 2) or the patient refusal to receive chemotherapy, i.e. cisplatin and 5-FU, possibly influencing quality of life negatively.
Methotrexate is a cytostatic which has shown to have modest activity in recurrent or metastatic SCCHN. The RR is between 14 and 20%, the median PFS is 3 months, and there is no improvement in OS, which is only 6 months. Toxicity of MTX is very low. Patients with a PS of 2 can be treated with MTX. Patients refusing treatment with cisplatin, 5-FU and cetuximab, frequently choose MTX as palliative treatment.
No data are available on the combination of cetuximab and MTX. The investigators will perform a randomized phase II study to investigate if the addition of cetuximab to MTX is beneficial, i.e. an improvement in the PFS, for the patient. Because no data on this combination are available the investigators will start with a phase Ib study to investigate the feasibility of the schedule.

-
Time between prior treatment and inclusion in the study (> 3 months). Palliative RT in case of painful bone metastases is allowed in phase II and after 4 weeks in phase Ib
-
Ineligible (due to medical co-morbidities) or intolerant to platinum-based therapy per medical history or refusing cisplatin-based chemotherapy by the patient
-
WHO performance status 0-2.

Age >18 years
-
Adequate organ function and laboratory parameters as defined by:
- Absolute neutrophil count (ANC) ≥ 1.5 x 109 /L
- Hemoglobin (Hb) ≥ 9 g/dl 5.6 mmol/l (which may be achieved by transfusion)
- Platelets (PLT) ≥ 100 x 109/L
- AST and ALT ≤ 2.5 x ULN (upper limit of normal)

-
Recovered from all adverse events (AEs) of previous anti-cancer therapies. AEs related to prior radiotherapy are allowed.
-
Written informed consent
- Serious active infections
- Patients (M/F) with reproductive potential not implementing adequate contraceptives measures
- Prior treatment with EGFR inhibitors or MTX
- Concomitant (or within 4 weeks before randomization) administration of any other experimental drug under investigation
- Concurrent treatment with any other anti-cancer therapy.
- Central nervous system involvement
- Lung fibrosis
- Pleural effusion or ascites or other third space effusions
- History of another malignancy within 2 years prior to starting study treatment, except cured basal cell carcinoma of the skin, excised carcinoma in situ of the cervix, or other head and neck cancer.
- Pregnancy or lactation
- Any other condition that would, in the Investigator's judgment, preclude patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures, e.g. infection/inflammation, intestinal obstruction, social/psychological complications.

- Arm && Interventions
Group Intervention Description Arm A: MTX in combination with cetuximab Cetuximab The dosage of cetuximab will be i.v. 400 mg/m2 over a period of 2h for the first infusion, followed by infusions of 250 mg/m2 over 1 hour once weekly. Cetuximab will be dissolved in 500 ml NaCl 0.9%. Premedication: H1-receptor antagonist and dexamethasone. The dosage of MTX (Methotrexate) will be i.v. 40 mg/m2 once weekly, administered within 5-10 minutes. MTX will be dissolved in 50 ml NaCl 0.9%. Premedication: ondansetron 8 mg. Treatment will be continued until progressive disease, unacceptable toxicity or refusal by patient.

- Primary Outcome Measures
Name Time Method Incidence of dose limiting toxicity (DLT) During the first 4 weeks after start of the combination MTX and cetuximab In the phase Ib study: toxicity scored with CTC v 4.0\*; incidence of dose limiting toxicity (DLT) during the first 4 weeks after start of the combination
Progression free survival From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 12 months In the phase II study: progression free survival (PFS). The analysis of PFS can be performed as soon as the target event (progression or death) has been observed in 98 of the 114 subjects randomized.
- Secondary Outcome Measures
Name Time Method Overall survival (OS) Followed up to 12 months after randomization Overall survival (OS) The analysis of OS can be performed as soon as the target event has been observed in 98 of the 114 subjects randomized.
Response rate (RR) Till end of treatment The difference in RR rates between both treatment arms will be analyzed using a stratified Cochran Mantel Haenszel test at a one-sided alpha-level of 0.05. In addition to the response rates in both arms, the odds ratio will be reported together with 90% confidence intervals. The impact of various demographic and disease characteristics (e.g. HPV positivity), on RR will be investigated using an exploratory logistic regression model.
