简要总结
The purpose of this study is to determine if the combination of 2 chemotherapy drugs called pemetrexed and gemcitabine might be effective treatment for head and neck squamous cell cancer. The researchers want to find out what effects, good and/or bad, that this treatment has on head and neck cancer.
详细描述
Pemetrexed (500 mg/m2) and gemcitabine (1250 mg/m2) will be given together on Days 1 and 15 of a 28 day cycle in patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). Patients will not have received more than 2 prior chemotherapy regimens in the recurrent/metastatic disease setting. Vitamin B12 and folate supplementation will be administered per standard guidelines for pemetrexed chemotherapy.
The primary endpoint is the objective radiologic response rate. Radiologic imaging of evaluable disease will take place after every 2 cycles. Patients may remain on study until progression of disease or unacceptable toxicity.

入选标准
- •Patients must have microscopically confirmed epidermoid/squamous cell carcinoma (HNSCC) of the oral cavity, pharynx, larynx, paranasal sinus, or head/neck squamous cell carcinoma unknown primary.
- •Patients must have recurrent or metastatic disease which is not amenable to curative-intent therapy with surgery or radiation.
- •No more than 2 prior cytotoxic therapies in the recurrent or metastatic disease setting are permitted.
- •Patients must be at least 18 years of age.
- •Karnofsky Performance status must be ≥ 70%.
- •Disease must be measurable by RECIST criteria.
- •At least 4 weeks must have elapsed from previous radiation therapy. Patient must have recovered from the acute toxic effects of treatment prior to study enrollment.
- •Prior radiation therapy to ≤ 25% of bone marrow is allowed. Prior radiation to the whole pelvis and/or brain is not allowed.
- •Adequate organ function
- •Patients of childbearing potential must have a negative test for pregnancy at time of enrollment based on a urine or serum pregnancy test. Patients must agree to use a reliable method of birth control during and for 3 months following the last dose of study drug.
- •Patient must reside in geographic proximity to MSKCC for adequate follow-up during treatment, per investigator discretion.
- •Patients must sign an informed consent document.
排除标准
- •Previous exposure to pemetrexed (Alimta) or gemcitabine (Gemzar).
- •Pregnancy or breast-feeding.
- •Serious concomitant systemic disorders (for example, active infection) that, in the opinion of the investigator, would compromise the safety of the patient or compromise the patient's ability to complete the study.
- •History of any brain metastases.
- •Inability or unwillingness to take folic acid, vitamin B12 supplementation, or dexamethasone.
- •Patients will be excluded if they will be unable to hold use of nonsteroidal antiinflammatory agents (NSAIDS) with short elimination half lives
研究组 & 干预措施
Treatment
Patients will receive pemetrexed (500 mg/m2 IV infusion over approximately 10 minutes) followed immediately by gemcitabine (1250 mg/m2 IV infusion given over approximately 30 minutes) on day 1 and day 15 of a 28-day cycle.
干预措施: Pemetrexed plus Gemcitabine (Drug)
结局指标
主要结局
Overall Objective Response
时间窗: 2 years
To determine the objective radiologic response rate of pemetrexed and gemcitabine in patients with recurrent or metastatic Head and Neck Squamouse Cell Carcinoma. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
次要结局
- Median Overall Survival(2 years)
