A Phase II Study of Pemetrexed Plus Gemcitabine for Metastatic/Recurrent Head and Neck Cancer (HNSCC)
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.

|Official Title:||A Phase II Study of Pemetrexed Plus Gemcitabine for Metastatic/Recurrent Head and Neck Cancer (HNSCC)|
- Overall Objective Response [ Time Frame: 2 years ] [ Designated as safety issue: No ]
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.
- Median Overall Survival [ Time Frame: 2 years ] [ Designated as safety issue: No ]To determine the median overall survival for patients with recurrent or metastatic Head and Neck Squamous Cell Carcinoma treated with pemetrexed and gemcitabine.

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.
Drug: Pemetrexed plus Gemcitabine
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. Vitamin supplementation will be as follows: Vitamin B12: 1000 µg IM injection no less than 1 week prior to the first dose of pemetrexed, and continuing approximately every 9 weeks until 3 weeks after the last dose of pemetrexed.
Folic acid: The preferred oral daily dose of folic acid is 350 to 1000 µg. Daily folate supplementation begins no less than 1 week prior to the first dose of pemetrexed and continues until 3 weeks after the last dose of pemetrexed.
For rash prophylaxis, dexamethasone (4 mg po twice per day) should be taken on the day before, the day of, and the day after each dose of pemetrexed unless clinical contraindications exist.
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.
