Brief Summary:
This study is single center single arm prospective phase II study. In this study, efficacy and side effects of pemetrexed as salvage regimen on patients who failed all standard chemotherapy and total of 29 patients will be enrolled. Pemetrexed will be continued until disease progression is happened.

Condition or disease Intervention/treatment Phase
Colo-rectal Cancer Drug: Pemetrexed Drug: Tarceva 100Mg Tablet Phase 2

Detailed Description:

Antitumor effect of pemetrexed is already proven lung cancer, pleural mesothelioma, peritoneal mesothelioma and has been used as a standard therapeutic agent. In addition, this drug does not have severe side effects, pemetrexed is thought to be an important option for patients with poor performance status or elderly patients. Pemetrexed has been studied in colorectal cancer, Zhang et al have demonstrated that pemetrexed combined with gefitinib has a significantly synergistic effect on colorectal cancer cells (17). In two phase II studies in which patients received pemetrexed as first-line treatment for metastatic disease, objective response rates were 15 - 17 %. These trials were conducted prior to supplementation with folic acid and vitamin B12, which markedly decreased the frequency of hematologic toxicities of pemetrexed; routine supplementation is now included in all clinical trials of the agent (18).

Erlotinib (tarceva) is oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI). Erlotinib showed the effect in the maintanence therapy (combined with bevacizumab) in colorector cancer. Also, erolitinib had the effect in biliary tract cancer and pancreatic cancer. Our previous phase III trial for tarceva puls GEMOX (gemcitabine plus oxaliplatin) reported that adding to tarceva to GEMOX had more useful in the specific subgroup with EFGR overexpressed patients.

The aim of present study is to assess treatment efficacy and side effects of pemetrexed plus tarceva on EGFR overexpressed patients with refractory colorectal cancer and no treatment option whose performance status is relatively preserved.

Arm Intervention/treatment
Experimental: Pemetrexed+Tarceva
Pemetrexed 500 mg/m2 IV Q 3 weeks Tarceva 100mg once daily, continous
Drug: Pemetrexed
Pemetrexed is a multitarget antifolate (MTA) whose mechanism of action relies mainly on the inhibition of TS, with weaker secondary effects on glycinamide ribonucleotide formyltransferase (GARFT) and dihydrofolate reductase (DHFR), leading to impairment of DNA synthesis and repair.

Drug: Tarceva 100Mg Tablet
Erlotinib (tarceva) is oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI).

Primary Outcome Measures :
  1. Overall Response Rate [ Time Frame: 6 months ]
