10-Edam (10-ethyl-10-deaza-aminopterin), an antifolate derivative, was administered to 14 chemotherapy-naive patients with advanced colorectal carcinoma. The drug was given weekly by intravenous route at an initial dose of 80 mg/m2, with escalation or attenuation according to tolerance. Mucositis was dose limiting and occurred in 11 of 14 patients (78.6%). Removal from the study was required in one patient due to progressive pulmonary fibrosis that was histologically identical to methotrexate-induced lung damage. Toxicity was otherwise mild to moderate and included diarrhea, constipation, abdominal discomfort, anorexia, nausea/vomiting, rash, and fatigue. There were no responses to 10-Edam in this study, 95% confidence interval (0-0.23). Stable disease was achieved in four patients; the remaining 10 patients demonstrated progression within 9 weeks of initiating systemic therapy. 10-Edam employed at this dosage and schedule was not effective as a treatment against advanced colorectal carcinoma.

On September 27, 2006, the U.S. Food and Drug Administration granted approval to panitumumab (Vectibix, Amgen, Inc., Thousand Oaks, CA) for the treatment of patients with epidermal growth factor receptor (EGFR)-expressing, metastatic colorectal carcinoma with disease progression on or following fluoropyrimidine-, oxaliplatin-, and irinotecan-containing chemotherapy regimens. Panitumumab approval is based on the results of a single, open-label, randomized, multinational study that enrolled 463 patients with EGFR-expressing (at least 1+ membrane staining in > or =1% of tumor cells) metastatic colorectal cancer. Patients were randomized to either best supportive care (BSC) alone or BSC plus panitumumab, 6 mg/kg i.v., every other week. The primary study endpoint was progression-free survival (PFS), determined by an independent review committee that was blinded as to treatment assignment. BSC patients who progressed were eligible to receive panitumumab. The study patients' median age was 62 years, with 40% aged > or =65; 63% were male, 99% were white, 86% had a baseline Eastern Cooperative Oncology Group performance status score of 0 or 1, and 67% had colon cancer. The median time from diagnosis of metastases was approximately 19 months and the median number of prior therapies was 2.4. The PFS duration was significantly longer among patients randomized to receive panitumumab in addition to BSC (n = 231) compared with BSC alone (n = 232). The median and mean PFS times were 56 and 96.4 days, respectively, for patients receiving panitumumab and 51 and 59.7 days, respectively, for patients receiving BSC alone. Nineteen partial responses (8%, 95% confidence interval [CI], 5.3%-12.5%) were observed in panitumumab treated patients. The median duration of response was 17 weeks (95% CI, 16-25 weeks). Approximately 75% of patients in the BSC alone arm crossed over to receive panitumumab after disease progression. There was no difference in overall survival between the two study arms. The most common adverse events were skin rash, hypomagnesemia, paronychia, fatigue, abdominal pain, nausea, and diarrhea. The most serious adverse events were pulmonary fibrosis, severe dermatologic toxicity complicated by infectious sequelae and septic death, infusion reactions, abdominal pain, hypomagnesemia, nausea, vomiting, diarrhea, and constipation.
