First received: October 5, 2005
Last updated: December 14, 2007
Last verified: December 2007
The primary objective of this study is to compare the activity of raltitrexed and ZD1839 versus raltitrexed alone as second line chemotherapy in subjects with colorectal carcinoma by estimating progression free survival (PFS) in each treatment arm.

Condition Intervention Phase
Colorectal Cancer Drug: Gefitinib, raltitrexed Phase 2 Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: A Randomized, Placebo-Controlled, Double-Blind Phase 2b Study of Raltitrexed (Tomudex) and ZD1839 (Iressa) Versus Raltitrexed Alone as Second Line Chemotherapy in Subjects With Colorectal Carcinoma

  • prior chemotherapeutic regimen for metastatic or locally advanced disease with an interval of at least 4 weeks between the last administration of chemotherapy an the first administration of study treatment
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2
  • life expectancy of at least 12 weeks

Exclusion Criteria:

  • Known severe hypersensitivity to raltitrexed or any of the excipients of this product
  • known severe hypersensitivity to raltitrexed or any of the excipients of this product
  • active infection or uncontrolled diarrhoea
  • cerebral metastasis or meningeal carcinomatosis
  • any evidence of clinically active interstitial lung disease (patients with chronic stable radiographic changes who are asymptomatic need not be excluded)

  • pregnancy or breast feeding (women of child-bearing potential)
  • concomitant use of phenytoin, carbamazepine, rifampicin, barbiturates, or ST John's Wort;
  • Treatment with a non- approved or investigational drug within 30 days before Day 1 of study treatment
