Information provided by (Responsible Party):
Royal Marsden NHS Foundation Trust
To assess the efficacy of methotrexate in a genetically selected population of patients with advanced colorectal cancer, who have loss of a particular gene, MSH2. The efficacy of methotrexate will be evaluated by the proportion of cases that have a significant response to treatment (objective response rate).

Condition Intervention Phase
Advanced Colorectal Cancer Drug: Methotrexate Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Primary Outcome Measures:
  • Objective response rate, to include complete response and partial response, as defined radiologically using RECIST (Response, Evaluation Criteria in Solid Tumours) on imaging CT scans performed during treatment.

Secondary Outcome Measures:
  • Disease stabilisation rate; progression free survival; 1 year survival and median overall survival; Quality of Life assessment; toxicity assessment.

Enrollment: 2
Study Start Date: February 2009
Study Completion Date: September 2014
Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Methotrexate
    study subjects will receive methotrexate intravenously on day 1 and day 8 of a 3 weekly cycle.
Detailed Description:
The study will involve treating 29 subjects with methotrexate given intravenously. All subjects will receive treatment; there is no control arm or randomisation. The subjects will be known to have deficiency of MSH2, or a mutation (genetic change) in MSH2 that stops it functioning normally. This can either be demonstrated by testing for loss of MSH2 protein in the tumour itself, or by the demonstration of a mutation in the MSH2 gene in the subject's blood.
