… but at present, methotrexate is generally reserved for treatment of active or relapsing Crohn's disease in those refractory to or intolerant of thiopurines or anti-TNF agents. (2 nd European CD guideline) Dignass et al. 2010; Chande et al Use of Methotrexate in IBD Recommendations … at present there is no evidence supporting the use of methotrexate for induction or maintenance of remission in active ulcerative colitis. Cochrane review Methotrexate Ulcerative Colitis

What are the reasons? Efficacy Toxicity Patient preference Missing Data Therapeutic Use for Methotrexate Compared to Azathioprine/ 6-MP in USA “Nonexistent”
Data for Use of Methotrexate in Crohn’s Disease Sneak Preview: Data for Use of Methotrexate in Ulcerative Colitis Safety and Toxicity of Methotrexate Practical Approach Outline
Cochrane-Analyses of Therapeutic Efficacy of Methotrexate or Azathioprine In Crohn’s Disease Number of trials Patients (drug or placebo) NNT AZA / 6-MP Induction No difference to placebo, but significant steroid sparing MTX Induction 1 (6 low quality or very small) 1415 AZA / 6-MP Maintenance 7/ / 4 MTX Maintenance 1 (4 low quality) 764 McDonald et al. 2014, Patel et al. 2014, Chande et al. 2013, Prefontaine et al. 2010

Immunosuppression SONIC no previous immunosuppression vs COMMIT 25% previous exposure and failure of azathioprine Inclusion criterion SONIC: CDAI > 220 and need for steroids, COMMIT patient in need for steroids (15-40mg) in the previous 4 weeks SONIC >70% prednisone naive at inclusion vs. COMMIT mean dose of prednisone 22 mg Trial Design SONIC: Dual therapy (IFX + AZA) vs COMMIT initial Steroid taper which might have masked the effects of MTX Differences SONIC and COMMIT
Methotrexate in Ulcerative Colitis … at present there is no evidence supporting the use of methotrexate for induction and maintenance of remission in active ulcerative colitis. Cochrane review 2014 Methotrexate Ulcerative Colitis
Clinical Studies MTX in UC Randomized, double blind, prospective trial investigating the efficacy of Methotrexate in induction and maintenance of steroid free remission in ulcerative colitis (MEthotrexate Response In Treatment of UC - MERIT-UC) Comparison of Methotrexate vs Placebo in Steroid- Refractory Ulcerative Colitis (METEOR)
MTX 25 mg sq /weekly* + folic acid+ steroid taper Randomization if clinical response or remission and off steroids week 16 Randomization if clinical response or remission and off steroids week 16 MTX 25 mg/weekly*+ folic acid+ 5-ASA** Placebo /weekly +folic acid+ 5- ASA** Primary Endpoint Remission (relapse free survival) and off steroids week 48 Primary Endpoint Remission (relapse free survival) and off steroids week 48 Induction Period Week 1-16 Maintenance Period Week Dosis reduction to 15 mg sq/weekly in case of MTX side effects ** no 5-ASA in case of intolerance Methotrexate Response in Treatment of Ulcerative Colitis – MERIT-UC
MERIT-UC Trial – Response and Remission after Open Label MTX Induction Therapy for 16 Weeks Remission: Steroid-free for 4 weeks + Clinical Mayo ≤ 2 Response: Steroid-free for 4 weeks + decrease in the Clinical Mayo score of ≥ 2 points and at least a 25% decrease from baseline Mayo score > 50% previous failure of anti-TNF + azathioprine

Kremer et al No cases of Liver cirrhosis
113 low dose MTX exposed men/pregnancies vs 412 non-MTX exposed men/pregnancies. No differences in major birth defects, spontaneous abortion, gestational age at delivery or birth weight. Methotrexate and Planned Pregnancy Weber-Schoendorfer et al Stop methotrexate at least 3 months before planned pregnancy: High risk for Birth defects, not advised during lactation. FDA category x. Stop methotrexate at least 3 months before planned pregnancy. “Expert opinion” in 2008.
How to start therapy with Methotrexate Approach
Assess for clinical risk factors Laboratory work up Radiology Consideration of following tests: Obesity Diabetes mellitus Alcohol intake AST, ALT Albumin CBC Creatinine Chest X-ray to rule out interstitial lung disease Serology testing for: Hepatitis B, C HIV Pregnancy Test Lipid profile Blood fasting glucose Recommended Tests Before Start of Methotrexate Visser et al. 2009
25 mg MTX sc + 1mg folic acid Steroid Taper (8 weeks) + 1mg folic acid daily Induction 25 mg MTX sc + 1 mg folic acid + 1 mg folic acid daily Maintenance Once Weekly Subcutaneous Methotrexate Mono Therapy In case of nausea: Ondansentron 4-8 mg before and on day after injection.
CBC, LFTs, creatinine, albumin Induction week 2, 4, 8 CBC, LFTs, creatinine, albumin Maintenance q 8-12 weeks Monitoring Methotrexate Therapy In case of normal LFTs and no risk factors for cirrhosis (NASH, alcohol) long term no need for liver biopsy.
Conclusion Methotrexate is underused (“ignored”), but is a viable therapeutic alternative in Crohn’s disease with similar efficacy as azathioprine/6-MP. METEOR and MERIT-UC will clarify if MTX is effective in ulcerative colitis. Methotrexate seems to be not “unsafer” compared to azathioprine or anti-TNF agents.
New: MTX in UC (?) The other bunch Methotrexate in 2015/2016
