Methotrexate is an antimetabolite and antifolate agent with antineoplastic and immunosuppressant activities. Methotrexate binds to and inhibits the enzyme dihydrofolate reductase, resulting in inhibition of purine nucleotide and thymidylate synthesis and, subsequently, inhibition of DNA and RNA syntheses. Methotrexate also exhibits potent immunosuppressant activity although the mechanism(s) of actions is unclear.
Methotrexate is approved by the Food and Drug Administration (FDA) to be used by itself to treat the following types of gestational trophoblastic tumors, Chorioadenoma destruens, Choriocarcinoma, Hydatidiform mole. Methotrexate is also approved to be used alone or with other drugs to treat acute lymphoblastic leukemia (ALL) that has spread to the central nervous system (CNS) or to keep it from spreading there, and to treat the following, breast cancer, certain types of head and neck cancer, lung cancer, advanced non-Hodgkin lymphoma (NHL), advanced mycosis fungoides (a type of cutaneous T-cell lymphoma), osteosarcoma that has not spread to other parts of the body, following surgery to remove the primary tumor. Methotrexate is also approved to treat the following non-cancer conditions, rheumatoid arthritis, severe psoriasis.

According to new results from the WELCOME trial, exploratory data analyzing the impact of treatment with CIMZIA(®) (certolizumab pegol) - the only PEGylated anti-TNF (alpha) (Tumor Necrosis Factor alpha) - administered either every two weeks or every four weeks, showed that the majority of Crohn's disease patients in both dosing groups experienced no hospitalizations and surgical procedures during the course of the 26-week study.
New data from an open-label extension study evaluating the long-term safety and efficacy of CIMZIA® (certolizumab pegol) in moderate to severe Crohn's disease patients demonstrate that 82 percent of patients actively treated with CIMZIA - the only PEGylated anti-TNF-alpha (Tumor Necrosis Factor alpha) - remained in long-term remission without dose escalation up to 3.5 years.

Phase 3 data reported for the first time show that once every four week subcutaneous injections of SIMPONI(TM) (golimumab) resulted in significantly greater inhibition of structural damage compared with placebo plus methotrexate in patients with active rheumatoid arthritis (RA) and active psoriatic arthritis (PsA).
UCB today announced data that showed rapid and sustained improvements in ACR20, physical function, pain and fatigue of rheumatoid arthritis (RA) as early as the first week, and inhibition of progression of structural joint damage (seen at week 24) following treatment with Cimzia (certolizumab pegol), together with methotrexate (MTX), was sustained up to 100 weeks.
New long-term data from two pivotal, Phase 3 clinical trials showed that patients with active rheumatoid arthritis (RA) receiving SIMPONI(TM) (golimumab) every four weeks achieved sustained improvements in signs and symptoms and physical function response through one year. These new data were presented today at the 2009 American College of Rheumatology (ACR) Annual Scientific Meeting.
Genentech, Inc., a wholly-owned member of the Roche Group, today announced two-year results from a Phase III study, which showed that people with rheumatoid arthritis (RA) who received either a 4 mg/kg or 8 mg/kg dose of ACTEMRA® (tocilizumab), in combination with methotrexate, had no progression of joint damage, (75 and 83 percent, respectively, as assessed by radiograph) compared with people who received methotrexate alone (66 percent).
Genentech, Inc. a wholly-owned member of the Roche Group, and Biogen Idec announced today that the companies received a Complete Response from the U.S. Food and Drug Administration (FDA) for a supplemental Biologics License Application (sBLA) for Rituxan (rituximab) plus methotrexate (MTX) in patients with moderately-to-severely active rheumatoid arthritis (RA) who no longer respond to treatment with a disease modifying antirheumatic drug (DMARD), including MTX.
Using medication that reduces or blocks the actions of folic acid during the first trimester of pregnancy (weeks 1-12), increases the risk that the growing baby will develop abnormalities.
