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.

Rheumatoid arthritis patients treated with biologic response modifiers for at least 6 months do not have a greater risk for malignancy than those given other disease-modifying drugs or placebo, conclude US and Spanish researchers.
Zalicus Inc., a biopharmaceutical company that discovers and develops novel treatments for patients suffering from pain and immuno-inflammatory diseases, today announced top line results from its randomized, double-blind, placebo-controlled, Phase 2b clinical trial of Synavive in rheumatoid arthritis.

Protalex, Inc., a clinical stage biopharmaceutical company focused on the development of a class of drugs designed to treat autoimmune and inflammatory diseases including rheumatoid arthritis (RA), today announced results from its recently completed Phase 1b randomized, multiple-dose, dose-escalation study.
The incidence is about 1-3% of all breast cancers. The incidence seems to be increasing due to women delaying their childbearing to when they are in their thirties.
Pfizer Inc. announced today that the U.S. Food and Drug Administration (FDA) has extended the action date by three months for the New Drug Application (NDA) for tofacitinib, an investigational oral treatment for adults with moderately to severely active rheumatoid arthritis (RA).
An international multi-site trial has launched to determine whether a common anti-inflammatory drug can reduce heart attacks, strokes, and deaths due to cardiovascular disease in people at high risk for them. This study is being supported by the National Heart, Lung, and Blood Institute (NHLBI), a part of the National Institutes of Health.
The novel oral Janus kinase inhibitor tofacitinib significantly reduces signs and symptoms of rheumatoid arthritis, report two phase III trials published in TheNew England Journal of Medicine.
Pfizer Inc. announced today top-line results from ORAL Start (A3921069), a Phase 3 study of the investigational agent tofacitinib, a novel, oral Janus kinase (JAK) inhibitor for the treatment of adults with moderate-to-severe active rheumatoid arthritis (RA).
Protalex, Inc., a clinical stage biopharmaceutical company that is developing a class of drugs designed to treat a wide array of autoimmune and inflammatory diseases today announced preliminary findings from its recently completed Phase 1b randomized, multiple-dose, dose-escalation study.
Researchers from Austria have determined that patients with rheumatoid arthritis (RA) and their doctors differ on perception of RA disease activity.
Researchers from Austria have determined that patients with rheumatoid arthritis (RA) and their doctors differ on perception of RA disease activity. The study now available in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR) and published by Wiley, reports that RA patients cite joint pain as the reason for their perception of a change in their disease activity. Rheumatologists, however, stressed joint swelling as the major determinant for their perception of change in RA disease activity.
An HIV drug that redirects immune cell traffic significantly reduces the incidence of a dangerous complication that often follows bone marrow transplants for blood cancer patients, according to research from the Perelman School of Medicine at the University of Pennsylvania that will be published today in the New England Journal of Medicine.
Children with low-risk Hodgkin lymphoma who respond well to chemotherapy may not require additional radiotherapy, suggest study results.
Cigarette smoke reduces the production of a Fallopian tube gene known as "BAD", which helps explain the link between smoking and ectopic pregnancy. The finding, from scientists led by Drs Andrew Horne and Colin Duncan at the Medical Research Council (MRC) Centre for Reproductive Health in Edinburgh, UK, was described today at the annual meting of ESHRE (European Society of Human Reproduction and Embryology) in Istanbul.
A multicenter trial showed that nearly half of young patients with early-stage Hodgkin lymphoma can be cured without undergoing either irradiation or intensive chemotherapy that would leave them at risk for second cancers, infertility, heart and other problems later.
Researchers at Moffitt Cancer Center have conducted a clinical trial aimed at preventing graft vs. host disease (GVHD) in patients who have received hematopoietic (blood) cell transplants (HCT). The study, comparing the drug tacrolimus (TAC) in combination with either methotrexate (MTX ) or sirolimus (SIR), found that the sirolimus/tacrolimus (SIR/TAC) combination was more effective in preventing grades II-IV acute GVHD and moderate-severe chronic GVHD after allogeneic blood cell transplantation.
