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.
Abbott has announced that it has received approval from the European Commission to market Humira (adalimumab) as a treatment for psoriatic arthritis and early rheumatoid arthritis (RA) in Europe.
University of Michigan scientists have created the nanotechnology equivalent of a Trojan horse to smuggle a powerful chemotherapeutic drug inside tumor cells - increasing the drug's cancer-killing activity and reducing its toxic side effects.
Results from the DANCER study presented today revealed that MabThera significantly improves symptoms in heavily treated patients who are affected by moderate-to-severe rheumatoid arthritis (RA), a painful and debilitating disease of the joints.
An international team of researchers, led by Dr. Earl Silverman of The Hospital for Sick Children (Sick Kids), has found that two arthritis medications (methotrexate and leflunomide) commonly used in adults are safe and effective in children. This research is reported in the April 21, 2005 issue of The New England Journal of Medicine.
MPs gathered at the House of Commons on Tuesday (April 5th) as experts and patient groups urged members of parliament to lobby for improved access to treatment for patients with psoriatic arthritis, a little known and poorly understood condition in which patients experience symptoms of both psoriasis and arthritis.
Drinking green tea has a protective effect against some forms of cancer but drinking large amounts can increase the risk of birth defects such as spina bifida – according to previous epidemiological studies.
A Johns Hopkins-led study designed to evaluate the ability of etanercept to maintain disease remissions in a serious autoimmune disorder has failed to show any benefit. Etanercept, also called Enbrel, is a common treatment for rheumatoid arthritis and other types of joint inflammation.
The most common medical approach to terminating early pregnancy — the drug RU-486 plus prostaglandins — remains the most effective nonsurgical abortion method, according to a new research review.
A major cause of pain and disability, rheumatoid arthritis (RA) is also potentially the most treatable form of chronic arthritis. Researchers, doctors, and patients agree that a group of drugs called disease-modifying antirheumatic drugs (DMARDs) can effectively reduce joint pain and stiffness.
Genmab announced today the US Food and Drug Administration (FDA) accepted its Investigational New Drug Application (IND) to start a Phase I/II dose escalation trial for HuMax-CD20 to treat patients with active rheumatoid arthritis (RA) who have failed one treatment with one or more disease modifying anti-rheumatic drugs (DMARDs).
Acute lymphoblastic leukemia (ALL) is a malignant disease caused by the abnormal growth and development of white blood cells (WBC) in the bone marrow and blood. ALL is the most common cancer occurring in children with an annual rate of approximately 30 to 40 new cases per million.
A new study published today in Arthritis & Rheumatism demonstrates that Remicade (infliximab) is able to reverse the symptoms of the debilitating disease rheumatoid arthritis (RA) in patients who are newly diagnosed.
Rheumatoid arthritis patients receiving the recommended starting dose (3mg/kg) of infliximab (REMICADE®) have no more serious rate of infections than do patients taking methotrexate alone
Rheumatoid arthritis patients have an approximately two-fold increased morbidity and mortality in infections compared to a population without the disease.
The study will examine how much of an improvement in pain, stiffness, function and other symptoms is needed before patients consider the change important.
A new clinical study to determine how people with rheumatoid arthritis (RA) evaluate improvements in disease symptoms will be carried out by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the Department of Health and Human Services' National Institutes of Health.
Committee for Medicinal Products for Human Use of the European Agency for the Evaluation of Medicinal Products has issued a positive opinion recommending approval of expanded labeling for REMICADE(R) (infliximab), in combination with methotrexate, for treatment of active and progressive psoriatic arthritis (PsA) in patients who have responded inadequately to disease modifying anti- rheumatic drugs (DMARDs).
The difference in cost associated with using two common treatments for psoriasis over the course of one year with treatment lasting 16 weeks are small.
Genentech, Inc., Biogen Idec and Roche have announced that the New England Journal of Medicine published the results of a Phase IIa study showing that two doses of Rituxan® (Rituximab), administered two weeks apart, improved symptoms in patients with moderate-to-severe rheumatoid arthritis (RA) for up to 48 weeks when combined with methotrexate (MTX), compared to MTX alone.
New results from TEMPO (Trial of Etanercept and Methotrexate with Radiographic Patient Outcomes) demonstrated that Enbrel® (etanercept) therapy allowed significantly more rheumatoid arthritis (RA) patients to achieve clinical remission at two years compared to patients treated with methotrexate alone.
