More Drugs

Cladribine is a drug used to treat hairy cell leukemia. For treatment of cancer it is given by IV, but for MS, it is given orally. It is currently awaiting approval for use in MS. It is long lasting, but side effects include a reduction in white blood cells and infections like shingles. There are also some questions about cancer developing as a result of using the drug.

Fingolimod is currently in phase 3 of clinical trials and is also showing promising results. It, too, is an oral medication, but its side effects include risk of infections, heart rate and blood pressure increases, and lung and skin cancers.

Dimethyl fumarate, which I'm sure will get a sexier name at some point, has been used to treat psoriasis. It has also been used as a mold inhibitor in consumer products, though now is being banned for that use. It is showing promise as a treatment for MS because of its neuro-protective properties and its ability to inhibit pro-inflammatory cytokines (cytokines are a type of chemical messenger - reduce the inflammatory cytokines and you potentially have a treatment for MS). This drug is an oral medication currently in Phase 3 trials. Side effects included abdominal pain, flushing. and headache.

Laquinimod is currently in Phase 3 trials and has immunomodulatory effects and may offer some neuroprotection. Like the interferons, liver enzymes must be watched closely, and the drug also shows promise for treating other autoimmune diseases. And it's an oral med.

Daclizumab is a drug commonly used as an anti rejection drug for transplant patients. It increases natural killer cells and is well tolerated. There is the possible increase in infections as a side effect and it is given in injection form once a month. It is currently in Phase 3 trials.

Rituximab has been used for treatment of leukemia as an antibody against B cells. It is given by IV every six months. Side effects include viral infections and reactivation of viral infections (in particular, the JC virus which leads to PML) and cardiac arrest. Needless to say, if you take this stuff, the docs will watch you like a hawk. In Phase 2 studies, completed last year this drug has shown promise.

Alemtuzumab is another cancer therapy with a profound effect on MS. The Phase 2 trials have been completed. Side effects include low platelets and thyroid problems, so again, the docs would keep a close eye on you if you're on this drug.

There are a great many more drugs and treatments in the pipeline, but the ones I've mentioned are the ones closest to consumer use.

All of the above drugs are currently being studied and are 1-5 years away from coming on the market for treatment of relapsing remitting MS. However, these drugs have pretty serious side effects. They all show promise and studies of these drugs and the DMDs all show that earlier treatment of MS is going to lengthen the time to disability. Ideally, someone will come up with a cure. Do it now, would ya'?
