Gopi,
Re-myelination is being looked at all over the world.
Professor Neil Scolding in the UK is looking at stems cells to re-myelinate. The last I saw he was looking at human trials in 2-3 years.

The UK MS Society is also funding a myelin repair project based in Cambridge, UK. They are looking at 5-10 years.

The Myelin Repair Foundation is focussed on Myelin repair - by the end of the decade.

Canada is also funding a myelin repair project.
Several of the drugs companies are looking at ways to promote re-myelination e.g. Acorda Therapeutics. Most are in very early stages of development.
So lots going on but difficult to say when therapies to re-myelinate will be available - perhaps within 5 years (a guess).
But the other side of the coin is to stop the de-myelination and there are obviously lots of drugs in the pipeline which seek to do this.
But it is not just re-myelination. Loss of nerve fibres e.g. axons which are covered by myelin is considered to be the cause of disability. Lots of work is on-going to look at ways to regenerate lost nerve fibes e.g. nerve growth factors.
So lots going on at halting the disease and repairing the damage. Hope this helps.
