A Phase II, Single-Center, Open-Label Study Of Oral Panobinostat (LBH589) When Administered In Combination With Lenalidomide And Weekly Dexamethasone In Patients With Multiple Myeloma

The study drug, panobinostat, is made by Novartis Pharmaceuticals Corporation. Panobinostat
has not yet been approved by the Food and Drug Administration (FDA) and thus is considered
an experimental drug in this research study. Panobinostat is not available to you "on the
market" (available for you to buy). It is only available in clinical trials for patients
like you with your medical condition. Panobinostat is a drug that may slow down the growth
of multiple myeloma or kill multiple myeloma cells by blocking certain enzymes (proteins
produced by cells). Panobinostat has shown effects against cancers such as multiple myeloma
in laboratory studies and in studies using animals; however, it is not known if this
medicine will show the same activity in humans. As of 31st December 2009, a total of 1116
patients have already received treatment with panobinostat.

Unlike panobinostat, lenalidomide (Revlimid©) and dexamethasone are approved by the FDA and
are already available for purchase on the US market. Clinical trials have shown that
lenalidomide, especially taken with dexamethasone, produces positive clinical responses with
manageable side effects when given to subjects with multiple myeloma.

In this study, subjects will take panobinostat capsules, lenalidomide, and dexamethasone all
orally. The purpose of this combination is to interfere with the cancerous cells in multiple
and different ways as each of these drugs acts differently on cancer cells. By combining the
drugs and giving them at the same time, it might be possible to slow the progression of your
disease, rather than if study drugs were given separately. Researchers have combined
laboratory studies on animals with this drug combination and the combined effect has been
shown to be worthwhile to justify clinical trials in humans.
