Ruzlin is a TZD that activates a receptor, PPARgamma, that turns on genes which
overcome insulin resistance. The activated receptor partners with another hormone
receptor, RXRalpha. LGND's and AGN's rexinoids activate RXRalpha. Thus in animal
models of type II diabetes, they have been shown to synergize with TZDs like WLA's
Rezulin and SBH's Avandia (and TZDs are effective at lower concentrations which may
avoid the liver problems).
Some details at home.att.net

LLY is supposed to begin Phase II clinical trials in the US soon using Targretin as
monotherapy (and possibly combination therapy with Rezulin and other approved
treatments for diabetes). LLY is also supposed to file INDs for one of LGND's second
generation rexinoids (LGD1268 or LGD1324). A few days ago, AGN announced a deal
with WLA to develop AGN's rexinoids (LGND gets royalties). The Rezulin problems
may
have helped seal the AGN/WLA deal.

LGND had talked extensively with WLA last summer, but WLA did not want to give
LGND up front funds. Consequently, LGND signed a $200 million deal with LLY,
including $50 million up front and $75 million tied to early milestones such as starting US
trials with Targretin or filing INDs for LGD1268 or LGD1324.
