Targretin is a Rexinoid as are LGD1268, LGD1324, and other LGND and AGN second generation compounds.

ERA-327, TSE424, Droloxifene, CP-366,156, Idoxifene, Evista, Tamoxifen are SERMs

Rexinoids compete with Rexinoids

SERMs compete with SERMs

SERMs and Rexinoids don't compete, they synergize

ERA-937 competes with the SERMs above, not Targretin or othe Rexinoids

Combinations will be Rexinoids combining with SERMs, not SERMs with SERMs or Rexinoids with Rexinoids

LGND's current Phase II trial with Targretin combines a SERM (Tamoxifen) with a Rexinoid (Targretin).

Other LGND Breast Cancer trails also combine a Rexinoid (Panretin), with a SERM (Tamoxifen).

I know of no Rexinoid/Rexinoid or SERM/SERM combination trials.

You misunderstanding is at a VERY basic level.

Do you know of any SERM/SERM combos or Rexinoid/Rexinoid combos?

I believe that the only competition that Targretin has in the rexinoid treatment for breast cancer is from AGN, and they have not filed any INDs at this time.

All of the compounds in the clinic are SERMs, of which LGND has partnerships with 4 or the 5 most advanced compounds (they don't have Idoxifene, but its not clear that SBH's Idoxifene is moving forward).
