Santen and TRACON Discontinue Development of DE-122 for Wet Age-Related Macular Degeneration

OSAKA, Japan and SAN DIEGO, March 09, 2020 (GLOBE NEWSWIRE) -- Santen Pharmaceutical Co., Ltd. Co., Ltd. (Head Office: Osaka; hereinafter, “Santen”) and TRACON Pharmaceuticals, Inc. (Head Office: San Diego, CA; hereinafter, “TRACON”) today announced the discontinuation of the development of DE-122 for the treatment of wet age-related macular degeneration (wAMD) following the review of recently obtained top-line data from the Phase 2a AVANTE clinical study.

The Phase 2a AVANTE clinical study is a randomized controlled trial that assessed visual acuity in wAMD patients following six monthly treatments with a combination of DE-122 and Lucentis or single agent Lucentis. Topline data indicated that DE-122 did not improve visual acuity when combined with Lucentis as compared to single agent Lucentis treatment, the primary endpoint of the trial.  Following review of the data, the two companies have decided to discontinue the development of DE-122. Santen licensed the development rights to DE-122 in the ophthalmic field from TRACON in 2014.

The discontinuance is not expected to have a material impact on Santen financial results in the fiscal year ending March 31, 2020.
