Transgene Provides Update on Timing of Upcoming Milestone for TG4010

Regulatory News:

Transgene S.A. (Paris:TNG) today provided an update on the expected timing for a key milestone event for one of its lead cancer immunotherapy programs, TG4010 MUC-1 targeted immunotherapy. The Company reported that the number of disease progression events required per protocol to perform the progression-free survival (PFS) analysis for the Phase 2b part of the TIME study evaluating TG4010 in lung cancer was reached later than expected. This has resulted in a delay in the time to topline data, now expected early in the first quarter of 2014 instead of the fourth quarter of 2013.

"We look forward to reporting topline clinical data from the TIME trial in lung cancer with TG4010 early in the new year” said Philippe Archinard, Chairman and CEO of Transgene. "It is an exciting time for Transgene as we make plans for this important program and our other clinical-stage immunotherapeutics”.

About TG4010

TG4010 is a novel MUC-1 targeted immunotherapy. The TIME trial is a randomized, placebo-controlled, global Phase 2b/3 trial evaluating TG4010, a novel MUC-1 targeted immunotherapy, in combination with chemotherapy in patients with Stage IV MUC-1 positive non-small cell lung cancer. The Phase 2b part of the study is ongoing, with the objective of validating a predictive biomarker for efficacy (PFS). If confirmed, this biomarker would enable selection of the patient population for the Phase 3 portion of study.

Transgene has signed an exclusive option agreement with Novartis for the development and commercialization of TG4010 for the first-line treatment of NSCLC and other potential cancer indications. Following receipt of the report on the results of the Phase 2b part of the TIME trial, Novartis has 90 days to decide if it will exercise its option to TG4010.
