September 16, 2014 — Paris (France) — Cellectis (Alternext: ALCLS.PA), a leader in the development of adoptive immunotherapies based on engineered allogeneic CART cells (UCART) has hosted an R&D/ Analyst Day on September 11 in New York City.

This meeting was intended to explain shareholders and investors Cellectis’ research and development. More than 100 people attended that public event at which Cellectis’ scientists provided an overview of the Company's therapeutic innovations with feature presentations by key opinion leaders: Pr. Laurence Cooper, MD Anderson Cancer Center; Dr. Jaume Pons Senior Vice President and CSO of Rinat, the biotech unit of Pfizer and Eric Falcand, Director, Alliance Management & US Licenses at Servier. The meeting started at 8:00 a.m. and ended after a Q&A session at noon.

Summary of the event

After a welcoming remarks by Dr. André Choulika, Ph.D., Chairman and CEO of Cellectis, the meeting opened with a keynote address by Pr. Laurence Cooper, MD, Ph.D., University of Texas, MD Anderson Cancer Center, who discussed the clinical and economic benefits of immuno-oncology area and demonstrated the apparent benefits of an allogeneic approach to undertake off-the-shelf T-cell therapy for patients.

Dr. Philippe Duchateau, Ph.D., Chief Scientific Officer, then presented the Company’s skills and know-hows, Dr. Julien Valton, Ph.D., Innovation Project Leader, explained how Cellectis has fully matured TALENTM technology that is considered as one of the most precise, efficient and the safest genome editing method today.

Dr. Laurent Poirot, Ph.D., Head of Early Discovery, highlighted how Cellectis has developed unmatched capabilities for engineering T cells to fit the therapeutics needs of multiple cancer indications and how traits can be built into T cells to overcome tumor immune evasion.

Dr. Jaume Pons, Ph.D., Senior Vice President and Chief Scientific Officer of Rinat, the biotech unit of Pfizer, described Cellectis and Rinat/Pfizer’s partnership as a scientific and cultural match aiming to produce ‘Off-the-Shelf’ therapies.
