Cellectis Provides Business Objectives for 2022 and Updates its Corporate Presentation

January 4, 2022 - New York (N.Y.) - Cellectis (Euronext Growth: ALCLS - Nasdaq: CLLS), a clinical-stage biotechnology company using its pioneering gene-editing platform to develop life-saving cell and gene therapies, reported business objectives for its products pipeline and in-house manufacturing for 2022.

“In 2022 we will be focusing on pursuing recruitments into our core ongoing clinical trials BALLI-01, AMELI-01, MELANI-01 and on filing an investigational new drug application (IND) for the first dual allogeneic UCART20x22.” said Dr André Choulika, CEO of Cellectis. “Furthermore, we are on-track to start dosing patients with our in-house manufactured investigational medicinal products (IMPs) during 2022. Our two manufacturing sites in Raleigh, NC and Paris, France are now fully operational. This focus allows us to extend our cash runway (excluding our subsidiary Calyxt, Inc.) into early 2024.”

Cellectis 2022 expected milestones:

• UCART22 is an allogeneic CAR-T cell product candidate targeting CD22 being evaluated in patients with relapsed or refractory B cell acute lymphoblastic leukemia (r/r B-ALL) in the BALLI-01 Phase 1, multi-center dose-escalation clinical study.

AMELI-01 (for UCART123)

• Cellectis targets to enroll patients at Dose Level 2 (DL2) and eventually escalate to higher dose levels with FCA preconditioning regimen.
