Cellectis S.A. develops gene-edited cell and gene therapies as a clinical-stage biotechnology company. Its recurring news centers on allogeneic CAR T immunotherapies in oncology, including off-the-shelf, gene-edited CAR T-cell product candidates, and on broader gene therapy research using its gene-editing platform and in-house manufacturing capabilities.

Cellectis (CLLS) approved a strategic transformation on September 11, 2026 to focus on becoming an in vivo gene editing company targeting chronic metabolic diseases.
The company will prioritize two lead programs: .HEAL-101, a base-editing therapy targeting APOC3 for severe hypertriglyceridemia, and .HEAL-201, an epigenetic editing therapy targeting PCSK9 for severe hypercholesterolemia. Both are delivered via lipid nanoparticles and have shown high on-target activity and substantial APOC3 or PCSK9 reductions, as well as triglyceride lowering in humanized murine models. Phase 1 investigator-initiated trials in China are planned, with preliminary data expected in H2 2027 for .HEAL-101 and H1 2028 for .HEAL-201.
Cellectis will exit internal development of lasme-cel and eti-cel, seek partners for these assets, support existing cell therapy partnerships, and realign operations to extend its cash runway into H2 2028.
