Our Shielded Living Therapeutics^TM platform combines advanced cell engineering with innovations in biocompatible materials, potentially enabling our products to produce a wide range of therapeutic molecules that may be missing or deficient in the body, including proteins, antibodies and enzymes.

Our pipeline currently spans three disease areas – including rare blood, lysosomal, and endocrine diseases – with product candidates designed to be off-the-shelf, durable, controllable and redosable, without requiring modification of the patient’s genes or immunosuppression.

Based on earlier preclinical data, we believe that SIG-001, our lead product candidate, has the potential to prevent bleeding episodes in patients with moderate-severe to severe hemophilia A by continuously secreting human FVIII. We are currently enrolling patients in a Phase 1/2 trial in this indication, as we continue to advance our other programs toward the clinic.
