- Indapta Therapeutics, INC.
- Brief Summary
This is an open label, Phase 1b, multiple ascending dose, and dose-expansion study of IDP-023 administered in combination with interleukin-2 (IL-2) and ocrelizumab to evaluate the safety, tolerability, and biologic activity on autoreactive immune cells in patients with refractory progressive multiple sclerosis.
- Detailed Description
IDP-023 is an off-the-shelf product made from allogeneic g-natural killer (NK) cells, which are a natural subset of NK cells that develop over the course of an immune response in people who have been exposed to the human cytomegalovirus (HCMV). These cells may be particularly effective at targeting and killing the cells that cause the immune system to attack...
