Cullinan Therapeutics shares rose in premarket trading Monday after the company reported that preliminary data showed its experimental T-cell engager produced encouraging clinical responses in lupus and rheumatoid arthritis patients.
Shares traded 9.6% higher ahead of the morning bell at $14.81.
The clinical-stage biopharmaceutical said a single dose of its CD19xCD3 T-cell engager, called CLN-978, led to clinical improvements and even remissions in patients with hard-to-treat lupus and rheumatoid arthritis.
A CD19xCD3 T-cell engager is a type of next-generation immune therapy designed to force T-cells to kill B-cells, the kind that sustain autoimmune diseases like lupus and rheumatoid arthritis.
Cullinan said that the early results showed deep, dose-dependent B-cell depletion and a safety profile that it said supports further clinical development.
"We are focused on advancing CLN-978 rapidly through global clinical development to accelerate bringing this new therapeutic option to patients," Chief Medical Officer Jeffrey Jones said.
