Full Press Release Details
CAMBRIDGE, Mass., Sept. 16, 2024 (GLOBE NEWSWIRE) -- Cullinan Therapeutics, Inc. (Nasdaq: CGEM), a biopharmaceutical company focused on developing modality-agnostic targeted therapies, today shared that it has submitted an Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) to evaluate its CD19xCD3 bispecific T cell engager, CLN-978, for the treatment of systemic lupus erythematosus (SLE).
“We are pleased to take the next step to advance our global study of CLN-978 in SLE in the U.S.,” said Jeffrey Jones, MD, MBA, Chief Medical Officer, Cullinan Therapeutics. “The Centers for Disease Control and Prevention (CDC) estimates SLE impacts more than 160,000 people in the U.S., and currently available treatments do not routinely induce treatment-free remission, with most patients requiring lifelong immune suppression that treats symptoms without modifying the course of disease. We are committed to developing new and better treatment options and are focused on advancing CLN-978, a novel, highly potent, half-life extended CD19xCD3 bispecific T cell engager that could offer a potentially disease-modifying, off-the-shelf option for patients.”
CLN-978 is a novel, highly potent, half-life extended CD19xCD3 bispecific T cell engager construct. CLN-978 potently triggers redirected lysis of CD19-expressing target cells in vitro and in vivo. CLN-978 is engineered to achieve very high affinity binding to CD19 to efficiently target B cells expressing very low CD19 levels. A human serum albumin (HSA)-binding domain increases the serum half-life of CLN-978 and, with subcutaneous delivery, permits more patient-friendly dosing and potentially reduced toxicity. CLN-978 contains two single-chain variable fragments, one binding with very high affinity to the CD19 target and the other binding to CD3 on T cells, and a single-domain antibody binding to HSA. CLN-978 was developed by an internal Cullinan team and is a wholly owned asset. CLN-978 has the potential to offer a convenient, off-the-shelf therapeutic option for patients with autoimmune diseases such as SLE and rheumatoid arthritis.
About Systemic Lupus Erythematosus (SLE)
SLE is a chronic, heterogeneous autoimmune disease in which the immune system attacks a patient’s own tissues. The most common manifestations of SLE include skin rashes, arthritis, swelling in the feet, and around the eyes, extreme fatigue, and low fevers. Lupus nephritis (LN) is a kidney disease and the most common severe manifestation of SLE. Approximately 40% of patients with SLE develop LN, which has a 10-year 30% mortality rate. SLE is more prevalent in women, people of color, and women of childbearing age. The CDC estimates the prevalence of SLE in the U.S. to be approximately 160,000 to 320,000 cases. Currently available treatments do not routinely induce treatment-free remission, and most patients require lifelong immune suppression that treats symptoms without modifying the course of disease.
