Promising Advancement in Autoimmune Disease Treatment: Jacobio’s JAB-8263 Clears Regulatory Hurdle for Clinical Trials
New York, NY – July 3, 2025 – Jacobio Pharmaceuticals, a clinical-stage biopharmaceutical company, announced today that its Investigational New Drug (IND) application for JAB-8263, a novel BET inhibitor, has been accepted by the U.S. Food and Drug Administration (FDA) for a Phase I/II clinical trial. This significant milestone paves the way for the evaluation of JAB-8263 as a potential treatment for patients suffering from various autoimmune diseases.
The acceptance of the IND application signifies that the FDA has reviewed the preclinical data and manufacturing information for JAB-8263 and has determined that it is safe to proceed with human clinical testing. This is a critical step forward in the drug development process, bringing Jacobio closer to potentially offering a new therapeutic option for individuals with debilitating autoimmune conditions.
JAB-8263 is a potent and selective inhibitor of the BET (Bromodomain and Extra-Terminal) protein family. These proteins play a crucial role in gene regulation, and their dysregulation has been implicated in the pathogenesis of numerous autoimmune diseases. By targeting the BET proteins, JAB-8263 aims to modulate the inflammatory and immune responses that drive these conditions.
“We are delighted by the FDA’s acceptance of our IND for JAB-8263,” said Dr. Li Zhang, Chief Medical Officer at Jacobio Pharmaceuticals. “This represents a significant step forward in our mission to develop innovative treatments for patients with unmet medical needs. We are eager to initiate the Phase I/II clinical trial and explore the potential of JAB-8263 to effectively manage the underlying mechanisms of autoimmune diseases.”
The upcoming Phase I/II clinical trial will be a first-in-human study designed to assess the safety, tolerability, and pharmacokinetics of JAB-8263 in healthy volunteers and patients with autoimmune diseases. The trial will also aim to gather preliminary evidence of efficacy by evaluating the drug’s impact on relevant biomarkers and clinical outcomes. The specific autoimmune diseases to be investigated in this trial are expected to be announced shortly.
Autoimmune diseases, such as rheumatoid arthritis, lupus, and multiple sclerosis, occur when the body’s immune system mistakenly attacks its own healthy tissues, leading to chronic inflammation and organ damage. Current treatment options often focus on broad immunosuppression, which can carry significant side effects. The targeted approach of JAB-8263 offers the potential for a more precise and potentially safer way to rebalance the immune system.
Jacobio Pharmaceuticals has a robust pipeline of innovative drug candidates and a strong commitment to advancing the development of novel therapies. The company’s focus on targeting key cellular pathways involved in disease progression positions them as a promising player in the biopharmaceutical landscape.
The initiation of this clinical trial marks a pivotal moment for Jacobio and, more importantly, for the patients who stand to benefit from new and effective treatments for autoimmune diseases. The company looks forward to sharing updates on the progress of the JAB-8263 clinical program as it advances.
