Tharimmune, Inc. (NASDAQ:THAR) ("Tharimmune" or the "Company"), a clinical-stage biotechnology company developing a portfolio of therapeutic candidates in inflammation and immunology, received positive feedback from a Scientific Advice meeting with the European Medicines Agency (EMA) that included guidance on a planned Phase 2 trial to advance TH104, the Company's lead clinical-stage candidate for moderate-to-severe pruritus in primary biliary cholangitis (PBC).
The EMA interactions specifically focused on both the Phase 2 and Phase 3 clinical program of TH104. Overall, the Agency noted that using Article 10(3), hybrid application, is acceptable and could enable referring to non-clinical and some safety data from the approved products. Regarding non-clinical information provided, the Agency endorsed the strategy presented by the Company and noted that there is no need to conduct additional animal studies and considered human exposure to be adequate to move forward. The Agency found the design and main features of the proposed Phase 2 study overall acceptable with some comments. The Agency also provided general guidance for the design of a future Phase 3 study.
"We are pleased with our interactions with both the FDA and EMA," said Randy Milby, CEO of Tharimmune. "The recent regulatory feedback from the EMA builds on the previous positive interactions with the FDA while providing a roadmap for TH104 for chronic pruritus in PBC, which continues to be a debilitating symptom for patients suffering from this rare condition. The progress with regulatory agencies is a testament to our continued commitment to advance innovative solutions in inflammation and immunology."
The Company plans to initiate a Phase 2 multiple-ascending dose trial in the coming months to assess the safety and tolerability of TH104, which will also assess the change from baseline in itch scores to evaluate chronic pruritus in PBC patients. The Company expects topline data in 2025 and continues to engage with both U.S. and EU regulatory authorities.
About TH104
TH104 is embedded with nalmefene onto a proprietary transdermal buccal film that adheres to the inside of the mouth. TH104 is a product candidate for multiple liver-related and other pruritogenic inflammatory conditions. The molecule has a dual mechanism of action affecting both the µ-opioid receptor and the kappa-opioid receptor, as well as potentially inhibiting IL-17 inflammatory cytokine expression. These opioid receptors when stimulated and/or inhibited by the body's natural ligands have been known to be involved in the body's itch circuitry.
About Pruritus and Primary Biliary Cholangitis
According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of the National Institutes of Health, PBC is a chronic disease where the bile ducts in the liver eventually become dysfunctional and cause the buildup of bile, resulting in liver damage. The disease, believed to be an autoimmune condition, affects an estimated 58 out of every 100,000 U.S. women and about 15 out of every 100,000 U.S. men. Pruritus is one of the most common conditions associated with PBC, affecting up to 75% of individuals at some point during their disease course. It has a negative impact on health-related quality of life with limited treatment options. Published survey data of PBC respondents suffering from pruritus described their itch as "bugs crawling under the skin." More than 65% of patients reported that the itch was worse at night, known as nocturnal pruritus, a high unmet need.
About Tharimmune
Tharimmune, Inc. is a clinical-stage biotechnology company developing a diverse portfolio of therapeutic candidates in immunology and inflammation. The lead clinical asset, TH104, aims to suppress chronic pruritus associated with primary biliary cholangitis (PBC), a rare autoimmune liver disease with no known cure. The expanded pipeline includes TH023, an oral TNF-alpha inhibitor, offering a new approach to treating autoimmune diseases. Tharimmune is also advancing early-stage multi-specific biologics targeting unique epitopes against multiple solid tumors. The company has a license agreement with OmniAb, Inc. to access their antibody discovery technology for targeting specified disease markers.
