Neurocrine Biosciences announces initiation of Phase 1 clinical study evaluating NBIP-'2118, a corticotropin-releasing factor type 2 receptor agonist. PR Newswire Today at 4:30am PDT * NBIP-'2118 targets a new, non-incretin mechanism for weight loss with lean mass preservation SAN DIEGO, May 4, 2026 /PRNewswire/ - Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced the initiation of a Phase 1 first-in-human clinical study evaluating the safety and tolerability of NBIP-'2118 in adult participants. NBIP-'2118 is an investigational corticotropin-releasing factor type 2 receptor (CRF[2]) peptide agonist and a potential first-in-class therapy for obesity. "This program represents an important step in applying Neurocrine's expertise in CRF biology to treat metabolic disease," said Sanjay Keswani, M.D., Chief Medical Officer, Neurocrine Biosciences. "CRF[2] agonism is a promising and differentiated mechanism with the potential to address key limitations of existing therapies, including the loss of lean mass during weight reduction. We believe this program could play a meaningful role as both a standalone therapy and in combination with other mechanisms, including incretin-based approaches." The Phase 1 study initially will evaluate the safety and tolerability of single ascending doses of NBIP-'2118 compared to placebo in healthy-weight adult participants, as well as those who are overweight or obese. Initial data is expected in 2027. NBIP-'2118 is an internally discovered and investigational CRF[2] peptide agonist designed for once-weekly subcutaneous administration. In preclinical models, NBIP-'2118 demonstrated high selectivity and potency, with weight loss primarily driven by fat reduction while preserving or increasing lean mass, including skeletal muscle. By targeting CRF[2] to both reduce fat and preserve muscle, NBIP-'2118 could be particularly beneficial for patients at risk of muscle loss with a differentiated profile from existing therapies which often attribute a significant proportion of weight loss to lean mass. Neurocrine's integrated obesity strategy includes multiple programs in preclinical development. NBIP-'1968 is an internally discovered, investigational triple agonist targeting GLP-1, GIP, and glucagon receptors and is intended for use in combination with NBIP-'2118, with the goal of achieving greater weight loss while maintaining muscle-sparing benefits. Neurocrine is also advancing a single-molecule incretin mimetic-CRF[2] agonist conjugate. In addition, Neurocrine is developing a long-acting triple-agonist (targeting GLP-1, GIP, glucagon receptors) conjugated to an antibody Fc domain to extend half-life and potentially enable once-monthly or even less frequent dosing. About Obesity Obesity is a chronic disease characterized by excess body fat and is associated with serious health conditions, including type 2 diabetes, cardiovascular disease and certain cancers. It is driven by complex biological, environmental, and genetic factors - not simply lifestyle or willpower. Obesity has reached epidemic levels globally, affecting a significant portion of adults and placing a substantial burden on public health systems. Despite recent advances in treatment, there remains a need for additional therapies that support safe, effective and sustainable long-term weight management. About Neurocrine Biosciences, Inc.

Nxera Pharma's partner Neurocrine Biosciences doses first patient in Phase 2 trial of NBI-1117570 for adults with schizophrenia. GlobeNewswire | Nxera Pharma Today at 4:30pm PDT * NBI-1117570 is an investigational oral, dual muscarinic M1/M4 selective receptor agonist discovered by Nxera advancing through clinical development under a multi-program collaboration with Neurocrine * Nxera to receive US$22.5 million in milestone payments from Neurocrine Tokyo, Japan and Cambridge, UK, 13 April 2026 - Nxera Pharma Co., Ltd. ("Nxera" or "the Company"; TSE 4565) today announces that its partner Neurocrine Biosciences Inc. ("Neurocrine") has initiated and dosed the first patient(s) in a Phase 2 clinical study of NBI-1117570 ("NBI-'570") in adults with schizophrenia. As a result, Nxera will receive milestone payments of US$22.5 million from Neurocrine pursuant to the agreement. The milestone payments will be recognised as revenue in Q1 FY2026. NBI-'570 is an investigational, orally administered, dual muscarinic M1/M4 receptor agonist discovered using Nxera's proprietary NxWave(TM) drug discovery platform. Christopher Cargill, President and CEO of Nxera Pharma, commented: "The initiation of this Phase 2 study with NBI-'570, the second NxWave(TM)-designed compound in Neurocrine's muscarinic agonist portfolio to advance into Phase 2 clinical trials, represents another important step forward in our highly productive collaboration. Schizophrenia remains an area of significant unmet medical need and we believe NBI-'570 has the potential to contribute meaningfully to improving outcomes for patients. We look forward to sharing further updates on progress across the muscarinic agonist portfolio." The Phase 2 study (NCT07288333) is a double-blind, placebo-controlled trial designed to evaluate the efficacy, safety and tolerability of NBI-'570 in adult patients with schizophrenia requiring in-patient treatment. The study is expected to enroll approximately 120 patients. The primary endpoint is change from baseline in the Positive and Negative Syndrome Scale (PANSS) total score, and the key secondary endpoint is treatment-emergent adverse events (TEAEs). About NBI-1117570 NBI-1117570 is an investigational, oral, dual muscarinic M1/M4 agonist. Muscarinic receptors are fundamental to activating signaling pathways in the brain. There are five muscarinic acetylcholine receptors involved in neurotransmission, two of which are selectively targeted by NBI-'570 (M1 and M4), with M1 clinically validated as a potential drug target in cognition and M4 in psychosis. Neurocrine Biosciences acquired the rights to develop and commercialize NBI-'570 from Nxera Pharma. About Schizophrenia Schizophrenia is a serious and complex syndrome with heterogeneous symptoms. The World Health Organization estimates that the disorder impacts approximately 24 million people worldwide. Annual associated costs for schizophrenia are estimated to be more than $150 billion in the United States. As one of the leading causes of disability worldwide, it often results in significant emotional and functional burden for those who experience symptoms, as well as their family and friends. This chronic and disabling mental health condition is thought to result from a complex interplay of genetic and environmental risk factors. Traditional treatment approaches for schizophrenia rely on the use of antipsychotic medications that can lead to considerable short- and long-term health impacts.
