Our Pipeline
Therapeutic Programs
15-LO Inhibitor
Our lead therapeutic candidate, CU-13001, is designed to inhibit 15-lipoxygenase (15-LO). In preclinical studies, by inhibiting 15-LO, CU-13001 significantly reduces the production of 4-HNE, thus reducing LRRK2 kinase hyperactivity and α-synuclein aggregation in both genetic and idiopathic forms of PD.
Support for the role of this pathway in PD pathology was recently published in Science Translational Medicine1. Additional publications and the filing of an Investigational New Drug (IND) application for CU-13001 are expected in 2025. This will allow us to begin clinical studies in healthy adult volunteers, followed rapidly by studies in PD patients.
Selective CaV3.2 Antagonist
Acurex has discovered a first-in-class selective antagonist of the CaV3.2 voltage-gated calcium channel that can serve as a starting point for finding a lead drug candidate. This channel plays a significant role in Parkinson’s disease and other pathologies by dysregulating calcium balance in the cell2,3. In PD, calcium dysregulation leads to mitochondrial stress, neuroinflammation, and dopaminergic deficits, ultimately resulting in neurodegeneration. Due to the wide-ranging impact of CaV3.2 in neurons, this program may offer symptomatic relief and potentially slow or stop neurological disease pathologies. Acurex plans to optimize a lead drug candidate over the next several months for eventual preclinical and clinical development.
T-Type Calcium Channel Inhibitor
Voltage-gated calcium channels have been targets of interest for CNS indications due to their role as essential regulators of neural communication4–8. T-type calcium channels are the only low-voltage activated calcium channels and play a key role regulating calcium oscillations and neuronal excitability. Acurex has developed a best-in-class pan T-type antagonist, CU-00048, that is highly selective to T-type calcium channels, has excellent drug-like properties, and is ready for IND-enabling studies. Acurex plans to partner this program for further development.
