Previous wording

We are a clinical-stage biopharmaceutical company pioneering the discovery and development of a new class of RNA-based therapeutics with the goal of upregulating gene expression and restoring healthy protein levels to treat a broad range of genetic diseases. Regulatory RNAs (“regRNAs”) play a central role in the regulation of every protein-coding gene by contributing to gene activation and suppression. Our approach is designed to amplify messenger RNA (“mRNA”) expression by harnessing the power of regRNAs that form localized complexes with transcription factors and regulate gene expression. Our proprietary RNA Actuating Platform, or RAP Platform, allows us to rapidly and systematically identify and characterize the active regulatory elements controlling every expressed gene and tens of thousands of druggable enhancer and promoter regRNA sequences that control protein-coding genes. Once a disease-associated target gene is identified, we apply our RAP Platform to identify the controlling regRNA and rapidly generate novel antisense oligonucleotide (“ASO”) candidates, which we also refer to as RNA Actuators. These ASOs are designed to bind to the identified regRNA and amplify the expression of the target gene in a specific and controllable way. We are currently focused on metabolic diseases and diseases of the central nervous system with validated disease biology, and we believe our RAP Platform allows us to address a broad range of rare and prevalent genetic diseases in which a modest increase in protein expression has the potential to be clinically meaningful.

We are also leveraging our RAP Platform to advance a preclinical program for the treatment of synaptic Ras GTPase activating protein 1 (“SYNGAP1”)-related disorders, a group of neurodevelopmental conditions caused by pathogenic variants in the SYNGAP1 gene that result in a haploinsufficient state, reducing SYNGAP protein levels by up to 50%. SYNGAP plays a critical role in cognitive development and synaptic function. Epilepsy is a common characteristic of these disorders and nearly all patients experience some degree of developmental delay and cognitive impairment. Incidence estimates vary significantly, ranging from one to 40 per 100,000 individuals. While we believe that SYNGAP1-related disorders remain underdiagnosed, we estimate that there are approximately 10,000 individuals living with these disorders in the United States. SYNGAP1-related disorders are reported to represent 0.5% to 1.0% of all intellectual disability cases, making them among the most common causes of intellectual disability in patients with epilepsy, and indicating that the patient population may be significantly larger than incidence estimates suggest. There are no FDA-approved, disease-modifying therapies for SYNGAP1-related disorders. Treatment is often limited to supportive physical, occupational and speech therapy. A combination of non-specific anti-seizure medications may be prescribed, though SYNGAP1-related disorders have proven difficult to control with available therapeutics. Up to 50% of patients do not adequately respond to medication, in which case implantable devices, such as those for vagus nerve stimulation, may offer incremental therapeutic benefit. We are advancing our CMP-SYNGAP program to address the significant unmet need by targeting the direct cause of SYNGAP1-related disorders, haploinsufficiency, which we believe is amenable to targeting through regRNAs. Our CMP-SYNGAP program is a novel approach that targets the SYNGAP1 gene at the transcriptional level to restore SYNGAP function and improve symptoms by utilizing an intrathecally delivered ASO. Upregulation of SYNGAP1 gene expression may increase SYNGAP protein levels in amounts sufficient to yield therapeutic benefit. Our preclinical studies demonstrated a dose-dependent increase in SYNGAP1 mRNA levels accompanied by a reduction in SYNGAP1 expression. We have nominated a development candidate, CMP-SYNGAP-01, and expect to initiate GLP toxicology studies in 2025 to enable the filing of a clinical trial application. We also plan to present new preclinical data in an oral presentation at the 28th American Society of Gene and Cell Therapy Annual Meeting on May 16, 2025, demonstrating a meaningful increase in SYNGAP1 protein levels following intrathecal administration of CMP-SYNGAP-01 in non-human primates.

Previous wording

Based on our preclinical studies, we believe our clinical product candidate, CMP-CPS-001, has the potential to be the first disease-modifying therapy for the treatment of the most prevalent urea cycle disorders (“UCDs”). UCDs are a group of severe, inherited metabolic diseases caused by mutations in the genes that encode one or more of the eight enzymes and transporters necessary to convert ammonia into urea. The inability of the body to properly metabolize ammonia leads to the accumulation of toxic levels in circulation, ultimately resulting in severe health outcomes, such as neurologic disability, seizure and death. CMP-CPS-001 is designed to improve urea cycle activity by amplifying expression of carbamoyl phosphate synthetase 1 (“CPS1”), an enzyme that catalyzes the first step of the urea cycle, by binding to a CPS1-specific regRNA. Our preclinical studies have demonstrated that modulating the activity of the target regRNA increases expression of the CPS1 gene, resulting in increased CPS1 enzyme levels, which allows for more ammonia to be converted into urea, thereby lowering ammonia levels to normal, healthy ranges. These preclinical studies also demonstrated that CMP-CPS-001 can increase the level of, or upregulate, the production of multiple enzymes responsible for converting ammonia into urea, potentially allowing us to address more than 85% of patients with UCDs. We are evaluating CMP-CPS-001 in an ongoing Phase 1 clinical trial in healthy volunteers and have completed a planned interim analysis of safety and pharmacokinetic data from all four cohorts of the single ascending dose (“SAD”) portion of the clinical trial, from which no safety trends of concern were observed. We have also completed dosing of the first three cohorts from the multiple ascending dose (“MAD”) portion of the clinical trial. We expect to report data from the SAD and MAD portions of the clinical trial, including safety, pharmacokinetic and key pharmacodynamic biomarker data, in the fourth quarter of 2025. We have also submitted a clinical trial application in Europe for a Phase 1b expansion to enroll female participants who are heterozygous for a mutation of the OTC gene, pending regulatory clearance. We estimate that there are approximately 2,000 diagnosed female OTC heterozygotes in the United States who have inherited one copy of a gene with OTC-related changes and experience potentially addressable UCD symptoms.
