Overview
Randomized, double-blinded, placebo-controlled trial to determine the safety and efficacy of CYR-064.
Description
The purpose of this study is to determine the safety and effectiveness of CYR-064 in a randomized, double-blinded, placebo-controlled trial to determine the safety and efficacy of CYR064.
The study will take approximately 32 weeks which will include a 4-week screening period to evaluate if participants are right for the Study, followed by a 24-week Treatment Period, and a 1 week follow up after participants have completed the Study. About 150 subjects will participate in this study in about 25 research sites in the United States.
Eligibility
Inclusion Criteria:
- Able to provide written informed consent.
- Male or female 18-65 years of age.
- Endoscopy of the nasal cavity showing no structural or pathologic issues leading to hyposmia (nasal polyps, sinusitis, infection, etc.) that in the opinion of the Investigator, believes would hinder the delivery of study drug to the olfactory receptors.
- CT scan of the nasal cavity after the onset of hyposmia (within prior 2 years) prior to Baseline showing no structural or pathologic issue leading to hyposmia that in the opinion of the Investigator, believes would hinder the delivery of study drug to the olfactory receptors.
- Willing and able to self-administer the study drug, follow the study drug administration instructions, comply with study procedures, and participate in the scheduled study visits specified in this protocol.
Exclusion Criteria:
- History of traumatic brain injury, Parkinson's disease, early dementia, Alzheimer's disease, or any other condition in which hyposmia is not expected to improve in the opinion of the Investigator, such as history of congenital or idiopathic hyposmia or a surgical procedure that led to hyposmia.
- History of surgery that led to hyposmia.
- Concomitant Medical Conditions
- Current symptoms or signs of an acute respiratory viral illness at Screening or Baseline.
- Chronic viral infection or immunodeficiency condition (e.g., medical history of human immunodeficiency virus) based on medical records.
- Any active malignancy.
- Any concomitant medical condition that in the opinion of the Investigator, compromises patient safety or compliance with the study protocol or collected data.
- History of moderate to severe Substance Use Disorder within the past 3 years as assessed by the Investigator.
- History of persistent chronic sinusitis without polyps or chronic sinusitis with polyps.
- Use or planned use of tobacco or nicotine-containing products, including smoking, smokeless tobacco, e-cigarettes, or nicotine replacement products within 3 months prior to Screening through EOS.

- Use or planned use of another investigational drug within 4 weeks prior to Screening through Follow-Up.
- Receiving any concomitant medication/therapy that would, in the opinion of the Investigator, compromise patient safety or compliance with the study protocol or collected data.

Vulnerable patients. Any condition or abnormality (including clinical laboratory, physical
examination, or vital sign abnormalities), current or past, that, in the opinion of the
Investigator, would compromise the efficacy evaluation, safety of the patient, or would
