About this study

This is a Phase 1/2 study to evaluate the safety and tolerability of 18F-OP-801 in subjects with ALS, AD, MS, PD and age-matched HVs. 18F-OP-801 is intended as a biomarker for PET imaging of activated microglia and macrophages in regions of neuroinflammation.

Sponsor: Ashvattha Therapeutics, Inc.

You may qualify if…

  • 1. Has the ability to understand and sign the written ICF and local medical privacy authorization forms, which must be obtained prior to the conduct of any study related procedures.
  • 2. Female subjects of non-childbearing potential must be either surgically sterile (hysterectomy, bilateral tubal ligation, salpingectomy, and/or bilateral oophorectomy at least 26 weeks before the Screening Visit) or postmenopausal, defined as spontaneous amenorrhea for at least 2 years, with follicle-stimulating hormone (FSH) in the postmenopausal range at screening, based on the local laboratory's defined ranges.
  • 3. Female subjects of childbearing potential (i.e., ovulating, premenopausal, and not surgically sterile) and all male subjects must agree to practice abstinence from sexual intercourse or use a medically accepted contraceptive regimen (including hormonal contraceptives) during their participation in the study and for 90 days (males) or 6 months (females) after Day 1. Medically accepted contraceptive methods are defined as those with 90% or greater efficacy and are as follows:
  • 1. Male subjects: condoms or surgical sterilization of subject at least 26 weeks before the Screening Visit (i.e., vasectomy).
  • 2. Female subjects:
  • 1. Surgical sterilization at least 26 weeks before the Screening Visit (includes hysterectomy or bilateral tubal ligation, bilateral oophorectomy, or salpingectomy);
  • 2. Intrauterine device or diaphragm with spermicide for at least 12 weeks before the Screening Visit; or
  • 3. Hormonal contraception (oral, implant, injection, ring, or patch) for at least 12 weeks before the Screening Visit.

You may not qualify if…

  • 19. Clinical signs or laboratory findings suggestive of neuromyelitis optica (NMO) spectrum disorders or myelin oligodendrocyte glycoprotein (MOG)-associated encephalomyelitis (i.e., presence of anti-NMO \[aquaporin-4\] antibodies or anti-MOG antibodies)
  • 20. Diagnosis of progressive multifocal leukoencephalopathy (PML)
  • 21. Secondary, atypical, or genetic parkinsonism
  • 22. Clinically relevant finding on physical examination at Screening
  • 23. Family history of neurological disease that may confound interpretation of imaging results
  • 24. History of any central nervous system disorder or brain trauma that could cause imaging abnormalities in the opinion of the Principal Investigator and Medical Monitor
