  • Participants are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, and other study procedures.
  • Patients with the ability to comprehend and sign the informed consent.
  • Written informed consent obtained prior to any screening procedures.
  • Subjects in good health with no baseline disease of any kind.

Exclusion criteria

  • Participants are not willing or able to comply with either: all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, or other study procedures.
  • Participants who are currently under medical follow-up for any medical condition or who are regularly taking medication for any condition.
  • Subject has experienced symptoms consistent with a respiratory infection within the 7 days prior to the administration of the investigational treatment.
  • Have a known history of human immunodeficiency virus infection, Hepatitis B or Hepatitis C; testing is not required in the absence of prior documentation or known history.
  • Have a known history of drug substance abuse.

Treatment and study plan

CD45RA- memory T lymphocytes cells sourced from healthy peripheral blood mononuclear cells male donors.

Other

CD45RA- memory T lymphocytes cells sourced from healthy peripheral blood mononuclear cells male donors. These cells will be administered intranasally.

Primary outcomes

  1. Safety and tolerability

    Time frame: 6 months

    Safety and tolerability will be evaluated based on the frequency and attribute of DLT (dose limiting toxicities) in the first 7 days after solution administration and the incidence of all AEs and serious adverse events (SAEs) during study period.

    The primary endpoint will be DLT, defined as any grade 3 or higher adverse event (as defined in the Common Terminology Criteria for Adverse Events (CTCAE) version 5) with an attribution of definitely or probably related to the product administration.

    The highest dose found safe in the present study will be determined as the maximum tolerated dose (MTD).

Secondary outcomes

  1. Persistence of donor cells in the nasal mucosa of participants post-administration of treatment cells

    Time frame: 6 months

    Persistence of donor cells in the nasal mucosa of participants post-administration of treatment cells, confirmed by the detection of male donor cells through nasopharyngeal aspirate and the presence of a Y chromosome.
