  • Publication number: 20260108531
    Abstract: The present invention relates to methods of treating hypogonadism in a male subject through administering intranasally to the male subject an intranasal testosterone bio-adhesive gel formulation to deliver a therapeutically effective amount of testosterone. In particular, the testosterone therapy of the invention remains effective if an allergic rhinitis event occurs in the male during the treatment or when the male subject uses a topical nasal vasoconstrictor or a topical intranasal decongestant during the hypogonadism treatment. Further, the present invention relates to a method of preventing Hie occurrence of an allergic rhinitis event in a male, who is undergoing a hypogonadism treatment with an intranasal testosterone bio-adhesive gel. In certain embodiments, the intranasal testosterone bio-adhesive gel formulation according to the invention comprises 4.0% and 4.5% testosterone.

  • Publication number: 20240342678
    Abstract: The present invention provides methods, systems and kits for performing microwell analysis in sealed small volumes. The microwells of the invention are sealed through the pairing of microwell and bead geometry wherein the diameter of the beads is greater than the diameter of the bottom of the microwells. Loading the beads into the microwells seals samples within an analytical space between the bottom of a nested bead and the bottom of the subject microwell.
