  • Publication number: 20230085357
    Abstract: The present invention provides compositions comprising one or more active pharmaceutical ingredients, wherein the compositions are in the form of high solids concentration pastes capable of being injected in relatively low volumes into an animal using standard commercially available syringes. The invention also provides methods of making such compositions, particularly those compositions comprising high molecular weight active ingredients (e.g., antibodies, enzymes and other proteins and peptides) at relatively high therapeutic concentrations in the high solids concentration pastes. The invention further provides methods of using such formulations in treating, preventing and/or ameliorating certain diseases and physical disorders in animals, including humans, in need thereof. The invention also provides kits comprising the formulations of the invention and a suitable syringe, which in some aspects may be pre-loaded or pre-filled with a composition of the invention.

  • Publication number: 20230001114
    Abstract: A dry powder inhaler includes a powder storage element configured to hold a powdered medicament and an inlet channel receives, powdered medicament from the powder storage element that is entrained in an airflow. The inlet channel has a first diameter and defines an opening. The inhaler includes a dispersion chamber that receives the airflow and the powdered medicament from the opening. The dispersion chamber has a second diameter. The inhaler includes an actuator housed within the dispersion chamber. The actuator oscillates within the dispersion chamber when exposed to the airflow to deaggregate the powdered medicament entrained by the airflow passing through the dispersion chamber. A ratio between the first diameter and the second diameter is between about 0.40 and 0.60 such that an audible sound is produced as the actuator oscillates. The inhaler includes an outlet channel through which the airflow and powdered medicament exit the inhaler.

  • Patent number: 11129940
    Abstract: This disclosure includes syringes, kits containing the same, and related methods. Some syringes are pre-loaded with paste and have a syringe body defining a reservoir having an internal first transverse dimension, a paste disposed within the reservoir, the paste having a solids concentration of greater than 50 mg/mL, a needle defining a lumen having an internal second transverse dimension that is smaller than the first transverse dimension, the needle configured to be in fluid communication with the reservoir to allow intracutaneous delivery of the paste, and a plunger and/or piston disposed within the reservoir and configured to be moved to dispense paste from the reservoir through the lumen. Some syringes include a fitting (e.g. Luer fitting) disposed on the syringe body and in fluid communication with the reservoir and a sealing cap disposed on the Luer fitting to seal the reservoir.
