摘要:
The present invention relates to compositions for intradermal delivery of an antigenic or immunogenic agent in combination with one or more adjuvants. The immunogenic compositions of the invention comprise an antigenic or immunogenic agent and at least one adjuvant, which enhances the immune response to the antigenic or immunogenic agent, once delivered to the intradermal compartment of a subject's skin. The immunogenic compositions of the invention have enhanced efficacy as the adjuvants of the composition promote recruitment of antigen presenting cells to the intradermal compartment and thus enhance presentation and/or availability of the antigenic or immunogenic agent to the antigen presenting cells. The enhanced efficacy of the immunogenic compositions of the invention results in a therapeutically and/or prophylactically effective immune response after a single intradermal dose, with lower doses of adjuvant than conventionally used, achieving therapeutic efficacy from a single administration.
摘要:
The present invention relates to immunogenic compositions containing an immunogen and a specific combination of two or more traditional excipients. The excipients in the composition act in combination and enhance immune responses to the immunogen from a subject. The combination of excipients may be used as adjuvant in immunogenic compositions, regardless of route or target of delivery. The compositions can be administered, for example, intradermally, epidermally, transdermally, junctionally, nasally, or subcutaneously.

The present invention relates to immunogenic compositions for intradermal delivery of an antigenic or immunogenic agent in combination with one or more excipients. The immunogenic compositions of the invention comprise an antigenic or immunogenic agent and at least one excipient which acts as an adjuvant, i.e., enhances the immune response to the antigenic or immunogenic agent, once delivered to the intradermal compartment of a subject's skin. The immunogenic compositions of the invention comprise an excipient which when administered to the intradermal compartment of skin in accordance with the invention demonstrate adjuvant activity. The immunogenic compositions of the invention have enhanced efficacy as the excipients of the composition cause an asymptomatic skin irritation and recruit antigen presenting cells to the intradermal compartment and thus enhance presentation and/or availability of the antigenic or immunogenic agent to the antigen presenting cells. The enhanced efficacy of the immunogenic compositions of the invention may result in a therapeutically effective immune response after a single intradermal dose, with lower doses of antigenic or immunogenic agent than conventionally used, and without the need for booster immunizations
摘要:
A method and device for intradermal delivery of a reconstituted powdered medicament. The device includes a chamber, which is in fluid communication with a microdevice, e.g. microabrader or one or more microneedles. A cartridge containing the powdered medicament may be located within said chamber. At least one burstable membrane retains a powdered medicament within the housing. The method involves the steps of positioning the device at a delivery site on the skin of a patient and intradermally administering the medicament by dispensing a diluent from a diluent source an through inlet port to rupture the membranes, reconstitute the powdered medicament and deliver the reconstituted medicament through the microdevice to the dermal region of the skin.

摘要:
The present invention relates to formulations, methods and devices for delivering one or more biologically active agents, particularly a diagnostic or therapeutic agent to the intradermal compartment of a subject's skin. The present invention provides an improved method of delivery of biologically active agents in that it provides among other benefits, rapid uptake into the local lymphatics, improved targeting to a particular tissue, improved bioavailability, improved tissue bioavailability, improved tissue specific kinetics, improved deposition of a pre-selected volume of the agent to be administered. This invention provides methods for rapid transport of agents through lymphatic vasculature accessed by intradermal delivery of the agent. Methods of the invention are particularly useful for delivery of diagnostic and therapeutic agents. The invention relates to the synergy gained in diagnosing and treating disease when intradermal delivery and controlled release materials are combined. Specifically, the synergy is achieved when intradermal delivery is combined with lipid based particles.
摘要:
The present invention relates to dermal vaccine formulations, designed for targeted delivery of an immunogenic composition to a dermal compartment of skin including the intradermal and epidermal compartments. The dermal vaccine formulations of the invention comprise an antigenic or immunogenic agent, and at least one molecule, e.g., a chemical agent, which enhances the presentation and/or availability of the antigenic or immunogenic agent to the immune cells of the intradermal compartment or epidermal compartment resulting in an enhanced immune response. The dermal vaccine formulations of the invention have enhanced efficacy as the antigenic or immunogenic agent is delivered to the intradermal compartment or epidermal compartment with enhanced presentation and/or availability to the immune cells that reside therein. The enhanced efficacy of the dermal vaccine formulations results in a therapeutically effective immune response after a single intradermal or epidermal dose, with lower doses of antigenic or immunogenic agent than conventionally used, and without the need for booster immunizations.
