Embodiment Construction

[0119] figure 1 Shown is the interior of a drug delivery device 1 comprising a primary drug delivery assembly 2 and a secondary drug delivery assembly 3 held in a housing 4 indicated only with reference numeral 4 . The primary drug delivery assembly 2 is used to deliver the primary medicament contained in the primary cartridge 5 . The secondary drug delivery assembly 3 is used to deliver the secondary drug contained in the secondary cartridge 6 . The cartridge may also be held in a cartridge holder attachable to the distal end of the device 1 . The cartridge holder for the cartridge may be integrated in a single cartridge holder hub.

[0120] On the distal end of the assembly a 2 to 1 pin adapter 7 is attached. On the distal end 8 of the needle adapter 7 a thread is formed. An injection needle can be attached to the thread or injection. The injection needle is in fluid communication with two needles in the needle adapter 7 pointing in the proximal direction, which penetra...

Abstract

Drug delivery device (1) comprising a housing (4) retaining a primary drug delivery assembly (2) for the delivery of a primary medicament with a primary dose setting member configured to rotate in a helical movement to set a dose of the primary medicament and a secondary drug delivery assembly (3) for the delivery of a secondary medicament. A dose dial (12) is movable between a first position anda second position in axial direction and is rotationally constrained with respect to the housing (4) when moved from the first position into the second position and is rotationally constrained to theprimary dose setting member in the second position for setting a dose of the primary medicament. A secondary drive sleeve (16) of the secondary drug delivery assembly (2) serves for dispense of the secondary medicament. The dose dial and the secondary drive sleeve can be coupled for dose setting.

Description

technical field [0001] The present invention relates to a drug delivery device for injecting two or more medicaments from separate medicament cartridges, having a primary drug delivery assembly and a secondary drug delivery assembly. Background technique [0002] Some disease states require treatment with one or more different agents. Some drug compounds need to be delivered in a specified relationship to each other to deliver an optimal therapeutic dose. Here, combination therapy may be desirable but not possible in a single formulation because of, for example but not limited to, stability, compromised therapeutic performance and toxicology. [0003] For example, in some instances, treatment of diabetes with long-acting insulin and glucagon-like peptide-1 (GLP-1 ) derived from the transcript of the proglucagon gene may be beneficial. GLP-1 is found in vivo and is secreted by intestinal L cells as a gut hormone. GLP-1 has several physiological properties that make it (and...
