In the exemplary embodiment, the medicament container 20 includes a barrel 22, a stopper 24 slidably disposed in the barrel 22 and a needle 26 coupled to a distal end of the barrel 22. In an exemplary embodiment, the stopper 24 may be made from a rubber material. A proximal end of the barrel 22 includes a flange 28 which may be fully or partial circular, elliptical, square, rectangular or any other shape. The barrel 22 may be any size (e.g., 0.5 ml, 1 ml, 2 ml, etc.) and be made of any suitable material (e.g., plastic, glass). In an exemplary embodiment, the barrel 22 may be manufactured from Type I clear glass. In an exemplary embodiment, the stopper 24 is made from a rubber material. In an exemplary embodiment, the needle 26 is made from stainless steel. The needle 26 may be any gauge or length.

(15) In an exemplary embodiment, a needle shield 29 may be removably coupled to the distal end of the barrel 22 to cover the needle 26. In an exemplary embodiment, the needle shield 29 may be a sheath 29.1 made of, for example, rubber or elastomer latex. In another exemplary embodiment, the needle shield 29 may further include a casing 29.2 made of, for example, polypropylene or acrylonitrile butadiene styrene or any other similar material. The casing 29.2 may be disposed partially or entirely on an outer surface of the sheath 29.1. The casing 29.2 may provide further support to the sheath 29.1 to, for example, prevent the needle 26 from bending or puncturing the sheath 29.1. When the needle shield 29 is removed, the needle 26 is exposed.

(16) FIG. 3 shows an exemplary embodiment of a safety device 30 according to the present invention. In the exemplary embodiment, the safety device 30 comprises a first sheath 31 arranged telescopically with a second sheath 32, and the sheaths 31, 32 which are biased relative to each other by a spring 33. Prior to use, one of the sheaths is in a retracted position relative to the other sheath, and after use, the one of the sheaths is in an extended position relative to the other sheath to cover the needle 26. In the extended position, the one of the sheaths is locked in the extended position to prevent retraction and uncovering of the needle 26.

(17) In the exemplary embodiment shown in FIG. 3, the first sheath 31 is an outer sheath, and the second sheath 32 is an inner sheath, and the second sheath 32 is movable from the retracted position to the extended position relative to the first sheath 31. The first sheath 31 comprises an open distal end allowing the second sheath 32 to move from the retracted position to the distal position. A proximal end of the first sheath 31 includes an engagement arrangement 34 adapted to engage the flange 28 of the medicament container 20. In an exemplary embodiment, the engagement arrangement 34 includes a support surface 34.1 adapted to abut a distal surface of the flange 28 to prevent distal movement of the medicament container 20 relative to the first sheath 31, and one or more resilient hooks 34.2 adapted to engage the flange 28 to prevent proximal movement of the medicament container 20 relative to the first sheath 31. When the medicament container 20 is inserted into the first sheath 31, the flange 28 causes the resilient hooks 34.2 to deflect until the flange 28 is distal of the hooks 34.2, at which point the hooks 34.2 return to a non-deflected position and can abut a proximal surface of the flange 28.

(18) In an exemplary embodiment, the proximal end of the first sheath 31 includes an inner ledge 35 and an outer ledge 36. The inner ledge 35 may be formed partially or entirely around a proximal opening of the first sheath 31. The outer ledge 36 may be formed partially or entirely around an outer surface of the first sheath 31. As shown in the exemplary embodiment in FIG. 3, the first sheath 31 may have a distal portion having a first outer diameter and a proximal portion having a second outer diameter which is larger than the first outer diameter. The outer ledge 36 may be formed partially or entirely around the larger second outer diameter to provide a support surface for a user's fingers.

(19) In an exemplary embodiment, the second sheath 32 comprises an open distal end allowing the needle 26 to pass through when the second sheath 32 is in the retracted position. A proximal end of the second sheath 32 includes one or more resilient arms 37 adapted to releaseably engage the inner ledge 35 to maintain the second sheath 32 in the retracted position against the force of the spring 33 which biases the second sheath 32 towards the extended position. When the second sheath 32 is in the retracted position, the resilient arms 37 are radially biased to engage the inner ledge 35.

(20) In an exemplary embodiment, the first sheath 31 is made from polycarbonate, the second sheath is made from copolyesther, and the spring 33 is made from stainless steel.

(21) FIGS. 4A and 4B show an exemplary embodiment of a plunger 40 according to the present invention. In the exemplary embodiment, the plunger 40 includes a distal end 41 adapted to engage the stopper 24, a proximal end 42 adapted to be pressed by a user, and a stem 43 connecting the distal and proximal ends 41, 42. FIG. 4B shows a partial cross-section of an exemplary embodiment of the proximal end 42 of the plunger 40. In the exemplary embodiment, the proximal end 42 includes a bearing surface 42.1 adapted to receive a user's finger. The bearing surface 42.1 may be flat (perpendicular relative to a longitudinal axis of the medicament container 20) or have a partially or entirely concave or convex surface. In another exemplary embodiment, the bearing surface 42.1 may have one or more surface elements (e.g., ridges, bumps, etc.) adapted to frictionally engage the user's finger to prevent it from slipping off the bearing surface 42.1 during use. The proximal end 42 further includes a radial surface 42.2 having a distal end that is adapted to engage one or more resilient projections on the first sheath 31 that deflect upon engagement with the radial surface 42.2 to engage the one or more resilient arms 37 on the second sheath 32 when the plunger 40 has been pressed a sufficient distance relative to the medicament container 20. In an exemplary embodiment, the distal end of the radial surface 42.2 may comprise one or more ramps 42.3 adapted to engage the resilient projections such that the resilient rejections resilient arms 37 deflect and disengage the inner ledge 35.

(22) In an exemplary use, when the plunger 40 is pressed a sufficient distance, the ramps 42.3 engage the resilient projections which engage the resilient arms 37 such that the resilient arms 37 deflect and disengage the inner ledge 35. The force of the spring 33 pushes the second sheath 32 distally relative to the first sheath 31 from the retracted position to the extended position. The second sheath 32 is locked in the extended position, because the resilient arms 37 abut a stop surface 31.1 (shown in FIG. 3) on the first sheath 31 preventing the second sheath 32 from moving proximally relative to the first sheath 31 from the extended position.

(23) In an exemplary embodiment, the plunger 40 is made from polypropylene or acrylonitrile butadiene styrene.

(98) or a pharmaceutically acceptable salt or solvate of any one of the afore-mentioned Exendin-4 derivative.

(99) Hormones are for example hypophysis hormones or hypothalamus hormones or regulatory active peptides and their antagonists as listed in Rote Liste, ed. 2008, Chapter 50, such as Gonadotropine (Follitropin, Lutropin, Choriongonadotropin, Menotropin), Somatropine (Somatropin), Desmopressin, Terlipressin, Gonadorelin, Triptorelin, Leuprorelin, Buserelin, Nafarelin, Goserelin.

(100) A polysaccharide is for example a glucosaminoglycane, a hyaluronic acid, a heparin, a low molecular weight heparin or an ultra low molecular weight heparin or a derivative thereof, or a sulphated, e.g. a poly-sulphated form of the above-mentioned polysaccharides, and/or a pharmaceutically acceptable salt thereof. An example of a pharmaceutically acceptable salt of a poly-sulphated low molecular weight heparin is enoxaparin sodium.

(101) Antibodies are globular plasma proteins (˜150 kDa) that are also known as immunoglobulins which share a basic structure. As they have sugar chains added to amino acid residues, they are glycoproteins. The basic functional unit of each antibody is an immunoglobulin (Ig) monomer (containing only one Ig unit); secreted antibodies can also be dimeric with two Ig units as with IgA, tetrameric with four Ig units like teleost fish IgM, or pentameric with five Ig units, like mammalian IgM.

(102) The Ig monomer is a “Y”-shaped molecule that consists of four polypeptide chains; two identical heavy chains and two identical light chains connected by disulfide bonds between cysteine residues. Each heavy chain is about 440 amino acids long; each light chain is about 220 amino acids long. Heavy and light chains each contain intrachain disulfide bonds which stabilize their folding. Each chain is composed of structural domains called Ig domains. These domains contain about 70-110 amino acids and are classified into different categories (for example, variable or V, and constant or C) according to their size and function. They have a characteristic immunoglobulin fold in which two β sheets create a “sandwich” shape, held together by interactions between conserved cysteines and other charged amino acids.

(103) There are five types of mammalian Ig heavy chain denoted by α, δ, ε, γ, and μ. The type of heavy chain present defines the isotype of antibody; these chains are found in IgA, IgD, IgE, IgG, and IgM antibodies, respectively.

(104) Distinct heavy chains differ in size and composition; α and γ contain approximately 450 amino acids and δ approximately 500 amino acids, while μ and ε have approximately 550 amino acids. Each heavy chain has two regions, the constant region (C.sub.H) and the variable region (V.sub.H). In one species, the constant region is essentially identical in all antibodies of the same isotype, but differs in antibodies of different isotypes. Heavy chains γ, α and δ have a constant region composed of three tandem Ig domains, and a hinge region for added flexibility; heavy chains μ and ε have a constant region composed of four immunoglobulin domains. The variable region of the heavy chain differs in antibodies produced by different B cells, but is the same for all antibodies produced by a single B cell or B cell clone. The variable region of each heavy chain is approximately 110 amino acids long and is composed of a single Ig domain.

(105) In mammals, there are two types of immunoglobulin light chain denoted by λ and κ. A light chain has two successive domains: one constant domain (CL) and one variable domain (VL). The approximate length of a light chain is 211 to 217 amino acids. Each antibody contains two light chains that are always identical; only one type of light chain, κ or λ, is present per antibody in mammals.

(106) Although the general structure of all antibodies is very similar, the unique property of a given antibody is determined by the variable (V) regions, as detailed above. More specifically, variable loops, three each the light (VL) and three on the heavy (VH) chain, are responsible for binding to the antigen, i.e. for its antigen specificity. These loops are referred to as the Complementarity Determining Regions (CDRs). Because CDRs from both VH and VL domains contribute to the antigen-binding site, it is the combination of the heavy and the light chains, and not either alone, that determines the final antigen specificity.

(107) An “antibody fragment” contains at least one antigen binding fragment as defined above, and exhibits essentially the same function and specificity as the complete antibody of which the fragment is derived from. Limited proteolytic digestion with papain cleaves the Ig prototype into three fragments. Two identical amino terminal fragments, each containing one entire L chain and about half an H chain, are the antigen binding fragments (Fab). The third fragment, similar in size but containing the carboxyl terminal half of both heavy chains with their interchain disulfide bond, is the crystalizable fragment (Fc). The Fc contains carbohydrates, complement-binding, and FcR-binding sites. Limited pepsin digestion yields a single F(ab′)2 fragment containing both Fab pieces and the hinge region, including the H—H interchain disulfide bond. F(ab′)2 is divalent for antigen binding. The disulfide bond of F(ab′)2 may be cleaved in order to obtain Fab′. Moreover, the variable regions of the heavy and light chains can be fused together to form a single chain variable fragment (scFv).

(108) Pharmaceutically acceptable salts are for example acid addition salts and basic salts. Acid addition salts are e.g. HCl or HBr salts. Basic salts are e.g. salts having a cation selected from alkali or alkaline, e.g. Na+, or K+, or Ca2+, or an ammonium ion N+(R1)(R2)(R3)(R4), wherein R1 to R4 independently of each other mean: hydrogen, an optionally substituted C1-C6-alkyl group, an optionally substituted C2-C6-alkenyl group, an optionally substituted C6-C10-aryl group, or an optionally substituted C6-C10-heteroaryl group. Further examples of pharmaceutically acceptable salts are described in “Remington's Pharmaceutical Sciences” 17. ed. Alfonso R. Gennaro (Ed.), Mark Publishing Company, Easton, Pa., U.S.A., 1985 and in Encyclopedia of Pharmaceutical Technology.

(109) Pharmaceutically acceptable solvates are for example hydrates.
