Definitions
- the invention relates to a medicament cartridge.
- Administering an injection is a process which presents a number of risks and challenges for users and healthcare professionals, both mental and physical.
- Injection devices typically fall into two categories - manual devices and autoinjectors.
- a user In a conventional manual device, a user must provide force to drive a medicament through a needle. This is typically done by some form of button / plunger that has to be
- the injection will stop and may not deliver an intended dose to a patient.
- the force required to push the button/plunger may be too high for the user (e.g., if the user is elderly).
- aligning the injection device, administering the injection and keeping the injection device still during the injection may require dexterity which some patients (e.g., elderly patients, children, arthritic patients, etc.) may not have.
- Autoinjector devices aim to make self-injection easier for patients.
- a conventional autoinjector may provide the force for administering the injection by a spring, and a trigger button or other mechanism may be used to activate the injection.
- Autoinjectors may be single-use or reusable devices. Autoinjectors may be single-dose, delivering the entire contents of a cartridge or pre-filled syringe, or may be fixed-dose, delivering predetermined amounts from the cartridge or pre-filled syringe.
- a reusable autoinjector utilizes disposable safety needles and cartridges or pre-filled syringes. In the latter case, there is a risk of needlestick injury when inserting/removing a pre-filled syringe.
- the medicament cartridge further comprises a syringe including a stopper and a needle.
- the syringe includes a needle sheath removably covering the needle. In the extended position, the shield covers the needle.
- the medicament cartridge further comprises a lock adapted to lock the shield in the extended position.
- the lock includes one or more resilient arms adapted to deflect radially when the shield translates from the retracted position to the extended position. When the shield is in the extended position, the one or more arms abut the shield to prevent the shield from returning to the retracted position.
- the medicament cartridge further comprises a spring biasing the shield relative to the housing.
- the data storage device includes at least one of read-only memory, random access memory, magnetic memory, optical memory, mechanical memory, a bar code, an RFID tag, a QR code and thermal paper.
- the medicament cartridge further comprises an actuator in communication with the data storage device and adapted to release the shield from the retracted position.
- the medicament cartridge further comprises a sensor adapted to generate a signal indicative of at least one of removal of the needle sheath and movement of the shield from the retracted position to the extended position.
- the medicament data includes at least one of a medicament, a dose, a number of doses provided by the cartridge, a manufacturing date, a batch number, an expiration date, a use indicator, supply chain data, patient data, geographical data, storage condition data, and temperature data.
- the medicament cartridge further comprises a

- 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.
- 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 70-1 10 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 ⁇ sheets create a "sandwich" shape, held together by interactions between conserved cysteines and other charged amino acids.
- Ig heavy chain There are five types of mammalian Ig heavy chain denoted by ⁇ , ⁇ , ⁇ , ⁇ , and ⁇ .
- the type of heavy chain present defines the isotype of antibody; these chains are found in IgA, IgD, IgE, IgG, and IgM antibodies, respectively. Distinct heavy chains differ in size and composition; a and ⁇ contain approximately 450 amino acids and ⁇ approximately 500 amino acids, while ⁇ and ⁇ have approximately 550 amino acids.
- Each heavy chain has two regions, the constant region (CH) and the variable region (V 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 ⁇ , a and ⁇ have a constant region composed of three tandem Ig domains, and a hinge region for added flexibility; heavy chains ⁇ and ⁇ have a constant region
- 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 1 10 amino acids long and is composed of a single Ig domain.
- a light chain has two successive domains: one constant domain (CL) and one variable domain (VL).
- CL constant domain
- VL variable domain
- the approximate length of a light chain is 21 1 to 217 amino acids.
- Each antibody contains two light chains that are always identical; only one type of light chain, K or ⁇ , is present per antibody in mammals.
- variable (V) regions are responsible for binding to the antigen, i.e. for its antigen specificity.
- VL variable light
- VH variable heavy chain
- CDRs Complementarity Determining Regions
- 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 Fc contains carbohydrates, complement-binding, and FcR-binding sites.
- F(ab')2 is divalent for antigen binding.
- the disulfide bond of F(ab')2 may be cleaved in order to obtain Fab'.
- the variable regions of the heavy and light chains can be fused together to form a single chain variable fragment (scFv).
- Pharmaceutically acceptable salts are for example acid addition salts and basic salts.
- Acid addition salts are e.g. HCI 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
