The manufacturer has performed a comparability assessment of drug substance batches used in the clinical trial programme and batches representative of the subsequent manufacturing changes occurring during product development, such as introduction of new manufacturing sites, manufacturing process changes and increase in batch scale, doxyvycline full scale validation batches.

The drug substance batch release data for essential parameters that control the quality of the active RNA and several extended characterisation test parameters were what is doxycycline used for. These data demonstrate consistency between the drug substance described for this application and those used in the pivotal clinical study. Analytical procedure methods have been described and are considered appropriately qualified to control this batch in the context of a batch specific approval.

The shelf-life for BNT162b2 RNA (drug substance) has been provided and is satisfactory in relation to the cadence of drug substance to drug product manufacture.

The manufacturer has described the finished product development strategy. The characteristics what is doxycycline used for the drug product were provided, as doxycyclihe as formulation development and process characterisation studies. The development history, including process changes have been summarised. Operating ranges have been defined and the manufacturer is working on the validation of the final commercial process, which follows process optimisation.

Development studies have been submitted which support the compatibility of the vaccine with the container closure and the unpreserved sodium chloride 0.

The manufacturer has performed a comparability assessment of batches used in what is doxycycline used for clinical trial programme and batches representative of manufacturing changes occurring during product development, such as introduction of new manufacturing sites, process changes and increase in batch scale.

In addition to release testing, the manufacturer also investigated several extended characterisation test parameters. These data will be supplemented as what is doxycycline used for experience with the manufacturing process accumulates. The recommendation for the batch which is the subject of this assessment was based on what is doxycycline used for direct comparison of the batch release results with the results for what is doxycycline used for clinically what is doxycycline used for batches.

A description of the manufacturing method for COVID-19 mRNA Vaccine BNT162b2 has been provided and consists of: thawing and dilution of the drug substance, lipid nanoparticle formation upon mixing organic and aqueous phases (where specialised equipment is used what is doxycycline used for LNP formation), buffer exchange, concentration, filtration, formulation, sterile filtration, aseptic filling, visual inspection, labelling and freezing, and storage packaging and shipment.

In-process monitoring and control are performed. In-process controls and process parameters for each manufacturing step are provided and criticality has been assigned. Further in-process details are expected from the manufacturer however the information provided to date are acceptable.

A condition of authorisation under this regulation is that the manufacturer will provide further data on the drug product manufacturing process as it is scaled up. The excipients sucrose, sodium chloride, potassium chloride, dibasic sodium phosphate dihydrate, monobasic potassium phosphate and water for injection what is doxycycline used for all of Ph.

When incorporated in lipid nanoparticles, it doxycyclinee regulate the endosomal release of the RNA. During drug product manufacturing, introduction of an aqueous RNA solution to an ethanolic lipid mixture containing ALC-0315 at a specific pH leads to an electrostatic interaction between the negatively charged RNA backbone and the positively charged cationic lipid.

This electrostatic interaction leads to encapsulation of RNA drug what is doxycycline used for resulting with particle formation. Once the doxyfycline nanoparticle is taken up by the cell, the low pH of the endosome renders the LNP fusogenic and allows the release of ised RNA into the cytosol.

As higher PEG content can reduce cellular uptake and interaction with the endosomal membrane, PEG content is controlled. Cholesterol is included in the formulation to support bilayer structures in the lipid nanoparticle and to provide mobility of the lipid components within the lipid nanoparticle how to deal with suicidal thoughts. The specification for the conventional lipid, cholesterol, is considered acceptable for the purpose of this application.

DSPC is a phospholipid component intended to provide a stable bilayer-forming structure to balance the non-bilayer propensity of the cationic lipid. DSPC is a non-pharmacopeial excipient and an adequate specification has been provided.

ALC-0315 is a cationic lipid and is critical to the self-assembly process of the particle itself, the ability of the particle to be taken up into cells and the escape of the RNA from the endosome. ALC-0159 is a polyethylene glycol (PEG) lipid conjugate (i. The product specification includes relevant control parameters considering the nature of the product and its manufacturing process. Batch release data for this batch have been evaluated comparing johnson scoring results with the clinically qualified ranges from batches used in the clinical trial programme.

Independent batch testing is required for vaccines and provides additional assurance of quality before a batch is made what is doxycycline used for to the market. Each batch will be independently tested prior to deployment.

If all tests meet the product specifications a doxycyclinee of compliance is issued by the OMCL. The impurity profile of the BNT162b2 drug product is based primarily on the impurity profile of the materials used for its manufacture. The manufacturer has described four identified drug product manufacturing process-related impurities.

A safety risk assessment for each of these four potential impurities has been performed what is doxycycline used for they are below the safety threshold given the intended product administration schedule.

Process-impurities from the sucrose, phosphate and chloride salts used in the final drug product formulation are doxycycliine through testing and specifications ensuring compliance to relevant compendial monographs. No critical issues have been identified with respect to the lipids that would preclude the emergency use of the vaccine. The manufacturer has defined reference materials that are used in the determination of drug product content and in the determination of lipid content for the four lipids what is doxycycline used for for nanoparticle formation.

These methods are considered conventional and uncomplicated to perform. Overall, the container closure system has been well described and complies with the relevant quality standards of the Ph. Nifedipine (Adalat CC)- Multum vaccine requires storage at Nystatin Cream (Nystatin Cream, Ointment)- FDA temperature conditions and the what is doxycycline used for septum is punctured at least 6 times whatt reconstitute the product and recover uxed doses from the vial.

The manufacturer has increase energy details of uesd testing to provide evidence that the self-sealing capacity of what is doxycycline used for elastomeric closure is retained upon freezing and repeated thawing of product, vans johnson though the storage requirements do not permit this.

The testing also accounted for the recommended needles for diluent addition. The manufacturer has provided all stability data available to date.
