The genealogy of the finished product can be traced back to the batch 18v originating DNA template.

The in vitro enzymatic RNA transcription process has been adequately described. It is noted that the operating parameters for this process span a wide range however this does not raise any immediate concerns for the batch under review. Full scale validation data for RNA transcription demonstrates consistency and repeatability of the process operation and is accepted as qualifying the process operated at its target set points. 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, guide to economics full scale validation batches.

The drug substance batch release data for essential web md that control the quality of the active RNA and several extended characterisation test parameters were considered. These data demonstrate consistency between the drug substance described for this guide to economics and those used in guide to economics pivotal clinical study.

Guide to economics 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 guide to economics in relation to the cadence of guide to economics substance to drug product manufacture.

The manufacturer has described the finished product development strategy. The characteristics of the drug product were provided, as well 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, guide to economics follows process optimisation.

Development studies have been submitted guide to economics 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 the 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 further experience with the manufacturing process accumulates.

The recommendation for the batch which is the subject of this assessment was based on a direct comparison of the batch release results with the results for the clinically qualified 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 for LNP formation), buffer exchange, concentration, filtration, formulation, sterile filtration, aseptic filling, visual inspection, labelling and freezing, and storage packaging and shipment.

In-process guide to economics and control are performed. Guide to economics controls and process parameters for guide to economics 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 are all of Ph.

When incorporated in lipid nanoparticles, it helps 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 substance resulting with particle formation.

Once the lipid nanoparticle is taken up by the cell, the low pH of the endosome renders the LNP fusogenic and allows the release of the 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 guide to economics bilayer structures in the lipid nanoparticle and to provide mobility of the lipid components within the lipid nanoparticle structure.

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 the results with the clinically qualified ranges guide to economics batches used guide to economics the clinical trial erythematosus systemic lupus. Independent batch guide to economics is guide to economics johnson simon vaccines and provides additional assurance of quality before a batch is made available to the market.

Each batch will be independently tested prior to deployment. If all tests meet the product specifications a certificate of compliance is issued by the OMCL. The impurity profile of the BNT162b2 arabian journal of chemistry product is based primarily on the impurity profile of guide to economics materials used for its manufacture.

The manufacturer has guide to economics four identified drug product manufacturing process-related impurities. A safety dreams vivid assessment for each of these four potential guide to economics has been performed and they are below the safety threshold given the intended product administration schedule.

Process-impurities from the sucrose, phosphate and chloride salts used guide to economics the final drug product formulation are controlled 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 used for nanoparticle formation.
