Supply of Viral Vector Plasmids

Tender description

Viral Vector Plasmids. Please note this is not the start of a procurement process. A separate contract notice will be published to cover this requirement. Lot 1: NHS Blood & Transplant (NHSBT) are seeking to engage with suppliers of plasmids for Adeno-associated Viral (AAV) vectors, Lentiviral (LV) vectors and other clinically relevant viral vector types via an early market engagement exercise.<br/><br/>NHSBT Clinical Biotechnology Centre (CBC), Filton is part of the Cellular and Molecular Therapies (CMT) function and one of the Innovation Hubs for Gene Therapies in the UK. The CBC, is part of the strategic business CMT function of NHSBT, providing specialist advanced therapy manufacturing services for clinical trials such as gene therapies. CBC services are part of a national network of four laboratories across England which have a Medicines and Healthcare products Regulatory Agency (MHRA) regulated license for the manufacturing of investigational medicinal products. NHSBT offers viral vector manufacturing services to the Advanced Therapy Medicinal Product (ATMP) sector. NHSBT operates on a not-for-profit basis to support the gene therapy clinical translation from academic and other organisations, therefore cost effectiveness of plasmids is a key factor.<br/><br/>NHSBT seeks to engage with suppliers who provide plasmids with a proven transfection system suitability to produce high titre of viral vectors with greater ratios of full capsids by maintaining required quality standards for the use of these products in clinical use. <br/><br/>NHSBT’s requirement is likely to include the following:<br/><br/>• Plasmids must meet the quality standards for viral vector production for clinical use. <br/>• Plasmids should be available at different quality standards including Research and Development (R&D) grade, High-Quality and Good Manufacturing Practices (GMP) grade.<br/>• It is recognised that newer and innovative viral vector plasmids/plasmid systems may become available and that NHSBT may wish to take advantage of these. The supplier must notify NHSBT of any such new developments which are relevant and, where mutually agreed, work with NHSBT to introduce these and make them available to NHSBT.<br/>• AAV Plasmids should be available for all common AAV serotypes. along with any newer and innovative serotypes.<br/>• Plasmids need to be available in different pack sizes from 1mg to 2g.<br/>• All necessary plasmids should be available.<br/>• Plasmids should demonstrate high titre/yield and packaging efficiency.<br/>• AAV Plasmids should demonstrate high ratio of full capsids.<br/>• Demonstration of suitability of the plasmids with different transfection systems is critical.<br/>• Availability of different qualified plasmid identification tests and residual plasmid detections test to satisfy required regulatory authority is advisable. <br/><br/>As part of the early market engagement exercise, NHSBT would like to discuss our requirement with suppliers along with: time frame for supply; whether plasmid suppliers also provide consumables etc; and what innovative plasmids may be available.<br/><br/>It should be noted that other health authorities may be permitted to use any agreements awarded. <br/><br/>It is NHSBT's intention to hold the early market engagement exercise supplier meetings the week of 28th October 2024 (note: dates are subject to change).
