Clinical Peptides & Pools

Clinical Peptides & Peptide Pools 

Clinical use peptides are increasingly needed as an antigen source for clinical immune monitoring, diagnostics, cell therapy and vaccine development. The diversity of applications and regulatory requirements calls for a flexible, high quality soruce for your clinical peptides. JPT is that source with its outstanding know-how on peptide antigen formats, peptide specifications and formulation, peptide manufacturability and properties as well as critical analytical release testing and batch documentation guaranteeing smooth transition from research to clinical application.

JPT's Clinical Peptides

Building on our ISO 9001:2015 certified quality management system JPT established an enhanced peptide production environment that adds critical quality measures to the standard RuO (research use only) production, which are mandatory for clinical peptides and peptide pools. Resulting quality levels termed ISO PLUS Peptides and Clinical Grade Peptides focus on the more stringent requirements of immunotherapy, cell therapy, clinical immune monitoring, clinical proteomics as well as vaccine & drug development and have been approved for a variety of clinical applications.

Disclaimer: Peptides of Clinical Grade and ISO PLUS specification are designed, manufactured and tested under an ISO 9001 certified quality system. Peptides and peptide pools are intented for in vitro and research purposes only. Any use beyond this intented use requires the explicit approval of the customer’s legislative and regulatory agencies. The customer is obliged to obtain advice from local regulatory authority and shall be solely responsible to ensure that the products are suitable for customer’s particular use and that intented use will not infringe statutory law. JPT invites its customers to visit, inspect and audit its facilities to verify if peptides or peptide pools produced under Clinical Grade or ISO PLUS conditions are suited for a specific application.

Testimonials for Clinical Peptides & Pools

"My group is developing therapeutic strategies for using in vitro expanded virus-specific T cells (VSTs) for the treatment of viral infections in immunocompromised patients. We recently demonstrated the feasibility and clinical benefit associated with the infusion of rapidly generated single-culture VSTs, manufactured using JPT's Clinical Grade PepMix™ peptide pools covering 12 immunogenic antigens from five viruses (EBV, AdV, CMV, BK, and HHV6). When administered to 11 allogeneic stem cell transplant recipients, 8 of whom had up to four active infections, these VSTs produced an overall 94% response rate."
Ann Leen, PhD, Baylor College of Medicine, Houston, TX, USA

"We utilize customized 15-mer PepMix™ peptide pools encoding for weak tumor associated antigens for immunomonitoring of cancer patients treated with recombinant therapeutic vaccines. Our experience with JPT has been outstanding in regard to product quality and communication with scientific and administrative customer service. JPT is the only company we trust to synthesize the 15-mer peptides and corresponding pools for our clinical trial evaluations."
Benedetto Farsaci, MD, National Cancer Institute, NIH, Bethesda, MD, USA

"Our work focuses on TGF-beta in physiology and cancer as well as the differentiation and expansion of human T cells in vitro for adoptive immunotherapy. For our early phase clinical trials we are in need of T cell EBV specific stimulants having an exceptional quality. JPT's customized PepMix™ Peptide Pools not only proved to deliver excellent performance in our in vitro culture systems but accompanying QC/QA documentation was essential to prepare our application to our regulatory agency.”
Dr. Jean-Sébastien Delisle, Université de Montréal, Centre de recherche de l'Hôpital Maisonneuve-Rosemont, Canada
