Peptide Uses for Immunotherapy & Cell Therapy

About Immunotherapy & Cell Therapy

 Cellular therapy (also called cell therapy or cytotherapy) & immunotherapy aim to treat or prevent disease by injecting living cells or (peptide) vaccines into the patient (e.g. cancer immunotherapy). There are multiple strategies for cell therapy that differ by the cell type or the method used. Examples include types of cell therapy like allogeneic cell therapy, embryonic stem cell therapy, or immunotherapy. Immunological cytotherapy approaches like adoptive T cell therapy (including CAR), and dendritic cell therapy as a vaccination strategy use peptides to produce different types of antigen-specific immune cells e.g. for cancer immunotherapy

Benefits of Using Peptides as Antigens for Immunotherapy & Cell Therapy

  • Neo-epitopes enable personalized therapies
  • Peptides ensure robust epitope resolved immune monitoring
  • Only peptides allow the study of B- and T-cell epitope spreading
  • Peptides can be synthesized in high purities
  • Peptides allow proteome-wide target identification
  • No antigen expression needed, ADCF policy applicable
  • Sequence diversity and post-translational modifications can be addressed

JPT's Peptide Resources for Immunotherapy & Cell Therapy:

JPT GxP peptides are not intended for human in vivo application.  JPT does not warrant that any peptides and peptide pools produced under GxP conditions are applicable in clinical applications (clinical grade peptides). JPT invites its customers to visit, inspect and audit our facilities to make an educated decision on whether or not peptides or peptide pools produced under GxP conditions are suited for a specific application.

Selected Testimonials for Immunotherapy & Cell Therapy

"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 GxP 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, 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
