Therapeutic peptide vaccines have the potential to elicit and direct an anti-cancer T cell response, but their clinical efficacy has been limited in part by poor delivery to the lymphatic system, inefficient cell uptake, and scalable synthesis in the case of personalized vaccines. The work presented in this thesis explores several approaches to address these challenges. First, we use our fast-flow automated synthesis technology to confront the synthesis bottleneck for patient-specific 'neoantigen' vaccines, which have shown early promise but are hindered by slow production. We synthesize a particularly challenging set of peptides from a previous clinical trial as a test case, demonstrating that our technology can produce the majority of sequences in sufficient quantities with comparable or higher purity than a commercial vendor in a fraction of the time. Turning towards vaccine design, we explore several approaches to address the lymphatic and intracellular delivery of peptide antigens. We demonstrate the generality and anti-tumor efficacy of vaccines containing cell-penetrating peptides (CPPs), sequences shown to enhance the cell uptake of various cargo. We characterize their mechanism and identify several unanticipated contributors, namely trafficking to the lymph nodes, serum stability, and extended presentation in vivo. We then expand on an existing approach to mediate lymphatic trafficking via binding serum albumin by exploring additional albumin binding moieties. Next, we develop a straightforward and general approach to directly quantify antigen presentation and implement this technique to explore two strategies to design more effective vaccines, including CPPs. Finally, we build on previous work using CPPs to deliver antisense oligonucleotides (ASOs), another application that we pursued in tandem with cancer vaccines. We combine amphipathic and cationic CPPs to create chimeric sequences that synergistically enhance activity of an ASO and access new routes of uptake not utilized by either parent CPP. Drawing from our experience using CPPs to deliver ASOs as well as our expertise in peptide synthesis and design, we provide insight into the rapid production of personalized vaccines and efficient delivery of vaccine antigens. This thesis represents a new area of research for our lab, one in which we will hopefully continue to apply our unique skillset and perspective.

Rapid progress in the definition of tumor antigens, and improved immunization methods, bring effective cancer vaccines within reach. In this wide-ranging survey, leading clinicians and scientists review therapeutic cancer vaccine strategies against a variety of diseases and molecular targets. Intended for an interdisciplinary readership, their contributions cover the rationale, development, and implementation of vaccines in human cancer treatment, with specific reference to cancer of the cervix, breast, colon, bladder, and prostate, and to melanoma and lymphoma. They review target identification, delivery vectors and clinical trial design. The book begins and ends with lucid overviews from the editors, that discuss the most recent developments.

With potentially high specificity and low toxicity, biologicals offer promising alternatives to small-molecule drugs. Peptide therapeutics have again become the focus of innovative drug development efforts backed up by a resurgence of venture funds and small biotechnology companies. What does it take to develop a peptide-based medicine? What are the key challenges and how are they overcome? What are emerging therapeutics for peptide modalities? This book answers these questions with a holistic story from molecules to medicine, combining the themes of design, synthesis and clinical applications of peptide-based therapeutics and biomarkers. Chapters are written and edited by leaders in the field from industry and academia and they cover the pharmacokinetics of peptide therapeutics, attributes necessary for commercially successful metabolic peptides, medicinal chemistry strategies for the design of peptidase-resistant peptide analogues, disease classes for which peptide therapeutic are most relevant, and regulatory issues and guidelines. The critical themes covered provide essential background information on what it takes to develop peptide-based medicine from a chemistry perspective and views on the future of peptide drugs. This book will be a valuable resource not only as a reference book for the researcher engaged in academic and pharmaceutical setting, from basic research to manufacturing and from organic chemistry to biotechnology, but also a valuable resource to graduate students to understand discovery and development process for peptide-based medicine.

This book features a special subsection of Nanomedicine, an application of nanotechnology to achieve breakthroughs in healthcare. It exploits the improved and often novel physical, chemical and biological properties of materials only existent at the nanometer scale. As a consequence of small scale, nanosystems in most cases are efficiently uptaken by cells and appear to act at the intracellular level. Nanotechnology has the potential to improve diagnosis, treatment and follow-up of diseases, and includes targeted drug delivery and regenerative medicine; it creates new tools and methods that impact significantly upon existing conservative practices. This volume is a collection of authoritative reviews. In the introductory section we define the field (intracellular delivery). Then, the fundamental routes of nanodelivery devices, cellular uptake, types of delivery devices, particularly in terms of localized cellular delivery, both for small drug molecules, macromolecular drugs and genes; at the academic and applied levels, are covered. The following section is dedicated to enhancing delivery via special targeting motifs followed by the introduction of different types of intracellular nanodelivery devices (e.g. a brief description of their chemistry) and ways of producing these different devices. Finally, we put special emphasis on particular disease states and on other biomedical applications, whilst diagnostic and sensing issues are also included. Intracellular delivery / therapy is a highly topical which will stir great interest. Intracellular delivery enables much more efficient drug delivery since the impact (on different organelles and sites) is intracellular as the drug is not supplied externally within the blood stream. There is great potential for targeted delivery with improved localized delivery and efficacy.
