Priming the Body to Receive the Therapeutic Agent to Redefine
www.nature.com/scientificreports OPEN Priming the body to receive the therapeutic agent to redefne treatment beneft/risk profle Received: 24 October 2017 Matthieu Germain, Marie-Edith Meyre, Laurence Poul, Marion Paolini, Céline Berjaud, Francis Accepted: 6 March 2018 Mpambani, Maxime Bergere, Laurent Levy & Agnès Pottier Published: xx xx xxxx Many therapeutic agents ofer a low useful dose (dose responsible for efcacy)/useless dose (dose eliminated or responsible for toxicity) ratio, mainly due to the fact that therapeutic agents must ensure in one single object all the functions required to deliver the treatment, which leads to compromises in their physico-chemical design. Here we introduce the concept of priming the body to receive the treatment by uncorrelating these functions into two distinct objects sequentially administered: a nanoprimer occupying transiently the main pathway responsible for therapeutic agent limited beneft/risk ratio followed by the therapeutic agent. The concept was evaluated for diferent nature of therapeutic agents: For nanomedicines we designed a liposomal nanoprimer presenting preferential hepatic accumulation without sign of acute toxicity. This nanoprimer was able to increase the blood bioavailability of nanomedicine correlated with a lower hepatic accumulation. Finally this nanoprimer markedly enhanced anti-tumor efcacy of irinotecan loaded liposomes in the HT-29 tumor model when compared to the nanomedicine alone. Then, for small molecules we demonstrated the ability of a cytochrome inhibitor loaded nanoprimer -

Conventional TB drugs are less effective because of poor intracellular delivery to this bacterial sanctuary. This study highlights the potential of using semicrystalline delta inulin particles that are readily internalised by monocytes for a monocyte-based drug delivery system. Pyrazinoic acid was successfully attached covalently to the delta inulin particles via a labile linker. -
Advances in Nanomaterials in Biomedicine
nanomaterials Editorial Advances in Nanomaterials in Biomedicine Elena Ryabchikova Institute of Chemical Biology and Fundamental Medicine, Siberian Branch of Russian Academy of Science, 8 Lavrentiev Ave., 630090 Novosibirsk, Russia; [email protected] Keywords: nanotechnology; nanomedicine; biocompatible nanomaterials; diagnostics; nanocarriers; targeted drug delivery; tissue engineering Biomedicine is actively developing a methodological network that brings together biological research and its medical applications. Biomedicine, in fact, is at the front flank of the creation of the latest technologies for various fields in medicine, and, obviously, nanotechnologies occupy an important place at this flank. Based on the well-known breadth of the concept of “Biomedicine”, the boundaries of the Special Issue “Advances in Nanomaterials in Biomedicine” were not limited, and authors could present their work from various fields of nanotechnology, as well as new methods and nanomaterials intended for medical applications. This approach made it possible to make public not only specific developments, but also served as a kind of mirror reflecting the most active interest of researchers in a particular field of application of nanotechnology in biomedicine. The Special Issue brought together more than 110 authors from different countries, who submitted 11 original research articles and 7 reviews, and conveyed their vision of the problems of nanomaterials in biomedicine to the readers. A detailed and well-illustrated review on the main problems of nanomedicine in onco-immunotherapy was presented by Acebes-Fernández and co-authors [1]. It should be noted that the review is not limited to onco-immunotherapy, and gives a complete understanding of nanomedicine in general, which is useful for those new to this field. -

Aura Gimm is Assistant Professor of the Practice and Associated Director of Undergraduate Studies in the Department of Biomedical Engineering at Duke University. She teaches courses in biomaterials, thermodynamics/kinetics, engineering design, and a new course in bionanotechnology. Dr. Gimm received her S.B. in Chemical Engineering and Biology from MIT, and her Ph.D. in Bioengineering from UC-Berkeley. Page 14.802.1 Page © American Society for Engineering Education, 2009 Introducing Bionanotechnology in Undergraduate Biomedical Engineering Abstract As a part of the NSF-funded Nanotechnology Undergraduate Education Program, we have developed and implemented a new upper division elective course in Biomedical Engineering titled “Introduction to Bionanotechnology Engineering”. The pilot course included five hands- on “Nanolab” modules that guided students through specific aspects of nanomaterials and engineering design in addition to lecture topics such as scaling effects, quantum effects, electrical/optical properties at nanoscale, self-assembly, nanostructures, nanofabrication, biomotors, biological designing, biosensors, etc. Students also interacted with researchers currently working in the areas of nanomedicine, self-assembly, tribiology, and nanobiomaterials to learn first-hand the engineering and design challenges. The course culminated with research or design proposals and oral presentations that addressed specific engineering/design issues facing nanobiotechnology and/or nanomedicine. The assessment also included an exam (only first offering), laboratory write-ups, reading of research journal articles and analysis, and an essay on ethical/societal implications of nanotechnology, and summative questionnaire. The course exposed students to cross-disciplinary intersections that occur between biomedical engineering, materials science, chemistry, physics, and biology when working at the nanoscale. -

Nanobiotix and Thomas Jefferson University Start Research
Nanobiotix and Thomas Jefferson University Start Research Collaboration Nanomedicine and Medical Education leaders are joining their forces in the United States to accelerate the development of NanoXray Paris, France and Philadelphia, USA – May 2 2012 - Nanobiotix, a company developing novel cancer nanotherapeutics and Thomas Jefferson University, one of Philadelphia's premier medical and health sciences universities, today announced that they have entered into a research collaboration to accelerate the development of Nanobiotix’ lead compound NBTXR3 in the US. Under the terms of the collaboration agreement, Nanobiotix will fund a 2-year preclinical research program, which will be directed by Bo Lu, MD, Professor in the Department of Radiation Oncology at Jefferson and Director of the department’s Division of Molecular Radiation Biology. The goal of the program is to study the therapeutic efficacy of NBTXR3, the lead product of Nanobiotix´ NanoXray pipeline. NBTXR3, a nanoparticle consisting of hafnium oxide crystals, aims to enhance the local destruction of the tumor mass during radiotherapy. It accumulates in the cancer cells and, upon radiation, emits huge amounts of electrons leading to the formation of free radicals. These, in turn, damage the cancer cells and cause their targeted destruction. As a result, the destructive power of standard radiation therapy is locally and selectively enhanced within the tumor cells. “For the treatment of cancer, it is important to develop ways that cause tumor cells to be more sensitive to radiation therapy,” said Dr. Bo Lu. “ We therefore are very interested in approaches that have the potential to amplify the power of the radiation dose inside the tumor without damaging the surrounding healthy cells. -

Personalized Nanomedicine
Published OnlineFirst July 24, 2012; DOI: 10.1158/1078-0432.CCR-12-1414 Clinical Cancer Perspective Research Personalized Nanomedicine Twan Lammers1,2,3, Larissa Y. Rizzo1, Gert Storm2,3, and Fabian Kiessling1 Abstract Personalized medicine aims to individualize chemotherapeutic interventions on the basis of ex vivo and in vivo information on patient- and disease-specific characteristics. By noninvasively visualizing how well image-guided nanomedicines—that is, submicrometer-sized drug delivery systems containing both drugs and imaging agents within a single formulation, and designed to more specifically deliver drug molecules to pathologic sites—accumulate at the target site, patients likely to respond to nanomedicine-based therapeutic interventions may be preselected. In addition, by longitudinally monitoring how well patients respond to nanomedicine-based therapeutic interventions, drug doses and treatment protocols can be individualized and optimized during follow-up. Furthermore, noninvasive imaging information on the accumulation of nanomedicine formulations in potentially endangered healthy tissues may be used to exclude patients from further treatment. Consequently, combining noninvasive imaging with tumor-targeted drug delivery seems to hold significant potential for personalizing nanomedicine-based chemotherapeutic interventions, to achieve delivery of the right drug to the right location in the right patient at the right time.
