The biopharmaceutical industry has been one of the most dynamic and promising sectors. The entry of Biotechnology start-ups in the 1980s led to the reconfiguration of the drug development value chain and the emergence of new competences. As the sector evolved, specialised firms appeared. As the industry matures, the production process becomes more specialised to support optimisation of technological steps. Our case studies reveal that the coordination of networks can be specialised, with the emergence of Dedicated Coordinating Firms. On the basis of four case studies of European biotechnology companies within a business model approach, this article helps understanding how coordinating a network can be successful and how small hub firms can do it.

Fibroblast growth factor (FGF) receptor 1 (FGFR1) is a potential therapeutic target for treatment of metastatic renal cell carcinoma (RCC). We investigated the preclinical activity of OM-RCA-01, a novel therapeutic humanized anti-FGFR1 antibody in RCC. OM-RCA-01 has been shown to inhibit in vitro kinase activity of FGFR1 and has high affinity (Kd of 1.59 nM). In human renal carcinoma Caki-1 FGFR1-expressing cells, OM-RCA-01 potently inhibited FGF-mediated signaling and proliferation. In vivo, the tumors in untreated mice or mice treated with non-specific IgG continued their aggressive growth to reach the size of 2,000 cm3, at which point the mice were killed. In contrast, treatment with OM-RCA-01 not only significant arrested further growth of the tumors (P < 0.01) but also demonstrated differences in tumor volume compared with vehicle already on Day 13. A similar anti-tumor activity of OM-RCA-01 was observed when the antibody was given in low (1 mg/kg) or high (10 mg/kg) doses (P = 0.917). In Matrigel assay, OM-RCA-01 significantly inhibited FGF-induced endothelial cell migration, capillary-like tubular structure and mature vessels formation. Administration of 10 mg/kg antibody for up to 35 days resulted in minimal body weight loss and no observations of gross toxicity were made. Collectively, the data obtained with OM-RCA-01 are consistent with potent inhibition of FGFR1-signaling, angiogenesis, and tumor growth. OM-RCA-01 is being developed clinically as an intravenous therapy for the treatment of clear cell RCC. © 2013 Springer Science+Business Media New York. Source

People living in malaria endemic areas develop, with time, a form of immunity to infection and clinical disease mediated by antibodies directed against P. falciparum antigens. Currently there are no assays or clinical parameters that predict whether an exposed person is protected against malaria. This represents a major obstacle for vaccine development. Here research institutions and industrial partners, combining cutting edge expertise in protein microarrays, immunoassay development, immunology, protein expression and epidemiology join their efforts with the objective of translating the genome sequence information of Plasmodium falciparum into a tool to unravel correlates of protection against human malaria. Recombinant P. falciparum proteins, encompassing the repertoire of secreted and surface antigens, will be printed onto microarrays to develop an immunoassay capable of unraveling antibodies directed against a vast number of parasite molecules. This assay will be utilized to compare the antigen-antibody recognition profiles of protected and non-protected persons in malaria-exposed communities, thus facilitating the identification of the antigens that either alone or in combination function as targets of protective immunity. The underlying project structure in terms of research activities, task distribution and management has been planned with the priority of facilitating the interactions of human resources, between academic institutions and industry. Exchange of staff and networking activities will bridge the scientific and cultural differences existing between the academic and industrial partners. Exchange of scientific knowledge and technical skill will unleash the full potential of the collective expertise of the participating laboratories towards the objectives of the proposal and will be instrumental in building collaborative links that will extend beyond the duration of the project.

There is now an increasingly solid body of scientific evidence which demonstrates that the binding of small molecular weight compounds, peptides and antibodies (Abs) to fusion-intermediate conformations of gp41 leads to an inhibition of HIV cell entry. The principal aim of this project is to exploit this information by establishing a platform where gp41-derived vaccine candidates will be designed to elicit neutralising Abs. Several families of immunogens which mimic gp41 in its fusion intermediate conformations are already available and others will be designed using modelisation approaches. Candidates will be submitted to a thorough biophysical characterisation followed by a preclinical development in order to identify the most promising for clinical evaluation. A crucial selection parameter is the capacity of antigens to elicit neutralising Abs using internationally standardized assays. Since sexual transmission accounts for more than 90% of HIV infection, the capacity of Abs to inhibit infection at the mucosal level will also be determined. This cross-disciplinary project gathers top European scientists with expertise in protein engineering and characterisation, adjuvantation, formulation for systemic and mucosal delivery, evaluation of functional antibody response, efficacy testing in animal models, medium to large scale vaccine production as well as conduct of clinical trials in both developed and third-world countries. In contrast to previous more empirical attempts, this project is based on the rational exploitation of the knowledge on the mechanism of HIV entry and is thus a promising approach to generate a protective vaccine. It will be the first European project targeting intermediate conformations of gp41 and it could complement/synergize other international strategies focusing on the membrane proximal region of gp41 or gp140 trimer to induce neutralising Abs or aiming at reducing the viral load by eliciting a cellular immunity against HIV.

Immunity | Year: 2011

Human immunodeficiency virus (HIV)-1 is mainly transmitted mucosally during sexual intercourse. We therefore evaluated the protective efficacy of a vaccine active at mucosal sites. Macaca mulatta monkeys were immunized via both the intramuscular and intranasal routes with an HIV-1 vaccine made of gp41-subunit antigens grafted on virosomes, a safe delivery carrier approved in humans with self-adjuvant properties. Six months after 13 vaginal challenges with simian-HIV (SHIV)-SF162P3, four out of five vaccinated animals remained virus-negative, and the fifth was only transiently infected. None of the five animals seroconverted to p27. gag-SIV. In contrast, all 6 placebo-vaccinated animals became infected and seroconverted. All protected animals showed gp41-specific vaginal IgAs with HIV-1 transcytosis-blocking properties and vaginal IgGs with neutralizing and/or antibody-dependent cellular-cytotoxicity activities. In contrast, plasma IgGs totally lacked virus-neutralizing activity. The protection observed challenges the paradigm whereby circulating antiviral antibodies are required for protection against HIV-1 infection and may serve in designing a human vaccine against HIV-1-AIDS. © 2011 Elsevier Inc.
