Strategic divide management in pharmaceutical alliances: A partner’s strategic evolution as a reason for strategic divide

Strategic alliances are widely used in the pharmaceutical industry and, ideally, they are long-lasting structures that bring many benefits and value to the alliance partners. However, organizations continuously encounter pressures to enhance performance, while the environment in which they operate evolves. Therefore, an alliance partner might be forced to change its strategy, which can lead to the partners’ misaligned priorities and strategic divide. The academic literature acknowledges the impact a partner’s strategic change can have on the value of the alliance, but the phenomenon is not studied further, which is why the purpose of this study is to understand the role that a partner’s strategic evolution plays in strategic alliances within the pharmaceutical industry. The main purpose is further divided into three sub-objectives: 1) Describe reasons behind the strategic direction change of a partner firm, 2) Understand the consequences of partners’ misaligned priorities, and 3) Describe proactive and reactive ways to manage strategic divide between alliance partners. Since the phenomenon is not studied much, the empirical part of the study was conducted as a qualitative analysis using expert interviews to better understand, how the partner’s strategic evolution affects the alliance. The empirical data was organized into themes, according to the researcher’s interpretations on the interviews. The research findings demonstrated, how the partners change their strategies if the external or organizational environments change. The strategic changes, again, cause strategic divides between the alliance partners that are likely to have an impact on the alliance value. The findings revealed that the interviewees consider anticipation of the partner’s strategic change to be really difficult, but, at the same time, it was noted that a proactive strategic divide management could help to prevent and detect some divides. Additionally, the results showed that, after the detection, a reactive approach in a controlled manner was seen to be the most beneficial for the alliance’s future performance. This study proved that a partner’s strategic evolution affects the partners’ priority alignment and alliance value, which is why the strategic divide management is important in organizations that are involved with strategic alliances. In order to understand the role of a partner’s strategic evolution and provide managers with a tool to manage alliances and strategic divides, the study combined the alliance lifecycle as well as the proactive and reactive approaches to strategic divide, and presented a framework for strategic divide management.

Refocusing regulatory exclusivities: Regulatory data protection and marketing exclusivity as forms of pharmaceutical innovation policy

Protection of innovation in the pharmaceutical industry has traditionally been realised through protection of inventions via patents. However, in the European Union regulatory exclusivities restricting market entry of generic products confer tailored, industry specific protection for final, marketable products. This paper retraces the protection conferred by the different forms of exclusivity and assesses them in the light of recent transparency policies of the European Medicines Agency. The purpose of the paper is to argue for rethinking the role of regulatory data as a key tool of innovation policy and for refocusing the attention from patents to the existing regulatory framework. After detailed assessment of the exclusivity regime, the paper identifies key areas of improvement calling for reassessment so as to promote better functioning of the regime as an incentive for accelerated innovation. While economic and public health analysis necessarily provide final answers as to necessity of reform, this paper provides a legal perspective to the issue, appraising the current regulatory framework and identifying areas for further analysis.

25 years of knowledge creation processes in pharmaceutical contemporary trends

The pharmaceutical industry is knowledge and research-intensive. Due to technological, socio-political and organisational changes there has been a continuous evolution in the knowledge base utilized to achieve and maintain competitive advantages in this global industry. There is a gap in analysing the linkages and effects of those changes on knowledge creation processes associated with pharmaceutical R&D activities. Our paper looks to fill this gap. We built on an idiosyncratic research approach – the systematic literature review – and looked to unearth current trends affecting knowledge creation in international/global pharmaceutical R&D. We reviewed scientific papers published between 1980 and 2005. Key findings include promising trends in pharmaceutical innovation and human resource management, and their potential implications on current R&D practices within the pharmaceutical industry, from managerial and policy-making perspectives.

Desenvolvimento, produção e caracterização de nanocristais de fármacos pouco solúveis

Poorly soluble drugs have low bioavailability, representing a major challenge for the pharmaceutical industry. Processing drugs into the nanosized range changes their physical properties, and these are being used in pharmaceutics to develop innovative formulations known as Nanocrystals. Use of nanocrystals to overcome the problem of low bioavailability, and their production using different techniques such as microfluidization or high pressure homogenization, was reviewed in this paper. Examples of drugs, cosmetics and nutraceutical ingredients were also discussed. These technologies are well established in the pharmaceutical industry and are approved by the Food and Drug Administration.

Os investimentos das indústrias farmacêuticas brasileiras em programas sociais: uma análise dos indicadores sociais de 2006

O objetivo deste artigo é analisar a evolução dos investimentos sociais praticados pelo setor industrial farmacêutico brasileiro. A importância do estudo das políticas sociais criadas por esse importante segmento produtivo deve-se à sua forte influência nas mais variadas definições sobre políticas de saúde, entre elas o conflituoso campo de disputa entre a defesa das patentes por parte das empresas e as tentativas de licenciamento compulsório de medicamentos, por parte do governo. Tomamos como fonte de pesquisa os indicadores sociais de 62 indústrias farmacêuticas, relativos ao ano de 2006, publicados pela Federação Brasileira da Indústria Farmacêutica (Febrafarma), em maio de 2007, sob o título Painel Social, apresentados de três formas: dados gerais sobre o número de programas, valores investidos e o número de pessoas beneficiadas; dados gerais classificados segundo um modelo pré-definido e composto de categorias fixas (saúde, educação, comunidade, valorização da vida, cultura, meio ambiente, voluntariado e outros); e dados individualizados por empresa, com a indicação das ementas de cada programa criado. Buscamos com a reflexão sobre esses indicadores averiguar se eles possibilitam realizar um acompanhamento longitudinal das diretrizes e das proposições relacionadas às ações socialmente responsáveis praticadas pelas indústrias farmacêuticas.

INFLUENCE OF ALTITUDE, AGE AND DIAMETER ON YIELD AND ALPHA-BISABOLOL CONTENT OF CANDEIA TREES (Eremanthus erythropappus)

The heartwood of candeia tree is a source of essential oil rich in alpha-bisabolol, a substance widely used in the cosmetic and pharmaceutical industry. Bearing in mind the economic importance of alpha-bisabolol, this work aimed to evaluate the influence of tree age on the yield and content of alpha-bisabolol present in essential oil from candeia, considering two distinct reliefs and three diameter classes, in Aiuruoca region, south Minas Gerais state. The two distinct reliefs correspond respectively to one section of the stand growing at 1,000m of altitude (Area 1) and another section growing at 1,100m of altitude (Area 2). In each section, 15 trees were felled from among 3 different diameter classes. Discs were removed from the base of each tree to estimate their age by doing growth ring count. Soil samples were taken and Subjected to physical and chemical analysis. The logs were reduced into chips and random samples were taken for distillation to extract essential oil. The method used was steam distillation at a pressure of 2 kgf/cm(2)/2.5 h. The chemical analysis was performed in a gas chromatograph (GC) based on the alpha-bisabolol standard reference. The yield of essential oil from trees in Area I was higher than that from trees in Area 2, with the same pattern of influence for older trees. In Area 2, the alpha-bisabolol content was higher in younger trees. No differences were found between the relevant parameters in relation to diameter classes.

Chitinolytic activity of endophytic Streptomyces and potential for biocontrol

Biological sources for the control of plant pathogenic fungi remain an important objective for sustainable agricultural practices. Actinomycetes are used extensively in the pharmaceutical industry and agriculture owing to their great diversity in enzyme production. In the present study, therefore, we evaluated chitinase production by endophytic actinomycetes and the potential of this for control of phytopathogenic fungi. Endophytic Streptomyces were grown on minimum medium supplemented with chitin, and chitinase production was quantified. The strains were screened for any activity towards phytopathogenic fungi and oomycetes by a dual-culture in vitro assay. The correlation between chitinase production and pathogen inhibition was calculated and further confirmed on Colletotrichum sublineolum cell walls by scanning electron microscopy. This paper reports a genetic correlation between chitinase production and the biocontrol potential of endophytic actinomycetes in an antagonistic interaction with different phytopathogens, suggesting that this control could occur inside the host plant. A genetic correlation between chitinase production and pathogen inhibition was demonstrated. Our results provide an enhanced understanding of endophytic Streptomyces and its potential as a biocontrol agent. The implications and applications of these data for biocontrol are discussed.

Ultra-Fast Gradient LC Method for Omeprazole Analysis Using a Monolithic Column: Assay Development, Validation, and Application to the Quality Control of Omeprazole Enteric-Coated Pellets

A method was optimized for the analysis of omeprazole (OMZ) by ultra-high speed LC with diode array detection using a monolithic Chromolith Fast Gradient RP 18 endcapped column (50 x 2.0 mm id). The analyses were performed at 30 degrees C using a mobile phase consisting of 0.15% (v/v) trifluoroacetic acid (TFA) in water (solvent A) and 0.15% (v/v) TFA in acetonitrile (solvent B) under a linear gradient of 5 to 90% B in 1 min at a flow rate of 1.0 mL/min and detection at 220 nm. Under these conditions, OMZ retention time was approximately 0.74 min. Validation parameters, such as selectivity, linearity, precision, accuracy, and robustness, showed results within the acceptable criteria. The method developed was successfully applied to OMZ enteric-coated pellets, showing that this assay can be used in the pharmaceutical industry for routine QC analysis. Moreover, the analytical conditions established allow for the simultaneous analysis of OMZ metabolites, 5-hydroxyomeprazole and omeprazole sulfone, in the same run, showing that this method can be extended to other matrixes with adequate procedures for sample preparation.

Population pharmacokinetics and pharmacodynamics: An underutilized resource

A meeting was convened in Canberra, Australia, at the request of the Australian Drug Evaluation Committee (ADEC), on December 3-4, 1997 to discuss the role of population pharmacokinetics and pharmacodynamics in drug evaluation and development. The ADEC was particularly concerned about registration of drugs in the pediatric age group. The population approach could be used more often than is currently the case in pharmacokinetic and pharmacodynamic studies to provide valuable information for the safe and effective use of drugs in neonates, infants, and children. The meeting ultimately broadened to include discussion about other subgroups. The main conclusions of the meeting were: 1. The population approach, pharmacokinetic and pharmacodynamic analysis, is a valuable tool both for drug registration purposes and for optimal dosing of drugs in specific groups of patients, 2. Population pharmacokinetic and pharmacodynamic studies are able to fill in the gaps' in registration of drugs, for example, to provide information on optimal pediatric dosing. Such studies provide a basis for enhancing product information to improve rational prescribing, 3. Expertise is required to perform the population studies and expertise, with a clinical perspective, is also required to evaluate such studies if they are to be submitted as part of a drug registration dossier Such expertise is available in the Australasian region and is increasing. Centers of excellence with the appropriate expertise to advise and assist should be encouraged to develop and grow in the region, 4. The use of the population approach by the pharmaceutical industry needs to be encouraged to provide valuable information not obtainable by other techniques. The acceptance of population pharmacokinetic and pharmacodynamic analyses by regulatory agencies also needs to be encouraged, and 5. Development of the population approach to pharmacokinetics and pharmacodynamics is needed from a public health perspective to ensure that all available information is collected and used to improve the way drugs are used. This important endeavor needs funding and support at the local and international levels.

Water diffusion in hydroxyethyl methacrylate (HEMA)-based hydrogels formed by gamma-radiolysis

Polymer hydrogels based upon methacrylates are used extensively in the pharmaceutical industry, particularly as controlled release drug delivery systems. These materials are generally prepared by chemically initiated polymerization, but this can lead to the presence of unwanted initiator fragments in the polymer matrix. In the present work, initiation of polymerization by gamma-irradiation of hydroxyethyl methacrylate, with and without added crosslinkers, has been investigated, and the diffusion coefficients for water in the resulting polymers have been measured through mass uptake by the polymers. The diffusion of water in poly(hydroxyethyl methacrylate) at 310 K was found to be Fickian, with a diffusion coefficient of 1.96 +/- 0.1 x 10(11) m(2) s(-1) and an equilibrium water content of 58%, NMR imaging analyses confirmed the adherance to a Fickian model of the diffusion of water into polymer cylinders. The incorporation of small amounts (0.2-0.5 wt%) of added ethyleneglycol-dimethacrylate-based crosslinkers was found to have only a small effect on the diffusion coefficient and the equilibrium water content for the copolymers.

The phylogeography of African Brazilians

Background/Aims: Approximately four million Africans were taken as slaves to Brazil, where they interbred extensively with Amerindians and Europeans. We have previously shown that while most White Brazilians carry Y chromosomes of European origin, they display high proportions of African and Amerindian mtDNA lineages, because of sex-biased genetic admixture. Methods: We studied the Y chromosome and mtDNA haplogroup structure of 120 Black males from Sao Paulo, Brazil. Results: Only 48% of the Y chromosomes, but 85% of the mtDNA haplogroups were characteristic of sub-Saharan Africa, confirming our previous observation of sexually biased mating. We mined literature data for mtDNA and Y chromosome haplogroup frequencies for African native populations from regions involved in Atlantic Slave Trade. Principal Components Analysis and Bayesian analysis of population structure revealed no genetic differentiation of Y chromosome marker frequencies between the African regions. However, mtDNA examination unraveled considerable genetic structure, with three clusters at Central-West Africa, West Africa and Southeast Africa. A hypothesis is proposed to explain this structure. Conclusion: Using these mtDNA data we could obtain for the first time an estimate of the relative ancestral contribution of Central-West (0.445), West (0.431) and Southeast Africa (0.123) to African Brazilians from Sao Paulo. These estimates are consistent with historical information. Copyright (c) 2008 S. Karger AG, Basel.

Expression of Mycobacterium leprae HSP65 in tobacco and its effectiveness as an oral treatment in adjuvant-induced arthritis

Transgenic plants are able to express molecules with antigenic properties. In recent years, this has led the pharmaceutical industry to use plants as alternative systems for the production of recombinant proteins. Plant-produced recominant proteins can have important applications in therapeutics, such as in the treatment of rheumatoid arthritis (RA). In this study, the mycobacterial HSP65 protein expressed in tobacco plants was found to be effective as a treatment for adjuvant-induced arthritis (AIA). We cloned the hsp65 gene from Mycobacterium leprae into plasmid pCAMBIA 2301 under the control of the double 35S promoter from cauliflower mosaic virus. Agrobacterium tumefaciens bearing the pChsp65 plasmid was used to transform tobacco plants. Incorporation of the hsp65 gene was confirmed by PCR, reverse transcription-PCR, histochemistry, and western blot analyses in several transgenic lines of tobacco plants. Oral treatment of AIA rats with the HSP65 protein allowed them to recover body weight and joint inflammation was reduced. Our results suggest a synergistic effect between the HSP65 expressed protein and metabolites presents in tobacco plants.

Effect of Sodium Cyclamate on the Rat Fetal Exocrine Pancreas: a Karyometric and Stereological Study

The cyclamate, a sweetner substance derived from N-cyclo-hexyl-sulfamic acid, is largely utilized as a non-caloric artificial edulcorant in foods and beverages as well as in the pharmaceutical industry. The objective of this study was to evaluate karyometric and stereological alterations in the rat fetal pancreas resulting from the intraperitoneal administration of sodium cyclamate. The exocrine pancreas of ten fetuses of rats were evaluated, five treated and five controls chosen at random, in which five rats that received from the 10th to 14th days of pregnancy an intraperitoneal daily injection of sodium cyclamate at 60 mg/Kg of body weight during 5 days. At the 20th day of gestation, the animals were removed and weighed, as were their placentas; the length of the umbilical cords also were measured. After the laboratory processing, semi-seriated 6mm cuts stained with haematoxyline and cosine were performed. In seven karyometric parameters (major, minor, and medium diameters, volume, area, perimeter, and volume-area ratio), the increase was statistically significant in the treated group when compared with control group. Stereological parameters showed in the treated group a significant increase in the cellular volume and a significant reduction in the numerical cellular density. These results showed that the sodium cyclamate in pregnant rats led to retardation of fetal development and hypertrophy in the exocrine pancreas of the rat fetuses.

Optical encoding of microbeads for gene screening: alternatives to microarrays

Rapid access to genetic information is central to the revolution presently occurring in the pharmaceutical industry, particularly In relation to novel drug target identification and drug development. Genetic variation, gene expression, gene function and gene structure are just some of the important research areas requiring efficient methods of DNA screening. Here, we highlight state-of-the-art techniques and devices for gene screening that promise cheaper and higher-throughput yields than currently achieved with DNA microarrays. We include an overview of existing and proposed bead-based strategies designed to dramatically increase the number of probes that can be interrogated in one assay. We focus, in particular, on the issue of encoding and/or decoding (bar-coding) large bead-based libraries for HTS.

Biostatistics in Australia: Directions in the new millennium

The Biostatistics Collaboration of Australia (BCA) was formed in response to a shortage of statisticians seeking careers in the medical and health professions. The Collaboration has been successful in developing postgraduate courses (Graduate Certificate, Graduate Diploma and Masters) offered by a consortium of seven Australian Universities. These courses are available through a distance learning medium. The BCA was successful in securing funding from the Federal government to launch these courses, which commenced in March 2001. Two traineeships by the NSW Department of Health have also been awarded and a third is currently advertised. There has been close collaboration with governments, the pharmaceutical industry and research organisations to ensure that course content reflects practical problems and addresses industry needs. A second objective of the BCA is to provide ongoing workshops for practising biostatisticians to enhance professional development. These workshops serve to ring together biostatisticians from both within Australia and the Asia-Pacific region, providing a forum for discussion of current statistical thinking. (author abstract)
