(BVGH) built and launched a new online Global Health Primer database in 2011.9 Although BVGH produced snapshot reports on subsets of the neglected dis- ease pipeline in 2007 and 2009,10 the new database facilitates tracking of changes in the neglected disease product develop- ment pipeline over time moving forward. In this study, we used the Global Health Primer dataset to identify 348 unique organizations participating alone or in partnerships with each other in the development of 374 drugs and vaccines for 23 neglected diseases. Each developer was categorized by organization type to explore trends in participation across subsets of developers. We demonstrate here that neglected disease product development is being carried out by a broad range of organization types and participation varies greatly depending on the product type, disease focus, and systematic tracking of the neglected disease R&D pipelines over type of organization evaluated.

DEVELOPER PARTICIPATION BY ORGANIZATION TYPE in neglected disease product development, such as the extent For the purposes of this report, we chose to focus on four to which each organization contributes money, employee time, developer categories: academic/research institutions, product physical reagents, know-how, etc. This is particularly true in the development partnerships (PDPs), biotechnology companies, case of products with multiple development partners.

Using this same approach, large pharmaceutical companies were participating in 17% of products in development with lower participation in vaccines as compared to drugs (10% versus 32%, respectively).

Academic/Research Institutions Academic/Research institutions made up the largest number of organizations participating in neglected disease product development (129 out of 348 total unique organizations; Figure 3). They participated in the development of the greatest number of products (162 of 374 products, 43%; Table 2) and the great- est range of diseases with products in development (20 of the 23 neglected diseases included in this study; Figure 6) of any individual developer type.

Product Development Partnerships (PDPs) Although there are a relatively small number of PDPs (26 unique organizations identified in this study), 40% of products in development have at least one PDP developer (149 products; Table 2). Given the emphasis on the PDP model for new fund- ing for neglected disease research and development (R&D) in the last 10 years,12 it is interesting to note that more than half of the products identified here are being developed outside of this R&D model. Figure 12 Product Development Partn ership (PDP) Pipeline by Disease PDPs have products in development for 16 of the 23 diseases 91 33 24 included in this study (Figure 12).

Biotechnology Companies Biotechnology companies make up the second largest number of organizations participating in neglected disease product development (104 out of 348 total unique organizations; Figure 3). These companies participated in the development of 153 of 374 products (41%; Table 2) and 16 of the 23 neglected dis- eases included in this study (Figure 18).
