Key takeaways
  • In 2011, the pharmaceutical industry spent between $162-265bn on research.
  • But the industry tends to under-invest in certain areas, such as maternal and neonatal health.
  • Neoplasms carry the same medical weight as neonatal disorders but were the subject of 1,600 clinical trials in 2015, compared with 11 projects for neonatal health.
  • The reasons for this lack of support include regulations, limited knowledge, and financial profitability.
  • One solution is to encourage more public-private partnerships, as was the case for neglected tropical diseases in the 2000s.

It’s an unders­ta­te­ment to say that heal­th­care requires major invest­ment : indeed, the phar­ma­ceu­ti­cal indus­try spends a huge amount eve­ry year pre­pa­ring the solu­tions of tomor­row. And yet, des­pite such huge sums, some sec­tors still suf­fer from under-invest­ment. While this phe­no­me­non of under-invest­ment may be pre­dic­table – cer­tain diseases are beco­ming increa­sin­gly rare – it is more sur­pri­sing when it affects areas such as mater­nal and neo­na­tal health, which are the sub­ject of far fewer pro­jects and cli­ni­cal trials. The rea­son is not, of course, a lack of rele­vance or inter­est in these sub­jects : the research conduc­ted by Pro­fes­sor Sim­cha Jong high­lights the role played by regu­la­tions, the rela­tive lack of know­ledge and expec­ta­tions of limi­ted finan­cial returns in this phe­no­me­non. This research also indi­cates that public-pri­vate part­ner­ships are capable of pro­vi­ding a solu­tion to the under-invest­ment in mater­nal and new­born health research, just as they were use­ful in acce­le­ra­ting research into tro­pi­cal diseases 20 years ago.

Eco­no­mics can become a key fac­tor in public health : this is the hypo­the­sis that has been the focus of our work over the last few years. On the one hand, drugs account for a major pro­por­tion of heal­th­care expen­di­ture. On the other, cer­tain inno­va­tions, such as treat­ment for hepa­ti­tis C, anti­re­tro­vi­rals and can­cer immu­no­the­ra­pies, have the intrin­sic power to mas­si­ve­ly reduce the impact of these diseases on our socie­ties. In 2011, the phar­ma­ceu­ti­cal indus­try spent bet­ween $162–265bn on research1. Encou­ra­ging bio­phar­ma­ceu­ti­cal com­pa­nies to invest in research and deve­lop­ment (R&D) in medi­cal fields with high mor­ta­li­ty and mor­bi­di­ty could the­re­fore reduce the bur­den of these diseases.  Our research sug­gests that public-pri­vate part­ner­ships are an effec­tive tool. Why public-pri­vate part­ner­ships ? Because, left to its own devices, indus­try tends to under-invest in cer­tain disease areas such as mater­nal and neo­na­tal health.

High demands, low investments

Pre­vious work has map­ped medi­cal needs and their impor­tance in terms of glo­bal health2. We have lin­ked this data to the R&D efforts of phar­ma­ceu­ti­cal com­pa­nies for each disease group, the lat­ter para­me­ter being cal­cu­la­ted based on the num­ber of cli­ni­cal trials. More than 62,000 pro­jects were ana­ly­sed, inclu­ding near­ly 11,000 in active (pre)clinical deve­lop­ment as of sum­mer 2015, cove­ring 1,202 dif­ferent diseases. In some cases, there is a clear match bet­ween the impact of the disease and its fun­ding. For example, the bio­phar­ma­ceu­ti­cal indus­try allo­cates R&D resources to pro­jects tar­ge­ting dif­ferent types of can­cer on the basis of the glo­bal impact that these dif­ferent diseases represent. In other cases, there is an imba­lance bet­ween the scale of the health need and the R&D cove­rage : this is the case, for example, with mater­nal and neo­na­tal health problems.

Howe­ver, if we use the num­ber of years lost due to disease as an indi­ca­tor on a glo­bal scale (DALY, for disa­bi­li­ty-adjus­ted life years), we see that neo­plasms, tumours made up of cells that pro­li­fe­rate exces­si­ve­ly, have a simi­lar weight to neo­na­tal disor­ders. But the com­mit­ment to cli­ni­cal research that they gene­rate is in no way com­pa­rable. In the sum­mer of 2015, there were 1,600 cli­ni­cal trials for neo­na­tal tumours, whe­reas for the same per­iod there were only 11 active indus­trial R&D pro­jects for neo­na­tal disor­ders. These child­hood patho­lo­gies are the­re­fore vic­tims of under-invest­ment in R&D. In a per­fect mar­ket, the indus­try’s R&D efforts would be more even­ly dis­tri­bu­ted bet­ween these two cate­go­ries of disease. 

Of course, there are struc­tu­ral rea­sons why bio­phar­ma­ceu­ti­cal com­pa­nies make such lit­tle com­mit­ment to R&D in neo­na­tal and mater­nal diseases. These include the par­ti­cu­lar­ly pro­tec­tive regu­la­to­ry fra­me­work for these popu­la­tions, as well as the dif­fi­cul­ties in buil­ding up a body of detai­led bio­lo­gi­cal know­ledge about these cri­ti­cal per­iods of life. We also need to consi­der the pro­fi­ta­bi­li­ty impo­sed by the indus­trial sys­tem : a treat­ment for can­cer may be sold at a much higher price than its equi­va­lent for mater­nal diseases, because the for­mer affects popu­la­tions that are on ave­rage weal­thier than the lat­ter. Can we cor­rect this imba­lance in incen­tives ? The example of neglec­ted tro­pi­cal diseases shows that it can.

Encouraging public-private sector partnerships

This group of diseases was iden­ti­fied as a health prio­ri­ty by the UN in the ear­ly 2000s. This deci­sion led to mea­sures to encou­rage the crea­tion of public-pri­vate part­ner­ships such as the Medi­cines for Mala­ria Ven­ture and DNDi, as well as invest­ment by public donors in research into these diseases, and gene­ral­ly to a much more attrac­tive and less ris­ky envi­ron­ment, for example by com­mit­ting the inter­na­tio­nal autho­ri­ties to pur­cha­sing a cer­tain quan­ti­ty of anti-mala­rial treat­ments at a pre-defi­ned price. This pro­gramme has been deployed through a wide varie­ty of mecha­nisms that help to reduce R&D risks for these diseases from the point of view of industry.

The indus­try tends to under-invest in cer­tain disease areas such as mater­nal and neo­na­tal health.

This model, devi­sed for neglec­ted tro­pi­cal diseases, has pro­ved its worth. Bet­ween 1975 and 1999 of the near­ly 1,400 com­pounds appro­ved by the health autho­ri­ties, 13 concer­ned neglec­ted and tro­pi­cal diseases. Since then, there are 54 drugs on the mar­ket and 188 the­ra­pies in development.

Could this model be applied to other public health issues ? Europe alrea­dy has a strong R&D poli­cy, as demons­tra­ted by the Hori­zon 2020 and Hori­zon Europe pro­grammes. But when it comes to health, the prio­ri­ties gene­ral­ly focus on Euro­pean health issues. And, as the pan­de­mic has vivid­ly illus­tra­ted, health issues can­not be cove­red by a regio­nal approach. It is the­re­fore in our col­lec­tive inter­est to put in place ambi­tious public fun­ding poli­cies for all the neglec­ted fields of medi­cine. Only then can we hope to encou­rage the deve­lop­ment of new treat­ments for mater­nal patho­lo­gies and neo­na­tal disorders.
