Repensar la innovació en medicaments

 Rethinking Innovation in Drugs: A Pathway to Health for All

En un article recent la Mariana Mazucatto insisteix en el seu argument. És prou conegut i alhora encara convé insistir més. Cal reconèixer el paper del finançament públic a la recerca i innovació en nous medicaments. L'exemple de Moderna i la vacuna de la Covid és prou clar i ja l'he explicat anteriorment. Moderna va rebre 1000 milions $ del govern en ajudes per la recerca i alhora va comprar 1500 milions $ en vacunes per a 100 milions de dosis. El total dedicat pel govern nordamericà a la tecnologia de vacunes mRNA va ser de 31.900 milions $.

Els missatges:

  • It is essential to recognize that health innovation emerges from collective intelligence
  • It is imperative to bolster financial commitments to medical research and development, viewing this as a strategic long-term investment rather than a short-term expenditure, and to protect existing budgets
  • It is crucial to leverage procurement mechanisms to shape market opportunities that align with public health needs  

Malgrat que el finançament és imprescindible, cal una nova governança de la innovació. Unes noves prioritats de recerca i una revisió del problema de les patents. Una proposta que ja s'ha fet moltes vegades però que ningú gosa encapçalar. En altres ocasions ja ho he explicat. Malgrat que les regles del mercat són transnacionals, els governs actuen a l'àmbit nacional. S'han creat organismes multilaterals per garantir el comerç mundial però no per a la regulació necessària de la política sanitària. La OMS en aquest sentit i a l'àmbit dels medicaments afegeix poc.

La Mariana Mazucatto resumeix en aquest article la seva posició sobre la innovació al sector farmacèutic. Ho ha dit en altres llocs, però insisteix que cal una nova governança de la innovació. Bàsicament el missatge és que el govern no pot restar passiu com ara. Reprodueixo el paràgraf clau:

While funding is essential, it alone is not the solution. Government should adopt a mission-oriented approach to drug innovation, setting bold goals related to public health that serve to catalyze innovation and investment — goals that prioritize improved patient outcomes, reduction in disease prevalence, and access equity.Achieving such bold goals would necessitate a reform of intellectual property rights. Moreover, it would require a shift in how collaborations between the public and private sectors are structured to recognize that innovation results from a collective effort, valuing contributions from both public and private entities. And it would require governments to foster collaboration across different ministries, thereby avoiding the compartmentalized governance of health. The excessive tendency of governments to outsource key operations has unfortunately weakened these capacities.

La teranyina que sosté la financialització dels medicaments, la salut i la vida (2)

 Sick with “Shareholder Value”: US Pharma’s Financialized Business Model During the Pandemic

Als USA, la Inflation Reduction Act ha obert la caixa dels trons. La possibilitat que el govern pugui negociar els preus dels medicaments finançats públicament ha desesperat a la indústria que ha engegat una campanya de lobby inusual. Es tracta de protegir els preus alts perquè altrament no hi haurà innovació, això diuen. Però malgrat aquesta campanya, fa pocs dies el WP ja deia que no se n'han sortit i que estem propers a grans canvis, que es resumeixen en aquests 6:

1) Drug price negotiation

2) A cap on out-of-pocket spending

3) Lower prices for insulin

4) Free vaccines

5) Inflation penalty for drug manufacturers. 

6) Extra help for the most vulnerable

El govern vol estalviar fins a 100.000 milions $ en aquests propers anys. I destacaria especialment, això de que si volen augmentar el preu més que la inflació (d'aquells medicaments ja en el mercat) hauran de fer descomptes al finançador públic. Dissuasió per tant de provocar preus excessius.

I aquí és on entra Wall Street que ho rebutja de dalt a baix i que ho veu com una amenaça al model de financialització que ha funcionat fins ara. Diuen que fins a 100 medicaments ja no arribaran al mercat. I aquesta amenaça no creïble no és certa perquè sabem això:

Data for the 474 corporations included in the S&P 500 Index in January 2022 and publicly traded from 2012 through 2021 reveal that these corporations distributed $5.7 trillion as share repurchases during the 2012-2021 fiscal years, representing 55 percent of net income, and $4.2 trillion as dividends, an additional 41 percent of net income.

Les recompres d'accions a la borsa per part de les companyies són un 13% superiors al que dediquen a la innovació.


As shown in Table 1, for the decade 2012-2021, distributions to shareholders by the 14 pharmaceutical companies that were among the 474 S&P 500 companies in the database represented 110 percent of net income,7 a larger proportion than the highly financialized 96 percent for all 474 companies. At 55 percent, the stock buybacks of the subset of pharmaceutical companies was the same proportion of net income as the 474 companies, but, at 54 percent versus 41 percent, pharmaceutical dividends as a proportion of net income far exceeded that of all the companies in the dataset. The 14 pharmaceutical companies accounted for 3.1 percent of the revenues of all 474 companies but 6.6 percent of the net income, 6.6 percent of the buybacks, and 8.8 percent of the dividends. The $747 billion that the pharmaceutical companies distributed to shareholders was 13 percent greater than the $660 billion that these corporations expended on research & development over the decade.


En aquest article de Lazonick hi trobareu molts més detalls sobre com ha canviat el model de negoci amb la biotecnologia. Si amb el model anterior el paper de la borsa era el típic de separació de propietat-control, en el nou les opas eren la forma de control per part de fons de capital-risc i després el paper del NASDAQ va oferir opcions d'entrada i sortida que abans no existien. L'article ho explica magníficament, no ho he vist enlloc més. La interacció de les recompres d'accions amb retribució escandalosa als directius de les companyies farmacèutiques esdevé una cosa mai vista a cap altra indústria.


Any 2021, el màxim directiu de Regeneron va ingressar 452 milions de $. No cal dir res més, tota la taula és una desmesura.

Què cal fer segons Lazonick?. El canvi en la regulació de preus és només el primer pas. Cal prohibir la recompra d'accions, deslligar el pagament dels directius dels valors de l'acció a borsa, posar representants dels accionistes al consell, reformar la fiscalitat de les empreses, encoratjar carreres professionals. 

Molta feina per endavant si es vol capgirar la tendència de financialització dels medicaments que vivim. Altrament, un avís, tot el que als USA es disminueixi com ingressos, voldran que sigui compensat amb fons provinents d'altres països. Per tant cal estar alerta als moviments propers i avançar-se als esdeveniments.

I la notícia de l'any ha estat CRISPR:
Vertex and CRISPR Therapeutics’ exagamglogene autotemcel (exa-cel; Casgevy) especially is the first CRISPR–Cas9-based gene editor to secure a green light from the FDA, winning an approval for sickle cell disease (SCD). Exa-cel is an ex vivo gene-edited cell therapy: blood cells are harvested from patients, genetically modified at the BCL11a transcription factor to re-enable fetal haemoglobin production, and then re-infused into patients. The therapeutically upregulated fetal haemoglobin compensates for the defects in β-haemoglobin that cause the diseases. Clinical data shows that the gene therapy has curative potential, although longer-term data are needed to assess the durability of the effect.

When Harvard Medical School and HHMI’s Stuart Orkin and colleagues discovered the role of BCL11a in fetal haemoglobin production in 2008, it was unclear how to drug the transcription factor. The arrival of CRISPR–Cas9 gene-editing system in 2012 provided a path forward for haemoglobinopathies. The development of the programme was “remarkably fast”, said Orkin. “It is a perfect example of how the ecosystem can work.”

Vertex and CRISPR have priced the one-off treatment at $2.2 million. It also requires a harsh preconditioning chemotherapy regimen, to make room for the edited cells. The therapy will consequently remain out of reach for many patients. “This is not the end game,” says Orkin, who has his eye on next-generation gene editors and small molecules that might be more accessible.
PS. Un breu missatge per aquells que mitjançant la seva recerca "obren la porta" a tractaments i ho expliquen al Telenotícies. No n'hi ha cap d'aquesta llista del 2024 ni del 2023 d'aquí sota que sigui un d'ells, la porta segueix oberta, o potser no hi havia porta per obrir. Millor no haver d'estar sentint això sempre, sense explicar-ne el resultat.
