Com el sector públic i filantròpic va arriscar a la recerca de l'edició genètica

Funding CRISPR: Understanding the role of government and philanthropic institutions in supporting academic research within the CRISPR innovation system 

Sabem que la innovació farmacèutica de l'any 2023 ha estat la primera teràpia aprovada d'edició genètica mitjançant CRISPR. Ara Vertex haurà de pagar una llicència de 100 milions pel cap baix a Broad Institute (Harvard) i al competidor Editas Medicine, per poder comercialitzar-la. 

És un bon moment per preguntar-nos quina ha estat la contribució de finançament públic a la recerca, i per tant si cal considerar fins a quin punt el que s'ha patentat privadament s'ha assolit mitjançant recursos públics.

Això a hores d'ara és complicat de conèixer amb estimacions precises. Però mitjançant la revisió de tots els articles publicats i mirant els reconeixements i agraïments han construït aquest graf que explica prou bé d'on han vingut els recursos per a la recerca, i es veu que fonamentalment venen del govern (punts blaus) i de la filantropia (punts vermells). Aquest és la conclusió del graf referit a Harvard:

The bimodal network model of the Broad/Harvard/MIT system was formed by 28 organizations (12 governmental agencies and 16 philanthropic/charitable organizations) and 111 highly cited papers (14 papers on CRISPR as a biological phenomenon and 97 papers on the development of CRISPR/Cas technologies

 Si cliqueu sobre el gràfic en podreu veure millor el contingut: 


Nota: model de xarxa de cofinançament de la recerca CRISPR/Cas més citada al sistema Broad/Harvard/MIT. Aquesta és una xarxa bimodal de papers i fonts de finançament. La mida dels nodes que representen els articles és una funció del nombre de cites rebudes.
Les vores indiquen quines organitzacions van finançar quins papers. Només els nodes que representen els articles més citats del model de xarxa (més de 500 cites) s'etiqueten amb el seu títol i l'any de publicació i les vores amb llum vermella els relacionen amb la seva organització de finançament.
Els nodes blaus representen agències governamentals, mentre que els nodes vermells representen organitzacions filantròpiques/benèfiques. És important especificar que l'agregació de fonts de finançament està limitada per la informació que els autors proporcionen a la secció d'agraïment dels articles. 

The three clusters are supported by the NIH, which occupies a central position
in the network model, but are cofunded by different sets or organizations. The cluster located in the lower right corner of the network model is formed by papers cofunded by the NIH and the Department of Energy (DoE); a second cluster (upper right corner) is cofunded by a set of philanthropic and governmental organizations; and the third cluster (upper left corner) is cofunded by the Howard Hughes Medical Institute (HHMI) together with a set of U.S. military organizations or programs (Figure 3). There is also an important set of papers exclusively funded by the NIH.
the bimodal network model of the UC system was formed by 15 funding organizations (10 governmental agencies and five philanthropic/charitable organizations) and 117 highly cited papers (59 papers on CRISPR as a biological phenomenon and 58 papers on the development of CRISPR/Cas technologies


In the case of the University of California (UC), the cofunding network model (Figure 4) suggests that the top-cited investigations on CRISPR as a biological phenomenon, which is related to the discovery stage of investigation in which the basis of future technologies are built, were mostly supported by the U.S. Department of Energy and the National Science Foundation. A relatively smaller and less cited set of papers was cosupported by the Burroughs Wellcome Fund together with the National Institutes of Health (NIH; Figure 4). On the other hand, the investigations related to the development of CRISPR/Cas technologies at the UC were mostly supported by the NIH together with the National Science Foundation and the HHMI in two respective clusters of papers (Figure 4). There is also an important set of technological development papers funded by the NIH without the participation of other frequent governmental or philanthropic/charitable funding sources
Doncs aquest és el panorama. Resum, no hi hauria CRISPR si no hi hagués hagut inversió pública i filantròpica a la recerca. Desconeixem la magnitud, però sabem les institucions que hi han participat. Malgrat això, s'ha patentat i per tant a hores d'ara és un bé privat finançat públicament o filantròpicament en bona part. I sobretot això ha passat a l'estadi de la recerca on hi ha més risc, he socialitzat el risc i el resultat ha estat apropiat privadament, una altra volta.

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.
