Té múscul la indústria biotech? (3)

Els periodistes busquen trobar notícies positives per explicar. La recerca biomèdica s'ha acabat convertint també en una font barata d'expectatives que obren la porta a nous medicaments. Obren tant la porta que hi ha corrent d'aire des de fa temps.

Llegeixo al diari la gran satisfacció d'un centre de recerca per un article que han publicat a Cancer Cell sobre un test sobre una biòpsia líquida que no és biòpsia sinó una anàlisi d'ADN circulant. I la notícia de veritat és que han decidit no patentar-ho per tal que d'altres ho puguin replicar. I jo ho trobo excel·lent i és el que moltes vegades he demanat que passi. Ara bé, convé seguir-ho d'aprop perquè si hi ha d'altres que se n'aprofiten i ho acaben patentant amb modificacions (que ha passat altres vegades) llavors no anem bé. Perquè acabarem on ja sabem, finançament públic de la recerca a canvi de l'apropiació privada de l'excedent.

I l'exemple de les llicències n'és un altra mostra clara del desgavell. En podem agafar una de recent cap una empresa de matriu xinesa que s'ha fet des de Vall d'Hebron, ANEW Medical. Cotitza al Nasdaq i tot sembla molt nordamericà, quan en realitat no ho és.

Busco quin és l'import rebut per aquesta llicència i no ho sé trobar als estats financers. I com aquesta tantes altres. El problema profund de fons és la manca de transparència en els resultats econòmics de la recerca. Ho dic des de fa anys i crec que ha arribat el moment d'establir una moratòria per no augmentar la inversió pública en recerca fins que no es resolgui aquesta qüestió.

La qüestió no és si té múscul la indústria biotech propera, que ja sabem que no, malgrat que en recerca hi hagi aportacions de qualitat. La qüestió és qui se n'està apropiant en estadis inicials. La paradoxa xinesa és ja la màxima.


PS. Cal dir que el motiu que apareguin tantes notícies també té a veure també amb la recerca de fons per la recerca, és una mostra de l'estratègia de maximitzar pressupostos.

PS. Aprofito per constatar l'inici de la fragmentació assistencial dins els hospitals. L'oncologia ha provocat que es modifiqués la funció de producció i hagi creat un hospital dins l'hospital, amb els seus propis laboratoris i serveis.

El cost d'oportunitat dels preus desmesurats dels medicaments pel càncer (2)

 Cancer medicines: a private vice for public benefit?

El que costa un medicament pel càncer:

Over 23 years of cancer medicine R&D the mean cost in USD of developing a cancer medicine to pharmaceutical companies has been around $4.4 billion. But this hides a huge range of costs from ‘just’ 276 million USD for Dinutuximab for post consolidation therapy for childhood high risk neuroblastoma to 13.4 and 15.8 billion USD, respectively, for Durvalumab (used to treat certain types of bladder, lung, and biliary tract cancer) and Isatuximab (used in treatment of blood cancer multiple myeloma).

I el retorn de la inversió (ROI):

 Overall, ROI for cancer medicines with sufficient maturity i.e., launched between 1997-2015 is between 435 to 551%. Again, this hides huge variation. A substantial number of cancer medicines to date have negative or flat ROI’s as low as minus 78-87% in some cases. However, some cancer medicines launched in late 1990’s to mid 2000 have generated astronomical ROIs; for example, Erlotinib (2794%) (pancreatic and lung cancer), Trastuzumab (3421%) (breast cancer), Rituximab (2523%) (Non Hodgkin’s Lymphoma) and Bevacizumab (3200%) (colon, lung, glioblastoma and renal cell cancers). This reflects the fact the the oncology business model is still driven by blockbusters.

I el missatge:

 The problem thus is that the entire structure and incentive framework governing the biotechnology and pharmaceutical industry are geared towards a specific type of behaviour. Short of completely reforming the entire capital-industrial market, starting in the USA, expecting industry to behave any differently from what it is doing right now is a dead end. It is an ideological and technical cul-de-sac. Arguing about the rights and wrongs of industry profits in oncology misses the point. The system is geared towards profit maximisation that is completely independent of R&D costs, it is insensitive to whether the drugs deliver meaningful therapeutic benefit, or whether the cancer medicines are priced ‘fairly’ for any given country.

Les opcions:

One is faced with two choices. Accept that progress is a private vice with public benefit. Essentially align with Bernard Mandeville’s position in Fable of the Bees (1705) that vicious greed, properly channelled by skilful politics, will lead to invisible co-operation and public benefit. Espousing any higher virtue is mere hypocrisy. In this world the only challenge is external. If, for example, China was to exercise its considerable biopharmaceutical muscle in oncology to massively undercut global prices. The other choice falls more in line with the Rawlsian idea of social justice. In this world a new social contract is constructed that truly reflects equitable value. Respective institutions all align along this common public good backbone. Prices truly reflect clinical benefit and are set to a fair level that maximises patient access. R&D is incentivised on societal worth and not profit.

Article per guardar i per reflexionar. El cost d'oportunitat dels medicaments pel càncer és precisament tot aquest valor social que som incapaços de capturar i que deixem de dedicar a altres usos més valuosos.

CAR-T a preu assequible

Cutting-edge CAR-T cancer therapy is now made in India — at one-tenth the cost

Les teràpies CAR-T són una realitat i han modificat substancialment el curs de tractament del càncer. A la confrontació acadèmia-indústria s'hi afegeix ara un altre actor: Inmuno ACT, a Nature podeu trobar el detall del que representa: oferir el tractament a la desena part del seu cost. Després de l'acord amb l'hospital Clínic, amb Inmuneel (també de la Índia), ara aquesta empresa amb connexions amb el gegant industrial Tata, ofereix un salt rellevant.

NexCAR19 is similar to its US counterparts, yet distinct in key ways. Like four of the six CAR-T therapies approved by the US Food and Drug Administration (FDA), it is designed to target CD19, a marker found on B-cell cancers2. However, in existing commercial therapies, the antibody fragment at the end of a CAR is typically from mice, which limits its durability because the immune system recognizes it as foreign and eventually eliminates it. Therefore, in NexCAR19, Dwivedi and her colleagues added human proteins to the mouse antibody tips.

Tot plegat és l'anunci de la innovació que ve. Estem acostumats a que Índia i Xina siguin subministradors de principis actius genèrics. En realitat s'està teixint la base perquè els medicaments innovadors sorgeixin allà amb agilitat. I no només medicaments, també els subministraments mèdics.

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.
