The true story behind “the first effective therapy against pancreatic cancer” by Mariano Barbacid | Science | EUROtoday

More than 100 individuals with pancreatic most cancers have written to the National Cancer Research Center (CNIO) to ask for assist from scientist Mariano Barbacid, who on January 27 summoned all of the media to current the promising outcomes of an experiment with 45 mice. cured. Four employees on the heart verify this avalanche of determined messages and that some sufferers have even come to the door of the establishment in Madrid as of late to attempt to converse with Barbacid. The biochemist disclosed his outcomes on February 2 on essentially the most watched tv program in Spain, The Anthill. The presenter, Pablo Motos, proclaimed: “It’s a miracle.”

Colleagues from his personal heart criticize that Barbacid doesn’t higher clarify his battle of curiosity. He and his colleagues Carmen Guerra and Vasiliki Liaki have utilized for a patent for the business exploitation of their experimental remedy, if it ever turns into a actuality. The three of them and different companions shaped an organization, Vega Oncotargets, in April 2024 to develop the therapy in animals. The firm proclaimed in full show on its web site—till this Friday—that they’ve achieved “the first effective therapy against pancreatic cancer,” however the slogan is way from true.

The group, after receiving a rejection from the distinguished journal Naturerevealed his research on December 2 in PNASfrom the United States National Academy of Sciences. Since Barbacid is an instructional, he has the precise to publish his work fast-track, with a barely extra lax evaluate. That research with 45 mice cured It went unnoticed for nearly two months, till the scientist organized the huge press convention on January 27 in collaboration with the non-public CRIS basis towards most cancers. Then it was world information. One of essentially the most learn newspapers on the planet, The Times of Indiatitled: “A Spanish scientist discovers the cure for pancreatic cancer.”

Barbacid already introduced in 2011, when he was director of the CNIO, that his staff had found a mechanism “that prevents the appearance and development of lung cancer,” in accordance with the title of a press launch. In the identical assertion, he accused the Ministry of Science of slowing down his analysis by stopping the arrival of personal financing. In a harsh response, the division of the then minister, biologist Cristina Garmendia, lamented “the false expectations” generated by Barbacid, “which play with the pain and fear that this disease produces in the population.” The ministry, in an unprecedented shock, warned: “Basic findings made in mice should not be announced as if the transition to a cure in humans were immediate.”

The new research by the Barbacid group exposes the outcomes of a “triple therapy,” which assaults the KRAS protein, a sort of swap that causes a cell to divide, from three completely different sides. Some alterations on this molecule – resulting from smoking, for instance – trigger the cells to run amok, multiply uncontrollably and generate a tumor. The “triple therapy” consists of three experimental medication: daraxonrasib, from the American firm Revolution Medicines; afatinib, from the German firm Boehringer Ingelheim; and SD-36, developed by chemist Shaomeng Wang on the University of Michigan (USA).

The three merchandise used belong to different laboratories, however the Barbacid staff has created the corporate Vega Oncotargets, based mostly in Salamanca, to attempt to invent and patent options just like SD-36 and afatinib, which may be very poisonous to the pores and skin. The “triple therapy” used has achieved full and lasting regression of most cancers in 45 mice, each rodents with their very own tumors induced by genetic engineering and specimens with grafted human tumor cells, however has not been examined with metastasis. This newspaper has tried to contact Barbacid since Thursday, with out success.

EL PAÍS has requested three unbiased specialists from the United States for his or her opinion on the research. Biologist Pawel Mazur, from the University of Texas MD Anderson Cancer Center, emphasizes that “Barbacid is an undisputed leader in pancreatic cancer research” and that his newest article is “one of the preclinical advances [en animales] “It would be more responsible to present this work as a very promising initial step, which could help design future clinical trials.” [en humanos]rather than as a short-term solution for people currently living with pancreatic cancer.”

Biochemist Laura Attardi of Stanford University believes the Barbacid staff’s analysis is “revolutionary.” Alterations within the KRAS protein are behind virtually 90% of pancreatic most cancers circumstances. For many years, this convoluted molecule was thought-about an not possible goal to deal with with medication. However, in 2021, the American pharmaceutical firm Amgen obtained the authorization of sotorasib, an efficient drug towards lung most cancers in individuals who have a particular mutation. The drawback is that tumors develop resistance to those early KRAS inhibitors. “The study of Barbacid, with a triple therapy, circumvents this problem and presents a very exciting new clinical approach,” says Attardi. “It seems very promising. I’m sure it still needs to be optimized, but I think it’s a historic milestone,” says the Stanford researcher.

Biomedical physician Luisa Escobar-Hoyos, from Yale University, additionally applauds “the promising results” of Barbacid, however retains her toes on the bottom. “It is important to highlight that only 10% of clinical trials in patients with pancreatic cancer have resulted in a change in medical practice, despite successful tests in mice,” he highlights. “Therefore, from a scientific point of view, these results are excellent news. From a clinical point of view and for patients, it is important to be cautiously optimistic,” Escobar-Hoyos concludes.

On the Vega Oncotargets firm web site, Mariano Barbacid and Carmen Guerra seem as co-founders. There was additionally a 3rd co-founder, astronaut and biotechnologist Sara García, however her identify disappeared on February 5. García, who works in the identical group on the CNIO, assured by telephone that it was an error and he or she shouldn’t be linked to the corporate. The sole administrator is Gerardo Gutiérrez, the profitable chemist who based Gadea Grupo Farmacéutico – a corticosteroid manufacturing emporium based mostly in Valladolid – in 1991 and bought it for $174 million in 2015 to an American multinational.

Gutiérrez particulars the shareholding on the request of EL PAÍS. He himself and his two sons, by way of the corporate 3-Gutinver, personal 25%. The funding firm of the Government of Castilla y León, Sodical, has one other 25%. A lawyer from Salamanca, 10%. The Hermanos Álvarez Quirós Foundation, 7.5%. The CRIS basis towards most cancers, 5.2%. The CNIO, 5%. And virtually 1 / 4 belongs to the scientists concerned.

Vega Oncotargets nonetheless doesn’t have employees, Gutiérrez acknowledges. “We have everything outsourced,” he explains. The businessman highlights the collaboration with FTherapeutics, a consultancy based by chemist Rafael Ferritto to assist flip concepts into actual medication. The Barbacid group on the CNIO is split into two groups: one, led by astronaut Sara García, is looking for its personal molecule for triple remedy; one other, led by Carmen Guerra, is searching for one other drug for a second flank. The third drug could be daraxonrasib, from the American firm Revolution Medicines.

Gutiérrez presents the present scenario realistically: they haven’t even demonstrated that their very own merchandise work in mice, however they’re optimistic. “We have a couple of molecules that aim very well, but we have to continue polishing them and measuring their toxicity. The probability that this will end well is not high, not to say it is very small, but, if this goes well, we estimate that in two or three years it could begin to be tested on human volunteers,” he maintains. Gutiérrez acknowledges that it was a mistake for the Vega Oncotargets web site to announce “the first effective therapy against pancreatic cancer,” with none certainty that this therapy will exist sooner or later. “We have very promising initial results, but it is very important not to give false hope,” he admits. The firm modified its slogan this Friday. Now it’s: “We are researching to cure pancreatic cancer.”

Pharmacologist Carmen Guerra says that she has acquired about 40 messages from sufferers in her mailbox. The Barbacid one is “totally collapsed,” he confirms. “We did not expect this repercussion, we have tried to make it clear that this is in mice,” he laments. On the PubPeer web site, the place scientists touch upon research by different colleagues, molecular biologist Sholto David has warned that within the article revealed in PNAS There is similar photograph repeated, illustrating two completely different experiments. David, a widely known science detective, has additionally identified what look like two photographs of the identical tumor, introduced as in the event that they had been two completely different tumors. Guerra regrets the errors, however emphasizes that they’re minimal and don’t have an effect on the conclusions in any approach.

The president of the CRIS basis towards most cancers, Lola Manterola, believes that the communication marketing campaign carried out by her entity has been “impeccable, making it clear at all times that the study is in mice.” Manterola herself has attended some interviews with Barbacid, comparable to these carried out in And now Sonsoles and that of The Anthilleach packages on Antena 3. After the presenter Pablo Motos mentioned that “it is a miracle” and after receiving two ovations, the biochemist clarified: “At least in experimental tumors. We must make it very clear that we still have at least two or three years to reach patients.” On this system’s YouTube channel, with 750,000 followers, the video of the interview is introduced with a label added later: “The cure for pancreatic cancer. Historic discovery!”

The CRIS basis towards most cancers, based by Manterola herself after overcoming a number of myeloma, has raised 64 million euros in its 15 years of life to spend money on oncological analysis in public establishments, in accordance with its personal figures. The non-profit group has a dedication of one other 150 million euros for the following 5 years. The Barbacid group has used virtually 11 million euros of public cash, each nationwide and European, since 2018, in accordance with the CNIO. Almost 66% of its financing is public. CRIS towards most cancers has given him about two million euros since 2020.

“Of course all governments have to invest more, but civil society, if it wants things to change, has to get involved,” Manterola urges in a phone dialog. The president says that, upon seeing that completely different initiatives had been rising on the web to ask for cash for Barbacid, her basis determined to start out a fundraising marketing campaign on January 31. In simply six days they’ve already raised 2.3 million euros, with a aim of three.5 million. In his first press convention, the biochemist estimated that 30 million could be wanted to achieve the primary exams in people and decide if it will be value persevering with.

The marketing campaign message focuses on Barbacid: “It has managed to cure pancreatic cancer in mice and now needs our support to cure it in people.” The video is extra ambiguous. The biochemist, wearing a white coat, proclaims: “I am Mariano Barbacid and, as you have seen in all the news, my team and I have achieved the complete and lasting regression of experimental pancreatic cancers; but this is not our goal, our ultimate goal is to be able to cure pancreatic cancer in patients. And, the sooner, the better. That is why I need your help.”
