SCIENTIFIC DEVELOPMENT OF A PUBLIC-PRIVATE CONSORTIUM


Therapeutic Vaccine against Lung Cancer available to Patients for the First Time

 

• It activates the immune system to attack the tumor. Results were presented at the annual meeting of the American Society of Clinical Oncology that was held in Chicago, United States, May 31st to June 4th.

• Argentina is the world’s first country in which it will be available. It was also approved in Cuba and it has been licensed for 25 countries in the American and Asian continents. Brazil, Mexico, Uruguay and Turkey are closest to initiating the approval process and roll out.

• It is the greatest scientific breakthrough for this type of cancer treatment in the last 10 years to become a drug readily available to patients.

 

BUENOS AIRES, ARGENTINA. Scientists and clinical researchers introduced a ground-breaking therapeutic vaccine, racotumomab (Vaxira®), entailing a new option for non-small cell lung cancer, the most frequent type of lung cancer. It is indicated for advanced stage lung cancer patients that have undergone chemotherapy and radiotherapy treatment as well as those that have had no response to the first line of treatment.


The new vaccine has tripled the number of patients with a two-year survival rate after treatment initiation, according to a study presented at the ESMO (The European Society for Medical Oncology) annual meeting held last year in Vienna, Austria. More results on racotumomab were submitted at the annual ASCO (American Society of Clinical Oncology) meeting in Chicago, USA, from May 31st to June 4th. ESMO and ASCO are the two most relevant international oncology scientific meetings that gather physicians, scientists and the pharmaceutical industry from all over the world. Studies presented at these meetings have to be previously approved by a peer-review committee.

This innovative therapeutic vaccine induces an immune response against tumor cells. For this reason, it received the support from two relevant scientists, independent from the project, who are renowned experts on immunology. “Immunotherapy has nowadays an important place in oncology treatment. The major advantage of this type of strategy is the specific targeting of tumor antigens, which implies less toxicity and side effects compared to conventional therapies. Research on anti-idiotypic cancer vaccines has greatly evolved over the past decades; they are capable of inducing an immune response more robust since it is formed of humoral but also cellular component. These advantages allow foreseeing a bright future for this type of vaccine strategy. The recent release of Vaxira (Racotumomab) is a good example of this progress. I also believe that this development has wider applications that will influence future treatment and therapeutic strategies that will enhance health and well-being,” stated Dr. Christopher Branford-White, Ph.D., Director of the Health Institute at London Metropolitan University, UK.


Also, Dr. Olivera Finn, Ph. D., Leader of the Cancer Immunology Program at the University of Pittsburgh Cancer Institute, USA, said: “Cancer immunotherapy is not associated with the many drawbacks of chemotherapy, radiotherapy and surgery, such as high toxicity, morbidity and short duration. The field of cancer immunotherapy is progressing at an exciting pace giving us hope for the advent of effective treatment modalities that will enhance the quality of life in patients with malignant disease and prolong tumor free survival or lead to complete cures. Vaxira (Racotumomab), monoclonal antibody that serves as an anti-cancer vaccine is a good example of the advance of immunotherapy for cancer.”

On the other hand, biochemist Silvia Gold, director of the Research, Development and Innovation Consortium that developed the drug, explained, “It is a ground-breaking vaccine because we are dealing with a new therapeutic type of drug, which aims at a new target. Nowadays, it provides an alternative treatment to lung cancer patients, and it holds the potential to be studied and applied to other tumors that have this same target.”


This new therapeutic vaccine shall be available in Argentina as of July and it was also approved in Cuba. In addition, it has been licensed in 25 countries in the American and Asian continents under the Vaxira® trademark. In South America, Elea Laboratories shall have the exclusive rights to sell it in Argentina, Eurofarma has the exclusive license in Brazil, and semi-exclusive rights for the rest of the continent. On the Asian continent, Innogene Kalbiotech has the license to roll out the drug in Korea, Taiwan and India, as well as in Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Singapore, Thailand and the Philippines. In Europe and the rest of American and Asian countries, Recombio is the holder of the license. Mexico, Brazil, Uruguay and Turkey are close to roll out. Racotumomab also enjoys patent protection worldwide.


“The therapeutic vaccine has shown very significant results because, in controlled clinical trials, it tripled the percentage of patients with a two-year survival rate after its administration. The objective of the scientific and medical community is to change the paradigm of cancer treatment, for it to become a chronic and controllable disease, by means of different types of targeted therapies, so that patients can have a better quality of life. This is the first new treatment for this indication available to oncologists in ten years,” added doctor Hugo Sigman, CEO of the Insud Group, Recombio partner and founder of the public-private consortium that developed the drug.
Racotumomab is the result of 18 years of work by a public-private research consortium with the participation of over 90 scientists from leading research and cancer treatment scientific institutions in Argentina, such as the Roffo Institute, the University of Buenos Aires, the National Quilmes University, Garrahan Hospital, and the National Council for Scientific and Technical Research together with the Molecular Immunology Center (Havana, Cuba), the originator of this project. It also received the support from the Ministry of Health and the Ministry of Science, Technology and Product Innovation of Argentina.

“The new therapeutic vaccine is administered via an intradermal injection: the first five induction doses are applied every 14 days, and then a maintenance booster shot is repeated every 28 days. The drug has an innovative action mechanism that triggers a specific powerful immune response against ganglioside antigens, such as NGcGM3, only present in tumor cells. This mechanism reduces adverse effects. The identification of the therapeutic target and its action mechanism are a true scientific breakthrough. It stops the formation of new blood vessels that nurture the tumor thus generating a cellular death mechanism described as “oncotic necrosis”,” explains Dr. Daniel Alonso, scientific director of the Research, Development and Innovation Consortium. “It is important to highlight that this therapy is to be combined with existing ones in advanced stages of the disease, and not to be considered a preventive vaccine,” he adds.


Lung cancer is the leading cause of cancer deaths worldwide, with almost 1.38 million deaths per year according to the World Health Organization (WHO), and an 86% mortality rate amongst those affected by the disease. The most common type of lung cancer, accounting for 70% of all cases, is non-small cell lung cancer, for which this new therapeutic vaccine is indicated.
