The boss of Moderna, Stéphane Bancel, considered it possible with AFP that the therapeutic vaccine developed by the company against skin cancer would be approved as early as 2025, after new positive results announced on Thursday.
“It is believed that the product, in some countries, could potentially be launched under accelerated approval by 2025,” he said in an interview.
This therapeutic vaccine is not intended to prevent the development of the disease like a conventional vaccine, but to treat it once it appears. However, it uses the same principle: helping the patient’s immune system defend itself against the disease.
Therapeutic vaccines today represent real hope in oncology, an “immunotherapy 2.0”, according to Stéphane Bancel. “Immunotherapy 1.0” is notably represented by increasingly used drugs such as Keytruda, developed by Merck (MSD outside the United States and Canada).
This timetable is particularly encouraged by results published by Moderna on Thursday, showing an improvement, over time, in the chances of survival thanks to the treatment which uses messenger RNA technology which has proven effective against COVID-19.
In a trial of around 160 people with advanced melanoma, taking the vaccine at the same time as the anti-cancer drug Keytruda reduced the risk of the disease coming back by 49% over a three-year period. cancer or death, compared to patients treated only with the anticancer drug.
Moderna had already announced two-year monitoring results last year, with a 44% reduction in risks.
“The difference in survival is growing. The more time passes, the more you see that the advantage” of Moderna’s treatment is “significant,” said Mr. Bancel.
A treatment that works for “one in two people”, compared to those who have received “the best treatment on the market”, in oncology, “that’s huge”, he stressed.
“Individualized” treatment
This data could therefore allow, according to him, a launch of the treatment without waiting for the results of a phase 3 trial. This was started in July on more than 1000 people, and recruitment should be completed “in the second half of 2024”.
“At that time, we can begin to have discussions with the regulatory agencies on accelerating the conditional approval of the product,” explained Stéphane Bancel. The condition for confirming the authorization then being “a success of phase 3, which would confirm the data we see today”.
The treatment has already been designated an “innovative therapy” by the United States Medicines Agency (FDA), a status which aims to accelerate its development. The European Medicines Agency (EMA) has also granted it a similar designation (“Priority Medicines”).
In 2020, around 57,000 people died worldwide from a case of melanoma, one of the most serious forms of skin cancer, according to estimates from a recent study.
Moderna’s therapeutic vaccine is developed from mutations read in the DNA of the patient’s tumor — who undergoes surgery to remove it before receiving treatment.
Detect earlier
Thus, more than a personalization of the vaccine, this is an “individualization”, underlined Mr. Bancel. Moderna “physically makes a product” that is made “just for you.”
To prepare for commercialization, the company is building a factory in Massachusetts dedicated to these individualized cancer treatments.
Other types of tumors are also in consideration. The company announced Monday that it was starting a phase 3 trial against lung cancer.
In the future, another key to saving more lives will be early detection of cancer, according to Stéphane Bancel.
He would like to combine studies with the innovative technology of “liquid biopsies”, thanks to which “you can see little pieces of DNA from the tumor in the blood”.
By making it possible to detect cancer earlier, the patient’s immune system would then be less weakened. However, it is on this immune system that therapeutic vaccines rely.
Other companies, such as BioNTech, are also working on individualized therapeutic cancer vaccines.
