More than four million people are diagnosed with cancer every year in the Americas, according to the Pan American Health Organization. The institution predicts this figure will continue to rise, surpassing six million by 2045. Yet, the World Economic Forum warns that only 39% of countries finance the basic components of cancer treatment.

Julieta Porta (Argentina, 26) has identified a major lack of personalization in the treatments currently available. “Current therapies fail in 95% of patients with Glioblastoma Multiforme (GBM), one of the most aggressive types of brain tumors. These patients have an average life expectancy of 15 months and suffer severe side effects,” she explains.

In search of a solution, this engineer with a business specialization from Juan Agustín Maza University (Argentina) has developed SphereBio, an initiative focused on creating personalized cancer vaccines. “We use the patient’s own tumor cells to produce modified nanoparticles, OncoSpheres, which carry the tumor’s antigens or signals directly to immune system cells. This triggers a powerful immune response targeted specifically at the patient’s cancer,” she explains.

According to Porta, the personalized approach not only enhances treatment effectiveness but also reduces the likelihood of tumor recurrence. SphereBio’s vaccines can be integrated with other therapies, such as radiation or chemotherapy, as well as with surgery. “This enables more effective disease control, while reducing toxicities and improving the patient’s quality of life,” she adds.

Over the course of her work, many cancer patients have reached out to SphereBio in search of alternative treatment options. “One message read, ‘Hello, my baby is five months old and has a brain tumor. We don’t want to do chemo or radiation because they seem too aggressive.’ Another said, ‘My husband is 47, has already undergone brain surgery, received chemo and radiation, but the tumor keeps coming back.’ These are just a few of the many stories we receive, filled with pain and despair,” shares the founder.

SphereBio was born from this personal drive and has only grown stronger with the recognition of its technology’s potential to change lives. “Our mission is rooted in the urgent need to offer more effective and personalized solutions, so stories like these can have a different ending,” Porta emphasizes.

The Argentinian entrepreneur holds high expectations for this biotech platform. “Our project will contribute to society by improving cancer treatment effectiveness and reducing side effects, ultimately extending and enhancing patients’ lives. Additionally, the expansion of SphereBio will create jobs and production opportunities in the biotech and research sectors, driving innovation and development in this critical area.” Her vision extends beyond cancer: the technology is also being explored for other diseases, including infectious conditions, and to develop platforms for personalized immune system modulation.

Currently, the platform remains in the preclinical research phase and does not yet serve commercial clients. Nonetheless, it is advancing through trials that demonstrate the success of this personalized therapy, offering renewed hope for cancer patients. 

The company was accelerated by MIT Idea2 in 2024 and has received recognition from several innovation programs, including Endeavor WE and Startup Chile Ignite, among others. It is also one of the 10 winners of the WeXchange competition by IDB Lab. SphereBio has established strategic connections with leading institutions such as Mass General Hospital, Brigham and Women’s Hospital, and the Dana-Farber Cancer Institute in the United States. Porta’s research and accomplishments have earned her a spot among MIT Technology Review in Spanish 35 Innovators Under 35.
