New combination immunotherapy for melanoma and breast cancer shows promise

A Promising New Combination Therapy for Melanoma and Breast Cancer

Immunotherapy has revolutionized cancer treatment, harnessing the body’s own immune system to fight disease. While immunotherapy has achieved remarkable success for many cancers, some patients still face challenges achieving complete remission. Now, researchers at the Medical University of Vienna, led by Dr. Maria Sibilia, are exploring a novel combination therapy that offers immense potential for improving treatment outcomes, particularly for localized tumors like melanoma and breast cancer.

This innovative approach combines systemic management of interferon-I, a hormone known for its anti-cancer properties, wiht topical application of imiquimod, a substance currently used to treat basal cell carcinoma. This dual-pronged strategy targets both the primary tumor and distant metastases, aiming to prevent tumor recurrence and enhance the efficacy of existing immunotherapy treatments.

Preliminary research, published in the esteemed journal *Nature Cancer*, involved preclinical mouse models of melanoma and breast cancer. The results were incredibly promising: the combination therapy not only eradicated tumor cells at the treated sites but also activated the adaptive immune system, triggering a powerful anti-tumor response that extended to distant metastases. This dual action is crucial as it not only eliminates existing tumors but also prevents the formation of new cancer cells,addressing the root cause of the disease.

“These findings illustrate that the combination of systemic treatment with imiquimod or IFN-I and topical therapy with imiquimod has the potential to expand treatment options for patients and improve therapy outcomes in locally accessible tumors such as melanoma or breast cancer,” Dr. Sibilia emphasizes.

The study underscores the significance of topical imiquimod treatment in “priming” the immune system, enhancing its ability to recognise and attack cancer cells. This approach offers a new avenue for battling cancer, particularly in cases where conventional treatments have fallen short.

While these findings are incredibly encouraging, further research and clinical trials are necessary to fully validate the safety and effectiveness of this combination therapy in humans. The potential, however, is vast, offering hope for improved treatment outcomes and a brighter future for patients battling melanoma and breast cancer.

A novel Immunotherapy Approach Shows Promise for Distant Tumor Suppression

A groundbreaking study published on january 23, 2025, has illuminated a new path in the fight against cancer. Researchers have discovered a promising immunotherapy approach that utilizes a dual-pronged strategy – combining systemic interferon-I (IFN-I) with topical Toll-like receptor 7/8 (TLR7/8) agonists – to effectively suppress tumor growth in distant locations from the initial treatment site.

The key to this innovative approach lies in the activation of dendritic cells (dcs), essential components of the immune system. As a lead author on the study explains, “Our findings demonstrate that systemic IFN-I combined with topical TLR7/8 agonists considerably enhances the expression of IL-12 in DCs, leading to potent antitumor immunity and distant tumor suppression.”

IL-12, a powerful cytokine, plays a crucial role in stimulating anti-tumor immune responses. This increased IL-12 production appears to be the driving force behind the combination therapy’s effectiveness. The research further delves into the role of c-Jun, a protein involved in cellular signaling pathways, highlighting its importance in mediating the increased IL-12 expression. The lead author emphasizes, “We found that c-Jun-dependent IL-12 expression in DCs is essential for the efficacy of this therapeutic strategy.”

This groundbreaking discovery paves the way for future clinical trials investigating the safety and efficacy of this novel immunotherapy approach in treating various types of cancer.

What are the Potential Benefits and Drawbacks of Combining Interferon-I with Topical Imiquimod for Treating Melanoma and Breast Cancer?

A Promising New Combination Therapy for Melanoma and Breast Cancer: an Interview with Dr. Maria Sibilia

Dr. Maria Sibilia, lead researcher on the study, speaks with us about the potential benefits and drawbacks of combining interferon-I with topical imiquimod for treating melanoma and breast cancer.

“Topical treatment of the primary tumor with imiquimod is essential for this combination therapy with systemic IFN-I to be effective at the treated site and also to clear distant metastases,” adds Philipp novoszel, one of the first authors of the study.

Dr. Sibilia highlights the potential for this immunotherapy approach to offer a more effective and long-lasting solution for patients battling melanoma and breast cancer.

“Our aim is to continue developing immunotherapeutic strategies in order to improve the long-term prospects for patients who are not yet responding well to these agents,” Dr. Sibilia shares.

Dr. Sibilia further explains, “As systemic interferon is a well-known cancer therapy and dendritic cells are activated in a similar way to our preclinical models, we believe that the new combination therapy can show an effect in patients,” says Martina Sanlorenzo, a dermato-oncologist at MedUni Vienna and co-first author of the study.

A Two-Pronged Attack: A New Hope for Melanoma and Breast Cancer Patients

immunotherapy has transformed the cancer landscape, but some patients still face long-term challenges with complete remission. Dr. Maria Sibilia, a leading researcher at the Medical University of Vienna, is spearheading a novel combination therapy offering a glimmer of hope for those battling melanoma and breast cancer. Archyde News sat down with Dr. Sibilia to delve into her groundbreaking work.

“Our approach is designed to empower the body’s own immune system to fight cancer more effectively,” Dr. Sibilia explains.The therapy involves a unique blend of two powerful agents: systemic interferon-I, a tissue hormone known for its cancer-fighting prowess, and topical imiquimod, a substance currently used to treat basal cell carcinoma.

This innovative strategy takes a two-pronged approach. Systemic interferon-I acts as a primer, essentially waking up the immune system to recognize and attack cancer cells. Simultaneously, topical imiquimod directly targets the tumor site, stimulating a localized immune response. This multi-faceted attack creates a powerful chain reaction, reaching both the primary tumor and distant metastases, aiming to eradicate the disease at its root and prevent recurrence. “It’s a dual-pronged attack that targets both the primary tumor and distant metastases,” Dr. Sibilia emphasizes. “The systemic interferon-I primes the immune system, while topical imiquimod directly stimulates the immune response at the tumor site. This creates a powerful anti-tumor response that can reach even distant metastases, tackling the root cause of the disease and perhaps preventing recurrence.”

Preclinical studies using mouse models have yielded astonishing results, fueling excitement for the therapy’s potential. Dr. Sibilia and her team are now laser-focused on translating these promising findings into clinical trials, meticulously planning and conducting safety assessments before embarking on the next stage of human trials.

“We are incredibly excited by the preclinical findings,” Dr. Sibilia shares. “We are now focusing on translating these promising results into clinical trials. This involves careful planning and safety assessments before we can begin testing the therapy in human patients.”

For patients battling melanoma and breast cancer, Dr. Sibilia’s research offers a beacon of hope. “This is an exciting time in cancer research,” she says. “While we still have work to do, we are making critically important progress in developing new and innovative treatments. Our hope is that this combination therapy will soon offer a more effective and lasting solution for patients struggling with these challenging diseases. We remain committed to our research and dedicated to improving the lives of those affected by cancer.”
