Vienna Scientists Pioneer New Combination Therapy for Melanoma and Breast Cancer
Revolutionizing Cancer Care: Vienna Scientists Pioneer New Combination Therapy
A Vienna-based research team, spearheaded by Dr. Maria Sibilia, has made a breakthrough in cancer treatment. Their pioneering combination therapy, detailed in leading journal Nature Cancer, targets topically accessible tumors like melanoma and breast cancer, showing remarkable results in both local and distant cancer cells.
The innovative approach marries the tissue hormone interferon-I (IFN-I) with topical application of Imiquimod, an agent known for activating specific receptors in the immune system. In preclinical trials using mouse models of melanoma and breast cancer, this dynamic duo not only decimated cancer cells at the treated sites but also rallied the body’s adaptive immune system to confront even far-flung metastases.
"Our findings suggest that this combination therapy has the potential to greatly expand treatment options for patients with locally accessible tumors," emphasizes Dr. Sibilia, Head of the Center for Cancer Research at the Medical University of Vienna.
Plasmacytoid dendritic cells (pDCs), activated by Imiquimod, play a pivotal role in this process. When oral Imiquimod stimulates pDCs to produce IFN-I, it primes other immune cells in the tumor environment, leading to inhibited blood vessel formation and tumor cell death. Strikingly, this combination therapy also reduced the formation of new metastases and heightened sensitivity to checkpoint inhibitors, demonstrating promise in preventing tumor relapses.
The study’s co-first author, Philipp Novoszel, underscores the importance of topical imiquimod therapy for the combination’s efficacy: "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."
The researchers aim to continue refining immunotherapeutic strategies to bolsters long-term prospects for cancer patients. Given the established use of systemic interferon in cancer treatment and the similitude between their preclinical models and human systems, hopes are high for clinical effectiveness.
"This therapeutic strategy," says Dr. Sibilia, "could significantly enhance treatment outcomes in superficial tumors, resulting in both local cancer cell death and the induction of a powerful T-cell-driven anti-tumor immune response in distant metastases."
This groundbreaking combination therapy utilizing IFN-I and topical Imiquimod offers a promising new avenue for treating locally accessible tumors. By harnessing the power of the immune system, this approach not only destroys cancer cells at the treatment site but also triggers a robust anti-tumor response in distant metastases. The activation of plasmacytoid dendritic cells (pDCs) by topical Imiquimod is crucial for this potent effect.

This groundbreaking research conducted by Dr. Sibilia and her team at the Medical University of Vienna presents a beacon of hope for patients battling melanoma and breast cancer. By harnessing the powerful synergy between IFN-I and Imiquimod, this innovative combination therapy not only eliminates the visible signs of these cancers but also unleashes the body’s own immune system to fight cancer cells throughout the body. This dual-pronged approach substantially transcends conventional treatments, potentially revolutionizing cancer care and offering a new avenue towards long-term remission. Further clinical trials are eagerly anticipated to validate these promising preclinical results and bring this transformative therapy to the hands of patients worldwide.
