A small phase I study combining the immune checkpoint antibody ipilimumab with the angiogenesis inhibitor antibody bevacizumab showed promising results in advanced melanoma patients in 2011. Now, researchers are continuing to study the combination of immunotherapy and anti-angiogenic agents to understand which patients could best benefit from such a combination. Continue reading…
“Although early cutaneous melanoma is usually curable with surgery, distant metastatic melanoma is an aggressive cancer with a median overall survival time of less than 1 year. In 2012, over 75,000 new melanoma diagnoses were expected and over 9,000 deaths were projected (1). Advances in the understanding of distinct melanoma subtypes as well as melanoma immunobiology have resulted in 2 FDA-approved therapies for metastatic melanoma in 2011: vemurafenib, an inhibitor of mutant BRAF — an oncogene present in approximately 50% of melanomas — and ipilimumab, a monoclonal antibody that targets CTLA-4 (2–4)…”
“The FDA recently approved an anti-CTLA-4 antibody (Iplimumab) for the treatment of metastatic melanoma. This decision was based on Phase III results, which demonstrate that blocking this immune checkpoint provides a survival advantage in patients with advanced disease…”
Unexpected liver toxicity derailed a phase I melanoma trial of concurrent treatment with the first two targeted agents approved for the disease, according to a brief communication from investigators.
