Every year, new cancer treatment insights are shared at the American Society of Clinical Oncology (ASCO) Annual Meeting. Here are some of the most notable recent developments in melanoma treatment, gleaned from researchers’ presentations at ASCO last month: Continue reading…
“Rapid resistance to vemurafenib – a treatment for a type of advanced melanoma, the deadliest form of skin cancer – could be prevented by blocking a druggable family of proteins, according to research published in Nature Communications today.
“Scientists at the Cancer Research UK Manchester Institute, based at the University of Manchester, have revealed the MLK family of four enzymes ‘undoes’ the tumour-shrinking effects of vemurafenib.”
Editor’s note: This story describes a potential new way to treat melanoma that has become resistant to vemurafenib. While promising, the research is still in preliminary stages, so new treatments are not yet available for patients.
If you’ve read up on lung cancer research in the last few years, you probably know that large strides have been made in targeted therapies for non-small cell lung cancer (NSCLC). Targeted therapies are drugs that identify and attack specific mutated proteins that are detected in tumors. Because noncancerous cells do not have these specific mutations, targeted therapies can make a beeline for cancer, while leaving healthy tissue unharmed. Continue reading…
“As reported in The Lancet Oncology by Larkin et al, interim results of a safety study designed to reflect the spectrum of patients encountered in routine practice suggest that vemurafenib (Zelboraf) has a safety profile in patients with BRAF V600–mutated metastatic melanoma similar to that observed in the more select patient population included in registration trials. The study included patients with limited treatment options and sizable proportions with brain metastases, elevated lactate dehydrogenase (LDH), poor performance status, and age ≥ 75 years.”
Editor’s Note: The important takeaway from this story is that the drug vemurafenib can be used safely and effectively in some melanoma patients with poor prognoses, who may not fit the profile of patients typically enrolled in clinical trials to test the drug.

“In the BRIM-3 trial, vemurafenib (Zelboraf) was associated with improved progression-free and overall survival vs dacarbazine in patients with advanced BRAF V600 mutation–positive melanoma. In an extended follow-up reported in The Lancet Oncology, McArthur et al found that superior survival outcomes were maintained and were present in both theBRAF V600E and BRAF V600K mutation subgroups.”

The US Food and Drug Administration just granted accelerated approval for a treatment that combines two drugs that target melanomas with BRAF mutations — but this was contingent on the results of an ongoing phase III clinical trial. The drugs are the BRAF inhibitor dabrafenib (Tafinlar) and the MEK inhibitor trametinib (Mekinist). Now the latest results of the trial are in and they look good. This combination treatment is not approved elsewhere in the world, and the trial included 423 people from Australia, Europe, and North and South America. Final results are expected later this year and will be presented at a scientific meeting. In addition, another trial is comparing this combination treatment to the BRAF inhibitor vemurafenib (Zelboraf), which is also FDA-approved.
The past year saw some remarkable advances in melanoma clinical research and treatment. This feature explores the most notable melanoma news of 2013: Continue reading…
