Scientists are finding that patients who respond to the medication are living much longer than originally anticipated, and the drug is being touted as the key to a cure for skin cancer.
Though Turnham was careful to note that the drug represents "nothing close to being a cure," he said that it was moving the world closer to one than ever before. "Melanoma has been a fortress, but we're beginning to see a crumbling of its foundations," he said, adding that, according to these new findings, "at least half of those [with advanced melanoma] will probably be cured within three to five years. It's shocking." Stephen Hodi, director of the Melanoma Treatment Program at Dana-Farber Cancer Institute in Boston, headed the research behind the latest development, conducting the largest analysis yet of ipilimumab and overall survival in melanoma patients. “These results are important to healthcare providers and patients with advanced melanoma since they provide a perspective on long-term survival for ipilimumab patients who are alive after three years of treatment,” Hodi said in a press release. “Our data, which represent the longest follow-up of the largest numbers of patients on any globally approved melanoma therapy, will provide a benchmark for future medicines for advanced melanoma. While melanoma is not the most common type of skin cancer, it is the most fatal, killing an estimated 8,790 people in the United States annually, according to the Skin Cancer Foundation. It's also the No. 1 cancer diagnosis for women in their 20s, and it's on the rise. If the cancer is recognized and treated early, it's almost always curable; if not, it can spread to other parts of the body, where it becomes hard to treat and until now was almost always fatal, with most patients living less than 18 months after diagnosis. The American Cancer Society estimates that about 120,000 new cases of melanoma in the United States are diagnosed in a year. The treatment, ipilimumab, also called “ipi,” and sold in this country as Yervoy, is an antibody that activates the immune system to fight melanoma skin cancer. It was already known that some patients treated with ipi could survive for long stretches. Because of that, Hodi joined with colleagues from Germany, France and the United States to collect data on a total of 4,846 patients from various studies, aiming to look more closely at survival rates. Ipi was the first new melanoma drug approved in many years, Turnham explained—and it was the first ever to show an impact on overall survival rates in melanoma patients, which fueled much hope. "Patients were clamoring like crack addicts on the street," he recalled. "And I know people who were literally at death's door who are alive now because of the drug." But, he explained, not everyone responds to the drug; in fact, there is a 20 percent or greater chance that it will have no effect on a patient. But now, encouraged by the latest hopeful news, scientists can continue to work on ways to get a better rate of response to the drug. That's important not only so that melanoma patients can have a greater chance of living to see a cure, but also so that they can simply live, Turnham said. "If a man has young children and has been alive for six years [with the cancer], he's seen them go from being first-graders to being in middle school," he noted. "There are all those milestones you wouldn't have otherwise had." |

On March 25, 2011, the Food and Drug Administration (FDA) approved a breakthrough melanoma treatment called Yervoy (ipilimumab). Not only is this the first melanoma drug to receive FDA approval in 13 years, but it's the first therapy proven to extend overall survival for advanced stage melanoma patients. According to the best estimates, Yervoy may offer many patients a 2-year survival advantage, with a smaller percentage of patients being virtually cured.
"This is a very exciting time in the field of melanoma," said Perry Robins, MD, President, The Skin Cancer Foundation. "As melanoma incidence continues to rise, we are hopeful that this new therapy will extend life and improve the quality of life for patients with metastatic melanoma."
Melanoma is the deadliest form of skin cancer. When discovered early, it can usually be cured with surgery alone, but once it spreads (metastasizes) throughout the body, treatment options are limited. After decades of frustration for researchers, however, this promising new therapy is providing hope.
Yervoy (Ipilimumab) is a monoclonal antibody, an immune protein that binds to a molecule called CTLA-4 and inhibits it from functioning. CTLA-4 is a kind of brake on the immune system which keeps it from overfunctioning and thus attacking itself; by blocking it, ipilimumab kicks the immune system into higher gear so that it can identify, attack and eliminate melanoma cells.
In a large phase III trial of 676 advanced, inoperable melanoma patients published in 2010 in the New England Journal of Medicine, subjects previously treated unsuccessfully with other agents who received Yervoy or Yervoy plus a melanoma vaccine (gp100) lived on average 32 percent longer and had a 20 percent greater chance (45 percent vs. 25 percent) of surviving one year than those who received gp100 alone. And 24 percent were alive after two years, compared with just 14 percent of those treated with the other therapy. The impact of this trial cannot be overemphasized, as Yervoy was shown to be the first treatment ever to improve overall survival in advanced melanoma patients.
Now, in new study findings just announced, Yervoy was found to increase overall survival in inoperable stage III or stage IV metastatic melanoma patients who had not received prior therapy. The study specifically showed that ipilimumab combined with the chemotherapy dacarbazine increased overall survival, while dacarbazine alone did not. The findings will be submitted to the American Society of Clinical Oncology for potential presentation at its annual meeting in June.
Side effects of Yervoy are related primarily to the overactivation of the immune system, resulting in itching, skin rash and diarrhea. In fact, Yervoy may be more effective in patients who develop these side effects. However, in rare cases more dangerous side effects can occur, so patients are urged to enter studies with physicians well versed in managing its toxicities.
Another notable aspect of the treatment is that even in patients who ultimately see benefits, the disease may initially progress before it stabilizes or the tumor shrinks. For this reason, early clinical trials were at first deemed a failure before patients started to improve.
The medical community is enthusiastic about the approval of this new treatment. It represents a giant step towards the goal of curing this devastating disease.

Doc, here's a new poem of mine for you.
I am sure it's not as "classy, elegant, or holy" as yours,
but, nonetheless, you may like it.
Life Over the Hill
by SNUMA WM
I hope the melanoma drug works as well as they say.
One less worry about the sun exposure.
I hate to paste the darn sun-block lotions on my skin.
Now, if they can figure out the cure
for the gastric and colon cancers.
I hate the darn endoscopic examinations ever so often.
For the last,
I hope they get a better grip on prostatic cancer.
I hate the darn annual rectal exams !!!

Thank you, WM,
As always, you tell it like it is.
As our body wears out and often breaks down,
as our body cells' DNAs every so often fails to control the cells' behaviors,
as our body continues to be bombarded with assaults of all kinds for so many years,
we develop heart attacks, strokes, hypertension, diabetes and cancers.
As I always says to my elderly patients,
the life over the hill eventually requires a full time job to be taken care of.
As long as our brains doesn't wear out, there will be a way and a hope for that.
I like to believe we have a choice.
Either let ourselves become an old cantankerous man,
complaining all the way to the end,
or count all the blessings we've had in our lives,
accepting whatever surprises may be on our way,
thanking Good Lord all the way to the end
all the experiences this life has provided us.
I wish you and all my friends all the bests
through the rest of their journeys.
I love them all.
