Small Test Shows Treatment’s Potential to Stop Spread of Melanoma Cancer

Treatment uses drug believed capable of stimulating a patient’s immune system into attacking cancer cells while sparing healthy normal tissue

Nov. 16, 2012 – Most senior citizens know that melanoma is the most deadly skin cancer, if it is not caught early and surgically removed. When it is not detected early and begins to spread it can move very rapidly to other parts of the body, and becomes very difficult to stop. New hope, however, for stopping this cancer was reported recently at an international meeting.

These study findings by a San Diego-based company, OncoSec Medical Inc., while very preliminary, indicate a potential role for OncoSec’s treatment as a safe and effective option for treating melanoma, the company says in a news release.

“Further results from the study will strengthen our understanding of the long-term effects of the treatment, perhaps leading to a new era for those with melanoma,” the company said.

Melanoma is the most serious form of skin cancer. While not the most common skin cancer, melanoma does cause the most fatalities, and most of these are older people. The average age of diagnosis is 61. The American Cancer Society estimates that about 123,000 new cases of melanoma in the US are diagnosed every year, resulting in approximately 10,000 deaths.

If recognized and treated early, it is almost always curable, but if not, the cancer can advance and spread to other parts of the body - in a process called metastasis - where it becomes hard to treat and potentially fatal.

Currently, there are few treatment options for patients with late-stage metastatic disease that can extend survival.

OncoSec Medical is among those who are looking at novel approaches. At the 6th World Meeting of Interdisciplinary Melanoma/Skin Care Centres & 8th EADO Congress the company announced the “positive results” from an ongoing trial investigating its own proprietary treatment in metastatic melanoma patients.

OncoSec’s treatment, known as ImmunoPulse, hinges on two simple facts:

   First, when a small, localized electric current is administered in the vicinity of a tumor - a process called electroporation - tiny holes or pores temporarily open on the surface of the tumor’s cancer cells.

   Second, during the interval when those pores are open, a drug can be absorbed by the cancer cells at effective doses much lower than normal. OncoSec has chosen to use a specific drug in tandem with its treatment - DNA IL-12 - which is believed capable of stimulating a patient’s immune system into attacking cancer cells while sparing healthy normal tissue.

At the time of the new preliminary interim analysis, 13 subjects were evaluable on the 39th day, nine on the 90th day and two on the 180th day. Each patient was treated with DNA IL-12 and underwent electroporation.

The results, according to the company, were the following:

By the 39th day, 95 percent of treated lesions showed some response to the treatment; as measured on the 90th day and again on the 180th day, all treated lesions showed some response to the treatment.

Analysis of the safety data for the patients appeared to confirm that the use of DNA IL-12 with electroporation is safe and well-tolerated.

Furthermore, the analysis provided evidence of a distant lesion response, which is the intent of this type of immunotherapy treatment.

Specifically, the two patients evaluated at 180 days have shown what researchers call “stable disease” (meaning their cancer is neither decreasing nor increasing) and “complete response” (the disappearance of all outward signs of cancer, aka complete remission).

About Melanoma

Melanoma is a form of cancer that begins in melanocytes (cells that make the pigment melanin). It may begin in a mole (skin melanoma), but can also begin in other pigmented tissues, such as in the eye or in the intestines.

It is estimated that 76,250 men and women (44,250 men and 32,000 women) will be diagnosed with and 9,180 men and women will die of melanoma of the skin in 2012.

From 2005-2009, the median age at diagnosis for melanoma of the skin was 61 years of age.

Approximately 0.6% were diagnosed under age 20; 6.8% between 20 and 34; 10.7% between 35 and 44; 18.2% between 45 and 54; 21.6% between 55 and 64; 18.8% between 65 and 74; 16.7% between 75 and 84; and 6.6% 85+ years of age.

The age-adjusted incidence rate was 21.0 per 100,000 men and women per year.

US Mortality

From 2005-2009, the median age at death for melanoma of the skin was 68 years of age. Approximately 0.1% died under age 20; 2.6% between 20 and 34; 5.6% between 35 and 44; 13.5% between 45 and 54; 19.9% between 55 and 64; 21.2% between 65 and 74; 24.1% between 75 and 84; and 12.9% 85+ years of age.

The age-adjusted death rate was 2.7 per 100,000 men and women per year. These rates are based on patients who died in 2005-2009 in the US.

Lifetime Risk

Based on rates from 2007-2009, 1.99% of men and women born today will be diagnosed with melanoma of the skin at some time during their lifetime. This number can also be expressed as 1 in 50 men and women will be diagnosed with melanoma of the skin during their lifetime. These statistics are called the lifetime risk of developing cancer.

Sometimes it is more useful to look at the probability of developing melanoma of the skin between two age groups. For example, 0.99% of men will develop melanoma of the skin between their 50th and 70th birthdays compared to 0.60% for women

Prevalence

On January 1, 2009, in the United States there were approximately 876,344 men and women alive who had a history of melanoma of the skin - 427,810 men and 448,534 women.
