UGA compound offers new hope for treatment of painful adult shingles

Researchers at the University of Georgia and Yale University have discovered a compound with the potential to be more effective than existing agents in treating the very painful blisters known as shingles—a condition that affects up to 30 percent of Americans, mostly elderly, and for which no specific treatment exists.

Most adults remember the fever, itchy blisters and possibly tiny scars they experienced as children when they had chickenpox, which is caused by the varicella-zoster virus, or VZV.Unfortunately, that memory can come back—with a vengeance—when they are older. The VZV virus from childhood chickenpox hides in the nerves, emerging most frequently in adults over the age of 60 as a blistering rash on one side of the body. The rate of complications, including nerve pain that can persist for months or years after the shingles attack is gone, also increases with age.

The novel and effective anti-shingles agent called L-BHDA may change that. Rights to the shingles treatment have been licensed to Bukwang Pharmaceutical Company for preclinical investigations by the University of Georgia Research Foundation, Inc. and Yale University.

“We need new options for medications with increased potency and specificity that can treat VZV, including strains that may be resistant to existing drugs,” said medicinal chemist Chung (David) Chu, Distinguished Research Professor of Pharmaceutical and Biomedical Sciences at UGA, one of the inventors of L-BHDA.

A collaboration between Chu and co-inventor Yung-Chi (Tommy) Cheng, the Henry Bronson Professor of Pharmacology at Yale, has resulted in an extensive portfolio of antiviral compounds that target such diseases as HIV, shingles, hepatitis and cancers.

Chu, who is head of the Drug Discovery Group in the UGA College of Pharmacy, said that although there are generic antiviral drugs to reduce the duration and pain of shingles, and a variety of pain medications and topical creams to relieve long-term pain, “They are only moderately effective.We need more effective anti-VZV agents.

“L-BHDA has the potential to be more effective than existing agents,” said Chu. He noted that the new compound has been tested in the laboratory and demonstrated in mice models by a group of researchers headed by Jennifer Moffat, associate professor of microbiology and immunology, State University of New York Upstate Medical University.

A vaccine to prevent shingles, available to older adults since 2006, can cut the likelihood of a shingles attack in half. However, according to a recent study in the American Journal of Preventive Medicine, only a small percentage of older people receive the shot, principally because of cost, lack of insurance reimbursement and shortage of supply.

It is likely that immunization against chickenpox during childhood also protects against shingles, because the vaccine uses a weakened strain of the virus. However, the vaccine was only introduced in 1995, and there are not enough data to provide a definitive answer.

“Dr. Chu and Dr. Cheng have been working diligently to fill a much needed gap in the treatment options for such a prevalent disease,” said Rachael Widener, UGARF technology licensing manager. “Before the chicken pox vaccine became widely used in the mid-1990s, older, unvaccinated individuals would have their immunity boosted naturally.

“Now, with less exposure to chicken pox, shingles is becoming more prevalent,” said Widener. “This, combined with the aging baby boomer population, underscores the need for more directed treatment. We are hopeful that L-BHDA will allow patients to get well sooner and feel less pain, and will lessen their chances of complications.”

FDA approves Rituxan to treat two rare disorders

The U.S. Food and Drug Administration today approved Rituxan (rituximab), in combination with glucocorticoids (steroids), to treat patients with Wegener’s granulomatosis (WG) and microscopic polyangiitis (MPA), two rare disorders that cause blood vessel inflammation (vasculitis).

Vasculitis in patients with WG and MPA can lead to tissue damage. WG mostly affects the respiratory tract (sinuses, nose, trachea, and lungs) and kidneys, while MPA commonly affects the kidneys, lungs, nerves, skin, and joints. Both of these diseases affect people of all ages and ethnicities, and both genders. The causes of these disorders are unknown, and both are considered orphan diseases because they each affect less than 200,000 people in the United States.

“This new indication for Rituxan provides the first approved therapy for these two orphan diseases,” said Curtis Rosebraugh, M.D., M.P.H., director of the Office of Drug Evaluation II in the FDA’s Center for Drug Evaluation and Research.

Rituxan is an antibody that is manufactured through biotechnology methods. The drug works by greatly reducing the number of specific immune cells in the blood, known as B cells.

The safety and effectiveness of Rituxan was demonstrated in a single controlled trial, in which 197 patients with WG or MPA were assigned at random to receive either Rituxan plus glucocorticoids once a week for four weeks or oral cyclophosphamide plus glucocorticoids daily to induce remission. After six months, 64 percent of patients treated with Rituxan had complete remission compared to 53 percent of patients treated with cyclosphosphamide.

Retreatment with Rituxan was not formally evaluated; therefore, the safety and efficacy of retreatment with subsequent courses of Rituxan has not been established. More data are needed to determine the safety of more than one course of Rituxan and long term safety of use of Rituxan in patients with WG and MPA. These questions will be further evaluated in a required post-marketing study.

Rituxan carries a Boxed Warning for infusion reactions, which can occur during infusion or within 24 hours afterwards. Other Boxed Warnings for Rituxan include rashes and sores in the skin and mouth (severe mucocutaneous reactions); and progressive multifocal leukoencephalopathy, a brain infection that generally is fatal. Rituxan is not recommended for use in patients with severe, active infections.

The most common side effects in study participants with WG and MPA included infection, nausea, diarrhea, headache, muscle spasms, and anemia.

Rituxan, which has been marketed since 1997, is also indicated for the treatment of patients with non-Hodgkin’s lymphoma, chronic lymphocytic leukemia, and rheumatoid arthritis.

Rituxan is manufactured by San Francisco-based Genentech, a member of the Roche Group.

FDA approves Actemra to treat rare form of juvenile arthritis

The U.S. Food and Drug Administration today approved Actemra (tocilizumab), given alone or in combination with methotrexate, for the treatment of active systemic juvenile idiopathic arthritis (SJIA) in children ages 2 years and older.

SJIA, or Still’s disease, is a rare, potentially life-threatening disorder in children that causes severe inflammation throughout the body. SJIA is distinguished from other forms of juvenile idiopathic arthritis (JIA) by the prominence of systemic and inflammatory features, including spiking fevers; rash; swelling and inflammation of lymph nodes, liver, and spleen; and high white blood cell and platelet counts. The prevalence of JIA is an estimated 1 to 2 per 1,000 children, and SJIA affects about 10 percent of all JIA patients.

Actemra is an interleukin-6 receptor blocker approved by the FDA on Jan. 8, 2010, for treatment of adults with moderately to severely active rheumatoid arthritis who have had an inadequate response to other approved therapies.

“This new indication of Actemra provides the first approved therapy for children with this rare disease,” said Badrul Chowdhury, M.D., Ph.D., director of the Division of Pulmonary, Allergy, and Rheumatology Products in the FDA’s Center for Drug Evaluation and Research.

An international, multicenter controlled trial demonstrated the safety and effectiveness of Actemra, in which 112 patients received either Actemra infusions or placebo infusions every two weeks. Study participants included patients with SJIA aged 2 to 17 years old who had inadequate response to or who were unable to take nonsteroidal anti-inflammatory drugs and corticosteroids.

Eighty-five percent of those receiving Actemra responded to treatment, compared with 24 percent of patients receiving placebo. Response was defined as at least 30 percent improvement in the American College of Rheumatology’s JIA efficacy variables, along with absence of fever in the preceding seven days. In the long-term, follow-up period of the trial there were three cases of macrophage activation syndrome (MAS) among SJIA patients receiving Actemra. MAS is a potentially fatal complication of childhood systemic inflammatory disorders, thought to be caused by excessive activation and proliferation of certain immune cells.

Actemra carries a Boxed Warning for serious infections. Patients treated with Actemra who develop a serious infection should stop Actemra treatment until the infection is controlled. A Boxed Warning is a brief, concise summary of the information that is critical for a prescriber to be aware of, including any restriction on distribution or use, which is included in a black box at the beginning of the drug label.

Changes in certain laboratory test results such as liver tests, blood counts, and cholesterol are not uncommon with Actemra and should be monitored with regular blood tests. The most common side effects in trial participants with SJIA included upper respiratory tract infection, headache, sore throat, and diarrhea.

Actemra is marketed by San Francisco-based Genentech Inc., a subsidiary of the Roche Group.

Doctors Recommend Different Treatments for Patients Than for Themselves

A patient who can't decide between two available treatments asks his doctor: "What should I do?" Another patient, torn between the same two treatments, asks: "Doctor, what would you do if you were me?"

Will those two patients get the same answer? That question, posed by researchers from Duke University and the University of Michigan in a national survey of physicians, found doctors often recommend different treatments for patients than they would choose for themselves.

The study, from professor Peter Ubel and post-doctoral associate Andrea Angott of Duke University's Fuqua School of Business and professor Brian Zikmund-Fisher of the University of Michigan, appears in the April 11 edition of the Archives of Internal Medicine. Funding for the study was provided by the American Cancer Society, the National Science Foundation and the National Institutes of Health.

In the study, the researchers conducted a randomized experiment asking some physicians to make a recommendation to a patient seeking advice, while other physicians were asked what they themselves would choose as a patient facing the same health care decision.

Doctors frequently advised patients to pursue treatments with higher rates of side effects and lower mortality rates, while choosing treatments with lower rates of side effects and higher mortality rates for themselves.

"Our research found that people felt living with a colostomy or being paralyzed was better than dying. From that perspective, the ‘right' decision is to take the risk of side effects and reduce the chances of dying," Ubel said.

However, emotions brought on by potential significant side effects often push people away from the "right" decision. Doctors -- free from the side effects of treatment -- can make more objective treatment recommendations to their patients.

"When making recommendations to patients, physicians can push aside any emotions that would lead them astray," Ubel said. "But those emotions may loom large when a doctor is deciding for him or herself. In other words, the act of giving advice to others may reset the balance between emotion and reason."

Ubel noted, "Many physicians are biased by their own backgrounds, valuing things that patients don't necessarily value, or they can even be influenced by financial and professional conflicts of interest that can skew judgment."

As a result, you might not always get the objective advice you seek, Ubel said. "Instead, the advice you get could depend on whether your doctor is thinking about what you should do, or instead thinking about what he or she would do in your situation."

A detailed report on the research is available at http://archinte.ama-assn.org/.

FDA approves new treatment for large brain aneurysms

The U.S. Food and Drug Administration has approved the cPAX Aneurysm Treatment System for surgery on brain aneurysms that are difficult to manage because of their size and shape.

An aneurysm is a bulge in the wall of a blood vessel, which can rupture as it increases in size, causing hemorrhage or death. Brain aneurysms often produce no symptoms until they grow and press on nerves in the brain, or until they begin to leak blood or rupture.

Aneurysms can be repaired in two ways: surgeons can close the base of the aneurysm with a surgical clip, or use a technique commonly known as coiling, in which surgeons use a catheter to thread metallic coils through a blood vessel in the groin and into the blood vessel in the brain that contains the aneurysm. Surgeons then fill the aneurysm with the detachable coils, which block it from circulation and cause blood to clot, effectively destroying the aneurysm.

Aneurysms larger than 10millimeters are difficult to treat with clipping or coiling. The cPAX Aneurysm Treatment System is indicated for use in those brain aneurysms.

“Like coiling, the cPAX Aneurysm Treatment System is a form of endovascular repair,” said Christy Foreman, director of the Office of Device Evaluation in the FDA’s Center for Devices and Radiological Health. “But instead of tiny metallic coils, it uses a special polymer material to fill the space within the aneurysm.”

The cPAX polymeric filler material can be secured in the aneurysm in one of two ways, either by insertion through openings in a permanent stent, which is a tiny metal scaffold placed along the vessel wall, or by using a temporary balloon catheter to block off the opening to the aneurysm and keep the filler material from coming out of the aneurysm as it is being delivered.

By filling the bulging space within the aneurysm with implant material, the blood flow through the aneurysm is stopped and any remaining space around the implant material clots. When filled with implant material and blood clot, and the risk of rupture of the aneurysm decreases.

The cPAX Aneurysm Treatment System was approved on April 1, 2011, under a Humanitarian Device Exemption (HDE). The HDE makes medical devices available to patients with rare medical conditions that affect fewer than 4,000 people a year. The approval for this HDE was based on safety data from two studies of 43 subjects.

The cPAX device system is indicated for use in adults ages 22 and older and should not be used in patients with an active infection or in those in whom anticoagulation and antiplatelet therapy is contraindicated.

The cPAX Aneurysm Treatment System is manufactured by Neurovasx Inc., Maple Grove, Min.

Expansion of HIV/AIDS Vaccine Program Announced by GeoVax Labs, Inc.

/PRNewswire/ -- GeoVax Labs, Inc. (OTCQB/OTCBB: GOVX), announced today that it is expanding its preventative HIV/AIDS vaccine development effort in collaboration with the National Institute of Allergy and Infectious Diseases (NIAID), part of the U.S. National Institutes of Health (NIH) and the HIV Vaccine Trials Network (HVTN). Specifically, the HVTN plans to clinically test a novel vaccine product developed by GeoVax scientists that expresses human granulocyte-macrophage colony stimulating factor (GM-CSF) in combination with inactivated HIV proteins. The novel vaccine consists of a recombinant DNA vaccine co-expressing human GM-CSF and non-infectious HIV virus-like-particles. The DNA vaccine is used to prime immune responses that are subsequently boosted by vaccination with a recombinant modified vaccinia Ankara (MVA) vectored vaccine. The MVA expresses the HIV virus-like-particles, but does not express GM-CSF. The regimen builds on the GeoVax DNA/MVA vaccine that is currently in Phase 2a clinical testing through the HVTN.

GM-CSF is a cytokine (growth stimulating protein) that serves to expand and mature cells that initiate immune responses and has undergone extensive testing in humans for cancer vaccines. The GM-CSF-adjuvanted vaccine was added to GeoVax's portfolio because of the outstanding ability of the simian prototype vaccine to induce immune responses that prevented simian immunodeficiency virus (SIV) infection. In nonhuman primates, the GM-CSF enhanced vaccine achieved protection against SIV in 70% of the animals. Protection was measured against 12 weekly rectal challenges using a dose of SIV which is estimated to be 30 to 300 times higher than the typical exposure dose of HIV in mucosal transmission in humans.

"For years, the HIV vaccine field has been working with vaccines that elicited immune responses that primarily controlled immunodeficiency virus challenges in infected animals, but did not actually prevent infections. The ultimate goal is to prevent infections. The co-expression of GM-CSF with the SIV proteins is a vaccine design that appears to be a large step towards reaching this goal," said Dr. Harriet Robinson, Chief Scientific Officer at GeoVax. "In our trials in nonhuman primates, GM-CSF enhanced the quality of the SIV-specific antibody response. Antibody is present in blood and tissues and has the potential of blocking SIV before it infects cells. The GM-CSF-adjuvanted vaccine induced the production of antibodies characterized with increased tightness of antibody binding. The tightness of antibody binding, known as avidity, can be expressed as an index. Animals with indices above 40 were protected from infection, whereas animals with lower indices were infected with the number of challenges to infection correlating with their index."

"We are very pleased that the HVTN will be conducting trial HVTN 094 of our GM-CSF adjuvanted vaccine product, which we expect will begin late this year," said Dr. Robert McNally, CEO of GeoVax. "The HVTN, funded by the NIAID, is the largest worldwide clinical trials network dedicated to the development and testing of HIV/AIDS vaccines. We are looking forward to working with an excellent team of HVTN trial investigators."

FDA Permits Marketing of First Test to Help Diagnose Dengue Fever

/PRNewswire/ -- The U.S. Food and Drug Administration today allowed marketing of the first test to help diagnose people with signs and symptoms of dengue fever or dengue hemorrhagic fever, a leading cause of illness and death in the tropics and subtropics.

The dengue virus is transmitted to humans by the bite of an infected Aedes mosquito. As many as 100 million people worldwide are infected by the virus each year, according to the U.S. Centers for Disease Control and Prevention (CDC).

Symptoms of dengue fever include high fever, severe headache, severe pain behind the eyes, joint pain, muscle and bone pain, rash and mild bleeding involving the nose or gums, and easy bruising.

Most reported dengue cases in the continental United States occur in people returning from travels to tourist destinations in Latin America, the Caribbean and Southeast Asia. Dengue is also endemic in the U.S. in Puerto Rico, the Virgin Islands and some U.S.-affiliated Pacific Islands. Recently, dengue outbreaks have occurred in Hawaii, Texas, and Florida.

The DENV Detect IgM Capture ELISA test detects antibodies to dengue virus in blood samples from patients who have signs and symptoms of dengue. The test will be available for use in clinical laboratories and will assist in the diagnosis of dengue, which can improve patient care and management.

The DENV Detect IgM Capture ELISA test is based on technology patented by the CDC and manufactured by Seattle-based Inbios Inc.

"Cases of dengue fever or dengue hemorrhagic fever can be potentially fatal for people who do not recognize the symptoms," said Alberto Gutierrez, Ph.D., director of the Office of In Vitro Diagnostics Device Evaluation and Safety in FDA's Center for Devices and Radiological Health. "This test will now aid health care professionals in their effort to more effectively diagnose dengue."

The FDA reviewed data for the test via the "de novo" pathway, an alternative path to market for devices that are low to moderate risk and may not require premarket approval (PMA), but are of a new type, and therefore may not be able to be cleared in a "510(k)" premarket notification.

People who believe they have dengue should immediately contact a health care professional. There are no FDA-licensed vaccines to prevent dengue and no medicines specifically approved to treat the infection.

The test should not be used in people who do not show signs or symptoms of dengue. Diagnostic testing for dengue is complicated by the fact that an IgM antibody response to the dengue virus infection is not detectable until 3-5 days after the onset of fever, which can produce a negative test result even though a person has dengue. During this "IgM negative window" the dengue virus is present in the bloodstream.

There are currently no FDA-cleared or approved tests for direct detection of dengue virus.

This new test shows cross-reaction with other closely related viruses such as those that cause West Nile disease. However, in most patient testing situations found in the United States, a positive test result in a patient with signs or symptoms consistent with dengue should be considered presumptive evidence of dengue.

FDA approves Horizant to treat restless legs syndrome

On April 6, the U.S. Food and Drug Administration approved Horizant Extended Release Tablets (gabapentin enacarbil), a once-daily treatment for moderate-to-severe restless legs syndrome (RLS).

RLS is a disorder that causes a strong urge to move the legs. This urge often occurs with unpleasant feelings in the legs. People who have RLS describe feeling pulling, itching, tingling, burning, or aching in their legs, and moving the legs temporarily relieves these feelings. The urge to move often happens when a person is inactive, and the symptoms typically are worse in the evening and early morning.

“People with restless legs syndrome can experience considerable distress from their symptoms,” said Russell Katz, M.D., director of the Division of Neurology Products in the FDA’s Center for Drug Evaluation and Research. “Horizant provides significant help in treating these symptoms.”

The effectiveness of Horizant was studied in two 12-week clinical trials in adults. The trials showed that people taking the medication had an improvement in their RLS symptoms, compared with people taking an inactive pill (placebo).

Horizant will be dispensed with an FDA-approved Medication Guide that explains the drug’s uses and risks. Horizant may cause drowsiness and dizziness and can impair a person’s ability to drive or operate complex machinery.

Horizant contains gabapentin enacarbil that becomes gabapentin, a drug used to treat seizures in people with epilepsy, when absorbed into the body. All drugs used to treat epilepsy carry warnings that they may cause suicidal thoughts and actions in a small number of people. Horizant will have the same warning.

Horizant was developed by GlaxoSmithKline of Research Triangle Park, N.C., and Xenoport of Santa Clara, Calif.

FDA approves new treatment for rare form of thyroid cancer

The U.S. Food and Drug Administration today (April 6) approved vandetanib to treat adult patients with late-stage (metastatic) medullary thyroid cancer who are ineligible for surgery and who have disease that is growing or causing symptoms.

Thyroid cancer is a cancerous growth of the thyroid gland, which is located in the neck. Medullary thyroid cancer involves specific types of cells that are found in the thyroid gland and can occur spontaneously, or be part of a genetic syndrome.

About 44,600 new thyroid cancer cases were diagnosed in the United States during 2010, and about 1,690 people died from the disease, according to the National Cancer Institute. Medullary thyroid cancer is estimated to represent 3 to 5 percent of all thyroid cancer; its estimated incidence in the United States for 2010 is about 1,300 to 2,200 patients, making it one of the rarer forms of thyroid cancer.

Common symptoms of medullary thyroid cancer may include coughing, difficulty swallowing, enlargement of the thyroid gland, swelling of the neck, a lump on the thyroid, and changes in a person’s voice or hoarseness.

Vandetanib targets medullary thyroid cancer’s ability to grow and expand. There are currently no FDA-approved treatments for this type of cancer. Vandetanib is administered orally on a daily basis.

Vandetanib’s safety and effectiveness were established in a single, randomized international study of 331 patients with late-stage medullary thyroid cancer. Patients in the study were selected to receive vandetanib or placebo (sugar pill).

The study was designed to measure the length of time a patient lived without the individual’s cancer progressing (progression-free survival). Patients who received vandetanib had a longer period of time without disease progression when compared to patients receiving placebo. Median progression-free survival was 16.4 months in the placebo arm and at least 22.6 months in the vandetanib arm. It is too early to determine the median progression-free survival in patients treated with vandetanib or to tell whether they will live longer (overall survival) compared to patients treated with placebo.

“Vandetanib’s approval underscores FDA’s commitment to approving treatments for patients with rare and difficult to treat diseases,” said Richard Pazdur, M.D., director of the Office of Oncology Drug Products in the FDA’s Center for Drug Evaluation and Research.

Common side effects occurring from vandetanib use include diarrhea, rash, nausea, high blood pressure, headache, fatigue, decreased appetite, and stomach (abdominal) pain. Serious side effects reported during the study resulted in five deaths in patients treated with vandetanib. Causes of death included breathing complications, heart failure, and a bacterial infection in the blood (sepsis).

Vandetanib was shown to affect the electrical activity of the heart, which in some cases can cause irregular heart beats that could lead to death. Vandetanib is being approved with a Risk Evaluation and Mitigation Strategy (REMS) to inform health care professionals about these serious heart-related risks. Only health care professionals and pharmacies certified through the vandetanib REMS program, a restricted distribution program, will be able to prescribe and dispense the drug. Patients will also receive an FDA-approved Medication Guide informing them of the potential risks.

Vandetanib is marketed by AstraZeneca Pharmaceuticals LP of Wilmington, Del. There is no trade name established for this drug at this time.

Newborn Possibilities Fund Awards Grant to Georgia Health Sciences University Foundation to Support Groundbreaking Pediatric Research

/PRNewswire/ -- The Newborn Possibilities Fund, a grantmaking program established by Cord Blood Registry (CBR), today announced it will provide its first-ever grant to the Georgia Health Sciences University Foundation. The university's medical center is conducting the first FDA-regulated clinical trial evaluating cord blood stem cells as a medical intervention for cerebral palsy. The grant will provide financial support to help curb travel and other expenses for families with a child participating in the trial.

The study will include 40 children, ages 1 to 12 and will begin with a neurological exam. Then, half of the study participants will receive an infusion of their own cord blood while the other half receives a placebo. Three months later, the children will be evaluated without physicians knowing which group received the stem cell infusion. Afterward, children who didn't get their cord blood initially will receive an infusion. Children in the study will return three and six months later for evaluation, where researchers will assess their motor skills and neurological development.

"This is a very well-designed clinical study that will provide new insights into the potential of cord blood stem cells to help children recover from nerve tissue damage to the brain," said Heather Brown, vice president of scientific and medical affairs at CBR. "However, the study design requires a family to make trips at their own expense to the study center. The goal of The Newborn Possibilities Fund is to remove financial barriers that may prevent eligible children from participating in this cutting-edge research and receiving investigational treatments that may improve their quality of life."

The Newborn Possibilities Fund (NPF) was created to help advance clinical research investigating the use of a child's own cord blood stem cells as a treatment for conditions like cerebral palsy and traumatic brain injury. The NPF directs financial grants to non-profit organizations to help cover the cost of travel for families who have the chance to participate in FDA-regulated trials. The Fund is administered by Tides, a public charity, on behalf of CBR.

Patients who meet the inclusion criteria and are enrolled in the trial at Georgia Health Sciences University will be notified of the Newborn Possibilities Fund and have the opportunity to receive funds to use toward the cost of travel to Augusta, Georgia for the cord blood infusion procedure and required follow up visits.

"The hope for stem cells, really from the beginning, is that they might serve as some type of replacement for cells in the nervous system that have been destroyed or never developed properly," said Dr. James Carroll, professor and chief of pediatric neurology at Georgia Health Sciences University and principal investigator on the study. "The main goal of our research is to try to help improve the lives of children with cerebral palsy and find out if the method we're using is going to help these children in the future."

A growing body of research in animals has shown that infused stem cells help to initiate repair and induce healing in the brain. While the Georgia Health Sciences University is the first controlled clinical trial to be conducted, anecdotal reports from previous studies have shown marked improvement in children with cerebral palsy about three months after an initial infusion of cord blood, which led Dr. Carroll to design his trial.

Through generous donations, the Newborn Possibilities Fund hopes to provide financial support for additional trials already underway at leading research universities across the country. For more information on the program or to donate, please visit www.newbornpossibilities.com/donate.asp

FDA Approves New Treatment for a Type of Late-Stage Skin Cancer

/PRNewswire/ --The U.S. Food and Drug Administration today approved Yervoy (ipilimumab) to treat patients with late-stage (metastatic) melanoma, the most dangerous type of skin cancer.

Melanoma is the leading cause of death from skin disease. An estimated 68,130 new cases of melanoma were diagnosed in the United States during 2010 and about 8,700 people died from the disease, according to the National Cancer Institute.

"Late-stage melanoma is devastating, with very few treatment options for patients, none of which previously prolonged a patient's life," said Richard Pazdur, M.D., director of the Office of Oncology Drug Products in the FDA's Center for Drug Evaluation and Research. "Yervoy is the first therapy approved by the FDA to clearly demonstrate that patients with metastatic melanoma live longer by taking this treatment."

Yervoy is a monoclonal antibody that blocks a molecule known as cytotoxic T-lymphocyte antigen or CTLA-4. CTLA-4 may play a role in slowing down or turning off the body's immune system, affecting its ability to fight off cancerous cells. Yervoy may work by allowing the body's immune system to recognize, target, and attack cells in melanoma tumors. The drug is administered intravenously.

Yervoy's safety and effectiveness were established in a single international study of 676 patients with melanoma. All patients in the study had stopped responding to other FDA-approved or commonly used treatments for melanoma. In addition, participants had disease that had spread or that could not be surgically removed.

The study was designed to measure overall survival, the length of time from when this treatment started until a patient's death. The randomly assigned patients received Yervoy plus an experimental tumor vaccine called gp100, Yervoy alone, or the vaccine alone.

Those who received the combination of Yervoy plus the vaccine or Yervoy alone lived an average of about 10 months, while those who received only the experimental vaccine lived an average of 6.5 months.

Common side effects that can result from autoimmune reactions associated with Yervoy use include fatigue, diarrhea, skin rash, endocrine deficiencies (gland or hormone), and inflammation of the intestines (colitis). Severe to fatal autoimmune reactions were seen in 12.9 percent of patients treated with Yervoy. When severe side effects occurred, Yervoy was stopped and corticosteroid treatment was started. Not all patients responded to this treatment. Patients who did respond in some cases did not see any improvement for several weeks.

Due to the unusual and severe side effects associated with Yervoy, the therapy is being approved with a Risk Evaluation and Mitigation Strategy to inform health care professionals about these serious risks. A medication guide will also be provided to patients to inform them about the therapy's potential side effects.

Yervoy is marketed by New York City-based Bristol-Myers Squibb.

FDA approves Zostavax vaccine to prevent shingles in individuals 50 to 59 years of age

The Food and Drug Administration (FDA) today approved the use of Zostavax, a live attenuated virus vaccine, for the prevention of shingles in individuals 50 to 59 years of age. Zostavax is already approved for use in individuals 60 years of age and older.

In the United States shingles affects approximately 200,000 healthy people between the ages of 50 and 59, per year. It is a disease caused by the varicella-zoster virus, which is a virus in the herpes family and the same virus that causes chickenpox. After an attack of chickenpox, the virus lies dormant in certain nerves in the body. For reasons that are not fully understood, the virus can reappear in the form of shingles, more commonly in people with weakened immune systems and with aging.

"The likelihood of shingles increases with age. The availability of Zostavax to a younger age group provides an additional opportunity to prevent this often painful and debilitating disease" said Karen Midthun, M.D., director of FDA's Center for Biologics Evaluation and Research.

Shingles is characterized by a rash of blisters, which generally develop in a band on one side of the body and can cause severe pain that may last for weeks, and in some people, for months or years after the episode.

Approval was based on a multicenter study conducted in the United States and four other countries in approximately 22,000 people who were 50-59 years of age. Half received Zostavax and half received a placebo. Study participants were then monitored for at least one year to see if they developed shingles. Compared with placebo, Zostavax reduced the risk of developing shingles by approximately 70 percent.

The most common side effects observed in the study were redness, pain and swelling at the site of injection, and headache.

Zostavax was originally approved on May 26, 2006, for the prevention of shingles in individuals 60 years of age and older.

Zostavax is manufactured by Merck & Co. Inc., of Whitehouse Station, New Jersey.

American Heart Association Meeting Report- Metabolic Abnormalities in Obese Teens May Relate to Poor Diets

/PRNewswire/ -- Obese teens may feel healthy, but blood tests show they have inflammation, insulin resistance, and high homocysteine levels, researchers report at the American Heart Association's Nutrition, Physical Activity and Metabolism/Cardiovascular Disease Epidemiology and Prevention 2011 Scientific Sessions.

"The metabolic abnormalities suggest that the process of developing heart disease has already started in these children, making it critical for them to make definitive lifestyle and diet changes," said Ashutosh Lal, M.D., senior author of the study and a pediatric hematologist at the Children's Hospital and Research Center Oakland in California.

Researchers compared the diets and blood test results of 33 obese youths (ages 11 to 19) with 19 age-matched youths of normal weight. Obesity in youths is a body mass index (BMI) higher than the 95th percentile of children the same age. Normal weight youths had a BMI below the 85th percentile. Body mass index is a measure of weight related to height. Two thirds of the participants in both groups were girls. All of the participants were receiving regular health maintenance care at an inner city clinic in Oakland.

Blood tests revealed that the obese teens had:

* C-reactive protein levels almost ten times higher than controls, indicating more inflammation in the body.
* Insulin resistance, a precursor to type 2 diabetes, with greater amounts of insulin needed to keep blood sugar levels normal.
* Homocysteine levels 62 percent higher than controls. High levels of the amino acid homocysteine are related to greater heart disease risk.
* Total glutathione levels 27.9 percent lower than controls, with oxidized glutathione levels 125 percent higher. A higher ratio of oxidized to non-oxidized glutathione indicates oxidative stress, an imbalance in the production of cell-damaging free radicals and the body's ability to neutralize them. Oxidative stress leads to more inflammation and an increase in blood vessel damage and stiffening.


"Looking at the numbers you would think these children might feel sick, but they did not," Lal said. "They are apparently feeling well, but there is a lot going on beneath the surface."

Dietary quality was poor in all the children – low in fresh produce, fiber, and dairy products. On questionnaires, obese and normal-weight children reported consuming similar amounts of grains, proteins, fats and total calories. However, the obese children reported significantly fewer servings of dairy products and tended towards fewer fruit servings. The obese children's diets were lower in potassium, vitamin C, vitamin D, and vitamin A, found in fortified dairy products and as well as in deeply colored fruits and vegetables.

With such poor dietary quality in both the obese and control groups, clinicians should pay more attention to what their young patients are eating, researchers said.

"Obese teens were consuming too few of the natural sources of anti-oxidants, fruits and vegetables, and may have increased antioxidant needs based on the inflammation associated with their extra adiposity," Lal said. "For their heart health, obese teens need to eat better, not just eat less."

Though the study's participants attended an inner city health clinic, researchers said the metabolic differences between obese and normal-weight teens would be found in all socioeconomic groups.

The children in the study were racially diverse. The obese group was 39 percent African-American, 30 percent non-African-American Hispanic, 18 percent Caucasian and 6 percent Asian and 7 percent other. The control group was 21 percent African-American, 5 percent Hispanic, 42 percent Caucasian, 21 percent Asian and 11 percent other.

This study was funded by the Clinical and Translational Science Institute, University of California, San Francisco, and the Bruce and Giovanna Ames Foundation.

FDA approves Benlysta to treat lupus

The U.S. Food and Drug Administration today approved Benlysta (belimumab) to treat patients with active, autoantibody-positive lupus (systemic lupus erythematosus) who are receiving standard therapy, including corticosteroids, antimalarials, immunosuppressives, and nonsteroidal anti-inflammatory drugs.

Benlysta is delivered directly into a vein (intravenous infusion) and is the first inhibitor designed to target B-lymphocyte stimulator (BLyS) protein, which may reduce the number of abnormal B cells thought to be a problem in lupus.

Prior to Benlysta, FDA last approved drugs to treat lupus, Plaquenil (hydroxychloroquine) and corticosteroids, in 1955. Aspirin was approved to treat lupus in 1948.

Lupus is a serious, potentially fatal, autoimmune disease that attacks healthy tissues. It disproportionately affects women, and usually develops between ages 15 and 44. The disease affects many parts of the body including the joints, the skin, kidneys, lungs, heart, and the brain. When common lupus symptoms appear (flare) they can present as swelling in the joints or joint pain, light sensitivity, fever, chest pain, hair loss, and fatigue.

Estimates vary on the number of lupus sufferers in the United States ranging from approximately 300,000 to 1.5 million people. People of all races can have the disease; however, African American women have a 3 times higher incidence (number of new cases) than Caucasian women.

“Benlysta, when used with existing therapies, may be an important new treatment approach for health care professionals and patients looking to help manage symptoms associated with this disease,” said Curtis Rosebraugh, M.D., M.P.H., director of the Office of Drug Evaluation II in the FDA’s Center for Drug Evaluation and Research.

Two clinical studies involving 1,684 patients with lupus demonstrated the safety and effectiveness of Benlysta. The studies diagnosed patients with active lupus and randomized them to receive Benlysta plus standard therapy, or an inactive infused solution (placebo) plus standard therapy. The studies excluded patients who had received prior B-cell targeted therapy or intravenous cyclophosphamide, and those who had active lupus involving the kidneys or central nervous system.

Patients treated with Benlysta and standard therapies experienced less disease activity than those who received a placebo and standard of care medicines. Results suggested, but did not definitively establish, that some patients had a reduced likelihood of severe flares, and some reduced their steroid doses.

African American patients and patients of African heritage participating in the two studies did not appear to respond to treatment with Benlysta. The studies lacked sufficient numbers to establish a definite conclusion. To address this concern, the sponsor has agreed to conduct an additional study of people with those backgrounds to further evaluate the safety and effectiveness of Benlysta for this subgroup of lupus patients.

Those receiving Benlysta during clinical studies reported more deaths and serious infections compared with placebo. The drug should not be administered with live vaccines. The manufacturer is required to provide a Medication Guide to inform patients of the risks associated with Benlysta.

The most common side effects in the studies included nausea, diarrhea, and fever (pyrexia). Patients also commonly experienced infusion reactions, so pre-treatment with an antihistamine should be considered.

Human Genome Sciences Inc., based in Rockville, Md., developed Benlysta and will co-market the drug in the United States with GlaxoSmithKline of Philadelphia.
