ScienceDaily (Oct. 1, 2012) A novel therapy in the early stages of development at Virginia Commonwealth University Massey Cancer Center shows promise in providing lasting protection against the progression of multiple myeloma following a stem cell transplant by making the cancer cells easier targets for the immune system.

Outlined in the British Journal of Hematology, the Phase II clinical trial was led by Amir Toor, M.D., hematologist-oncologist in the Bone Marrow Transplant Program and research member of the Developmental Therapeutics program at VCU Massey Cancer Center. The multi-phased therapy first treats patients with a combination of the drugs azacitidine and lenalidomide. Azacitidine forces the cancer cells to express proteins called cancer testis antigens (CTA) that immune system cells called T-cell lymphocytes recognize as foreign. The lenalidomide then boosts the production of T-cell lymphocytes. Using a process called autologous lymphocyte infusion (ALI), the T-cell lymphocytes are then extracted from the patient and given back to them after they undergo a stem cell transplant to restore the stem cells' normal function. Now able to recognize the cancer cells as foreign, the T-cell lymphocytes can potentially protect against a recurrence of multiple myeloma following the stem cell transplant.

"Every cell in the body expresses proteins on their surface that immune system cells scan like a barcode in order to determine whether the cells are normal or if they are foreign. Because multiple myeloma cells are spawned from bone marrow, immune system cells cannot distinguish them from normal healthy cells," says Toor. "Azacitidine essentially changes the barcode on the multiple myeloma cells, causing the immune system cells to attack them," says Toor.

The goal of the trial was to determine whether it was safe, and even possible, to administer the two drugs in combination with an ALI. In total, 14 patients successfully completed the investigational drug therapy. Thirteen of the participants successfully completed the investigational therapy and underwent a stem cell transplant. Four patients had a complete response, meaning no trace of multiple myeloma was detected, and five patients had a very good partial response in which the level of abnormal proteins in their blood decreased by 90 percent.

In order to determine whether the azacitidine caused an increased expression of CTA in the multiple myeloma cells, Toor collaborated with Masoud Manjili, D.V.M., Ph.D., assistant professor of microbiology and immunology at VCU Massey, to conduct laboratory analyses on bone marrow biopsies taken from trial participants before and after treatments. Each patient tested showed an over-expression of multiple CTA, indicating the treatment was successful at forcing the cancer cells to produce these "targets" for the immune system.

"We designed this therapy in a way that could be replicated, fairly inexpensively, at any facility equipped to perform a stem cell transplant," says Toor. "We plan to continue to explore the possibilities of immunotherapies in multiple myeloma patients in search for more effective therapies for this very hard-to-treat disease."

In addition to Manjili, Toor collaborated with John McCarty, M.D., director of the Bone Marrow Transplant Program at VCU Massey, and Harold Chung, M.D., William Clark, M.D., Catherine Roberts, Ph.D., and Allison Hazlett, also all from Massey's Bone Marrow Transplant Program; Kyle Payne, Maciej Kmieciak, Ph.D., from Massey and the Department of Microbiology and Immunology at VCU School of Medicine; Roy Sabo, Ph.D., from VCU Department of Biostatistics and the Developmental Therapeutics program at Massey; and David Williams, M.D., Ph.D., from the Department of Pathology at VCU School of Medicine, co-director of the Tissue and Data Acquisition and Analysis Core and research member of the Developmental Therapeutics program at Massey.

RBCC: Could Stem Cells Hold the Key to Treating Traumatic Brain Injuries?

For more than 40 years, Lesley Kelly of Glasgow, Scotland, lived with third-degree burns that stretched over 60 percent of her body.

Kelly was 2 years old when she fell into a bathtub filled with hot water that scorched most of the right side of her body. She lost full range of motion around many of her joints.

"When you have bad scarring, the buildup is very thick and has no elasticity," said Kelly, 45, whose right elbow was most affected by the buildup of scar tissue. "The problem with thermal burn scarring [is that] it's hard to get the range of motion."

Kelly underwent numerous reparative surgeries through the years, but the scar tissue continued to grow back. The procedures did not lessen the look of her scars.

In 2011, Kelly underwent a new, experimental procedure that used stem cells from her own fat tissue to repair the buildup around her right elbow.

Surgeons cleaned the scar buildup around the elbow and used liposuction to pull fat from off Kelly's waist. They separated the fat cells from the stem and regenerative cells, which were then injected into the wound on Kelly's arm. The procedure took less than two hours.

Within months, Kelly was able to regain 40 degrees of motion that she had lost more than 40 years ago.

"If this technology was available earlier in my life, my scars would not have been as bad," said Kelly.

There are an estimated 50,000 to 70,000 burn cases each year in the U.S., according to the American Burn Association.

The stem cell therapy, approved in the U.K. to treat soft tissue wounds, is now gaining traction in the U.S.

Experimental Stem Cell Therapy May Help Burn Victims

IRVINE, CA--(Marketwire - Oct 1, 2012) - Oct. 3 marks International Stem Cell Awareness Day, a global celebration where leading scientists, researchers and supporters will acknowledge the scientific advances of stem cell research and its ability to potentially treat a variety of diseases and injuries in the 21st century. This dedicated community is committed to unlocking the potential of stem cells and has made significant strides since the discovery of a method to grow human stem cells less than 15 years ago.

"This is a critical and historic time for stem cell research," said Peter Donovan, Ph.D., director, Sue & Bill Gross Stem Cell Research Center, UC Irvine. "We're literally on the brink of developing new treatments for some of the world's most devastating diseases and injuries. The act of simply raising awareness about this research is one of the best things people can do to help accelerate the process. This event is a great opportunity for everyone to help spread the word and build momentum through a timely mass effort."

Scientists at UC Irvine and other research facilities around the globe continue to work diligently to develop therapies to treat life threatening and debilitating conditions such as Alzheimer's disease, multiple sclerosis, macular degeneration, cancer, Huntington's disease, Parkinson's disease, brain disorders and paralysis caused by spinal cord injuries. These efforts continue to give hope to millions who suffer from these devastating conditions by offering revolutionary treatments and potential cures.

There are several research programs taking place at the Sue & Bill Gross Stem Cell Research Center at UC Irvine that continue to break down barriers and open doors to new treatments for major diseases and injuries:

Spinal Cord and Traumatic Brain Injuries: Neurobiologist Hans Keirstead, Ph.D., as well as husband and wife scientists Aileen Anderson, Ph.D., and Brian Cummings, Ph.D., are conducting stem cell studies to develop treatments for the more than 1.3 million Americans who suffer from spinal cord injuries. Their advancements have led to the world's first clinical trial of human neural stem cell-based therapy for chronic spinal cord injuries (Anderson/Cummings) and the first FDA approved clinical trials using embryonic stem cells (Keirstead). Their research is significant because no drug or other forms of treatment have been able to restore function for those suffering from paralysis. In addition, Cummings and Anderson are applying their stem research to traumatic brain injury, a leading cause of death and disability worldwide, especially in children and young adults.

Alzheimer's Disease: An estimated 35 million people worldwide suffer from Alzheimer's disease, five million of whom live in the U.S. Frank LaFerla, Ph.D., director of UC Irvine's Institute for Memory Impairments and Neurological Disorders, and Matthew Blurton-Jones, Ph.D., of the Sue & Bill Gross Stem Cell Research Center, UC Irvine, have shown for the first time that neural stem cells can rescue memory in mice with advanced Alzheimer's disease, raising hope for a potential treatment in humans. Their work is expected to move to clinical trials in less than five years.

Huntington's Disease: Huntington's disease is a degenerative and ultimately fatal brain disorder that takes away a person's ability to walk, talk and reason. It affects about 30,000 people in the U.S. with another 200,000 or more likely to inherit the disorder. Leslie Thompson, Ph.D., and her team of researchers are currently investigating new stem cell lines and techniques to support the area of the brain that is susceptible to the disease with the hope of developing a cure for future generations.

Macular Degeneration, Retinitis Pigmentosa and Inherited Blindness: Henry Klassen, M.D., Ph.D. has focused his stem cell research on regenerating damaged retinal tissue to restore sight to people suffering from retinitis pigmentosa (an inherited form of degenerative eye disease) and macular degeneration which usually affects older people and leads to loss of vision. Macular degeneration affects millions of Americans. His work hopes to find cures and treatments for corneal and retinal eye disease.

New Website Helps Spread the Word Online To commemorate International Stem Cell Awareness Day and encourage support of stem cell research, an interactive website has been created. Advocates are asked to visit http://www.StemCellsOfferHope.com and share online a wide range of key facts, downloadable images and links to other valuable resources within their social networks.

International Stem Cell Awareness Day Events at UC Irvine The Sue & Bill Gross Stem Cell Research Center at UC Irvine will celebrate International Stem Cell Awareness Day by hosting three special events. An open house will take place on Oct. 1 for high school students. A UC Irvine student, faculty and staff open house will take place on Oct. 2. Finally, an all-day science symposium on Oct. 3 will feature a "Meet the Scientist" interactive forum. The forum and symposium are open to all UC Irvine scientists, clinicians, graduate students, post-docs and members of the community. To RSVP for any these events or for more information, include the name of the event in the subject line and email stemcell@research.uci.edu.
