(Press-News.org) SAN FRANCISCO, CA, December 6, 2014--In a late-stage clinical trial, Hodgkin lymphoma (HL) patients who received brentuximab vedotin (BV) post-transplant lived longer without disease progression than patients who received only supportive care. This is the first time a study has demonstrated that adding a maintenance therapy after transplant can improve outcomes. The study, led by Craig H. Moskowitz, MD, Clinical Director of the Division of Hematologic Oncology at Memorial Sloan Kettering Cancer Center, was presented today at the 56th Annual Meeting of the American Society of Hematology.
For the past 20 years, high doses of chemotherapy followed by an autologous transplant -- a procedure in which a patient's own blood-forming stem cells are collected and then transplanted back into the patient to produce new, healthy blood cells -- has been the standard of care for patients with HL who have relapsed or did not respond to initial therapy. This treatment approach typically cures about half of patients. For the other half of patients who remain at risk of disease progression after transplant, there is currently no standard therapy.
"Immense progress has been made to reduce complications for transplant patients," said Dr. Moskowitz. "For most people, a transplant can cure disease. But despite our best efforts, improvements in outcomes have plateaued and new therapies are needed."
BV is an antibody that targets the CD30 protein, which is found on HL cells. A total of 327 patients were randomized to receive either the drug or best supportive care after transplant. All patients had either relapsed or failed to respond to at least one prior therapy but were in remission or had stable, non-progressing disease after salvage chemotherapy prior to transplant.
After a median follow-up of two years, patients who received BV had a 20 percent improvement without disease progression compared to those who did not receive the drug (progression-free survival rate of 65 percent vs. 45 percent); 88 percent of patients who received BV are still alive. Adverse events occurred in less than 15 percent of patients and included peripheral sensory neuropathy, upper respiratory tract infection, neutropenia, and fatigue.
"The results of this trial have the potential to change current practice," said Dr. Moskowitz. "I am excited about the prospect of bringing this new therapy to all patients with hard-to-treat Hodgkin lymphoma."

COLUMBIA, Mo. - Unconventional oil and gas (UOG) operations combine directional drilling and hydraulic fracturing, or "fracking," to release natural gas from underground rock. Recent discussions have centered on potential air and water pollution from chemicals used in these processes and how it affects the more than 15 million Americans living within one mile of UOG operations. Now, Susan C. Nagel, a researcher with the University of Missouri, and national colleagues have conducted the largest review to date of research centered on fracking byproducts and their effects ...
Researchers from the University of Hawai'i (UH) and NOAA's Office of National Marine Sanctuaries today announced the discovery of an intact "ghost ship" in 2,000 feet of water nearly 20 miles off the coast of Oahu. Sitting upright, its solitary mast still standing and the ship's wheel still in place, the hulk of the former cable ship Dickenson, later the USS Kailua, was found on the seabed last year on a maritime heritage submersible mission with the UH Hawai'i Undersea Research Laboratory's (HURL) Terry Kerby and Drs. James Delgado and Hans Van Tilburg of the maritime ...
Cold Spring Harbor, NY - Scientists at Cold Spring Harbor Laboratory (CSHL) have devised a powerful algorithm that improves the effectiveness of an important research technology harnessing RNA interference, or RNAi.
Discovered in the late 1990s, RNAi is a naturally occurring biological mechanism in which short RNA molecules bind to and "interfere" with messages sent by genes that contain instructions for protein production. Such interference can prevent a gene from being expressed. In addition to helping regulate gene expression, the RNAi pathway in many species, ...
LA JOLLA-Pain typically has a clear cause-but not always. When a person touches something hot or bumps into a sharp object, it's no surprise that it hurts. But for people with certain chronic pain disorders, including fibromyalgia and phantom limb pain, a gentle caress can result in agony.
In a major breakthrough, a team led by researchers at the Salk Institute and Harvard Medical School have identified an important neural mechanism in the spinal cord that appears to be capable of sending erroneous pain signals to the brain.
By charting the spinal circuits that process ...
When you go to bed and how long you sleep at a time might actually make it difficult for you to stop worrying, according to researchers at Binghamton University. The study, led by Binghamton Anxiety Clinic Director Meredith Coles and graduate student Jacob Nota, found that people who sleep for shorter periods of time and go to bed very late at night are often overwhelmed with more negative thoughts than those who keep more regular sleeping hours. The findings appear in Springer's journal Cognitive Therapy and Research, being published this month.
People are said to have ...
ANN ARBOR--An odd, iridescent material that's puzzled physicists for decades turns out to be an exotic state of matter that could open a new path to quantum computers and other next-generation electronics.
Physicists at the University of Michigan have discovered or confirmed several properties of the compound samarium hexaboride that raise hopes for finding the silicon of the quantum era. They say their results also close the case of how to classify the material--a mystery that has been investigated since the late 1960s.
The researchers provide the first direct evidence ...
(MEMPHIS, Tenn. - December 5, 2014) An international research collaborative has determined that a promising anti-malarial compound tricks the immune system to rapidly destroy red blood cells infected with the malaria parasite but leave healthy cells unharmed. St. Jude Children's Research Hospital scientists led the study, which appears in the current online early edition of the Proceedings of the National Academy of Sciences (PNAS).
The compound, (+)-SJ733, was developed from a molecule identified in a previous St. Jude-led study that helped to jumpstart worldwide anti-malarial ...
This news release is available in Spanish. This is a pioneering study in the world of the physiology of exercise, given that it describes for the first time that elite Kenyan athletes have greater brain oxygenation during periods of maximum physical effort, and which contributes to their success in long-distance races.
Doctor Jordan Santos-Concejero, of the Department of Physical Education and Sport at the UPV/EHU, carried out research the aim of which was to analyse the response of cerebral oxygenation at maximum and progressive rhythms amongst elite Kenyan runners ...
Pretty soon, powering your tablet could be as simple as wrapping it in cling wrap.
That's Illan Kramer's hope. Kramer and colleagues have just invented a new way to spray solar cells onto flexible surfaces using miniscule light-sensitive materials known as colloidal quantum dots (CQDs)--a major step toward making spray-on solar cells easy and cheap to manufacture.
"My dream is that one day you'll have two technicians with Ghostbusters backpacks come to your house and spray your roof," says Kramer, a post-doctoral fellow with The Edward S. Rogers Sr. Department of Electrical ...
This news release is available in German. The consumption of a sugary banquet before sex can have far-reaching consequences for a fruit fly and its offspring: it makes the young flies more prone to obesity. Together with researchers from Spain and Sweden, scientists from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg have discovered that even a brief change in the diet of male fruit flies triggers obesity in the next generation. Specifically, high-sugar nutrition consumed one to two days before mating causes the male offspring to accumulate more ...
